High-Risk Subsequent Births Among Co-Residential Couples: The Role of Fathers, Mothers, and Couples.

This study examines predictors of a cumulative measure of high-risk births, rather than single risks separately, as in prior research. Using the Early Childhood Longitudinal Study-Birth Cohort survey, we incorporate data from fathers and mothers to assess characteristics associated with births subsequent to a focal child's birth within high-risk circumstances. Components of a high-risk birth include: high-parity, very closely-spaced, or births to unmarried couples, unhappy couples, or couples in high-conflict relationships. Both fathers' and mothers' pregnancy intentions affect whether couples have a subsequent high-risk birth. The odds of a high-risk subsequent birth, relative to no birth and to a low-risk birth, are more than twice as high if only the father intended the birth of the previous child rather than if the child was intended by both the mother and father. High-risk subsequent births are much more likely among couples where the prior child was high risk and where family income was low, and lower where both father and mother had lived with both biological parents. Findings highlight the importance of father data in fertility research.
