Results The overweight and obesity rate( 25. 30%) of primary and secondary school students in Pudong New Area exceeded the national average level. In primary school group,male,sleep time ≥ 8h per day,water intake ≥1 200 m L per day,and the presence of mobile food stalls around the school were the risk factors for overweight and obesity. Daily extracurricular exercise time of 30 minutes to 2 hours was a protective factor. In junior high school group,male and electronic product use time of ≥ 2h per day were the risk factors for overweight and obesity. The daily extracurricular exercise time of 1 to 2 hours was a protective factor. In high school group,drinking water ≥1 200 mLper day was a risk factor for overweight and obesity.
