The outcomes which were secondary were variations in BMI, body weight, hip and waist circumference, and ratio of waist-to-height. An intent to treat analysis was accomplished. Results: 80 children were randomly assigned to the control group or 80 in the treatment groups. Children who took multivitamins along with zinc had a greater height increase ((4.5±5.1 vs 3.5±4.1 cm, correspondingly; 0.001 of P value). Subgroup analysis exhibited substantial height improvement, particularly among preadolescents. The greatest increase in height occurred regardless of the initial weight and height. An additional increase in growth is visible subsequently two months of supplement. Variations in the other anthropometrical measures did not differ substantially.
