Body mass index and its effects on retinal vessel diameter in 6-year-old children

Abstract

PURPOSE: To examine the relationship between body mass index (BMI) and other anthropometric measures with retinal vessel diameter in children. METHODS: A random cluster sample of 34 schools was selected in the Sydney metropolitan area during 2003-04, and 1740 children aged 6 years participated in The Sydney Childhood Eye Study. Retinal images were taken and vessel diameter was measured using a computer-imaging program. Anthropometric measures, including weight, height, waist circumference, BMI and body surface area (BSA), were obtained and defined using standardized protocols. Data on confounders, including ocular parameters, ethnicity, birth parameters and blood pressure, were similarly col..
