Methods Based on the cross-sectional data of the survey in China completed in 6 provinces (Heilongjiang, Inner Mongolia, Ningxia, Sichuan, Yunnan and Hunan), 11 542 school-age children aged 10 to 18 were selected as the research subjects. The obesity status was classified separately or cross-classified by BMI and FMP, and the Logistic regression model was used to analyze and compare the risks of cardiometabolic risk factors. Results Without adjusting for the waist circumference (WC), the group [BMI(-)+FMP(+)] had a lower risk of elevated low high-density lipoprotein cholesterol (HDL-C) and elevated blood glucose, however, the other groups had a higher risk of obesity-related metabolic abnormalities. After adjusting for WC, the [BMI(+)+FMP(+)] group had a higher risk of high triglycerides(TG) [OR(95%CI):2.55 (1.29 - 5.02)], dyslipidemia [OR(95%CI):2.07 (1.19 - 3.61)] and elevatedfasting blood pressure [OR(95%CI):2.20 (1.29 - 3.77)] among boys. Among girls, the [BMI(+)] and [FMP(+)] group had a higher risk of dyslipidemia [OR(95%CI):2.02(1.09 - 3.74)]. Conclusion It is necessary to add FMP when assessing child obesity to screen for the risk of dyslipidemia and elevated blood pressure. %U https://manu41.magtech.com.cn/Jwk_zgetbjzz/EN/10.11852/zgetbjzz2021-1752
