Risk factors for discontinuation of exclusive breast feeding within 1-month: A retrospective cohort study

Background: While breastfeeding provides both optimal nutrition for infants and health benefits for the mother, many women either do not breastfeed or terminate breastfeeding earlier than recommended. The aim of this analysis was to identify factors associated with early discontinuation of breastfeeding in Japanese women.Methods: This study utilized medical records from the Iwase General Hospital in Fukushima Prefecture, Japan to assess cessation of breastfeeding by the 1-month postpartum appointment. Demographic, medical, and family predictors among 734 women who had initiated breastfeeding during their delivery hospital stay were examined, and multiple logistic regression was used to determine significant predictors of early cessation of exclusive breastfeeding.Results: In a bivariate analysis, it was observed that women who were primipara, unmarried, smoked before pregnancy, were exposed to secondhand smoke, employed, and/or had asthma were more likely to discontinue exclusive breastfeeding. Infant factors associated with discontinuation were lower birthweight, earlier gestational age, neonatal intensive care unit admission, treatment for jaundice, or lower weight gain. In multivariable analysis, primiparity, smoking before pregnancy, maternal employment and neonatal jaundice therapy remained associated with discontinuation of breastfeeding.Conclusions: Several maternal factors are associated with discontinuation of exclusive breastfeeding. In particular, women who smoke before pregnancy may need to be targeted for additional support for breastfeeding.
