The authors studied three hypothesized explanations for reduced birth weights of infants born to US adolescent mothers—social disadvantage, biologic immaturity, and unhealthy behaviors during pregnancy. A hierarchical regression analysis was pursued to evaluate these explanations using data from the National Longitudinal Study of Youth on 1,754 first births between 1979 and 1983 to women aged 14–25 years at the time of birth. The birth weights of infants of mothers aged 14–17, 18–19, and 20–23 years were 133, 54, and 88 g less than for infants of mothers aged 23–25. The regression results indicate that the reduced birth weights of infants born to young mothers, particularly women aged 14–17, were related to their disadvantaged social environment. When adjustment was made for poverty and minority status, there were no maternal age differences in birth weight. The reduced birth weights were not related to the young woman's health behaviors during pregnancy or her biologic characteristics. Ethnicity, poverty status, age at menarche, maternal height, net maternal weight gain, and smoking during pregnancy had an independent effect on birth weight in this sample of young women.

We studied the relationship of young maternal age with infant hospitalization using data from the National Longitudinal Survey of Youth for 3,130 infants born between 1979 and 1983 to mothers aged 14-25 years. Data on the mothers were first collected in 1979 and yearly thereafter. Data on their children were collected starting in 1982. Logistic regressions of infant hospitalization rates were estimated for first and second and higher births. The odds of infant hospitalization during the first year of life increased with decreasing maternal age, even with adjustment for sociodemographic characteristics, preventive health-care practices, and newborn health status, factors hypothesized to explain the maternal age effect. The maternal age relationship with hospitalization differed by birth order; among second and higher births, the odds of hospitalization was increased only for infants of mothers aged 20-22 years. Male infants, infants with a first wellbaby visit after the first month of life, with birth weights between 1501 and 2500 g, and with nursery stays longer than one week also had increased odds of hospitalization. Ethnicity, grandmother's education, poverty status, mother's school enrollment, and family composition were not related to the odds of hospitalization, nor was smoking during pregnancy when adjustment was made for birth weight and length of nursery stay.
