The Central Texas Coordinated Approach To Child Health (CATCH) Middle School Project is a 3.5-year school-based project aimed at promoting physical activity (PA), healthy eating, and obesity prevention among public middle school students in Texas. This article describes the CATCH intervention model and presents baseline findings from spring 2009. CATCH comprises six core components: CATCH Team, CATCH PE, CATCH Classroom, CATCH Eat Smart Cafeteria, CATCH Family, and CATCH Social Marketing. A group randomized serial cross-sectional design is being employed to test the effect of three program support conditions (n = 10 schools each) on energy-balance behaviors: Basic (training and curriculum only), Basic Plus (training and curriculum plus CATCH facilitator support), and Basic Plus Social Marketing (all inputs plus social marketing component). The study sample is composed of a cross-sectional sample of eighth-grade students (primary outcome evaluation sample) and sixth- and seventh-grade students (PE process evaluation sample) who are selected and measured each year. At baseline, 37.9% of eight-grade students (n = 2,841; 13.9 years) were overweight/obese and 19.2% were obese. Eighth-grade students reported, on average, consuming sugar-sweetened beverages more than two times on the previous day and fruits and vegetables roughly three times on the previous day; only two of five school districts surpassed the recommended 50% cut-point for class time spent in moderate-and-vigorous PA as measured in classes of sixth- and seventh-grade students. Additional behavioral findings are reported. Body mass index and behaviors were comparable across conditions. Baseline findings underscore the need to promote student energy-balance behaviors.

Objective. The purpose of this study was to examine the psychometric properties of the self-efficacy for healthy eating and physical activity measure (SE-HEPA) for preadolescents. Method. The reliability of the measure was examined to determine if the internal consistency of the measure was adequate (i.e., ?s > .70). Next, in an effort to determine if a two-factor model was a better fit than a one-factor model, as hypothesized, an exploratory factor analysis in a confirmatory factor analysis framework was used to determine model fit. Additionally, the criterion-related validity of the measure was evaluated by conducting correlational analyses to determine if SE-HEPA scores were associated with preadolescent body mass index. Results. Consistent with the hypotheses, Cronbach’s alphas indicated good reliability for the measure (i.e., ?s > .70) and factor analyses indicated the two-factor model provided a better fit than the one-factor model. Additionally, correlations revealed a significant relationship between the two factors (i.e., healthy eating, physical activity) and preadolescent body mass index. Conclusions. The SE-HEPA will allow researchers and clinicians to better understand self-efficacy for behaviors important to weight loss among preadolescents. This could, in turn, inform future efforts aimed at increasing behaviors that promote healthy weight status among this population within the context of family-based weight loss programs.

This study examined the relation between the chain food retail environment surrounding schools, youths’ lunchtime eating behavior, and youths’ obesity levels across three countries. Participants consisted of 26,778 students 13-15 years old from 687 schools across Canada, Scotland and the US. The density of convenience stores, chain fast food restaurants, and chain cafés within 1km of each school was measured. Lunchtime eating behaviors, weight, and height were self-reported. Although the density of chain food retailers was highest in the US, fewer American students (2.6%) routinely ate their lunch at a food retailer during the school week than did Canadian (7.7%) and Scottish (43.7%) students. The density of chain food retailers was associated with eating lunch at a food retailer in Canada only whereby students attending schools with 1-2, 3-4, and 5+ chain food retailers within 1km from their schools were 1.39 (95% CI: 0.84-2.29), 1.87 (95% CI: 1.10-3.20), and 2.50 (95% CI: 1.56-4.01) times more likely to eat at a chain food retailer compared to students attending schools with no nearby chain food retailers. No associations were found between chain food retailer density and obesity.
