Aims: To identify infant and maternal factors associated with attainment of full oral feeding (FOF) in premature infants.Method: A retrospective study was performed on 89 premature infants (<34 weeks gestational age) from a tertiary care neonatal intensive care unit (NICU). Infant and maternal factors were concurrently assessed. Infant factors included gestational age, birthweight, continuous positive airway pressure assistance, mechanical ventilation support, and presence of neonatal morbidities including bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), and intraventricular hemorrhages (IVH). Maternal factors included maternal age, first born, twin birth, and presence of mental health conditions including anxiety, stress, or depression.Results: A total of 89 premature infants were included in the sample. A stepwise linear regression model revealed that infants who received mechanical ventilator support and presence of maternal mental health conditions were significantly associated with time to attain FOF.Conclusions: Results suggest that oral feeding performance is influenced not only by infant's medical severity denoted by need for ventilator assistance, but also by presence of maternal anxiety, stress, and/or depression.
