BackgroundAccess to physical activity among youth with spina bifida (SB) is much lower than it is for children without disability. Enjoyable home-based exercise programs are greatly needed. ObjectiveOur objective is to examine the feasibility of a virtual reality (VR) active video gaming system (ie, bundle of consumer-available equipment) to meet US physical activity guidelines in two youth with SB. MethodsTwo youth with SB—a 12-year-old female and a 13-year-old male; both full-time wheelchair users—participated in a brief, 4-week exercise program using a popular VR head-mounted display: Oculus Quest (Facebook Technologies). The system included a Polar H10 (Polar Canada) Bluetooth heart rate monitor, a no-cost mobile phone app (VR Health Exercise Tracker [Virtual Reality Institute of Health and Exercise]), and 13 games. The intervention protocol was conducted entirely in the homes of the participants due to the coronavirus disease 2019 (COVID-19) pandemic. The VR system was shipped to participants and they were instructed to do their best to complete 60 minutes of moderate-intensity VR exercise per day. Exercise duration, intensity, and calories expended were objectively monitored and recorded during exercise using the heart rate monitor and a mobile app. Fatigue and depression were measured via self-report questionnaires at pre- and postintervention. Participants underwent a semistructured interview with research staff at postintervention. ResultsAcross the intervention period, the total average minutes of all exercise performed each week for participants 1 and 2 were 281 (SD 93) and 262 (SD 55) minutes, respectively. The total average minutes of moderate-intensity exercise performed per week for participants 1 and 2 were 184 (SD 103) (184/281, 65.4%) and 215 (SD 90) (215/262, 82.1%) minutes, respectively. One participant had a reduction in their depression score, using the Quality of Life in Neurological Disorders (Neuro-QoL) test, from baseline to postintervention, but no other changes were observed for fatigue and depression scores. Participants reported that the amount of exercise they completed was far higher than what was objectively recorded, due to usability issues with the chest-worn heart rate monitor. Participants noted that they were motivated to exercise due to the enjoyment of the games and VR headset as well as support from a caregiver. ConclusionsThis study demonstrated that two youth with SB who used wheelchairs could use a VR system to independently and safely achieve exercise guidelines at home. Study findings identified a promising protocol for promoting exercise in this population and this warrants further examination in future studies with larger samples.

Objective Obesity is associated with executive function (EF) deficits across the lifespan. Higher body mass index (BMI), obesity severity, and poorer adherence and weight outcomes in obesity treatment have all been associated with EF deficits. Adult literature has begun to emphasize neuroinflammation in obesity as a possible pathway to later cognitive impairment in EF. However, pediatric obesity literature has yet to establish associations between peripheral inflammation and EF. Thus, the present study examined associations and variability in inflammation, EF, and adiposity in children with or at risk for obesity. Additionally, inflammation was examined as a mediator of the relationship between adiposity and EF. Methods Children (N  = 39) aged 8–12 years with BMI ≥ 50th percentile were recruited. The NIH Toolbox Cognitive Battery was used to assess performance-based EF. Peripheral inflammation was assessed in fasted sera. Dual-energy X-ray absorptiometry scans were conducted to assess body composition. Linear regression and Hayes' PROCESS Model 4 (Hayes, 2017) were used to evaluate associations between adiposity and inflammation, inflammation and EF, and whether adiposity effects EF through its effect on inflammation. Results Positive associations were identified between adiposity and inflammation, and negative to null associations were identified between inflammation and EF. Medium indirect effects of adiposity on EF through inflammation were detected. Conclusion Pilot evidence suggests greater adiposity is linked with greater inflammation, which in turn is associated with less EF in some domains. Directionality and causality cannot yet be established, but with replication, findings may inform efforts to target EF in pediatric obesity. [ABSTRACT FROM AUTHOR]

Background: Adolescents with cerebral palsy (CP) who have mobility limitations have almost no access to inexpensive and enjoyable home-based programs that can be disseminated on a large scale to help them independently manage their health through participation in leisure-time physical activity (LTPA). Objective: The primary aim of this study was to determine the preliminary efficacy of the early adoption phase of an adult Movement-to-Music (M2M) program with behavioral telecoaching for increasing LTPA and activity participation compared with a waitlist control group in adolescents with CP. The secondary aim was to explore the effects of the program on perceived levels of pain and fatigue. The tertiary aim was to qualitatively evaluate the factors that influenced adherence and develop a theory that would inform the development of a more targeted M2M telehealth program for this group. Methods: This randomized controlled trial piloted a 4-week M2M program with weekly behavioral telecoaching among 58 adolescents with CP who walked or used wheelchairs. The participants were randomized into one of 2 groups: M2M or control, which maintained their daily activities. M2M included videos that participants were asked to complete 3 times each week at home (asynchronous training). Adherence to video minutes was objectively measured using cloud-based analytics. Changes in activity and LTPA participation were measured before and after the intervention using the Children's Assessment of Participation and Enjoyment total domain scores and active physical recreation domain scores, respectively. Perceived pain and fatigue were measured using the National Institutes of Health Neuro-QoL short forms. The changes in scores were compared between the groups using analysis of covariance. A grounded theory approach was used to analyze one-on-one interviews, coaching notes, and feedback surveys. Results: A total of 58 people were enrolled, of which 49 (84%) completed the primary outcome follow-up assessment. The mean adherence to the prescribed exercise video minutes across all 4 weeks was 68%, starting from 90% in week 1 and gradually declining to 43% in week 4. Mean adherence to coaching calls was 91%. Analysis of covariance revealed a statistically significant difference between the pre- to postchange scores for Children's Assessment of Participation and Enjoyment Active Physical Recreation-Intensity domain scores in favor of the intervention group (F1,47=8.76; P=.005; effect size=0.17, also known as volume of LTPA). The qualitative findings highlighted 5 critical factors that influenced participants' adherence to the program: caregiver support, video elements, suitable exercises, music, and behavioral coaching. Conclusions: This project determined that adolescents with CP responded well to an M2M telehealth program that could enhance their LTPA levels. This paper describes a theory in which adherence to a telehealth LTPA program can be optimized through functional and age-specific modifications for adolescents with CP. [ABSTRACT FROM AUTHOR]

Objective: To examine the association between caregiver proxy report of executive function (EF) and dysregulated eating behavior in children with obesity.Methods: Participants were 195 youth with obesity aged 8-17 years, and their legal guardians. Youth height, weight, demographics, depressive symptoms, eating behaviors, and EF were assessed cross-sectionally during a medical visit. Analyses of covariance, adjusted for child age, gender, race/ethnicity, standardized BMI, depressive symptoms, and family income were used to examine differences in youth EF across caregiver and youth self-report of eating behaviors.Results: Youth EF differed significantly by caregiver report of eating behavior but not youth self-report. Post hoc analyses showed that youth with overeating or binge eating had poorer EF than youth without these eating behaviors.Conclusions: Executive dysfunction, as reported by caregivers, in youth with obesity may be associated with dysregulated eating behaviors predictive of poor long-term psychosocial and weight outcomes. Further consideration of EF-specific targets for assessment and intervention in youth with obesity may be warranted. [ABSTRACT FROM AUTHOR]

Objective: To examine the associations of peer victimization with internalizing symptoms, externalizing symptoms, social competence, and academic performance in a clinical sample of adolescents with severe obesity, and whether self-worth and social support affect these associations.Methods: Multisite cross-sectional data from 139 adolescents before weight loss surgery ( M age = 16.9; 79.9% female, 66.2% White; M Body Mass Index [BMI] = 51.5 kg/m 2 ) and 83 nonsurgical comparisons ( M age = 16.1; 81.9% female, 54.2% White; M BMI = 46.9 kg/m 2 ) were collected using self-reports with standardized measures.Results: As a group, participants did not report high levels of victimization. Self-worth mediated the effects of victimization on a majority of measures of adjustment, and further analyses provided evidence of the buffering effect of social support for some mediational models.Conclusions: Self-worth and social support are important targets for prevention and intervention for both victimization and poor adjustment in adolescent severe obesity.

Objective: Examine relations between depressive symptoms, ethnic identity, and health-related quality of life (HRQOL) in overweight or obese (OV/OB) children.Methods: A total of 166 OV/OB 8- to 17-year-olds (M = 12.94 years; 86.7% obese; 50.6% racial/ethnic minority) attending an outpatient pediatric obesity medical clinic participated. Children completed the Children's Depression Inventory-Short Form, Multigroup Ethnic Identity Measure (MEIM), and Pediatric Quality of Life Inventory.Results: Increased depressive symptoms significantly predicted reduced total, physical, and psychosocial HRQOL. For minority OV/OB youth only, MEIM Affirmation/Belonging moderated depressive symptoms and total HRQOL (effect = -2.59, t = -2.24, p = .027; R(2) overall model = 0.315) and depressive symptoms and psychosocial HRQOL (effect = -3.01, t = -2.47, p = .015; R(2) overall model = 0.331).Conclusions: Depressive symptoms are negatively associated with HRQOL. In minority OV/OB youth, high ethnic identity may be protective when depressive symptoms are minimal. Ethnic identity and other cultural factors are important to consider in psychosocial treatments for pediatric obesity. [ABSTRACT FROM AUTHOR]
