OBJECTIVE: To explore the effect of fortified human milk feeding on growth and complications of infants with extremely and very low birth weight (ELBW/VLBW) during hospital stay by a prospective, random and controlled study.METHODS: In the study, 122 ELBW/VLBW infants were enrolled and divided into two groups. The infants fed with human breast milk, combined with human milk fortification (HMF) during hospital stay were named HMF group (n=62), and those fed exclusively with premature formula were named premature formula feeding group (PF group, n=60). The data of the infants'growth (the velocity of increase on the weight, length, head circumference and upper arm circumference), the time of rebounding to birth weight, the time of needing intravenous nutrition, the time of hospitalizing, the proportion of extrauterine growth retardation (EUGR) during hospital stay, the level of hemoglobin, bone metabolism and incidence of complications were compared between the two groups.RESULTS: Among the 122 infants included, (1) the length increment in HMF group was higher than PF group [(0.89 ± 0.23) cm/week vs. (0.79 ± 0.34) cm/week, P=0.04]; there were no significant differences in the weight gain, head circumference increment and upper arm circumference increment (P>0.05); (2) the age of rebounding to birth weight [(10.13 ± 4.03) d vs. (8.03 ± 3.28) d, P=0.002] and the duration of intravenous nutrition [(16.77 ± 6.63) d vs. (14.23 ± 4.15) d, P=0.01] in HMF group were longer than that in PF group, there were no significant differences between the two groups in the hospital stay and age achieved feeding; (3) there were no significant differences between the two groups in the incidence rate of EUGR during hospital stay (P>0.05); (4) the level of calcium at birth in HMF group was lower than that in PF group [(2.19 ± 0.22) mmol/L vs.( 2.32 ± 0.27) mmol/L, P=0.005], and the level of alkaline phosphatase (AKP) in HMF group at discharge was higher than in PF group [(363.98 ± 122.49) mmol/L vs. (299.73 ± 117.39) mmol/L, P=0.004]; (5) the incidence of the feeding intolerance (6.5% vs. 18.3%, P=0.04) and sepsis (4.8% vs. 16.7%, P=0.03) in HMF group were less than in PF group, there were no significant differences between the two groups on the morbidity of necrotizing enterocditis, retinopathy of prematurity (ROP), and bronchopulmonary dysplasia (BPD) (P>0.05).CONCLUSION: HMF for premature infants may ensure the same growth pattern as those fed by premature formula, promote the calcium absorption, decrease the incidence of sepsis and feeding intolerance, and does not increase the incidence of necrotizing enterocolitis.

Objective To investigate the prevalence and risk factors of overweight and obesity among infants in Chongqing urban area, and to provide a basis for early intervention in cases of childhood obesity. Methods A total of 2139 infants aged one month were selected by stratified cluster sampling. They underwent growth monitoring and evaluation at 3, 6,9, 12 and 18 months after birth. Meanwhile, related factors were investigated using a standardized questionnaire. The data was subjected to multiple logistic regression analysis to determine the risk factors for overweight and obesity among infants aged 18 months. Results The detection rate of overweight and obesity increased rapidly after birth, reaching 26.04% at six months, and then decreased gradually, reaching 15. 89% at 18 months. Multiple logistic regression analysis revealed nine variable factors that were significantly correlated with overweight and obesity among infants aged 18 months, including nutritional status of the father, nutritional status of the infants at birth and at 6, 9 and 12 months after birth, feeding patterns at 3 months, frequency of vegetable intake at 12 months, frequency of sweet beverage addition at 18 months, and bedtime at 18 months. Conclusions Overweight and obesity are prevalent among infants in Chongqing urban area, and these conditions are affected by multiple factors. Early comprehensive intervention is recommended to curb prevalence. Source
