Objectives: Previous studies have examined the association between children’s physical activity(PA) and built environment. However, few studies concentrated on demographics as predictors of children’s PA and the results were inconsistent. This study will examine predictors (gender, race/ethnicity, socioeconomic status) of frequency of outdoor and indoor PA among children in the Built Environment and Active Play(BEAP) Study. Approach: In October 2014, questionnaires were mailed to 2000 parents of children aged 7-12 years in Washington DC metropolitan area (DMV). The questionnaire addressed demographics, socioeconomic status, parent’s PA, perceived neighborhood built environment, access to PA facilities and the frequency of children’s outdoor and indoor PA at myriad facilities. Children’s PA will be categorized into never, rarely, sometimes or often. Chi-square test will be used to test for equality of children’s outdoor and indoor PA frequencies by race/ethnicity, gender and household income respectively. Multinomial logistic regression and cumulative logit regression will be performed to examine whether frequency of outdoor and indoor PA is predicted by race/ethnicity, gender, household income controlling for parent’s education (Model A). Additional regression analysis will be performed by further controlling for access to PA facilities, children’s sedentary behaviors and illness diagnosed by doctors, neighborhood built environment and parent’s PA behaviors (Model B). Findings: 144 complete surveys are received for the BEAP Study. The information of 124 children will be used for data analysis after excluding children with disabilities that restricted PA and children residing at other location more than 30% of time in a typical week. No statistically significant differences in frequency of indoor or outdoor PA were observed by race, parent’s education, or household income in preliminary data analysis. This study is currently underway and final results are pending. Conclusions: This study is currently underway and final conclusions are pending. Public Health Significance: It is important to identify determinants, facilitators as well as barriers of children’s PA. Using demographics as predictors could be conducive to identifying the disparity of children’s PA and further facilitating policy making and interventions to reduce the disparity.
