Association Between Diet Quality and 20-Year Heart Failure Incidence: Findings from the ATTICA Cohort Study (2002–2022)

Background/Objectives: Diet quality is a potentially modifiable determinant of heart failure (HF), yet evidence regarding its long-term association with HF incidence remains limited. This study examined the association between baseline diet quality and 20-year incident HF in the population-based ATTICA cohort.

Methods

Among 3042 adults free of cardiovascular disease at baseline (2001–2002), HF status was available for 2159 participants in 2022, of whom 241 (11.2%) developed HF. Diet quality, including the relative contributions of healthy and unhealthy food groups, was assessed using the Global Diet Quality Score (GDQS), derived from a validated food-frequency questionnaire. Logistic regression models were sequentially adjusted for age, sex, body mass index, education, physical activity, smoking burden, hypertension, diabetes, and hypercholesterolemia.
