Resumo
Objective: This study aimed to assess the nutritional status of vitamin A and associated factors in
children assisted in Primary Care Health in Goiânia, Goiás, Brazil. Methods: This is a cross-sectional study with
a sample of 228 children 12 to 16 months of age. The nutritional status of vitamin A was assessed by serum
retinol concentration, determined by high performance liquid chromatography. Multiple linear regression
models with hierarchical selection of independent variables were used to evaluate the correlation with serum
retinol as the dependent variable. Results: The vitamin A deficiency (retinol < 0,7 μmol/L) was observed in
14,0% of the children. Maternal schooling and hemoglobin concentration were positively correlated with serum
retinol concentration, while C-reactive protein showed a negative correlation (R2
= 0,1648). Conclusion: The
vitamin A deficiency in one-year-old children attended in Basic Health Units in Goiânia configures itself as a
moderate public health problem. Actions to promote maternal education, morbidity control and prevention
of other micronutrient deficiencies are important for prevention and control of the vitamin A deficiency in
this population
