Objective: To determine the prevalence and correlates of the early discontinuation of breastfeeding by mothers eligible for the Women, Infants, and Children Program (WIC).
Methodology: A longitudinal observational study in which we enrolled English-speaking mothers who initiated breastfeeding after delivering healthy-term infants at Yale-New Haven Hospital and planned to bring their infants to the hospital's primary care center. Data on mother's baseline knowledge, attitudes, beliefs, and problems regarding breastfeeding were collected by semistructured interviews within 48 hours after delivery, at 1 and 2 weeks' postpartum, and by chart reviews at 2 and 4 months. A nonparticipating control group was used to test the Hawthorne effect.
Results: Of the 64 participating mothers, the majority were minority (56% black, 34% of Puerto Rican origin), single (75%), and already enrolled in WIC (91%). The rates of discontinuation of breastfeeding were 27%, 37%, 70%, and 89% by 1 week, 2 weeks, 2 months, and 4 months, respectively. The mother's knowledge and problems of lactation were not associated with the early discontinuation of breastfeeding. After using logistic regression to control for potential confounders, mothers who lacked confidence at baseline that they would still be breastfeeding at 2 months (risk ratio: 2.38, 95% confidence interval: 1.82-6.18), and those who believed that the baby prefers formula (risk ratio: 1.68, 95% confidence interval: 1.04-2.71) were more likely to stop breastfeeding within the first 2 weeks postpartum.
Conclusions: The results of this study demonstrate that interventions aimed at prolonging the duration of breastfeeding in this population will need to shift focus from increasing knowledge and managing problems of lactation to enhancing the mother's confidence regarding breastfeeding, while also addressing beliefs regarding an infant's preferences.
