Abstract
INTRODUCTION In the United States, non-Hispanic Black adolescents have a significantly higher prevalence of obesity than their peers. Though physical activity (PA) has many benefits, many adolescents fail to engage in adequate amounts of PA. Black adolescents are also more sedentary than those from other races and ethnicities. This study aimed to describe the perceptions, beliefs, and barriers to PA in South Florida Black adolescents. METHODS Five focus groups were conducted with self-identified non-Hispanic Black adolescents (n = 38) in South Florida. A semi-structured question guide based on the Theory of Planned Behavior was used for group discussions. The open-ended questions addressed adolescents' (1) attitudes and beliefs toward PA, (2) current PA-related behaviors, and (3) environmental, social, cultural, and racial influences on health behaviors. RESULTS The desire to be healthy, thoughts of the future, and self-image were among the reasons participants engaged in PA. Engagement in PA was associated with a positive social environment, including encouragement from family and friends. Race, culture, and social media were also cited as influences on PA. Perceived control beliefs, such as parental pressures and self-discipline, also impacted PA. CONCLUSION Adolescents recognize the importance of PA; however, their behaviors do not reflect this. Barriers and motivators for Black adolescents are multifaceted. It is critical for Public Health practitioners and local legislators to understand the complexities to serve this population. This study's findings can guide the development of tailored PA and education programs for Black adolescent populations.

Abstract
Context: Educational interventions on type 2 diabetes can have life-saving effects. A closer analysis of studies in this area contributes to well-designed interventions. Objectives: We surveyed the effectiveness of interventional studies on type 2 diabetes in the last decade. Data Sources: The research papers were obtained from PubMed, Science Direct, Scopus, Web of Science, Google Scholar, SID, and Magiran for Persian and English language studies between 2010 and 2019. The PRISMA checklist was used to select the studies for systematic reviews. Study Selection: The criteria for article selection were experimental studies, quasi-experimental studies, clinical trials, and pre-treatment and post-treatment observations. Also, the exclusion criteria were case studies, short articles, cross-sectional studies, descriptive and analytic studies, letters to the editor, and systematic review papers. Finally, 24 studies (out of 1,374) were entered in our study. Data Extraction: An interventional study checklist was used to report the standard of studies: (1) consolidated standards of reporting trials with 25 items; (2) checklist for experimental design with nine items; (3) checklist for quasi-experimental studies with nine items; and (4) transparent reporting of evaluations with non-randomized designs with 22 items. Results: Twenty-four research papers entered the final analysis. Most studies were clinical trials with the intervention period ranging from one to 12 months. Patients were usually selected as the participants. The education interventions in most studies were lectures, questions/answers, group discussions, brainstorming, photo/film/slide display, group teaching, individual training, individual counseling, and group counseling. The main focus of the interventions was on physical activity and diet, with positive effects. Conclusions: Most interventions made on type 2 diabetes variables had positive effects. Therefore, it is recommended that in addition to diet and physical activity, other factors of type 2 diabetes be considered in educational interventions. Also, the most effective and appropriate teaching methods should be considered to prevent and control this disease.

Abstract
PURPOSE OF REVIEW Adolescence represents a critical time to set habits for long-term health, yet adequate rates of physical activity are uncommon in this age group. Mobile technology use, however, is ubiquitous. We review advantages and challenges posed by mobile health (mHealth) and telehealth-based physical activity interventions aimed at adolescents. RECENT FINDINGS Mobile Health (mHealth) and telehealth interventions to increase physical activity in adolescents include use of wearable activity trackers, text messages or apps, and video visits with exercise specialists. Definitions and goals for physical activity differ across interventions, and methods of activity measurement also vary. User engagement is often poor, if tracked at all. No identified studies included use of behavioral economics-informed engagement strategies. Intervention designers must plan for ways to maximize engagement and to reliably measure the intended outcome. Although mHealth and telehealth interventions have advantages such as scalability and acceptability, potential pitfalls must be addressed before widespread implementation.

Abstract
CONTEXT The use of the internet and technology as a medium for delivering online nutrition education (ONE) has increased; however, evidence-based studies exploring factors that contribute to best practices in online interventions have not emerged. OBJECTIVE The purpose of this systematic review was to identify factors that contributed to successful ONE interventions in relation to research studies published between 2009 and 2018. DATA SOURCES Following the PRISMA guidelines, relevant studies were identified through PubMed, Medline, Web of Science, Science Direct, and Education Resources Information Center (ERIC) databases. DATA EXTRACTION Five authors screened and determined the quality of the studies using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system and extracted the data from the articles. DATA ANALYSIS Twenty-seven studies were included: 21 studies were website-based, 3 were delivered through smartphone application, 2 were delivered as online courses, and 1 used text messages. Tailored messages/feedback, interaction between participants and investigators, identification of specific behaviors, use theory, adequate duration, and alignment between stated objectives and activities were factors that contributed to successful online interventions, while comparison bias and the lack of specific details on duration and dosage, tracking system, objective outcome measurements, and follow-up were factors that may have interfered with successful ONE interventions. CONCLUSIONS The findings underscore the importance of developing ONE intervention designs that utilize factors unique to online platforms for effective interventions aimed at behavior change.

Abstract
AIMS To evaluate theory-based psychological approaches that have been effective in promoting behavior change in interventions promoting a Mediterranean style diet (MD) for the reduction of cardiovascular disease (CVD) risk. DATA SYNTHESIS A systematic review of primary research articles using PRISMA recommendations was conducted. References were retrieved using keyword searches from MEDLINE via PUBMED and included studies targeted participants at high risk for CVD. Two hundred and ninety one studies were reviewed; however, only six met the inclusionary criteria. Three articles describe the same intervention; therefore, only four were included. Included studies incorporated social cognitive theory, social learning theory, goal-system theory, social ecological theory, selfdetermination theory, and the transtheoretical model of behavior change. Overall, studies were nutrition interventions in clinical settings with participants at high risk for or with CVD. CONCLUSIONS Results from use of the social cognitive theory and self-determination theory in increasing MD adherence for the reduction of CVD risk and events are encouraging. However, we encourage future long-term interventions focusing on dietary behavior change to provide not only an in-depth description of the psychological methodologies used but also how these methodologies were implemented in order ascertain the most effective theory for promoting dietary behavior change towards patterns of a MD.

Abstract
To strengthen randomized controlled trials (RCT) evaluating the efficacy of 100% watermelon juice on vascular function of older women, theory-driven behavioral analysis as well as comparative sensory analysis of the intervention and placebo were conducted. The Theory of Planned Behavior was adopted to assess psychosocial determinants of intention to consume watermelon juice. Sensory attributes were assessed utilizing hedonic scales. Analysis included Structural Equation Modeling with maximum likelihood. The measurement model provided a good fit (x2 = 70.22, df = 38; RMSEA = 0.07, CFI = 0.98; NFI = 0.95). Attitude (γ = 0.36), subjective norm (γ = 0.43), and perceived behavioral control (γ = 0.21,) were significant predictors (p < 0.001) of intention. Participants identified no significant differences in sensorial attributes between beverages, thereby minimizing sensory bias and discrimination. Similar approaches may help other RCT investigating novel foods and bioactive compounds bridge gaps between efficacy and effectiveness.

Abstract
BACKGROUND The global prevalence of childhood and adolescent obesity is high. Lifestyle changes towards a healthy diet, increased physical activity and reduced sedentary activities are recommended to prevent and treat obesity. Evidence suggests that changing these health behaviours can benefit cognitive function and school achievement in children and adolescents in general. There are various theoretical mechanisms that suggest that children and adolescents with excessive body fat may benefit particularly from these interventions. OBJECTIVES To assess whether lifestyle interventions (in the areas of diet, physical activity, sedentary behaviour and behavioural therapy) improve school achievement, cognitive function (e.g. executive functions) and/or future success in children and adolescents with obesity or overweight, compared with standard care, waiting-list control, no treatment, or an attention placebo control group. SEARCH METHODS In February 2017, we searched CENTRAL, MEDLINE and 15 other databases. We also searched two trials registries, reference lists, and handsearched one journal from inception. We also contacted researchers in the field to obtain unpublished data. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials (RCTs) of behavioural interventions for weight management in children and adolescents with obesity or overweight. We excluded studies in children and adolescents with medical conditions known to affect weight status, school achievement and cognitive function. We also excluded self- and parent-reported outcomes. DATA COLLECTION AND ANALYSIS Four review authors independently selected studies for inclusion. Two review authors extracted data, assessed quality and risks of bias, and evaluated the quality of the evidence using the GRADE approach. We contacted study authors to obtain additional information. We used standard methodological procedures expected by Cochrane. Where the same outcome was assessed across different intervention types, we reported standardised effect sizes for findings from single-study and multiple-study analyses to allow comparison of intervention effects across intervention types. To ease interpretation of the effect size, we also reported the mean difference of effect sizes for single-study outcomes. MAIN RESULTS We included 18 studies (59 records) of 2384 children and adolescents with obesity or overweight. Eight studies delivered physical activity interventions, seven studies combined physical activity programmes with healthy lifestyle education, and three studies delivered dietary interventions. We included five RCTs and 13 cluster-RCTs. The studies took place in 10 different countries. Two were carried out in children attending preschool, 11 were conducted in primary/elementary school-aged children, four studies were aimed at adolescents attending secondary/high school and one study included primary/elementary and secondary/high school-aged children. The number of studies included for each outcome was low, with up to only three studies per outcome. The quality of evidence ranged from high to very low and 17 studies had a high risk of bias for at least one item. None of the studies reported data on additional educational support needs and adverse events.Compared to standard practice, analyses of physical activity-only interventions suggested high-quality evidence for improved mean cognitive executive function scores. The mean difference (MD) was 5.00 scale points higher in an after-school exercise group compared to standard practice (95% confidence interval (CI) 0.68 to 9.32; scale mean 100, standard deviation 15; 116 children, 1 study). There was no statistically significant beneficial effect in favour of the intervention for mathematics, reading, or inhibition control. The standardised mean difference (SMD) for mathematics was 0.49 (95% CI -0.04 to 1.01; 2 studies, 255 children, moderate-quality evidence) and for reading was 0.10 (95% CI -0.30 to 0.49; 2 studies, 308 children, moderate-quality evidence). The MD for inhibition control was -1.55 scale points (95% CI -5.85 to 2.75; scale range 0 to 100; SMD -0.15, 95% CI -0.58 to 0.28; 1 study, 84 children, very low-quality evidence). No data were available for average achievement across subjects taught at school.There was no evidence of a beneficial effect of physical activity interventions combined with healthy lifestyle education on average achievement across subjects taught at school, mathematics achievement, reading achievement or inhibition control. The MD for average achievement across subjects taught at school was 6.37 points lower in the intervention group compared to standard practice (95% CI -36.83 to 24.09; scale mean 500, scale SD 70; SMD -0.18, 95% CI -0.93 to 0.58; 1 study, 31 children, low-quality evidence). The effect estimate for mathematics achievement was SMD 0.02 (95% CI -0.19 to 0.22; 3 studies, 384 children, very low-quality evidence), for reading achievement SMD 0.00 (95% CI -0.24 to 0.24; 2 studies, 284 children, low-quality evidence), and for inhibition control SMD -0.67 (95% CI -1.50 to 0.16; 2 studies, 110 children, very low-quality evidence). No data were available for the effect of combined physical activity and healthy lifestyle education on cognitive executive functions.There was a moderate difference in the average achievement across subjects taught at school favouring interventions targeting the improvement of the school food environment compared to standard practice in adolescents with obesity (SMD 0.46, 95% CI 0.25 to 0.66; 2 studies, 382 adolescents, low-quality evidence), but not with overweight. Replacing packed school lunch with a nutrient-rich diet in addition to nutrition education did not improve mathematics (MD -2.18, 95% CI -5.83 to 1.47; scale range 0 to 69; SMD -0.26, 95% CI -0.72 to 0.20; 1 study, 76 children, low-quality evidence) and reading achievement (MD 1.17, 95% CI -4.40 to 6.73; scale range 0 to 108; SMD 0.13, 95% CI -0.35 to 0.61; 1 study, 67 children, low-quality evidence). AUTHORS' CONCLUSIONS Despite the large number of childhood and adolescent obesity treatment trials, we were only able to partially assess the impact of obesity treatment interventions on school achievement and cognitive abilities. School and community-based physical activity interventions as part of an obesity prevention or treatment programme can benefit executive functions of children with obesity or overweight specifically. Similarly, school-based dietary interventions may benefit general school achievement in children with obesity. These findings might assist health and education practitioners to make decisions related to promoting physical activity and healthy eating in schools. Future obesity treatment and prevention studies in clinical, school and community settings should consider assessing academic and cognitive as well as physical outcomes.

Abstract
PURPOSE This study aimed to examine the effects of an adolescent obesity management educational program (AOMEP) on middle and high school teachers. METHODS A quasiexperimental, pretest post-test design was performed to test primary variables, including adolescent obesity management knowledge, attitudes, perceived behavioral control, and behavioral intention based on the concepts presented in the Theory of Planned Behavior. RESULTS A total of 61 teachers participated. The experimental group (n = 30) received 15 hours of AOMEP, whereas the control group (n = 31) did not receive any. The experimental group showed significant improvement in knowledge (t = 2.53, d = .65, p = .014) and attitude (t = 2.77, d = .71, p = .008) toward adolescent obesity management compared to the control group. However, there were no significant differences in perceived behavioral control or behavioral intention between the groups. CONCLUSIONS AOMEP may be utilized as an effective obesity management program for adolescent students in schools.

Abstract
BACKGROUND The increasing prevalence of childhood obesity is - amongst other factors - due to changed leisure time habits with decreased physical activity and increased media consumption. However, electronic media such as tablets and smartphones might also provide a novel intervention approach to prevent obesity in childhood and adolescence. OBJECTIVES A summary of interventions applying electronic media to prevent childhood obesity is provided to investigate short term effects as well as long term results of these interventions. METHODS A systematic literature search was performed in PubMed/Web of Science to identify randomized and/or controlled studies that have investigated the efficacy of electronic media for obesity prevention below the age of 18. RESULTS A total of 909 studies were identified, and 88 studies were included in the analysis. Active video games did increase physical activity compared to inactive games when applied within a peer group. Interventions via telephone had positive effects on certain lifestyle-relevant behaviours. Interventions via mobile were shown to decrease dropout rates by sending regular SMS messages. To date, interventions via smartphones are scarce for adolescents; however, they might improve cardiorespiratory fitness. The results from internet-based interventions showed a trend towards positive effects on lifestyle-relevant behaviors. The combination of different electronic media did not show superior results compared to interventions with only one medium. Interventions via TV, DVD or video-based interventions may increase physical activity when offered as an incentive, however, effects on weight status were not observed. DISCUSSION Children and adolescents currently grow up in a technology- and media-rich society with computers, tablets, smartphones, etc. used daily. Thus, interventions applying electronic media to prevent childhood obesity are contemporary. Available studies applying electronic media are however heterogeneous in terms of applied medium and duration. Positive effects on body composition were not observed, but only on certain lifestyle-relevant behaviours. In addition, these effects could only be seen in the short term. Follow-up data are currently scarce.

Abstract
Abstract. The theory of planned behavior (TPB) is a prominent framework for predicting and explaining behavior in a variety of domains. The theory is also increasingly being used as a framework for conducting behavior change interventions. In this meta-analysis, we identified 82 papers reporting results of 123 interventions in a variety of disciplines. Our analysis confirmed the effectiveness of TPB-based interventions, with a mean effect size of .50 for changes in behavior and effect sizes ranging from .14 to .68 for changes in antecedent variables (behavioral, normative, and control beliefs, attitude, subjective norm, perceived behavioral control, and intention). Further analyses revealed that the interventions’ effectiveness varied for the diverse behavior change methods. In addition, interventions conducted in public and with groups were more successful than interventions in private locations or focusing on individuals. Finally, we identified gender and education as well as behavioral domain as moderators of the interventions’ effectiveness.

Abstract
Clinical trials have been slow to incorporate e-technology (digital and electronic technology that utilizes mobile devices or the Internet) into the design and execution of studies. In the meantime, individuals and corporations are relying more on electronic platforms and most have incorporated such technology into their daily lives. This paper provides a general overview of the use of e-technologies in clinical trials research, specifically within the last decade, marked by rapid growth of mobile and Internet-based tools. Benefits of and challenges to the use of e-technologies in data collection, recruitment and retention, delivery of interventions, and dissemination are provided, as well as a description of the current status of regulatory oversight of e-technologies in clinical trials research. As an example of ways in which e-technologies can be used for intervention delivery, a summary of e-technologies for treatment of substance use disorders is presented. Using e-technologies to design and implement clinical trials has the potential to reach a wide audience, making trials more efficient while also reducing costs; however, researchers should be cautious when adopting these tools given the many challenges in using new technologies, as well as threats to participant privacy/confidentiality. Challenges of using e-technologies can be overcome with careful planning, useful partnerships, and forethought. The role of web- and smartphone-based applications is expanding, and the increasing use of those platforms by scientists and the public alike make them tools that cannot be ignored.

Abstract
BACKGROUND Early adolescents perceive peers as credible and relatable. Peers therefore have a unique conduit to engage early adolescents in positive health behaviors through nutrition learning such as that recommended by the U.S. Institute of Medicine (IOM). PURPOSE We developed an online, peer leader component to an existing in-person preventive nutrition intervention called NutriBee. We reasoned that youth ages 13-18 could create intervention materials that could remain engaging, credible and relatable to younger peers ages 10-12 online. Peer leaders could potentially derive health benefits from their service-learning experience. METHODS From 2013-2014 youth could apply online to relate a personal interest to nutrition, an opportunity promoted at NutriBee pilot sites and through social media. The peer leaders with diverse backgrounds honed original ideas into tangible projects with the support of adult subject-matter experts chosen by the youth. Nutrition expertise was provided by NutriBee staff who then also converted the youth-invented projects from various media into an online curriculum. RESULTS 19 of 27 (70%) of selected youth from 12 states and diverse backgrounds, created an online curriculum comprising 10% of NutriBee's 20-hour intervention. All 19 online projects modeled 1 or more of NutriBee's 10 positive health behaviors; 8 evoked the chemosenses; 6 conveyed food texture; and 13 provided social context. Peer leaders perceived career advancement and service learning benefits. The dose, pedagogic approach, and project content align with the IOM recommendation. CONCLUSIONS Youth created intervention materials which communicate positive health behaviors online in ways peers can adopt. In a customarily sight-sound digital platform, youth leveraged the senses of smell, taste and touch and social context important for food selection. Peer leaders derived health benefit, as indirectly assessed by IOM criteria.

The influence of gender on colorectal cancer knowledge, screening intention, perceived risk and worry among African Americans in South Florida. J Community Health 2014; 39:230-8.

Abstract
The aim of this study was to examine if gender differences exist for colorectal cancer (CRC) knowledge, intention to screen, perceived risk and cancer worry among African Americans for CRC. African American males and females (N = 336) aged 45 years or older living in southeast Florida were recruited to participate in a cross-sectional survey that assessed intentions to screen as well as CRC knowledge, cancer worry, perceived risk. No significant differences were found between men and women in their intention to screen for CRC or in their worry about cancer. Results did suggest that men and women differed significantly about their understanding of CRC knowledge. Findings also showed that there were differences in perceived risk between genders, with female study participants possessing lower levels of risk than men. Study results suggest that future interventions need to ensure that females understand their risk for CRC and understand the benefits associated with CRC screening. Findings also suggest that interventions promoting CRC screening may need to be tailored if increased participation in CRC screening is to be achieved for women.
