Family structure and child health outcomes in the United States.

We use categorical and logistic regression models to investigate the extent that family structure affects children’s health outcomes at age five (i.e., child’s type of health insurance coverage, the use of a routine medical doctor, and report of being in excellent health) using a sample of 4,898 children from the "Fragile Families and Child Well-Being Study." We find that children with married biological parents are most likely to have private health insurance compared with each of three other relationship statuses. With each additional child in the home, a child is less likely to have private insurance compared with no insurance and Medicaid insurance. Children with cohabiting biological parents are less likely to have a routine doctor compared with children of married biological parents, yet having additional children in the household is not associated with having a routine doctor. Children with biological parents who are not romantically involved and those with additional children in the household are less likely to be in excellent health, all else being equal.
