Background:As in most developed countries, levels of child obesity in China are increasing dramatically while few research only focus on preschool instead of adolescence or mixture of
together that lead to deficiency clarification about the influential factors and mechanism.
Methods:Cross-sectional surveys with 306 preschool students' (aged 3-6 ) family from 3 private and 4 public kindergartens of Shanghai, China was conducted to indentify the
environment, psychosocial characteristics and behavior characteristic within social-ecological frame potential influenced commute behavior.
Results:5 factors affect the transportation physical activity. For caregiver, the model shows that children taken care by their parent was associated with 2.18 times odds (p=0.002)
more than by both parent and grandparent/baby-sister together. Hence, children taken care by their parent were more likely to walk or cycle to school. For the traffic environment, the result showed
mixture of pedestrian and motor way was 45% lower odds (p=0.01) of children walk or cycle to school, which means less mixture of pedestrian and motor way are associated with more actively commute.
Food Environment was 64% lower odds (p=0.01) and safety was 42% lower odd (p=0.04) of children to walk or cycle. In another words, more food environment and more safety problems, less likely to walk
or cycle of children occurred. Children in public school was 90% lower odds (p=0.00) to walk or cycle than in private school. Hence children in private school were more likely to commute to school
Conclusions: To localize some variables according to their country characteristic gives the important hint in public health field with different background. Some results are different
from the researches in adolescent, which indicates the factors affect actively commute differed from the age of children which will lead to different intervention taken for the population.
