A Cohort Study of Air-Pollution and Childhood Obesity Incidence (303436)
*Xiaoyi Zhou, University of Southern California"Background: Traffic-related air pollution could active the metabolic disorders through inflammatory pathways, potentially leading to obesity. Here we sought to determine whether air pollution have positively association with obesity incidence in children aged 8–18 years. Methods: 3,887 children aged 8-12 were selected with height and weight measured annually. Overweight and obesity were calculated with an age and sex-specific BMI. Average annual ambient exposure was estimated from data collected at monitoring stations in each communities. Dispersion models were used to estimate exposure to traffic-related air pollution. Proportional hazard regression and logistic regression were used to test ambient and traffic pollution related to obesity incidence and prevalence. Results: Some of the ambient air pollution exposures were significantly positively associated with obesity incide. There is no findings of the association between traffic air pollution and obesity incidence. Conclusions: More researches should be done for association between air pollution and BMI growth and/or attained BMI at a certain age."
