RESUMO
OBJECTIVE: To study the association between an advanced climacteric status at 46 years of age and current perceived work ability, the consequent 2-year accumulation of disability and unemployment days, and the 7-year incidence of disability pensions. METHODS: Study participants (n = 2,661) were recruited from the Northern Finland Birth Cohort 1966 study's 46-year follow-up in 2012. The participants' perceived work ability was investigated using the Work Ability Score (0-7 = poor vs 8-10 = good), along with potential covariates. Data concerning their consequent disability days, unemployment days, and disability pensions were collected from national registers. The association between their climacteric status at age 46 years, work ability, and working life participation was assessed using regression models. RESULTS: The climacteric women were more often smokers and more often had a lower level of education. The odds ratio for poor perceived work ability was 1.41 (95% CI, 1.06-1.87), and the incidence rate ratios for disability and unemployment days during the 2-year follow-up were 1.09 (95% CI, 1.07-1.11) and 1.16 (95% CI, 1.14-1.18), respectively, for the climacteric women compared with the preclimacteric women in models adjusted for smoking and education. The 7-year hazard ratio for disability pensions was 1.72 (95% CI, 1.02-2.91) for the climacteric women. CONCLUSIONS: An earlier menopausal transition is associated with poorer perceived work ability, and it predicts lower recorded work participation and a higher disability pension rate in subsequent years.

Objective: Polycystic ovary syndrome (PCOS) presents with multiple comorbidities potentially affecting function. This was the first general population-based study to evaluate work ability, participation in working life, and disability retirement in middle-aged women with and without PCOS. Design: This is a cohort study. Methods: Women with PCOS (n = 280) and women without PCOS symptoms or diagnosis (n = 1573) were identified in the Northern Finland Birth Cohort in 1966 and were evaluated for self-rated work ability and potential confounders at age 46. Next, incidence rate ratios (IRRs) for disability and unemployment days were extracted from national registers during a prospective 2-year follow-up. Lastly, we assessed hazard ratios (HRs) for disability retirement between 16 and 52 years of age from national registers. Results: The women with PCOS reported poorer ability to work at age 46, especially due to poorer health. During the 2-year follow-up period, the affected women gained on average an additional month of disability and unemployment days, corresponding to an approximately 25% higher risk for both disability (IRR (95% CI): 1.25 (1.22-1.27)) and unemployment days (IRR (95% CI): 1.26 (1.23-1.28)) in models adjusted for health and socioeconomic factors. Lastly, we found a two-fold higher cumulative risk for disability retirement by age 52 compared to non-PCOS women (HR (95% CI): 1.98 (1.40-2.80)), which remained after adjusting for confounding factors (aHR (95% CI): 1.55 (1.01-2.38)). Conclusions: PCOS is associated with lower participation in working life already in midlife. Acknowledging PCOS-related multimorbidity, concerted efforts are needed to support sustainable careers for women with PCOS.

Data are insufficient on the protective effect of a farm environment in childhood regarding sensitization in middle age and new-onset sensitization in adulthood. A skin prick test (SPT) and questionnaire data from the Northern Finland Birth Cohort 1966 study (NFBC66) were used to investigate sensitization at age 46 years related to childhood living environment. A subpopulation of 3409 participants was analyzed to study factors related to new-onset sensitization between ages of 31 and 46 years. Data on complete SPTs were available for 5373 cohort members at age 46. Professional farming by parents (odds ratio (OR) 0.54; 95% confidence interval (CI) 0.43-0.68) and keeping of farm animals (OR 0.53; 95% CI 0.43-0.66) in infancy were associated with a lower risk of sensitization at age 46. Sensitization (OR 0.58; 95% CI 0.47-0.72) and polysensitization (OR 0.43; 95% CI 0.32-0.57) were less common in those who lived in a rural area in infancy compared to a city area. The childhood living environment had no effect on new-onset sensitization between ages 31 and 46. We conclude that living on a farm or in a rural environment in childhood had a protective effect on sensitization even in middle age, but these factors did not protect from new-onset sensitization in adults.

AIMS: To examine the association of physical activity (PA) and sedentary time (ST) with glucose metabolism according to waist circumference (WC) in older people. METHODS: A population-based sample of 702 individuals (aged 67-70 years) wore wrist-worn accelerometers for two weeks and underwent an oral glucose tolerance test. The associations between moderate-to-vigorous (MVPA) and light (LPA) PA, ST, and glucose metabolism across the tertiles of WC were analysed using general linear regression. RESULTS: Among highest WC tertile, LPA negatively associated with fasting insulin (ß = - 0.047, 95% CI - 0.082 to - 0.012), HOMA-IR (ß = - 0.098, 95% CI - 0.184 to - 0.012), and HOMA-ß (ß = - 3.367, CI - 6.570 to - 0.783). ST associated with 120 min glucose (ß = 0.140, CI 0.021 to 0.260). Among lowest WC tertile, MVPA negatively associated with 30 min insulin (ß = - 0.086, 95% CI - 0.168 to - 0.004) and 120 min insulin (ß = - 0.160, 95% CI - 0.257 to - 0.063) and positively associated with Matsuda index (ß = 0.076, 95% CI 0.014 to 0.139). Light PA negatively associated with 120 min insulin (ß = - 0.054, 95% CI - 0.104 to - 0.005). CONCLUSION: With the limitation of the cross-sectional study, reducing ST and increasing LPA may be beneficial for glucose metabolism among abdominally obese older adults. Lean older adults could benefit more from increasing MVPA.

INTRODUCTION: Endometriosis may cause a deterioration of daily functioning due to related symptoms such as pain, fatigue and psychological distress. Accordingly, endometriosis may jeopardize work ability, as suggested in mainly survey-based case-control studies, including clinically established cases at fertile age. This is the first general population-level study to evaluate how endometriosis is associated with (1) self-rated work ability and sick leave dates at age 46 years, (2) registered disability and unemployment days between age 46 and 48 and (3) lifelong emergence of registered disability retirement up to age 52. MATERIAL AND METHODS: Endometriosis case identification was based on the Care Register for Health Care and self-reported diagnosis from a population-based birth cohort, which covers 96% of children born in Northern Finland in 1966. A total of 348 women with endometriosis and 3487 women without endometriosis were identified. Questionnaire data on Work Ability Index Score was collected at age 46. Unemployment and disability days were determined from the Social Insurance Institution of Finland and the Finnish Center for Pensions registers. Finally, each individual's first-ever granted pension decision and diagnoses were collected until age 52 years. The associations between endometriosis and work ability were assessed using logistic regression models. RESULTS: Endometriosis was associated with poor work ability at age 46 (odds ratio [OR] 1.62, 95% confidence interval [CI] 1.06-2.47). Furthermore, the association between endometriosis and over 10 days of absenteeism was increased (OR 1.53; 95% CI 1.05-2.23). Between ages 46 and 48, women with endometriosis had 10 days more disability days (55.5 vs 45.5, p = 0.030) in comparison to women without endometriosis, but 20 days less unemployment days (40.6 vs 59.2 days, p = 0.013). There were no differences in early retirement between the study groups until age 52. CONCLUSIONS: Our study showed that endometriosis associates with poor work ability at age 46. Women with endometriosis have more disability days. However, their employment rate and risk of early retirement are comparable to those of women without endometriosis at late fertile age.

Studies on the longitudinal changes in sensitization to aeroallergens in adult populations are sparse. The aim was to evaluate changes in sensitization to aeroallergens [birch, timothy, cat and house dust mite (HDM)] in an unselected adult population aged from 31 to 46 years. Data were gathered from a cohort of adults (Northern Finland Birth Cohort 1966) who had been skin prick tested (SPT) with birch, timothy, cat and HDM allergens at the age of 31 years and at age 46 (n = 5484 and 5373 respectively). Data from both time points were available for 3409 participants, who made up the cohort of the longitudinal study. The overall prevalence of sensitization to any of the selected allergens was 30.3% (n = 1661) in 31-year-olds and 30.7% (n = 1649) in 46-year-olds. In general, men were more sensitized (P < 0.001) and also had more polysensitization (P < 0.001) compared to women. In longitudinal sub-population incidence of sensitization was 7.1%. Birch was the most prevalent new sensitizer, however, the difference was not statistically significant when compared to cat. We conclude that new sensitization, demonstrated by positive findings in SPT, can still occur in middle age and this should be taken into account when managing allergic manifestations in adults as sensitization can be considered the first step in developing clinical allergy.

BACKGROUND: The relevance of health-related behaviors to exclusion from the labor market in early adulthood remains poorly studied in relation to the magnitude of the problem. We explored whether adolescents' accumulated unhealthy behaviors and psychosocial problems are associated with later labor market exclusion, and whether multisite musculoskeletal pain (MMSP) impacts these relations. METHODS: We gathered questionnaire data on unhealthy behaviors and psychosocial problems and MMSP among adolescents aged 15 to 16 belonging to the Northern Finland Birth Cohort 1986. The findings were combined with registry data on unemployment, employment and permanent work disability during a five-year follow-up between the ages of 25 and 29 (n = 6692). In the statistical modeling we used education, family leave and socioeconomic status of childhood family as potential confounders, as well as latent class and logistic regression analyses. RESULTS: The Externalizing behavior cluster associated with over one year of unemployment (RR 1.64, CI 1.25-2.14) and permanent work disability (OR 2.49, CI 1.07-5.78) in the follow-up among the men. The Sedentary cluster also associated with over one year (RR 1.41, CI 1.13-1.75) and under one year of unemployment (RR 1.25, CI 1.02-1.52) and no employment days (RR 1.93, CI 1.26-2.95) among the men. Obese male participants were at risk of over one year of unemployment (RR 1.50, CI 1.08-2.09) and no employment days (RR 1.93, CI 1.07-3.50). Among the women, the Multiple risk behavior cluster related significantly to over one year of unemployment (RR 1.77, CI 1.37-2.28). MMSP had no influence on the associations. CONCLUSIONS: Unhealthy behavior patterns and psychosocial problems in adolescence have long-term consequences for exclusion from the labor market in early adulthood, especially among men. Simultaneously supporting psychological well-being and healthy behaviors in adolescence may reduce labor market inclusion difficulties in the early phase of working life.

OBJECTIVE: To evaluate how clinically measured glucose metabolism categories predict registered participation in working life. METHODS: In the 46-year follow-up of Northern Finland Birth Cohort 1966 (n=5328, 2342 men and 2986 women), we used oral glucose tolerance tests, surveys and glycated haemoglobin to determine glucose metabolism categorised as normal, pre-diabetes, screen-detected and previous type 2 diabetes (T2D). Consequent participation in working life during the 2-year follow-up period was measured as registered disability, unemployment and employment days, for which incidence rate ratios (IRRs) with 95% CIs were calculated using Poisson regression, adjusted for baseline employment and socioeconomic, health-related and behavioural factors. RESULTS: In comparison to normal glucose, all categories of impaired glucose metabolism were associated with poorer participation in working life in the unadjusted models. After adjustments, the risks (IRR (95% CI)) of disability days remained heightened by both screen-detected and previous T2D among men (1.3 (1.3 to 1.4) and 1.5 (1.4 to 1.5), respectively), whereas among women the risks were lowered (0.9 (0.8 to 0.9) and 0.9 (0.9 to 1.0), respectively). The risks of unemployment were consistently higher in all categories of impaired glucose metabolism, and were the highest among women with previous T2D (1.6 (1.5 to 1.6)). Correspondingly, the rates of total employment days were lower in relation to screen-detected T2D among men and women (5% and 6%, respectively), and previous T2D (6% and 3%). CONCLUSIONS: Overall, impaired glucose metabolism associated with deteriorated working life participation already in middle age. The high prevalence of impaired glucose metabolism emphasises the need for actions to support sustainable working careers.

BACKGROUND: Regular physical activity (PA) promotes health and decreases mortality. The positive relationship between PA and perceived health (PH) is well known. However, previous research in the field has often used self-reported PA measures. The aim of this population-based NFBC1966 birth cohort study was to assess the relationship between both self-reported and objectively measured PA and PH in midlife. METHODS: A sample group of 6384 participants (2878 men, 3506 women, response rate 62%) aged 46 completed a questionnaire on PH and health behaviors, including items on weekly leisure time physical activity (LTPA) and daily sitting time (ST). PH was dichotomized as good (very good or good) and other (fair, poor, or very poor). PA was measured with a wrist-worn Polar Active (Polar Electro, Finland) accelerometer for 14 days (n = 5481, 98%) and expressed as daily average time spent in moderate to vigorous intensity PA (MVPA). Odds ratios (OR) and 95% confidence intervals for good PH were calculated using binary logistic regression and adjusted for relevant demographic, socioeconomic, and health characteristics, and ST. RESULTS: The level of PA was positively associated with PH after adjustments with covariates and ST. There was a dose-response relationship across the PA quartiles according to the adjusted multivariable models. Self-reported LTPA was more strongly associated with good PH (OR from 1.72 to 4.33 compared to lowest PA quartile) than objectively measured PA (OR from 1.37 to 1.66 compared to lowest PA quartile). CONCLUSIONS: In this large population-based birth cohort study, we for the first time show a positive dose-response relationship of both self-reported and objectively measured PA to PH, the relationship being stronger for self-reported LTPA. Despite the cross-sectional design of this study, the results from this large sample suggest that both self-reported and objectively measured physical activity are strongly associated with PH, which is a predictor of morbidity and mortality, and regular PA should be encouraged in midlife.

BACKGROUND: Most studies on prolonging working careers have explored later career, while less is known about social and particularly health-related determinants of entry into labour market. We examined social and health-related factors from childhood and adolescence as predictors of age at entry into paid employment and early occupational class, and whether own education moderates these associations. METHODS: The Northern Finland Birth Cohort 1986 was followed from birth until the end of 2015. We included 8542 participants (52% male) who had had a minimum of 6-month employment that was defined by registered earning periods. As socioeconomic predictors, we examined low parental education at age 7 and low household income at age 16. Behaviour- and health-related factors at age 16 included smoking, alcohol use, physical inactivity, overweight, length of sleep and not having breakfast, while mental health problems included symptoms of anxiety and depression, attention problems and social problems. The analyses for significant predictors were further stratified by register-based level of completed own education by age 28-29 (low/high). RESULTS: After adjustments, low parental education, smoking and having been drunk were significant predictors of early entry into paid employment (≤18 vs. ≥24 years), especially among those who later obtained high education. Low parental education and smoking were predictors of low or non-specified (vs. high) occupational class in the first job. Mental health problems were not associated with either outcome. CONCLUSIONS: Socioeconomic background and unhealthy lifestyle contribute to early entry into the labour market and low occupational status in the first job.

AIMS: We explored whether registered unemployment is associated with impaired glucose metabolism in general population. METHODS: Based on Northern Finland Birth Cohort 1966 at 46 years, we analyzed the oral glucose tolerance tests of 1970 men and 2544 women in relation to their preceding three-year employment records in three categories of unemployment exposure: no (employed), low (≤1-year) and high exposure (>1-year). RESULTS: Among men, pre-diabetes was found in 19.2% of those with no unemployment, 23.0% with low and 27.0% with high exposure, the corresponding figures for screen-detected type 2 diabetes were 3.8%, 3.8% and 9.2% (p<0.01). Among women, analogous figures for pre-diabetes were 10.0%, 12.6% and 16.2% and for screen-detected type 2 diabetes 1.7%, 3.4% and 3.6% (p<0.01). Men with high exposure to unemployment had a higher risk for pre-diabetes (OR 1.61, CI 95% 1.03-2.51) and screen-detected type 2 diabetes (OR 2.58 95% CI 1.23-5.44) than employed men, after adjustment for education, smoking, alcohol intake, physical activity and body mass index. Among women, associations were attenuated in the adjusted models. CONCLUSIONS: High exposure to unemployment may predispose to type 2 diabetes in middle-aged men. For clinicians, awareness of the patient's unemployment status may be helpful in recognizing undiagnosed cases.
