1153Marital dissolution in later life: Change in health behaviours and outcomes following divorce and widowhood
Abstract Background Marital dissolution, such as divorce and widowhood, are common life events with potentially important implications on health. Previous research has found that those who have divorced or widowed tended to have a higher risk of mortality, however, the mechanisms for the observed associations are not well understood. We aimed to examine the association of divorce and widowhood with subsequent changes in health-related lifestyles, psychological outcomes, and overall health and wellbeing within both immediate and longer terms. Methods We used data from the 45 and Up study collected at baseline (T1, 2006-09), first (T2, 2010) and second follow-up (T3, 2012-16). Martial status and health-related outcomes were self-reported at all three time-points using validated questionnaires. Nine outcomes were examined, including lifestyles (smoking, drinking, diet and physical activity), psychological outcomes (distress, anxiety and depression) and overall health/well-being (self-rated health and quality of life). Logistic regression and generalised estimating equations were conducted adjusted for sociodemographic characteristics. Results Of the 33184 participants who were married/co-habiting at T1, after 3.4 years, 2.9% became divorced and 2.4% widowed. Those who divorced had much higher odds of smoking, having poor quality of life, high psychological distress, anxiety and depression at T2. Similar but weaker associations were observed for those who became widowed. After another 5 years of follow-up, however, the associations were much attenuated towards the null. Conclusions We found strong adverse short-term effects of marital dissolution on health outcomes, particularly within the psychological health domain. The effects, however, seemed to attenuate in the longer terms.
