Abstract


Objectives- To study the impact of Zinc supplementation from 4 to 9 month of age on growth of breast fed babies. Methods:- A case control study, it was carried out at Lata Mangeshkar Hospital between 2007 to 2009. A total of 123 patients were studied. They were divided into two groups. Group A of 61 infants were given zinc supplementation and Group B of 62 infants were not given any supplement. They were followed up till 9 month of age and anthropometric data was collected at monthly interval. Plasma zinc levels were measured at the start and the end of study. Results:- There was no difference in the zinc supplemented and non-zinc supplemented group in both sexes in relation to age of starting weaning food (mean age of weaning =6.1 months for both groups). At 4 month age, weight of both male and female infants were lower in the zinc supplemented group than the non-zinc group. At the end of 9 month, there was a significant increase in the weight of male infants in the zinc supplemented group (p va(ue= 0.0001). At the end of 9 month, the head circumference of male infants in zinc supplemented group was greater than that of non-zinc group (p value=0.03). At the end of 9 month there was no statistically significant difference in the chest circumference between the zinc supplemented and non-zinc group in both male and female infants. The serum zinc level at 4 month age was found to be significantly higher in the non-zinc group than the zinc supplemented group in both sexes. Conclusion:- Zinc though a trace element, in this study has been found to be an important nutrient contributing to growth of infants. The growth of male children is more affected by zinc supplementation than that of female infants. Studies at a larger level need to be conducted to support this observation. Key Words : breast fed babies, zinc supplementation.
