    • The aim of this study was to explore the association between oral health and obesity. The study was conducted in the spring of 2007 as a postal survey of all inhabitants born in 1942 and living in the two Swedish counties of Örebro and Östergötland. This questionnaire survey has been conducted every five years since 1992 but has been updated continually with additional questions and for the sweep used here, height and weight data were collected. A total of 8,313 individuals received the questionnaire and 6,078 of those responded (73,1%).The outcome variable oral health was measured using one global question and four detailed questions representing different aspects of oral health. The independent variable Body Mass Index (BMI) was calculated using self-reported height and weight. A difference in oral health between various BMI groups was found. The difference was both statistically significant and of clinical importance, particularly among the group with severe obesity who reported poorer self-perceived chewing capacity lower satisfaction with dental appearance, increased mouth dryness and fewer teeth and lower overall satisfaction with oral health. In view of the increased risk of poor oral health demonstrated in this study for those with severe obesity, it may be of value to increase cooperation between dental care and primary health care for these patients.

  • Laterality, hand control and scholastic performance : a British birth cohort study
  • 2012
  • Ingår i: BMJ Open. - London, United Kingdom : BMJ Publishing Group Ltd. - 2044-6055 .- 2044-6055. ; 2:2, s. e000314-

    • Objectives: To use simple measures of laterality and hand control that can identify a greater risk of poorer scholastic ability, potentially signalling suboptimal hemispheric lateralisation.Design: Analysis of material from a birth cohort study.Setting: Members of the National Child Development Study, a British birth cohort study following people born in 1958.Participants: 10 612 children who undertook tests at age 11 years.Primary outcome measures: Teacher-administered tests of non-verbal general ability, verbal general ability, reading comprehension and mathematics. Results Linear regression produced associations (and 95% CIs) with tests of verbal general ability, non-verbal general ability, reading comprehension and mathematics scores for the lowest third (compared with highest) of a left-hand control test involving picking up matches of −1.21 (−1.73 to −0.68; p<0.001), −0.72 (−1.14 to −0.29; p=0.001), −0.70 (−1.06 to −0.35; p<0.001) and −1.32 (−1.90 to −0.73; p<0.001). Among those in the lowest third of the right-hand control test score, mixed-handedness compared with right-handedness was associated with poorer scholastic performance, with regression coefficients (and 95% CIs; p values) of 1.90 (−3.01 to −0.80; p=0.001), −1.25 (−2.15 to −0.35; p=0.007), −1.28 (2.04 to −0.53; p=0.001) and −1.33 (−2.53 to −0.13; p=0.030). The estimates are for a point change in the scholastic test scores, after adjustment for sex, left-hand motor function and social class. Statistically significant associations with mixed-handedness were only observed for the lowest third of right-hand motor function.Conclusions Measures involving poorer left-hand motor function may represent useful markers of reduced cognitive function possibly reflecting suboptimal hemispheric lateralisation. Crude measures of laterality such as reported non-right-handedness may be more useful for research when combined with measures of motor function.

  • Change in health status in COPD : a seven-year follow-up cohort study
  • 2016
  • Ingår i: NPD Bulletin. - : Nature Publishing Group. - 1892-8110 .- 2055-1010. ; 26
  • Tidskriftsartikel (refereegranskat)abstract
    • Health status is a prognostic factor included in the assessment of chronic obstructive pulmonary disease (COPD). The aim of our study was to examine the associations of clinical factors with change in health status over a 7-year follow-up period. In 2005, 970 randomly selected primary and secondary care patients with a COPD diagnosis completed questionnaires including the Clinical COPD Questionnaire (CCQ); and in 2012, 413 completed the CCQ questionnaire again. Linear regression used difference in mean total CCQ score between 2005 and 2012 as the dependent variable. Independent variables were CCQ score at baseline 2005, sex, age, educational level, body mass index (BMI), smoking status, heart disease, diabetes, depression, number of exacerbations in the previous 6 months, dyspnoea (modified Medical Research Council (mMRC)). Health status worsened from mean total CCQ (s.d.) 2.03 (1.26) in 2005 to 2.16 (1.37) in 2012 (P=0.011). In linear regression with adjustment for baseline CCQ; older age, lower education, higher mMRC and BMI below 25 kg/m(2) at baseline were associated with worsened health status in 2012. When sex, age and all statistically significant measures were included simultaneously in the analysis of the main study group, higher mMRC and BMI below 25 kg/m(2) were were associated with deteriorated health status (P<0.0001). A higher level of dyspnoea and lower weight were associated with worse health status in COPD. Strategies for decreasing dyspnoea and awareness of the possible increased risk of worsening disease in under- and normal-weight COPD patients are clinically important.

  • Clinical COPD questionnaire score (CCQ) and mortality
  • 2012
  • Ingår i: The International Journal of Chronic Obstructive Pulmonary Disease. - Auckland, New Zealand : Dove Medical Press. - 1176-9106 .- 1178-2005. ; 7, s. 833-842
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: The Clinical COPD Questionnaire (CCQ) measures health status and can be used to assess health-related quality of life (HRQL). We investigated whether CCQ is also associated with mortality.Methods: Some 1111 Swedish primary and secondary care chronic obstructive pulmonary disease (COPD) patients were randomly selected. Information from questionnaires and medical record review were obtained in 970 patients. The Swedish Board of Health and Welfare provided mortality data. Cox regression estimated survival, with adjustment for age, sex, heart disease, and lung function (for a subset with spirometry data, n = 530). Age and sex-standardized mortality ratios were calculated.Results: Over 5 years, 220 patients (22.7%) died. Mortality risk was higher for mean CCQ ≥ 3 (37.8% died) compared with mean CCQ < 1 (11.4%), producing an adjusted hazard ratio (HR) (and 95% confidence interval [CI]) of 3.13 (1.98 to 4.95). After further adjustment for 1 second forced expiratory volume (expressed as percent of the European Community for Steel and Coal reference values ), the association remained (HR 2.94 [1.42 to 6.10]). The mortality risk was higher than in the general population, with standardized mortality ratio (and 95% CI) of 1.87 (1.18 to 2.80) with CCQ < 1, increasing to 6.05 (4.94 to 7.44) with CCQ ≥ 3.Conclusion: CCQ is predictive of mortality in COPD patients. As HRQL and mortality are both important clinical endpoints, CCQ could be used to target interventions.

  • The dyspnoea, obstruction, smoking, exacerbation (dose) index is predictive of mortality in COPD
  • 2012
  • Ingår i: Primary Care Respiratory Journal. - Sutton Coldfield, UK : The Primary Care Respiratory Society UK. - 1471-4418 .- 1475-1534. ; 21:3, s. 295-301
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The Dyspnoea, Obstruction, Smoking, Exacerbation (DOSE) index was designed to assess disease severity and for the clinical management of chronic obstructive pulmonary disease (COPD), but has not been evaluated as a prognostic instrument for mortality in a population including primary care patients.Aims: The aim of this study was to investigate the associations of the DOSE index with mortality in primary and secondary care COPD patients.Methods: Information was collected from 1,111 COPD patients aged 34-75 years randomly selected from 70 Swedish primary and secondary care centres. Data were obtained using patient questionnaires and record review and the Swedish Board of Health and Welfare provided mortality data. The study population included 562 patients with data on all DOSE index components. The DOSE index was calculated using the MRC dyspnoea scale, forced expiratory volume in 1 second (FEV1) as percentage of predicted (FEV1%pred), smoking status, and exacerbation rate. The exacerbation rate over 6 months prior to record review was used to estimate the annual rate. Cox regression analyses estimated survival with adjustment for age, sex, and heart disease.Results: Over 5 years, 116 patients (20.6%) died. Mortality was higher in patients with DOSE index >4 (42.4%) than for lower scores (11.0%) (p<0.0001). Compared with a DOSE index score of 0-3, the hazard ratio for mortality was 3.48 (95% CI 2.32 to 5.22) for a score of 4-5, and was 8.00 (95% CI 4.67 to 13.7) for a score of 6-7.Conclusions: The DOSE index is associated with mortality in COPD patients in primary and secondary care and can be used to assess prognosis in addition to other clinically relevant issues.

  • The underreporting of hepatocellular carcinoma to the Cancer Register and a log-linear model to estimate a more correct incidence
  • 2017
  • Ingår i: Hepatology. - Hoboken, USA : John Wiley & Sons. - 0270-9139 .- 1527-3350. ; 65:3, s. 885-892
  • Tidskriftsartikel (refereegranskat)abstract
    • The Cancer Register (CR) in Sweden has reported that the incidence of primary liver cancer (PLC) has slowly declined over the last decades. Even though all cancers, irrespective of diagnostic method, should be reported to the CR, the PLC incidence may not reflect the true rate. Improved diagnostic tools have enabled diagnosis of hepatocellular carcinoma (HCC) based on non-invasive methods without histological verification, possibly associated with missed cancer-reports or misclassification in the CR. Our objective was to study the completeness and assess the underreporting of PLC to the CR, and to produce a more accurate estimate based on three registers. The CR, the Cause of Death and the Patient Register were investigated. Differences and overlap were examined, the incidence was estimated by merging data from the registers, and the number reported to none of the registers was estimated using a log-linear capture-recapture model. The results show that 98% of the PLCs reported to the CR were histologically verified; 80% were HCC and 20% intrahepatic cholangiocarcinoma. Unspecified liver cancer decreased over time and constituted <10% of all reported liver cancers. The CR may underestimate the liver cancer incidence by 37% - 45%, primarily due to missed cancer-reports. The estimated annual number of liver cancers increased over time, but the standardized incidence was stable around 11 per 100,000. Hepatitis C associated liver cancer increased and constituted 20% in 2010.Conclusion: There was an underreporting of PLC diagnosed by non-invasive methods. The incidence was considerably higher than estimated by the CR, with a stable incidence over time. Reporting needs to improve and combining registers is recommended when studying incidence.

  • Gestational diabetes mellitus and later cardiovascular disease : a Swedish population based case-control study
  • 2014
  • Ingår i: British Journal of Obstetrics and Gynecology. - : Wiley-Blackwell. - 1470-0328 .- 1471-0528. ; 121:12, s. 1530-1536

    • Objective: To identify if gestational diabetes mellitus (GDM) is a clinically useful marker of future cardiovascular disease (CVD) risk and if GDM combined with other risks (smoking, hypertension or body mass) identifies high-risk groups.Design: Population-based matched case-control study.Setting: National Swedish register data from 1991 to 2008.Population: A total of 2639 women with a cardiovascular event and matched controls.Methods: Conditional logistic regression examined associations with CVD before and after adjustment for conventional risk factors and confounders. Effect modification for the association of GDM with CVD by body mass index (BMI), smoking and chronic hypertension was assessed by stratification and interaction testing. Adjustment for diabetes post-pregnancy evaluated its mediating role.Main outcome measures: Inpatient diagnoses or causes of death identifying ischemic heart disease, ischemic stroke, atherosclerosis or peripheral vascular disease.Results: The adjusted odds ratios (and 95% confidence intervals) for the association of CVD with GDM are 1.51 (1.07-2.14), 2.23 (2.01-2.48) for smoking, 1.98 (1.71-2.29) for obesity and 5.10 (3.18-8.18) for chronic hypertension. In stratified analysis the association of CVD with GDM was only seen among women with BMI 25, with an odds ratio of 2.39 (1.39-4.10), but only women with a BMI <30 accounted for this increased risk. Adjustment for post-pregnancy diabetes attenuated it somewhat to 1.99 (1.13-3.52).Conclusions: In the absence of other recognised cardiovascular risk factors, such as smoking, obesity or chronic hypertension, GDM is a useful marker of raised CVD risk among women with BMI between 25 and 29.

  • Mind and body exercises (MBE), prescribed antidepressant medication, physical exercise and depressive symptoms – a longitudinal study
  • 2020
  • Ingår i: Journal of Affective Disorders. - : Elsevier. - 0165-0327 .- 1573-2517. ; 265, s. 185-192
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: Earlier studies show that participation in mind and body exercises (MBE) is cross-sectionally associated with high levels of depressive symptoms and antidepressants. This study investigates the longitudinal interrelationship between depressive symptoms, MBE and antidepressants.Methods: 3269 men and 4318 women aged 24–74 years participated in the Swedish Longitudinal Occupational Survey of Health (SLOSH). Measures of MBE practice and depressive symptoms were drawn from the SLOSH questionnaire, data on prescription drugs were obtained from the Swedish Prescribed Drug Register. Structural Equation Modeling (SEM) was used to analyze temporal relationships.Results: Both MBE practice and antidepressants in 2012 was associated with higher levels of depressive symptoms two years later. Depressive symptoms in turn were associated with higher levels of later MBE practice and antidepressants. These relationships seemed to be explained by confounding by indication and were of higher magnitude for antidepressants than for MBE.Conclusion: Overall, SEM analysis shows that MBE and antidepressant treatment were both bi-directionally associated with depressive symptoms over time. Part of the explanation is likely to be confounding by indication: those with symptoms of depression more likely to undertake treatment, and MBE alone may be more common among those with less severe depression. The results clarify some of our findings from earlier studies and give some important, new information on what people are doing to manage depressive symptoms on a societal level, regarding self-care, medication, and the combination of both.

  • The use of ICD codes to identify IBD subtypes and phenotypes of the Montreal classification in the Swedish National Patient Register
  • 2020
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Taylor & Francis. - 0036-5521 .- 1502-7708. ; 55:4, s. 430-435
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Whether data on International Classification of Diseases (ICD)-codes from the Swedish National Patient Register (NPR) correctly correspond to subtypes of inflammatory bowel disease (IBD) and phenotypes of the Montreal classification scheme among patients with prevalent disease is unknown. Materials and methods: We obtained information on IBD subtypes and phenotypes from the medical records of 1403 patients with known IBD who underwent biological treatment at ten Swedish hospitals and retrieved information on their IBD-associated diagnostic codes from the NPR. We used previously described algorithms to define IBD subtypes and phenotypes. Finally, we compared these register-generated subtypes and phenotypes with the corresponding information from the medical records and calculated positive predictive values (PPV) with 95% confidence intervals. Results: Among patients with clinically confirmed disease and diagnostic listings of IBD in the NPR (N = 1401), the PPV was 97 (96-99)% for Crohn's disease, 98 (97-100)% for ulcerative colitis, and 8 (4-11)% for IBD-unclassified. The overall accuracy for age at diagnosis was 95% (when defined as A1, A2, or A3). Examining the validity of codes representing disease phenotype, the PPV was 36 (32-40)% for colonic Crohn's disease (L2), 61 (56-65)% for non-stricturing/non-penetrating Crohn's disease behaviour (B1) and 83 (78-87)% for perianal disease. Correspondingly, the PPV was 80 (71-89)% for proctitis (E1)/left-sided colitis (E2) in ulcerative colitis. Conclusions: Among people with known IBD, the NPR is a reliable source of data to classify most subtypes of prevalent IBD, even though misclassification commonly occurred in Crohn's disease location and behaviour and also among IBD-unclassified patients.

  • Atopic dermatitis, educational attainment and psychological functioning : a national cohort study
  • 2019
  • Ingår i: British Journal of Dermatology. - : Blackwell Science Ltd.. - 0007-0963 .- 1365-2133. ; 180:3, s. 559-564
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Atopic dermatitis (AD) might adversely affect academic performance, possibly through influences on psychological functioning such as stress resilience.OBJECTIVES: To investigate the association of atopic dermatitis with stress resilience, cognitive function and educational attainment.METHODS: We used data from a national cohort of men who underwent a military conscription examination at ages 17 to 20 years in Sweden between 1969 and 1976. All potential conscripts met a physician who assessed current or previous history of AD. Stress resilience was measured by a psychologist using a semi-structured interview. The conscription assessment included a written cognitive function test. Highest level of achieved education was obtained through record linkage.RESULTS: The study population included 234 715 men, 1 673 (0·7%) had an AD diagnosis. AD was associated with a greater risk of low stress resilience (adjusted relative risk ratio (RRR) 1·60; 95% confidence interval 1·38 to 1·86). AD was associated with higher cognitive function (b coefficient 0·15; 0·05 to 0·24) and higher educational level (RRR 1·29; 1·13 to 1·47) but adjustment for socioeconomic characteristics of the family of origin attenuated the magnitude of the associations and eliminated statistical significance (b coefficient 0·06; -0·03 to 0·15) and (RRR 1·16; 1·00 to 1·35).CONCLUSIONS: Swedish males with AD had lower stress resilience in late adolescence but did not have lower cognitive function or poorer educational attainment. The lower stress resilience associated with AD is consistent with an increased risk of possible long-term adverse health outcomes.
