How Midlife Chronic Stress Combines with Stressful Life Events to Influence Later Life Mental and Physical Health for Husbands and Wives in Enduring Marriages.

To investigate how midlife chronic stress (40-50 years) and subsequent acute stressful events (50-65 years) influence husbands' and wives' later life mental and physical health (65+ years). Dyadic structural equation modeling was used with prospective data over 25 years from 256 husbands and wives in enduring marriages. For both spouses, midlife chronic stress influenced the occurrence of subsequent acute stressful life events, which in turn influenced both depressive symptoms and poor physical health in later years. For both spouses, midlife chronic stress also directly influenced depressive symptoms. Wives' midlife chronic stress also directly influenced their own poor physical health and husbands' depressive symptoms in later years. These findings enhance our knowledge about the long-term joint influence of midlife chronic stress and acute stressful life events on health outcomes of husbands and wives in later years and identify dependencies between spouses, which can inform health preventive intervention programs.
