RESUMO
OBJECTIVE: To systematically evaluate the association of early nutrition intake with the risk of bronchopulmonary dysplasia (BPD). METHODS: PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data, and Weipu Periodical Database were searched for the observational studies on the association between early nutrition intake and BPD. RevMan 5.3 software was used to perform a Meta analysis of eligible studies. RESULTS: Eight observational studies were included, with 548 infants with BPD and 522 infants without BPD. The Meta analysis showed that the BPD group had a significantly lower caloric intake than the non-BPD group within the first week after birth and in the first 2 weeks after birth (P < 0.05). The BPD group had a significantly lower enteral nutrition intake than the non-BPD group (WMD=-18.27, 95%CI:-29.70 to -6.84, P < 0.05), as well as a significantly lower intake of carbohydrate, fat, and protein (P < 0.05). The BPD group had a significantly longer duration of parenteral nutrition than the non-BPD group (WMD=14.26, 95%CI:13.26-15.25, P < 0.05). CONCLUSIONS: Early nutrition deficiency may be associated with the development of BPD, and more attention should be paid to enteral feeding of infants at a high risk of BPD to achieve total enteral feeding as soon as possible.
