1 Variables with normal distribution are presented as mean ± SD, and variables without normal distribution are presented as median and interquartile range. 2 MNP = Multiple micronutrients powder. 3 FS_FA = Ferrous sulfate and folic acid. 4 Pearson’s chi-square test/Fisher’s exact test for categorical variables; Student’s t test for continuous variables with normal distribution and Mann–Whitney U test for continuous variables without a normal distribution.5 Economic class was defined by the ABEP (Brazil economic classification criterion) criterion. A or B: upper income status; C, D, or E: lower income status. 6 1 US = R$ 3.44 at the time of data collection.
