The purpose of the present investigation was to examine schoolchildren's volume and type of PA during school-time and out-of-school, compared to national recommendations and differences by sex and weight status. Methods: This cross-sectional analysis included 517 3 rd-5 th grade schoolchildren from 13 New England elementary schools (October 2013-January 2014). Demographics were collected by parent questionnaire. Measured height and weight were used to categorize child weight status. Accelerometer data were collected over 7 days. PA was coded as total activity counts and minutes of sedentary, light, and moderate-to-vigorous physical activity (SED, LPA, MVPA) during 1) school, 2) weekday out-of-school, 3) weekend, and 4) total daily time. Multivariable mixed models were used to examine associations between sex and weight status and total counts, SED, LPA, and MVPA, controlling for demographics, wear-time, and clustering within schools. Results: 453 participants (60.5 % girls; mean age 9.1 years; 30.5 % overweight/obese) had valid accelerometer wear time (≥3 days, ≥ 10 h/day). Few children achieved 60 min total daily (15.0 %) or school-time (8.0 %) MVPA recommendations. For all time-of-day categories, girls achieved fewer MVPA minutes than boys (p < .0001), and overweight/obese participants achieved fewer MVPA minutes than normal/underweight participants (p = 0.05). Minutes of LPA declined by grade-level (p < .05) and were lower in girls than boys during school-time only (p < .05). Conclusion: Disparities in MVPA by sex and weight status across school and out-of-school time highlight the need for programs with equitable reach.

Expanding upon this evidence requires validated measures to assess nutrition and physical activity (PA) environments across large samples of OST programs. The aim of this study was to assess the criterion validity of the Out-of-School-Time Snacks, Beverages, and Physical Activity Questionnaire (OST-SBPA), an online questionnaire designed to measure OST nutrition and PA environments by program leaders' reports. The study consisted of two samples of OST programs (total n=65). Objective data across program meetings were compared to program leaders' reports of usual snack, beverage, and PA offerings. All 65 programs provided snack and beverage data; PA data were available from 31 programs. Validity was assessed using percent agreement, Cohen's kappa, and Spearman's correlations. All OST-SBPA items demonstrated agreement above 60% when dichotomi...

Sociodemographics, years of residence in the U.S., behavioral data, and responses to the Caregiver's Feeding Styles Questionnaire (CFSQ) were obtained from the mother. Measured heights and weights were obtained for both mother and child. Child dietary intake was assessed using the Block Food Screener. Separate multiple linear regression models were run, adjusting for child and

Live Well, a community-based participatory research (CBPR) study, was designed to address this gap. Objective-The goal of this paper is to describe the development of the Live Well nutrition and physical activity curriculum. Methods-The curriculum draws on behavioral theory and popular education and was cocreated, implemented, and will be evaluated by community partners and academic researchers. Results-The time it took to develop the curriculum exceeded initial estimates. However, the extra time taken was spent engaging in needed dialogue to create a better product, fully co-created by academic and community partners. Additionally, working with an outside expert created the opportunity for all partners to train together, build capacity, and increase cohesion. Our approach developed relationships and trust, and resulted in a unique curriculum. Conclusions-The commitment to partnership resulted in a curriculum to empower immigrant women to improve health decisions and behaviors. This will inform future research and programming targeting other at-risk and new immigrant communities.

Over the last several decades, the prevalence of obesity among both adults and children has grown at an alarming rate and is now reaching epidemic proportions. The increase in obesity has been associated with rises in a host of other chronic conditions including cardiovascular disease, type 2 diabetes, and some cancers. While the causes of obesity are multifaceted, there is growing evidence that television viewing is a major contributor. Results of numerous studies indicate a direct association between time spent watching television and body weight. Possible explanations for this relationship include: 1) watching television acts as a sedentary replacement for physical activity; 2) food advertisements for nutrient-poor, high-calorie foods stimulate food intake; and 3) television viewing is associated with "mindless" eating. In addition to decreasing physical activity and increasing the consumption of highly palatable foods, television viewing can also promote weight gain in indirect ways, such as through the use of targeted product placements in television shows; by influencing social perceptions of body image; and airing programs that portray cooking, eating and losing weight as entertainment. This paper will provide an interdisciplinary review of the direct and indirect ways in which television influences the obesity epidemic, and conclude with ways in which the negative impact of television on obesity could be reduced.

Methods-Baseline data from 383 mothers were used for this study. Dyads attended a measurement day, where they completed self-administered surveys collecting information about socio-demographics, diet, physical activity, other psychosocial variables, and height and weight. Results-Haitian mothers' socio-demographic profile differed significantly from that of Brazilians' and Latinas': They have been in the US for a shorter period of time, have higher rates of unemployment, are less likely to be married, more likely to have ≥3 children, more likely to be obese, and have immigrated for family or other reasons. In multivariate models, self-reported changes in diet and physical activity since migrating to the US were significantly associated with BMI with non-linear relationships identified.
