Input: OBJECTIVE-To estimate risk of infant respiratory morbidity associated with cesarean delivery before labor and ruptured membranes among HIV-1-infected women. METHODS-In a prospective cohort study of HIV-1-infected women and their infants, mode of delivery was determined by clinicians at the participating sites. For this analysis, "elective cesarean delivery" was defined as any cesarean delivery, regardless of gestational age, without labor and with duration of ruptured membranes of less than 5 minutes. Nonelective cesarean deliveries were those performed after the onset of labor, rupture of membranes, or both. Vaginal delivery included normal spontaneous and instrument deliveries. Associations between mode of delivery and infant respiratory morbidity were assessed using χ 2 or Fisher's exact test. Adjusted odds of respiratory distress syndrome by delivery mode were assessed using multivariable logistic regression. RESULTS-Among 1,194 mother-infant pairs, there were significant differences according to mode of delivery in median gestational age (weeks) at delivery (vaginal, n=566, median=38.8; nonelective cesarean, n=216, median=38.0; and elective cesarean, n=412, median 38.1; P<.001) and incidence of respiratory distress syndrome (vaginal, n=9, 1.6%, reference; nonelective cesarean, n=16, 7.4%; elective cesarean, n=18; 4.4%; (P<.001). In analyses adjusted for gestational age and birth weight, mode of delivery was not statistically significantly associated
