Body mass index and waist-to-height ratio among schoolchildren with visual impairment: A cross-sectional study.

A relationship which approached significance was observed between distribution of WHtR ≥ 0.50 and age of the study groups (ch 2 = 5.67; P = 0.60; phi = 0.20); the prevalence of AO observed in the various age groups was as follows: 7 to 9 years: 30% (N = 6); 10 to 13 years: 40.5% (N = 17); ≥14 years: 30.3% (N = 16).
