The present study aims to explore the association between ideal diet behaviours recommended by the American Heart Association (AHA) and hypertension in the United States (US) adults using data from the National Health and Nutrition Examination Survey (NHANES) 2013–2014.
Whole grains, fruits and vegetables, fish, sodium and sugar-sweetened beverages at an ideal level were defined as the AHA's recommendation. Associations between number of ideal diet behaviours and hypertension were assessed through multivariate logistic regression models.
A total of 4462 US adult participants (2110 men and 2352 women) were included in the analysis, of whom 1516 (34.0%) were diagnosed with hypertension. The multivariate adjusted odds ratios and 95% confidence intervals (95% CIs) for hypertension in the groups with one, two and at least three ideal diet behaviours were 0.88 (0.71–1.10), 0.89 (0.70–1.12) and 0.67 (0.49–0.91), when the group with 0 ideal diet behaviour was used as the reference. Results also showed that women with three or more ideal diet behaviours had 43% (95% CI: 10–64%) lower odds of hypertension.
The number of diet behaviours at the ideal level recommended by the AHA was inversely associated with hypertension in US adults.
