RESUMEN

Purpose: Children in low-income, urban areas are at a greater risk of poor physical activity (PA) and academic outcomes. The purpose of this study was to examine feasibility, acceptability, and engagement of a pilot implementation of the Active Science (AS) exer-learning program in 3rd grade physical education (PE) classes to inform potential upscaling after efficacy evaluation. Methods: AS was implemented within PE at five public schools serving low-income, urban neighborhoods, using a phased implementation approach. A mixed methods approach was utilized; feasibility and engagement were measured using quantitative dose and fidelity measures, students were surveyed regarding acceptability, and PE teachers were interviewed pre/post-intervention regarding perceptions of the program. Results: N = 638 students in k = 25 PE classes across five schools averaged 8.8 weeks of AS implementation with nearly universal inclusivity. Students averaged 1468 steps/session; an average of 15% of available PE class time was spent in MVPA. Semi-structured interviews revealed high staff perceptions of feasibility, as well as specific improvements that should be implemented before upscaling. Conclusions: Process and PA measures indicate high feasibility, with excellent engagement across all five schools. Together with high acceptability reported by students and staff, these results show that AS can feasibly integrate into PE classes low-income, urban schools to improve student engagement in both PA and science learning.

RESUMEN

INTRODUCTION: In the U.S., children regularly consume foods from quick-service restaurants, but little is known about the marketing strategies currently used inside quick-service restaurants. This study aims to validate a child-focused Environmental Assessment Tool for quick-service restaurants, evaluate marketing strategies inside and on the exterior of quick-service restaurants, and examine differences by community race/ethnicity or income. METHODS: The inter-rater and test-retest reliability of the Environmental Assessment Tool were assessed across the top 5 national quick-service restaurant chains. Marketing techniques in 165 quick-service restaurants (33 per national chain) in socioeconomically and racially/ethnically diverse communities throughout New England were examined in 2018-2019. Mixed methods ANOVA examined the differences in marketing techniques in 2020. RESULTS: The inter-rater and test-retest reliability of the Environmental Assessment Tool were high (Cohen's κ>0.80). Approximately 95% of quick-service restaurants marketed less healthy foods, whereas only 6.5% marketed healthy options. When examining the differences by community demographics, there were significantly more price promotion advertisements inside and on the exterior of quick-service restaurants in lower-income communities. In addition, there was a greater number of child-directed advertisements with cartoon or TV/movie characters as well as fewer healthy entrée options and more sugar-sweetened beverage and dessert options on the children's menu inside quick-service restaurants in communities with higher minority populations. CONCLUSIONS: Environmental Assessment Tool is a valid tool to evaluate marketing inside quick-service restaurants. Results suggest that there is a substantial amount of unhealthy food and beverage marketing inside quick-service restaurants, with differences in the number and types of techniques used in lower-income and minority communities. Policies that limit quick-service restaurant marketing to children should be considered.

RESUMEN

Children regularly consume foods from quick service restaurants (QSRs) in the United States, but little is known about how ordering decisions are made and the impact on selection and consumption. A total of n = 218 parents dining with a child (ages 4-16 years) inside a participating QSR completed interviews and demographic surveys and provided their child's leftover foods at the end of the meal. Children's meal consumption was measured using plate-waste methodology. The majority of children selected their meal without parental involvement (80%) and decided what to order prior to entering the QSR (63%). Using mixed-model analysis of variance, children selected and consumed significantly fewer calories and less total fat and sodium when a parent ordered the meal compared with when the child ordered the meal alone. There were no significant differences in selection or consumption when a parent and child ordered the meal together. Approximately one-third of the children consumed foods that were shared. In conclusion, because children primarily select foods without parental involvement and prior to entering QSRs, innovative strategies are needed to influence ordering decisions inside QSRs toward healthier options. Additionally, because food is frequently shared, policies that only focus on children's menus may not be as effective in impacting children's dietary intake.

RESUMEN

OBJECTIVE: To determine the relative effect of interactive digital exercise that features player movement (ie, exergames) on energy expenditure among children of various body mass indexes (BMIs; calculated as weight in kilograms divided by height in meters squared). DESIGN: Comparison study. SETTING: GoKids Boston, a youth fitness research and training center located at University of Massachusetts, Boston. PARTICIPANTS: Thirty-nine boys and girls (mean [SD] age, 11.5 [2.0] years) recruited from local schools and after-school programs. MAIN EXPOSURE: Six forms of exergaming as well as treadmill walking. MAIN OUTCOME MEASURES: In addition to treadmill walking at 3 miles per hour (to convert miles to kilometers, multiply by 1.6), energy expenditure of the following exergames were examined: Dance Dance Revolution, LightSpace (Bug Invasion), Nintendo Wii (Boxing), Cybex Trazer (Goalie Wars), Sportwall, and Xavix (J-Mat). Energy expenditure was measured using the CosMed K4B2 portable metabolic cart. RESULTS: All forms of interactive gaming evaluated in our study increased energy expenditure above rest, with no between-group differences among normal (BMI < 85th percentile) and "at-risk" or overweight (BMI ≥ 85th percentile) children (P ≥ .05). Walking at 3 miles per hour resulted in a mean (SD) metabolic equivalent task value of 4.9 (0.7), whereas the intensity of exergaming resulted in mean (SD) metabolic equivalent task values of 4.2 (1.6) for Wii, 5.4 (1.8) for Dance Dance Revolution, 6.4 (1.6) for LightSpace, 7.0 (1.8) for Xavix, 5.9 (1.5) for Cybex Trazer, and 7.1 (1.7) for Sportwall. Enjoyment of the games was generally high but was highest for children with BMIs in the highest percentiles. CONCLUSION: All games used in our study elevated energy expenditure to moderate or vigorous intensity. Exergaming has the potential to increase physical activity and have a favorable influence on energy balance, and may be a viable alternative to traditional fitness activities for children of various BMI levels.

RESUMEN

Recent American Heart Association/American College of Sports Medicine (AHA/ACSM) guidelines advocate preparticipation screening, planning, and rehearsal for emergencies and automated external defibrillators in all health/fitness facilities. The authors evaluated adherence to these recommendations at 158 recreational service departments in major US universities (51% response rate for 313 institutions queried). Many made their facilities available to unaffiliated residents, with 39% offering programs for those with special medical conditions. Only 18% performed universal preparticipation screening. Twenty-seven percent reported having 1 or more exercise-related instances of cardiac arrest or sudden cardiac death within the past 5 years. Seventy-three percent had an automated external defibrillator, but only 6% reported using it in an emergency. Almost all had written emergency plans, but only 50% posted their plans, and only 27% performed the recommended quarterly emergency drills. The authors' findings suggest low awareness of and adherence to the AHA/ACSM recommendations for identifying individuals at risk for exercise-related cardiovascular complications and for handling such emergencies in university-based fitness facilities.

RESUMEN

BACKGROUND: Development of effective behavioral interventions to promote weight control and physical activity among diverse, underserved populations is a public health priority. Community focused wellness organizations, such as YMCAs, could provide a unique channel with which to reach such populations. This study assessed health behaviors and related characteristics of members of an urban YMCA facility. METHODS: We surveyed 135 randomly selected members of an urban YMCA facility in Massachusetts to examine self-reported (1) physical activity, (2) dietary behaviors, (3) body mass index, and (4) correlates of behavior change among short-term (i.e., one year or less) and long-term (i.e., more than one year) members. Chi-square tests were used to assess bivariate associations between variables, and multivariate linear regression models were fit to examine correlates of health behaviors and weight status. RESULTS: Eighty-nine percent of short-term and 94% of long-term members reported meeting current physical activity recommendations. Only 24% of short-term and 19% of long-term members met fruit and vegetable consumption recommendations, however, and more than half were overweight or obese. Length of membership was not significantly related to weight status, dietary behaviors, or physical activity. Most respondents were interested in changing health behaviors, in the preparation stage of change, and had high levels of self-efficacy to change behaviors. Short-term members had less education (p = 0.02), lower household incomes (p = 0.02), and were less likely to identify as white (p = 0.005) than long-term members. In multivariate models, females had lower BMI than males (p = 0.003) and reported less physical activity (p = 0.008). Physical activity was also inversely associated with age (p = 0.0004) and education (p = 0.02). CONCLUSION: Rates of overweight/obesity and fruit and vegetable consumption suggested that there is a need for a weight control intervention among members of an urban community YMCA. Membership in such a community wellness facility alone might not be sufficient to help members maintain a healthy weight. The data indicate that YMCA members are interested in making changes in their dietary and physical activity behaviors. Targeting newer YMCA members might be an effective way of reaching underserved populations. These data will help inform the development of a weight control intervention tailored to this setting.

RESUMEN

Obesity has reached epidemic proportions in the United States. More than 60 percent of U.S. adults are now overweight or obese (defined as at least 30 lb [13.6 kg] overweight), predisposing more than 97 million Americans to a host of chronic diseases and conditions. Physical activity has a positive effect on weight loss, total body fat, and body fat distribution, as well as maintenance of favorable body weight and change in body composition. Many of the protective aspects of exercise and activity appear to occur in overweight persons who gain fitness but remain overweight. Despite the well-known health and quality-of-life benefits of regular physical activity, few Americans are routinely active. Results of research studies have shown that physician intervention to discuss physical activity (including the wide array of health benefits and the potential barriers to being active) need not take more than three to five minutes during an office visit but can play a critical role in patient implementation. This article describes elements of effective counseling for physical activity and presents guidelines for developing physical activity programs for overweight and obese patients.

RESUMEN

Obesity has reached epidemic proportions in the United States and in most industrialized nations. More than 60% of US adults are now overweight or obese, predisposing over 97 million Americans to a host of chronic lifestyle diseases, particularly cardiovascular disease. Despite the existence of explicit evidence-based consensus reports on the health risks of obesity and the health benefits of even moderate amounts of weight loss, many patients do not receive advice from their health care providers to lose weight or on how to do so effectively. Even modest physical activity and small incremental healthy dietary changes when incorporated into one's lifestyle have a positive effect on weight loss and promote the maintenance of favorable body weight and body composition changes with advancing age. This article describes elements of effective counseling and practical guidelines for developing a healthy lifestyle approach for overweight and obese individuals.

RESUMEN

The purpose of this investigation was to determine whether the Rockport one-mile walk test equation to predict maximal oxygen uptake was valid for application to treadmill walking. When the Rockport model was found to be inappropriate, a new regression model was developed for predicting peak oxygen uptake (VO2peak) from a one-mile treadmill walk. 304 healthy volunteers ages 40 to 79 years (mean age = 57.6 years, 154 men and 150 women) completed a VO2peak test and a one-mile treadmill walk. Stepwise regression was used to build a model for the relationship between VO2peak and a variety of predictor variables in a sub-sample development group (n = 154). This new model was then applied to a sub-sample validation group (n = 150). The new equation produced a correlation of 0.87, SEE = 4.7 ml x kg (-1) x min (-1) with a mean residual of 0.96 ml x kg (-1) x min (-1). The equation for predicting VO2peak developed in this investigation provides a means of assessing VO2peak that is easy to administer, allows for careful supervision of subjects, and can be completed at a low financial and temporal cost.
