ABSTRACT Objectives The digit ratio (2D:4D) is a possible marker of prenatal hormone exposure. The purpose of this study was to explore the relationships between digit ratio (2D:4D) and anthropometric indexes in Chinese children and adolescents. Methods This study is a cross‐sectional study. A school‐based survey among 685 children and adolescents aged 8–15 years were conducted by stratified cluster sampling. The length of index finger (2D) and ring finger (4D) of the left hand, height, sitting height (ST), weight, chest circumference (CC), waist circumference (WC), hip circumference (HC), and abdominal skinfold thickness (AST) were measured. Pearson correlation and multivariate linear regression were used to analyze associations between 2D:4D and above indexes. Results In girls, 2D:4D was positively related to WC, AST, waist‐to‐height (WHtR), waist‐to‐hip ratio (WHR) after adjusting for ages ( p 0.05). Conclusions The 2D:4D was related to anthropometric indexes in girls, which suggests that the maternal prenatal hormone exposure might be related to the anthropometric indexes of their female offspring.
