Zinc supplementation in protein energy malnutrition.
A pair-matched controlled study was done with 30 children (15 males, 15 females) of mild to moderate PEM in test and equal number in control groups, aged 8-24 months old. At the beginning, in both test and control groups parents were advised to provide sufficient amount of home cooked foods so that the child received on an average 100-150 Kcal/kg/day of energy and 2-3 g/kg/day of protein. Vitamin supplements were provided to all children in both groups. In addition, the test group received a supplementation of 5.625 mg of elemental zinc daily orally while controls received a placebo. Evaluation at the end of 3 months showed that children in test group had a weight gain of 3.742 +/- 0.488 kg against 2.035 +/- 0.383 kg of the control group. Similarly, weight velocity was 5.752 +/- 0.818 g/kg/day in test group against 3.153 +/- 0.617 g/kg/day of the control group. These differences in weight gain and weight velocity were highly significant (p < 0.001). Serum zinc levels, initially and at the end of study were 87.5 +/- 9.6 micrograms/dl and 121.0 +/- 10.1 micrograms/dl, respectively in test group in comparison to 91.2 +/- 9.8 micrograms/dl and 91.0 +/- 10.1 micrograms/dl in controls. This difference was also highly significant (p < 0.001). The daily total calorie intake remained comparable in both groups. Our observations suggest that zinc supplementation during nutritional rehabilitation of mild to moderate PEM hastens the recovery.
