Volunteering and Risk of Heart Attack in Later Life: The Moderating Role of Purpose in Life?

<b>Objectives:</b> We investigate whether volunteering is associated with a reduced risk of first heart attack in later life and whether purpose in life moderates this relationship. <b>Methods:</b> Cox proportional hazards were used to examine seven waves of data (2006-2018) from the Health and Retirement Study-a nationally representative survey of adults 50 years and older (<i>N</i> = 5,079). <b>Results:</b> Volunteering a moderate number of hours was associated with a 46% lower risk of heart attack compared to non-volunteers. The association between high time-commitment volunteering and heart attack risk was contingent on level of purpose in life: compared to non-volunteers, people with high purpose in life who volunteered 100 + hours had the lowest risk of heart attack. <b>Discussion:</b> Meaningful volunteer activities may be one way for older adults to reduce their risk of heart attack.
