RESUMEN
The international physical inactivity epidemic among children has contributed to child obesity. Schools can be an effective source of physical activity opportunity. A cross-sectional sample of 1306 American children was drawn from the Panel Study of Income Dynamics - Child Development Supplement, 2007. The aim of this study was to determine the role of in-school physical activity on body mass index (BMI) percentile among middle and high school-aged children. Multinomial logistic regression was used to assess the associations between the independent variable, physical activity, and the dependent variable, BMI percentile. After adjusting for covariates, children who had no physical activity during physical education (PE) were much more likely to be obese than normal weight in comparison with those who met the US national requirements (odds ratio = 1.58, confidence interval = 1.14, 2.20). This study suggests that meeting US national guidelines for PE-related physical activity may be effective in preventing obesity.

The objective of this study was to determine (a) activity preferences for low-income sedentary urban African American older adults and (b) information needed to deliver a lay physical activity intervention in the community for this population. This descriptive qualitative study used six focus groups. Participants were African American, 55 and older, had low incomes, and had sedentary behavior. Physical activity themes included excitement/emotion for physical activity, group physical activity, and location of physical activity. Themes regarding aspects of being a lay community health worker included beneficial service, uncertainty, logistics concerns, and delivery method preferences. The findings from this study will provide the basis for an intervention for low-income sedentary African American older adults. Preferences for physical activity, concerns about and supports needed for individuals to serve as lay community health workers, various types of training materials, and preferred technology for physical activity participation are identified and discussed.

BACKGROUND: This study assessed the association between amount of physical activity and body mass index (BMI) percentile among middle and high school children. Total daily physical activity needs to include both in and out of school physical activity. METHODS: A secondary data analysis was performed on 1306 children drawn from the Panel Study of Income Dynamics Child Development Supplement (CDS III, 2007). The dependent variable in this study was BMI percentile, while the independent variable was physical activity. The multinomial logistic regression model was used to assess the associations between physical activity and BMI percentile controlling for age, gender, race/ethnicity, parental income, and neighborhood safety. RESULTS: Children who engaged in low daily physical activity levels had 1.8 times the odds of being obese versus normal weight than those who engaged in moderate levels [odds ratio (OR) = 1.80, confidence interval (CI) = 1.31, 2.48]. African-American children had 1.6 times the odds of being obese than normal weight (OR = 1.55, CI = 0.99, 2.43) and Hispanic children had approximately 1.8 times the odds of being obese than normal weight in comparison to non-Hispanic white children (OR = 1.79, CI = 1.00, 3.21). Females had about 1.5 times the odds of being overweight than normal weight than males (OR = 1.49, CI = 1.04, 2.13). CONCLUSIONS: This study suggests that the accumulation of 30 minutes or more of daily physical activity may be effective in decreasing obesity prevalence among middle and high school-aged children.
