ABSTRACT
SUMMARY OBJECTIVE The aim of this study was to describe the prevalence of anemia and iron deficiency anemia (IDA) in infants and verify the association of iron deficiency with nutritional status. METHODS This cross-sectional and observational study included 104 infants aged between 7 and 9 months, assisted from August to September 2021 by the Family Health Strategy program in Sousa municipality (Paraíba, Brazil). Clinical and anthropometric data were collected, and a 24-h food recall questionnaire was applied using the DietPro software (version 5.0) in order to verify food consumption and assess iron intake. Variables associated with iron deficiency (p<0.05) were analyzed using multiple logistic regression. RESULTS Anemia and IDA were observed in 40.4% and 19.2% of infants, respectively. Only one infant was taking prophylactic supplementation (ferrous sulfate). Infants with IDA presented reduced hemoglobin (p<0.001) and ferritin (p<0.001) and increased Z-scores of body mass index-for-age (Z-BMI) (p=0.027), weight-for-height (p=0.007), and weight-for-age (p=0.032). All Z-scores were inversely correlated with ferritin (Z-BMI [rho -0.37; p<0.001], weight-for-height [rho -0.37; p<0.001], and weight-for-age [rho -0.29; p=0.002]). Ferritin was also directly correlated with daily iron intake (rho 0.22; p=0.018). Finally, multiple logistic regression showed a significant and direct association of iron deficiency with weight-for-height Z-score (odds ratio 2.86; 95% confidence interval 1.38-5.64; p=0.004). CONCLUSION About 60% of infants presented anemia or IDA. Iron deficiency was associated with the weight-for-height Z-score, showing the vulnerability of infants during the introduction of complementary feeding.
