Decreases in physical activity and increases in screen time activities have been blamed for the upward trend in childhood overweight. The purpose of this study was to determine the prevalence of overweight as well as to determine which students met recommendations for physical activity and screen time activities. A total of 215 students enrolled in Kaleida Health School Based Health Centers (SBHCs) of three Buffalo Public Schools participated in this study. Using the SEARCH for Diabetes in Youth Questionnaire, data was obtained about frequency and duration of vigorous physical activity (VPA), non-vigorous physical activity (NVPA), strength activities, and screen time activities including television viewing, video game playing, and computer use. 89.3% of this cohort was African American, and 65.6% were female. 44.7% of children were overweight, 25% met recommendations for VPA, 22.3%% met recommendations for NVPA, and only 12.1% met recommendations for strength activities. 90.2% of children reported exceeding screen time activities. Logistic regressions determined that excessive screen time was most predictive of overweight, and presence of pre-hypertension was most predictive of inadequate VPA. This data indicates that lifestyle factors such as increasing physical activity and decreasing sedentary screen time activities need to be promoted in order to prevent further increases in childhood overweight.
