The association between retinal artery to vein ratio and fat distribution: a population-based cross-sectional study.

ABSTRACT:

Objective

This study aims to investigate the association between the retinal artery to vein ratio (AVR) and body fat distribution, and to further evaluate the potential beneficial effects of optimized fat distribution on systemic vascular health.

Methods

A total of 2,698 participants aged 18 to 80 from Lanxi cohort were enrolled. After applying inclusion and exclusion criteria, 2,045 participants were retained for the final analysis. Retinal vessel images were obtained through fundoscopy, and retinal AVR was automatically calculated using a clinically validated AI algorithm. Body fat was assessed by dual-energy x-ray absorptiometry (DXA). Adjusted multivariate linear regression models were used to identify the associations of retinal AVR with fat distribution.
