Logistic regression results with infant admission to an intensive care unit as the dependent variable: the infant is more likely to be admitted to an ICU if the mother was having her first birth, had no education past high school, lived in a household with an annual income < 20,000/year, lived in an urban or suburban area, or had a gestational weight gain < recommended range (compared to within recommended range). The infant was less likely to be admitted to an ICU if the mother had a higher prepregnancy BMI or a pregnancy weight gain > recommended range (compared to within recommended range).
