RESUMEN
Youth with intellectual disabilities engage in low levels of physical activity (PA). An aim of this family-based weight-loss behavioral intervention (FBBI) trial was to increase and sustain PA in these youth. Accelerometry data were available from 21 individuals with intellectual disabilities, age 14-22 years. Each completed the 6-month FBBI, after which 10 completed a 6-month maintenance intervention (FBBI-M), and 11 received no further intervention (FBBI-C). Twenty participated in a further 6-month follow-up. Accelerometry data were analyzed using linear mixed models. During FBBI, mean (SE) moderate to vigorous PA increased by 4.1 (2.5) min/day and light PA by 24.2 (13.5) min/day. Mean (SE) difference in moderate to vigorous PA between participants in FBBI-M and FBBI-C at 18 months was 14.0 (5.1) min/day (p = .005); mean (SE) difference in light PA was 47.4 (27.4) min/day (p = .08). Increasing PA through behavioral intervention is possible in youth with intellectual disabilities.

There is considerably greater variation in metabolic rates between men than between women, in terms of basal, activity and total (daily) energy expenditure (EE). One possible explanation is that EE is associated with male sexual characteristics (which are known to vary more than other traits) such as musculature and athletic capacity. Such traits might be predicted to be most prominent during periods of adolescence and young adulthood, when sexual behaviour develops and peaks. We tested this hypothesis on a large dataset by comparing the amount of male variation and female variation in total EE, activity EE and basal EE, at different life stages, along with several morphological traits: height, fat free mass and fat mass. Total EE, and to some degree also activity EE, exhibit considerable greater male variation (GMV) in young adults, and then a decreasing GMV in progressively older individuals. Arguably, basal EE, and also morphometrics, do not exhibit this pattern. These findings suggest that single male sexual characteristics may not exhibit peak GMV in young adulthood, however total and perhaps also activity EE, associated with many morphological and physiological traits combined, do exhibit GMV most prominently during the reproductive life stages.

BACKGROUND: We examined differences in food selectivity by gender and parent race/ethnicity in children with intellectual disabilities. METHOD: A convenience sample of 56 children with intellectual disabilities was analysed. A modified Youth/Adolescent Food Frequency Questionnaire and a 3-day food record were used to measure child food refusal rate and food repertoire, respectively. RESULTS: Boys were about twice as likely to refuse total foods (rate ratio = 2.34, 95%CI = 1.34-4.09) and fruits (rate ratio = 2.03, 95%CI = 1.04-3.95) and 54% more likely to refuse vegetables (rate ratio = 1.54, 95%CI = 0.93-2.54). Children with Hispanic parents were twice as likely to refuse vegetables compared to children with non-Hispanic White parents (rate ratio = 2.00, 95%CI = 1.03-3.90). In analyses stratified by the presence or absence of co-occurring probable autism spectrum disorder, boys had greater food selectivity than girls. CONCLUSIONS: This study expands our understanding of food selectivity in children with intellectual disabilities.

BACKGROUND: Some studies suggest that children and adolescents with intellectual disability (ID) are at elevated risk of obesity. The objective was to determine the prevalence of and factors associated with overweight and obesity among students attending special education schools in Cantabria, Spain. METHODS: Cross-sectional design. A sample of n = 220 students with intellectual disability attending seven special education schools was selected using convenience sampling. Body mass index was classified into four categories according to the International Obesity Task Force (IOTF) criteria: underweight; normal weight; overweight; obesity. RESULTS: The prevalence of overweight/obesity was 40.9% (95% CI: 34.6-47.5). Obesity was more frequent among females (26.0%) than males (9.8%), with an OR = 3.23 (95% CI: 1.53-6.85). Participants with Down syndrome showed an increased risk of obesity compared to other conditions (p = .005). CONCLUSIONS: The prevalence of overweight/obesity among children, adolescents and young adults with intellectual disability was remarkably high, with females in general and students of both sexes with Down syndrome at particularly high risk.

OBJECTIVE: Longitudinal data on cardiometabolic effects of egg intake during adolescence are lacking. The current analyses aim to evaluate the impact of usual adolescent egg consumption on lipid levels, fasting glucose, and insulin resistance during late adolescence (age 17-20 years). METHODS: Data from 1392 girls, aged 9 to 10 at baseline and followed for 10 years, in the National Heart, Lung, and Blood Institute's National Growth and Health Study were used to examine the association between usual egg intake alone and in combination with other healthy lifestyle factors and late adolescent lipid levels, fasting glucose, and insulin resistance, measured as homeostasis model assessment of insulin resistance (HOMA-IR). Diet was assessed using 3-day food records during eight examination cycles. Girls were classified according to usual weekly egg intake, ages 9-17 years: <1 egg/wk (n = 361), 1 to <3 eggs/wk (n = 703), and ≥3 eggs/wk (n = 328). Analysis of covariance modeling was used to control for confounding by other behavioral and biological risk factors. RESULTS: Girls with low, moderate, and high egg intakes had adjusted low-density lipoprotein cholesterol levels of 99.7, 98.8, and 95.5 mg/dL, respectively (p = 0.0778). In combination with higher intakes of fiber, dairy, or fruits and vegetables, these beneficial effects were stronger and statistically significant. There was no evidence that ≥3 eggs/wk had an adverse effect on lipids, glucose, or HOMA-IR. More active girls who consumed ≥3 eggs/wk had the lowest levels of insulin resistance. CONCLUSION: These results suggest that eggs may be included as part of a healthy adolescent diet without adverse effects on glucose, lipid levels, or insulin resistance.

Children with developmental concerns are more likely to be referred to feeding clinics for food selectivity than typically developing (TD) children. However, there is limited research on food selectivity in children with intellectual disabilities (ID). Fifty-nine TD children and 56 children with ID ages 3-8 years participated in the Children's Mealtime Study to compare food selectivity, conceptualized as food refusal and narrow food repertoire, among TD children and children with ID. Parents completed a 119-item food frequency questionnaire. Food refusal rate was calculated as the number of foods the child refused of those offered. Food repertoire, comprising the number of unique foods eaten, was determined from a 3-day food record. Compared to TD children, among children with ID the food refusal rate was significantly higher (28.5% vs. 15.7%) and mean food repertoire significantly narrower (20.7 vs. 24.2 unique foods) (pâ¯<â¯0.01). Approximately 10% of children with ID and approximately 4% of TD children reported eating no fruit on any of the three days of food intake recording, and approximately 10% of children with ID compared to approximately 2% of TD children reported no vegetable intake on any of the three days. In further analyses, we examined the two measures of food selectivity among children with both ID and probable autism spectrum disorder (ASD) (by the Autism Spectrum Rating Scale) compared to children with ID only and to TD children. Food selectivity appeared to be primarily attributable to those children who also had a probable diagnosis of ASD. These findings support the need for screening for food selectivity of children with ID, particularly those who also have ASD. Children who exhibit food selectivity should be referred for further evaluation and intervention.

BACKGROUND: The input of youth with intellectual disabilities in health promotion and health disparities research is essential for understanding their needs and preferences. Regular physical activity (PA) is vital for health and well-being, but levels are low in youth generally, including those with intellectual disabilities. Understanding the perceptions of and barriers to PA as reported by youth with intellectual disabilities themselves is important for designing effective interventions. MATERIALS AND METHODS: We developed a structured interview that queried youth with intellectual disabilities and typically developing youth (ages 13-21 years) about their enjoyment, preferences and perceived barriers to PA. We describe the development of this interview and present its test-retest reliability on 15 youth with intellectual disabilities and 20 typically developing youth. RESULTS: Twenty-three of 33 questions were reliable in both groups. The results suggest that youth with intellectual disabilities can reliably report activities that they do or do not enjoy, as well as their beliefs and perceived benefits of PA. CONCLUSIONS: Self-reported information on the experiences, preferences, beliefs and perceptions about among youth with intellectual disabilities is key for research efforts in health promotion and health disparities.

OBJECTIVE: To assess whether a Smarter Lunchroom intervention based on behavioural economics and adapted for students with intellectual and developmental disabilities would increase the selection and consumption of fruits, vegetables and whole grains, and reduce the selection and consumption of refined grains. DESIGN: The 3-month intervention took place at a residential school between March and June 2012. The evaluation employed a quasi-experimental, pre-post design comparing five matched days of dietary data. Selection and plate waste of foods at lunch were assessed using digital photography. Consumption was estimated from plate waste. SETTING: Massachusetts, USA. SUBJECTS: Students (n 43) aged 11-22 years with intellectual and developmental disabilities attending a residential school. RESULTS: Daily selection of whole grains increased by a mean of 0·44 servings (baseline 1·62 servings, P = 0·005) and refined grains decreased by a mean of 0·33 servings (baseline 0·82 servings, P = 0·005). The daily consumption of fruits increased by a mean of 0·18 servings (baseline 0·39 servings, P = 0·008), whole grains increased by 0·38 servings (baseline 1·44 servings, P = 0·008) and refined grains decreased by a mean of 0·31 servings (baseline 0·68 servings, P = 0·004). Total kilojoules and total gram weight of food selected and consumed were unchanged. Fruit (P = 0·04) and vegetable (P = 0·03) plate waste decreased. CONCLUSIONS: A Smarter Lunchroom intervention significantly increased whole grain selection and consumption, reduced refined grain selection and consumption, increased fruit consumption, and reduced fruit and vegetable plate waste. Nudge approaches may be effective for improving the food selection and consumption habits of adolescents and young adults with intellectual and developmental disabilities.

The authors compared physical activity enjoyment, perceived barriers, beliefs, and self-efficacy between adolescents with autism spectrum disorder (ASD) and typically developing (TD) adolescents. A questionnaire was verbally administered to 35 adolescents with ASD and 60 TD adolescents. Compared with TD adolescents, fewer adolescents with ASD enjoyed team sports (65% vs. 95%, p < .001) and physical education (84% vs. 98%, p = .02). A greater proportion of adolescents with ASD perceived that physical activities were too hard to learn (16% vs. 0%, p < .01), and fewer believed that physical activity was a way to make friends (68% vs. 97%, p < .001). Fewer adolescents with ASD preferred to do physical activity in their free time (25% vs. 58%, p < .01). Most adolescents with ASD felt that physical activity is fun (84%), but the proportion was lower than in TD adolescents (98%, p = .03). Some perceptions about physical activity were similar between the 2 groups, but differences identified may inform program development.

BACKGROUND: Evidenced-based health promotion programmes for youth with intellectual and developmental disabilities (I/DD) are notably absent. Barriers include a lack of understanding of how to adapt existing evidence-based programmes to their needs, maximize inclusion and support mutual goals of health and autonomy. METHODS: We undertook a community-engaged process to adapt a school-based nutrition intervention in a residential school for youth with I/DD. Focus groups and interviews with school staff elicited recommendations for adaptation strategies; these were then reviewed by an expert panel. RESULTS: Adaptations were developed to address needs in three categories: food-related challenges among students, adjusting to change and transition and social environment factors. Choice and heterogeneity were overarching themes across the adaptation categories. CONCLUSIONS: Future research should consider community-engaged approaches for adaptation so that youth with I/DD can participate and benefit from evidence-based health promotion programmes to their maximum potential.

OBJECTIVE: To assess whether parent training in behavioral intervention, combined with a 16-session nutrition and activity education program, would improve weight loss relative to nutrition and activity education alone in adolescents and young adults with Down syndrome. STUDY DESIGN: Twenty-one patients with Down syndrome aged 13-26 years with a body mass index ≥ 85 th percentile were enrolled and randomized to a 6-month nutrition and activity education intervention (n = 10) or to a nutrition and activity education+behaviorial intervention (n = 11), and followed for 6 months after the active intervention period (1-year follow-up). The primary outcome measure was body weight; secondary outcomes included percentage body fat by bioelectric impedance; intake of fruits, vegetables, and energy-dense low-nutrient snack food (treats) by 3-day food record; and moderate/vigorous physical activity by accelerometry. RESULTS: At 6 months, mean body weight in the nutrition and activity education+behavioral intervention group was 3.2 kg lower than that in the nutrition and activity education group (95% CI, 1.0-5.5 kg; P = .005). Mean group differences were sustained at 1 year (3.6 kg; 95% CI, 1.4-5.9 kg; P = .002). At 6 months, moderate/vigorous physical activity time increased by an average of 18 minutes/day compared with baseline in the nutrition and activity education+behavioral intervention group (P = .01) and decreased by 7 minutes/day in the nutrition and activity education group (P = .30). These changes were largely maintained at 1 year, but were not statistically significant. Vegetable intake in the nutrition and activity education+behavioral intervention group exceeded that in the nutrition and activity education group by a mean of 1.6 servings at 1 year (P = .009), but not at 6 months. No between-group differences were observed for percentage body fat or consumption of fruits or treats. CONCLUSION: Parent-supported behavioral intervention appears to be a successful adjunct to a 6-month nutrition education intervention in achieving weight loss in adolescents and young adults with Down syndrome.

Background: Screen time has been identified as a risk factor for childhood obesity, but the media landscape has evolved rapidly. Children with autism tend to be heavy users of screens and have an elevated prevalence of obesity. We know little about screen use patterns among children with autism vs. typically developing (TD) peers and in association with obesity. Methods: Baseline data from 10,842 participants in the Adolescent Brain Cognition Development Study was used to characterize time spent with child-reported passive screen use (television/movies/watching videos), playing video games, and using social media. Duration of screen time by autism status and gender was summarized as mean time per day; obesity was defined using CDC/WHO criteria. A propensity score analysis was used to create a matched dataset for analysis. Results: Overall, 1.7% of children were was identified as having autism. Significant mean differences were observed by autism status and gender for both passive viewing and playing video games. Compared to TD children, boys with autism spent more time (2.9 vs. 2.3â h, p < 0.001) watching TV, movies or videos, as did girls (3.0 vs. 2.0â h, p = 0.002). Compared to TD peers, boys with autism reported more video game time (102.7 vs. 77.5â min, p = 0.001), as did girls with autism (64.4 vs. 37.9â min, p = 0.03); girls with autism also spent more time on social media sites or video chat (45.5 vs. 21.9â min, p = 0.04). Overall, obesity prevalence increased with increasing screen time duration, significantly for passive screen time (p-value = 0.002) and texting (p-value = 0.02). Associations between obesity and screen time duration did not differ by autism status. Discussion: Children with autism spend more time playing video games and on passive and social screen activities than their TD peers, with some variations by gender. High rates of social media use among girls with autism and multiplayer video game use among both boys and girls with autism may challenge the notion that the high levels of screen time reflect social isolation in the group. Given potential positive aspects of screen time in children with autism movement to focus on content and context is appropriate.
RESUMEN
Background: Children with autism spectrum disorder (ASD) are more likely to have obesity compared to children without ASD, but studies may report biased estimates because of limitations accounting for potentially important factors that may differ between these two groups of children. This study of siblings in "simplex" families (i.e., families that include only one offspring with ASD) avoids these potential pitfalls. Methods: The Simons Simplex Collection was used to create sibling dyads comprising a child with a clinically confirmed diagnosis of ASD and a full sibling without ASD within the same biological family. Child obesity, determined from measured heights and weights, was compared across three child age strata (4-7.9, 8-10.9, 11-18.0 years) and by parents' weight status using generalized estimating equations log-binomial regression models. Results: Among 1378 sibling dyads, 4-18 years of age, the prevalence of obesity significantly increased with age, with larger sibling differences at older ages. For ages 4-7.9 years, the obesity prevalence for children with ASD was 15.0% compared to 16.2% for siblings (p = 0.57). For ages 11-18.0 years, prevalence for children with ASD was 30.7% compared to 21.4% for siblings (p = 0.003). Parental obesity significantly affected sibling obesity. Conclusion: From this unique data resource that accounted for shared family environments, the prevalence of obesity diverged significantly at older ages between children with ASD and their full siblings without ASD and was associated with parental obesity status similarly for children with and without a diagnosis of ASD. Recognizing these age-related differences has important implications for targeting preventive interventions.

Background: Health disparities faced by autistic youth are exacerbated by inadequate physical activity (PA) and sleep, whereas healthy PA and sleep may improve mood and function. Adaptive Game Squad (AGS) is an evidence-based telehealth coaching and exergaming intervention to improve PA and sleep for adolescents with diverse neurodevelopmental and psychiatric conditions. This study aimed to adapt AGS for autistic youth ages 10-15 years; beta-test the modified intervention for feasibility, accessibility, and engagement; and further refine the intervention for a larger planned demonstration pilot. Methods: Interdisciplinary experts adapted AGS to create GamerFit-ASD, a 12-week intervention that included a progressive exergame schedule, Fitbit step-tracking, weekly health coaching, and health tip/exercise videos. For beta testing, the intervention was shortened to a 4-week trial with 5 parent/child dyads. Children completed exit surveys and parents and children were interviewed about intervention feasibility, accessibility, and engagement. Exit survey data were summarized with descriptive statistics. Qualitative data were analyzed using a modified grounded-theory approach. Results: All participants (n = 5; ages 10-14 years) attended all 4 planned coaching sessions and completed an average of 9 of 12 planned exergame challenges for a weekly average of 50â min. All participants reported enjoying coaching sessions, 4 of 5 reported enjoying exergames, and 3 of 5 reported enjoying on-demand exercise videos. In interviews, children generally reported finding participation feasible, exergaming challenges active and fun, and coaches friendly and helpful. Parents reported high feasibility of supporting their children's involvement and valued child goal-setting and intervention flexibility; however, some found telehealth sessions overly scripted. Several adaptations to coaching scripts, coach training, and parent materials were made for the larger demonstration pilot, including changes to reduce scriptedness of coaching sessions, to provide parents with more information specific to autism, and to make video content more appropriate to children's needs/preferences. Discussion: A telehealth coaching and exergaming intervention appears feasible, accessible, and engaging for autistic youth aged 10-15. Future studies with larger, more diverse samples, longer study durations and/or follow-up periods, and more rigorous study designs are needed to advance understanding of the appropriateness and effectiveness of this type of intervention for this population.
RESUMEN
Background: The consequences of obesity are ominous, yet healthcare professionals are not adequately preventing or treating obesity in youth with Down syndrome (DS). Total daily energy expenditure (TDEE) is the energy expended in 24â h through physical activity and life-sustaining physiologic processes. An individual's TDEE is essential for determining the daily caloric intake needed to maintain or change body weight. Successful prevention and treatment of obesity in youth with DS is severely compromised by the lack of data on TDEE and information on weight-related behaviors for this high-risk population. This manuscript describes the protocol for the federally funded study that is in process to determine daily energy expenditure in a large cohort of children with DS. Methods: This observational cross-sectional study will include a national sample of 230 youth with DS, stratified by age (5-11 and 12-18 years of age) and sex. Doubly Labeled Water analysis will provide the criterion body fat%, fat-free mass, and TDEE. To increase accessibility and decrease the burden on participants, the entire study, including obtaining consent and data collection, is conducted virtually within the participant's home environment on weekdays and weekends. The study team supervises all data collection via a video conferencing platform, e.g., Zoom. This study will (1) examine and determine average TDEE based on age and sex, (2) develop a prediction equation based on measured TDEE to predict energy requirements with a best-fit model based on fat-free mass, sex, age, and height and/or weight, and (3) use 24-hour dietary recalls, a nutrition and physical activity screener, wearable devices, and sleep questionnaire to describe the patterns and quality of dietary intake, sleep, and physical activity status in youth with DS. Discussion: The lack of accurate information on energy expenditure and weight-related behaviors in youth with DS significantly impedes the successful prevention and treatment of obesity for this vulnerable population. The findings of this study will provide a further understanding of weight-related behaviors as obesity risk factors, currently not well understood for this population. This study will advance the science of weight management in individuals with disabilities and shift clinical practice paradigms.
RESUMEN
Adolescent girls with intellectual disabilities (ID) are at risk for low physical activity (PA) participation due to their limited opportunities. PURPOSE: To evaluate the feasibility and preliminary efficacy of a 12-week dance intervention to promote engagement in moderate-to-vigorous PA (MVPA) and increase cardiorespiratory fitness. METHODS: The 12-week intervention included two 75-min weekly dance sessions. Continuous heart-rate (HR) monitoring assessed time spent below/at/above each girl's target HR zone. Cardiorespiratory fitness was measured by the 6-min walk test (6MWT). Survey items assessed participant enjoyment and participant and parent satisfaction. RESULTS: The mean (SD) age of 18 adolescent girls was 17.3 (2.7) years. Overall, girls attended 88% of sessions and spent 52.3% of each session in MVPA. Mean MVPA was unchanged across the 12 weeks, but the pattern differed across the three sites. We observed a non-significant pre-post increase of 74.6 feet on the 6MWT. Post-intervention surveys indicated that most girls liked the program, perceived improved fitness, and wished to continue dancing. The majority also reported a preference for a girls-only dance program exclusively for those with ID. CONCLUSION: Our findings suggest that dance is viable for promoting PA for girls with ID. More frequent exercise training is likely needed to improve cardiorespiratory fitness.

BACKGROUND: Scant data exist on weight loss interventions for youth with intellectual disabilities (ID). OBJECTIVE: To compare weight loss among youth with ID randomized to a 6-month, family-based behavioural intervention (FBBI) or a waitlist and to compare weight loss among youth who completed a 6-month maintenance (FBBI-M) intervention to a control group (FBBI-C). METHODS: Youth with ID and overweight/obesity, aged 14-22 years, were randomized to the FBBI or to a waitlist and subsequently randomized to a maintenance intervention or a control group. Sessions were held weekly during the FBBI and biweekly during the FBBI-M. Using an intention-to-treat approach, we used linear mixed models to test differences in the change in weight and in BMI from the start of FBBI. RESULTS: The 24 participants who received the FBBI lost, on average (SE), 5.1 (1.1) kg (P < .001) over 6 months. The 13 participants who were waitlisted gained, on average (SE), 1.2 (1.6) kg over the 6-month waiting period. At 12 months, those who received FBBI-M lost, on average (SE), 4.4 (1.7) kg more than those who received FBBI-C (-7.6 vs -3.2 kg, P-value = .008). CONCLUSION: Participation in an intensive FBBI for weight loss with ID was efficacious, and continued participation in a maintenance intervention yielded additional weight loss.

PURPOSE: To identify the accuracy of Body Mass Index (BMI) to categorize body weight in a sample of children with spina bifida and Down syndrome as compared to typically developing peers. METHODS: A secondary analysis of 32 children with spina bifida, Down syndrome or no chronic illness. A calculated BMI was plotted on the Centers for Disease Control and Prevention age- and sex-specific BMI growth charts to determine each child's weight status. Percentage of body fat, obtained by labeled water, was plotted on two different body fat percentile reference curves, one derived from a whole body measure (DXA) of body fat and one by skin-fold measure. Differences in weight categories between calculated BMI and body fat percentile curves were reported. RESULTS: The calculated BMI for children with a disability had significant misclassifications as a screening tool for body fat when compared to children without a disability. Misclassifications were increased with the body fat percentile reference curve derived from skin-fold measures and for children who primarily used a wheelchair. CONCLUSION: The current recommendation to use BMI to categorize weight status is not useful for many children with disabilities. Further research to identify an alternative pragmatic strategy is necessary.

Analysis of a population-based, nationally-representative longitudinal sample from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 identified an increase in healthy-weight children with autism spectrum disorder becoming overweight and obese between first and second grade, thus identifying a critical period for early prevention and treatment.
RESUMEN
BACKGROUND: The prevalence of neurodevelopmental and psychiatric diagnoses (NPDs) in youth is increasing, and unhealthy physical activity (PA), diet, screen time, and sleep habits contribute to the chronic disease disparities and behavioral challenges this population experiences. OBJECTIVE: This pilot study aims to adapt a proven exergaming and telehealth PA coaching intervention for typically developing youth with overweight or obesity; expand it to address diet, screen, and sleep behaviors; and then test its feasibility and acceptability, including PA engagement, among youth with NPDs. METHODS: Participants (N=23; mean age 15.1 years, SD 1.5; 17 males, 9 people of color) recruited in person from clinic and special education settings were randomized to the Adaptive GameSquad (AGS) intervention or wait-list control. The 10-week adapted intervention included 3 exergaming sessions per week and 6 real-time telehealth coaching sessions. The primary outcomes included feasibility (adherence to planned sessions), engagement (uptake and acceptability as reported on process questionnaires), and PA level (combined light, moderate, and vigorous as measured by accelerometer). Descriptive statistics summarized feasibility and engagement data, whereas paired, two-tailed t tests assessed group differences in pre-post PA. RESULTS: Of the 6 coaching sessions, AGS participants (n=11; mean age 15.3 years, SD 1.2; 7 males, 4 people of color) completed an average of 5 (83%), averaging 81.2 minutes per week of exergaming. Of 9 participants who completed the exit questionnaire, 6 (67%) reported intention to continue, and 8 (89%) reported feeling that the coaching sessions were helpful. PA and sleep appeared to increase during the course of the intervention over baseline, video game use appeared to decrease, and pre-post intervention PA per day significantly decreased for the control (-58.8 min; P=.04) but not for the intervention group (-5.3 min; P=.77), despite potential seasonality effects. However, beta testers and some intervention participants indicated a need for reduced complexity of technology and more choice in exergames. CONCLUSIONS: AGS shows promise in delivering a health behavior intervention remotely to youth with NPDs, but a full-scale efficacy trial with a larger sample size is needed to confirm this finding. On the basis of feedback from beta testers and intervention participants, the next steps should include reduced technology burden and increased exergame choice before efficacy testing.
