    Journal: Early Hum Dev; 2023 Mar; 177-178():105730. PubMed ID: 36822127.
    Abstract:
    BACKGROUND: Feeding mother's own milk (MOM) is associated with reduced morbidity of very low birth weight (VLBW) infants (<1500 g), but not all mothers are able to provide pumped breast milk or breastfeed until discharge. AIMS: To investigate the duration of MOM feeding and identify risk factors for cessation. STUDY DESIGN: Single-center retrospective cohort study. SUBJECTS: 307 VLBW infants born 2012 and 2019 surviving beyond 7 days of life. OUTCOME MEASURES: Analysis of MOM feeding at discharge, including comparison with a historical cohort of infants born 1992-1994. RESULTS: MOM feeding was initiated in 178/180 infants (98.9 %) born in 2012 and in 123/127 infants (96.9 %) born in 2019 (p = 0.132), as compared to 73/89 (82 %) infants born 1992-1994 (p < 0.001). Median [range] duration of MOM feeding was similar for infants born in 2012 (45 [0-170] days) and 2019 (50 [0-190] days) (p = 0.396), but much longer than in the historical cohort (36 [0-152] days) (p < 0.001). The overall breastfeeding rate increased up to 69.2 % and 77.2 %. Factors associated with cessation of MOM feeding were smoking during pregnancy, single-mother status, short (<12 years) duration of maternal or paternal school education (all p ≤ 0.001), natural conception, birth weight ≥ 1000 g, and gestational age ≥ 29 weeks (p < 0.05). In Cox proportional hazard multivariate analysis, smoking during pregnancy and single-mother status remained independent risk factors. CONCLUSIONS: Duration of MOM feeding and breastfeeding rates of VLBW infants during hospital stay have increased significantly during the last 30 years, while smoking and indicators of low socioeconomic status remain dominant predictors of cessation of MOM feeding.
