Objective: To evaluate the mean urinary sodium excretion and its difference by sex by Kawasaki and Tanaka equations in an isolated urine sample in afro-descendants from Alcântara-MA. Material and Method: Cross-sectional study, conducted between August 2012 and August 2013, with collection of demographic, socioeconomic, lifestyle, blood pressure measurement, blood and urine samples. Results: Female predominance 51.20%, men were younger 31.57% and 74.78% had less than eight years of schooling, 99.56% belonged to social classes D and E. 56.11% received less than one minimum wage, 10.89% smoked and 53.01%, (p-value <0.001), did not consume alcohol or had stopped. The mean urinary sodium excretion in an isolated sample for the Kawasaki equation was 203.2 mmol/L ± 84.9 mmol/L and 150.7 mmol/L ± 47.3 mmol/L for the Tanaka equation. The difference in the estimation of sodium excretion between both was 52.5 mmol/L ± 40.5 mmol/L. Conclusion: In this study, the Kawasaki equation presents higher mean excretion values when compared to the Tanaka equation; however, the Tanaka equation tends to underestimate the mean excretion value for men.
