Family Health Stress and Insomnia Symptoms Among Older Adults: The Moderating Role of Activity Engagement.

Insomnia symptoms arising from stress present significant health risks for older adults, yet few studies have examined (1) the association between family health-related stress and insomnia or (2) the moderating role of activity engagement. This study used data from the 2016 and 2018 Health and Retirement Study (N = 5565) to assess these relationships using linear regression models. The study focused on 4 insomnia symptoms and 15 activity items, adjusting for sociodemographic characteristics and health factors. Higher levels of family health stress were significantly associated with higher numbers of insomnia symptoms. The moderation analysis showed that engagement in social and hobby activities weakened this association, suggesting that certain activities serve a buffering role in reducing family health stress-related insomnia symptoms.
