The extremely low birth weight infants (ELBW, birth weight &lt;1000\u200ag) have the highest incidence of such morbidities among all neonates.<\/jats:p>\n                  <jats:p>AIM: To determine the relationships between \u0394 bw and neonatal morbidities associated with body fluid metabolism in the ELBW infants.<\/jats:p>\n                  <jats:p>METHODS: In an observational study, the associations between daily weight changes from birth weight (D\u0394 bw) and oxygen dependence on postnatal day 28 (BPD28), patent ductus arteriosus (PDA), intraventricular-periventricular hemorrhage (IVH), antenatal steroid (ANS) and gestational age (GA) were evaluated. Maximum weight loss (M\u0394 bw) was correlated with GA, BPD28 and BPD36 (oxygen dependence on postmenstrual 36 weeks). Pearson\u2019s correlation co-efficient and multivariate logistic regressions were performed for analysis.<\/jats:p>\n                  <jats:p>RESULTS: D\u0394 bw correlated inversely with GA on days 1\u20138 of life ( p\u200a&lt; \u200a0.01 for all, 0.06 for DOL 2). D\u0394 bw was associated with a lower risk of BPD28 on days 6 (OR 0.87, 95% CI 0.76\u20131), 10 (OR 0.86, 95% CI 0.76\u20130.98) and 11 (OR 0.87, 95% CI 0.77\u20130.99); with PDA on days 8\u201311 (OR ranging between 0.89 to 0.92 for the 4 days, 95% CI 0.83 to 0.99) and with IVH on day 5 (OR 0.93, 95% CI 0.86\u20131) after controlling for GA. D\u0394 bw was not identified as risk factor for the tested morbidities. ANS decreased D\u0394 bw on days 4 (OR 0.88, 95% CI 0.78\u20131) and 10 (OR 0.9, 95% CI 0.84\u20131). M\u0394 bw correlated directly with BPD28 ( r\u200a=\u200a0.3, p\u200a=\u200a0.004), which declined after controlling for GA ( r\u200a=\u200a0.2, p\u200a=\u200a0.2).<\/jats:p>\n                  <jats:p>CONCLUSIONS: D\u0394 bw is protective for PDA, BPD28 and IVH, independent of gestational age, whereas, the effects of M\u0394 bw on BPD are governed by maturation in ELBW infants. ANS decreases D\u0394 bw, which correlates inversely with GA during the first week of life.<\/jats:p>","DOI":"10.3233\/npm-15814104","type":"journal-article","created":{"date-parts":[[2015,8,6]],"date-time":"2015-08-06T09:25:25Z","timestamp":1438853125000},"page":"113-118","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Do
