Diet quality and the risk of cardiovascular disease: the Women's Health Initiative (WHI).

ABSTRACT:

Background

The association between diet quality and risk of incident cardiovascular disease (CVD) or heart failure (HF) in postmenopausal women is uncertain.

Objective

This study aimed to determine whether a conventional index [Alternate Healthy Eating Index (AHEI)] or a novel index [Women's Health Initiative (WHI) Dietary Modification Index (DMI)] of diet quality was associated with the risk of incident CVD or HF in the WHI Observational Study (WHI-OS).

Design

The WHI-OS is an observational cohort study of 93,676 women aged 50-79 y of diverse ethnicity and backgrounds followed for an average of 10.0 y for CVD events.
