Methods A total of 1 578 children and adolescents were randomly selected from Yinchuan city by cluster sampling from 2017 to 2020, and conducted questionnaire survey. Their physical examination and bone mineral content were measured. The relationship between obesity of different definitions and bone mineral content was analyzed by binary Logistic regression. Results BMC of obese children at different body mass index (BMI), waist circumference (WC), waist height ratio (WHtR) and percentage of body fat (FMP) groups were significantly higher than that of normal group (P<0.01). There was a positive correlation between BMC and different obesity indicators in boys and girls (P <0.01). WC in boys and BMI in girls had the highest correlation with BMC (r=0.749, 0.684). Binary Logistic regression analysis showed that after adjusting for age, it was found that obesity defined by FMP and WHtR was significantly associated with the increase of BMC in boys (FMP:OR=1.53, 95%CI:1.04 - 2.27; WHtR:OR=4.39, 95%CI:1.55 - 12.44). For girls, obesity defined by FMP was significantly associated with the increase of BMC (OR=3.46, 95%CI:1.59 - 7.51). Conclusion Obesity defined by FMP and WHtR have a certain public health value for children and adolescents to prevent osteoporosis, but excessive obesity may cause bone injury. %U https://manu41.magtech.com.cn/Jwk_zgetbjzz/EN/10.11852/zgetbjzz2021-0822
