Backgrouds: Prevalence of stunting in children under five years in 2007 was 36.8%, then in 2010 decreased to 35.6%. The percentage again increased to 37.6% in 2013. The prevalence of stunting tend to increase nationally
One form of nutritional services for individuals is nutritional supplementation. Supplementation of zinc is recommended to overcome growth problems in children . Administration high doses of vitamin A should also be followed by zinc supplementation. Vitamin A and zinc are in relation in the absorption process of the two as well. In a state of vitamin A deficiency, it decreases zinc-binding proteins while vitamin A deficiency lead to impaired absorption of zinc (Agustian, 2009).
Zinc plays a role in metabolism and transport of vitamin A as well as in the synthesis of protein transport retinol (PTR), such as hepatic cell PTR (CPTR) which is an intracellular protein transport retinol in the liver cells and holo PTR that brings retinol from the liver into the blood stream and other tissues (As anti,2013)
Objectives : To determine the effect of zinc supplementation in stunting children after administration of high dosage of vitamin A to the nutritional intake, biochemical and anthropometric status.
Methods: This study used pre- and post-control study design. The study was conducted for a month, with supplementation of zinc syrup as much as 10 mg/ day to stunting children aged 2-4 years, after administration of high dosage of vitamin A. Sample size was 45 individuals, that was divided into 3 groups: zinc, vitamin A and zinc + and vitamin A. Indicators under measurements were intake of energy, intake of macro nutrients that included carbohydrates, fats and proteins, biochemical status such as zinc, albumin, total protein and hemoglobin as well as anthropometric indexes; weight/age, height/age and weight/height.
Results: zinc supplementation followed by supplementation of high-dosage of vitamin A in stunting children was effective to improve biochemical status and while the same treatment was not effective to improve the intake of energy and macro nutrients and anthropometry.
Keywords: zinc supplementation, high-dosage of vitamin A, stunting, nutritional intake, biochemical, anthropometric.
