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.
