Name	Time	Method
Overweight and obesity prevalence in a representative sample of primary schoolchildren aged 10-12 years old	8 months	Assessment of overweight and obesity by measuring body weight and standing height. Body mass index was calculated by dividing weight (kg) by standing height squared (m2). Obesity and overweight among children were calculated using the International Obesity Task Force (IOTF) age and gender specific body mass index cut-off criteria

Secondary Outcome Measures
