Serum zinc level in preterm low birth weight babies and its comparison between preterm AGA and preterm SGA babies.

Abstract

Low birth weight (LBW) is a major child health problem in Bangladesh and continuing to great threat to child health and child survival in Bangladesh. LBW is a silent emergency but crisis is real and its persistence has profound and frightening impact on neonatal mortality. This observational study was conducted in Dhaka Shishu Hospital, Dhaka, Bangladesh during July 2004 to June 2005. Serum zinc levels were estimated between two groups: group-I preterm AGA (n=50), group II preterm SGA (n=50) babies. Blood samples were collected from the study population in neonatal unit and serum zinc levels were measured by flame atomic absorption spectrophotometry in Atomic Energy Center, Dhaka, Bangladesh. Observed data were made comparison among groups by Students 't' test. It was observed serum zinc level (60.2+/-15.2) in group I and (62.1+/-12.4) in group II. Serum zinc level was in lower limit of normal range in both groups with more lower level in preterm AGA babies but their difference was not statistically significant (p>0.05). So zinc supplementation may enhance the growth of preterm LBW babies in their early months of lives.
