abstract: OBJECTIVE
  To understand the status and associated factors of overweight and obesity of rural children under 7 year-old in Gansu province.
  
  
  METHODS
  A total of 9390 rural children under 7 year-old and their mothers in 4 counties in Gansu province were selected by stratified random cluster sampling method and screened for overweight or obesity by BMI. All data were input by using a double entry method with EPI data 3.0 software and analyzed statistically by Excel/SPSS 10.0 software.
  
  
  RESULTS
  The detection rate of overweight in rural children under 7 in Gansu province was 8.2% (male 8.7%, female 7.9%), the detection rate of obesity was 6.1% (male 6.4%, female 5.8%). The independent risk factors for overweight and obesity were birth weight > or = 4000 g and living in scattered lifestyle.
  
  
  CONCLUSIONS
  The risks of overweight and obesity in rural children are rather high, more attention should be paid to children aged from 9 month to 2 years. Reducing the rate of birth weight > or = 4000 g and scattered lifestyle in children can make some contribution to the prevention of obesity and overweight.
