title: [Prevalence on overweight and obesity in Han, Uygur and Hazakh in adults from Xinjiang].
abstract: OBJECTIVE
  To investigate the prevalence and distributing feature of overweight and obesity in Han, Uygur and Hazakh population in adults from Xinjiang.
  
  
  METHODS
  Four-stage selected random samples with maternal age at 35 or over were used to analyze the prevalence and distributing feature of self-reported congestive heart failure in different nationalities, age, sex. The sampled adult population were collected from 6 localities (Urumqi, Kelamayi, Fukang, the Turfan Basin locality, Hetian locality, Yili Hazakh autonomous prefecture), 23 municipalities and 7 locality and 5 autonomous counties in Xinjiang.
  
  
  RESULTS
  16 460 people were surveyed. The prevalence rates of overweight and obesity were 36.1% and 26.9% in Han, Uygur and Hazakh population in Xinjiang, respectively from February, 2007. The prevalence rates of overweight and obesity were 41.4% and 18.4% in Han population, 34.9% and 28.9% in Uygur population, but 32.8% and 40.1% in Hazakh population. The prevalence rate of overweight and obesity was higher in males (χ(2) = 135.00, P < 0.05). The prevalence rates of overweight and obesity were different between different ethnic groups (χ(2) = 338.232, P < 0.05). The prevalence of overweight was highest in Han population, with the highest seen in Hazakh population. The prevalence rates of overweight and obesity were increasing with age (χ(2) = 246.80, P < 0.05). The overweight rate in 45-54 year olds and the obesity rate in 55-64 year olds reached their peak values. Results from logistic regression model analyses indicated that the prevalence of overweight and obesity in Xinjiang were statistically associated with age, educational level, jobs, smoking and alcohol consumption.
  
  
  CONCLUSIONS
  The prevalence rates of overweight and obesity were much higher in the population of Xinjiang but different among ethnicities. The prevalence of overweight was the highest in Han male population and the rate of obesity in Hazakh male population was the highest.
