Prevalence of Micronutrient Deficiencies among Preschool and School-Going Children in Flood-Hit Areas of Pakistan.

There is minimal literature regarding micronutrient deficiencies in flood-affected regions. In our study, we aimed to find the prevalence of micronutrient deficiencies (vitamin A, calcium, zinc, iron, and iodine) among preschool and school-age children in flood-hit areas of Khyber Pakhtunkhwa, Pakistan. In this cross-sectional study, a multi-stage sampling technique was used for the selection of 656 households. Serum micronutrient status was detected in the targeted population in the affected districts. The least significant difference test was used with analysis of variance to determine significant differences in nutrient contents in different areas. Of the total respondents, 90.8% of the children were calcium deficient, 88.3% were zinc deficient, 26.7% were iron deficient, 53.5% were vitamin A deficient, and 39.5% were had an iodine deficiency in flood-affected areas. A significant difference (P < 0.05) was found in different age groups of children for zinc (5.7-42.63 μg/dL) and urinary iodine (69.6-85.4 μg/L). The 10- to 12-year-old age group had a lower serum zinc concentration (5.7 μg/dL), whereas the 1- to 3-year-old age group had a lower urinary iodine concentration (69.6 μg/L) than other groups. There was no significant difference (P > 0.05) between male and female children and various age groups for calcium and iron status. Vitamin A levels were significantly (P < 0.05) different among different age groups (high in age group 4-6 years) and districts. Vitamin A concentration was lower in the Nowshera District, whereas serum iron and zinc were lower in the Dera Ismail Khan District. All the important micronutrients in the population of children were deficient in the flood-affected areas of Pakistan. Therefore, policymakers should implement potential prevention strategies, such as food security, school health nutrition, food fortification, nutrition in the first 1,000 golden days, nutrition knowledge, and awareness of the local population, to reduce the burden of micronutrients deficiencies in flood-affected areas.
