Dietary Polyphenol Intake and Risk of Hypertension: An 18-y Nationwide Cohort Study in China.

ABSTRACT:

Background

Although increasing evidence suggests that polyphenol helps regulate blood pressure (BP), evidence from large-scale and long-term population-based studies is still lacking.

Objectives

This study aimed to investigate the association between dietary polyphenol and hypertension risk in the China Health and Nutrition Survey (N = 11,056).

Methods

Food intake was assessed using 3-d, 24-h dietary recalls and household weighing method; polyphenol intake was calculated by multiplying consumption of each food and its polyphenol content. Hypertension was defined as BP ≥ 140/90 mmHg, physicians' diagnosis, or taking antihypertension medications. HR and 95% CI were estimated using mixed-effects Cox models.

Results

During 91,561 person-years of follow-up, a total
