Harnessing technological solutions for childhood obesity prevention and treatment: a systematic review and meta-analysis of current applications

Examining Primary Care Utilization and Distance Traveled for Care Among Medicaid-Insured Children in South Carolina

To identify demographic and primary care utilization factors associated with distance traveled for healthcare among Medicaid-insured children in South Carolina (SC). Medicaid claims data was analyzed among patients with a weight-related diagnostic code who received primary care services in SC from 2018 to 2022 (N = 1,055,613). Multinomial regression analyses were used to examine associations between demographic and primary care utilization factors and distance traveled to primary care services. Among Medicaid-insured children in SC, those who were Non-Hispanic White, obese, had lapses in coverage, sought non-well-child visits, and lived in rural counties demonstrated higher odds of traveling for primary care, compared to other children. Further, children who were Non-Hispanic White, overweight, and had lapses in coverage demonstrated higher odds of traveling distally for PC, compared to other children. These findings underscore the complex interplay between race/ethnicity, healthcare access, and obesity risk among Medicaid-insured children, emphasizing the need for targeted interventions that address these disparities. The study's insights can inform policy and healthcare practices aimed at improving the accessibility of primary care and supporting effective weight management strategies for pediatric populations in SC.

2025 Heart Disease and Stroke Statistics: A Report of US and Global Data From the American Heart Association

BACKGROUND

The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2025 AHA Statistical Update is the product of a full year's worth of effort in 2024 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. This year's edition includes a continued focus on health equity across several key domains and enhanced global data that reflect improved methods and incorporation of ≈3000 new data sources since last year's Statistical Update.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Lifestyle risk factors for overweight and obesity among rural Indian adults: a community-based prospective cohort study

India's nutrition transition has led to an increased burden of overweight/obesity (body mass index of ≥23 kg/m2), driven by lifestyle factors like poor diet, inactivity, and substance use, prompting public health interventions. However, these interventions lack supporting evidence, especially in rural areas, hindering effective strategies for this population. To address this evidence gap, this study used cohort data (baseline: 2018-19, follow-up: 2022-23) from the Birbhum Population Project (West Bengal, India) to analyse lifestyle risk factors and their association with incidence and remission of overweight/obesity among adults aged ≥18 years (sample: 8,974). Modified Poisson regression model was employed to attain the study objective. From 2017-2018 to 2022-2023, the prevalence of overweight/obesity increased from 15.2% (95% CI: 14.1%-16.4%) to 21.0% (95% CI: 19.7%-22.3%) among men and from 24.1% (95% CI: 22.9%-25.2%) to 33.8% (95% CI: 32.5%-35.1%) among women. Overall, 23.0% (95% CI: 21.8%-24.3%) of adults experienced incidence of overweight/obesity, while 13.9% (95% CI: 12.4%-15.6%) experienced remission. Use of motor vehicles among unemployed participants was associated with incident overweight/obesity (relative risk or RR: 1.058; 95% CI: 1.023-1.095; P: 0.001). Vigorous activity at home (including gardening, yard work, and household chores) was linked to higher odds of recovering from overweight/obesity (RR: 1.065; 95% CI: 1.008-1.125; P: 0.025). Frequent tobacco use (often/daily vs. none) was inversely associated with remission of overweight-obesity (RR: 0.689; 95% CI: 0.484-0.980; P: 0.038), as was each 1 ml in alcohol consumption (RR: 0.995; 95% CI: 0.991-0.999; P: 0.022). Discouraging habitual motor vehicle use may help prevent overweight/obesity, while promoting home-based activities may aid remission, particularly for women who are at higher risk for overweight/obesity.

Families' Experiences With Family-Focused Web-Based Interventions for Improving Health: Qualitative Systematic Literature Review

BACKGROUND

eHealth interventions can favorably impact health outcomes and encourage health-promoting behaviors in children. More insight is needed from the perspective of children and their families regarding eHealth interventions, including features influencing program effectiveness.

OBJECTIVE

This review aimed to explore families' experiences with family-focused web-based interventions for improving health.

METHODS

Five databases were searched on October 26, 2022-updated on October 24, 2023-for studies reporting qualitative data on participating children or their caregivers' experiences with web-based programs. Study identification was performed in duplicate and studies were independently appraised for quality. Thematic synthesis was undertaken on qualitative data extracted from the results section of each included article.

RESULTS

Of 5524 articles identified, 28 articles were included. The studies examined the experiences of school-aged children (aged 5-18 years) and their caregivers (mostly mothers) with 26 web-based interventions that were developed to manage 17 different health conditions or influence health-supporting behaviors. Six themes were identified on families' experiences: connecting with others, agency of learning, program reputability or credibility, program flexibility, meeting participants' needs regarding program content or delivery, and impact on lifestyle.

CONCLUSIONS

Families positively perceived family-focused web-based interventions, finding value in quality connections and experiencing social support; intervention features aligned with behavioral and self-management principles. Key considerations were highlighted for program developers and health care professionals on ways to adapt eHealth elements to meet families' health-related needs. Continued research examining families' experiences with eHealth interventions is needed, including the experiences of families from diverse populations and distinguishing the perspectives of children, their caregivers, and other family members, to inform the expansion of family-focused eHealth interventions in health care systems.

The effectiveness of a 10-week family-focused e-Health healthy lifestyle program for school-aged children with overweight or obesity: a randomised control trial

BACKGROUND

Electronic health (e-Health) interventions may increase effectiveness and address limitations of conventional in-person childhood obesity treatment programs. This study evaluates the effectiveness of a 10-week e-Health (web-based) healthy lifestyle program for school-aged children with overweight/obesity.

METHODS

In this randomised control trial (RCT), families with children aged 7-13 years with overweight/obesity (body mass index, BMI ≥ 85th percentile), living in Victoria, Australia, were recruited. Families were randomised to intervention or waitlist control and received the 10-week web-based program. The primary outcome was the change in children's BMI z-score over 10 weeks. Other outcomes included change in children's waist circumference, dietary intake, physical activity, and quality of life over 10 weeks.

RESULTS

Of 148 children (125 families) recruited, 102 children (85 families) completed the RCT. A significant decrease in children's BMI z-scores was observed in the intervention compared to the control group over 10 weeks (mean difference 0.11; 95% CI, 0.02-0.20). The web-based program was also effective in improving children's quality of life and lifestyle behaviour changes over 10 weeks. In the intervention group, there was a significant increase in children's quality of life scores (intervention versus control: median change (IQR) = 11 (3, 17) versus 1 (-3, 7); p = 0.034), overall diet quality scores (6 (2, 10) versus 2 (-3, 5); p < 0.001), and daily physical activity levels (5.2 (-2.6, 12.8) versus - 0.2 (-8.2, 4.5); p = 0.022) compared to the control group.

CONCLUSIONS

A web-based healthy lifestyle program effectively improved short-term health-related outcomes in children with overweight/obesity. Further research is needed to identify determinants of program effectiveness, evaluate sustained effects, and equitably tailor childhood obesity e-Health interventions to diverse populations.

Employing a Phased, Interdisciplinary Approach Across Healthcare and School Settings: mHealth Adaptations for Youth with Autism Spectrum Disorder At-Risk of Experiencing Obesity

Youth with autism spectrum disorder (ASD) are at nearly twice the risk of experiencing obesity, compared to youth without ASD. Wellness Education to Create Healthy habits and Actions to Thrive (WE CHAT) is a novel chatbot that engages participants to enhance primary care delivery and associated care coordination services through mobile health (mHealth) technology focused on social determinants of health (SDOH) and social-emotional health. This study examines multiple perspectives regarding the development and implementation of innovative mHealth technology among youth with ASD. The phases of this study include (1) discussion among individuals and parents of children with ASD, (2) in-depth interviews with primary care providers (PCPs) who treat youth with ASD, and (3) in-depth interviews with interdisciplinary rehabilitation providers who treat youth with ASD. Phases 1 and 2 employed rapid qualitative analysis, and Phase 3 involved inductive thematic analysis to provide context to gaps identified in prior phases. Key themes across the three phases included the variability of symptoms among individuals with ASD, the differences in perceived value of mHealth technology, the importance of family-centered care, and the role of interdisciplinary support. Participants recommended the development of branching logic to increase the flexibility of mHealth technology designed for youth with ASD. This study gathered insight from multiple perspectives to identify opportunities for supporting independent participation in mHealth technology while reducing associated caregiver burden among youth with ASD. These findings may inform refinement and expansion of WE CHAT for patients with varying health needs.

Relevance and Acceptability of a Technology-delivered Childhood Obesity Intervention for Hispanic/Latino Families in Rural Nebraska: A Qualitative Approach

BACKGROUND

Hispanics/Latinos (H/L) are the largest minority group in rural areas in the United States. Although childhood obesity represents a growing burden for this population, there is a lack of culturally relevant interventions designed for Latino children and their families.

OBJECTIVE

This study evaluates the relevance and acceptability of Hispanic Family Connections, a technology-delivered and family-based childhood obesity prevention program for Hispanic/Latino families in rural Nebraska. The program's materials include a workbook with activities for home completion and interactive voice response (IVR) calls.

METHODS

A qualitative exploratory study was developed through Focus Groups. Participants were adults who self-identified as H/L, caregivers to children aged 6 to 12, and Spanish literate. A bilingual mediator used a script with 12 questions, based on the project's conceptual and methodological frameworks: i-PARIHS, Cultural Relevance Questionnaire, and FRAME. We used PowerPoint presentations to share samples of the materials that comprise the Hispanic Family Connection intervention. Sessions were recorded, and we applied thematic content analysis with the support of a codebook based on the constructs of Innovation, Facilitation, Beneficiaries, and Adaptations.

RESULTS

Twenty-six H/L who lived in rural Nebraska participated in 8 Focus Groups (FG). We conducted 7 FG in Spanish and 1 in English. Participants highlighted the program's delivery mode using automated personalized technology, which could give them more freedom to engage. They considered the images and wording culturally relevant and easy to understand. Also, the involvement of all family members was a positive note, with parents working as role models. Factors such as workload and weather conditions could act as barriers to participation.

CONCLUSION

Overall, the intervention was considered relevant among rural Hispanic/Latinos, and the program design and materials were accepted with few adaptations suggested.

Interventions to prevent obesity in the first 1000 days: scoping review

Introduction

The global prevalence of childhood obesity is a public health challenge. Early intervention, including during pregnancy, is essential to prevent this health problem.

Objective

Identify and characterize interventions during the first 1000 days of life that effectively prevent overweight and obesity.

Materials and Methods

A scoping review was carried out following the methodology proposed by Arksey and O'Malley. SCOPUS, EBSCOHost and PubMed databases were searched to select relevant articles. The analysis focused on articles published between January 2012 and December 2022.

Results

Fourteen articles with 10 interventions were included. These interventions were implemented in high-income countries and in racial and ethnic groups. Three interventions, involving 1013 women and their children, reported significant effects on preventing overweight and obesity at 18 and 24 months of the child's life.

Discussion

The interventions were characterized as multi-component, educational and based on theories of behavior change, parenting and sensory feeding. They addressed risk factors such as breastfeeding, complementary feeding, physical activity and sleep. There is an increasing use of digital technology in their delivery.

Conclusion

Promising results have been found for the prevention of obesity in the early years of life; therefore, implementation of interventions in low- and middle-income countries is of paramount importance.

Innovative Strategies for Addressing Adolescent Health in Primary Care Through Telehealth

With recent gains in telehealth access across health sectors, this editorial explores adolescent-specific health issues where innovative use of virtual care is improving outcomes and access for adolescents. These include contraception, obesity, gender-affirming care, mental health, and eating disorder care. Clinicians caring for adolescents should be aware of advances in this field to maximize opportunities for their patients to receive evidence-based care in a manner that supports health equity and confidentiality concerns while understanding the evolving regulatory landscape of telehealth.

A family-based and mobile-assisted intervention for lifestyle behaviors in youths: A randomized controlled trial

This randomized controlled trial was conducted to assess the effectiveness of a family-based and mobile-assisted lifestyle intervention in reducing weight gain among school-age children with overweight and obesity. A total of 164 school-age children with overweight or obesity and their parents were randomized to the treatment intervention (n = 82) or an attention-control group (n = 82). The treatment intervention included three face-to-face education sessions, augmented by monthly text messages sent to parents on their mobile devices. The primary outcome was child BMI-for-age z-score. Secondary outcomes included child BMI, percent body fat, and actigraphy-assessed sleep as well as parental sleep quality. Outcomes were assessed at baseline, 3, 6, and 12 months after the intervention, with treatment effects analyzed using general linear models for repeated measures. Our results showed that children in the treatment intervention group had significantly lower BMI-for-age z score, BMI, and percent body fat than did those in the control group, with an adjusted mean difference of 0.31 units (95% CI: -0.59 to -0.03; p = 0.03), 1.34 kg/m² (95% CI, -2.42 to -0.26; p = 0.01), and 3.12% (95% CI, -5.93 to -0.30; p = 0.03), respectively. No treatment effects were observed for child and parental sleep. Our findings suggest that family-based and mobile-assisted lifestyle intervention results in significant and sustained benefits to enhanced weight management for school-age children with overweight and obesity. Nurses planning and delivering childhood overweight and obesity treatment interventions should consider a family-based approach with the assistance of mobile devices.

Randomized Clinical Trial to Increase Self-Monitoring of Physical Activity and Eating Behaviors in Youth: A Feasibility Study

Introduction

Mobile health (mHealth) has the potential to reduce reliance on in-person healthcare visits, making monitoring of health, eating, and physical activity less burdensome. There is a great need to develop and test mHealth tools for pediatric weight loss programs to enhance clinical practice. This study aimed to test the feasibility of utilizing a tailored suite of mHealth components to augment an existing evidence-based in-person pediatric weight management program.

Method

Using a two-group randomized superiority trial design, participants who completed baseline measurement were randomized to Brenner Families in Training (Brenner FIT) or Brenner FIT + mHealth (Brenner mFIT)), and follow-up measures were completed at 3 and 6 months. Feasibility was assessed in terms of screening, recruitment, randomization, retention, and the assessment process. Acceptability was assessed in terms of program completion and implementation fidelity was assessed in terms of logging activity, frequency of self-monitoring, goal setting, and retention rate.

Results

Overall, 173 dyads were eligible for enrollment based on inclusion criteria. Twenty-five dyads consented to participate. Sixteen dyads completed baseline psychosocial questionnaires, eight dyads completed at least two 24-hour dietary recalls, and 20 (youth) participants returned accelerometers. Of the 14 dyads who completed enrollment, 7 dyads were each randomized into the intervention and control groups, with 10 and 5 dyads retained at three and six months, respectively. A total of four caregivers and two youth who utilized the website for goal setting set at least one goal, all seven youth linked their activity tracker, and most downloaded at least one video (two youth) or podcast (six caregivers).

Conclusions

Our results suggest that the assessment protocol was overly burdensome, the intervention had low acceptability, and the study as designed was not feasible to complete. Future studies should evaluate barriers and facilitators to the uptake of mHealth.

The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Significant effects of childhood obesity treatment with a web-based component in a randomised controlled study (Web-COP)

AIM

We evaluated the effect on body mass index standard deviation score (BMI-SDS) of a combined treatment (Web-COP) for children with obesity, including a web-based component targeting their parents.

METHODS

This randomised controlled trial recruited children 5-12 years of age with obesity (International Obesity Task Force BMI [IOTF-BMI] ≥30 kg/m2 ) from school health care and outpatient paediatric clinics in in Northern Sweden from 1 June 2019 to 21 June 2020. The children were randomised to Web-COP, an intervention with group sessions and a 12-week web-based component, or standard care. The primary outcome was the change in IOTF BMI-SDS after 6 months.

RESULTS

In total, 75 children (33 girls), mean age 9.5 years, were randomised, and 65/75 (87%) children and their parents completed the study, 35/39 (90%) in the Web-COP intervention and 30/36 (83%) in the standard care group. BMI-SDS at 6 months was changed from 3.08 to 2.81 in the intervention group compared to an increase from 3.07 to 3.16 in the standard care group, representing a significant difference between groups (p < 0.001). In the intervention group, 14/30 (47%) reduced their BMI-SDS ≥0.25, compared to none in the standard care group.

CONCLUSION

The parent-focused intervention significantly improved BMI-SDS in children with obesity as compared to children in standard care.

Integration of e-Health Strategies for Post-COVID-19 Pandemic Pediatric Weight Management Programs

Background: The COVID-19 pandemic catalyzed a renewed urgency to address the obesity pandemic and accelerated the use of technology to treat pediatric obesity. Yet, there are significant incongruities between the existing literature on technology for obesity management and the current health care system that may lead to suboptimal outcomes and increased costs. This study reviewed the types of e-health strategies currently in use, highlighted inconsistencies and overlap in terminology, and identified future research directions in e-health for childhood obesity, including gaps in implementation science. Methods: This narrative literature review synthesized seminal articles from the literature, as well as recent articles, using PubMed and Google Scholar that focused on the use of technology in treating pediatric obesity. This inclusive strategy was intended to elucidate the heterogeneity in how different disciplines are using digital health terminology in pediatric obesity research. Results: Both the prevalence of e-health interventions and its associated terminology are increasing in the peer-reviewed literature, especially since the beginning of the COVID-19 pandemic. Yet, their definitions and usage are unstandardized, leading to a lack of cohesion in the research and between disciplines. There is a gap in implementation science outcomes, including reimbursement, that may significantly impact external validity and uptake. Conclusion: A more systematic and precise approach to researching e-health that can assess specific technologies and combinations of technologies, their short-term and long-term effect sizes, and feasibility can produce the necessary data that may lead to reimbursement policies and, ultimately, improved pediatric weight management outcomes.

Parenting Styles and Psychosocial Factors of Mother-Child Dyads Participating in the ENDORSE Digital Weight Management Program for Children and Adolescents during the COVID-19 Pandemic

Childhood obesity is a complex disease with multiple biological and psychosocial risk factors. Recently, novel digital programs were developed with growing evidence for their effectiveness in pediatric weight management studies. The ENDORSE platform consists of mobile applications, wearables, and serious games for the remote management of childhood obesity. The pilot studies included 50 mothers and their children aged 6-14 years and resulted in a clinically significant BMI z-score reduction over 4 to 5 months. This secondary analysis of the ENDORSE study focuses on parenting styles and psychosocial factors.

METHODOLOGY

Semi-structured clinical interviews were conducted with all participating mothers pre-and post-intervention. The Parenting Styles and Dimensions Questionnaire (PSDQ) evaluated the mothers' parenting styles. The psychosocial functioning of the participating children was assessed with the parental version of the Strengths and Difficulties Questionnaire (SDQ). The relationship between parenting styles, psychosocial parameters, and weight outcomes was investigated using a linear regression analysis.

RESULTS

Weight-related stigma at school (56%), body image concerns (66%), and difficulties in family relationships (48%) were the main concerns documented during the initial psychological interviews. According to the SDQ, there was a significant decrease in children's conduct problems during the study's initial phase (pre-pilot group). A decrease in maternal demandingness (i.e., strict parenting style) was associated with a decrease in BMI z-score (beta coefficient = 0.314, p-value = 0.003).

CONCLUSION

Decreasing parental demandingness was associated with better weight outcomes, highlighting the importance of assessing parenting factors in pediatric weight management programs.

Effectiveness of utilizing step-monitoring devices to prevent and treat obesity in children and adolescents: A systematic review and meta-analysis

Background

Children and adolescents who are overweight and obese represent a growing public health issue. The use of step-monitoring devices as an intervention tool may be a simple, cost-effective, and easily replicable solution for addressing obesity in children and adolescents. No prior systematic reviews have evaluated the effectiveness of utilizing step-monitoring devices as an intervention method for obesity in children and adolescents.

Methods

Previous studies on using step-monitoring devices to prevent and treat obesity in children and adolescents were identified in the following databases: Web of Science, EMBASE, PubMed, Cochrane Library, SPORTDiscus, and SCOPUS. The search period for each database ranged from the year of their inception to 8 March 2023 (updated in June 2024). Meta-analyses were performed for mean differences (MDs) in body mass index (BMI), BMI z-score (BMI-Z), body fat, waist circumference, and body weight.

Results

From 12,907 relevant records, 23 studies were included in this meta-analysis. The included studies were mainly at low risk of bias, except for blinding. Step-monitoring device-based interventions had significant effects in reducing BMI-Z (MD -0.06; 95% CI -0.10 to -0.02), body fat (MD -0.95%; 95% CI -1.35 to -0.54), and body weight (MD -1.23 kg; 95% CI -2.36 to -0.10). However, there was no significant effect on BMI (MD -0.16 kg/m2; 95% CI -0.55 to 0.22) and waist circumference (MD -0.33 cm; 95% CI -1.23 to 0.58). Subgroup analyses indicated that participants who were overweight or obese showed greater intervention effects on BMI and BMI-Z compared to participants with normal weight. The programs with an intervention duration of ≤6 months presented a greater intervention effect on BMI-Z than those with an intervention duration of more than 6 months. The programs that established goals had a greater intervention effect on body fat than those that did not.

Conclusions

Step-monitoring devices may be an effective and generalizable intervention tool for the prevention and treatment of obesity in children and adolescents. Future studies should further explore how to set step goals and the duration of interventions to achieve better intervention effects.

An umbrella review of the benefits and risks associated with youths' interactions with electronic screens

The influence of electronic screens on the health of children and adolescents and their education is not well understood. In this prospectively registered umbrella review (PROSPERO identifier CRD42017076051 ), we harmonized effects from 102 meta-analyses (2,451 primary studies; 1,937,501 participants) of screen time and outcomes. In total, 43 effects from 32 meta-analyses met our criteria for statistical certainty. Meta-analyses of associations between screen use and outcomes showed small-to-moderate effects (range: r = -0.14 to 0.33). In education, results were mixed; for example, screen use was negatively associated with literacy (r = -0.14, 95% confidence interval (CI) = -0.20 to -0.09, P ≤ 0.001, k = 38, N = 18,318), but this effect was positive when parents watched with their children (r = 0.15, 95% CI = 0.02 to 0.28, P = 0.028, k = 12, N = 6,083). In health, we found evidence for several small negative associations; for example, social media was associated with depression (r = 0.12, 95% CI = 0.05 to 0.19, P ≤ 0.001, k = 12, N = 93,740). Limitations of our review include the limited number of studies for each outcome, medium-to-high risk of bias in 95 out of 102 included meta-analyses and high heterogeneity (17 out of 22 in education and 20 out of 21 in health with I2 > 50%). We recommend that caregivers and policymakers carefully weigh the evidence for potential harms and benefits of specific types of screen use.

An evidence gap map of interventions for noncommunicable diseases and risk factors among children and adolescents

Substance misuse, obesity, mental health conditions, type 1 diabetes, cancers, and cardiovascular and chronic respiratory diseases together account for 41% of disability-adjusted life years linked to noncommunicable diseases (NCDs) among children and adolescents worldwide. However, the evidence on risk factors and interventions for this age group is scarce. Here we searched four databases to generate an evidence gap map of existing interventions and research gaps for these risk factors and NCDs. We mapped 159 reviews with 2,611 primary studies; most (96.2%) were conducted in high-income countries, and only 100 studies (3.8%) were from low- and middle-income countries (LMICs). The efficacy of therapeutic interventions on biomarkers and adverse events for NCDs appears to be well evidenced. Interventions for mental health conditions appear to be moderately evidenced, while interventions for obesity and substance misuse appear to be moderate to very low evidenced. Priority areas for future research include evaluating digital health platforms to support primary NCD prevention and management, and evaluating the impact of policy changes on the prevalence of obesity and substance misuse. Our findings highlight the wide disparity of evidence between high-income countries and LMICs. There is an urgent need for increased, targeted financing to address the research gaps in LMICs.

Validation of remote assessment of preschool children's anthropometrics and motor skills

Introduction

Remotely delivered treatment and research procedures were rapidly adopted in response to the COVID-19 pandemic. However, it is unclear if these measures are valid. The purpose of this study was to compare the validity of anthropometry and motor skill proficiency measurements collected in a remote-setting to in-person setting among a sample of children ages 3-4 years.

Methods

Child anthropometry and motor skill performance were measured in-person by trained assessors and by parents at home with remote supervision via videoconference by trained assessors. The following measures from the National Institutes of Health Toolbox were collected: anthropometry (height and weight), manual dexterity/manipulation (9-hole pegboard), motor coordination and agility (supine timed up and go), lower body strength (standing long jump), and postural stability (one-leg standing balance). Differences in expert and parent-based measurements were assessed using Bland-Altman plots, paired samples t-tests, and Pearson correlations.

Results

A total of n = 14 children completed the assessments. No significant differences were observed between measurement locations for weight and motor skills (p > .05). Remote measurement of height (M = 101.1 cm, SD = 5.40) was significantly greater than in-person measurements (M = 98.2 cm, SD = 5.16); p < .0001.

Discussion

Remote measurements of motor skills and weight are valid assessments for researchers and clinicians to utilize in young children. Remote assessment with guidance offers comparable and valid estimates as in-person assessment, potentially offering a solution to resource-constricted barriers in research and access to care. There is an opportunity for researchers to fine-tune remote height and individual-level assessment strategies.

Evaluating a 10-Week Family-Focused E-Health Healthy Lifestyle Program for School-Aged Children with Overweight or Obesity: A Randomized Controlled Trial Study Protocol

E-Health childhood obesity treatment interventions may serve as favorable alternatives to conventional face-to-face programs. More studies are needed to evaluate the effectiveness of such interventions beyond immediately post-program completion, including exploring program features impacting effectiveness. This randomized controlled trial with a qualitative component and waitlisted control group will evaluate the effectiveness of a 10-week family-focused e-Health program for school-aged children with overweight/obesity and explore the experience of families completing the program. The primary outcome is the change in BMI z-score and will be assessed from baseline to 10 weeks. Secondary outcomes include (the change in) waist circumference, dietary intake, physical activity, quality of life, and experiences, and will be assessed at baseline, post-10 weeks, and/or immediately, 3-, 6-, and/or 12-months post-program completion. Independent t-tests will be used to compare the differences in means and analyses of variances (ANOVAs) will be conducted to investigate the impact of the program or of being waitlisted and the effect size of the program on quantitative outcome measures. Reflexive thematic analysis will be used with qualitative data. Findings from this study are expected to provide learnings to upscale conventional childhood obesity treatment services, in the hopes of curbing the rising rate of childhood obesity.

The Impact of the ENDORSE Digital Weight Management Program on the Metabolic Profile of Children and Adolescents with Overweight and Obesity and on Food Parenting Practices

Childhood obesity is a serious public health problem worldwide. The ENDORSE platform is an innovative software ecosystem based on Artificial Intelligence which consists of mobile applications for parents and health professionals, activity trackers, and mobile games for children. This study explores the impact of the ENDORSE platform on metabolic parameters associated with pediatric obesity and on the food parenting practices of the participating mothers. Therefore, the metabolic parameters of the 45 children (mean age: 10.42 years, 53% girls, 58% pubertal, mean baseline BMI z-score 2.83) who completed the ENDORSE study were evaluated. The Comprehensive Feeding Practices Questionnaire was used for the assessment of food parenting practices. Furthermore, regression analysis was used to investigate possible associations between BMI z-score changes and changes in metabolic parameters and food parenting practices. Overall, there was a statistically significant reduction in glycated hemoglobin (mean change = −0.10, p = 0.013), SGOT (mean change = −1.84, p = 0.011), and SGPT (mean change = −2.95, p = 0.022). Emotional feeding/food as reward decreased (mean change −0.21, p = 0.007) and healthy eating guidance increased (mean change = 0.11, p = 0.051). Linear regression analysis revealed that BMI z-score change had a robust and significant correlation with important metabolic parameters: HOMA-IR change (beta coefficient = 3.60, p-value = 0.046), SGPT change (beta coefficient = 11.90, p-value = 0.037), and cortisol change (beta coefficient = 9.96, p-value = 0.008). Furthermore, healthy eating guidance change had a robust negative relationship with BMI z-score change (beta coefficient = −0.29, p-value = 0.007). Conclusions: The Endorse digital weight management program improved several metabolic parameters and food parenting practices.

An analysis of current obesity strategies for adolescents in NSW against best practice recommendations: Implications for researchers, policymakers and practitioners

ISSUE ADDRESSED

Obesity is a significant health challenge facing adolescents. There is a critical need for government action to support all adolescents to improve risk factors for obesity. This study critically appraised initiatives, guidelines and policies (termed "strategies") from local health districts (LHDs), speciality health networks and Primary Health Networks (PHNs) across New South Wales (NSW), relevant to the prevention and management of obesity amongst adolescents and compare these to best practice recommendations.

METHODS

We critically appraised strategies against best practice recommendations that included support, access, responsiveness to needs, supportive environment, monitoring and evaluation and health equity. Strategies were collected by systematically searching websites of 15 LHDs, one speciality health network and 10 PHNs.

RESULTS

There was evidence of strategies regarding adolescent obesity prevention and management across all best practice recommendations. There was limited evidence of adolescent consumer participation, digital strategies for health services and online health information. There were minimal targeted public or school-based education campaigns and interventions on physical activity or nutrition. Place-based approaches such as sports and recreation facilities were not included in policies regarding the sale of healthy food and drinks. Evaluation evidence across all strategies was minimal.

CONCLUSIONS

Numerous strategies are being implemented across NSW to address adolescent obesity. Despite this, the alignment of strategies with best practice recommendations is poor and evidence of progress in tackling adolescent obesity remains unclear. SO WHAT?: Opportunities to generate and translate best practice evidence within government strategies for obesity must be prioritised with embedded measurement and evaluation plans.

The ENDORSE Feasibility Study: Exploring the Use of M-Health, Artificial Intelligence and Serious Games for the Management of Childhood Obesity

Childhood obesity constitutes a major risk factor for future adverse health conditions. Multicomponent parent-child interventions are considered effective in controlling weight. Τhe ENDORSE platform utilizes m-health technologies, Artificial Intelligence (AI), and serious games (SG) toward the creation of an innovative software ecosystem connecting healthcare professionals, children, and their parents in order to deliver coordinated services to combat childhood obesity. It consists of activity trackers, a mobile SG for children, and mobile apps for parents and healthcare professionals. The heterogeneous dataset gathered through the interaction of the end-users with the platform composes the unique user profile. Part of it feeds an AI-based model that enables personalized messages. A feasibility pilot trial was conducted involving 50 overweight and obese children (mean age 10.5 years, 52% girls, 58% pubertal, median baseline BMI z-score 2.85) in a 3-month intervention. Adherence was measured by means of frequency of usage based on the data records. Overall, a clinically and statistically significant BMI z-score reduction was achieved (mean BMI z-score reduction -0.21 ± 0.26, p-value < 0.001). A statistically significant correlation was revealed between the level of activity tracker usage and the improvement of BMI z-score (-0.355, p = 0.017), highlighting the potential of the ENDORSE platform.

Heart Disease and Stroke Statistics-2023 Update: A Report From the American Heart Association

BACKGROUND

The American Heart Association, in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The American Heart Association, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2023 Statistical Update is the product of a full year's worth of effort in 2022 by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. The American Heart Association strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional COVID-19 (coronavirus disease 2019) publications, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Dynamo Kids!/¡Niños Dinámicos! A Web Site for Pediatric Primary Care Providers to Offer Parents of Children 6-12 Years Old With Overweight and Obesity: Web Site Development and Protocol for Pilot Study

INTRODUCTION

A self-guided web site offered by pediatric primary care providers could help parents implement healthy behaviors.

METHOD

The Dynamo Kids/¡Niños Dinámicos program was developed with input from parents and health care professionals, creating a bilingual site for parents to learn why and how to implement healthy behavior changes for their children. A single-arm pilot will enroll parents with children 6-12 years with body mass index (BMI) ≥ 85th percentile seen in safety-net practices. Electronic health record modifications alert providers to eligible children at well-child encounters. Consented parents complete online surveys before accessing the site. At 3 months, the providers see children in weight-focused encounters. Outcomes include change in Family Nutrition and Physical Activity parent survey score (primary) and change in child relative BMI (secondary). Additional data include time spent on site, provider surveys, and provider and parent interviews.

RESULTS

Pending implementation.

DISCUSSION

If program shows promise, a large, controlled study could further evaluate with a goal of broad dissemination.

Parents' Experiences Using Digital Health Technologies in Paediatric Overweight and Obesity Support: An Integrative Review

This study aimed to explore parents' perspectives regarding the use of digital health technologies in paediatric overweight and obesity weight support. A systematic search in 'Academic Search Premier', 'British Nursing Index', 'Cumulative Index to Nursing and Allied Health', and 'Health Research Premium Collection' was conducted in November 2021. Inclusion criteria were English or Nordic peer-reviewed articles published after 2010, overweight and obese children aged 2-10, weight support using digital health technologies, and parental experiences examined. An integrative review was conducted using Joanna Briggs Institute quality appraisal checklists and a constant comparison analysis method. In total, 14 articles were analysed that included SMS, telephone, apps, websites, and social media as the main technology groups. A limitation of this review was the heterogenicity of the studies. The results indicate that parents, mostly mothers, had a positive experience, finding technologies helpful and easy to use, and expressed optimism toward future use. An option for interacting with others and the possibility of personalising support were enjoyed or requested. In conclusion, digital health technologies can be a suitable tool to empower the parents of children with overweight and obesity concerns, whose perspective should be considered during the design and support phases.

Process and effect evaluation of the app-based parenting program Samen Happie! on infant zBMI: A randomized controlled trial

Background

Although energy balance-related parenting practices are regarded critical components in the prevention of childhood obesity, most programs targeting parenting practices with respect to a wide range of energy balance-related behaviors were not aimed at high-risk families with a lower socioeconomic position (SEP).

Objective

The Samen Happie! app-based program aimed to stimulate healthy child weight development especially among families with a lower SEP, by encouraging healthy energy balance-related parenting practices.

Methods

A two-armed randomized controlled trial examined the process and effectiveness of the Samen Happie! program on child zBMI outcomes at 6- and 12-months follow-up. In total, 357 Dutch parents with infants aged 5-15 months old at baseline participated. Parents in the app condition (n = 179) received access to the Samen Happie! app and were compared to a waitlist-control condition (n = 178). Changes in zBMI were examined through linear mixed-effects models based on intention-to-treat and exploratory per-protocol principles.

Results

Process data showed low levels of sustained app use and moderate app acceptability. A general increase in child zBMI was observed in both conditions after 6 and 12 months. Intention-to-treat analyses using multiple imputations showed several statistically significant differences between conditions and high-risk subgroups. Specifically, at 6-months follow-up, zBMI increase was least pronounced in the app condition among children of parents with lower educational level. These findings were supported by exploratory per-protocol analyses including only frequent app users. In addition, per-protocol analyses showed benefits of app use at 6-months follow-up for children of parents with higher BMI. However, these effects were reversed at 12-months follow-up in both intention-to-treat and per-protocol analyses, where children of parents in the app condition in general increased the most in zBMI.

Conclusions

This study suggests that the Samen Happie! program might prevent zBMI increases after 6 months among children of parents with lower educational level, and children of parents with higher BMI who more frequently use the app. However, the app did not prevent increases in zBMI after 12 months. Future research should investigate strategies to increase sustained app use and engagement in mHealth parenting programs for childhood obesity as well as options to combine app-based programs with additional support strategies aimed at high-risk families.

Needs and Demands for e-Mental Health Interventions in Individuals with Overweight and Obesity: User-Centred Design Approach

INTRODUCTION

Several studies indicate an association between mental disorders and overweight or obesity. E-Mental health interventions offer an effective way to overcome barriers to health care access for individuals with overweight and obesity. The objective of this study was to examine the needs and demands for e-mental health interventions among individuals with overweight and obesity.

METHODS

A cross-sectional study was conducted from 2020 to 2021 in Germany. A total of 643 participants were recruited through specialized social media platforms and the Alfried-Krupp hospital in Essen, Germany. Sociodemographic and medical data were analysed, as well as data on depressive symptoms and on the needs and demands for e-mental health interventions.

RESULTS

Contact with and recommendation by experts appear to be key aspects in the acceptance and use of e-mental health interventions. In summary, most participants preferred a 20-30-min weekly session via smartphone over a 4-month period. The highest preference in terms of features included practicing coping skills and being provided with information; in regard to desired topics, nutrition consultation, quality of life, and adapting to new life situations were considered most important.

DISCUSSION

e-Mental health interventions can be highly beneficial for individuals, especially when developed through a user-centred design approach. The results of the study indicate which content and design are preferred and, thereby, provide valuable information for consideration when developing a tailored e-mental health intervention.

Effectiveness of mobile health interventions targeting parents to prevent and treat childhood Obesity: Systematic review

Childhood obesity is a high prevalence condition that causes a high burden of disease in adulthood. Mobile phone app are increasingly used to prevent it. We summarized the evidence on the effectiveness of mobile apps for devices used by parents to prevent and treat childhood and adolescent obesity. An update of a systematic review of the literature (De Lepeleere et al., 2017) was carried out. PubMed, Embase, Cochrane, CINAHL, PsycINFO, Scopus, and ERIC were searched up to 2020. The included studies should target children 1-18 years, compare an app aimed at preventing or treating overweight and obesity, as stand-alone intervention or as part of a complex program, installed on parents' mobile devices, to no intervention or an intervention without the app. Outcomes related to weight status, diet, and physical activity (PA) behaviors were considered. Nineteen studies (14 RCTs and 5 non-randomized trials) were included. The app was mainly used to record food consumption and PA, to set goals, to view progress, and send health promotion messages. One study reported a significant decrease and one a suggestive decrease in anthropometric measures in obese and overweight children, while other studies observed no effect. One study reported a significant increase in PA. Six interventions proved to be effective in changing dietary behaviors. Interventions targeting overweight and/or obese children had the most positive results. All studies reported high acceptability and feasibility of interventions. The differences between interventions and the small sample size of the studies did not allow this review to reach conclusion on effectiveness.

Efficacy of the Aim2Be intervention in changing lifestyle behaviours among adolescents with overweight and obesity: A Randomized Controlled Trial (Preprint)

BACKGROUND

Aim2Be is a gamified lifestyle app designed to promote lifestyle behavior changes among Canadian adolescents and their families.

OBJECTIVE

The primary aim was to test the efficacy of the Aim2Be app with support from a live coach to reduce weight outcomes (BMI Z score [zBMI]) and improve lifestyle behaviors among adolescents with overweight and obesity and their parents versus a waitlist control group over 3 months. The secondary aim was to compare health trajectories among waitlist control participants over 6 months (before and after receiving access to the app), assess whether support from a live coach enhanced intervention impact, and evaluate whether the app use influenced changes among intervention participants.

METHODS

A 2-arm parallel randomized controlled trial was conducted from November 2018 to June 2020. Adolescents aged 10 to 17 years with overweight or obesity and their parents were randomized into an intervention group (Aim2Be with a live coach for 6 months) or a waitlist control group (Aim2Be with no live coach; accessed after 3 months). Adolescents' assessments at baseline and at 3 and 6 months included measured height and weight, 24-hour dietary recalls, and daily step counts measured with a Fitbit. Data on self-reported physical activity, screen time, fruit and vegetable intake, and sugary beverage intake of adolescents and parents were also collected.

RESULTS

A total of 214 parent-child participants were randomized. In our primary analyses, there were no significant differences in zBMI or any of the health behaviors between the intervention and control groups at 3 months. In our secondary analyses, among waitlist control participants, zBMI (P=.02), discretionary calories (P=.03), and physical activity outside of school (P=.001) declined, whereas daily screen time increased (P<.001) after receiving access to the app compared with before receiving app access. Adolescents randomized to Aim2Be with live coaching reported more time being active outside of school compared with adolescents who used Aim2Be with no coaching over 3 months (P=.001). App use did not modify any changes in outcomes among adolescents in the intervention group.

CONCLUSIONS

The Aim2Be intervention did not improve zBMI and lifestyle behaviors in adolescents with overweight and obesity compared with the waitlist control group over 3 months. Future studies should explore the potential mediators of changes in zBMI and lifestyle behaviors as well as predictors of engagement.

Validity and Feasibility of the Monitoring and Modeling Family Eating Dynamics System to Automatically Detect In-field Family Eating Behavior: Observational Study

Background

The field of dietary assessment has a long history, marked by both controversies and advances. Emerging technologies may be a potential solution to address the limitations of self-report dietary assessment methods. The Monitoring and Modeling Family Eating Dynamics (M2FED) study uses wrist-worn smartwatches to automatically detect real-time eating activity in the field. The ecological momentary assessment (EMA) methodology was also used to confirm whether eating occurred (ie, ground truth) and to measure other contextual information, including positive and negative affect, hunger, satiety, mindful eating, and social context.

Objective

This study aims to report on participant compliance (feasibility) to the 2 distinct EMA protocols of the M2FED study (hourly time-triggered and eating event–triggered assessments) and on the performance (validity) of the smartwatch algorithm in automatically detecting eating events in a family-based study.

Methods

In all, 20 families (58 participants) participated in the 2-week, observational, M2FED study. All participants wore a smartwatch on their dominant hand and responded to time-triggered and eating event–triggered mobile questionnaires via EMA while at home. Compliance to EMA was calculated overall, for hourly time-triggered mobile questionnaires, and for eating event–triggered mobile questionnaires. The predictors of compliance were determined using a logistic regression model. The number of true and false positive eating events was calculated, as well as the precision of the smartwatch algorithm. The Mann-Whitney U test, Kruskal-Wallis test, and Spearman rank correlation were used to determine whether there were differences in the detection of eating events by participant age, gender, family role, and height.

Results

The overall compliance rate across the 20 deployments was 89.26% (3723/4171) for all EMAs, 89.7% (3328/3710) for time-triggered EMAs, and 85.7% (395/461) for eating event–triggered EMAs. Time of day (afternoon odds ratio [OR] 0.60, 95% CI 0.42-0.85; evening OR 0.53, 95% CI 0.38-0.74) and whether other family members had also answered an EMA (OR 2.07, 95% CI 1.66-2.58) were significant predictors of compliance to time-triggered EMAs. Weekend status (OR 2.40, 95% CI 1.25-4.91) and deployment day (OR 0.92, 95% CI 0.86-0.97) were significant predictors of compliance to eating event–triggered EMAs. Participants confirmed that 76.5% (302/395) of the detected events were true eating events (ie, true positives), and the precision was 0.77. The proportion of correctly detected eating events did not significantly differ by participant age, gender, family role, or height (P>.05).

Conclusions

This study demonstrates that EMA is a feasible tool to collect ground-truth eating activity and thus evaluate the performance of wearable sensors in the field. The combination of a wrist-worn smartwatch to automatically detect eating and a mobile device to capture ground-truth eating activity offers key advantages for the user and makes mobile health technologies more accessible to nonengineering behavioral researchers.

The effectiveness of e-health interventions for the treatment of overweight or obesity in children and adolescents: A systematic review and meta-analysis

The aim of this systematic review and meta-analysis was to examine the effectiveness of e-health interventions for the treatment of children and adolescents with overweight or obesity. Databases were searched up to November 2020. Studies were randomized controlled trials where interventions were delivered via e-health (e.g., computers, tablets, and smartphones, but not phone calls). Studies should target the treatment of overweight or obesity in children or their agent of changes and report body mass index (BMI) or BMI z-score. A meta-analysis using a random-effects model was conducted. Nineteen studies met the inclusion criteria, and 60% were of high quality. The narrative review revealed variation in behavior change strategies and modes of delivery. The pooled mean reduction in BMI or BMI z-score showed evidence for a nonzero effect (standardized mean difference = -0.31, 95% confidence interval -0.49 to -0.13), with moderately high heterogeneity between studies (I²  = 74%, p < 0.001). Subgroup analysis revealed high heterogeneity in studies with a high or unclear risk of bias. E-health interventions can be effective in treating children and adolescents with overweight and obesity and should be considered by practitioners and policymakers. However, an understanding of the most effective and acceptable intervention components, long-term benefits, and sustainability should be further studied.

Prevention of Pediatric Overweight and Obesity: Position of the Academy of Nutrition and Dietetics Based on an Umbrella Review of Systematic Reviews

This Academy of Nutrition and Dietetics Position Paper reports current evidence on pediatric overweight and obesity prevention interventions and discusses implications for registered dietitian nutritionists (RDNs). An overview of current systematic reviews provided evidence-based results from a range of nutrition interventions according to developmental age group (ages 2 to 5, 6 to 12, and 13 to 17 years). Twenty-one current systematic reviews of nutrition interventions demonstrated a beneficial effect of nutrition and physical activity interventions on body mass index measures and no adverse events were identified. RDNs impart nutrition expertise in a wide range of settings to provide comprehensive care for children and adolescents as their nutrition and developmental needs change over time. This Position Paper outlines the current roles of, and proposed directions for, RDNs engaged in pediatric overweight and obesity prevention. Prevention of pediatric overweight and obesity requires comprehensive strategies ranging from policy-level to individual-level interventions in settings that will have the most beneficial impact for children according to their developmental stage. This Position Paper advocates for increased availability of nutrition and food access programs and interventions to reduce risk of pediatric obesity and associated adverse health outcomes both now and for future generations.

Effectiveness of a Multifaceted Intervention for Prevention of Obesity in Primary School Children in China: A Cluster Randomized Clinical Trial

IMPORTANCE

A rapid nutritional transition has caused greater childhood obesity prevalence in many countries, but the repertoire of effective preventive interventions remains limited.

OBJECTIVE

To determine the effectiveness of a novel multifaceted intervention for obesity prevention in primary school children.

DESIGN, SETTING, AND PARTICIPANTS

A cluster randomized clinical trial was conducted during a single school year (from September 11, 2018, to June 30, 2019) across 3 socioeconomically distinct regions in China according to a prespecified trial protocol. Twenty-four schools were randomly allocated (1:1) to the intervention or the control group, with 1392 eligible children aged 8 to 10 years participating. Data from the intent-to-treat population were analyzed from October 1 to December 31, 2019.

INTERVENTIONS

A multifaceted intervention targeted both children (promoting healthy diet and physical activity) and their environment (engaging schools and families to support children's behavioral changes). The intervention was novel in its strengthening of family involvement with the assistance of a smartphone app. The control schools engaged in their usual practices.

MAIN OUTCOMES AND MEASURES

The primary outcome was the change in body mass index (BMI; calculated as weight in kilograms divided by height in square meters) from baseline to the end of the trial. Secondary outcomes included changes in adiposity outcomes (eg, BMI z score, prevalence of obesity), blood pressure, physical activity and dietary behaviors, obesity-related knowledge, and physical fitness. Generalized linear mixed models were used in the analyses.

RESULTS

Among the 1392 participants (mean [SD] age, 9.6 [0.4] years; 717 boys [51.5%]; mean [SD] BMI, 18.6 [3.7]), 1362 (97.8%) with follow-up data were included in the analyses. From baseline to the end of the trial, the mean BMI decreased in the intervention group, whereas it increased in the control group; the mean between-group difference in BMI change was -0.46 (95% CI, -0.67 to -0.25; P < .001), which showed no evidence of difference across different regions, sexes, maternal education levels, and primary caregivers (parents vs nonparents). The prevalence of obesity decreased by 27.0% of the baseline figure (a relative decrease) in the intervention group, compared with 5.6% in the control group. The intervention also improved other adiposity outcomes, dietary, sedentary, and physical activity behaviors, and obesity-related knowledge, but it did not change moderate- to vigorous-intensity physical activity, physical fitness, or blood pressure. No adverse events were observed during the intervention.

CONCLUSIONS AND RELEVANCE

The multifaceted intervention effectively reduced the mean BMI and obesity prevalence in primary school children across socioeconomically distinct regions in China, suggesting its potential for national scaling.

Effectiveness of digital primary prevention interventions targeting physical activity, motor skills and nutrition in children aged 3-10 years in the setting of day care and primary school: protocol for a systematic review

INTRODUCTION

Available evidence points to an association of increased screen time and the availability of digital tools during childhood with negative health outcomes in later life. For many years, public discourse focused on restricting access and use of digital technologies below certain ages. However, little is known about the specific benefit of a responsible use of digital primary prevention in the setting of (early) childhood education. The objective of this evidence synthesis is to investigate the effectiveness of digital primary prevention interventions targeting physical activity, motor skills and/or nutrition in children aged 3-10 years in day-care facilities and (pre-) schools.

METHODS AND ANALYSIS

We present the rationale and methodological steps of a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses procedures. Automated searches will be conducted by applying a pretested search strategy to the databases MEDLINE/PubMed, EMBASE and PsycInfo to identify relevant interventional (randomised controlled trials, controlled trials, crossover trials and pilot and feasibility) and observational (case-control, cohort) studies in English or German, with no date restrictions. The overall search will be complemented by backward, forward and additional hand searches. Two researchers will independently screen titles/abstracts and assess full texts by applying predefined eligibility criteria. Data extraction will be conducted by using a pretested data extraction sheet. The assessment of methodological quality will be performed independently by two review authors using the Critical Appraisals Skills Programme relevant to the study design applied in the given study. Additionally, qualitative content analysis will be conducted to analyse priorities for future research extracted from the discussion sections and conclusions of included studies.

Translating Family-Based Behavioral Treatment for Childhood Obesity into a User-Friendly Digital Package for Delivery to Low-Income Families through Primary Care Partnerships: The MO-CORD Study

Background: Significant gaps exist in access to evidence-based pediatric weight management interventions, especially for low-income families. As a part of the Centers for Disease Control and Prevention's Childhood Obesity Research Demonstration project 3.0 (CORD), the Missouri CORD (MO-CORD) team aims to increase access to and dissemination of an efficacious pediatric obesity treatment, family-based behavioral treatment (FBT), among low-income families. This article describes the MO-CORD team's approach to translating FBT into a digital package for delivery to low-income families through primary care practices. Methods: Using digital technology, the primary care setting, and existing reimbursement mechanisms, the MO-CORD team is developing a scalable user-centered design informed treatment package of FBT. This package will be implemented in primary care clinics and delivered to children (5-12 years) with obesity from low-income households in rural and urban communities. The digital platform includes three main components: (1) provider and interventionist training, (2) interventionist-facing materials, and (3) family-facing treatment materials. User-centered design techniques and continuous iterative stakeholder feedback are utilized to emphasize tailoring to a low-income population, along with scalability and sustainability of the digital package. Conclusions: The MO-CORD project addresses the critical need to increase access to obesity treatment for children from low-income households and establishes a platform for future large-scale (i.e., nation-wide) dissemination of evidence-based pediatric weight-management interventions. This study determines whether the digital FBT package can be implemented within real-world settings to create a system by which children with obesity and their families can be effectively treated in primary care settings.
