title: [Detection rates of overweight and obesity in children and adolescents with different ethnicities in Xinjiang Uigur areas].
abstract: OBJECTIVE
  To investigate the detection rates of overweight and obesity among Han,Uygur and Kazakh Children and adolescents in Xinjiang.
  
  
  METHODS
  Random samples were used to analyze the detection rates on overweight and obesity based on data from Han,Uygur and Kazakh Children and adolescents aged 7-14 years from 3 regions-Hetian, Kashi and Fuhai prefectures in Xinjiang Uygur Autonomous Region. Anthropometric data including weight and height was collected. Overweight and obesity were defined according to body mass index [BMI, weight (kg)/height (m²)] cutoffs recommended by the Chinese Working Group on Obesity for Children (WGOC)aged 7-14 years.
  
  
  RESULTS
  The present study was performed in 11 894 Han, Uygur and Kazakh Children and adolescents aged 7-14 years. The overall prevalence rates of overweight and obesity were 5.6% and 2.9% respectively, which the difference between male and female was significant (χ² = 39.765, P < 0.05). Different ethnic students of overweight and obesity rate showed differences, with detection rate of overweight among Kazakh students was 12.0% , higher than the other ethnic groups. The obesity detection rate was 7.2% among Han students, which was the highest of the three ethnic groups, with differences statistically significant(χ² = 363.885, P < 0.05). Prevalence rates of both overweight and obesity decreased with increasing age in various ethnic groups, showing a clear downward trend, with the peak at 7-9 year-olds and the difference was statistically significant(χ² = 101.479, P < 0.05).
  
  
  CONCLUSIONS
  Both detection rates on overweight and obesity among children and adolescents were significantly lower in Xinjiang Uygur Autonomous Region than the national average level, with differences also seen in different ethnic, gender and age groups.
