Treating rural pediatric obesity through telemedicine: baseline data from a randomized controlled trial

'eatNplay' - a rurally-tailored, family-based, telehealth intervention for childhood obesity: Protocol for a mixed-methods randomized newsletter controlled pilot study

BACKGROUND

Childhood obesity disproportionately affects rural communities where access to pediatric weight control services is limited. Telehealth may facilitate access to these services.

OBJECTIVE

This paper describes the rationale, curriculum, and methodology for conducting a randomized controlled pilot trial of a rural, family-based, telehealth intervention that aims to improve weight-related behaviors among children, compared to monthly newsletters.

METHODS

A mixed-methods randomized design will randomly assign 44 rural families with one or more children aged 5 to 11 years identified as overweight or obese to an intervention or newsletter control group. The intervention group will attend 'eatNplay' group videoconferencing telehealth sessions, conducted weekly by a registered nurse and a motivational interviewing expert, to discuss diet, exercise, sleep, and peer group influences. The control group will receive newsletters covering these topics. Outcome measures at baseline, 12, and 26 weeks will assess 1) participant engagement and satisfaction with 'eatNplay'; 2) child's BMI, dietary behavior, physical activity, and sleep behavior; and 3) parent/guardians' self-reported beliefs, behaviors, attitudes, perceived stress, and perceived quality of life. Analyses will employ 1) thematic analysis of semi-structured parent/guardian interviews after follow-up to help refine the intervention (e.g., curriculum), and 2) linear mixed models to compare outcomes between groups pre- and post-intervention and reduce bias from unobserved variables. Results of this pilot study could refine methodology for conducting telehealth studies, acceptability of healthcare provider-involved recruitment, interdisciplinary team approach, and addressing childhood obesity in rural communities through telehealth.

The Application of Telemedicine to Pediatric Obesity: Lessons from the Past Decade

Background: Telemedicine has been utilized to deliver pediatric weight management care in both rural and urban communities. This method of health care delivery may provide a solution to the many logistical obstacles to pediatric obesity management, including time, finances, and distance to programs. Objectives: This review examines all studies in the past decade that employed telehealth communication directly between families and obesity specialists to treat pediatric obesity. To assess the practical use of such programs, studies that surveyed family satisfaction with this method of health care are also included. Methods: A comprehensive electronic database search was conducted in PubMed/MEDLINE, Scopus, CINAHL, and Cochrane Library databases. Results: All studies demonstrated noninferiority in clinical efficacy as measured by weight status improvement in participants of either the telehealth cohort or the in-person cohort. Attrition rates were also not statistically significant between groups. Patient satisfaction with telemedicine delivery was high across studies. Lack of statistical significance in outcomes of these studies can be attributed to infrequent visits, limited duration of programs, and study size. Conclusions: Future research is needed to evaluate the effect on health outcomes as well as compliance when direct to consumer telemedicine visits are integrated in pediatric weight management clinics with more frequency and for longer duration. This method of telemedicine would allow for increased contact with patients and families in between face-to-face encounters. Telehealth provides the potential to create more robust, accessible, and effective pediatric weight management programs.

Potential solutions for pediatric weight loss programs in the treatment of obesity in rural communities

Pediatric obesity remains disproportionately more prevalent in rural communities; however, multidisciplinary, pediatric weight loss programs, which are often located in tertiary-care centers, may not be accessible to rural families. Limited models to specifically address pediatric obesity in rural communities exist. Therefore, innovative solutions are required for expanded treatment of pediatric obesity in rural communities. This article discusses potential solutions for multidisciplinary, tertiary-care pediatric weight loss programs to improve access and treatment of pediatric obesity in rural communities. A selected review of the literature suggests that strategies to overcome barriers to treatment in rural communities include telephone calls and telemedicine conferencing by obesity specialists from academic centers (obesity medicine specialists, endocrinologists, dietitians, and psychotherapists) as well as training local primary care providers in rural communities to screen, diagnose, and treat patients with obesity. Multidisciplinary, tertiary-care pediatric weight loss programs have a profound opportunity to impact the treatment of pediatric obesity in rural communities by training practicing rural primary care providers as well as strengthening their commitment to educate future generations of clinicians on the treatment of pediatric obesity through medical training including physician assistant, nurse practitioner, and pediatric and family medicine resident education and skill building. This article identifies potential mechanisms for expansive treatment of pediatric obesity in rural communities by multidisciplinary, tertiary-care weight loss programs and highlights areas of specific focus needed for future investigation.

iAmHealthy: Rationale, design and application of a family-based mHealth pediatric obesity intervention for rural children

Children in rural areas are disproportionately affected by pediatric obesity. Poor access to healthcare providers, lack of nutrition education, lower socioeconomic status, and fewer opportunities to be physically active are all unique barriers that contribute to this growing health concern. There are very few pediatric obesity interventions that have been developed that target this unique population. iAmHealthy is a family-based behavioral, nutrition and physical activity intervention developed with input from rural children and families that capitalizes on the innovative use of mobile health applications (mHealth). iAmHealthy is a 25-contact hour multicomponent intervention delivered over an 8-month period targeting 2nd-4th grade school children and their families. This paper describes the rationale, design, participant/school enrollment, and planned implementation of a randomized controlled trial of the iAmHealthy intervention in comparison to a monthly newsletter delivered through rural elementary schools. Child Body Mass Index z-score (BMIz) is the primary outcome, along with child 24-hour dietary recall, and child accelerometer-determined physical activity and sedentary behavior as secondary outcomes. The study will include 18 schools (with 8 children each) resulting in a final planned sample size of 144 children. This project also has a strong focus on dissemination and implementation science, and thus includes many measures related to the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, and Maintenance). Data collection is completed at baseline, end of intervention (8 months), and follow-up (20 months). This study is the first randomized controlled trial to deliver a rurally tailored, empirically supported, family-based behavioral intervention for pediatric obesity solely over mHealth. Registered with ClinicalTrials.gov NCT ID 03304249.

Breaking barriers: Adjunctive use of the Ontario Telemedicine Network (OTN) to reach adolescents with obesity living in remote locations

INTRODUCTION

Implementation of telemedicine has been shown to improve health outcomes, such as body mass index (BMI). However, it is unclear whether telemedicine is useful alongside traditional weight-management programmes for adolescents with complex obesity. The objective was to evaluate implementation of the Ontario Telemedicine Network (OTN), a videoconferencing programme, as an adjunctive tool to face-to-face counselling within the setting of an established interdisciplinary obesity treatment programme.

METHODS

Our observational cohort included two groups of adolescents enrolled in a clinical obesity-management programme over a two year period. Adolescents (n = 50) in group 1 attended both in-person and virtual visits (OTN group), and adolescents (n = 50) in group 2 received only in-person visits (comparison group). Within the OTN group, satisfaction survey responses were compared between patients and healthcare professionals. Change in BMI per month, paediatric quality of life scores, session attendance and demographic variables were compared between groups.

RESULTS

OTN subjects averaged 4.9 telehealth visits per adolescent over the two year programme. Both OTN and comparison groups had similar changes in BMI (p = 0.757), with increases over time (p = 0.042). Paediatric quality of life scores in both groups improved over time compared to baseline (p < 0.001), with higher scores for children compared to parental-reported child scores (p = 0.008). Both adolescents and healthcare professionals using the OTN were similarly satisfied with their experience.

CONCLUSION

Adjunctive use of the OTN within the setting of a weight-management programme is feasible, well accepted by families and healthcare providers, and led to similar outcomes compared to usual care.

Diet, physical activity and behavioural interventions for the treatment of overweight or obese children from the age of 6 to 11 years

BACKGROUND

Child and adolescent overweight and obesity has increased globally, and can be associated with significant short- and long-term health consequences. This is an update of a Cochrane review published first in 2003, and updated previously in 2009. However, the update has now been split into six reviews addressing different childhood obesity treatments at different ages.

OBJECTIVES

To assess the effects of diet, physical activity and behavioural interventions (behaviour-changing interventions) for the treatment of overweight or obese children aged 6 to 11 years.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, LILACS as well as trial registers ClinicalTrials.gov and ICTRP Search Portal. We checked references of studies and systematic reviews. We did not apply any language restrictions. The date of the last search was July 2016 for all databases.

SELECTION CRITERIA

We selected randomised controlled trials (RCTs) of diet, physical activity, and behavioural interventions (behaviour-changing interventions) for treating overweight or obese children aged 6 to 11 years, with a minimum of six months' follow-up. We excluded interventions that specifically dealt with the treatment of eating disorders or type 2 diabetes, or included participants with a secondary or syndromic cause of obesity.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened references, extracted data, assessed risk of bias, and evaluated the quality of the evidence using the GRADE instrument. We contacted study authors for additional information. We carried out meta-analyses according to the statistical guidelines in the Cochrane Handbook for Systematic Reviews of Interventions.

MAIN RESULTS

We included 70 RCTs with a total of 8461 participants randomised to either the intervention or control groups. The number of participants per trial ranged from 16 to 686. Fifty-five trials compared a behaviour-changing intervention with no treatment/usual care control and 15 evaluated the effectiveness of adding an additional component to a behaviour-changing intervention. Sixty-four trials were parallel RCTs, and four were cluster RCTs. Sixty-four trials were multicomponent, two were diet only and four were physical activity only interventions. Ten trials had more than two arms. The overall quality of the evidence was low or very low and 62 trials had a high risk of bias for at least one criterion. Total duration of trials ranged from six months to three years. The median age of participants was 10 years old and the median BMI z score was 2.2.Primary analyses demonstrated that behaviour-changing interventions compared to no treatment/usual care control at longest follow-up reduced BMI, BMI z score and weight. Mean difference (MD) in BMI was -0.53 kg/m2 (95% confidence interval (CI) -0.82 to -0.24); P < 0.00001; 24 trials; 2785 participants; low-quality evidence. MD in BMI z score was -0.06 units (95% CI -0.10 to -0.02); P = 0.001; 37 trials; 4019 participants; low-quality evidence and MD in weight was -1.45 kg (95% CI -1.88 to -1.02); P < 0.00001; 17 trials; 1774 participants; low-quality evidence.Thirty-one trials reported on serious adverse events, with 29 trials reporting zero occurrences RR 0.57 (95% CI 0.17 to 1.93); P = 0.37; 4/2105 participants in the behaviour-changing intervention groups compared with 7/1991 participants in the comparator groups). Few trials reported health-related quality of life or behaviour change outcomes, and none of the analyses demonstrated a substantial difference in these outcomes between intervention and control. In two trials reporting on minutes per day of TV viewing, a small reduction of 6.6 minutes per day (95% CI -12.88 to -0.31), P = 0.04; 2 trials; 55 participants) was found in favour of the intervention. No trials reported on all-cause mortality, morbidity or socioeconomic effects, and few trials reported on participant views; none of which could be meta-analysed.As the meta-analyses revealed substantial heterogeneity, we conducted subgroup analyses to examine the impact of type of comparator, type of intervention, risk of attrition bias, setting, duration of post-intervention follow-up period, parental involvement and baseline BMI z score. No subgroup effects were shown for any of the subgroups on any of the outcomes. Some data indicated that a reduction in BMI immediately post-intervention was no longer evident at follow-up at less than six months, which has to be investigated in further trials.

AUTHORS' CONCLUSIONS

Multi-component behaviour-changing interventions that incorporate diet, physical activity and behaviour change may be beneficial in achieving small, short-term reductions in BMI, BMI z score and weight in children aged 6 to 11 years. The evidence suggests a very low occurrence of adverse events. The quality of the evidence was low or very low. The heterogeneity observed across all outcomes was not explained by subgrouping. Further research is required of behaviour-changing interventions in lower income countries and in children from different ethnic groups; also on the impact of behaviour-changing interventions on health-related quality of life and comorbidities. The sustainability of reduction in BMI/BMI z score and weight is a key consideration and there is a need for longer-term follow-up and further research on the most appropriate forms of post-intervention maintenance in order to ensure intervention benefits are sustained over the longer term.

A Review of Primary Care-Based Childhood Obesity Prevention and Treatment Interventions

Effective obesity prevention and treatment interventions targeting children and their families are needed to help curb the obesity epidemic. Pediatric primary care is a promising setting for these interventions, and a growing number of studies are set in this context. This review aims to identify randomized controlled trials of pediatric primary care-based obesity interventions. A literature search of 3 databases retrieved 2947 publications, of which 2899 publications were excluded after abstract (n=2722) and full-text review (n=177). Forty-eight publications, representing 31 studies, were included in the review. Eight studies demonstrated a significant intervention effect on child weight outcomes (e.g., BMI z-score, weight-for-length percentile). Effective interventions were mainly treatment interventions, and tended to focus on multiple behaviors, contain weight management components, and include monitoring of weight-related behaviors (e.g., dietary intake, physical activity, or sedentary behaviors). Overall, results demonstrate modest support for the efficacy of obesity treatment interventions set in primary care.

Treating rural paediatric obesity through telemedicine vs. telephone: Outcomes from a cluster randomized controlled trial

OBJECTIVE

The objective of the current study was to examine the feasibility of telemedicine vs. telephone for the delivery of a multidisciplinary weekly family-based behavioural group intervention to treat paediatric obesity delivered to families living in rural areas using a randomized controlled trial methodology.

METHODS

103 rural children and their families were recruited. Feasibility measures included participant satisfaction, session attendance and retention. Treatment outcome measures included child Body Mass Index z-score (BMIz), parent BMI, 24-hour dietary recalls, accelerometer data, the child behavior checklist and the behavioral pediatrics feeding assessment scale.

RESULTS

Participants were highly satisfied with the intervention both via telemedicine and via telephone. Completion rates were much higher than for other paediatric obesity intervention programmes, and both methodologies were highly feasible. There were no differences in telemedicine and telephone groups on primary outcomes.

CONCLUSION

Both telemedicine and telephone intervention appear to be feasible and acceptable methods of delivering paediatric obesity treatment to rural children.

Weaning children off enteral nutrition by netcoaching versus onsite treatment: a comparative study

AIM

The Graz model of tube weaning has been internationally recognised as a successful and rapid tube weaning program. Beside the onsite treatment option, a telemedical counselling was specifically developed in 2009. This study aims to show outcomes of this newly invented treatment in a large sample of patients.

METHODS

Our retrospective open-label study compared success of onsite versus telemedical Graz-based weaning methods for patients with diverse clinical diagnoses with either nasogastric, gastric or jejunal tubes. Outcome variables were successful transition to oral feeds, partial transition to night tube feeds, and failure or interruption of intervention. Patients and physicians chose the intervention method.

RESULTS

Complete weaning was achieved in 153 of 169 (90.5%) children in the netcoaching group versus 170 of 209 (81.3%) of those opting for onsite treatment (no significant differences, P > 0.05). Higher partial weaning rates were observed in the onsite group (15.3% vs. 4.7%, P < 0.01, degrees of freedom = 3, χ(2) = 22.76). There were no significant differences regarding the outcomes 'weaning trial without success' (netcoaching: 0% vs. onsite: 2.9%, P > 0.05) and 'interruption of programme' (netcoaching: 4.7% vs. onsite: 0.5%, P > 0.05) between the two groups.

CONCLUSION

Despite limitations of study design, we have demonstrated similar efficacy of Graz-based less expensive netcoaching versus more expensive onsite intervention in a large referral population with chronic tube dependency with the majority transitioning to complete oral feeds.

Outcomes of a weight management clinic for children with special needs

OBJECTIVE

Rates of obesity are elevated among children with special needs (e.g., autism spectrum disorder, Down syndrome, or developmental disabilities). The objective of this study was to evaluate the effectiveness of a multidisciplinary tailored intervention to treat obesity among youth with special needs.

METHOD

Seventy-six children aged 2 to 19 years participated in a multidisciplinary weight management clinic adapted for children with special needs. A description of the patients presenting for specialized clinical services is provided, and the impact of the intervention on child body mass index (BMI) and food variety was examined for a subset (n = 30) of children. Descriptive statistics of the patient population at baseline were calculated and a series of t tests, correlations, and analysis of variance models examined change in BMI z-scores (BMIz) and diet variety. Factors related to treatment outcomes were also explored.

RESULTS

BMIz decreased significantly by the 6-month follow-up (M = 2.43 to M = 2.36, p < .01). There were significant increases in the variety of fruits, vegetables, and grains that children ate (t(16) = 3.18, p < .01; t(16) = 2.63, p = .02; t(16) = 2.37, p = .03, respectively).

CONCLUSION

A multidisciplinary clinic-based intervention was effective in reducing BMIz over a 6-month period and increasing the variety of foods that children were eating. These results have implications for providing tailored weight management interventions for youth with obesity and special needs.

Measurement of mealtime behaviors in rural overweight children: an exploratory factor analysis of the Behavioral Pediatrics Feeding Assessment Scale

OBJECTIVE

The current study presents results of an exploratory factor analysis (EFA) of the Behavioral Pediatric Feeding Assessment Scale (BPFAS) in a sample of rural children with overweight and obesity. Relationships between mealtime behavior and health outcomes are also explored.

METHODS

EFA was used to assess the fit of the BPFAS in a group of 160 treatment-seeking children (Mage = 9.11, SD = 1.77) living in rural Midwest communities. Correlations were also computed between factor scores and select health variables (child body mass index z-score and diet variables).

RESULTS

The EFA identified a 5-factor solution as the best fitting model (Tucker-Lewis Index = .96, root mean square error of approximation = .05), although several items (i.e., 7 of 25) did not load on any factor. 2 factors were correlated with health variables of interest.

CONCLUSION

Study results suggest that certain items on the BPFAS may not be appropriate for use with rural children with pediatric overweight or obesity. Implications for future research and practice are discussed.

Health information technology in screening and treatment of child obesity: a systematic review

BACKGROUND AND OBJECTIVES

Childhood obesity is a major problem in the United States, yet screening and treatment are often inaccessible or ineffective. Health information technology (IT) may improve the quality, efficiency, and reach of chronic disease management. The objective of this study was to review the effect of health IT (electronic health records [EHRs], telemedicine, text message or telephone support) on patient outcomes and care processes in pediatric obesity management.

METHODS

Medline, Embase, and the Cochrane Registry of Controlled Trials were searched from January 2006 to April 2012. Controlled trials, before-and-after studies, and cross-sectional studies were included if they used IT to deliver obesity screening or treatment to children aged 2 to 18 and reported impact on patient outcomes (BMI, dietary or physical activity behavior change) or care processes (BMI screening, comorbidity testing, diet, or physical activity counseling). Two independent reviewers extracted data and assessed trial quality.

RESULTS

Thirteen studies met inclusion criteria. EHR use was associated with increased BMI screening rates in 5 of 8 studies. Telemedicine counseling was associated with changes in BMI percentile similar to that of in-person counseling and improved treatment access in 2 studies. Text message or telephone support was associated with weight loss maintenance in 1 of 3 studies.

CONCLUSIONS

To date, health IT interventions have improved access to obesity treatment and rates of screening. However, the impact on weight loss and other health outcomes remains understudied and inconsistent. More interactive and time-intensive interventions may enhance health IT's clinical effectiveness in chronic disease management.

Treatment of pediatric obesity using a parent-only approach: a case example

OBJECTIVE

There is a great need for solution-oriented studies and descriptions of interventions for pediatric obesity in real-world settings. This report describes a group-based behavioral parent-only intervention to promote healthier lifestyle habits and reduce weight status in an obese 12-year-old female participant.

METHOD

The behavioral parent-only intervention program described was part of a randomized controlled trial that evaluated the impact of 2 behavioral interventions that addressed dietary intake, physical activity, and weight status in overweight and obese youth living in rural settings. Both the child and parent were targeted for behavior change. The intervention included 12 group sessions over 4 months. Behavioral strategies, including self-monitoring, goal setting, performance feedback, reinforcement, stimulus control, and instruction in behavioral parenting strategies were flexibly applied to meet the needs of the family. Assessments were completed at baseline, month-4 posttreatment, and month-10 follow-up.

RESULTS

The parent attended 10 of 12 treatment sessions. At follow-up the child had lost 17 pounds and grew 1.7 in. in height. The child also experienced improved quality of dietary intake and a drop in the number of self-reported unhealthy weight control behaviors. The parent experienced no notable decrease or increase in BMI.

CONCLUSIONS

The report describes the successful application of a behavioral intervention to address pediatric obesity that uses a parent-only approach. It is hoped that this presentation will facilitate discussion and help encourage further presentations of how the flexible application of evidenced-based interventions can be applied in real-world settings.

Treating rural pediatric obesity through telemedicine: outcomes from a small randomized controlled trial

OBJECTIVE

The objective of the current study was to examine the effectiveness of a multidisciplinary weekly family-based behavioral group delivered via telemedicine to rural areas, compared with a standard physician visit intervention.

METHODS

A randomized controlled trial was conducted with 58 rural children and their families comparing a family-based behavioral intervention delivered via telemedicine to a structured physician visit condition. Outcome measures included child body mass index z-score (BMIz), 24-hr dietary recalls, accelerometer data, Child Behavior Checklist, Behavioral Pediatrics Feeding Assessment Scale, and feasibility and fidelity.

RESULTS

Child BMIz outcomes were not statistically different between the 2 groups (F = 0.023, p = .881). Improvements in BMIz, nutrition, and physical activity were seen for both groups.

CONCLUSIONS

Both telemedicine and structured physician visit may be feasible and acceptable methods of delivering pediatric obesity treatment to rural children.
