Abstract | BACKGROUND: METHODS: Using stratified cluster sampling approach, a school-based cross-sectional investigation was undertaken among 687 children and adolescents aged 8-15 years. Each participant's index finger (2D) and ring finger (4D) length, height, weight, testosterone, and estradiol levels were measured, and their dietary behaviors, physical and sedentary activities were also surveyed. RESULTS: The prevalence of overweight or obesity among children and adolescents aged 8- and 12-15 years was 36.0% and 25.9%, respectively (P < 0.05). There were no associations between 2D:4D and overweight or obesity in both boys and girls (P > 0.05). However, 2D and multiplying index of digit ratio and length (MIDRL) associated directly with overweight or obesity among boys (OR (95%CI) were 1.45 (1.00, 2.14), 1.46 (1.01, 2.11), respectively), and was indirectly related to overweight or obesity by testosterone (OR were 1.30, 1.26, respectively).
