This study investigates the longitudinal associations between volunteering among older adults and the cognitive functioning for the purpose of preventing the cognitive decline, examining how volunteerism of older persons affects the cognitive functioning. For the purpose, the study analyzes about 8,688 older subjects who are observed six times with intervals of two years, using statistical analysis model of linear multilevel mixed regression. The results show that volunteering is associated with higher level of cognitive function over time, and the education moderates the association, with volunteering benefiting the most differentially least-educated elderly among four higher-educated groups. Also age weakens the effect size of volunteering, but volunteering effects work in all ages. Volunteering is lifestyle behaviors that enhance cognitive functioning of older persons. The results suggests that cognition-strengthened volunteer programs are beneficial to older persons at the population level.
