Résumé : 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 6-18y. 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 (10-19y) 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 (6-9y) than in adolescents (10-18y) 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.
