Association Between Body Composition and Retinal Vascular Caliber in Children and Adolescents

Abstract

PURPOSE: To elucidate the relationship between body composition and retinal vascular caliber (RVC) in children and adolescents. METHODS: Participants aged 7 to 19 years were recruited from the Guangzhou Twin Eye Study cohort. Retinal vascular caliber was measured cross-sectionally from retinal images using a computer-aided program. The data were expressed as the central retinal arteriolar equivalent (CRAE) and central retinal venular equivalent (CRVE). Triceps skinfold thickness (TSFT) was measured using a skinfold caliper. Body composition was obtained through bioelectrical impedance analysis, providing fat mass (FM), fat mass index (FMI), fat-free mass (FFM), fat-free mass index (FFMI), bo..
