Impact of Micronutrient Malnutrition on the Health of Preschool Children: A Cross-Sectional Study

Abstract

Abstract. A cross-sectional study was designed to diagnose the prevalence of serum micronutrient deficiencies in apparently healthy preschool children in Pakistan. Children with any organic illnesses, abnormal blood parameters or genetic disorder were excluded. Amongst the studied samples, 56 % were healthy, 7 % were overweight, 7 % were obese, and 30 % were underweight. The body mass index (BMI) of female children was reduced compared to male children, which was statistically significant (p < 0.05). Similarly, zinc and iron deficiencies, ranging from moderate to severe, were found in 50 % and 25 % of the studied population, respectively. Copper and vitamin A concentrations were insufficient in 7 % and 25 % of the subject children, respectively. Micronutrient malnutrition is a recurrent health problem in children below the age of 5 years worldwide, particularly in developing countries. Serum micronutrient deficiencies and imbalances were more prevalent in children from rural than from urban areas.
