RESUMO
BACKGROUND AND AIMS: The incidence of cerebrovascular disease (CVD) is rising among young adults (<55 years). The risk for CVD starts to form in early childhood and is comprised of genetic and environmental risk factors. The aim of this study is to investigate the relationship between early family socioeconomic status (SES), inherited risk, and CVD until midlife. METHODS: In the Northern Finland Birth Cohort 1966 of 12,058 children, individuals were followed from gestational period up to 54 years. We used previously published early family SES clusters, based on latent class analysis of a wide set of prenatally collected variables. We investigated inherited risk with polygenic risk score (PRS) and parental CVDs during follow-up. The associations of the five distinct clusters, inherited risk, and consequent risk for various types of CVDs until middle age were analysed with Cox regression. All analyses were conducted first in the whole sample and then stratified by sex as is recommended in cardiovascular studies. RESULTS: During the follow-up of 586,943 person-years, 512 CVDs occurred. No clear association between SES clusters and CVD were found. Higher PRS associated with any CVD (HR per 1 SD increase 1.15; 95%CI 1.02-1.31), and ischemic CVD (HR 1.21; 1.05-1.40). We found no combined associations of early family SES and inherited risk for CVD. CONCLUSIONS: Inherited risk was associated with the risk for CVD in mid-life in Finnish population. We found no clear connection with early family SES and CVD. Being born to a specific SES group did not increase the effect of inherited risk.
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: The aim of the study is to investigate the role of chronotype for work engagement in middle age. METHODS: We used data from the Northern Finland Birth Cohort 1966 study ( N = 5341) to analyze associations of self-reported chronotype (morning, intermediate, and evening type) with work engagement and its dimensions (vigor, dedication, absorption). We conducted multivariate analyses of variance to examine whether work schedule or sleep problems moderate these associations. RESULTS: Evening types showed lower scores in work engagement and its dimensions than intermediate and morning types, even when work schedule and sleep problems were controlled. Sleep problems emphasized the chronotype-work engagement and chronotype-dedication linkages. CONCLUSIONS: Chronotype may play a role in employees' work engagement. In addition, sleep problems seem relevant in terms of chronotype-work engagement linkage.

INTRODUCTION: Urinary incontinence is a common ailment in women and is likely to affect their work ability. We investigated the associations between the different subtypes of urinary incontinence and several dimensions of perceived work ability in middle-aged general population. MATERIAL AND METHODS: Cross-sectional survey at age 46 among participants of the Northern Finland Birth Cohort 1966 study (n = 3706, response rate 72%). Urinary incontinence symptoms and several items of Work Ability Index were collected by postal questionnaire. Work ability was dichotomized as good or poor work ability in general, in relation to physical job demands, to diseases and own 2-year prospect of work ability. The associations between urinary incontinence and work ability measures were assessed using logistic regression models, with further adjustments for biological, behavioral and work-related factors as well as general health. RESULTS: The odds ratio (OR), from lowest to highest, for poor work ability were 1.4-fold among women with stress urinary incontinence (OR 1.37, 95% confidence interval [CI] 1.09-1.72), 2.5-fold with mixed urinary incontinence (OR 2.51, 95% CI 1.68-3.74) and 3.3-fold with urgency urinary incontinence (OR 3.34, 95% CI 1.95-5.70). We note that our results reflect work ability in a Nordic society. CONCLUSIONS: Especially urgency and mixed types of urinary incontinence are associated with poor work ability among middle-aged women.

Psychiatric illnesses can affect the social transitions of adolescence and young adulthood, such as completing education and entering working life and relationships. However, associations between earlier onset age and long-term outcomes among those with early-onset psychoses (EOP) are unclear, as are the long-term outcomes of EOP compared to non-psychotic disorders. We used national register data of the Northern Finland Birth Cohort 1986 to detect persons with EOP and other early-onset psychiatric disorders. The long-term clinical and work-family outcomes of persons with onset age before 18 years (n = 41 psychoses, n = 495 non-psychoses) or between 18-22 years (n = 61 psychoses, n = 377 non-psychoses) were compared. Individuals with the onset of psychosis between 18-22 years had significantly more unfavourable long-term outcomes when compared to those with psychosis onset before 18 years. Persons with psychosis onset before the age of 18 years had similar outcomes to those with non-psychotic psychiatric disorder onset before 18 years regarding educational level, marital status, having children, and substance use disorders. Individuals with EOP were more often on a disability pension compared to those with other early-onset mental disorders. Adjusting for sex, educational level and substance use only slightly diluted these results. Unexpectedly, later onset age of EOP was associated with worse outcomes. Those with psychosis onset between 18-22 years of age are in a critical period, which underlines the importance of investing on interventions in this age group. Further studies on the effect of the onset age on later outcomes in EOP are needed.
RESUMO
BACKGROUND: The Determinants of Implementation Behavior Questionnaire (DIBQ) measures facilitators or barriers of healthcare professionals' implementation behaviors based on the current implementation research on practice and policy. The DIBQ covers 18 domains of the Theoretical Domains Framework and consists of 93 items. A previously tailored version (DIBQ-t) covering 10 domains and 28 items focuses on implementing best-practice low back pain care. AIM: To tailor a shortened version of DIBQ to multiprofessional rehabilitation context with cross-cultural adaptation to Finnish language. DESIGN: A two-round Delphi study. SETTING: National-level online survey. POPULATION: Purposively recruited experts in multiprofessional rehabilitation (N.=25). METHODS: Cross-cultural translation of DIBQ to Finnish was followed by a two-round Delphi survey involving diverse experts in rehabilitation (physicians, physiotherapists, occupational therapists, psychologists, nursing scientists, social scientists). In total, 25 experts in Round 1, and 21 in Round 2 evaluated the importance of DIBQ items in changing professionals' implementation behavior by rating on a 5-point Likert Scale (1 = Strongly Disagree, 5 = Strongly Agree) of including each item in the final scale. Consensus to include an item was defined as a mean score of ≥4 by ≥75% of Delphi participants. Open comments were analyzed using inductive content analysis. Items with agreement of ≤74% were either directly excluded or reconsidered and modified depending on qualitative judgements, amended with experts' suggestions. After completing an analogous second-round, a comparison with DIBQ-t was performed. Lastly, the relevance of each item was indexed using content validity index on item-level (I-CVI) and scale-level (S-CVI/Ave). RESULTS: After Round 1, 17 items were included and 48 excluded by consensus whereas 28 items were reconsidered, and 20 items added for Round 2. The open comments were categorized as: 1) "modifying"; 2) "supportive"; and 3) "critical". After Round 2, consensus was reached regarding all items, to include 21 items. After comparison with DIBQ-t, the final multiprofessional DIBQ (DIBQ-mp) covers 11 TDF domains and 21 items with I-CVIs of ≥0.78 and S-CVI/Ave of 0.93. CONCLUSIONS: A Delphi study condensed a DIBQ-mp with excellent content validity for multiprofessional rehabilitation context. CLINICAL REHABILITATION IMPACT: A potential tool for evaluating determinants in implementing evidence-based multiprofessional rehabilitation interventions.

Sleep has been shown to affect economic outcomes, including wages. The mechanisms by which sleep affects wages remain unclear. We examine the relationship between chronotype - morning larks, evening owls - and wages at mid-age. We propose a novel model relating chronotype to wages in consideration of human, social, and health capital constructs. Empirically, we explore the effects of chronotype mediated through life course choices, such as work experience, trust, and health behaviour. The data come from the 46-year-old follow-up study of the Northern Finland Birth Cohort (1966) and from registers of the Finnish Tax Administration. We find evening chronotype to have a significant indirect negative effect on wages, which occurs through accumulating less work experience and through poor health outcomes. The effect is largest for male workers, with a total indirect effect on average wages of - 4%. We also provide evidence that chronotype has a long-term association with wages between 29 and 50 years of age. We conclude that evening-type workers are less suited to typical working hours and accumulate less human, social and health capital which in turn negatively affects their wages. Our findings are of great socio-economic importance because evening chronotypes make up a significant part of the population.

BACKGROUND: The Örebro Musculoskeletal Pain Screening Questionnaire (ÖMPSQ) was developed to identify psychological and functioning-related risk factors among individuals with musculoskeletal pain at risk of work disability. This study aimed to examine whether the short version of the ÖMPSQ (ÖMPSQ-SF) can be used for this purpose, using registry-based outcomes. METHODS: The ÖMPSQ-SF was completed by the members of the Northern Finland Birth Cohort 1966 at the age of 46 years (baseline). These data were enriched with national registers, including information on sick leaves and disability pensions (indicators of work disability). The associations between the ÖMPSQ-SF categories (low-, medium- and high risk) and work disability over a 2-year follow-up were analysed using negative binomial regression and binary logistic regression models. We made adjustments for sex, baseline education level, weight status and smoking. RESULTS: Overall, 4063 participants provided full data. Of these, 90% belonged to the low-risk, 7% to the medium-risk and 3% to the high-risk group. Compared to the low-risk group, the high-risk group had a 7.5 [Wald 95% confidence interval (CI) 6.2-9.0] times higher number of sick leave days and 16.1 (95% CI 7.1-36.8) times higher odds of disability pension after adjustments in the 2-year follow-up. CONCLUSIONS: : Our study suggests that the ÖMPSQ-SF could be used for predicting registry-based work disability at midlife. Those allocated to the high-risk group seemed to have a particularly great need of early interventions to support their work ability.

BACKGROUND: The fact that a complex relationship exists between alexithymia and body mass index (BMI) is well established, but the underlying mechanisms remain poorly understood. Here, we explore the relationship between alexithymia and depressive symptoms in relation to adiposity measures, including the direct and indirect effect of alexithymia and depressive symptoms on obesity over a 15-year time-period, in the Northern Finland Birth Cohort 1966 (NFBC1966). METHODS: The study included individuals from the Northern Finland Birth Cohort 1966 (NFBC1966) who had available data for adiposity measures (body mass index and waist-to-hip ratio), alexithymia (measured by the 20-Item Toronto Alexithymia Scale: TAS-20), depressive symptoms (measured by the 13-item depression subscale of Hopkins Symptom Checklist: HSCL-13) at age of 31 years (n = 4773) and 46 years (n = 4431). Pearson's (r) correlation, and multiple linear regression were used to investigate the relationships between alexithymia, depressive symptoms, and adiposity measures. The potential mediating role of depressive symptoms was examined via Hayes' procedure (PROCESS). RESULTS: Positive correlations were confirmed between adiposity measures (BMI and WHR) and the TAS-20 score (and its subscale), but not between obesity and HSCL-13 score. The strongest correlation was between the DIF (difficulty identifying feelings) subscale of the TAS-20 and HSCL-13 at both time points (31 y: r(3013) = 0.41, p < 0.01, 46 y: r(3013) = 0.43, p < 0.01). Depressive symptoms completely (z = 2.55 (±0.00003), p = 0.01) and partly (z = 2.16 (±0.0001), p = 0.03) mediated the alexithymia-obesity relationship over the 15-year time-period. LIMITATIONS: Other psychological and environmental factors such as interoception, dietary intake and physical activities may also play a role as a potential mediating factor in alexithymia-obesity relationship. CONCLUSIONS: Our findings provide additional insights of theoretical framework of depressive symptoms mediation effect in the relationship between alexithymia and obesity. Alexithymia and depression should, therefore, be considered in the design of future clinical obesity research.

PURPOSE: Psychoses are associated with poor labour market attachment, but few studies have compared schizophrenia (SZ) and other psychoses (OP). Moreover, studies on long-term employment trajectories over individuals' working life courses are lacking. We compared 30 year employment trajectory patterns in a general population sample among individuals with SZ, OP, and those with no psychosis (NP). METHODS: Utilising the Northern Finland Birth Cohort 1966, we collected survey data on employment from ages 16 to 45 and detected individuals with register-based history of SZ (n = 62), OP (n = 87), or NP (n = 6464) until age 46. Through gender-specific latent class analyses on annual employment roles, we identified traditional, highly educated, self-employed, delayed and floundering employment trajectories with distinct socioeconomic characteristics. We addressed attrition by conducting weighted analyses. RESULTS: Floundering trajectories were common among individuals with SZ (79% of men, 73% of women) and OP (52% of men, 51% of women). In NP, a traditional employee trajectory was most common in men (31%), and a highly educated trajectory in women (28%). A history of psychosis was associated with heightened odds ratios (ORs; 95% confidence intervals (CIs)) for floundering trajectories in both men (SZ: 32.9 (13.3-81.4); OP: 7.4 (4.0-13.9)) and women (SZ: 9.9 (4.6-21.5); OP: 3.9 (2.1-7.1)) compared to NP. Weighted analyses produced similar results. CONCLUSION: Most individuals with SZ or OP have floundering employee trajectories reflecting an elevated risk of unemployment and part-time work until midlife. These results indicate the importance of improving labour market attachment during the early phases of psychoses.

OBJECTIVE: The aim of the study is to evaluate how glucose metabolism in midlife is related to preceding 30-year-long employment trajectories. METHODS: In the Northern Finland Birth Cohort 1966, we compared glucose metabolism at 46 to employment trajectories (previously defined for men and women and named as high-educated, traditional, self-employed, delayed, and floundering; n = 6399). RESULTS: Compared with individuals in high-educated trajectories, odds ratios for type 2 diabetes (T2D, 95% confidence interval) in traditional and floundering trajectories in men were 1.65 (1.02-2.68) and 2.42 (1.38-4.23) and in women 1.89 (1.04-3.43) and 2.60 (1.46-4.62), respectively. In self-employed trajectory in women, odds ratios for prediabetes and T2D were 1.66 (1.09-2.51) and 2.47 (1.21-5.04). CONCLUSIONS: The highest risks for T2D in midlife were associated after traditional and floundering trajectories in men and women and after self-employment trajectory in women.

Occupation-related stress and work characteristics are possible determinants of social inequalities in epigenetic aging but have been little investigated. Here, we investigate the association of several work characteristics with epigenetic age acceleration (AA) biomarkers. The study population included employed and unemployed men and women (n = 631) from the UK Understanding Society study. We evaluated the association of employment and work characteristics related to job type, job stability; job schedule; autonomy and influence at work; occupational physical activity; and feelings regarding the job with four epigenetic age acceleration biomarkers (Hannum, Horvath, PhenoAge, GrimAge) and pace of aging (DunedinPoAm, DunedinPACE). We fitted linear regression models, unadjusted and adjusted for established risk factors, and found the following associations for unemployment (years of acceleration): HorvathAA (1.51, 95% CI 0.08, 2.95), GrimAgeAA (1.53, 95% CI 0.16, 2.90) and 3.21 years for PhenoAA (95% CI 0.89, 5.33). Job insecurity increased PhenoAA (1.83, 95% CI 0.003, 3.67), while working at night was associated with an increase of 2.12 years in GrimAgeAA (95% CI 0.69, 3.55). We found effects of unemployment to be stronger in men and effects of night shift work to be stronger in women. These results provide evidence of associations between unemployment with accelerated ageing and suggest that insecure employment and night work may also increase age acceleration. Our findings have implications for policies relating to current changes in working conditions and highlight the utility of biological age biomarkers in studies in younger populations without long-term health information.

BACKGROUND: Severe health events may lead to reduced income among survivors. Importantly, individuals' risks for both severe health events and for lower income are shaped by early life course. Our aim was to consider early-life factors in determining lost individual income after stroke, heart attack and cancer between ages 18 and 50. METHODS: A population-based Northern Finland Birth Cohort 1966 (N = 12 058) was used. Early-life factors were collected since mid-pregnancy until age 16 years and used to match all persons with stroke, heart attack, or cancer (n = 995) with four controls. Registered annual individual income development 15 years before and after the event was compared between cases and propensity score matched controls using time-to-event mixed models, stratified for sex. RESULTS: Compared to controls, a new decreasing income trend emerged among women after stroke (logarithmic income per time -0.54; 95% CI -0.88 to -0.20), whereas men getting stroke showed declining earnings already by the time of the event, further declining after stroke (-1.00, -1.37 to -0.63). Getting heart attack was associated with a new declining trend both in women (-0.68; -1.28 to -0.09) and men (-0.69, -1.05 to -0.32). Income declined also among control men (-0.24, -0.34 to -0.14), who had higher income but were less educated than control women. CONCLUSIONS: Stroke and heart attack but not cancer have exogenous deleterious effects on individual economy, independently of early-life factors. The effects accelerate by time. Negative income trend in control men shows that severe health events do not explain all decrease in income.

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.

OBJECTIVE: To examine the role of physical activity (PA) and sedentary behavior (SED) for work engagement. METHODS: We used data from Northern Finland Birth Cohort 1966 Study ( n = 3046 to 4356) to analyze self-reported weekly leisure-time physical activity (LTPA), daily leisure-time sitting time (LTST) and work engagement. PA and SED 24-hour were also measured with accelerometer for 14 days. The data were analyzed using linear regression analyses. RESULTS: High self-reported LTPA and sports participation were associated with higher work engagement and its subdimensions. High self-reported ST was associated with lower work engagement, vigor, and absorption. Accelerometer-measured light PA was associated with higher work engagement and vigor, and accelerometermeasured steps were linked to higher vigor. Accelerometer-measured SED was associated with lower work engagement, vigor, and dedication. CONCLUSIONS: Self-reported and accelerometer-measured PA and SED may play a role in people's work engagement.

Recent evidence indicates consistent association of low socioeconomic status with epigenetic age acceleration, measured from DNA methylation. As work characteristics and job stressors are crucial components of socioeconomic status, we investigated their association with various measures of epigenetic age acceleration. The study population included employed and unemployed men and women (n=604) from the Northern Finland Birth Cohort 1966. We investigated the association of job strain, effort-reward imbalance and work characteristics with five biomarkers of epigenetic aging (Hannum, Horvath, PhenoAge, GrimAge, and DunedinPoAm). Our results indicate few significant associations between work stress indicators and epigenetic age acceleration, limited to a range of ±2 years, and smoking recording the highest effect on GrimAge age acceleration biomarker between current and no smokers (median difference 4.73 years (IQR 1.18, 8.41). PhenoAgeAA was associated with job strain active work (ß=-1.301 95%CI -2.391, -0.212), slowing aging of less than 1.5 years, and working as white-collar slowed aging six months (GrimAgeAA ß=-0.683, 95%CI -1.264, -0.102) when compared to blue collars. Association was found for working for more than 40 hours per week that increased the aging over 1.5 years, (HorvathAA ß =2.058 95%CI 0.517,3.599, HannumAA ß=1.567, 95%CI 0.415,2.719). The pattern of associations was different between women and men and some of the estimated effects are inconsistent with current literature. Our results provide the first evidence of association of work conditions with epigenetic aging biomarkers. However, further epidemiological research is needed to fully understand how work-related stress affects epigenetic age acceleration in men and women in different societies.

Family's socioeconomic profile collected prenatally is known to predict offspring mortality during early life, but it remains unclear whether it has the potential to predict offspring mortality until later life. In this study, 12,063 individuals belonging to the Northern Finland Birth Cohort 1966 were followed up from mid-pregnancy for 52 years (570,000 person years). Five distinct socioeconomic profiles were identified by latent class analysis based on mother's marital status, education, and occupation; father's occupation; number of family members; location of residence, room count, and utilities; and family's wealth. The classes were highest status families (15.4% of the population), small families (22.1%), larger families (15.4%), average wealth families (23.4%), and rural families (23.3%). Their associations to offspring mortality, via linkage to national offspring death records, were analysed by Cox regression, stratified by sex and age groups (0-19, 20-38 and 40-52 years). In total, mortality was 9.2% among male and 5.0% among female offspring. Risk for midlife mortality was higher among male offspring from larger families (hazard ratio 2.19, 95% confidence interval 1.32-3.63), average wealth families (1.66, 1.02-2.73) and rural families (1.63, 1.00-2.68), relative to offspring from highest status families. It seems that family's socioeconomic profile constructed prenatally has predictive value for midlife mortality among male offspring. Premature mortality of men and women seem to be two distinct phenomena with differing underlying factors as socioeconomic profile was not associated with mortality among female offspring.

Background: Multisite pain is commonly chronic and often lacks its initial role as a potential tissue damage signal. Chronic pain among working-age individuals is a risk for disability and imposes a major burden on health care systems and society. As effective treatments for chronic pain are largely lacking, better identification of the factors associated with pain over working years is needed. Methods: Members of the Northern Finland Birth Cohort 1966 participated in data collection at the ages of 31 (n = 4,028) and 46 (n = 3,429). Using these two time points, we performed a multivariable analysis of the association of socioeconomic, occupational, psychological and lifestyle factors (i.e., low education, living alone, low household income, unemployment, occupational physical exposures [hard physical labor, leaning forward, back twisting, constant moving, lifting loads of ≥ 1 kg], physical inactivity, regular smoking, regular drinking, overweight, and psychiatric symptoms) with the number of musculoskeletal pain sites (i.e., upper extremity, lower extremity, lower back, and the neck-shoulder region; totalling 0-4 pain sites). The data were analyzed using generalized estimating equations. Results: At the age of 31, multisite pain was reported by 72.5% of men and 78.6% of women. At the age of 46, the prevalence of multisite pain was 75.7% among men and 82.7% among women. Among men, the number of pain sites was positively associated with age (rate ratio 1.05, 95% confidence interval 1.01-1.08), low household income (1.05, 1.01-1.08), unemployment (1.13, 1.06-1.19), any occupational exposure (1.17, 1.12-1.22), regular smoking (1.06, 1.02-1.11), and psychiatric symptoms (1.21, 1.17-1.26). Among women, the number of pain sites was positively associated with age (1.06, 1.04-1.10), unemployment (1.10, 1.05-1.15), any occupational exposure (1.10, 1.06-1.13), regular smoking (1.06, 1.02-1.10), overweight (1.08, 1.05-1.11), and psychiatric symptoms (1.19, 1.15-1.22); living alone was negatively associated with the number of pain sites (0.95, 0.91-0.99). Conclusion: Of the studied predictors, psychiatric symptoms, occupational physical exposures and unemployment were most strongly associated with multisite pain among both sexes. The results of this study deepen the understanding of the underlying factors of and comorbidities behind multisite pain, and help develop pain relief and rehabilitation strategies for working-age individuals with multisite pain.

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.
