- Abstract
Objective: To determine influences on incidence of breast milk feeding (BMF) at time of discharge and 6 months later among infants cared for in the neonatal intensive care unit (NICU)., Design: A 2-year prospective descriptive NICU hospital-based cohort design., Setting: Academic Center Level III-IV NICU., Participants: Five hundred and thirty-five infants cared for in NICU and a subgroup of one hundred twenty-nine participant mothers who answered questionnaires., Methods: Predischarge data were collected using maternal and infant medical records. Post-discharge data were collected from maternal questionnaires., Results: At NICU discharge, biophysiologic stressors predictive of not receiving BMF included birth weight <1500 grams (p < .035), heart surgery (p = .014), and inhaled nitric oxide treatment (p = .002). Teenage mothers were less likely to BMF (p = .022). After discharge, BMF duration correlated with BMF duration of a prior infant (p < .009). Most mothers reported BMF >4 months, 91% continued pumping, and 89% indicated an interest in a hospital support group. Logistic regression analysis (R(2) 0.45) identified factors that significantly increased the likelihood of BMF > 4 months: BMF plan (p < .001), convenience (p = .018), and family as resource (p = .025). Negative associations were: awareness of immune benefits (p = .025), return to work (p = .002), and infants requiring surgical ligation of the patent ductus arterious (p = .019)., Conclusions: Social and medical stressors contribute to BMF duration pre- and post-NICU discharge. We speculate that active NICU BMF support targeting vulnerable infants and their families and assisting with plans for BMF pre- and post-discharge will help overcome barriers., (© 2012 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.)
