Access to physical activity promotion for people with neurological conditions: Are physical therapists leading the way?

BACKGROUND: People with neurological conditions (NCs) engage in physical activity (PA) at a lower rate than those without disabilities. Physical therapists (PTs) are positioned to provide PA promotion; however, less is known about the consistency of promoting PA for their patients with NC. OBJECTIVE: The objective of this study was to investigate the frequency of PA promotion of PTs who treat patients with NC, the factors associated with PA promotion, and the types of PA promotion used. METHODS: An online survey that assessed the aspects of PA promotion frequency and behaviors was delivered to a sample of licensed PTs recruited in the United States between February and April of 2022. Descriptive statistics and the equality of proportions test were used to analyze the data. RESULTS: Out of 76 participants who reported working with patients with NC, 34 (45%) reported always promoting PA. Of the 38 participants reporting a caseload of over 50% NC, 17 (45%) reported always promoting PA. Seven factors had a significant correlation with the frequency of PA promotion, and participants reported providing education about PA with their patients (99%). CONCLUSIONS: PTs who work with patients with NC are not consistently promoting PA for their patients. There are opportunities for PTs to learn and apply PA promotion in practice for people with disabilities. The lack of PA promotion by PT may be contributing to the health disparities experienced by people with disabilities particularly those with NC.

GamerFit-ASD beta test: adapting an evidence-based exergaming and telehealth coaching intervention for autistic youth.

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 50 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.

Racial and ethnic disparities in obesity and contributions of social determinants of health among boys with autism spectrum disorder.

Children with autism spectrum disorders (ASD) are at greater obesity risk compared to typically developing peers. Although many potential risk factors for this relationship have been identified, the causal chain must be better understood, particularly modifiable social determinants of obesity risk in ASD, and especially for children with ASD from minoritized racial/ethnic groups. We aimed to: (1) examine racial/ethnic disparities in obesity status in boys with ASD; (2) assess associations between social determinants of health and obesity status; and (3) understand if social determinants of health factors mediate the relationship between race/ethnicity and obesity status for these youth. We used data for 124 boys, aged 9-10 with ASD enrolled in an ongoing longitudinal study. Social determinants of health explored included socioeconomic position, Area Deprivation Index, neighborhood safety, food and housing insecurity, and racial/ethnic discrimination. The racial/ethnic distribution was: 17.1% Black, 14.6% Latino, and 68.3% White; average age was 10 years. Both Black (PR 2.57, 95% CI: 1.26-5.26) and Latino boys (PR 2.08, 95% CI: 1.08-4.03) with ASD were more likely to be obese than their White peers. While there were significant differences in some social determinants of health by race/ethnicity, only food insecurity mediated associations between race/ethnicity (Black vs. White) and obesity. The striking disparities in obesity and differences in social determinants of health between Black and Latino children with ASD compared to White children emphasize the need to identify factors that contribute to healthy weight among these children and to address these factors in practice.

Passive and social screen time in children with autism and in association with obesity.

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. 2.3 h, p < 0.001) watching TV, movies or videos, as did girls (3.0 vs. 2.0 h, p = 0.002). Compared to TD peers, boys with autism reported more video game time (102.7 vs. 77.5 min, p = 0.001), as did girls with autism (64.4 vs. 37.9 min, p = 0.03); girls with autism also spent more time on social media sites or video chat (45.5 vs. 21.9 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.

An 8-Week Peer Health Coaching Intervention among College Students: A Pilot Randomized Study.

This study explored the effects of an 8-week peer coaching program on physical activity (PA), diet, sleep, social isolation, and mental health among college students in the United States. A total of 52 college students were recruited and randomized to the coaching (n = 28) or the control group (n = 24). The coaching group met with a trained peer health coach once a week for 8 weeks focusing on self-selected wellness domains. Coaching techniques included reflective listening, motivational interviews, and goal setting. The control group received a wellness handbook. PA, self-efficacy for eating healthy foods, quality of sleep, social isolation, positive affect and well-being, anxiety, and cognitive function were measured. No interaction effects between time and group were significant for the overall intervention group (all p > 0.05), while the main effects of group difference on moderate PA and total PA were significant (p < 0.05). Goal-specific analysis showed that, compared to the control group, those who had a PA goal significantly increased vigorous PA Metabolic Equivalent of Task (METs) (p < 0.05). The vigorous METs for the PA goal group increased from 1013.33 (SD = 1055.12) to 1578.67 (SD = 1354.09); the control group decreased from 1012.94 (SD = 1322.943) to 682.11 (SD = 754.89); having a stress goal significantly predicted a higher post-coaching positive affect and well-being, controlling the pre-score and other demographic factors: B = 0.37 and p < 0.05. Peer coaching showed a promising effect on improving PA and positive affect and well-being among college students.

Relationship Between Childhood Obesity and Autism Spectrum Disorder Varies by Child's Age and Parents' Weight Status in a Sample of Sibling Dyads.

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.

Child ADHD and autistic traits, eating behaviours and weight: A population-based study.

BACKGROUND: Children with Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) have an increased obesity risk. Although these conditions commonly co-occur, shared factors relating to obesity risk are unknown. OBJECTIVES: To examine the shared and unique associations of ADHD and autistic traits with eating behaviours and BMI. METHODS: Children (N = 4134) from the population-based Generation R Study were categorized into subgroups based on parent-reported ADHD and autistic traits scores at 6 years: ADHDHigh , ASDHigh , ADHD+ASDHigh and REF (reference group: ADHD+ASDLow ). Multiple linear regressions examined the associations between subgroups and eating behaviours (at 10 years) and BMIz (at 14 years), relative to REF. Mediation analyses tested the indirect effect of subgroup and BMIz through eating behaviours. RESULTS: ADHD + ASDHigh children expressed both food approach (increased food responsiveness and emotional overeating) and avoidant eating behaviours (increased emotional undereating, satiety responsiveness/ slowness in eating and picky eating, and decreased enjoyment in food). ASDHigh children were more food avoidant, while ADHDHigh children had more food approach behaviours and greater BMIz. ADHDHigh and BMIz were indirectly associated with food responsiveness and emotional overeating. CONCLUSIONS: ADHD and autistic trait phenotypes show distinct associations with potential obesity risk factors, and further research is needed to improve targeted early intervention.

Presenting a New Framework to Improve Engagement in Physical Activity Programs for Children and Adolescents With Social, Emotional, and Behavioral Disabilities.

Children and adolescents with psychiatric and neurodevelopmental diagnoses such as anxiety, depression, autism, and attention-deficit/hyperactivity disorder (ADHD) face enormous health disparities, and the prevalence of these disorders is increasing. Social, emotional, and behavioral disabilities (SEBD) often co-occur with each other and are associated with unique barriers to engaging in free-living physical activity (PA), community-based exercise and sports programming, and school-based physical education. Some examples of these barriers include the significantly depleted parental reserve capacity associated with SEBD in children, child dysregulation, and previous negative experiences with PA programming and/or exclusion. Importantly, most SEBD are "invisible," so these parents and children may face more stigma, have less support, and fewer inclusive programming opportunities than are typically available for children with physical or intellectual disabilities. Children's challenging behavioral characteristics are not visibly attributable to a medical or physical condition, and thus are not often viewed empathetically, and cannot easily be managed in the context of programming. Existing research into PA engagement barriers and facilitators shows significant gaps in existing health behavior change (HBC) theories and implementation frameworks that result in a failure to address unique needs of youth with SEBD and their parents. Addressing these gaps necessitates the creation of a simple but comprehensive framework that can better guide the development and implementation of engaging, effective, and scalable PA programming for these youth and their families. Therefore, the aim of this article is to: (1) summarize existing research into SEBD-related child and parent-level barriers and facilitators of PA evidence-based program engagement; (2) review the application of the most commonly used HBC and disability health theories used in the development of evidence-based PA programs, and implementation science frameworks used in adaptation and dissemination efforts; (3) review the SEBD-related gaps that may negatively affect engagement; and (4) describe the new Pediatric Physical Activity Engagement for Invisible Social, Emotional, and Behavioral Disabilities (PAID) Framework, a comprehensive adapted PA intervention development and implementation adaptation framework that we created specifically for youth with SEBD and their parents.

Adapting Active Science to PE Curricula: Examining Feasibility and Acceptability in Low-Income, Urban Public Schools.

Purpose: Children in low-income, urban areas are at a greater risk of poor physical activity (PA) and academic outcomes. The purpose of this study was to examine feasibility, acceptability, and engagement of a pilot implementation of the Active Science (AS) exer-learning program in 3rd grade physical education (PE) classes to inform potential upscaling after efficacy evaluation. Methods: AS was implemented within PE at five public schools serving low-income, urban neighborhoods, using a phased implementation approach. A mixed methods approach was utilized; feasibility and engagement were measured using quantitative dose and fidelity measures, students were surveyed regarding acceptability, and PE teachers were interviewed pre/post-intervention regarding perceptions of the program. Results: N = 638 students in k = 25 PE classes across five schools averaged 8.8 weeks of AS implementation with nearly universal inclusivity. Students averaged 1468 steps/session; an average of 15% of available PE class time was spent in MVPA. Semi-structured interviews revealed high staff perceptions of feasibility, as well as specific improvements that should be implemented before upscaling. Conclusions: Process and PA measures indicate high feasibility, with excellent engagement across all five schools. Together with high acceptability reported by students and staff, these results show that AS can feasibly integrate into PE classes low-income, urban schools to improve student engagement in both PA and science learning.

Barriers and facilitators to physical education, sport, and physical activity program participation among children and adolescents with psychiatric disorders: a systematic review.

Children and adolescents with heterogeneous psychiatric disorders, of whom over 50% have a second psychiatric comorbidity, have low rates of physical activity and experience unique challenges to engaging in community-based exercise programming, school-based physical education programming, and targeted physical activity interventions. This contributes to elevated rates of gross and fine motor delays, lower mood and self-regulation, and increased risk of chronic diseases such as obesity and type 2 diabetes. Perform a systematic scoping review of the literature to assess known barriers to and facilitators of engaging in physical activity programming among children and adolescents with heterogeneous and/or comorbid psychiatric disorders, in order to improve engagement among this population in real world intervention settings. Systematic Boolean diagnostic and physical activity search terms were entered into PubMed, MEDLINE, PsycINFO and Web of Science for English-language studies published between 2005 and 2020, examining barriers and facilitators for common psychiatric diagnoses and general psychiatric population's engagement in physical activity, physical education, sports, or exercise interventions. Two reviewers independently reviewed titles, abstracts and full articles to determine inclusion. A total of 5,198 articles were returned; 39 relating to children and adolescents were qualified for full-text review. After review, 24 studies were included addressing barriers and facilitators across multiple diagnoses; 7 studies were quantitative, 10 were qualitative, and 7 were mixed methods. Major barriers included low motivation, low self-efficacy, depleted parental reserve capacity, social isolation, lack of staff training, and safety concerns. Major facilitators included peer support/engagement, exergames, supportive parental behaviors, and inclusive/adaptive programming. Numerous barriers and facilitators to physical activity have been identified which should inform community, school, clinical, and research intervention program design. Further research is needed to develop effective strategies that address the challenges to inclusion that children and adolescents with heterogeneous and/or comorbid psychiatric disorders face.

The Adaptive GameSquad Xbox-Based Physical Activity and Health Coaching Intervention for Youth With Neurodevelopmental and Psychiatric Diagnoses: Pilot Feasibility Study.

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.

Promoting Sleep and Balanced Screen Time among School-Aged Children with Neurodevelopmental and Mental Health Disorders: A Parent Perspective.

Background: Children with neurodevelopmental and mental health disorders (N/MHD), such as autism spectrum, mood disorders, and anxiety, are more likely to engage in excessive screen time, receive insufficient sleep, and to have obesity than neurotypical peers. However, little is known about how parents of these children approach promoting sleep and balanced screen time. Methods: We conducted semistructured interviews with 24 parents of children aged 8-15 years with a diagnosis of N/MHD to assess barriers and facilitators to promoting sleep and balanced screen time. Interviews were transcribed, double-coded using constant comparative methods, and summarized into themes using NVivo 11. Results: Many parents described children's chronic sleep challenges, often compounded by screen use and no clear solutions. When feeling overwhelmed, some parents reluctantly reported co-sleeping or allowing gaming devices in bed. Nearly all participants reported chronic, occasionally severe, conflict when managing children's screen time, with some parents experiencing opposition and physical aggression. Parents struggled to weigh the benefits of screen use (i.e., behavior management, learning, and social connection) with the costs (i.e., reduced self-care and limited physical activity). To combat barriers, parents described firm routines (i.e., "screens off" time and consistent bedtime on weekdays and weekends), moderating access (i.e., shutting down internet and no device in bedroom), verbal priming, and coping strategies (i.e., music and books). Conclusions: Parents of children with N/MHD face unique challenges in promoting sleep and balanced screen time. Given these behaviors may impact weight status and mental health, future interventions should examine ways to support parents in reducing conflict while promoting healthy habits.

Do ADHD-impulsivity and BMI have shared polygenic and neural correlates?

There is an extensive body of literature linking ADHD to overweight and obesity. Research indicates that impulsivity features of ADHD account for a degree of this overlap. The neural and polygenic correlates of this association have not been thoroughly examined. In participants of the IMAGEN study, we found that impulsivity symptoms and body mass index (BMI) were associated (r = 0.10, n = 874, p = 0.014 FWE corrected), as were their respective polygenic risk scores (PRS) (r = 0.17, n = 874, p = 6.5 × 10-6 FWE corrected). We then examined whether the phenotypes of impulsivity and BMI, and the PRS scores of ADHD and BMI, shared common associations with whole-brain grey matter and the Monetary Incentive Delay fMRI task, which associates with reward-related impulsivity. A sparse partial least squared analysis (sPLS) revealed a shared neural substrate that associated with both the phenotypes and PRS scores. In a last step, we conducted a bias corrected bootstrapped mediation analysis with the neural substrate score from the sPLS as the mediator. The ADHD PRS associated with impulsivity symptoms (b = 0.006, 90% CIs = 0.001, 0.019) and BMI (b = 0.009, 90% CIs = 0.001, 0.025) via the neuroimaging substrate. The BMI PRS associated with BMI (b = 0.014, 95% CIs = 0.003, 0.033) and impulsivity symptoms (b = 0.009, 90% CIs = 0.001, 0.025) via the neuroimaging substrate. A common neural substrate may (in part) underpin shared genetic liability for ADHD and BMI and the manifestation of their (observable) phenotypic association.

Shaping healthy habits in children with neurodevelopmental and mental health disorders: parent perceptions of barriers, facilitators and promising strategies.

OBJECTIVE: Prevalence of pediatric neurodevelopmental and mental health disorders (ND/MHD) is increasing in the United States and globally. ND/MHD are associated with higher risk of poor dietary, physical activity (PA), screen, and sleep habits in youth, contributing to elevated lifetime chronic disease risk. ND/MHD symptoms can present unique challenges to parenting, create competing parenting priorities, and may decrease parental capacity to instill healthy habits. Unfortunately, literature characterizing parenting of health habits in youth with ND/MHD is sparse. The objective of this study was to describe barriers to, facilitators of, and practical strategies for parenting healthy lifestyle habits in children and teens with ND/MHD. METHODS: We conducted semi-structured interviews with parents whose children with diagnosed ND/MHD were attending a Boston-area therapeutic day school serving K-10th grade. Interviews allowed parents to focus on parenting PA, diet, sleep, and/or screen habits as context for questions. Interviews were transcribed, double-coded using constant comparative methods, and summarized into themes using NVivo 11. RESULTS: We interviewed 24 parents; average age of their child with ND/MHD was 11.2 years (range: 8-15). Most had a son (75%) with multiple ND/MHD (88%); diagnoses included autism spectrum disorder (50%), attention deficit-hyperactivity disorder (67%), anxiety (67%), and other mood disorders (58%). Major barriers to parenting all types of health habits included depleted parent resources, child dysregulation, lack of supportive programming available to children with ND/MHD, and medication side effects. Major facilitators included participation in specialized therapeutic options, adaptive community programs and schools, as well as parents' social capital. Effective parenting strategies included setting clear, often structural boundaries, using positive reinforcement, allowing agency by presenting healthy choices, and use of role modeling to promote healthy habits. Almost one third of parents extensively discussed the role of pets or therapy animals as key to establishing and maintaining healthy routines, particularly PA and screen-time management. CONCLUSIONS: Parenting healthy habits in children with ND/MHD is difficult and is undermined by competing demands on parenting resources. To reduce chronic disease disparities and promote health in this population, future research must better adapt existing health promotion materials and programs to more practically support parents in multiple settings including home, schools and community organizations.

Children's Attention-Deficit/Hyperactivity Disorder Symptoms Predict Lower Diet Quality but Not Vice Versa: Results from Bidirectional Analyses in a Population-Based Cohort.

BACKGROUND: As an adjuvant for medication, dietary changes focused on specific nutrients have been proposed to prevent or reduce attention-deficit/hyperactivity disorder (ADHD) symptoms. However, whether an overall healthy dietary pattern is associated with ADHD symptom severity during childhood remains unclear. Furthermore, it is not clear what the direction of this association is. OBJECTIVES: We aimed to examine the association between dietary patterns and ADHD symptoms in school-aged children. In addition, we aimed to identify the temporal direction of this association-that is, whether dietary patterns predict ADHD symptoms or vice versa. METHODS: We analyzed data from 3680 children participating in the Generation R Study, a prospective cohort in Rotterdam, Netherlands. ADHD symptoms were assessed with parent-report questionnaires at ages 6 and 10 y using the Child Behavior Checklist. Dietary intake was assessed at the age of 8 y with a validated food-frequency questionnaire. We computed a diet quality score reflecting adherence to dietary guidelines. We examined bidirectional associations of diet quality with ADHD symptom scores using multivariable linear regression analysis and cross-lagged modeling. RESULTS: Linear regressions showed that more ADHD symptoms at age 6 y were associated with a lower diet quality score at age 8 y (SD score = -0.08; 95% CI: -0.11, -0.05) but that diet quality at age 8 y was not associated with ADHD symptoms at age 10 y. Cross-lagged models confirmed a unidirectional relation from ADHD symptoms to diet quality but not vice versa. Associations did not differ by overweight status or between boys and girls. CONCLUSION: Our study suggests that children with more ADHD symptoms may be at higher risk of an unhealthy diet but that overall diet quality does not affect ADHD risk.

ADHD Medication, Dietary Patterns, Physical Activity, and BMI in Children: A Longitudinal Analysis of the ECLS-K Study.

OBJECTIVE: This study examined relationships between attention-deficit/hyperactivity disorder (ADHD), stimulant use, and BMI change in a nationally representative cohort of children as well as differences in diet and physical activity that may mediate associations between stimulant use and BMI change. METHODS: By using the Early Childhood Longitudinal Study-Kindergarten Cohort 1998-1999 (N = 8,250), we modeled BMI and z score change by ADHD and stimulant start time, examined the odds of unhealthy diet and physical activity predicted by ADHD and stimulant use, and performed mediation analysis assessing indirect effects of health behaviors. RESULTS: Early stimulant use predicted short-term BMI reductions, but any stimulant use predicted increased BMI growth between fifth grade (mean age = 11.2 years) and eighth grade (mean age = 14.3 years). Children with ADHD had higher odds of poor diet regardless of medication. Health behaviors were not associated with BMI change after controlling for medication use. CONCLUSIONS: Stimulant use predicted higher BMI trajectory between fifth and eighth grade but did not affect dietary or physical activity patterns. Future research should explore potential mechanisms by which early and long-term stimulant use may affect metabolism, while clinicians should initiate nutrition counseling with families of children with ADHD, regardless of medication prescription, at or shortly after diagnosis.

Physical Activity Interventions for Children with Social, Emotional, and Behavioral Disabilities-A Systematic Review.

OBJECTIVE: Perform a systematic review of the available literature regarding the effectiveness of exercise interventions on children with any type of social, emotional, or behavioral disability (SEBD), with attention to a range of physiological, behavioral, and mood outcomes. METHODS: Six databases were searched using a systematic methodology. References of included studies, as well as relevant reviews, were also examined. The review was limited to studies published since 2000 reporting a quantitative analysis of the effects of a physical activity (PA) intervention on at least 1 behavioral, psychological, or cognitive outcome in children aged 21 and under, diagnosed with a SEBD. Only studies with a control group were included. RESULTS: We identified 24 eligible studies. Studies varied in design, participant characteristics, and intervention characteristics (single-bout vs repeated exposure, duration, intensity level, mode of exercise). Of the 20 behavioral outcome assessments, there was 1 negative finding, 12 null findings, 5 positive findings, and 2 mixed findings. For the 25 executive functioning outcome assessments, there were 5 null findings, 18 positive findings, and 2 mixed findings. For the remaining outcome domains, 1 of 2 studies looking at academic performance, 3 of 6 studies looking at objective neurological measures, and 1 of 3 studies looking at affect outcomes found positive results. All other results were null or mixed. CONCLUSION: Although additional research is warranted to further understand the mechanisms by which PA affects behavioral and cognitive outcome measures in children with SEBDs, PA offers a safe and alternative form of treatment for this population.

Cybercycling Effects on Classroom Behavior in Children With Behavioral Health Disorders: An RCT.

BACKGROUND AND OBJECTIVES: Exercise is linked with improved cognition and behavior in children in clinical and experimental settings. This translational study examined if an aerobic cybercycling intervention integrated into physical education (PE) resulted in improvements in behavioral self-regulation and classroom functioning among children with mental health disabilities attending a therapeutic day school. METHODS: Using a 14-week crossover design, students (N = 103) were randomly assigned by classroom (k = 14) to receive the 7-week aerobic cybercycling PE curriculum during fall 2014 or spring 2015. During the intervention, children used the bikes 2 times per week during 30- to 40-minute PE classes. During the control period, children participated in standard nonaerobic PE. Mixed effects logistic regression was used to assess relationships between intervention exposures and clinical thresholds of behavioral outcomes, accounting for both individual and classroom random effects. RESULTS: Children experienced 32% to 51% lower odds of poor self-regulation and learning-inhibiting disciplinary time out of class when participating in the intervention; this result is both clinically and statistically significant. Effects were appreciably more pronounced on days that children participated in the aerobic exercise, but carryover effects were also observed. CONCLUSIONS: Aerobic cybercycling PE shows promise for improving self-regulation and classroom functioning among children with complex behavioral health disorders. This school-based exercise intervention may significantly improve child behavioral health without increasing parental burden or health care costs, or disrupting academic schedules.

A cybercycling intervention to improve behavioral regulation and classroom functioning among children with behavioral health disorders: Pragmatic randomized trial design for Manville Moves.

While positive and clinically meaningful effects of exercise on cognition and behavior in children have been demonstrated in controlled experimental settings, they have rarely been translated and rigorously evaluated in real-world environments. In particular, there is a lack of research on school-based approaches to sustainable physical activity and exercise interventions targeting children with behavioral health disorders. Manville Moves is an exercise intervention designed to improve behavioral regulation and classroom functioning among children with neurodevelopmental and affective disorders within a therapeutic day-school environment. The curriculum is built around virtual-reality exergaming bicycles (cybercycles) and integrated into physical education (PE) classes. Manville Moves was developed using community based participatory research (CBPR) and implemented as a pragmatic trial. In this paper, we describe (a) the background, theoretical framework and intervention setting, (b) the Manville Moves curriculum, (c) the study design and outcome and process measures, and (d) the strategies used to support implementation compliance and intervention uptake by a population with a variety of behavioral challenges. We conclude with a detailed description of the participatory process by which the intervention was developed and integrated into school programming and a review of the program's key innovations and approaches to addressing threats to internal and external validity.
