Peer mentor versus teacher delivery of a physical activity program on the effects of BMI and daily activity: protocol of a school-based group randomized controlled trial in Appalachia

Randomised trial of Mentored 'Planning to be Active+Family' [MPBA+F] for Appalachian youth at risk for diabetes: virtual delivery protocol

Introduction

Obesity (OB) in children remains a national epidemic. This trial targets children suffering from overweight (OW) and OB living in rural Appalachia. Rural Appalachia is fraught with unhealthy behaviours, high rates of OB, pre-diabetes and type 2 diabetes among children. Diabetes prevalence in Appalachia is nearly double that of other regions. The prevalence of Appalachian children suffering from OB and extreme obesity (EO) increases the severity of diabetes.

Methods and analysis

We will conduct a stratified randomised-controlled trial to evaluate Mentored Planning to be Active+Family (MPBA+F) among seventh grade children with OW/OB/EO from rural Appalachian counties. Based on the Social Cognitive Theory, MPBA+F curriculum is a self-regulation approach to physical activity (PA) developed at The Ohio State University and successfully tested for feasibility in rural Appalachian middle schools. MPBA+F (a) incorporates active skill-building activities; (b) reinforces self-regulating activities; (c) engages in individual and group PA; (d) builds the link between PA, hydration and physical health and (e) actively supports weekly PA goals. Weekly skills are incorporated into reinforcement assignments verified at the beginning the following week. The primary outcome is the average daily minutes of moderate-vigorous PA. We will stratify by sex assigned at birth and conduct intent-to-treat analysis. We use descriptive statistics to summarise cohort and group (MPBA+F or comparison) baseline characteristics and examine variable distributions. Bivariate tests examine the balance of baseline characteristics by intervention groups. Mixed-effects linear modelling will be our more primary regression strategy. A potential problem is loss of curricular integrity. Our process assessment, structured mentor training and Instructor's Guide reduce this concern. Another concern may be the lack of reliable broadband access. Participating counties exceed 75% broadband access. Those who lose internet access may have materials mailed to their home or accessed on the study website.

Ethics and dissemination

This study was reviewed and approved by the American Diabetes Association Grants Review Committee (Grant number 11-22-ICTSN-30), the host institution's Social and Behavioral Human Subjects Review Committee (Protocol 2022B0149) and is registered on ClinicalTrials.gov (Protocol NCT05758441). All data that can be shared without compromising human subject protections will be shared to an approved open data repository within six months of publication or 18 months of the conclusion of the funding period (November 2025) if the study remains unpublished.

The impact of family and friend support of physical activity on the participation in physical activity within Indigenous individuals in Saskatoon

Introduction

Social support within Indigenous worldviews is recognized as a component of health and has been associated with physical activity and sedentary behaviour. Physical Activity (PA) is a modifiable behaviour that can help reduce risks of disease and benefit many dimensions of health. The purpose of this study was to compare the physical activity of Indigenous adults in Saskatchewan with and without family/friend support of PA.

Methods

The Family Influence on Physical Activity questionnaire was used to record the extent and forms of family/friend support of PA. The Godin Shepard Leisure Exercise Questionnaire (GSLEQ) was used to measure weekly PA, including moderate PA (MPA), vigorous PA (VPA), exercise frequency (WEF) and GSLEQ scores.

Results

Indigenous participants overall, First Nations and Cree participants specifically with family/friend involvement in PA reported greater weekly WEF and GSLEQ scores. Indigenous participants overall and First Nations participants specifically with family and friends who watch them engage in PA reported greater weekly VPA and GSLEQ scores. Among First Nations and Cree participants specifically, those with family/friends encouragement of PA reported greater weekly VPA, WEF and GSLEQ scores. Furthermore, First Nations participants with active family/friends reported significantly greater weekly VPA (36.8 ± 51.5 min·week-1 vs. 80.2 ± 108.5 min·week-1; p = 0.01). Greater weekly VPA was found in Métis participants with family/friend involvement in PA and with family/friends who watch them engage in PA (67.6 ± 59.6 min·week-1 vs. 29.5 ± 40.8 min·week-1; p = 0.01).

Discussion

Social support, specifically family/friends involvement, has a significant impact on Indigenous participation in PA.

Interventions to prevent obesity in children aged 12 to 18 years old

BACKGROUND

Prevention of obesity in adolescents is an international public health priority. The prevalence of overweight and obesity is over 25% in North and South America, Australia, most of Europe, and the Gulf region. Interventions that aim to prevent obesity involve strategies that promote healthy diets or 'activity' levels (physical activity, sedentary behaviour and/or sleep) or both, and work by reducing energy intake and/or increasing energy expenditure, respectively. There is uncertainty over which approaches are more effective, and numerous new studies have been published over the last five years since the previous version of this Cochrane Review.

OBJECTIVES

To assess the effects of interventions that aim to prevent obesity in adolescents by modifying dietary intake or 'activity' levels, or a combination of both, on changes in BMI, zBMI score and serious adverse events.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was February 2023.

SELECTION CRITERIA

Randomised controlled trials in adolescents (mean age 12 years and above but less than 19 years), comparing diet or 'activity' interventions (or both) to prevent obesity with no intervention, usual care, or with another eligible intervention, in any setting. Studies had to measure outcomes at a minimum of 12 weeks post baseline. We excluded interventions designed primarily to improve sporting performance.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our outcomes were BMI, zBMI score and serious adverse events, assessed at short- (12 weeks to < 9 months from baseline), medium- (9 months to < 15 months) and long-term (≥ 15 months) follow-up. We used GRADE to assess the certainty of the evidence for each outcome.

MAIN RESULTS

This review includes 74 studies (83,407 participants); 54 studies (46,358 participants) were included in meta-analyses. Sixty studies were based in high-income countries. The main setting for intervention delivery was schools (57 studies), followed by home (nine studies), the community (five studies) and a primary care setting (three studies). Fifty-one interventions were implemented for less than nine months; the shortest was conducted over one visit and the longest over 28 months. Sixty-two studies declared non-industry funding; five were funded in part by industry. Dietary interventions versus control The evidence is very uncertain about the effects of dietary interventions on body mass index (BMI) at short-term follow-up (mean difference (MD) -0.18, 95% confidence interval (CI) -0.41 to 0.06; 3 studies, 605 participants), medium-term follow-up (MD -0.65, 95% CI -1.18 to -0.11; 3 studies, 900 participants), and standardised BMI (zBMI) at long-term follow-up (MD -0.14, 95% CI -0.38 to 0.10; 2 studies, 1089 participants); all very low-certainty evidence. Compared with control, dietary interventions may have little to no effect on BMI at long-term follow-up (MD -0.30, 95% CI -1.67 to 1.07; 1 study, 44 participants); zBMI at short-term (MD -0.06, 95% CI -0.12 to 0.01; 5 studies, 3154 participants); and zBMI at medium-term (MD 0.02, 95% CI -0.17 to 0.21; 1 study, 112 participants) follow-up; all low-certainty evidence. Dietary interventions may have little to no effect on serious adverse events (two studies, 377 participants; low-certainty evidence). Activity interventions versus control Compared with control, activity interventions do not reduce BMI at short-term follow-up (MD -0.64, 95% CI -1.86 to 0.58; 6 studies, 1780 participants; low-certainty evidence) and probably do not reduce zBMI at medium- (MD 0, 95% CI -0.04 to 0.05; 6 studies, 5335 participants) or long-term (MD -0.05, 95% CI -0.12 to 0.02; 1 study, 985 participants) follow-up; both moderate-certainty evidence. Activity interventions do not reduce zBMI at short-term follow-up (MD 0.02, 95% CI -0.01 to 0.05; 7 studies, 4718 participants; high-certainty evidence), but may reduce BMI slightly at medium-term (MD -0.32, 95% CI -0.53 to -0.11; 3 studies, 2143 participants) and long-term (MD -0.28, 95% CI -0.51 to -0.05; 1 study, 985 participants) follow-up; both low-certainty evidence. Seven studies (5428 participants; low-certainty evidence) reported data on serious adverse events: two reported injuries relating to the exercise component of the intervention and five reported no effect of intervention on reported serious adverse events. Dietary and activity interventions versus control Dietary and activity interventions, compared with control, do not reduce BMI at short-term follow-up (MD 0.03, 95% CI -0.07 to 0.13; 11 studies, 3429 participants; high-certainty evidence), and probably do not reduce BMI at medium-term (MD 0.01, 95% CI -0.09 to 0.11; 8 studies, 5612 participants; moderate-certainty evidence) or long-term (MD 0.06, 95% CI -0.04 to 0.16; 6 studies, 8736 participants; moderate-certainty evidence) follow-up. They may have little to no effect on zBMI in the short term, but the evidence is very uncertain (MD -0.09, 95% CI -0.2 to 0.02; 3 studies, 515 participants; very low-certainty evidence), and they may not reduce zBMI at medium-term (MD -0.05, 95% CI -0.1 to 0.01; 6 studies, 3511 participants; low-certainty evidence) or long-term (MD -0.02, 95% CI -0.05 to 0.01; 7 studies, 8430 participants; low-certainty evidence) follow-up. Four studies (2394 participants) reported data on serious adverse events (very low-certainty evidence): one reported an increase in weight concern in a few adolescents and three reported no effect.

AUTHORS' CONCLUSIONS

The evidence demonstrates that dietary interventions may have little to no effect on obesity in adolescents. There is low-certainty evidence that activity interventions may have a small beneficial effect on BMI at medium- and long-term follow-up. Diet plus activity interventions may result in little to no difference. Importantly, this updated review also suggests that interventions to prevent obesity in this age group may result in little to no difference in serious adverse effects. Limitations of the evidence include inconsistent results across studies, lack of methodological rigour in some studies and small sample sizes. Further research is justified to investigate the effects of diet and activity interventions to prevent childhood obesity in community settings, and in young people with disabilities, since very few ongoing studies are likely to address these. Further randomised trials to address the remaining uncertainty about the effects of diet, activity interventions, or both, to prevent childhood obesity in schools (ideally with zBMI as the measured outcome) would need to have larger samples.

Hoosier Sport: a research protocol for a multilevel physical activity-based intervention in rural Indiana

Introduction

Currently, only 1 in 4 children in the U.S. engage in the recommended amount of physical activity (PA) and disparities in PA participation increase as income inequities increase. Moreover, leading health organizations have identified rural health as a critical area of need for programming, research, and policy. Thus, there is a critical need for the development and testing of evidence-based PA interventions that have the potential to be scalable to improve health disparities in children from under-resourced rural backgrounds. As such, the present study utilizes human-centered design, a technique that puts community stakeholders at the center of the intervention development process, to increase our specific understanding about how the PA-based needs of children from rural communities manifest themselves in context, at the level of detail needed to make intervention design decisions. The present study connects the first two stages of the NIH Stage Model for Behavioral Intervention Development with a promising conceptual foundation and potentially sustainable college student mentor implementation strategy.

Methods

We will conduct a three-phase study utilizing human-centered community-based participatory research (CBPR) in three aims: (Aim 1) conduct a CBPR needs assessment with middle school students, parents, and teachers/administrators to identify perceptions, attributes, barriers, and facilitators of PA that are responsive to the community context and preferences; (Aim 2) co-design with children and adults to develop a prototype multi-level PA intervention protocol called Hoosier Sport; (Aim 3) assess Hoosier Sport's trial- and intervention-related feasibility indicators. The conceptual foundation of this study is built on three complementary theoretical elements: (1) Basic Psychological Needs mini-theory within Self-Determination Theory; (2) the Biopsychosocial Model; and (3) the multilevel Research Framework from the National Institute on Minority Health and Health Disparities.

Discussion

Our CBPR protocol takes a human-centered approach to integrating the first two stages of the NIH Stage Model with a potentially sustainable college student mentor implementation strategy. This multidisciplinary approach can be used by researchers pursuing multilevel PA-based intervention development for children.

The Nexus of Sports-Based Development and Education of Mental Health and Physical Fitness

Physical inactivity has increased globally, particularly in developed nations. A high proportion of the human population is unable to meet the physical activity recommendation of the World Health Organisation due to hypertension, metabolic syndrome, obesity, and other medical conditions. Non-communicable diseases and mental health problems are becoming more prevalent, particularly in low and middle-income nations. This study aimed to determine the effectivenessof a mentorship programmeon university students' mental health and physical fitness. The intervention comprised the effects of sports-based development and education on physical fitness and mental health. A total of 196 and 234 students from two universities were randomly assigned to the intervention and control groups, respectively. The primary outcomes were engagement in physical activities (number of push-ups for 1 min, the strength of hand grip (kg), and the Jump test while standing (cm)), body fat proportion and psychological resilience, self-efficacy, and relationship with family and schoolmates. Participants in the control group had access to a web-based health education game, whereas the intervention group wassubjected to intensive interventional activities for one month based on the eight principles of the National Research Council and Institute of Medicine. Data were analysed using Analysis of Variance (ANOVA) to compare the physical and mental components between the intervention and control groups. Relative to baseline, all the physical health components (push-ups, sit-ups, and jump tests), psychological resilience, relationship with family members, and self-efficacy increased significantly in the intervention compared to the control group. Body fat composition was significantly reduced in the intervention when compared tothe control group. In conclusion, the mentorship programme effectively improved the participants' physical and psychological health and could be developed further for application in a larger population.

Empowering Community Leadership: Perspectives of Peer Mentors Facilitating a Food Pantry-Based Nutrition Education Program

Peer Mentors (PMs) are valuable health educators within food-insecure communities; however, little is known about PMs' perspectives and experiences after serving in their peer mentor role. Therefore, this qualitative study explored PMs' (n = 10) perceptions and analyzed data using thematic analysis based on descriptive phenomenology. Four themes emerged: (1) Successes and Struggles in Sharing Nutrition Knowledge; (2) Establishing a Conducive Learning Environment; (3) The Peer Mentor and Mentee Connection: Impact of Shared Experiences; (4) Empowerment of the Peer Mentor Experience. PMs have many advantages; however, more research is needed to evaluate the sustainability and efficacy of PMs within food-insecure communities.

School-based obesity prevention programs in rural communities: a scoping review

OBJECTIVE

The objective of this review was to examine existing literature and conceptually map the evidence for school-based obesity prevention programs implemented in rural communities, as well as identify current gaps in the literature.

INTRODUCTION

Pediatric obesity is a significant public health condition worldwide. Rural residency places children at increased risk of obesity. Schools have been identified as an avenue for obesity prevention in rural communities.

INCLUSION CRITERIA

We considered citations focused on children (5 to 18 years of age) enrolled in a rural educational setting. We included obesity prevention programs delivered in rural schools that focused on nutrition or dietary changes, physical activity or exercise, decreasing screen time, or combined nutrition and physical activity that aimed to prevent childhood obesity. We included all quantitative, qualitative, and mixed methods research designs, as well as text and opinion data.

METHODS

A search was conducted of published and unpublished studies in English from 1990 through April 2020 using PubMed, CINAHL Complete, ERIC, Embase, Scopus, Academic Search Premier, Cochrane Register of Controlled Trials, and ClinicalTrials.gov. Gray literature was also searched. After title and abstract review, potentially relevant citations were retrieved in full text. The full texts were assessed in detail against the inclusion criteria by 2 independent reviewers. Included citations were reviewed and data extracted by 2 independent reviewers and captured on a spreadsheet targeting the review objectives.

RESULTS

Of the 105 studies selected for full-text review, 72 (68.6%) were included in the final study. Most of the studies (n = 50) were published between 2010 and 2019 and were conducted in the United States (n = 57). Most studies included children in rural elementary or middle schools (n = 57) and targeted obesity prevention (n = 67). Teachers implemented the programs in half of the studies (n = 36). Most studies included a combination of physical activity and nutrition components (n = 43). Other studies focused solely on nutrition (n = 9) or physical activity (n = 9), targeted obesity prevention policies (n = 9), or other components (n = 8). Programs ranged in length from weeks to years. Overall, weight-related, physical activity-specific, and nutrition-specific outcomes were most commonly examined in the included citations.

CONCLUSIONS

Obesity prevention programs that focused on a combination of physical activity and nutrition were the most common. Multiple outcomes were examined, but most programs included weight-specific and health behavior-specific outcomes. The length and intensity of rural school-based obesity prevention programs varied. More research examining scientific rigor and specific outcomes of rural school-based obesity prevention programs is needed.

A Randomized Control Study on the Effectiveness of Holistic Health Practice Program on a Group of Baccalaureate Nursing Students

Background:

From adolescents transitioning into professional healthcare team members, nursing students need to face different kinds of challenges during their journey of nursing study. Are nursing students ready and prepared to take care of themselves before taking care of others?

Aim:

Few studies were found on the holistic health of nurses in Macao. This study aims to explore the health status of a group of first-year undergraduate nursing students and to investigate whether a holistic health practice program can enhance their holistic health, self-esteem, and self-efficacy after they participate in the program.

Methods:

A randomized control study was used. Students in both the experimental and control groups filled in an online pre-test questionnaire, which consisted of some demographic information and the following measurement tools including, the Health Promotion Lifestyle Profile-II (HPLP-II), the Self-Esteem Scale (ESTEEM), and the General Self-Efficacy Scale (GSES). The experimental participants had to undergo an additional 6-sessions program on holistic health practice. After the intervention, all participants in both groups were invited to complete an online post-test questionnaire, which was the same as the one used in pre-study.

Results:

Results showed that participants’ physical activity was the lowest score in 6 domains, followed by their health responsibility. On the other hand, their spiritual growth scored the highest. The study found that participants who had attended the holistic health practice program had significantly enhanced their holistic health, self-esteem, and self-efficacy.

Conclusion:

This study provided some ground data of the holistic health status of nursing students in Macao. It also demonstrated that the Holistic Health Practice Program is effective in promoting holistic health, self-esteem, and self-efficacy among junior nursing students.

Efficacy of "Mentoring to Be Active" on Weight Loss, Body Mass Index, and Body Fat among Obese and Extremely Obese Youth in Rural Appalachia

PURPOSE

This study compares the efficacy of a behavioral skills mentoring program (Mentored Planning to Be Active [MBA]) to a teacher-led program (Planning to Be Active [PBA]) for increasing physical activity in Appalachian teens on health outcomes (weight loss, body mass index (BMI), and body fat).

METHODS

Secondary analysis of a larger group-randomized controlled trial was conducted in 20 rural Appalachian schools. Descriptive Pearson correlations and multivariate analyses with between-subject effects were conducted. Effect sizes (ES) using Cohen's d and odds ratios (OR) with 95% confidence intervals were calculated.

FINDINGS

The obese MBA group lost 77.5% more weight by T3 compared to the PBA group; T2 was (F = 8.51, P = .000) and T3 was (F = 7.62, P = .000). ES was 0.34. OR = 1.45 (95% CI: 0.558-3.792) at T2 and OR = 3.32 (95% CI: 1.103-9.978) at T3. Extremely obese in the MBA group lost 80.0% more weight compared to the PBA group; T2 was (F = 5.23, P = .025) and at T3 (F = 6.33, P = .015) ES was 0.58. OR = 4.36 (95% CI: 0.981-19.34). Extremely obese females lost more weight compared to males (F = 4.75, P = .034). BMI and body fat had similar results; youth in the MBA group had the most improvement.

CONCLUSIONS

Rural Appalachian youth are disproportionately extremely obese. BMI does not capture adiposity or cardiovascular risk. BMI, BMI percentile, raw weight, fat mass, and percent body fat are more complete analyses of adiposity and cardiovascular risk.

Overcoming Challenges in Multisite Trials

BACKGROUND

Conducting multisite studies has many challenges, including determining the geographic distance between sites, ensuring effective communication, monitoring intervention and data integrity, handling institutional policy variations, seeking institutional review board approval with unique site needs or complex subcontracts, and planning for additional costs.

OBJECTIVES

This article discusses common challenges in conducting multisite studies and identifies strategies to overcome these challenges using real-world examples from the literature, the authors' research studies, and their personal experiences.

METHODS

A summary of articles on multisite trials conducted within the past 10 years was explored to uncover common challenges in conducting multisite trials. To enrich the context, exemplars from authors' works are included. Based on literature and experience, strategies to combat challenges are summarized.

RESULTS

Unique issues related to multisite studies include site selection, use of epicenters/coordinating centers, hiring/managing staff, fidelity monitoring, institutional review board approval, statistical considerations, and approaches to authorship.

CONCLUSION

Addressing challenges a priori can improve scientific rigor, reproducibility, and evidence from multisite studies. Given the benefits to scientific rigor, reproducibility, and design, findings from multisite studies are more likely to provide evidence to transform clinical practice and influence policy.

An evidence-based nutrition education programme for orphans and vulnerable children: protocol on the development of nutrition education intervention for orphans in Soweto, South Africa using mixed methods research

BACKGROUND

Focus on interventions for orphans and vulnerable children (OVC) in South Africa on education, quality of life (QoL) and nutrition-related matters have been reported diminutive. The risk of dropping out of school for an OVC with poor QoL and without varied food intake is very high. The problem with poor; QoL, nutritional care and academic performance (AP) of the OVC is that it sets the foundation for their adults' life. The purpose of this longitudinal study is to develop, implement and to test the efficacy of an evidence-based nutrition education programme (NEP) for OVC that will integrate their families/caregivers, schools and communities.

METHODS

A longitudinal study, and a mixed-methods approach steered by action research will be used. This study will be in three phases. Phase 1 will be the needs assessment; Phase 2 will be the development of nutritional education materials, and Phase 3 is the intervention. QoL, dietary intakes, body composition, and anthropometric status, physical activities, and AP of 520 OVC in Soweto will be assessed using standard techniques. Nutrition knowledge, attitude and practices (KAP) of the caregivers will be assessed using previously validated questionnaires. Focus group discussion (FGD) will be conducted to gain an in-depth understanding of what OVC eat and factors affecting their food intakes. Data will be collected at baseline, week 12 and week 24. Generalised Least Squares (GLS) regression model will be used to test the study hypotheses. Atlas-ti and Thematic Framework Analysis (TFA) will be used for qualitative data analysis.

DISCUSSION

This study will provide detailed information on the QoL, food intakes concerning academic performance and general well-being of OVC in an Africa setting. The participatory mixed methods nature of the study will provide valuable insights into the drivers and challenges to QoL, AP, and nutritional status of this group. This approach will assist the policymakers' and other stakeholders in decision making regarding the general well-being of the OVC.
