Zinc deficiency: descriptive epidemiology and morbidity among preschool children in peri-urban population in Delhi, India.

Dhingra U, Hiremath G, Menon VP, Dhingra P, Sarkar A, Sazawal S - J Health Popul Nutr (2009)

Bottom Line: Community-based data relating to factors influencing zinc deficiency among preschool children in India are inadequate.Of these children, 116 from the control group belonging to the upper and the lower 25th quartile of plasma zinc status at baseline were selected for assessing the association of zinc deficiency with prospective morbidity.A significantly higher risk of morbidity was prevalent among the subjects with lower plasma zinc compared to those with higher levels of plasma zinc.

ABSTRACT
Community-based data relating to factors influencing zinc deficiency among preschool children in India are inadequate. Data of a large, double-blinded, randomized, controlled zinc-supplementation trial were used for assessing the descriptive epidemiology of zinc deficiency among children aged 6-35 months (n = 940). In total, 609 children were followed up for 120 days for information on morbidity. Of these children, 116 from the control group belonging to the upper and the lower 25th quartile of plasma zinc status at baseline were selected for assessing the association of zinc deficiency with prospective morbidity. At baseline, demographic, socioeconomic and dietary information was collected, and anthropometric measurements and levels of plasma zinc were assessed. At baseline, 73.3% of the children were zinc-deficient (plasma zinc < 70 microg/dL), of which 33.8% had levels of plasma zinc below 60 microg/dL. A significantly higher risk of morbidity was prevalent among the subjects with lower plasma zinc compared to those with higher levels of plasma zinc.

Figure 2: Comparison of prevalence of zinc deficiency among children with acute diarrhoea and those without diarrhoea

Mentions: The descriptive epidemiology of zinc deficiency is presented in Table 2. The children in the cohort were categorized into three quartiles based on levels of baseline plasma zinc. The nutritional status, breastfeeding status, recent intake of dietary zinc-rich food(s), including the consumption of non-breastmilk, and socioeconomic level among children were similar across the quartiles. Diarrhoeal and respiratory morbidity was similar among the quartiles. C-reactive protein was positive in only 0.1% of the children. The prevalence of zinc deficiency among children having acute diarrhoea at baseline was similar to those without diarrhoea at the end of the study (Fig. 2).
