Abstract
Background: There is conflicting evidence regarding the role of salt intake in blood pressure (BP). Aim: To estimate the impact of salt consumption on the BP level of a non-hypertensive population aged between 15 and 64 years. Material and Methods: Analytical-observational study using data from the National Health Survey 2009-2010. A BP cut-off point at 120/80 mmHg BP was considered to determine risk. Salt consumption was divided into four strata. The prevalence ratios (PR) were determined using the Poisson model with robust variance. The formulas of the studies of Dal Grande and Walter for the estimation of population attributable fraction (PAF) were used. Results: The sample was constituted by 1,263 individuals and 24.3% had BP at risk. A statistically significant association was observed between high salt intake and risk BP with PR of 1.91 (95% confidence intervals (CI) 1.44-2.57) in the consumption stratum of 11 g / day and more. It was estimated that 4.7% (95% CI 4.2-5.2) of BP risk can be attributed to salt consumption, when controlling by age group, sex and educational level. Conclusions: The 4.7% PAF is lower than the figure of 30% reported abroad. Interventions to reduce salt consumption in the entire population and the identification of risk groups are recommended.
