Abstract

BackgroundAs it is difficult to know the content of iron added in the Brazilian iron fortification of wheat and corn flour, and if the compound has good or poor bioavailability, the objective was to assess the effect of the Brazilian iron fortification program, as it was carried out, on iron nutritional status of adolescents, 6 years after its implementation.

MethodsA cross-sectional retrospective study was conducted with adolescents aged 10 to 17 years, both sexes, treated at a primary health care center. Data were collected from medical records of patients and compared with those of a previous survey conducted at the same center in 2004. Anthropometry, iron biochemical indicators, food intake, pubertal stage, and transferrin saturation were assessed, with pubertal stage and transferrin saturation being the last two variables compared between 2004 and 2010. Mann-Whitney and chi-square tests were also used.

ResultsIn 2010, mean hemoglobin values and serum ferritin levels were within normal ranges for both sexes, and adolescents who consumed diets with low iron bioavailability constituted more than half of the sample 52.7%. In 2004, a 10.3 and 18.6% prevalence of iron deficiency was observed, based on low transferrin saturation, in females and males, respectively. It was noted that during the 6-year period, this prevalence decreased significantly, 4 and 10.4%.

ConclusionsAnemia and iron deficiency are not prevalent in this population, probably due to the implementation of flour fortification with iron; it is not possible, however, to attribute such a result only to the implementation of this strategy.
