Physical Activity Research in Intellectual Disability: A Scoping Review Using the Behavioral Epidemiological Framework

Understanding capabilities, opportunities and motivations to engage in physical activity for adults with intellectual disabilities: A qualitative evidence synthesis

BACKGROUND

There is a paucity of theory-informed physical activity research with adults with intellectual disabilities. This study aimed to address this by synthesising existing literature and applying the COM-B model to understand capabilities, opportunities and motivations.

METHODS

A qualitative evidence synthesis was conducted and reported in accordance with PRISMA guidelines and the ENTREQ. Three databases were systematically searched up to and including February 2022. Qualitative research relating to the physical activity of adults with intellectual disabilities were included. Thematic synthesis was conducted with themes mapped onto the COM-B model.

RESULTS

Twenty-five studies were included. Influences of physical activity were identified and mapped onto the COM-B model, which also included COM-B influences of social support provided by caregivers.

CONCLUSIONS

There are many complex influences of physical activity for adults with intellectual disabilities. Researchers should consider the influences contributing to caregivers' capacity to support physical activity.

Benefits of inclusive sport training on fitness and health of athletes with and without intellectual disability

Sedentary behaviours in adults with intellectual disabilities (ID) negatively impact health-related determinants and increase the risk of physical dysfunction or chronic health issues. Inclusive sport practice can enhance social inclusion and fitness, benefiting overall person development and life quality. This study aimed to assess fitness level variation in athletes with and without ID before and after a 9-month inclusive (INC) and non-inclusive (N_INC) basketball training. 38 athletes with ID and 14 athletes without ID belonged to INC group, 38 athletes with ID belonged to N_INC group and 23 participants with ID belonged to the control group (CG). Before and after the intervention period, all participants performed anthropometric (body weight, body mass index, body fat percentage) and fitness tests (muscle strength and power, cardiovascular endurance, balance, flexibility, agility, movement speed, and coordination). ID and non-ID athletes of both INC and N_INC groups significantly improved in most of the tests (weight, balance, flexibility, muscle strength, endurance, agility, movement speed and coordination) while CG group significantly worsened weight, muscle endurance, flexibility, agility, movement speed and coordination, after the intervention (p < 0.05). These findings showed that sport training improved fitness in athletes with ID, decreasing health risks. Moreover, involving in the same training group persons with and without disabilities, does not limit the beneficial effects that training induce on persons without ID and could be a valid way to promote both social inclusion and physical health of persons with ID.

Supporting active engagement of adults with intellectual disabilities in lifestyle modification interventions: a realist evidence synthesis of what works, for whom, in what context and why

BACKGROUND

Lifestyle modification interventions for adults with intellectual disabilities have had, to date, mixed effectiveness. This study aimed to understand how lifestyle modification interventions for adults with intellectual disabilities work, for whom they work and in what circumstances.

METHODS

A realist evidence synthesis was conducted that incorporated input from adults with intellectual disabilities and expert researchers. Following the development of an initial programme theory based on key literature and input from people with lived experience and academics working in this field, five major databases (MEDLINE, EMBASE, CINAHL, PsycINFO and ASSIA) and clinical trial repositories were systematically searched. Data from 79 studies were synthesised to develop context, mechanism and outcome configurations (CMOCs).

RESULTS

The contexts and mechanisms identified related to the ability of adults with intellectual disabilities to actively take part in the intervention, which in turn contributes to what works, for whom and in what circumstances. The included CMOCs related to support involvement, negotiating the balance between autonomy and behaviour change, fostering social connectedness and fun, accessibility and suitability of intervention strategies and delivery and broader behavioural pathways to lifestyle change. It is also essential to work with people with lived experiences when developing and evaluating interventions.

CONCLUSIONS

Future lifestyle interventions research should be participatory in nature, and accessible data collection methods should also be explored as a way of including people with severe and profound intellectual disabilities in research. More emphasis should be given to the broader benefits of lifestyle change, such as opportunities for social interaction and connectedness.

Unravelling the link between physical activity and peer social connectedness in young people with intellectual disabilities: a systematic review of quantitative studies

BACKGROUND

There is limited understanding of the context surrounding physical activity (PA) of young people with intellectual disabilities (ID), which has an impact on the development of PA promotion programmes. Peer social connectedness seems to be a vital correlate to focus on, but has not been included in current studies examining the correlates and determinants of PA levels of young people with ID. This study aims to synthesise the evidence on (1) the social constructs researchers have used to conceptualise peer social connectedness in a PA context among young people with ID, (2) the measurement tools that have been used and (3) the relationship between PA and peer social connectedness in young people with ID.

METHODS

The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Ovid MEDLINE, Ovid Embase, Web of Science, ERIC, CINAHL and PsycINFO were searched from 1 January 1996 up to, and including, July 2023 to identify English-language studies, which examined associations between PA and peer social connectedness in adolescents and young adults (13-24 years) with ID. Study quality was assessed using the Standard Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields.

RESULTS

Thirteen studies met the inclusion criteria and were included in the review. Ten peer social connectedness constructs and 18 measurement instruments were identified. Studies were predominantly focused on Special Olympics participants and unified activity formats. Participation in PA can increase social connectedness, but there is a lack of studies examining whether PA can also be increased by focusing on peer social connectedness in young people with ID.

CONCLUSIONS

Results show that peer social connectedness is recognised as relevant to researchers developing and testing PA programmes for young people with ID.

Physical Activity and Quality of Life among People with Intellectual Disabilities: The Role of Gender and the Practice Characteristics

Staying physically active is synonymous with good health and well-being, and its benefits on the health of people with intellectual disabilities (PWIDs) have been studied. However, there is a lack of information on how it can influence their quality of life (QoL). This study aimed to analyze the relationship between QoL and physical activity in PWIDs according to gender and the characteristics of the practiced activity. A questionnaire was administered to 380 PWIDs (mean age of 28.23 ± 12.53), 54.21% of which were men. The QoL dimensions and second-order factors were studied in relation to practicing physical activity, the practice type, the context, and gender. The results indicate that people who practiced any activity showed better QoL values. Those who engaged in a nonregulated physical activity had better values in self-determination, emotional well-being, social inclusion, and personal development, while those who did sports presented higher scores in interpersonal relationships and physical well-being. In addition, it also appears that the association between physical activity and the QoL dimensions is distinct in inclusive and specific contexts. In conclusion, physical activity is related to a better QoL, although the impact of the practice type and context differs for each QoL dimension.

The delivery of healthy lifestyle interventions for people with disability living in supported accommodation: a scoping review of intervention efficacy and consumer involvement

BACKGROUND

People with disability living in supported accommodation experience health disparities that may be partly attributed to sedentary lifestyle behaviors and poor dietary quality. Healthy lifestyle interventions have been suggested as a method of health promotion for this population; however, a synthesis of their efficacy has not yet been conducted.

OBJECTIVE

The primary aims were to (1) identify healthy lifestyle interventions delivered to people with disability living in supported accommodation and (2) examine their efficacy in supporting health and well-being. A secondary aim was to explore whether people with disability have been involved in the codesign of these interventions.

METHODS

A scoping review was conducted following the Joanna Briggs Institute's guidance for conducting scoping reviews, and six databases were searched from January 2011 to November 2021.

RESULTS

Thirty-two studies were included. Identified intervention types included training and education, exercise programs, and multicomponent interventions. A broad range of outcomes were examined; however, findings regarding efficacy were overall mixed and limited due to significant heterogeneity and the underreporting of consistently measured outcomes. The codesign of interventions in consultation with people with disability was underexplored.

CONCLUSIONS

Health promotion training for staff and tailored education for people with disability hold promise in creating a care environment that supports a healthy lifestyle. The paucity of interventions developed in consultation with people with disability is concerning and highlights the importance of meaningful co-design. The development of a theoretically informed intervention that is codesigned and addresses the broader social determinants that influence health behavior is recommended.

Promoting physical activity in everyday life of people with intellectual disabilities: An intervention overview

People with intellectual disabilities show significantly lower levels of physical activity than the general population in respect to all consequences for health. A positive effect of physical activity on health preservation has been proven, but interventions for physical activity in everyday life seem to be rare for people with intellectual disabilities. Based on a previously conducted scoping review the Template for Intervention Description and Replication (TIDieR) checklist was prepared. This article describes and compares physical activity interventions in everyday life for individuals with intellectual disabilities with the aim to of identifying successful strategies and areas for improvement. The 12 included interventions are heterogeneous, but commonalities and similarities can be identified. There are suggestions for successful strategies to implement physical activity interventions. However, much information could not be found. The promotion of healthier lifestyles is important to improve the overall health in this population.

Engaging and sustaining people with intellectual disabilities in physical activity: a narrative review of existing evidence

Background: People with intellectual disabilities (ID) experience many health and social inequalities. Increasing physical activity is a proven intervention to address such inequalities, yet the physical activity rates of this population are substantially lower than the general population. Aim: Research has been growing to understand why this is and how to intervene to increase the physical activity levels of people with ID. Method: Using a behavioural epidemiological framework, the research in this area from barriers and facilitators of physical activity to translational research testing interventions within natural settings is reviewed. Findings from a total of 14 reviews and eight empirical studies and protocols were included. Results: Whilst there are multiple investigations into what promotes or enhances physical activity for people with ID, findings from intervention studies show few successful outcomes. Gaps within the existing research are identified and recommendations about how intervention efficacy might be improved are provided to inform future research and practice. Conclusion: Findings from previous research on barriers and facilitators can be further capitalised on and intervention studies should be underpinned by better links to theory and more systemic approaches.

Review on the Formulation, Existing Problems, and Practical Effects of Fitness Exercise Prescriptions for People With Intellectual Disabilities

Compared with normal people, patients with intellectual disability have poor cardiopulmonary and muscle fitness levels, and their daily physical activity generally cannot reach the "guideline-recommended amount," which increases the risk of obesity and cardiovascular disease in this group. From the perspective of six elements of exercise prescription (frequency, intensity, time, form of exercise, amount of exercise, and progressive rate), this paper systematically reviews the current situation of the formulation and implementation of exercise prescription for patients with intellectual disabilities. The results show that the design idea of aerobic fitness exercise prescription for patients with intellectual impairment follows the six-element 5paradigm, but the insufficient recommended amount of each element is a common problem. In the design of muscle fitness exercise prescription, due to the differences of different exercise forms, the description of the six elements is very inconsistent. Although most prescription execution effects show that it is beneficial to improve cardiopulmonary and muscle fitness, there is a great debate on whether it is beneficial to improve body composition. People with intellectual disabilities are highly heterogeneous groups. In the initial stage of exercise intervention, the elements of exercise prescription need to be adjusted individually to obtain sustainable positive benefits.

Programs Using Stimulation-Regulating Technologies to Promote Physical Activity in People With Intellectual and Multiple Disabilities: Scoping Review

Background

People with intellectual and multiple disabilities tend to engage in very low levels of physical activity.

Objective

This review paper aims to provide a comprehensive picture of intervention programs using stimulation-regulating technologies to promote forms of physical activity in people with intellectual and multiple disabilities.

Methods

Following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) checklist, a scoping review was conducted to identify and provide a synthesis of eligible studies published in English between 2010 and 2021. Studies were identified by searching PubMed, Web of Science, PsycINFO, ERIC, and CINAHL as well as by using Google Scholar and manual searches. Studies were included if they involved individuals with intellectual or multiple disabilities, used stimulation-regulating technology systems to help participants engage in physical activity, and reported data on the impact of the intervention.

Results

A total of 42 studies met the inclusion criteria. These studies were divided into 2 groups based on whether they pursued the increase in physical activity through technology-aided delivery of brief periods of preferred stimulation contingent on specific responses or the use of video games (exergames) and related auditory and visual stimulation. Subsequently, a narrative synthesis of the studies was provided.

Conclusions

The evidence reported by the 2 groups of studies is encouraging. However, further research is needed to compare the overall applicability and impact of the intervention strategies proposed by these groups of studies.

Effects of physical activity on behaviour and emotional problems, mental health and psychosocial well-being in children and adolescents with intellectual disability: A systematic review

BACKGROUND

This systematic review aimed to explore the effects of sport and physical activity on behaviour and emotional problems, mental health and psychosocial well-being of children and adolescents with intellectual disability.

METHOD

Five databases were searched systematically (ERIC, MEDLINE, PsycINFO, SportDISCUS and SCOPUS), up to 28 February 2021. Thirty-two studies met criteria for inclusion.

RESULTS

Studies in this review included case studies (n = 15), treatment trials (n = 14), cross sectional studies (n = 2) and a cohort study (n = 1). Evidence was positive, though high risk of bias in treatment trials (7 of 14 rated high) meant generalisability of results was limited.

CONCLUSIONS

The available evidence suggests a positive relationship between physical activity and improved behaviour and emotional problems, mental health and psychosocial well-being; however, more robust randomised controlled trials are required to confirm this.

Promoting physical activity participation and nutrition education through a telehealth intervention for children on the autism spectrum and their caregivers

There is growing empirical support which suggests children on the autism spectrum, as well as their caregivers experience significant health disparities. The global COVID-19 pandemic has only magnified the need to address health among vulnerable populations. While there has been a growing trend in the delivery of telehealth interventions, the delivery of such methods for children on the autism spectrum, and their caregivers remains relatively under examined. The primary goal of PLANE (Physical Literacy And Nutrition Education) is to promote positive trajectories of health for children on the autism spectrum and their primary caregivers through the delivery of a telehealth physical activity and nutrition education program. The study is a pre-experimental analysis of PLANE across 12 months. All activities will be delivered virtually through weekly synchronous and asynchronous programming. A total of 180 participants will be enrolled in this intervention, including children on the autism spectrum and caregivers. Each week a new physical activity skill along with opportunities for recipe assembly will be delivered remotely. Supplemental material will be disseminated online including; step by step directions outlining behavioral skill methodology, opportunities for additional skill practice, and reading material that support weekly topics. Study outcomes will be examined in the parent-child dyad and include rates of overweight/obesity, physical activity, nutrition and quality of life. Finally, feasibility of the telehealth intervention will also be measured. Justification for the conceptualization and delivery of PLANE is well warranted, and PLANE represents a promising intervention which is scalable, sustainable, and replicable.

Aquatic exercise for people with intellectual disabilities: findings from a systematic review

Background: There is a need for promoting exercise practice among people with intellectual disabilities (ID). Aquatic exercise (AE) could be a viable option in this regard. Objective: To identify and critically analyze the best available evidence concerning the effects of AE in the physical and mental health of people with ID. Methods: A systematic review of randomized controlled trials (RCTs) and comparative studies was performed after searching within several databases up to March 2021. Results: A total of 4 RCTs and 3 comparative studies were found. Their methodological quality ranged from high to low. Aquatic interventions had positive effects on cardiorespiratory, muscular fitness and balance. Mixed effects were seen on parameters related to obesity and cognition. Scant information regarding feasibility and intervention fidelity was provided. In general, interventions details were not discussed in deep. Conclusion: Preliminary evidence shows that aquatic exercise can be prescribed to people with ID in order to improve their physical health. The impact of aquatic exercise on motor skills, cognitive function and mental health remains unclear. Further research on this topic should provide a detailed description of the interventions carried out, including information on the feasibility and intervention fidelity.

Physical activity promotion and adults with intellectual disabilities: A neglected area

BACKGROUND

The objective was to review physical activity (PA) promotion interventions among individuals with intellectual disability and provide recommendations for increasing PA.

METHODS

A systematic mapping review was conducted in which physical activity intervention studies for adults with a disability were identified, selected, and appraised. Data were extracted regarding the study design, results, and authors' recommendations. Data were analyzed using a social-ecological framework.

RESULTS

A comprehensive search of the peer reviewed literature yielded 5 studies (3 quantitative, 1 mixed methods, and 1 pre-post delayed). Studies used physical activity promotion strategies at the intrapersonal, interpersonal, organizational, community, and policy levels have been used to date.

CONCLUSIONS

Recommendations are presented for researchers and practitioners seeking to increase the level of PA of adults with intellectual disability.

The impact of badminton lessons on health and wellness of young adults with intellectual disabilities: a pilot study

Background: Physical activity has been proposed as a context to foster the healthy development of individuals and reduce the risk of many chronic problems. This study evaluates the impact of badminton lessons on health and wellness in young adults with intellectual disabilities (ID). Methods: Eighteen participants with ID (14 males and 4 females, aged 19-26) and with little or no experience in badminton were assigned to an exercise group and a control group. The curriculum selected was Shuttle Time Starter Lessons. The exercise group practiced for 50 min each session, twice a week for 10 lessons with peers, while the control group maintained a regular life schedule. Physiological measures, motor performance, Special Olympics Individual Badminton Skills Assessment; and psychological measures were conducted before and after the program. A Wilcoxon signed-rank test was conducted to compare pre- and post-tests in each group. Results: The significantly reduced resting heart rate, longer walking distances in the 6-minute walk test, and better performance in badminton skills were evident in the exercise group. Further, a significantly increased left frontal alpha asymmetry was seen in the exercise group with participants expressing positive effects after the inclusive badminton program. Finally, resting EEG frontal asymmetry seemed to be reflective of emotion in persons with ID. Conclusions: Shuttle Time Badminton Lessons could be feasible for adults with ID. School teachers and coaches may adapt it to improve health and wellness and acquire badminton skills in adults with ID. In addition, the inclusive environment can motivate their participation.

Participation in sport and physical activity in adults with intellectual disabilities

BACKGROUND

People with intellectual disability face a number of barriers to participation in physical activity. This paper aimed to determine rates of sport and physical activity participation in an Australian sample of adults with intellectual disability, compared with rates of participation in the general Australian population. A secondary aim was to investigate factors that may contribute to participation of adults with intellectual disability.

METHOD

Participants were part of the Australian Child to Adult Development (ACAD) study, consisting of a community sample with intellectual disability (n = 305), groups of adults with autism (n = 94), Down syndrome (n = 64), fragile X syndrome (n = 52), Williams syndrome (n = 45), and Prader-Willi syndrome (n = 30). Participation in sport/physical activity was reported over the past 3 months. Rates of participation were reported for adults with intellectual disability and compared with rates in a general Australian population sample. The relationship between participation in physical activity and age, degree of intellectual disability, physical mobility, living situation, socio-economic disadvantage, and behaviour and emotional problems were also conducted.

RESULTS

Participants in the ACAD community sample with intellectual disability participated in sport/physical activity at lower rates than the general Australian population (42% compared with 71%). Having no physical mobility impairment was significantly associated with higher rates of participation. Those with Down syndrome participated in sport/physical activity at higher rates than the community sample with intellectual disability, while no difference in sport/physical activity participation was observed in the groups with autism or other syndromes.

CONCLUSION

Australian adults with intellectual disability participate in sport and physical activity at lower rates than the general population. Having a physical mobility impairment was associated with lower rates of participation. However, people living in supported accommodation were more likely to participate than those in other living situations. Having Down syndrome was associated with a higher participation rate than the community sample.

Body Expression-Based Intervention Programs for Persons with Intellectual Disabilities: A Systematic Review

The benefits of physical exercise on human health are widely known. However, the level of physical activity in the majority of the population is considered insufficient. People with intellectual disabilities (ID), in particular, show this lack of physical activity to a greater extent. It has been noted that the promotion of activities focused on corporal expression (CE) stimulates the motivation to carry out physical exercise in this population group. The aim of this study was to carry out a systematic review of the last ten years of CE programs carried out in people with ID. The criteria established in the PRISMA statement were followed in the literature search. The databases consulted were Scopus, Web of Science, Pubmed, PsycInfo and Elton B. Stephens Company (EBSCO). Eight exclusion criteria were established for the selection of articles. For the analysis of the selected research, three quality criteria for interventions were established. Subsequently, a summary table with the characteristics of each study was made. In conclusion, it can be stated that CE programs in people with ID report benefits at both physical and psychosocial levels. It is necessary to extend this approach for the promotion of healthy physical activity that advocates social inclusion.

Predicting the rate of oxygen uptake from step counts using ActiGraph waist-worn accelerometers in adults with Down syndrome

BACKGROUND

Step rate predicts ambulatory intensity as reflected in the rate of oxygen uptake (VO₂ ) - a measure of energy expenditure. Whether step rate as measured by an accelerometer predicts VO₂ in adults with Down syndrome (DS) is unknown. We examined whether step rate predicts VO₂ in adults with and without DS. We also developed an equation for predicting VO₂ and examined its accuracy.

METHOD

Sixteen adults with DS (6 women and 10 men; age 31 ± 15 years) and 19 adults without DS (9 women and 10 men; age 25 ± 6 years) performed standing and walking at their preferred speed, 0.8 and 1.4 m·s^-1 . We measured VO₂ with a portable spirometer and step rate with a triaxial accelerometer (wGT3X-BT; ActiGraph) on the non-dominant hip, using the low-frequency extension filter. We ran multilevel regression for predicting VO₂ from linear and quadratic terms for step rate, group (1 = DS; 0 = non-DS), body mass, height, body mass index (BMI), leg length and sex. We estimated VO₂ with the resultant equation and calculated the equation's absolute per cent error, which we compared between groups.

RESULTS

VO₂ was higher in persons with than without DS only at the fast walking speed (P = 0.018). DS did not predict VO₂ . Step rate, step rate squared and BMI were significant predictors of VO₂ (P < 0.001; R²  = 0.80). Absolute error across walking speeds was 13.5-18.8% and 11.7-13.4% for adults with and without DS, respectively, and did not differ between groups or speeds.

CONCLUSIONS

Step rate, step rate squared and BMI predict VO₂ in adults with and without DS. Prediction error does not differ between groups.

Construct validity of the Actiwatch-2 for assessing movement in people with profound intellectual and multiple disabilities

Background

Valid measures to assess either small or assisted performed movements of people with profound intellectual and multiple disabilities (PIMD) are required. We analysed the construct validity of the Actiwatch‐2 to assess movement in people with PIMD.

Method

Twenty‐two persons with PIMD were video recorded while wearing an Actiwatch‐2. We used 15s‐partial‐interval recording to record upper body movement, body position and activity situation. Multilevel analyses were used to evaluate if the Actiwatch‐2, based on produced counts, could detect changes in these factors.

Results

The presence versus absence of upper body movement and an activity situation in which participants were involved versus not involved resulted in significantly higher counts, with a large variety in predicted counts between participants. No relationship between body position and counts was found.

Conclusions

The Actiwatch‐2 seems able to assess obvious upper body movement in people with PIMD, and whether there is involvement in an activity situation.

Physical Activity and Sedentary Behavior Among U.S. Children With and Without Down Syndrome: The National Survey of Children's Health

It is unclear whether children with Down syndrome have differing physical activity and sedentary behavior levels compared to typical children. This study addressed this evidence gap in a national sample. Physical activity/sedentary behavior were ascertained by parental report. Findings highlighted that children with Down syndrome were less likely to engage in regular physical activity compared to typical children and had the lowest likelihood of regular physical activity among all subgroups with developmental disabilities/special healthcare needs. Children with Down syndrome were also more likely to watch high volumes of television compared to typical children, although this was nonsignificant upon adjustment for general health. It was concluded that children with Down syndrome are in urgent need for interventions/programs that promote physical activity.
