“…Intervention effects for the primary and secondary outcomes were examined by using linear mixed models adjusted for school clustering and participant socioeconomic status, and all analyses followed the intention-to-treat principle. 36 Prespecified subgroup analyses 21 for all body composition outcomes were conducted for those classified as overweight/obese (combined as a single group) at baseline. In addition, the proportional difference between treatment groups among those improving their weight status (ie, moving from "obese" to "overweight" or from "overweight" to "healthy weight") or regressing to a poorer weight status (ie, moving from "healthy weight" to "overweight" or from "overweight" to "obese") was explored by using Pearson' s x 2 test.…”

“…20 The rationale and study protocols have been reported previously. 21 Briefly, ATLAS was evaluated by using a cluster randomized controlled trial conducted in state-funded coeducational secondary schools within low-income areas of New South Wales, Australia. The SocioEconomic Indexes For Areas (SEIFA) of relative socioeconomic disadvantage (scale: 1 = lowest to 10 = highest) was used to identify eligible schools.…”

“…21 In summary, ATLAS is a multicomponent intervention designed to prevent unhealthy weight gain by increasing physical activity, reducing screen-time, and lowering SSB consumption among adolescent boys attending schools in low-income areas. Self-determination theory 25 and social cognitive theory 26 formed the theoretical basis of the program.…”

OBJECTIVE: The goal of this study was to evaluate the impact of the Active Teen Leaders Avoiding Screen-time (ATLAS) intervention for adolescent boys, an obesity prevention intervention using smartphone technology. METHODS: ATLAS was a cluster randomized controlled trial conducted in 14 secondary schools in low-income communities in New South Wales, Australia. Participants were 361 adolescent boys (aged 12–14 years) considered at risk of obesity. The 20-week intervention was guided by self-determination theory and social cognitive theory and involved: teacher professional development, provision of fitness equipment to schools, face-to-face physical activity sessions, lunchtime student mentoring sessions, researcher-led seminars, a smartphone application and Web site, and parental strategies for reducing screen-time. Outcome measures included BMI and waist circumference, percent body fat, physical activity (accelerometers), screen-time, sugar-sweetened beverage intake, muscular fitness, and resistance training skill competency. RESULTS: Overall, there were no significant intervention effects for BMI, waist circumference, percent body fat, or physical activity. Significant intervention effects were found for screen-time (mean ± SE: –30 ± 10.08 min/d; P = .03), sugar-sweetened beverage consumption (mean: –0.6 ± 0.26 glass/d; P = .01), muscular fitness (mean: 0.9 ± 0.49 repetition; P = .04), and resistance training skills (mean: 5.7 ± 0.67 units; P < .001). CONCLUSIONS: This school-based intervention targeting low-income adolescent boys did not result in significant effects on body composition, perhaps due to an insufficient activity dose. However, the intervention was successful in improving muscular fitness, movement skills, and key weight-related behaviors.

Smartphone applications are increasingly being used to support nutrition improvement in community settings. However, there is a scarcity of practical literature to support researchers and practitioners in choosing or developing health applications. This work maps the features, key content, theoretical approaches, and methods of consumer testing of applications intended for nutrition improvement in community settings. A systematic, scoping review methodology was used to map published, peer-reviewed literature reporting on applications with a specific nutrition-improvement focus intended for use in the community setting. After screening, articles were grouped into 4 categories: dietary selfmonitoring trials, nutrition improvement trials, application description articles, and qualitative application development studies. For mapping, studies were also grouped into categories based on the target population and aim of the application or program. Of the 4818 titles identified from the database search, 64 articles were included. The broad categories of features found to be included in applications generally corresponded to different behavior change support strategies common to many classic behavioral change models. Key content of applications generally focused on food composition, with tailored feedback most commonly used to deliver educational content. Consumer testing before application deployment was reported in just over half of the studies. Collaboration between practitioners and application developers promotes an appropriate balance of evidence-based content and functionality. This work provides a unique resource for program development teams and practitioners seeking to use an application for nutrition improvement in community settings. Adv Nutr 2017;8:308-22.

“…Theoretically, based-interventions are more effective in changing behavior than non-theoretical approaches [1][2][3][4] . Bandura's SCT 5 is a useful framework for explaining why people acquire and maintain health behaviors, as well as to hypothesize that a behavior change is influenced by a complex interaction referred to as "reciprocal determinism", which occurs between personal factors, environmental factors, and factors influenced by the other's behavior 5,6 .…”

Establishing valid and reliable methods for assessing social cognitive measures of dietary behaviors support the design and delivery of more effective interventions. The aims of this study were to culturally adapt social cognitive measures related to adolescent dietary behaviors and evaluate the reliability and factorial validity of these measures in Brazilian adolescents. The instrument was culturally adapted from an Australian questionnaire based on the Banduras' Social Cognitive Theory, and it included the following constructs: self-efficacy, intentions, situation, social support, behavioral strategies, and outcome expectations and expectancies. The questionnaire was administered in a two-week test-retest with 173 adolescents (M=15.3±1.53 years old). A confirmatory factor analysis was employed to examine model-fit for each scale using multiple indices including: chi-square, comparative-fit, goodness-of-fit, and root mean square error of approximation. Reliability properties were also examined. The reliability and factorial validity are appropriate, suggesting for each scale values between adequate to exact; internal consistency from acceptable to excellent (α=0.66 to 0.94); and rank order repeatability from adequate to strong (ICC=0.65-0.93). The Brazilian version showed appropriate internal consistency, factorial validity and test-retest reliability, and will be useful to assess social cognitive dietary behaviors among Brazilian adolescents.Keywords: adolescents; feeding behavior; measures; validation studies. ResumoO estabelecimento de métodos validados e confiáveis para avaliar os aspectos sociais cognitivos do comportamento dieté-tico suportam o delineamento e o desenvolvimento de intervenções mais efetivas. Os objetivos deste estudo foram adaptar um instrumento que avalia os aspectos sociais cognitivos do comportamento dietético, bem como a sua confiabilidade e validade fatorial confirmatória em adolescentes brasileiros. O instrumento foi culturalmente adaptado de um questionário australiano baseado na Teoria Cognitiva Social de Bandura, que incluiu os seguintes construtos: autoeficácia, intenções, situação, apoio social, estratégias comportamentais, expectativas e preditores de expectativas. O questionário foi administrado com duas semanas de teste-reteste em 173 adolescentes (M=15,3±1,53 anos). A análise confirmatória fatorial foi empregada para examinar o modelo de ajuste para cada escala utilizando múltiplos índices que incluíam: qui-quadrado, comparative-fit (CFI), goodness-of-fit (GFI) e o root mean square error of aproximation (RMSEA) As propriedades de confiabilidade também foram avaliadas. A validade fatorial e confiabilidade estão adequadas, sugerindo para cada escala valores entre adequado a exato; consistência interna de aceitável à excelente (α=0,66 a 0,94) e repetitividade da ordem de classificação de adequada à forte (ICC=0,65 a 0,93). A versão brasileira apresentou consistência interna, validade fatorial e confiabilidade do teste-reteste aceitá-veis, e poderá ser útil para avaliar...
