 note = {Appropriate physical activity (PA) enhances health-related quality of life (HRQOL) in the elderly. However, few studies have focused on the physical activity required during grandparenting activities. We investigated the levels of PA and HRQOL in 48 Japanese grandmothers and determined the association between child-rearing assistance and PA and between PA and HRQOL. The study revealed that the grandmothers mainly provided nondaily care, and they showed an appropriate level of PA and good physical and mental HRQOL. These findings suggest that involvement in non-routine care has benefits for grandparents’ health.},
