ObjectiveTo assess the influence of the quality of antenatal care on early breastfeeding initiation and exclusive breastfeeding among Haitian women. DesignSecondary analysis of a cross-sectional household survey. SettingHaiti Demographic and Health Survey, 2016 to 2017. ParticipantsWomen (N = 2,489) who were 15 to 49 years of age with children younger than 24 months of age. MethodsWe used multivariable adjusted logistic regression analysis to examine the independent associations between quality of antenatal care and early breastfeeding initiation and exclusive breastfeeding. ResultsThe prevalence of early breastfeeding initiation and exclusive breastfeeding were 47.7% and 39.9%, respectively. Approximately 76.0% of the participants received intermediate antenatal care. The odds of early breastfeeding initiation were greater among participants who received antenatal care of intermediate quality than among those who did not receive antenatal care, adjusted OR (AOR) = 1.58, 95% confidence interval (CI) [1.13, 2.20]. Additionally, maternal age of 35 to 49 years (AOR = 1.53, 95% CI [1.10, 2.12]) was positively associated with early breastfeeding initiation. Factors negatively associated with early breastfeeding initiation were cesarean birth (AOR = 0.23, 95% CI [0.12, 0.42]), birth at home (AOR = 0.75, 95% CI [0.34, 0.96]), and birth in a private facility (AOR = 0.57, 95% CI [0.34, 0.96]). Factors negatively associated with exclusive breastfeeding were employment (AOR = 0.57, 95% CI [0.36, 0.90]) and birth in a private facility (AOR = 0.21, 95% CI [0.08, 0.52]). ConclusionAntenatal care of intermediate quality was positively associated with early breastfeeding initiation among women in Haiti, which highlights the influence that care during pregnancy can have on breastfeeding outcomes.
