Abstract

Abstract: Background: Childhood obesity is an important public health issue worldwide and includes different risk factors, such as environmental pollutants exposure or physical activity. Neighborhood composition and green spaces availability could contrast obesogenic lifestyles and promote healthy habits, whereas, urbanization and traffic volume exposure are inversely associated with physical activity and worsen effects on childhood health. Methods: This project analyzed students involved in the HBSC survey from the Piedmont Region. Data were collected in 2018, following the protocol. All the subjects were georeferenced within buffers around schools. Green-spaces availability was measured by Normalised Difference Vegetation Index (NDVI-satellite images) while urbanization was calculated by population density, traffic intensity (satellite measurements) and air pollution concentration (sampling stations). Results: Overall, the sample included 3022 subjects, with amount 50% male/female and 30% for each age group (11-13-15 years old). Concerning weight status, above 14% of the all sample is obese or overweight, with, respectively, 20% among boys and 11% among girls. Preliminary analyses showed an association between weight status and population density (rural vs urbanized areas). Currently, we are analyzing the association with greenness and the other measures of urbanization. Conclusions: Our preliminary findings suggest that high urbanization levels impact health implementing weight in children. We are testing the hypothesis that greenness positively influences weight status and reduce negative effects of urbanization and air pollution. The managing of these risk factors must be deepened and corroborated by active preventive Public Health strategies for improving children health. Key messages: Urbanization and greenness may influence weight status in children. Public Health strategies must be improved for children health.
