Height and weight were measured (body mass index was consequently calculated). Results:The prevalence of eating out among Chinese children aged 6-17 years old was 23.2%. Children who ate out 0, 1-2, ≥3 times per week were accounted for 76.8%, 10.9% and 12.3% respectively. Findings revealed that eating out three times per week or more was statistically significant associated with higher prevalence of overweight and obesity among boys (OR=1.20,95CI:1.04-1.38) compared with those ate out less than three times per week. However, no significantly association was observed among girls (OR=0.91, 95CI:0.78-1.01). In additional, Younger children, rural children, children from low income family, those with leisure exercises (certain physical activities regularly carried out such as swimming, walking, running, equipment fitness), leisure time sedentary behaviors (LTSB)(>2h/d) were relatively more likely to eat out.
