To evaluate the nutritional status of iron and its related factors in children 12 to 15 months assisted in Health Units in Goiânia, Goiás. METHODS: This is a cross-sectional study nested in research "Effectiveness of home fortification with vitamins and minerals in the prevention of iron deficiency and anemia in children under one year of age: a multicenter study in Brazilian cities ". The study was conducted with 230 children, aged between 12 and 15 months, assisted in Health Units in Goiânia, from June 2012 to February 2013. The prevalence of iron deficiency, iron deficiency anemia and anemia were assessed by the plasma means concentration of ferritin and transferrin receptor, hemoglobin and C-reactive protein. Multiple linear regression was used to estimate the effect of independent variables on the log plasma concentrations of ferritin. These variables were socioeconomic, demographic, maternal, pregnancy, anthropometric, breastfeeding, use of supplement, and biochemical parameters. RESULTS: Regarding the iron status, iron deficiency and iron deficiency anemia prevalence was 14.1% and 1.5%, respectively. Also, anemia prevalence was 5.6% of the infants studied. The predictors of ferritin were folate, vitamin B12 and the use of iron supplement at the time of collection, which each unit raised the log plasma concentration of ferritin in 0.009 mg/L, 0.001 mg/L and 0.315 mg/L, respectively. CONCLUSION: The results of this study showed low prevalence of iron deficiency and anemia in children studied. The use of iron supplements and serum concentrations of vitamin B12 and folate correlated ferritin concentrations and consequently the iron status in this population.
