Abstract

Abstract: Objectives: This study examined three competing mechanisms in the link between educational attainment and health among young adults: (a) a health behaviour mechanism; (b) a psychosocial stressor mechanism; and (c) a health insurance mechanism. The central research question was the pervasiveness and specificity of these mechanisms in the link between low educational attainment and health outcomes during young adulthood. Study design: A prospective longitudinal study was conducted with 808 men and women followed to age 33 years in the USA. Methods: Health outcomes included major depressive disorder, obesity, chronic health conditions, and self-rated health. The focal predictor was educational attainment at age 21. The roles of the health behaviour mechanism (heavy episodic drinking, cigarette smoking, and meeting physical activity guidelines), the psychosocial stressor mechanism (stressful life events, perceived financial stress, and lack of control at work), and having health insurance (either through their employer or union or via family members) in the link between education and varying health outcomes were assessed using path analyses. Results: Lack of health insurance emerged as a statistically significant explanatory factor underlying the association of education with depression and self-rated health. Health behaviours, specifically smoking and physical activity, were statistically significant intervening factors for obesity and self-rated health. Conclusions: The processes linking educational attainment to health inequalities begin unfolding during young adulthood. The salience of different mechanisms is specific to a health outcome rather than pervasive across multiple health outcomes. Public health policies with a broad spectrum of components, particularly focussing on smoking, physical activity, and lack of health insurance, are recommended to promote educational equalities in multiple health outcomes among young adults. Highlights: The processes of educational health inequalities are already unfolding during young adulthood. Different explanatory mechanisms were evident for different health measures. Having a health insurance accounted for the link between education and depression. Health behaviours explained educational disparities in self-perceived health status. Psychosocial stressors did not emerge as a statistically significant explanatory factor.
