Iron and Zinc Status of 6-Month to 5-Year-Old Children From Low-Income Rural Families of Punjab, India

Background: Iron and zinc are the 2 micronutrients that are deficient in the diet of the people of Third World countries.

Objective: Assessment of iron and zinc status of 6-month to 5-year-old children from low-income rural families of Punjab, India.

Methods: Thirty clusters (villages) from 12 blocks of Ludhiana district of Punjab, India, were chosen randomly to select 413 households of agricultural laborers and of small and marginal farmers to obtain a sample of 312 children (6 months to 5 years).

Results: Wheat is the major contributor of iron (65.5%) and zinc (58.0%) in the diets of children. The percentage of adequacy of iron in 0.5- to 2-year-old and 3- to 5-year-old children was 18.5% and 37.2% when compared to the estimated average requirements of World Health Organization/Food and Agriculture Organization. The corresponding zinc adequacy was only 7.2% and 25.3%, respectively. The results showed that 65% of 2- to 5-year-old children had dietary zinc adequacy. Serum zinc values below normal values were 17.9%, whereas 84.6% and 71.8% of children had low serum iron and serum ferritin levels, respectively. The raised soluble transferrin receptors were found in 79.8% of children. Anemia was found in 55.8% children, of which 20.2%, 33.0%, and 2.9% of children were mildly, moderately, and severely anemic, respectively.

Conclusions: Iron-deficiency anemia is a more serious problem among reference children, however, zinc deficiency also prevails. The suboptimal iron and zinc status pose a serious threat to the physical and mental growth of these children. Hence to curb these deficiencies necessary steps should be taken.
