Are hypertensive disorders of pregnancy (HDP) associated with breastfeeding initiation and duration?In this cross-sectional study representing over 10 million US women, HDP was associated with higher odds of never breastfeeding. Among those who initiated breastfeeding, HDP was associated with a higher hazard of breastfeeding cessation and fewer weeks of breastfeeding.These findings suggest that postpartum women with HDP may benefit from tailored interventions to promote the cardioprotective benefits of breastfeeding.
