School-based physical education programs: evidence-based physical activity interventions for youth in Latin America

This article focuses on results of the systematic review from the Guide for Useful Interventions for Activity in Latin America project related to school-based physical education (PE) programs in Latin America. The aims of the article are to describe five school-based PE programs from Latin America, discuss implications for effective school-based PE recommendations, propose approaches for implementing these interventions, and identify gaps in the research literature related to physical activity promotion in Latin American youth. Following the US Community Guide systematic review process, five school-based PE intervention studies with sufficient quality of design, execution and detail of intervention and outcomes were selected for full abstraction. One study was conducted in Brazil, two studies were conducted in Chile and two studies were conducted on the US/Mexico border. While studies presented assorted outcomes, methods and duration of interventions, there were consistent positive increases in physical activity levels for all outcomes measured during PE classes, endurance and active transportation to school in all three randomized studies. Except for one cohort from one study, the non-randomized studies showed positive intervention effects for moderate and vigorous physical activity levels during PE classes. The core elements of these five interventions included capacity building and staff training (PE specialists and/or classroom teachers); changes in the PE curricula; provision of equipment and materials; and adjustment of the interventions to specific target populations. In order to translate the strong evidence for school-based PE into practice, systematic attention to policy and implementation issues is required.

The Ciclovia and Cicloruta Programs: Promising Interventions to Promote Physical Activity and Social Capital in Bogotá, Colombia

OBJECTIVES We compared participants from the Ciclovia (streets temporarily closed to motorized vehicles and open for pedestrians) and Cicloruta (bicycle paths) programs in Bogotá, Colombia, to assess associations of program participation with physical activity, safety, social capital, and equity. METHODS We conducted 2 cross-sectional studies in October 2009 with intercept surveys: one among 1000 Ciclovia participants and the other among 1000 Cicloruta participants. RESULTS Most Ciclovia participants met the physical activity recommendation in leisure time (59.5%), and most Cicloruta participants met it by cycling for transportation (70.5%). Ciclovia participants reported a higher perception of safety (51.2% regarding traffic and 42.4% about crime) and social capital (odds ratio = 2.0; 95% confidence interval = 1.4, 2.8) than did Cicloruta users. Most Cicloruta users reported living in low socioeconomic status categories (53.1%), had lower educational attainment (27%), and did not own cars (82.9%). Most Ciclovia participants reported living in middle socioeconomic status categories (64%), had low-to-middle educational attainment (51.1%), and did not own cars (66.1%). CONCLUSIONS The Ciclovia and Cicloruta programs have the potential to equitably promote physical activity and provide a mobility alternative in complex urban settings such as Bogotá.

Atlanta Streets Alive: A Movement Building a Culture of Health in an Urban Environment

BACKGROUND Open Streets are community-based programs that promote the use of public space for physical activity (PA), recreation and socialization by closing streets temporarily to motorized vehicles, allowing access to pedestrians. The city of Atlanta hosted its first Open Streets event, Atlanta Streets Alive (ASA), in May 2010. An evaluation of the first 5 ASA events from May 2010 to May 2012 was conducted. The purpose was to learn about the characteristics of ASA participants, the influence of the event on their PA, and perceptions of safety and neighborhood social capital. METHODS ASAs evaluation had 2 components: participant counts and a participant survey. Characteristics of participation were compared among the 3 different events in which surveys were conducted using the Pearson χ2 test and F test as appropriate. RESULTS The estimated participation at ASA increased from nearly 3,500 (ASA 1 to 4) to 12,520 (ASA 5). The number of events increased to 3 per year for a total of 10 events until 2014. Overall, 19.4% of participants met the weekly PA recommendation during 1 event. CONCLUSIONS The expanding diversity of routes, participants, and sponsorships highlights the potential promise such programming offers in terms of establishing an urban culture of health.

Umbrella and Systematic Review Methodology to Support the 2018 Physical Activity Guidelines Advisory Committee

INTRODUCTION In 2016, the 2018 Physical Activity Guidelines Advisory Committee, a group of experts in exercise science and health, began an extensive review of the literature to inform the second edition of the Physical Activity Guidelines for Americans. METHODS The purpose of this paper is to describe the evidence-based methodology used to review, evaluate, and synthesize published, peer-reviewed physical activity research. The protocol-driven methodology was designed to maximize transparency, minimize bias, and ensure relevant, timely, and high-quality systematic reviews. Training protocols, quality control procedures, search strategies, assessment instruments, abstraction guides and forms, and reporting templates were developed. RESULTS A systematic approach was used to select the evidence for the 2018 Physical Activity Guidelines Advisory Committee Scientific Report that included umbrella reviews and systematic reviews. Within 16 months, 38 searches were conducted; and 20,838 titles, 4913 abstracts, and 2139 full texts were triaged. Of those, 1130 articles were abstracted to answer 38 research questions. CONCLUSIONS To inform population-based physical activity guidelines, this systematic process facilitated a vast review of the literature on physical activity and health in a short period of time. This flexible, yet rigorous and transparent process included a clear and detailed methodology with a focus on training and quality control.
