AB  - OBJECTIVE: To compare different references assessing child and adolescent 
      overweight and obesity in different populations. DESIGN: Comparison 
      cross-sectional study. SETTING: The United States, Russia, China. SUBJECTS: A 
      total of 6108 American, 6883 Russian and 3014 Chinese children aged 6-18 y. 
      INVESTIGATION: Using nationwide survey data from the USA (NHANES III, 1988-1994), 
      Russia (1992), and China (1991), we compared three references: (1) the 
      International Obesity Task Force (IOTF) reference, sex-age-specific body mass 
      index (BMI) cut-offs that correspond to BMIs of 25 for overweight and 30 for 
      obesity at age 18; (2) the World Health Organization (WHO) reference--BMI 85th 
      percentiles for overweight in adolescents (10-19 y) and weight-for-height 
      Z-scores for obesity in children under 10; (3) a USA reference--BMI 85th and 95th 
      percentiles to classify overweight and obesity, respectively. RESULTS: Using the 
      IOTF reference and 85th BMI percentiles, overweight prevalence was 6.4 and 6.5% 
      in China, 15.7 and 15.0% in Russia, and 25.5 and 24.4% in the USA, respectively. 
      Notable differences existed for several ages. Kappa (=0.84-0.98) indicated an 
      excellent agreement between the two references in general, although they varied 
      by sex-age groupings and countries. Overweight prevalence was twice as high in 
      children (6-9 y) than in adolescents (10-18 y) in China and Russia, but was 
      similar in the USA. Estimates of obesity prevalence using these three references 
      varied substantially. CONCLUSIONS: The references examined produce similar 
      estimates of overall overweight prevalence but different estimates for obesity. 
      One should be cautious when comparing results based on different references.
