Family influences and birth outcomes among adolescents

We examined how family influences are related to birth outcomes (birth weight and gestational age) among adolescent mothers, using data from the National Longitudinal Study of Adolescent Health. Women whose first pregnancy reported in Wave IV occurred after Wave I, during their adolescence and ended with a singleton live birth were included. To account for sample selectivity, we adjusted the sampling weights by multiplying the Wave IV sampling weights by the inverse of predicted probabilities of getting pregnant during adolescence as well as that of having a live birth. Multivariable analysis was used to model outcomes; predictors included baseline age, parent-child relationship variables, discussions of sex and birth control, parental disapproval of sex and family socio-economic variables. Among Black adolescents, higher level of parental disapproval, more discussion about sex, less discussion about birth control, parental inability to pay bills and not receiving public assistance were associated with lower birth weight; the same set of variables as well as living with two bio-parents were associated with lower gestational age. Among non-Black adolescents, moderate discussion of birth control and ever being a runaway or “ordered out” were associated with higher birth weight; ever being a runaway or “ordered out” was also related to higher gestational age. The effects of family influences on adolescent birth outcomes were mixed. The mechanism driving these unanticipated effects needs to be explored.
