[Comparative study on different overweight reference applied on analyzing growth of Chinese children and adolescents]

The paper is studied based on anthropometry data collected in 1991 and 2000 in the China Health and Nutrition Survey, which is collaboration with the University of North Carolina at Chapel Hill. The sample are 7-18 years old children and adolescents. The primary purpose of this paper is to study the trends and prevalence of overweight and obesity among Chinese children and adolescents with different references and to compare the results and to further discuss their strengths and limits. The results from all the references indicate that overweight among Chinese children and adolescents are increasing sharply and becoming a problem that can't be overlooked. These references are not quite suitable for Chinese children and adolescents. Native age-sex-BMI references of overweight and obesity among Chinese children and adolescents should be established.
