title: Predictors of preterm infant feeding methods and perceived insufficient milk supply at week 12 postpartum.
abstract: As part of a large, nonexperimental, prospective, longitudinal study, 94 pump-dependent mothers of a nonnursing preterm infant were queried via telephone at weeks 8 to 12 post-partum about their infant feeding method. At week 12, 44.6% provided own mother's milk, 26.6% provided own mother's milk + artificial milk, and 28.7% provided artificial milk only. Logistic regression analyses identified the following predictors for risk of artificial milk at week 12 postpartum: multiple birth, week 6 inadequate milk supply, maternal age younger than 29 years, and intended length of lactation less than 34 weeks. Predictors for risk of maternal perceived insufficient milk supply for weeks 8 to 12 postpartum included week 6 inadequate milk supply, unemployment, and infant hospital discharge after postpartum day 42. Further research is needed to assist pump-dependent mothers of preterm infants with sustaining their milk supply.
