A randomized trial of over five hundred black and Latina mothers studied the effects of a post-delivery culturally-tailored educational intervention on the duration of breast feeding. The intervention group mothers received an in-hospital educational session with a social worker, educational materials, and a two-week follow-up call. Education addressed breastfeeding, nipple pain, cesarean delivery, site pain, episiotomy site pain, urinary incontinence, back pain, headaches, hair loss, hemorrhoids, infant colic, and depressive symptoms. Additional information on social support was also provided. The intervention was associated with a longer duration of breastfeeding and with fewer mothers quitting breast-feeding in the first six months of life.
