Acute Effects of Walking and Standing on Executive Function in Children with Attention Deficit/Hyperactivity Disorder: A Feasibility Study.

Children with attention deficit/hyperactivity disorder (ADHD) struggle with executive functioning (EF). While physical activity (PA) benefits EF, little is known about the impact of specific activities like standing. The purpose of this study was to evaluate the feasibility of performing a rigorous experimental study to compare the effects of walking and standing on EF in children with ADHD. Six areas of feasibility were assessed: recruitment, randomization, treatment adherence, retention, acceptability of the intervention, and implementation. A randomized pilot study using three parallel conditions compared the effects of two modes of activity on EF in children 6-11 with ADHD. While there were no significant differences between walking and standing for EF, analyses suggest that it is feasible to compare effects of standing vs. walking on EF among children with ADHD. This study supports the feasibility of undertaking a larger scale study to evaluate the effect of standing on EF in children with ADHD.

Does physical activity differ between youth with and without intellectual disabilities?

BACKGROUND: Children and youth with intellectual disabilities (ID) are known to face obstacles to physical activity participation, yet the activity patterns of this population are not well characterized. OBJECTIVE/HYPOTHESIS: In this study, time spent in moderate to vigorous physical activity (MVPA), type, and frequency of participation in physical activities were assessed in youth with ID and in a comparison group of typically developing (TD) youth. METHODS: Weekly participation in MVPA in 38 youth with ID and 60 TD youth was assessed via accelerometry. Participants were also administered an interview about the frequency and type of physical activities they engaged in over the past year. RESULTS: After adjusting for age and sex, youth with ID spent significantly less time in MVPA (33.5 vs. 46.5 min/day, p = 0.03) and were less likely to meet the US Physical Activity Guidelines than TD youth (6% vs. 29%, p = 0.01). Although time in MVPA was lower in youth with ID, females with ID participated in physical activities more frequently than TD females (47.1 vs. 28.2 times/month, p = 0.008) and also reported engaging in a greater variety of physical activities (7.8 vs. 5.2 activities/year, p = 0.01). No differences between males in the frequency of physical activity participation or the number of activities performed were observed. Both groups reported walking/hiking and active video as top activities. CONCLUSIONS: Findings emphasize the need for targeted efforts to increase MVPA in youth with ID.

Interventions to promote physical activity for youth with intellectual disabilities.

OBJECTIVE: To describe interventions designed to promote physical activity for youth with intellectual disabilities. MATERIALS AND METHODS: A systematic review of nine databases until January 31, 2015 identified 213 citations. The inclusion criteria were: a) the study sample consisted of youth with intellectual disabilities, b) the study implemented an intervention to initiate, increase, or maintain physical activity, and c) quantitative or qualitative data were used to report the effectiveness of the intervention. Eleven articles from the 213 citations met this criterion. RESULTS: Nine studies reported significant increases in physical activity behavior. CONCLUSIONS: Conclusions cannot be made regarding intervention components that impacted outcome variables, if the observed effects were specifically due to the intervention or if interventions could be maintained long-term. To advance the knowledge base in this area, a concerted effort should be made to increase rigor in study conceptualization and research design.

Interventions to promote physical activity for adults with intellectual disabilities.

OBJECTIVE: To describe interventions designed to promote physical activity for adults with intellectual disabilities and the effects on overall physical activity levels and on health outcomes. MATERIALS AND METHODS: A systematic review of eight databases until January 31, 2015 identified 383 citations. The inclusion criteria were: a) the study sample consisted of adults with intellectual disabilities, b) the study implemented an intervention to initiate, increase, or maintain physical activity, and c) quantitative or qualitative data were used to report the effectiveness of the intervention. Six articles from the 383 citations met this criterion. RESULTS: Three studies resulted in significant increases in physical activity behaviour; however well-controlled trials designed to improve weight status by increasing physical activity did not produce significant effects. CONCLUSION: Overall, the results indicate that interventions to increase physical activity should simultaneously target the individual with intellectual disability as well as their proximal environment over a sustained period of time.

Physical Activity Levels, Frequency, and Type Among Adolescents with and Without Autism Spectrum Disorder.

We compared time spent in moderate and vigorous physical activity (MVPA), type, and frequency of participation in physical activities between adolescents with ASD (n = 35) and typically developing (TD) adolescents (n = 60). Accelerometers measured MVPA and participants were interviewed about engagement in physical activities. Adolescents with ASD spent less time in MVPA compared to TD adolescents (29 min/day vs. 50 min/day, p < 0.001) and fewer met the Physical Activity Guidelines for Americans (14 vs. 29%, p > 0.05). Among adolescents <16 years old, those with ASD participated in fewer activities than TD adolescents (5.3 vs. 7.1 activities, p < 0.03). Walking/hiking and active video gaming were among the top activities for both groups. Findings support the need for interventions that meet the needs of youth with ASD.

The Effect of Age on the Prevalence of Obesity among US Youth with Autism Spectrum Disorder.

BACKGROUND: We sought to assess the association between age and the prevalence of obesity among children with and without autism spectrum disorder (ASD) in the 2011-2012 National Survey of Children's Health. METHODS: Analyses were restricted to 43,777 children, ages 10-17, with valid measures of parent-reported weight, height, and ASD status. Exploratory analyses describe the impact of sex, race/ethnicity, and household income on the relationship between age and obesity in ASD. RESULTS: Although the overall prevalence of obesity among children with ASD was significantly (p < 0.001) higher than among children without ASD (23.1% vs. 14.1%, 95% confidence interval for difference 3.6 to 14.4), child age significantly (p = 0.035) modified this difference. In a multivariable logistic regression analysis, adjusted for sex, race/ethnicity, and household income, the odds of obesity among children with ASD compared with children without ASD increased monotonically from ages 10 to 17 years. This pattern arose due to a consistently high prevalence of obesity among children with ASD and a decline in prevalence with advancing age among children without ASD. These findings were replicated using a propensity score analysis. Exploratory analyses suggested that the age-related change in obesity disparity between children with and without ASD may be further modified by sex, race/ethnicity, and household income. CONCLUSIONS: The patterns of prevalence observed with increasing age among children with and without ASD were unexpected. A better understanding of the etiological and maintenance factors for obesity in youth with ASD is needed to develop interventions tailored to the specific needs of these children.

Results From the United States of America's 2016 Report Card on Physical Activity for Children and Youth.

BACKGROUND: The 2016 United States (U.S.) Report Card on Physical Activity for Children and Youth provides a comprehensive evaluation of physical activity levels and factors influencing physical activity among children and youth. METHODS: The report card includes 10 indicators: Overall Physical Activity, Sedentary Behavior, Active Transportation, Organized Sport Participation, Active Play, Health-related Fitness, Family and Peers, School, Community and the Built Environment, and Government Strategies and Investments. Nationally representative data were used to evaluate the indicators using a standard grading rubric. RESULTS: Sufficient data were available to assign grades to 7 of the indicators, and these ranged from B- for Community and the Built Environment to F for Active Transportation. Overall Physical Activity received a grade of D- due to the low prevalence of meeting physical activity guidelines. A grade of D was assigned to Health-related Fitness, reflecting the low prevalence of meeting cardiorespiratory fitness standards. Disparities across age, gender, racial/ethnic and socioeconomic groups were observed for several indicators. CONCLUSIONS: Continued poor grades suggest that additional work is required to provide opportunities for U.S. children to be physically active. The observed disparities indicate that special attention should be given to girls, minorities, and those from lower socioeconomic groups when implementing intervention strategies.

Physical Activity Enjoyment, Perceived Barriers, and Beliefs Among Adolescents With and Without Intellectual Disabilities.

BACKGROUND: Youths with intellectual disabilities (ID) exhibit low levels of physical activity, but the underlying contributors to behavior are unclear. We compared physical activity enjoyment, perceived barriers, beliefs, and self-efficacy among adolescents with ID and typically developing (TD) adolescents. METHODS: A questionnaire was administered to 38 adolescents with ID (mean age, 16.8 years) and 60 TD adolescents (mean age, 15.3 years). Of the original 33 questionnaire items, 23 met the test-retest reliability criteria and were included in the group comparisons. RESULTS: Fewer adolescents with ID reported that they have someone with whom to do physical activity (64% vs 93%: P < .001), and a greater percentage of adolescents with ID perceived that physical activities were too hard to learn (41% vs 0%; P < .001). Fewer adolescents with ID believed that physical activity would be good for their health (92% vs 100%; P = .05). More adolescents with ID reported a dislike of individual physical activities (P = .02). A large percentage of adolescents with ID (84%) responded that they were good at doing physical activities, but the difference between groups was only of borderline significance (95% of TD adolescents, P = .06). CONCLUSIONS: Adolescents shared many of the same perceptions about physical activity, but some important differences between groups were identified.

Including Youth with Intellectual Disabilities in Health Promotion Research: Development and Reliability of a Structured Interview to Assess the Correlates of Physical Activity among Youth.

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.

Bone mineral density in adults with Down syndrome, intellectual disability, and nondisabled adults.

Individuals with intellectual disability (ID) or Down syndrome (DS) may be at greater risk of osteoporosis. The purpose of this study was to compare bone mineral density (BMD) of DS, ID, and non-intellectually disabled (NID) populations. In each group, 33 participants between the ages of 28 and 60 years were compared. BMD was measured with dual-energy x-ray absorptiometry (DXA) scans. BMD (p < .0001) between all groups was significantly different. Participants with DS had significantly lower BMD compared to NID participants. Individuals with ID had significantly lower BMD compared to NID subjects. Participants with DS had the lowest BMD of all groups. DS subjects display a greater risk for osteoporosis than ID subjects or control populations.

Efficacy of a peer-guided exercise programme for adolescents with intellectual disability.

BACKGROUND: Peer support is strongly associated with physical activity of adolescents. This study examined the efficacy of a YMCA-based, peer-guided exercise training programme for increasing health-related physical fitness among adolescents with intellectual disabilities. MATERIALS AND METHODS: Adolescents with intellectual disabilities and typically developing peer partners provided reciprocal support during 1-h exercise sessions that included aerobic exercise, weight training and stretching activities. The programme was conducted 2 days/week for 15 weeks and pre- and post-test fitness testing was conducted. RESULTS: Participants demonstrated significant improvements in curl-ups, 6-min walk and BMI. Exercise session attendance was high and participants typically completed all of the prescribed aerobic and stretching exercises, whereas weight training exercises were completed less consistently. CONCLUSIONS: This peer-guided model integrates social and instructional support for adolescents with intellectual disabilities and may encourage exercise participation in community settings.

The feasibility of using a peer-guided model to enhance participation in community-based physical activity for youth with intellectual disability.

We examined the feasibility of a using a peer-guided model to foster participation of youth with intellectual disability in community-based exercise. The intervention was designed to address personal barriers to exercise commonly faced by individuals with intellectual disability. Twenty adolescents with mild-moderate intellectual disability and 14 typically developing peers exercised in groups of two or three, 2 days per week for 15 weeks at YMCAs. Each dyad or triad provided reciprocal support during structured, individualized exercise sessions led by certified fitness trainers. Adherence to the program was high and youth with intellectual disability showed a significant reduction in personal barriers. They also felt they had learned new skills and made new friends. Typically developing youth were also positive about their experience as a volunteer. Our findings suggest that a peer-guided exercise model is useful for enhancing participation in community-based exercise.

Pedometer-measured physical activity of adults with intellectual disability: predicting weekly step counts.

Pedometers are objective, inexpensive, valid, and reliable measures of physical activity. The minimum number of days of pedometer monitoring needed to estimate average weekly step counts was investigated. Seven days of pedometer data were collected from 154 ambulatory men and women (ns = 88 and 66, respectively) with intellectual disability. Correlations between average weekly steps and 3-day combinations ranged from .80 to .94, and adjusted R(2) for 3 days of monitoring was .886. Results suggest that 3 days of pedometer wear is sufficient to predict average weekly steps among ambulatory adults with intellectual disability. This finding will allow researchers to reduce participant burden and study costs, may guide measurement procedures, and inform missing data protocols.

Physical activity of youth with intellectual disability: review and research agenda.

This review characterizes physical activity behavior in youth with intellectual disability (ID) and identifies limitations in the published research. Keyword searches were used to identify articles from MEDLINE, EBSCOhost Research Databases, Psych Articles, Health Source, and SPORT Discus, and ProQuest Dissertations and Theses up to June 2007. Data were extracted from each study using a template of key items that included participant population, study design, data source, and outcome measure. Nineteen manuscripts met the inclusion criteria. Findings were mixed, with various studies indicating that youth with ID have lower, similar, and higher physical activity levels than peers without disabilities. Only two studies provided enough information to determine that some youth with ID were meeting minimum physical activity standards. Significant methodological limitations prohibit clear conclusions regarding physical activity in youth with ID.
