Volunteering and Hypertension Risk in Later Life

Abstract

Objective: This study examined the relationship between volunteer activity and hypertension, a risk factor for cardiovascular disease, renal failure, and cognitive impairment. Method: Employing data from the Health and Retirement Study, we estimated regression models of hypertension status that include volunteer activity and psychosocial and health behavior risk factors for middle-aged and older persons. Results: Multivariate analyses showed volunteers had lower hypertension risk and lower systolic and diastolic blood pressure than nonvolunteers and that a threshold effect was present, whereby a modest amount of volunteer time commitment (but not a high amount) was associated with lower risk of hypertension. We did neither find support that psychosocial and health behaviors mediated this relationship nor find support for a moderating effect of volunteering for the relationships among health behaviors and hypertension. Discussion: The results of this study indicate that research is needed to determine what mediates the relationship between volunteering and hypertension.
