- Aims: Musculoskeletal pain is a major health problem, especially in women, and is partially determined by psychosocial factors. The aim of the present study was to investigate whether gender inequality in the couple relationship was related to musculoskeletal pain. Methods: Participants (n=721; 364 women and 357 men) were all individuals living in a couple relationship in the Northern Swedish Cohort, a 26-year Swedish cohort study. Self-administered questionnaire data at age 42 years comprised perceived gender inequality in the couple relationship and musculoskeletal pain (in three locations, summarised into one score and median-split), concurrent demographic factors, psychological distress, and previous musculoskeletal pain at age 30 years. Associations were examined using logistic regression. Results: Gender inequality was positively associated with symptoms of musculoskeletal pain in the total sample, remaining significant after addition of possible confounders and of previous musculoskeletal pain. Separate adjustment for concurrent psychological distress attenuated the association but not below significance. The association was present and of comparable strength in both women and men. Conclusions: Gender inequality in the couple relationship might contribute to the experience of musculoskeletal pain in both women and men. The results highlight the potential adverse bodily consequences of living in unequal relationships.

- Objective: We aimed to investigate the association between life-course exposure to snus and prevalence of the metabolic syndrome and its components in adulthood.Design and method: Tobacco habits at baseline (age 16) and three follow-ups (ages 21, 30 and 43) were assessed among 880 participants in a population-based cohort in Northern Sweden. Presence of the metabolic syndrome at age 43 was ascertained using the International Diabetes Federation criteria. Odds ratios and CIs for risk of the metabolic syndrome and its components by snus use at 16, 21, 30 and 43 years were calculated using logistic regression. Cumulative snus use was defined as number of life periods (1-4) with current snus use.Results: At age 43, 164 participants (18.6%) were current snus users. We found no association between exclusive snus use at the ages of 16, 21, 30 and 43 years and the metabolic syndrome at age 43 years. Snus use (among non-smokers) was associated with raised triglycerides and high blood pressure in crude analysis, but not in multivariable models. There was no association between cumulative snus use and risk of the metabolic syndrome. Cumulative snus use was associated with central obesity, raised triglycerides and impaired fasting glucose/diabetes mellitus type 2 in crude analyses, but not after adjustments.Conclusion: The health consequences of snus exposure from adolescence to mid-adulthood do not seem to include increased risk of the metabolic syndrome or its components. The cardio-metabolic risk of dual exposure to snus and cigarettes may warrant further attention.

- While the importance of social relations for health has been demonstrated in childhood, adolescence and adulthood, few studies have examined the prospective importance of peer relations for adult health. The aim of this study was to examine whether peer problems in the school setting in adolescence relates to the metabolic syndrome in middle-age. Participants came from the Northern Swedish Cohort, a 27-year cohort study of school leavers (effective n = 881, 82% of the original cohort). A score of peer problems was operationalized through form teachers' assessment of each student's isolation and popularity among school peers at age 16 years, and the metabolic syndrome was measured by clinical measures at age 43 according to established criteria. Additional information on health, health behaviors, achievement and social circumstances were collected from teacher interviews, school records, clinical measurements and self-administered questionnaires. Logistic regression was used as the main statistical method. Results showed a dose-response relationship between peer problems in adolescence and metabolic syndrome in middle-age, corresponding to 36% higher odds for the metabolic syndrome at age 43 for each SD higher peer problems score at age 16. The association remained significant after adjustment for health, health behaviors, school adjustment or family circumstances in adolescence, and for psychological distress, health behaviors or social circumstances in adulthood. In analyses stratified by sex, the results were significant only in women after adjustment for covariates. Peer problems were significantly related to all individual components of the metabolic syndrome. These results suggest that unsuccessful adaption to the school peer group can have enduring consequences for metabolic health.

- ABSTRACT: BACKGROUND: During the past two decades, the hypothesis of fetal origins of adult disease has received considerable attention. However, critique has also been raised regarding the failure to take the explanatory role of accumulation of other exposures into consideration, despite the wealth of evidence that social circumstances during the life course impact on health in adulthood. The aim of the present prospective cohort study was to examine the contributions of birth weight and life course exposures (cumulative socioeconomic disadvantage and adversity) to dyslipidemia and serum lipids in mid-adulthood. METHODS: A cohort (effective n = 824, 77%) was prospectively examined with respect to self-reported socioeconomic status as well as stressors (e.g., financial strain, low decision latitude, separation, death or illness of a close one, unemployment) at the ages of 16, 21, 30 and 43 years; summarized in cumulative socioeconomic disadvantage and cumulative adversity. Information on birth weight was collected from birth records. Participants were assessed for serum lipids (total cholesterol, low- and high-density lipoprotein cholesterol and triglycerides), apolipoproteins (A1 and B) and height and weight (for the calculation of body mass index, BMI) at age 43. Current health behavior (alcohol consumption, smoking and snuff use) was reported at age 43. RESULTS: Cumulative life course exposures were related to several outcomes; mainly explained by cumulative socioeconomic disadvantage in the total sample (independently of current health behaviors but attenuated by current BMI) and also by cumulative adversity in women (partly explained by current health behavior but not by BMI). Birth weight was related only to triglycerides in women, independently of life course exposures, health behaviors and BMI. No significant association of either exposure was observed in men. CONCLUSIONS: Social circumstances during the life course seem to be of greater importance than birth weight for dyslipidemia and serum lipid levels in adulthood.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundThe hypothesis of fetal origins of adult disease has during the last decades received interest as an explanation of chronic, e.g. cardiovascular, disease in adulthood stemming from fetal environmental conditions. Early programming and enduring dysregulations of the hypothalamic-pituitary-adrenal (HPA axis), with cortisol as its end product, has been proposed as a possible mechanism by which birth weight influence later health status. However, the fetal origin of the adult cortisol regulation has been insufficiently studied. The present study aims to examine if body size at birth is related to circadian cortisol levels at 43 years.MethodsParticipants were drawn from a prospective cohort study (n = 752, 74.5%). Salivary cortisol samples were collected at four times during one day at 43 years, and information on birth size was collected retrospectively from delivery records. Information on body mass during adolescence and adulthood and on health behavior, medication and medical conditions at 43 years was collected prospectively by questionnaire and examined as potential confounders. Participants born preterm or < 2500 g were excluded from the main analyses.ResultsAcross the normal spectrum, size at birth (birth weight and ponderal index) was positively related to total (area under the curve, AUC) and bedtime cortisol levels in the total sample. Results were more consistent in men than in women. Descriptively, participants born preterm or < 2500 g also seemed to display elevated evening and total cortisol levels. No associations were found for birth length or for the cortisol awakening response (CAR).ConclusionsThese results are contradictory to previously reported negative associations between birth weight and adult cortisol levels, and thus tentatively question the assumption that only low birth weight predicts future physiological dysregulations.

- PURPOSE: To assess whether body mass index (BMI), blood pressure, and socioeconomic status in adolescence and early adulthood are independently related to the metabolic syndrome in adult women and men. METHODS: We based our work on a Swedish prospective cohort study that recruited participants at 16 years of age (N = 1083 at age 16; 403 women and 429 men at age 43, 78% of those still alive [N = 1071]). Blood pressure (BP) and BMI were assessed when participants were 16 and 21 years of age. At age 43, the metabolic syndrome was defined according to the International Diabetes Federation guidelines. Socioeconomic status (SES) was operationalized by the participant (age 21 and 43) or parent's (age 16) occupational status. Information on smoking, snuff, alcohol, and inactivity was collected at age 43. RESULTS: In women, SES at age 16 was independently related to the risk of metabolic syndrome. In women and men, BMI at age 16 was related to metabolic syndrome but was attenuated by BMI at age 21, which was significant in the final model; in women systolic BP displayed similar patterns. CONCLUSIONS: Our data seem to suggest two independent life course pathways for metabolic syndrome: one metabolic pathway for both women and men operating through BMI (for women also systolic BP) in adolescence and early adulthood, and for women, an apparently independent pathway through adolescent socioeconomic disadvantage.

- Although the health risk of socioeconomic disadvantage over the life-course is fairly established, the mechanisms are less studied. One candidate pathway is long-term dysregulation of cortisol. This study assesses whether socioeconomic trajectories from adolescence to adulthood influences the regulation of cortisol in mid-adulthood, and further investigates the importance of adolescence as a critical period and of accumulation of socioeconomic disadvantage. Participants were drawn from a 27-year prospective cohort study (n = 732, 68% of the original cohort). Information on socioeconomic status (SES) was collected at the ages of 16 (based on parental occupation), 21, 30 and 43 (based on own occupation) years, and at 43 years participants collected one-day salivary cortisol samples at awakening, after 15 min, before lunch and at bedtime. We found that the cortisol awakening response (CAR) differed with respect to SES trajectory; those with stable low or early low/upwardly mobile SES tended to display higher CAR than those with early high/downwardly mobile, highly mobile or stable high trajectories. Further analyses revealed that early low SES was related to higher CAR, and in women low SES was related to lower bedtime cortisol, independently of later SES and potential confounders. We found no support for a linear effect of accumulation of socioeconomic disadvantage. In conclusion, our study gives support for an independent effect of low socioeconomic status early in life, on the regulation of cortisol in adulthood.

Residential Selection across the Life Course : Adolescent Contextual and Individual Determinants of Neighborhood Disadvantage in Mid-Adulthood
- 2013
-
Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 8:11, s. e80241-
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Numerous cross-sectional studies have examined neighborhood effects on health. Residential selection in adulthood has been stressed as an important cause of selection bias but has received little empirical attention, particularly its determinants from the earlier life course. The present study aims to examine whether neighborhood, family, school, health behaviors and health in adolescence are related to socioeconomic disadvantage of one's neighborhood of residence in adulthood. Methods: Based on the prospective Northern Swedish Cohort (analytical N = 971, 90.6% retention rate), information was collected at age 16 years concerning family circumstances, school adjustment, health behaviors and mental and physical health. Neighborhood register data was linked to the cohort and used to operationalize aggregated measures of neighborhood disadvantage (ND) at age 16 and 42. Data was analyzed with linear mixed models, with ND in adulthood regressed on adolescent predictors and neighborhood of residence in adolescence as the level-2 unit. Results: Neighborhood disadvantage in adulthood was clustered by neighborhood of residence in adolescence (ICC = 8.6%). The clustering was completely explained by ND in adolescence. Of the adolescent predictors, ND (b =.14 (95% credible interval =.07-.22)), final school marks (b =-.18 (-.26--.10)), socioeconomic disadvantage (b =.07 (.01-.14)), and, with borderline significance, school peer problems (b =-.07 (-.00-.13)), were independently related to adulthood ND in the final adjusted model. In sex-stratified analyses, the most important predictors were school marks (b =-.21 (-.32--.09)) in women, and neighborhood of residence (ICC = 15.5%) and ND (b =.20 (.09-.31)) in men. Conclusions: These findings show that factors from adolescence - which also may impact on adult health - could influence the neighborhood context in which one will live in adulthood. This indicates that residential selection bias in neighborhood effects on health research may have its sources in early life.

- BackgroundLittle is known about the theoretically assumed association between adversity exposure over the life course and allostatic load in adulthood.PurposeThis study aims to examine whether social and material adversity over the life course is related to allostatic load in mid-adulthood.MethodsA 27-year prospective Swedish cohort (N = 822; 77% response rate) reported exposure to social and material adversities at age 16, 21, 30 and 43 years. At age 43, allostatic load was operationalized based on 12 biological parameters.ResultsSocial adversity accumulated over the life course was related to allostatic load in both women and men, independently of cumulative socioeconomic disadvantage. Moreover, social adversity in adolescence (in women) and young adulthood (in men) was related to allostatic load, independently of cumulative socioeconomic disadvantage and also of later adversity exposure during adulthood.ConclusionExposure to adversities involving relational threats impacts on allostatic load in adulthood and operates according to life course models of cumulative risk and a sensitive period around the transition into adulthood.

Tidskriftsartikel (refereegranskat)abstract
- Background: Obesity and body mass in adulthood relate both to current and to childhood socio-economic status, particularly in women, but the underlying life course processes are not known. This study aims at examining whether the life course socio-economic status—body mass association in women and men is explained by the cumulative risk or adolescent sensitive period models whether associations are similar at different life course stages; and whether health behaviours explain the associations. Methods: A total of 476 women and 517 men participated in this 27-year prospective cohort study (participation rate 93%). Body mass index was assessed at the age of 16 and 43 years and self-reported at the age of 21 and 30 years. Information on socio-economic status by own or parental (age 16 years) occupation, smoking, snuff, alcohol, physical activity and diet was collected at each age. Results: In women, cumulative socio-economic status and socio-economic status in adolescence were related to body mass index at the age of 16, 21, 30 and 43 years and to the 27-year change in body mass, independently of health behaviours and for adolescent socio-economic status also of later socio-economic attainment. Associations were generally stronger for body mass at older age. In men, associations were mostly non-significant, although health behaviours contributed strongly to body mass. Conclusions: In women, both the sensitive period (in adolescence) and cumulative risk models explain the socio-economic–body mass link. Efforts to reduce the social inequality in body mass in women should be directed at the early life course, but focusing on unhealthy behaviours might not be a sufficient approach.
