Complementary feeding in infants born preterm: Aspects needing improvement

Abstract

ObjectiveThe aim of our study was to collect data on complementary feeding (CF) in preterm infants (PIs).MethodsWe enrolled PI ≤ 34 weeks of gestational age discharged from the neonatal intensive care unit (NICU) of the University Hospital of Padova. At 12 months of corrected age (CA), CF was investigated with questionnaires to the parents and a 24‐h dietary recall. In a subgroup of newborns, we also evaluated bone status at a CA of 12 months using quantitative ultrasound.ResultsWe studied 167 ex PI at 1 year of CA. CF was introduced in 67.1% of them between 5 and 8 months of chronological age, with fruit as the first food (81%, n = 136). Sweet drinks were consumed by 17.4% of our sample, and salt was added in 33.5% of cases. PIs, at 1 year CA, introduced extra energy compared to the theoretical requirement (121 ± 31 kcal/kg/day) and higher protein intake than recommended (39 ± 11 g/day), while the intake of both total lipids and carbohydrates was slightly lower. Vitamins and minerals were adequate, except vitamin D. Regarding bone status, we found a correlation between vitamin D intakes from the diet and bone parameters (metacarpus‐bone transmission time: r = 0.36, p = 0.01) at 1 year of CA.ConclusionsOur population of PIs started CF in agreement with current suggestions though with a notable heterogeneity and with some mistakes. Vitamin D intake was correlated with bone status at 1 year of CA.
