How does the age of the youngest child affect parental survival?

Abstract

AbstractPrevious research has investigated several different aspects of the relationship between having a child and parental mortality. One aspect of research that has been neglected until now is the age of the child. If children have an effect on parental mortality, this is likely to change as they grow up. We apply hazard regression models to longitudinal Swedish register data of the total population for men and women separately. Adjusting for a variety of control variables, we find that parents with younger children experience a substantive mortality advantage compared to parents—of the same age—who have older children. The mortality advantage decreases gradually as the age of the youngest child increases. Robustness checks confirm that this result cannot be explained by differences in the parent’s age and parental age at first birth. Childless women and men of the same age experience the highest mortality. Additional models for different causes of death suggest that selection, behavioral changes, and unobserved protective effects contribute to this pattern.
