Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (95% CI). Preterm delivery cases were studied in aggregate, in subgroups (spontaneous preterm labor, preterm premature rupture of membranes, medically induced preterm delivery, moderate preterm delivery [gestational age at delivery 34\u201336 weeks], and early preterm delivery [gestational age at delivery &lt;34 weeks]). <jats:italic>Results.<\/jats:italic> After adjusting for confounders, women weighing &lt;2,500 g at birth had a 1.54\u2010fold increased risk of preterm delivery versus women weighing = 2,500 g (95% CI 0.97\u20132.44). Maternal low birth weight was associated with a 2\u2010fold increased risk of spontaneous preterm delivery (95% CI 1.03\u20133.89), but weakly associated with preterm premature rupture of membranes (OR = 1.44; 95% CI 0.67\u20133.09) and medically induced preterm delivery (OR = 1.10; 95% CI 0.43\u20132.82). Maternal low birth weight was more strongly associated with early preterm delivery (OR = 1.94) than with moderate preterm delivery (OR = 1.46).
