후기 미숙아의 모유수유 실천 정도와 모유수유 실천 예측 요인: 재태기간 34주 미만 미숙아와의 비교 분석 = Breast Feeding Rates and Factors Influencing Breast Feeding Practice in Late Preterm Infants: Comparison with Preterm Born at Less than 34 Weeks of Gestational Age

다국어 초록 (Multilingual Abstract)

Purpose: This study was done to compare breast feeding rates and factors influencing feeding practice between late preterm (34≤GA<37) and preterm infants (GA<34). Methods: A survey was done of 207 late preterm and 117 preterm infants in neonatal intensive care units (NICU) of 4 university hospitals in D city. Data were collected from July 2009 to June 2010 from 324medical records in the NICU. Breast-feeding at home was checked either by telephone survey or questioning during hospital visits. Results: Rate of breast feeding for late preterm infants was significantly lower than for preterm infants. There was no significant difference in breast-feeding at home. We found differences in factors influencing breast feeding between the two groups. Factors influencing feeding for late preterm infants were type of delivery, mothers' occupation, feeding type during hospitalization, time elapse from hospital discharge, total admission days, infant's body weight at first feeding and length of NPO (nothing by mouth). Factors influencing feeding for preterm infants were birth order, maternal disease and obstetric complications,and one-minute Apgar score. Conclusion: Results of the study show low rates of breast-feeding for late preterm infants indicating a need for breast-feeding education for mothers of these infants.
