Description
Summary:Background and Aims A high dietary sodium intake and a low potassium intake are associated with adverse cardiovascular health. Data on these nutrients consumption in Mexico is limited. The aim of this study was to assess sodium and potassium intake by 24 h urinary excretion in a clinically healthy Mexican population. We additionally explored their association with blood pressure. Methods 711 clinically healthy participants aged 20–50 years old recruited in the Tlalpan 2020 cohort from September 2014–December 2015, were included in this cross-sectional analysis. All participants provided a 24 h urine sample and underwent anthropometric, biochemical, and blood pressure evaluations. Univariate and multivariate linear regression analyses were used to assess the association of urinary sodium, potassium, and Na/K ratio with blood pressure. Results Mean (95% confidence interval [CI]) urinary sodium and potassium in the overall population was 3150.1 (3054.2–3246.0) mg/d and 1909.5 (1859.3–1959.6) mg/d, respectively. Overall, only 121 (17%) met the WHO recommendation for sodium intake (
