Key Influences on Oral Feeding Achievement in Preterm Infants: Insights From a Tertiary Hospital in Indonesia.

: Effective oral feeding is one of the critical milestones that must be achieved by preterm infants. While gestational age and birth weight have been recognized as influential factors, recent studies have found additional variables impacting the achievement of full oral feeding (FOF). This study is aimed at describing factors associated with the attainment of FOF in preterm infants. : This retrospective cohort study examines preterm infants born between 28 and 34 weeks' gestation admitted to Dr. Cipto Mangunkusumo General Hospital in Jakarta between July and December 2016. Comparative analysis utilized the Kruskal-Wallis test, while Cox's regression was employed for multivariate analysis to assess factors influencing the achievement of FOF. : This study included 87 preterm infants meeting the inclusion criteria. The median gestational age was 33 weeks (IQR: 3). The most common birth weight range was 1500-1999 g (51.7%). Median durations from birth to the first feed, full enteral feed, and FOF were observed to be 1 day (IQR: 1), 6 days (IQR: 10), and 14 days (IQR: 24), respectively. Notably, the duration of oxygen therapy, episodes of sepsis, and frequency of blood transfusions showed significant associations with the time taken to achieve FOF. : This study found significant associations between the time to achieve FOF and factors such as oxygen therapy duration, sepsis episodes, and frequency of blood transfusion. These findings highlight the importance of considering these factors in managing preterm infants. However, a further prospective study is warranted to identify additional factors that influence feeding milestones in preterm infants.
