Evaluation of Dietary Niacin and New-Onset Hypertension Among Chinese Adults

Abstract

Key Points Question Is there an association between dietary niacin intake and the risk of new-onset hypertension? Findings In this nationwide cohort study, a J-shaped association was found between dietary niacin intake and new-onset hypertension in Chinese adults, with an inflection point at about 15.6 mg/d and minimal risk between 14.3 and 16.7 mg/d of dietary niacin intake. Meaning The results of this study provide evidence that maintaining optimal dietary niacin intake levels may support the primary prevention of hypertension.
