Abstract:
Brazilian national strategies for the control of anemia and vitamin A deficiency in children are based on estimates of their nationwide prevalence rates in 2006 with methods not validated for this age group and with disaggregation at the level of major geographic regions. To back local administrations in (re)directing control measures for these two disorders, the current study presents estimates of their prevalence and markers of dietary intake of sources of micronutrients and use of vitamin and mineral supplements in a probabilistic sample of children 6 to 59 months of age, users of primary healthcare in the city of Rio de Janeiro, Brazil (n = 536). Venous blood samples were drawn for analysis of hemoglobin, ferritin, and serum retinol, besides collection of data on food consumption, use of vitamin and mineral supplements, and sociodemographic characteristics. Prevalence rates for anemia, iron deficiency anemia, and vitamin A deficiency were 13.7%, 5.5%, and 13%, respectively. Nearly all the children had consumed iron-rich food the day before the interview, with high prevalence of animal sources. Only 49.4% had consumed foods high in vitamin A. The prevalence rates for use of any supplement, iron supplements, and vitamin A supplements were 51%, 14.7%, and 24.4%, respectively. The findings point to the need to redirect the strategies for prevention and control of anemia and vitamin A deficiency. Future studies are necessary to examine trends in these indicators, focusing on austerity policies implemented in recent years and the economic crisis resulting from the COVID-19 pandemic.
