AB  - OBJECTIVES: To determine which set of BMI cut-offs is the most appropriate to 
      define child and adolescent obesity in urban China. DESIGN: A cross-sectional 
      study was carried out between 1 November and 31 December in 2017. SETTING: 
      Community Healthcare Center in Minhang District, Shanghai, China. PARTICIPANTS: A 
      total of 12 426 children and adolescents aged 7-17 years were selected by cluster 
      random sampling. Bioelectrical impedance analysis was the gold standard to 
      measure body composition. RESULTS: Comparisons of three sets of BMI cut-offs by 
      sensitivity and kappa value revealed that the Working Group on Obesity in China 
      (WGOC) (sensitivity 39.9-84.0 %; kappa 0.51-0.79) and WHO (sensitivity 25.5-74.5 %; kappa 
      0.35-0.78) cut-offs were not superior to the International Obesity Task Force 
      (IOTF) (sensitivity 47.9-92.4 %; kappa 0.58-0.85) cut-offs across all subgroups. The 
      WGOC and WHO cut-offs yielded higher misclassification rates, in the worst case, 
      categorising 11.2 % of girls with high adiposity as normal and 44.4 % of them as 
      overweight, while the IOTF cut-offs categorised 2.3 % as normal and 30.7 % as 
      overweight. Individuals who were classified by the IOTF cut-offs as overweight 
      had the lowest ratios of high adiposity (4.2-41.6 %) than by the BMI cut-offs for 
      each subgroup. Among pubertal girls, none of the BMI-based cut-offs indicated 
      excellent agreement with body fat percentage, and kappa value of the WHO cut-offs 
      (0.35 (95 % CI 0.29, 0.41)) was lower than the other two sets of BMI cut-offs 
      (all P < 0.001). CONCLUSIONS: The IOTF cut-offs for Asian should be recommended 
      for child obesity screening in urban China. Pubertal individuals need a more 
      accurate indicator of obesity screening.
