Objective: Epidemiologic evidence concerning the role of dietary glycemic index (GI) and glycemic load (GL) in obesity during childhood and adolescence is limited, particularly in non-Western populations. We examined the association between dietary GI and GL as well as dietary fiber intake and overweight status in Japanese children and adolescents.Subjects: This Japanese cross-sectional study included 15 974 children (6-11 years; 7956 boys and 8018 girls) and 8202 adolescents (12-15 years; 3944 boys and 4258 girls).Methods: Dietary intake was assessed using a self-administered diet history questionnaire for children and adolescents. Body mass index (BMI) was calculated from self-reported body weight and height. Overweight was defined according to the International Obesity Task Force age-and sex-specific BMI cutoffs, which correspond to an adult BMI of >= 25 kgm(-2).Results: The overall prevalence of overweight was 13.2%. Mean (s.d.) dietary GI was 63.0 (3.1), mean dietary GL was 85.0 (12.4) per 4184 kJ (1000 kcal) and mean dietary fiber intake was 5.9 (1.2) g/4184 kJ. After adjustment for potential confounding factors, dietary GL was positively associated with the risk of overweight in male children, female children and male adolescents (P for trend
