Is having more children beneficial for mothers’ mental health in later life? Causal evidence from the national health and aging trends study

Abstract

Objectives Members of the baby boom cohorts had fewer children than their parents. Given that adult children are an important source of social support in later life, this may have implications for the mental health of new cohorts of older people. This study investigates whether having additional children protects white mothers aged 65 and older against mental health problems. Method Data are from Wave 1 and Wave 5 of the National Health and Aging Trends Study (n = 3,845). An instrumental variable approach exploiting the preference for mixed-sex offspring is used to estimate the causal effect of additional children on the risk of elevated depression and anxiety symptomatology. Results The estimated instrumental variable model shows that additional children reduce the risk of suboptimal mental health among white mothers aged 65 and older. Conclusion Results suggest that declines in higher-order births may put new cohorts of older women at increased risk of suboptimal mental health.
