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.

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.

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.

Objectives: Unemployment has been linked with poor health. We hypothesized that being unemployed is associated with disorders of glucose metabolism and performed a systematic review and meta-analysis of the literature to ascertain the relationship.

Methods: We searched the databases of Scopus, Medline Ovid and Web of Science for population-based original studies for past 20 years.

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.
