Association between dietary quality and health-related quality of life among older adults: a cross-sectional study.

ABSTRACT:

Background

Dietary quality is an important lifestyle factor linked to prevention of age-related diseases and functional decline, yet its contribution to health-related quality of life (HrQoL) in later life is underappreciated. We examined the association between overall dietary quality and HrQoL among community-dwelling Korean older adults.

Methods

We conducted a cross-sectional analysis of 2,104 older adults aged ≥ 65 years from the 2019-2020 Korea National Health and Nutrition Examination Survey. Dietary quality was assessed using the Korean Healthy Eating Index (KHEI), calculated from a single 24-hour dietary recall. The participants were categorized into quintile groups according to their KHEI scores. HrQoL was measured using the EuroQoL-five dimensions (EQ-5D), analyzed
