- 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.

Contrasting Carbohydrate Quantity and Quality and the Effects on Plasma Saturated and Monounsaturated Fatty Acids in Healthy Adults : A Randomized Controlled Trial
- 2023

In: Journal of Nutrition. - : Elsevier. - 0022-3166 .- 1541-6100. ; 153:3, s. 683-690

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.

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.

Pelvic pain after childbirth : a longitudinal population study
- 2016

Journal article (peer-reviewed)abstract
- In this longitudinal population study, the aims were to study associations of mode of delivery with new onset of pelvic pain and changes in pelvic pain scores up to 7-18 months after childbirth. We included 20,248 participants enrolled in the Norwegian Mother and Child Cohort Study (1999-2008) without preexisting pelvic pain in pregnancy. Data were obtained by four self-administered questionnaires and linked to the Medical Birth Registry of Norway. A total of 4.5% of the women reported new onset of pelvic pain 0-3 months postpartum. Compared to unassisted vaginal delivery, operative vaginal delivery was associated with increased odds of pelvic pain (adjusted odds ratio 1.30; 95% confidence interval: 1.06-1.59). Planned and emergency cesarean deliveries were associated with reduced odds of pelvic pain (adjusted odds ratio 0.48; 95% confidence interval: 0.31-0.74 and adjusted odds ratio 0.65; 95% confidence interval: 0.49-0.87, respectively). Planned cesarean delivery, young maternal age, and low Symptom Checklist-8 scores were associated with low pelvic pain scores after childbirth. A history of pain was the only factor associated with increased pelvic pain scores over time (P=0.047). We conclude that new onset of pelvic pain after childbirth was not commonly reported, particularly following cesarean delivery. Overall, pelvic pain scores were rather low at all time points and women with a history of pain reported increased pelvic pain scores over time. Hence, clinicians should follow up women with pelvic pain after a difficult childbirth experience, particularly if they have a history of pain.

- 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.
