Background: Early postnatal body weight changes (���� bw) and their clinical implications are poorly understood in preterm infants. We investigated the relationships between ���� bw and body fluid metabolism dependent morbidities in ELBW infants, the population which has highest incidences of such morbidities. ���� bw were evaluated as maximum weight loss (M����bw); and as daily body weight changes from birth weight (D���� bw) during the first 15 days of life. The mother-infants' variables relevant to body fluid balance, namely, oxygen dependence on day 28 (BPD28), patent ductus arteriosus (PDA), intraventricularperiventricular hemorrhage (IVH), antenatal steroid (ANS) and gestational age (GA) were correlated with M����bw and D���� bw via Pearson's correlation coefficient and Pearson's partial correlation tests. The effects of M����bw, as low (5-12% of birth weight) moderate (18.1-12%) and high (18-25%) were also assessed. Results: M����bw (n=102) was 14.2+/-5.4%. Day of life of M����bw was 5.5+/-2.1 and that of surpassing birth weight 14.5+/-4.2. M����bw correlated negatively with GA, ANS and pregnancy associated hypertension (PAH); and positively with BPD28, days on oxygen, fluid intake and urinary output in a GA dependent manner. M����bw did not correlate with RDS, hypotension, PIE, IVH, PDA and hospital stay. D���� bw correlated inversely with GA on days 1�¢����8, and was associated with decreased risks for BPD28, PDA and IVH after controlling for GA. ANS decreased D���� bw. Maternal diabetes mellitus (MDM) and PAH were not noted in mothers in high M����bw group. 38% of mothers in low M����bw group suffered from PAH. Conclusion: M����bw, governed by maturation, does not promote morbidities independent of GA within the range of 14.5+4.2%. D���� bw is protective for PDA, BPD28 and IVH independent of GA. ANS decreases D����bw, which correlates inversely with GA during the first week of life. MDM and PAH have implications in ���� bw in ELBW neonates.
