Food consumption patterns and high blood pressure levels among Brazilians: cross-sectional study, 2013

Abstract

Objective. To analyze the association between patterns of food consumption markers with high blood pressure levels among Brazilians. Methods. Cross-sectional study with data from the National Health Survey, with outcome high blood pressure levels, measured during an interview, between August and November 2013. Food patterns, the exposure variables, were identified. Prevalence ratio (PR) and 95% confidence interval (95%CI) were calculated using multivariable Poisson regression. Results. The prevalence of high blood pressure levels was 16.0% (95%CI – 15.3;16.7) of the 37,216 participants, being higher in those with a diet that included meat and alcoholic beverages (PR=1.21 – 95%CI 1.08;1.35). The pattern with highest presence of greens and vegetables did not show a statistically significant association com níveis pressóricos elevados (PR=0.94 – 95%CI 0.84;1.06). Conclusion. The pattern with meat and alcoholic beverages was associated with high blood pressure levels.
