- Objective: To investigate to what degree adolescent males (1) value confidentiality, (2) experience confidentiality and are comfortable asking sensitive questions when visiting a general practitioner (GP), and (3) whether self-reported symptoms of poor mental health and health-compromising behaviours (HCB) affect these states of matters.Design: Cross-sectional.Setting: School-based census on life, health and primary care in Region Sörmland, Sweden.Subjects: 2,358 males aged 15–17 years (response rate 84%).Main outcome measures: The impact of poor mental health and HCBs on adolescent males’ valuing and experiencing private time with the GP, having professional secrecy explained, and being comfortable asking about the body, love and sex, analysed with structural equation modelling.Results: Almost all respondents valued confidentiality regardless of their mental health or whetherthey engaged in HCBs: 86% valued spending private time with the GP, and 83% valued receivinga secrecy explanation. Among those who had visited a GP in the past year (n¼1,200), 74% had experienced private time and 42% a secrecy explanation. Three-quarters were at least partly comfortable asking sensitive questions. Adolescent males with HCBs were more likely to experience a secrecy explanation (approximative odds ratio [appOR] 1.26;p¼0.005) and to be comfortable asking about sex than their peers (appOR 1.22;p¼0.007). Respondents reporting experienced confidentiality were more comfortable asking sensitive questions (appOR 1.25–1.54;p0.010).Conclusion: Confidentiality matters regardless of poor mental health or HCBs and makes adolescent males more comfortable asking sensitive questions. We suggest that GPs consistently offerprivate time and explain professional secrecy.KEY POINTSConfidentiality for adolescent males has been scantily studied in relation to mental healthand health-compromising behaviours.In this study, most adolescent males valued confidentiality, regardless of their mental healthand health-compromising behaviours.Health-compromising behaviours impacted only slightly, and mental health not at all, on experiences of confidentiality in primary care.When provided private time and an explanation of professional secrecy, adolescent males were more comfortable asking the GP sensitive questions.

Generalized joint hypermobility and the risk of pregnancy‐related pelvic girdle pain : Is body mass index of importance?—A prospective cohort study
- 2023
-
In: Acta Obstetricia et Gynecologica Scandinavica. - : John Wiley & Sons. - 0001-6349 .- 1600-0412. ; 102:10, s. 1259-1268

Journal article (peer-reviewed)abstract
- Introduction: Pelvic girdle pain (PGP) affects approximately 50% of pregnant women. The mechanisms are multifactorial but not fully understood. Women with generalized joint hypermobility (GJH) may be vulnerable to load in the pelvic joints during pregnancy. Our aim was to investigate if women with GJH had an increased risk of PGP and higher pain intensity during and after pregnancy, compared with women with normal joint mobility. We also studied if body mass index (BMI) in early pregnancy influenced that risk.Material and methods: A prospective cohort study of 356 women, whose data were collected by self-reports and clinical examinations in early and in late pregnancy and 9 months after childbirth. GJH was present with ≥5/9 points on the Beighton score. PGP was defined by a pain drawing and ≥1 positive test. Pain intensity was measured with a visual analogue scale (0-100 mm). We adjusted for age and origin in logistic regression and ordinal logistic regression analysis.Results: In early pregnancy, 47.1% of the women with GJH had PGP vs 32.6% of women with normal joint mobility (adjusted odds ratio [aOR] 1.76; 95% confidence interval [CI] 0.86-3.62) and had higher odds of reporting higher pain intensity (aOR 2.04; 95% CI 1.02-4.07). The odds of PGP were highest for women with GJH and BMI ≥25 kg/m2 (aOR 6.88; 95% CI 1.34-35.27) compared with women with normal joint mobility and BMI <25 kg/m2 . The estimated associations were weaker and not statistically significant in late pregnancy or after childbirth.Conclusions: Women with GJH did not have an increased risk of PGP during or after pregnancy but reported higher pain intensity in early pregnancy compared with women with normal joint mobility. Since women with combined GJH and BMI ≥25 kg/m2 had the highest odds of PGP in early pregnancy, our results may suggest that health care needs to pay attention to and develop methods to reduce the risk of PGP and delay the onset of pain during pregnancy in women with this combination.Keywords: Uppsala pelvic pain study; body mass index; generalized joint hypermobility; pelvic girdle pain; pregnancy.

Journal article (peer-reviewed)abstract
- Background Pelvic girdle pain (PGP) is common during pregnancy but the causes remain poorly understood. Generalized joint hypermobility (GJH) is an inherited trait, with joint mobility beyond normal limits and is assumed to be related with PGP. The aim of this project was to study the association between self-reported GJH and the presence of PGP during pregnancy. Methods In this cohort study, 4884 Swedish-speaking women were consecutively recruited at their first visit for registration in the national antenatal screening programme in Sweden. We used the five-part questionnaire (5PQ) to assess GJH and pain drawings to identify PGP. Our primary outcome was the presence of PGP during the entire pregnancy and secondary outcomes were PGP in each trimesters. We tested the associations with logistic regression analysis, and adjusted for age and ethnicity. Results In all,2455 (50.3%) women responded to both questionnaires. The prevalence of self-reported GJH was 28.7%. A higher proportion of women with GJH than women without GJH reported PGP during the entire pregnancy (47.9% vs. 41.0%), particularly in trimester 1 (31.6% vs. 22.0%). Thus, women with GJH also had higher odds of PGP during the entire pregnancy (adjusted odds ratio (aOR) 1.27: 95% CI 1.11-1.47) and in trimester 1 (aOR 1.54: 95% CI 1.20-1.96), but the associations were not statistically significant in trimester 2 (aOR 1.24: 95% CI 0.82-1.88) or trimester 3 (aOR 1.20: 95% CI 0.99-1.45). The odds of PGP in pregnancy increased with increasing numbers of positive answers to the 5PQ (pfor linear trend < 0.001) for the entire pregnancy and in trimester 1 (pfor linear trend < 0.001), but not in trimesters 2 or 3 (p = 0.13 andp = 0.06, respectively). Conclusions Compared to women with normal joint mobility, women with GJH had higher odds of reporting PGP during pregnancy and the odds increased with number of positive responses to the 5PQ. The associations were present in trimester 1 but did not reach statistical significance in trimester 2 and 3.

The relationship between self-efficacy and transition to work or studies in young adults with disabilities
- 2018
-
In: Scandinavian Journal of Public Health. - : Sage Publications. - 1403-4948 .- 1651-1905. ; 46:2, s. 272-278
-
Journal article (peer-reviewed)abstract
- Aim: To investigate perceived self-efficacy in unemployed young adults with disabilities and the association between self-efficacy and transition to work or studies. Methods: This prospective cohort study collected data through self-report questionnaires and registry data from a vocational rehabilitation project with young adults, aged 19-29 years. The Swedish Social Insurance Agency, the Swedish Public Employment Service and the participating municipalities identified potential participants to the study. A total of 531 participants were included in the study, of which 249 (47%) were available for analysis. Multinomial logistic regression models were carried out to estimate the associations between self-efficacy, demographic, health and employment status. The latter was coded as: “no transition to work or studies”, “transition to studies”, and “transition to work”.Results: A higher level of self-efficacy was associated with increased odds for “transition to work” (OR=2.37, p<0.05). This finding remained consistent when adjusting for possible confounders. The mean value of self-efficacy was low, and participants with lower self-efficacy reported worse self-rated health (p<0.001) compared with participants with higher self-efficacy.Conclusions: The results from this study suggest that self-efficacy should be addressed in vocational rehabilitation of young adults with disabilities in order to support their transition and integration into the labour market.

Journal article (peer-reviewed)abstract
- Background: It is unclear whether moderate differences in dietary carbohydrate quantity and quality influence plasma FAs in the lipogenic pathway in healthy adults.Objectives: We investigated the effects of different carbohydrate quantities and quality on plasma palmitate concentrations (primary outcome) and other saturated and MUFAs in the lipogenic pathway.Methods: Twenty healthy participants were randomly assigned, and 18 (50% women; age: 22-72 y; BMI: 18.2-32.7 kg/m2 and BMI was measured in kg/m2) started the cross-over intervention. During each 3-wk period (separated by a 1-wk washout period), 3 diets were consumed (all foods provided) in random order: low-carbohydrate (LC) (38% energy (E) carbohydrates, 25-35 g fiber/d, 0% E added sugars); high-carbohydrate/high-fiber (HCF) (53% E carbohydrates, 25-35 g fiber/d, 0% E added sugars); and high-carbohydrate/high-sugar (HCS) (53% E carbohydrates, 19-21 g fiber/d, 15% E added sugars). Individual FAs were measured proportionally to total FAs by GC in plasma cholesteryl esters, phospholipids, and TGs. False discovery rate-adjusted repeated measures ANOVA [ANOVA-false discovery rate (FDR)] was used to compare outcomes.Results: The self-reported intakes of carbohydrates and added-and free sugars were; 30.6% E and 7.4% E in LC, 41.4% E and 6.9% E in HCF, and 45.7% E and 10.3% in HCS. Plasma palmitate did not differ between the diet periods (ANOVA FDR P > 0.43, n = 18). After HCS, myristate concentrations in cholesterol esters and phospholipids were >= 19% higher than LC and >= 22% higher than HCF (P = 0.005). After LC, palmitoleate in TG was 6% lower compared with HCF and 7% compared with HCS (P = 0.041). Body weight differed (<= 0.75 kg) between diets before FDR correction.Conclusions: Different carbohydrate quantity and quality do not influence plasma palmitate concentrations after 3 wk in healthy Swedish adults, whereas myristate increased after the moderately higher intake of carbohydrate/high-sugar, but not carbohydrate/high-fiber. Whether plasma myristate is more responsive than palmitate to differences in carbohydrate intake requires further study, especially considering that participants deviated from the planned dietary targets.

Poor peer relations in adolescence, social support in early adulthood, and depressive symptoms in later adulthood : evaluating mediation and interaction using four-way decomposition analysis
- 2019
-
In: Annals of Epidemiology. - : Elsevier BV. - 1047-2797 .- 1873-2585. ; 29, s. 52-59
-
Journal article (peer-reviewed)abstract
- Purpose: Supportive social relations are associated with good mental health, yet few studies have considered the prospective importance of adolescent peer relations for adult mental health and the potential mechanisms involved.Methods: Participants (n=941) were sourced from the Northern Swedish Cohort, a prospective study comprising school students aged 16 in 1981. Integrating life course epidemiology with four-way decomposition analysis, this paper considers the controlled direct effect of poor peer relations at age 16 on depressive symptoms at age 43, the pure indirect effect mediated by the availability of social support at age 30, and potential interactions between the exposure and the mediator.Results: After controlling for gender, baseline depressive symptoms and parental socioeconomic position, poor peer relations at age 16 were associated with depressive symptoms at age 43, largely irrespective of social support at age 30. Nonetheless, poor peer relations in adolescence were associated with poorer social support at age 30, and mediation accounted for a modest proportion (pure indirect effect 10%) of the association between poor peer relations and depressive symptoms at age 43.Conclusions: Policies to foster constructive peer relations for adolescents at school are encouraged; such policies may promote both the availability of social support and better mental health across the life course.

Design of a randomized controlled trial of physical training and cancer (Phys-Can) - the impact of exercise intensity on cancer related fatigue, quality of life and disease outcome
- 2017
-
In: BMC Cancer. - : Springer Science and Business Media LLC. - 1471-2407. ; 17:1, s. 1-12
-
Journal article (peer-reviewed)abstract
- Background: Cancer-related fatigue is a common problem in persons with cancer, influencing health-related quality of life and causing a considerable challenge to society. Current evidence supports the beneficial effects of physical exercise in reducing fatigue, but the results across studies are not consistent, especially in terms of exercise intensity. It is also unclear whether use of behaviour change techniques can further increase exercise adherence and maintain physical activity behaviour. This study will investigate whether exercise intensity affects fatigue and health related quality of life in persons undergoing adjuvant cancer treatment. In addition, to examine effects of exercise intensity on mood disturbance, adherence to oncological treatment, adverse effects from treatment, activities of daily living after treatment completion and return to work, and behaviour change techniques effect on exercise adherence. We will also investigate whether exercise intensity influences inflammatory markers and cytokines, and whether gene expressions following training serve as mediators for the effects of exercise on fatigue and health related quality of life. Methods/design: Six hundred newly diagnosed persons with breast, colorectal or prostate cancer undergoing adjuvant therapy will be randomized in a 2 × 2 factorial design to following conditions; A) individually tailored low-to-moderate intensity exercise with or without behaviour change techniques or B) individually tailored high intensity exercise with or without behaviour change techniques. The training consists of both resistance and endurance exercise sessions under the guidance of trained coaches. The primary outcomes, fatigue and health related quality of life, are measured by self-reports. Secondary outcomes include fitness, mood disturbance, adherence to the cancer treatment, adverse effects, return to activities of daily living after completed treatment, return to work as well as inflammatory markers, cytokines and gene expression. Discussion: The study will contribute to our understanding of the value of exercise and exercise intensity in reducing fatigue and improving health related quality of life and, potentially, clinical outcomes. The value of behaviour change techniques in terms of adherence to and maintenance of physical exercise behaviour in persons with cancer will be evaluated.

- Exercise during cancer treatment improves cancer-related fatigue (CRF), but the importance of exercise intensity for CRF is unclear. We compared the effects of high- vs low-to-moderate-intensity exercise with or without additional behavior change support (BCS) on CRF in patients undergoing (neo-)adjuvant cancer treatment. This was a multicenter, 2x2 factorial design randomized controlled trial (Clinical Trials NCT02473003) in Sweden. Participants recently diagnosed with breast (n = 457), prostate (n = 97) or colorectal (n = 23) cancer undergoing (neo-)adjuvant treatment were randomized to high intensity (n = 144), low-to-moderate intensity (n = 144), high intensity with BCS (n = 144) or low-to-moderate intensity with BCS (n = 145). The 6-month exercise intervention included supervised resistance training and home-based endurance training. CRF was assessed by Multidimensional Fatigue Inventory (MFI, five subscales score range 4-20), and Functional Assessment of Chronic Illness Therapy-Fatigue scale (FACIT-F, score range 0-52). Multiple linear regression for main factorial effects was performed according to intention-to-treat, with post-intervention CRF as primary endpoint. Overall, 577 participants (mean age 58.7 years) were randomized. Participants randomized to high- vs low-to-moderate-intensity exercise had lower physical fatigue (MFI Physical Fatigue subscale; mean difference −1.05 [95% CI: −1.85, −0.25]), but the difference was not clinically important (ie <2). We found no differences in other CRF dimensions and no effect of additional BCS. There were few minor adverse events. For CRF, patients undergoing (neo-)adjuvant treatment for breast, prostate or colorectal cancer can safely exercise at high- or low-to-moderate intensity, according to their own preferences. Additional BCS does not provide extra benefit for CRF in supervised, well-controlled exercise interventions.

- Objective To study if childhood emotional, physical and sexual abuse are determinants for having an unplanned pregnancy, if the categories of abuse interact, and if a potential bias due to the selection of the participants (collider stratification bias) could explain the effect of childhood abuse.Design A cross-sectional study.Setting The study is based on the Norwegian Mother and Child Cohort Study (MoBa) and uses data from the Medical Birth Registry of Norway.Sample Women participating in the MoBa for the first time, >= 18 years of age who responded to questions regarding childhood abuse and pregnancy planning (n = 76 197).Methods Data were collected using questionnaires. We conducted analyses using modified Poisson regressions and the relative excess risks due to interaction (RERI). Sensitivity analyses were performed.Main outcome measure An unplanned pregnancy (yes/no).Results Exposure to childhood emotional (adjusted relative risk (RR) 1.14, 95% CI 1.10-1.19), physical (adjusted RR 1.11, 95% CI 1.04-1.18) and sexual (adjusted RR 1.20, 95% CI 1.14-1.27) abuse increased the risk of having an unplanned pregnancy. The effects could not be explained by the collider stratification bias. The different combinations of categories of abuse did not show any interaction effects.Conclusions Childhood emotional, physical and sexual abuses separately increase the risk of having an unplanned pregnancy. The results indicate that victims of childhood abuse are in greater need of support to achieve their reproductive goals.

Comparing the Efficacy of Multidisciplinary Assessment and Treatment, or Acceptance and Commitment Therapy, with Treatment as Usual on Health Outcomes in Women on Long-Term Sick Leave : A Randomised Controlled Trial
- 2021
-
In: International Journal of Environmental Research and Public Health. - : MDPI. - 1661-7827 .- 1660-4601. ; 18:4
-
Journal article (peer-reviewed)abstract
- Background: Chronic pain and mental disorders are common reasons for long term sick leave. The study objective was to evaluate the efficacy of a multidisciplinary assessment and treatment program including acceptance and commitment therapy (TEAM) and stand-alone acceptance and commitment therapy (ACT), compared with treatment as usual (Control) on health outcomes in women on long-term sick leave.Method: Participants (n = 308), women of working age on long term sick leave due to musculoskeletal pain and/or common mental disorders, were randomized to TEAM (n = 102), ACT (n = 102) or Control (n = 104). Participants in the multidisciplinary assessment treatment program received ACT, but also medical assessment, occupational therapy and social counselling. The second intervention included ACT only. Health outcomes were assessed over 12 months using adjusted linear mixed models. The results showed significant interaction effects for both ACT and TEAM compared with Control in anxiety (ACT [p < 0.05]; TEAM [p < 0.001]), depression (ACT [p < 0.001]; TEAM [p < 0.001]) and general well-being (ACT [p < 0.05]; TEAM [p < 0.001]). For self-rated pain, there was a significant interaction effect in favour of ACT (p < 0.05), and for satisfaction with life in favour of TEAM (p < 0.001).Conclusion: Both ACT alone and multidisciplinary assessment and treatment including ACT were superior to treatment as usual in clinical outcomes.

Pressure mapping to prevent pressure ulcers in a hospital setting : A pragmatic randomised controlled trial
- 2017
-
In: International Journal of Nursing Studies. - : Elsevier BV. - 0020-7489 .- 1873-491X. ; 72, s. 53-59
-
Journal article (peer-reviewed)abstract
- Background: Pressure ulcers cause suffering to patients and costs to society. Reducing pressure at the interface between the patient's body and the support surface is a valid clinical intervention for reducing the risk of pressure ulcers. However, studies have shown that knowledge of how to reduce pressure and shear and to prevent pressure ulcers is lacking. Objective: To evaluate the effect of a pressure mapping system on pressure ulcer prevalence and incidence in a hospital setting. Design: Pragmatic randomised controlled trial. Setting: A geriatric/internal medical ward with 26 beds in a Swedish university hospital. Participants: 190 patients were recruited (intervention: n = 91; control: n = 99) over a period of 9 months. Patients were eligible if they were over 50 years old, admitted to the ward between Sunday 4 pm and Friday 4 pm, and expected to stay in the ward >= 3 days. Intervention: The continuous bedside pressure mapping system displays the patient's pressure points in real-time colour imagery showing how pressure is distributed at the body mat interface. The system gives immediate feedback to staff about the patient's pressure points, facilitating preventive interventions related to repositioning. It was used from admittance to discharge from the ward (or 14 days at most). Both intervention and control groups received standard pressure ulcer prevention care. Results: No significant difference in the prevalence and incidence of pressure ulcers was shown between intervention and control groups. The prevalence of pressure ulcers in the intervention group was 24.2% on day 1 and 28.2% on day 14. In the control group the corresponding numbers were 18.2% and 23.8%. Seven of 69 patients (10.1%) in the intervention group and seven of 81 patients (8.6%) in the control group who had no pressure ulcers on admission developed category 1 and category 2 ulcers during their hospital stay. The incidence rate ratio between the intervention and control groups was 1.13 (95% CI: 0.34-3.79). Conclusions: This study failed to demonstrate a beneficial effect of a pressure mapping system on pressure ulcer prevalence and incidence. However, the study could have increased staff awareness and focus on pressure ulcer prevention, thus affecting the prevalence and incidence of pressure ulcers in a positive way in both study groups. It is important to further investigate the experience of the multidisciplinary team and the patients regarding their use of the pressure mapping system, as well as strengths and weaknesses of the system.

Exploring adolescent males’ consultations with general practitioners in the context of psychosocial health
- 2024
-
Doctoral thesis (other academic/artistic)abstract
- This thesis aimed to explore adolescent males’ experiences of consultations with general practitioners (GPs) with a particular focus on confidentiality in relation to poor mental health and health-compromising behaviours.First, a model describing the covariation of poor mental-health symptoms, associated somatic symptoms, and health-compromising behaviours was developed through explorative and confirmative factor analysis (paper I). The model was then applied in a structural equation modelling approach to study whether these symptoms and behaviours influenced how adolescent males valued and experienced confidentiality as well as whether they were comfortable asking sensitive questions during their GP consultations (paper II).Next, to gain a deeper understanding, adolescent males’ experiences with GP consultations were further explored through a qualitative lifeworld-based approach. Interviews were analysed with thematic analysis (paper III) and video observations with a phenomenological–hermeneutical method (paper IV). The findings revealed that by providing confidentiality, here defined as private time without parents and explaining the meaning and boundaries of professional secrecy, GPs can facilitate discussions on sensitive topics and make adolescent males feel more comfortable to raise their own concerns. This might be a fruitful approach to address any unmet health needs, which can be achieved through the split-visit consultation model.Another finding was that the studied consultations were very complex. Due to their ongoing development, inexperience with GP consultations, and notions of masculinity, the adolescent males struggled with cognitive, emotional, and relational difficulties while negotiating their right to define the problem and be responsible for their health. The adolescent males emphasized the importance of being listened to and taken seriously, which entails that all aspects of the consultation must be adapted to their individual needs and to their lifeworld. This aligns with Larsen’s consultation model, where the GP strives to understand the patient’s experience and to connect their medical findings to the patient’s lifeworld. Given that both the split-visit consultation model and Larsen’s consultation model offer valuable frameworks for addressing essential, but different, aspects in adolescent males’ GP consultations, the thesis proposes a synthesis of the two approaches.

Understanding adolescent males' poor mental health and health-compromising behaviours : A factor analysis model on Swedish school-based data
- 2022
-
In: Scandinavian Journal of Public Health. - : Sage Publications. - 1403-4948 .- 1651-1905. ; 50:2, s. 232-244
-
Journal article (peer-reviewed)abstract
- AIM: The aim was to develop a factor model of the clustering of poor mental-health symptoms and health-compromising behaviours (HCBs) in adolescent males.METHODS: The study was based on two cross-sectional school-based Swedish surveys in 2011 (response rate 80%, N=2823) and 2014 (response rate 85%, N=2358), both of which comprised questionnaires from males aged 15-16 and 17-18 years. A factor model was developed by exploratory factor analysis on the 2011 survey and validated by confirmatory factor analysis on the 2014 survey.RESULTS: Four aspects of poor mental health and HCBs emerged in the exploratory factor analysis: (a) deviancy as a tendency to substance use and delinquency, (b) unsafety as an inclination towards feelings of unsafety in different environments, (c) gloominess as a tendency towards pessimism and feeling unwell and (d) pain as an inclination to experience physical pain. The model was validated with good model fit. Age did not affect the model structure, but older adolescent males were more influenced by deviancy and gloominess and less by unsafety compared to their younger peers.Conclusions: Separating symptoms of poor mental health and HCBs into four areas - deviancy, unsafety, gloominess and pain - brings new perspectives to the understanding of adolescent males' health. To the best of our knowledge, our factor model is the first to include unsafety and pain in this context. Whenever a comprehensive approach to the health of adolescent males is needed in the clinic or in the field of public health, this factor model may provide guidance.

- Objective To assess socioeconomic differences between patients registered with private and public primary healthcare centres.Design Population-based cross-sectional study controlling for municipality and household.Setting Swedish population-based socioeconomic data collected from Statistics Sweden linked with individual registration data from all 21 Swedish regions.Participants All individuals residing in Sweden on 31 December 2015 (n=9 851 017) were included in the study.Primary outcome measures Registration with private versus public primary healthcare centres.Results After controlling for municipality and household, individuals with higher socioeconomic status were more likely to be registered with a private primary healthcare provider. Individuals in the highest income quantile were 4.9 percentage points (13.7%) more likely to be registered with a private primary healthcare provider compared with individuals in the lowest income quantile. Individuals with 1–3 years of higher education were 4.7 percentage points more likely to be registered with a private primary healthcare provider compared with those with an incomplete primary education.Conclusions The results show that there are notable differences in registration patterns, indicating a skewed distribution of patients and health risks between private and public primary healthcare providers. This suggests that risk selection behaviour occurs in the reformed Swedish primary healthcare system, foremost through location patterns.

Agreement between reported questionnaire data and medical records on diagnosis and COVID-19 symptoms at onset
- 2023
-
In: European Clinical Respiratory Journal. - : Taylor & Francis. - 2001-8525. ; 10:1
-
Journal article (peer-reviewed)abstract
- The aim of this study was to assess whether there was agreement between self-reported data in a survey and medical records regarding diagnoses and symptoms at COVID-19 onset. The impact of sociodemographic factors on agreement between the two data sources was also assessed. Cross-sectional data were extracted from a Swedish longitudinal cohort study. In total, 401 non-hospitalized patients with a polymerase chain reaction-confirmed COVID-19 infection responded to a survey and agreed to a review of their electronic medical records. Agreement, estimated using the kappa statistic, sensitivity, and specificity were calculated for nine diagnoses and eleven symptoms. Differences between subgroups based on sociodemographic factors were assessed. The agreement between the self-reported data and medical records was at a substantial to moderate level for diagnoses such as diabetes mellitus (kappa 0.65, sensitivity 86%) and hypertension (kappa 0.59, sensitivity 56%) and at a fair level for more difficult-to-define conditions such as ongoing immunosuppressive treatment (kappa 0.27, sensitivity 25%). The agreement between the two data sources on symptoms was between fair and poor (kappa 0.36 for fever; kappa 0.05 for fatigue). Agreement for some diagnoses and symptoms varied across some sociodemographic subgroups, e.g. agreement in diabetes mellitus was significantly better in males (kappa 1.0) than females (kappa 0.52, homogeneity tests p = 0.02). In general, kappa values were lower for symptoms than diagnoses. The agreement between the two sources varied with diagnoses and symptoms and was also influenced by sociodemographic factors. This study illustrates that it is important to consider type of data used in the epidemiological studies as different information sources differ with quality and accuracy.

Journal article (peer-reviewed)abstract
- Background: The aim was to investigate inferences of statistically significant test results among persons with more or less statistical education and research experience.Methods: A total of 75 doctoral students and 64 statisticians/epidemiologist responded to a web questionnaire about inferences of statistically significant findings. Participants were asked about their education and research experience, and also whether a 'statistically significant' test result (P = 0.024, alpha-level 0.05) could be inferred as proof or probability statements about the truth or falsehood of the null hypothesis (H-0) and the alternative hypothesis (H-1).Results: Almost all participants reported having a university degree, and among statisticians/epidemiologist, most reported having a university degree in statistics and were working professionally with statistics. Overall, 9.4% of statisticians/epidemiologist and 24.0% of doctoral students responded that the statistically significant finding proved that H-0 is not true, and 73.4% of statisticians/epidemiologists and 53.3% of doctoral students responded that the statistically significant finding indicated that H(0 )is improbable. Corresponding numbers about inferences about the alternative hypothesis (H-1) were 12.0% and 6.2% about proving H-1 being true and 62.7 and 62.5% for the conclusion that H-1 is probable. Correct inferences to both questions, which is that a statistically significant finding cannot be inferred as either proof or a measure of a hypothesis' probability, were given by 10.7% of doctoral students and 12.5% of statisticians/epidemiologists.Conclusions: Misinterpretation of P-values and statistically significant test results persists also among persons who have substantial statistical education and who work professionally with statistics.

Fatty Acid Proportions in Plasma Cholesterol Esters and Phospholipids Are Positively Correlated in Various Swedish Populations
- 2017
-
In: Journal of Nutrition. - : Elsevier BV. - 0022-3166 .- 1541-6100. ; 147:11, s. 2118-2125

Journal article (peer-reviewed)abstract
- Background: Fatty acid (FA) proportions in cholesterol esters (CEs) and plasma phospholipids are widely used as dietary biomarkers. Information on how proportions in these fractions correlate could have implications for interpretation and use of FA biomarkers in observational and interventional studies. Objective: We investigated correlations between FA proportions in CEs and phospholipids in free-living individuals and assessed how diet-induced alterations of FA proportions correlate between fractions. Methods: Spearman's rank correlation coefficients (rs) between FA proportions (percentage of total FAs) in circulating CEs and phospholipids were calculated separately in 8 individual study populations including Swedish females and males (N = 2052; age range: 11-84 y), and pooled by inverse-variance weighted meta-analysis. In addition, study populations were stratified by age, sex, body mass index (BMI; in kg/m(2)), and diabetes status, and strata-specific rs were pooled by meta-analysis. In 2 randomized trials (N = 79) in which dietary saturated FAs were isocalorically replaced with unsaturated FAs, treatment-wise calculations of rs were conducted between FA changes in CEs and phospholipids. Results: Overall, FA proportions in CEs and phospholipids correlated well and especially strongly for polyunsaturated FAs (PUFAs), with pooled rs (95% CIs) ranging from 0.74 (0.72, 0.76) for a-linolenic acid to 0.92 (0.91, 0.93) for eicosapentaenoic acid. Weak correlations (pooled rs <0.4) were observed only for palmitic acid and stearic acid, with pooled rs (95% CIs): 0.29 (0.24, 0.33) and 0.30 (0.25, 0.34), respectively. Overall, correlations were not affected by age, sex, BMI, or diabetes status. Strong correlations (r(s) >= 0.6) between diet-induced FA changes in CEs and phospholipids were observed for most PUFAs. Conclusions: Proportions of most FAs in CEs and phospholipids ranked individuals similarly, suggesting that FA proportions in these fractions can be used interchangeably in populations of diverse age, sex, body composition, and diabetes status. Caution is advised, however, when comparing results from studies assessing palmitic acid or stearic acid in different lipid fractions.

Journal article (peer-reviewed)abstract
- AimsDose-dependent effects of β-blockers on survival and cardiovascular outcomes after myocardial infarction (MI) are not well understood. We investigated the long-term risk of cardiovascular events in patients with different doses of β-blockers after MI.Methods and resultsThis was a nationwide observational study linking morbidity, mortality, socioeconomic, and medication data from Swedish national registries. Between 2006 and 2015, 97 575 unique patients with first-time MI were included. In total, 33 126 (33.9%) patients were discharged with ≥50% of the target β-blocker dose and 64 449 (66.1%) patients with <50% of the target β-blocker dose used in previous randomized trials. The primary composite endpoint was re-infarction or all-cause death within 1 year from discharge. Multivariable adjusted 1-year follow-up estimates using mixed effects Cox regression [HR (95% CI)] showed that patients treated with ≥50% of the target dose had a similar risk of the composite endpoint [1.03 (0.99–1.08)] and a somewhat higher risk when stroke, atrial fibrillation, or heart failure hospitalization were added to the composite endpoint [1.08 (1.04–1.12)], compared with patients on <50% of the target β-blocker dose. Results remained similar up to 5 years of follow-up and consistent across relevant patient subgroups, including patients who developed heart failure during the index hospitalization.ConclusionsIn contrast to doses of β-blockers used in previous trials, ≥50% of the target β-blocker dose was not associated with superior cardiovascular outcomes up to 5 years as compared with <50% of the target dose. Contemporary randomized clinical trials are needed to clarify the optimal dose of β-blockers after MI.

Education immigration and income as risk factors for hemoglobin a1c >70 mmol/mol when diagnosed with type 2 diabetes or latent autoimmune diabetes in adult : A population-based cohort study
- 2017
-
In: BMJ Open Diabetes Research and Care. - : BMJ. - 2052-4897. ; 5:1
-
Journal article (peer-reviewed)abstract
- Objectives The aim of this research is to study education, income and immigration as risk factors for high hemoglobin A1c (HbA1c >70 mmol/mol (8.6%)) when diagnosed with type 2 diabetes (T2D) or latent autoimmune diabetes in the adult (LADA). Research design and methods Patients were included from the All New Diabetics in Scania study (2008-2013). Level of education, disposable income and immigration year were retrieved from the longitudinal integrated database for labour market research (LISA) register compiled by Statistics Sweden. Logistic regression models were used to estimate ORs for HbA1c >70 mmol/mol (8.6%) at diagnosis. Results A total of 3794 patients with incident T2D (n=3 525) or LADA (n=269) were included. Patients with T2D with a low (≤9 years) or medium (10-12 years) levels of education were more likely to have high HbA1c at diagnosis compared with patients with T2D with a high (>12 years) level of education (OR 1.34, 95% CI 1.08 to1.66, OR 1.26, 95% CI 1.03 to 1.54). Low-income patients with T2D (<60% of median) were more likely to have high HbA1c at diagnosis compared with high-income patients withT2D (>150% of median) (OR 1.35, 95% CI 1.02 to 1.79). Conclusions Patients with lower levels of education or low income and are more likely to have HbA1c is >70 mmol/ mol (8.6%) when diagnosed with T2D. An understanding of how socioeconomic position influences the clinical presentation at diagnosis may facilitate screening programs designed to target populations at risk for delayed diagnosis.

Effectiveness by gender and age of renin-angiotensin system blockade in heart failure-A national register-based cohort study
- 2020
-
In: Pharmacoepidemiology and Drug Safety. - : Wiley. - 1053-8569 .- 1099-1557. ; 29:5, s. 518-529
-
Journal article (peer-reviewed)abstract
- Purpose: Investigate effectiveness by gender and age and equity implications of treatment with renin‐angiotensin system blockade (RASb) in heart failure (HF) patients.Methods: In this population‐based register study, we used inpatient data from 2006 to 2010 for patients age 20 years or older with no HF hospitalisation for minimum of 1 year before an index hospitalisation. A wash‐out period for RASb of 6 months preceding admission was used.Hospital data were linked with drug dispensation data and cause of death data. The associations between time‐dependent RASb exposure and all‐cause death and HF death, respectively, were examined by Cox regression models. Interactions by gender and age were also investigated on the multiplicative and additive scales.Results: Thirty thousand seven hundred twenty‐one patients were analysed. Fifty‐one percent were women. Median age was 83. Fifty‐three percent of women and 64% of men received RASb after the index hospitalisation. Younger patients were more likely to receive RASb than older ones. One‐year mortality was 28%. RASb was associated with an overall hazard ratio (HR) for all‐cause death of 0.72 (95% confidence interval 0.69‐0.75), and an HR of 0.85 (0.77‐0.93) for HF death. Interaction analyses showed HRs for all‐cause death associated with RASb between 0.12 (0.10‐0.13) in the youngest, and 0.80 (0.76‐0.84) in the oldest patients.Conclusions: RASb appeared effective for women and men and for patients of all ages in this hospitalised HF cohort. No gender difference in effectiveness was found. RASb exposure was low overall, indicating a need for improved adherence to treatment guidelines. Treatment with RASb may be inequitable for women and older patients.

The effect of group-based cognitive behavioral therapy on inflammatory biomarkers in patients with coronary disease : results from the SUPRIM-trial
- 2018
-
In: Upsala Journal of Medical Sciences, Supplement. - : Uppsala Medical Society. - 0300-9726 .- 0300-9734 .- 2000-1967. ; 123:3, s. 167-173
-
Journal article (peer-reviewed)abstract
- Background: The Secondary Prevention in Uppsala Primary Healthcare Project (SUPRIM) is a prospective randomized controlled trial of a group-based cognitive behavioral therapy (CBT) stress management program for coronary heart disease (CHD) patients. The intervention reduced the risk of fatal or non-fatal first recurrent cardiovascular (CV) events. The aim of the present study was to analyze if the positive effects of the CBT program on clinical outcomes could have been mediated by changes in biomarkers for inflammation.Methods: Altogether 362 patients with CHD were randomly assigned to intervention or usual care. The inflammatory biomarkers (VCAM-1, TNF-R1, TNF-R2, PTX3, and hs-CRP) were serially assessed at five time points every six months from study start until 24 months later, and analyzed with linear mixed models.Results: Baseline levels of the inflammatory markers were near normal, indicating a stable phase. The group-based CBT stress management program did not significantly affect the levels of inflammatory biomarkers in patients with CHD. Three out of five (VCAM-1, TNF-R2, and PTX3) inflammatory biomarkers showed a slight increase over time in both study groups, and all were positively associated with age.Conclusion: Group-based CBT stress management did not affect biomarkers for inflammation in patients with CHD. It is therefore unlikely that inflammatory processes including these biomarkers were mediating the effect the CBT program had on the reduction in CV events. The close to normal baseline levels of the biomarkers and the lack of elevated psychological distress symptoms indicate a possible floor effect which may have influenced the results.Keywords: Biomarkers, CBT, CHD, inflammation, stress management

Association between HbA(1c) and peripheral neuropathy in a 10-year follow-up study of people with normal glucose tolerance, impaired glucose tolerance and Type 2 diabetes
- 2017

Journal article (peer-reviewed)abstract
- Aims To explore the association between HbA(1c) and sural nerve function in a group of people with normal glucose tolerance, impaired glucose tolerance or Type 2 diabetes. Methods We conducted a 10-year follow-up study in 87 out of an original 119 participants. At study commencement (2004), 64 men and 55 women (mean age 61.1 years) with normal glucose tolerance (n=39), impaired glucose tolerance (n=29), or Type 2 diabetes (n=51) were enrolled. At the 2014 follow-up (men, n=46, women, n=41; mean age 71.1 years), 36, nine and 42 participants in the normal glucose tolerance, impaired glucose tolerance and Type 2 diabetes categories, respectively, were re-tested. Biometric data and blood samples were collected, with an electrophysiological examination performed on both occasions. Results At follow-up, we measured the amplitude of the sural nerve in 74 of the 87 participants. The mean amplitude had decreased from 10.9 V (2004) to 7.0 mu V (2014; Pamp;lt;0.001). A 1% increase in HbA(1c) was associated with a similar to 1% average decrease in the amplitude of the sural nerve, irrespective of group classification. Crude and adjusted estimates ranged from -0.84 (95% CI -1.32, -0.37) to -1.25 (95% CI -2.31, -0.18). Although the mean conduction velocity of those measured at both occasions (n=73) decreased from 47.6 m/s to 45.8 m/s (P=0.009), any association with HbA(1c) level was weak. Results were robust with regard to potential confounders and missing data. Conclusions Our data suggest an association between sural nerve amplitude and HbA(1c) at all levels of HbA(1c). Decreased amplitude was more pronounced than was diminished conduction velocity, supporting the notion that axonal degeneration is an earlier and more prominent effect of hyperglycaemia than demyelination.

Vibrotactile perception on the sole of the foot in an older group of people with normal glucose tolerance and type 2 diabetes
- 2020

In: SAGE Open Medicine. - : Sage Publications. - 2050-3121. ; 8, s. 1-9
-
Journal article (peer-reviewed)abstract
- Objectives: To evaluate vibrotactile sense in an older group of people with normal glucose tolerance and type 2 diabetes relative to other sensory tests.Methods: Vibration perception thresholds on the sole of the foot (Multifrequency vibrametry and Biothesiometer) were compared to the results from evaluation of touch (monofilament), electrophysiology (sural nerve) and thermal sensation (Thermotest®).Results: Vibration perception and temperature thresholds, as well as sural nerve function, differed between normal glucose tolerance and type 2 diabetes. Measuring vibration perception thresholds at lower frequencies with multifrequency vibrametry versus biothesiometer provided correlations similar to sural nerve amplitude. Temperature thresholds correlated with vibration perception thresholds and sural nerve function. Monofilaments revealed pathology in only a few participants with type 2 diabetes.Conclusions: In an older group of people, vibration perception thresholds show a correlation similar to sural nerve amplitude on tactile and non-tactile surfaces. Measuring a vibration perception threshold on a tactile surface in type 2 diabetes provides no clear advantage over measuring it on the medial malleolus. In older type 2 diabetes subjects, both large and small diameter nerve fibers are affected.

Estimating the variance of a propensity score matching estimator: A new look at right heart catheterisation data
- 2014
-
Reports (other academic/artistic)abstract
- This study considers the implementation of a variance estimator when estimating the asymptotic variance of a propensity score matching estimator for the average treatment effect. We investigate the role of smoothing parameters in the variance estimator and propose using local linear estimation. Simulations demonstrate that large gains can be made in terms of mean squared error by properly selecting smoothing parameters and that local linear estimation may lead to a more efficient estimator of the asymptotic variance. The choice of smoothing parameters in the variance estimator is shown to be crucial when evaluating the effect of right heart catheterisation, i.e. we show either a negative effect on survival or no significant effect depending on the choice of smoothing parameters.

- This study considers variance estimation when estimating the asymptotic variance of a propensity score matching estimator for the average treatment effect. We investigate the role of smoothing parameters in a variance estimator based on matching. We also study the properties of estimators using local linear estimation. Simulations demonstrate that large gains can be made in terms of mean squared error, bias and coverage rate by properly selecting smoothing parameters. Alternatively, a residual-based local linear estimator could be used as an estimator of the asymptotic variance. The variance estimators are implemented in analysis to evaluate the effect of right heart catheterisation.

Some Aspects of Propensity Score-based Estimators for Causal Inference
- 2014
-
Doctoral thesis (other academic/artistic)abstract
- This thesis consists of four papers that are related to commonly used propensity score-based estimators for average causal effects.The first paper starts with the observation that researchers often have access to data containing lots of covariates that are correlated. We therefore study the effect of correlation on the asymptotic variance of an inverse probability weighting and a matching estimator. Under the assumptions of normally distributed covariates, constant causal effect, and potential outcomes and a logit that are linear in the parameters we show that the correlation influences the asymptotic efficiency of the estimators differently, both with regard to direction and magnitude. Further, the strength of the confounding towards the outcome and the treatment plays an important role.The second paper extends the first paper in that the estimators are studied under the more realistic setting of using the estimated propensity score. We also relax several assumptions made in the first paper, and include the doubly robust estimator. Again, the results show that the correlation may increase or decrease the variances of the estimators, but we also observe that several aspects influence how correlation affects the variance of the estimators, such as the choice of estimator, the strength of the confounding towards the outcome and the treatment, and whether constant or non-constant causal effect is present.The third paper concerns estimation of the asymptotic variance of a propensity score matching estimator. Simulations show that large gains can be made for the mean squared error by properly selecting smoothing parameters of the variance estimator and that a residual-based local linear estimator may be a more efficient estimator for the asymptotic variance. The specification of the variance estimator is shown to be crucial when evaluating the effect of right heart catheterisation, i.e. we show either a negative effect on survival or no significant effect depending on the choice of smoothing parameters. In the fourth paper, we provide an analytic expression for the covariance matrix of logistic regression with normally distributed regressors. This paper is related to the other papers in that logistic regression is commonly used to estimate the propensity score.

Inter- and intra-rater reliability for measurement of range of motion in joints included in three hypermobility assessment methods
- 2018
-
In: BMC Musculoskeletal Disorders. - : BMC. - 1471-2474. ; 19
-
Journal article (peer-reviewed)abstract
- Background: Comparisons across studies of generalized joint hypermobility are often difficult since there are several classification methods and methodological differences in the performance exist. The Beighton score is most commonly used and has been tested for inter- and intra-rater reliability. The Contompasis score and the Hospital del Mar criteria have not yet been evaluated for reliability. The aim of this study was to investigate the inter- and intra-rater reliability for measurements of range of motion in joints included in these three hypermobility assessment methods using a structured protocol.Methods: The study was planned in accordance with guidelines for reporting reliability studies. Healthy adults were consecutively recruited (49 for inter-and 29 for intra-rater assessments). Intra-class correlations, two-way random effects model, (ICC 2.1) with 95% confidence intervals, standard error of measurement, percentage of agreement, Cohen's Kappa () and prevalence-adjusted bias-adjusted kappa were calculated for single-joint measured in degrees and for total scores.Results: The inter- and intra-rater reliability in total scores were ICC 2.1: 0.72-0.82 and 0.76-0.86 and for single-joint measurements in degrees 0.44-0.91 and 0.44-0.90, respectively. The difference between ratings was within 5 degrees in all but one joint. Standard error of measurement ranged from 1.0 to 6.9 degrees. The inter- and intra-rater reliability for prevalence of positive hypermobility findings the Cohen's for total scores were 0.54-0.78 and 0.27-0.78 and in single joints 0.21-1.00 and 0.19-1.00, respectively. The prevalence- and bias adjusted Cohen's , increased all but two values.Conclusions: Following a structured protocol, the inter- and intra-rater reliability was good-to-excellent for total scores and in all but two single joints, measured in degrees. The inter- and intra-rater reliability for prevalence of positive hypermobility findings was fair-to-almost perfect for total scores and slight-to-almost-perfect in single joints.By using a structured protocol, we attempted to standardize the assessment of range of motion in clinical and in research settings. This standardization could be helpful in the first part of the process of standardizing the tests thus avoiding that assessment of GJH is based on chance.

Validity of the self-reported five-part questionnaire as an assessment of generalized joint hypermobility in early pregnancy
- 2020
-
In: BMC Musculoskeletal Disorders. - : Springer Nature. - 1471-2474. ; 21:1
-
Journal article (peer-reviewed)abstract
- BackgroundThe assessment of generalized joint hypermobility is difficult due to differences in classification methods and in the performance of joint mobility assessment. The primary aim was to evaluate the validity of the self-reported five-part questionnaire, 5PQ, for identifying generalized joint hypermobility using the Beighton score as reference test. The secondary aim was to describe how joint angles measured in degrees included in the Beighton score varied in different cut-off levels in the self-reported 5PQ and the Beighton score.MethodsA cross-sectional validity study with a total of 301 women in early pregnancy, mean age of 31 years, were included in the study. The participants answered the self-reported 5PQ before the joint angles were measured. To standardize the joint mobility measurement, a structural protocol was used. The sensitivity, specificity, receiver operating characteristic curve, area under curve, positive- and negative predictive value, positive likelihood ratio and Spearman’s rank correlation between the self-reported 5PQ ≥ 2 and the Beighton score ≥ 5 were used as main outcome measures in the validity analyses. Joint angles, measured in degrees, were calculated with means in relation to different cut-off levels.ResultsThere was moderate correlation between the self-reported 5PQ and the Beighton score. The highest combined sensitivity, 84.1%, as well as specificity, 61.9%, was on 5PQ cut-off level ≥ 2, with a 38% false-positive rate, a moderate area under curve, a low positive predictive value and likelihood ratio, and a high negative predictive value. The odds of a self-reported 5PQ, cut-off level ≥ 2, among women with generalized joint hypermobility, Beighton ≥5, was low indicating a low post-test probability. The mean for all joint angles measured in degrees increased with increased cut-off levels, both in the Beighton score and in the self-reported 5PQ. However, there was a significant variation for each cut-off level.ConclusionsThere is uncertainty in identifying generalized joint hypermobility in young women using the self-reported 5PQ with a cut-off level of ≥2 when the Beighton score ≥ 5 is used as the reference test. The strength of the self-reported 5PQ is to rule-out women without generalized joint hypermobility.

Is it possible to influence ability, willingness and understanding among nursing home care staff to implement nutritional guidelines? : A comparison of a facilitated and an educational strategy
- 2021
-
In: International Journal of Older People Nursing. - : John Wiley & Sons. - 1748-3735 .- 1748-3743. ; 16:3
-
Journal article (peer-reviewed)abstract
- Background: Translating nutrition knowledge into care practice is challenging since multiple factors can affect the implementation process. This study examined the impact of two implementation strategies, that is external facilitation (EF) and educational outreach visits (EOVs), on the organisational context and individual factors when implementing nutritional guidelines in a nursing home (NH) setting.Methods: The EF strategy was a one-year, multifaceted (including support, guidance, a practice audit and feedback) intervention given to four NH units. The EOV strategy was a three-hour lecture about the nutritional guidelines given to four other NH units. Both strategies were directed at selected NH teams, consisting of a unit manager, a nurse and 5-10 care staff. A questionnaire was distributed, before and after the interventions, to evaluate the prerequisites for the staff to use the guidelines. Three conditions were used to examine the organisational context and the individual factors: the staff's ability and willingness to implement the nutritional guidelines and their understanding of them. Confirmatory factor analysis and structural equation models were used for the data analysis.Results: The results indicated that on average, there was a significant increase in the staff's ability to implement the nutritional guidelines in the EF group. The staff exposed to the EF strategy experienced better resources to implement the guidelines in terms of time, tools and support from leadership and a clearer assignment of responsibility regarding nutrition procedures. There was no change in staff's willingness and understanding of the guidelines in the EF group. On average, no significant changes were observed for the staff's ability, willingness or understanding in the EOV group.Conclusions: A long-term, active and flexible implementation strategy (i.e. EF) affected the care staff's ability to implement the nutritional guidelines in an NH setting. No such impact was observed for the more passive, educational approach (i.e. EOV).

How does social support shape the association between depressive symptoms and labour market participation : a four-way decomposition
- 2022
-
In: European Journal of Public Health. - : Oxford University Press. - 1101-1262 .- 1464-360X. ; 32:1, s. 8-13

Journal article (peer-reviewed)abstract
- BACKGROUND: Little is known about factors that may explain the association between depressive symptoms and poor labour market participation (LMP). The aim of this study is to examine the mediation and interaction effects of social support on the association between depressive symptoms and LMP.METHODS: Data were used from 985 participants (91% of the initial cohort) of the Northern Swedish Cohort, a longitudinal study of Swedish participants followed from adolescence throughout adulthood. Depressive symptoms were measured at age 16, social support at age 21 and LMP from age 30 to 43. Poor LMP was defined as being unemployed for a total of 6 months or more between the ages of 30 and 43. A four-way decomposition approach was applied to identify direct, mediation and interaction effects, together and separately.RESULTS: Both depressive symptoms during adolescence and social support at young adulthood were associated with poor LMP [odds ratio (OR) = 1.70, 95% confidence interval (CI) 1.17-2.47 and OR = 2.56, 95% CI 1.78-3.68 respectively]. The association between depressive symptoms and poor LMP was partially mediated by a lack of social support. No interaction effect of a lack of social support was found.CONCLUSION: The results suggest that depressive symptoms influence not only later LMP but also the intermediary level of social support, and in turn influencing later LMP. Recommendations for public health are to detect and treat depressive symptoms at an early stage and to focus on the development of social skills, facilitating the increased availability of social support, thereby improving future LMP.

- BACKGROUND: The Heart School is a standard component of cardiac rehabilitation after myocardial infarction in Sweden. The group-based educational intervention aims to improve modifiable risks, in turn reducing subsequent morbidity and mortality. However, an evaluation with respect to mortality is lacking.AIMS: Using linked population registries, we estimated the association of attending Heart School with both all-cause and cardiovascular mortality, two and five years after admission for first-time myocardial infarction.METHODS: Patients with first-time myocardial infarction (<75 years) were identified as consecutively registered in the nationwide heart registry, SWEDEHEART (2006-2015), with >99% complete follow-up in the Causes of Death registry for outcome events. Of 192,059 myocardial infarction admissions, 47,907 unique patients with first-time myocardial infarction surviving to the first cardiac rehabilitation visit constituted the study population. The exposure was attending Heart School at the first cardiac rehabilitation visit 6-10 weeks post-myocardial infarction. Data on socioeconomic status was acquired from Statistics Sweden. After multiple imputation, propensity score matching was performed. The association of exposure with mortality was estimated with Cox regression and survival curves.RESULTS: After matching, attending Heart School was associated (hazard ratio (95% confidence interval)) with a markedly lower risk of both all-cause (two-year hazard ratio = 0.53 (0.44-0.64); five-year hazard ratio = 0.62 (0.55-0.69)) and cardiovascular (0.50 (0.38-0.65); 0.57 (0.47-0.69)) mortality. The results were robust in several sensitivity analyses.CONCLUSIONS: Attending Heart School during cardiac rehabilitation is associated with almost halved all-cause and cardiovascular mortality after first-time myocardial infarction. The result warrants further investigation through adequately powered randomised trials.

- Background: Cancer in a child is highly distressing and some parents are at increased risk for developing posttraumatic stress symptoms (PTSS). However, the interdependence of PTSS in parental dyads has rarely been accounted for. The aim was to explore the dyadic relationship of PTSS in parents of children diagnosed with cancer.Material and methods: The sample includes 150 parents (75 dyads) of 75 children diagnosed with cancer in Sweden during 2002–2004, with follow-up until one year after end of treatment. Data on PTSS from six assessments were included. The first three assessments were carried out during treatment and the remaining after end of treatment. Actor-partner interdependence models were estimated using a structural equation modeling approach to explore the dyadic relationship of PTSS. Actor effects refer to intra-individual dependency over time, and partner effects refer to inter-individual dependency over time, i.e., how much an individual’s symptom levels are affected by their partner’s symptom levels at the previous assessment.Results: Results show both actor and partner effects during the child’s treatment. Only an actor effect remained following end of treatment where level of PTSS at one assessment was associated with the level of PTSS at the subsequent assessment. The association between mothers’ and fathers’ PTSS did not remain after end of treatment.Conclusions: Parents appear to react as an interdependent emotional system during the child’s treatment but this effect disappears after end of treatment. Results suggest psychological interventions for parents during the child’s cancer treatment should also be sensitive to and address the influence that distress in one partner may have on the other.
