Abstract
In this prospective study, birth weight of 304 babies born at Kamla Nehru Hospital Pune during study period was recorded. From these 304 babies, babies with birth weight above 2000 grams were selected (260 babies) to prepare growth velocity curves. Daily weight of these 260 babies was recorded for 30 days. The mean birth weight of study population was 2742.5 grams. Among the daily weight recorded babies, all the babies lost weight ranging from 92 to 218 grams (mean 121 grams) after birth. The weight loss continued upto 5 days. Days required to gain weight equal to birth weight ranged from 5 to 13 days. Total weight gain observed in 30 days was 734.7 grams. Predictive value of these curves was tested in 49 infants. Deviation upto 50 grams of predicted birth weight from actual birth weight was observed in 90% of babies on day-2, 79% on day-4, 65% on day-8 and 39% on day-30.
