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 well-baby visit after the first month of life, with birth weights between 1501 and 2500 g, and with nursery stays longer than 1 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.
