Volunteering and Subsequent Health and Well-Being in Older Adults: An Outcome-Wide Longitudinal Approach

Background: Growing evidence documents strong associations between volunteering and favorable health and well-being outcomes. However, epidemiological studies have not evaluated whether changes in volunteering are associated with subsequent health and well-being outcomes.
Methods: Data were from 12,998 participants in the Health and Retirement Study—a large, diverse, prospective, and nationally representative cohort of U.S. adults age >50. Using multiple logistic-, linear-, and generalized linear regression models, we evaluated if changes in volunteering (between t0;2006/2008 and t1;2010/2012) were associated with 35 indicators of physical health, health behaviors, and psychosocial well-being (in t2;2014/2016). Models adjusted for sociodemographics, physical health, health behaviors, psychosocial factors, personality, as well as volunteering and all outcomes in the pre-baseline wave (t0;2006/2008). Results accounted for multiple testing and data were analyzed in 2019.
Results: Over the 4-year follow-up period, participants who volunteered ≥100 hours/year (versus 0 hours/year) had reduced risk of mortality and physical functioning limitations, higher physical activity, and better psychosocial outcomes (higher: positive affect, optimism, purpose in life and lower: depressive symptoms, hopelessness, loneliness, infrequent contact with friends). Importantly, volunteering was not associated with other physical health outcomes (diabetes, hypertension, stroke, cancer, heart disease, lung disease, arthritis, overweight/obesity, cognitive impairment, chronic pain), health behaviors (binge drinking, smoking, sleep problems), and psychosocial outcomes (life satisfaction, mastery, depression, negative affect, perceived constraints, living with spouse, contact with other family/children).
Conclusions: With further research, volunteering is an activity that physicians might suggest to their willing and able patients as a way of simultaneously enhancing health and society.
