Children's health and outdoor activities are closely related, with the increasing of childhood obesity and the improvement of people's health consciousness, urban planning and spatial design promoting children's outdoor activities will become increasingly important. Selecting children and teenagers of 6-18 years old in Shanghai as the object, this research conducts a network questionnaire survey to obtain the data and quantitatively analyzes the spatial-temporal characteristics of their health and outdoor activities. A relationship model between the children's outdoor activities and congnized neiborhood environment is established, using the logistic regression model. Results show that children in shanghai have a high incidence of obesity and are lack of outdoor activities. The time of outdoor activities is concentrated in the daytime of weekends, and the activity venue is concentrated in the green lands and exercise fields in the community or the parks nearby. Children's vigorous activities tend to happen with high time consumption and frequency in the vacant street space and sidewalks along the street. At the city level, some parts of Shanghai can see remarkably high concentration or low concentration of children's outdoor activities, and the frequency and time consumption of children's vigorous activities within the Inner Ring is significantly higher than that in other rings. Neighborhood environmental factors have significant associations with children's health and outdoor activities. Curb parking, environmental harmony and civilization, neighborhood relationship, and the quality of children's activity facilities have a significant correlation with children's outdoor activities, especially with their activity frequency.
