Clinical Evaluation of Postnatal Weight Gain in Premature and Low Birth Weight Infants

  • 1Department of Pediatrics, Kwangju Christian Hospital, Korea.


Among premature and low birth weight infants admitted between March 1970 and February 1977, 228 infants who were clinically normal and older than 7 hospital days are evaluated as to the changes of baby weight. The average postnatal weight loss was 18 to 8 per cent during the first 7 to 17 days after birth. Infants refained their birth weight at the age of 15 to 17 days in the weight group of 1001 to 1250g 9 to 10 days in 1251 to 1500g, 13 to 15 days in 1501 to 1750g, 14 to 16 days on 1751 to 2000g, 11 to 13 days in 2001 to 2250g, 7 to 8 days in 2251 to 2500g. Postnatal weight gain in this study corresponded well to Dancis postnatal growth curve.
