Abstract:
Objective To analyze the nutritional status of premature neonates first fed with extensively hydrolyzed protein formula.Methods From January 2013 to December 2014, 157 premature neonates hospitalized in Neonatal Intensive Care Unit of Shanghai Children's Medical Center who were first fed with extensively hydrolyzed protein formula were enrolled.Clinical data were recorded, including related diseases, birth weight and gestational age, nutrients intake, and growth charts.Two groups were divided according to the existence or absence of feeding intolerance, and three groups were divided based on birth weight (＜ 1 500 g, 1 500 ～ 2 500 g,and ≥2 500 g).Results A total of 60 (38.2％) premature infants had feeding intolerance.The lower the birth weight and gestational age, the higher the frequency of feeding intolerance, and the incidence of feeding intolerance in ＜ 1 500 g group was 71.1％.Compared with the feeding tolerance group, the feeding intolerance group had significantly smaller birth weight [(1 620 ±440) g vs.(1 980 ±421) g, P =0.000], gestatonal age [(31.3 ±2.6) weeks vs.(33.0 ±2.1) weeks, P =0.000], birth head circumference [(28.9 ±2.2) cm vs.(30.4±1.9) cm, P=0.000], and birth length [(41.1 ±3.9) cmvs.(43.2±3.4) cm, P=0.000],but significantly longer time before transfer formula [(26.4 ± 17.6) d vs.(7.9 ± 5.3) d, P =0.000] and time before reaching sufficient feeding [(21.5 ± 10.0) d vs.(13.8 ± 6.2) d, P =0.000].The time of first feeding [＜ 1 500 g group (6.1 ±5.1) d, 1 500 ～2 500 g group (3.8 ±2.5) d, ≥2 500 g group (3.3 ± 1.2) d,P =0.002], time before transfer formula [＜ 1 500 g group (28.7 ± 18.3) d, 1 500 ～ 2 500 g group (9.7 ± 8.1) d, ≥2 500 g group (7.0 ±3.8) d, P =0.000] and time before reaching sufficient feeding [＜ 1 500 g group (24.0±10.4) d, 1 500～2 500 g group (14.3±6.0) d, ≥2 500 g group (11.4±3.5) d, P=0.000] increased along with the decrease of birth weight.The proportions of infants receiving parenteral nutrition in the feeding intolerance group (93.3％) and ＜ 1 500 g group (97.8％) were higher, with more calorie intake from parenteral nutrition [＜ 1 500 g group (325.9 ± 59.4) kJ/ (kg · d), 1 500 ～ 2 500 g group (281.2±64.8) kJ/ (kg·d), ≥2 500 g group (269.9 ±43.9) kJ/ (kg·d),P=0.001] and longer duration [＜ 1 500 g group (27.1 ± 14.5) d, 1 500 ～2 500 g group (13.0 ±7.0) d, ≥2 500 g group (8.7 ± 3.4) d, P =0.000].In terms of growth indicators, the increase in head circumference was significantly higher in the feeding intolerance group than in the feeding tolerance group [(0.7 ± 0.6) cm/week vs.(0.6 ± 0.5) cm/week, P =0.045].The increases in body weight and head circumference in the ＜ 1 500 g group were significantly higher than in the other 2 birth weight groups [body weight: ＜ 1 500 g group (21.8 ± 9.5) g/d, 1500～2500ggroup(4.2±7.6) g/d, ≥2 500 g group (4.9 ±11.9) g/d,P=0.000;head circumference : ＜ 1 500 g group (0.8 ± 0.4) cm/week, 1 500 ～ 2 500 g group (0.5 ± 0.4) cm/week, ≥ 2 500 g group (0.6 ± 0.8) cm/week, P =0.005].After controlling the variable of feeding intolerance,weight gain was negatively associated with gestational age (r =-0.666, P =0.035), birth weight (r =-0.700, P =0.024), head circumference (r =-0.846, P =0.002), and the day of returning to birth weight (r =-0.697, P =0.025), while positively associated with head circumference gain (r =0.672, P =0.033).There were no relationship between weight gain and birth length, the day of first feeding, time before transfer formula, time before reaching sufficient feeding, parenteral nutrition calorie and duration, days of hospital stay and complications.Conclusions First fed with extensively hydrolyzed protein formula, the growth in feeding intolerant premature infants may be similar to the feeding tolerant ones, which is associated with parenteral nutrition support.Premature infants with lower gestational age, birth weight, and head circumference may be more suitable for extensively hydrolyzed protein formula feeding.
