Abstract

Anaemia iron deficiency on girl adolescent still be a nutrition problem in the world, especially in development countries. There is supplementation iron program in Mataram to decrease prevalence anaemia on girl adolescent but it is have not success yet. Adolescent girl is high risk of anaemia, because they have menarche, high requirement of iron as element to growth, and mostly low consume micronutrient because of bad food consumption. Zinc helps iron to form haemoglobin by makes transferrin for transport iron to the place that needs. Anaemia have bad effect for physical fitness, because to doing something we need enough haemoglobin to bind O2. Iron and zinc are important things for haemoglobin and physical fitness of human. The purpose of this study was to analyze the effect of iron suplementation and iron plus zinc suplementation on haemoglobin and physical fitness of girl adolescent. This study is randomized true experimental study using pre test post test control group design with a double blind of treatment. The research population is all girl students of class X and XI SMKN 8 Mataram with criteria inclusive are aged 15 until 18 years, not obesity, Hb < 12 mg/dl, and not sick. Subjects chosen by randomized simple sampling (n = 28) in two groups, control group received 15 mg iron plus placebo and treatment group received 15 mg iron plus 15 mg zinc for 12 weeks intermittent day supplementation. The results showed that supplementation with iron or iron plus zinc significantly improved haemoglobin rate (p = 0,000 for each group) and IKB or physical finess (p = 0,002 for control group and p = 0,001 for treatment group). For haemoglobin, the effect of suplementation is no diferrence significantly between control and treatment group (p = 0,275) and for physical fitness there is difference of both groups (p = 0,001). Although no difference by statistic test, the change of haemoglobin rate is difference of both groups in fact. Treatment group�s increasing rate is higher than control group in haemoglobin and physical fitness. It was concluded that by added zinc to iron supplementation can be increase the Hb rate and physical fitness more higher than iron supplementation without zinc. For anemic adolescent, they need enough iron supplementation because the difference of increasing Hb rate is no significan between added zinc or not. With such efforts, it suggests to need nutrition education program to follow iron supplementation.
