Healthy lifestyles for adults with intellectual disability: knowledge, barriers, and facilitators

Cancer risks related to intellectual disabilities: A systematic review

BACKGROUND

People with intellectual disabilities (ID) face barriers in cancer care contributing to poorer oncological outcomes. Yet, understanding cancer risks in the ID population remains incomplete.

AIM

To provide an overview of cancer incidence and cancer risk assessments in the entire ID population as well as within ID-related disorders.

METHODS

This systematic review examined cancer risk in the entire ID population and ID-related disorders. We systematically searched PubMed (MEDLINE) and EMBASE for literature from January 1, 2000 to July 15, 2022 using a search strategy combining terms related to cancer, incidence, and ID.

RESULTS

We found 55 articles assessing cancer risks in the ID population at large groups or in subgroups with ID-related syndromes, indicating that overall cancer risk in the ID population is lower or comparable with that of the general population, while specific disorders (e.g., Down's syndrome) and certain genetic mutations may elevate the risk for particular cancers.

DISCUSSION

The heterogeneity within the ID population challenges precise cancer risk assessment at the population level. Nonetheless, within certain subgroups, such as individuals with specific ID-related disorders or certain genetic mutations, a more distinct pattern of varying cancer risks compared to the general population becomes apparent.

CONCLUSION

More awareness, and personalized approach in cancer screening within the ID population is necessary.

Long-term outdoor recreation program for adults with intellectual disabilities: Feasibility and effects

BACKGROUND

While people with intellectual disabilities tend to refrain from physical activity, outdoor physical activity programs increase motivation to engage in physical activity.

METHOD

Eighty adults with intellectual disabilities participated in a 12-month outdoor physical activity program. Attendance was used to assess feasibility. Aerobic capacity (6-min walk test), lower extremity endurance (30-s chair stand), and mobility (timed up and go) were assessed at three-time points: before, during, and after the program. Six interviews were also conducted with six staff members and participants.

RESULTS

The physical activity program was feasible, with all six groups completing the year-long activity. The six-minute walk and timed-up-and-go tests improved significantly. The qualitative analysis indicates the program's strengths (instructors' qualities and programs' social component) and weaknesses (dependency on weather and bureaucracy).

CONCLUSION

Among adults with intellectual disabilities, a long-term outdoor physical activity program is feasible as a means for increasing aerobic capacity and improving mobility ability.

Factors Related to Physical Activity in Adults With Intellectual Disabilities in Group Home Settings: A Systematic Literature Review

This systematic review of literature aimed to synthesize the multilevel factors related to physical activity (PA) among adults (age 18-65) with intellectual disability living in group homes. Keyword searches were used to identify articles from electronic databases, resulting in the inclusion of 10 articles for full-text review. Data were extracted relating to study and sample characteristics and study findings. Methodological quality of the studies was also evaluated. Factors related to PA in group homes were identified at all levels of the social-ecological model. Intrapersonal factors (e.g., health and functional status, attitude to PA), interpersonal factors (e.g., staff attitude, encouragement for PA, and coparticipation in PA), and organizational factors (e.g., program offerings, staff education, and staff-client ratios) were prominent findings in the reviewed studies. The findings support a social-ecological approach for PA promotion in group homes that target intrapersonal, interpersonal, and organizational factors.

'Get Healthy!' physical activity and healthy eating intervention for adults with intellectual disability: results from the feasibility pilot

BACKGROUND

People with intellectual disabilities (ID) experience high rates of lifestyle related morbidities, in part due to lack of access to tailored health promotion programmes. This study aimed to assess the feasibility and preliminary efficacy of a tailored healthy lifestyle intervention, Get Healthy!

METHODS

Get Healthy! is a 12-week physical activity and healthy eating programme designed to address lifestyle-related risks for adults with mild-moderate ID. The feasibility pilot was designed to assess subjective participant experience and programme feasibility across: recruitment and screening, retention, session attendance and engagement, adverse events, and practicality and reliability of outcome procedures. Exploratory programme efficacy was assessed across the following measures: anthropometry (body mass index, weight, waist circumference), cardiovascular fitness, physical strength, dietary intake, healthy literacy, and quality of life.

RESULTS

Six participants with moderate ID and two carer participants completed the feasibility trial, representing a 100% retention rate. Qualitative data indicated the programme was well received. Participants with ID attended 75% of sessions offered and displayed a high level of engagement in sessions attended (91% mean engagement score). While most data collection procedures were feasible to implement, several measures were either not feasible for our participants, or required a higher level of support to implement than was provided in the existing trial protocol. Participants with ID displayed decreases in mean waist circumference between baseline and endpoint (95% CI: - 3.20, - 0.17 cm) and some improvements in measures of cardiovascular fitness and physical strength. No changes in weight, body mass index, or objectively measured knowledge of nutrition and exercise or quality of life were detected from baseline to programme endpoint. Dietary intake results were mixed.

DISCUSSION

The Get Healthy! programme was feasible to implement and well received by participants with moderate ID and their carers. Exploratory efficacy data indicates the programme has potential to positively impact important cardiometabolic risk factors such as waist circumference, cardiovascular fitness, and physical strength. Several of the proposed data collection instruments will require modification or replacement prior to use in a sufficiently powered efficacy trial.

Barriers and enablers to the implementation of healthy lifestyle interventions for people with disability living in supported accommodation: A systematic review using the consolidated framework for implementation research

BACKGROUND

People with disability living in supported accommodation often experience significant health disparities, despite the availability of additional support. Healthy lifestyle interventions have been identified as one key health promotion strategy. Implementation science offers an opportunity to explore the factors that influence the efficacy and sustainability of these interventions, yet its application in this context has been underutilized.

OBJECTIVE

This systematic review synthesized the barriers and enablers to the implementation of healthy lifestyle interventions delivered to people with disability living in supported accommodation settings.

METHODS

A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A search for relevant literature published between January 2011 and November 2021 was conducted across six databases. The findings of included studies were coded and analyzed according to the domains and constructs of the Consolidated Framework for Implementation Research (CFIR) via deductive content analysis.

RESULTS

Five studies were included, and their findings were mapped to 21 out of 38 constructs under the CFIR. Interventions from each study delivered health promotion education and training to staff and/or people with disability. The most prominent determinants that influenced implementation success included an intervention's relevance and its flexibility to adapt to the needs of people with disability, alongside organizational resourcing, and stakeholder endorsement in supporting implementation.

CONCLUSIONS

The CFIR provided a systematic approach to explore the implementation of healthy lifestyle interventions. However, further research that is grounded in and guided by implementation science theories is warranted. Despite the scarcity of literature, several compelling, yet preliminary recommendations were drawn from the findings.

Exploration of diet, physical activity, health knowledge and the cardiometabolic profile of young adults with intellectual disability

BACKGROUND

Young adults with intellectual disability (ID) are experiencing early mortality, and it is suggested that they are living with undiagnosed cardiovascular and metabolic risk factors (hereafter referred to as cardiometabolic).

METHODS

We investigated the association between modifiable risk factors and cardiometabolic health profile in adults with ID aged 18-45 years through clinical evaluation of traditional cardiometabolic parameters, and assessment of physical activity levels, diet and associated health knowledge.

RESULTS

We found that young adults with ID have an increased obesity (mean body mass index; ID group: 32.9 ± 8.6 vs. control group: 26.2 ± 5.5, P = 0.001), are engaging in less physical activity than the age-matched general population (total activity minutes per week; ID group: 172.2 ± 148.9 vs. control group: 416.4 ± 277.1, P < 0.001), and overall have unhealthier diets. Additionally, knowledge about nutrition and physical activity appears to be an important predictor of cardiometabolic risk in this population. If young people with ID are to improve their cardiometabolic health to reduce morbidity and early mortality, we need to further explore how to consistently apply health messaging to get lasting behavioural change in this population.

Determining the need for a breast cancer awareness educational intervention for women with mild/moderate levels of intellectual disability: A qualitative descriptive study

OBJECTIVE

Following a review of the existing body of literature, this study aimed to explore the need for a breast cancer awareness intervention specifically targeted at women with mild/moderate levels of intellectual disability (ID) and provide perspectives on the preferred processes and content underpinning an intervention.

METHODS

A qualitative, descriptive design using semi-structured, individual (n = 5) and focus group (n = 5) interviews were used to engage with a non-probability, purposive sample of key stakeholders (n = 25) including women with mild/moderate levels of ID, caregivers and healthcare professionals. Data were analysed using qualitative content analysis.

RESULTS

Findings highlighted that an educational intervention should focus on breast awareness as opposed to breast cancer awareness. Additionally, findings identified that a combined breast awareness and healthy living intervention could be effective. However, the intervention needs to have a multimodal, hands-on, person-centred approach to learning which is underpinned by theory. Furthermore, integrating the caregivers and healthcare professionals into the intervention is recommended.

CONCLUSION

Findings from this study provide a foundation for developing and implementing a theoretically underpinned, multimodal, breast awareness and healthy living educational intervention for women with mild/moderate levels of ID.

Gaining actionable knowledge to improve local health-promoting capacities in long-term care support settings for people with intellectual disabilities

OBJECTIVE

People with intellectual disabilities (ID) are largely dependent on their environment to live healthily and, in this, ID-support organizations play a vital role. An environmental asset mapping tool for ID-support settings has been developed. This study aims to provide insight into whether or not the tool can provide a comprehensive view on assets in the system and actionable knowledge to improve health-promoting capacities in ID-support settings.

METHODS

Fifty-seven users from four setting completed the tool on availability, user satisfaction, and dreams regarding social, physical, organizational, and financial assets.

RESULTS

The findings provide a comprehensive view of available assets. Together with user satisfaction and dreams for improvements, they provide actionable knowledge for improving the health-promoting capacities of the settings, including: (1) how use of available assets can be improved, (2) the type of assets that should be enriched, and (3) the assets that can be added to the system.

CONCLUSION

The asset mapping tool provides a comprehensive view on assets in the system and actionable knowledge to improve health-promoting capacities in ID-support settings.

PRACTICE IMPLICATIONS

ID-support organizations can use the tool to generate actionable bottom-up knowledge for priority setting and implementing interventions to improve their health-promoting capacities.

A Systematic Review of Health Promotion Programs to Improve Nutrition for People with Intellectual Disability

PURPOSE OF REVIEW

To investigate the type and effectiveness of health promotion programs designed to improve nutrition for people with intellectual disability. This review also sought to highlight gaps in the evidence by mapping interventions to the socio-ecological model.

RECENT FINDINGS

To date, reviews on health promotion programs for people with intellectual disability have focused on individualised weight management interventions and behaviour change techniques. No reviews have focused solely on nutrition or considered a broader range of interventions and policies targeted beyond the individual. This review found that health promotion interventions to date were predominantly at the individual level of the socio-ecological model and of varying effectiveness. Of the non-individually focused interventions, those targeting the physical environment or considering multiple socio-ecological levels achieved the greatest improvements in nutrition outcomes. Nutrition and obesity prevention research and policy need to include intellectual disability as part of equity considerations, while intellectual disability policy needs to consider the broader food environment.

Cancer risk in individuals with intellectual disability in Sweden: A population-based cohort study

BACKGROUND

A knowledge gap exists about the risk of cancer in individuals with intellectual disability (ID). The primary aim of this study was to estimate the cancer risk among individuals with ID compared to individuals without ID.

METHODS AND FINDINGS

We conducted a population-based cohort study of all children live-born in Sweden between 1974 and 2013 and whose mothers were born in a Nordic country. All individuals were followed from birth until cancer diagnosis, emigration, death, or 31 December 2016 (up to age 43 years), whichever came first. Incident cancers were identified from the Swedish Cancer Register. We fitted Cox regression models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) as measures of cancer risk in relation to ID after adjusting for several potential confounders. We analyzed ID by severity, as well as idiopathic ID and syndromic ID separately. We performed a sibling comparison to investigate familial confounding. The study cohort included a total of 3,531,305 individuals, including 27,956 (0.8%) individuals diagnosed with ID. Compared with the reference group (individuals without ID and without a full sibling with ID), individuals with ID were in general more likely to be male. The median follow-up time was 8.9 and 23.0 years for individuals with ID and individuals without ID, respectively. A total of 188 cancer cases were identified among individuals with ID (incidence rate [IR], 62 per 1,000 person-years), and 24,960 among individuals in the reference group (IR, 31 per 1,000 person-years). A statistically significantly increased risk was observed for any cancer (HR 1.57, 95% CI 1.35-1.82; P < 0.001), as well as for several cancer types, including cancers of the esophagus (HR 28.4, 95% CI 6.2-130.6; P < 0.001), stomach (HR 6.1, 95% CI 1.5-24.9; P = 0.013), small intestine (HR 12.0, 95% CI 2.9-50.1; P < 0.001), colon (HR 2.0, 95% CI 1.0-4.1; P = 0.045), pancreas (HR 6.0, 95% CI 1.5-24.8; P = 0.013), uterus (HR 11.7, 95% CI 1.5-90.7; P = 0.019), kidney (HR 4.4, 95% CI 2.0-9.8; P < 0.001), central nervous system (HR 2.7, 95% CI 2.0-3.7; P < 0.001), and other or unspecified sites (HR 4.8, 95% CI 1.8-12.9; P = 0.002), as well as acute lymphoid leukemia (HR 2.4, 95% CI 1.3-4.4; P = 0.003) and acute myeloid leukemia (HR 3.0, 95% CI 1.4-6.4; P = 0.004). Cancer risk was not modified by ID severity or sex but was higher for syndromic ID. The sibling comparison showed little support for familial confounding. The main study limitations were the limited statistical power for the analyses of specific cancer types, and the potential for underestimation of the studied associations (e.g., due to potential underdetection or delayed diagnosis of cancer among individuals with ID).

CONCLUSIONS

In this study, we found that individuals with ID showed an increased risk of any cancer, as well as of several specific cancer types. These findings suggest that extended surveillance and early intervention for cancer among individuals with ID are warranted.

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.

Towards healthy settings for people with intellectual disabilities

People with intellectual disabilities (ID) depend on their environment for support to live healthily. The characteristics of healthy settings for people with ID are unknown. This study aims to conceptualize healthy settings for people with ID by conducting an international and multidisciplinary concept mapping study. As theoretical framework the settings approach, an ecological model with a whole system focus toward health promotion, was used. The integrative mixed-methods approach of this study involved concept mapping with researchers specialized in healthcare for people with ID and researchers specialized in healthy settings. The 41 participants generated statements that were later sorted and rated. Findings encompass 13 clusters relating to the social environment, the physical environment and societal preconditions. Specific factors of healthy settings for people with ID include: (i) universal design of the physical environment, (ii) the role of care professionals in the social environment to empower people with ID, (iii) possibilities for care providers to contribute to a health-promoting setting and (iv) preconditions that allow people to engage in society. These factors can be used in strategies to apply the approach in practice and give directions to put in place policies on developing enabling environments and decreasing health inequities.

"I sit all of the time": Health-related time-use among adults with intellectual disabilities

BACKGROUND

Adults diagnosed with intellectual disabilities (ID) are more likely to have cardiometabolic risk factors, including low physical activity (PA), high sedentary behavior (SB), and poor sleep. While these behaviors have typically been studied in isolation, emerging frameworks propose a more integrated approach to the study of these behaviors, asserting that the relative proportion of time spent in each of the health-related time-use behaviors (i.e. PA, SB and sleep) across the 24 -h period is a more powerful determinant of the incidence and progression of disease. This approach has yet to be considered for adults with ID. The purpose of this study was to explore how adults with ID and their formal caregivers (i.e. employed caregivers) perceived their health-related time-use, including the factors that influence their time-use.

METHOD

Five focus groups were conducted with twelve adults with ID and ten formal-caregivers. Consistent with an interpretive paradigm, this study employed an interpretative phenomenological analysis (IPA) methodology.

RESULTS

Three interrelated themes were identified: (1) Caregivers as gatekeepers to healthy time-use; (2) Places to move; and (3) Daily movement. The themes captured the participants' perspectives of interpersonal and environmental factors that influence health-related time-use, and how these factors were common to engagement in at least on health-related time-use behavior.

CONCLUSIONS

Interpersonal factors, including caregivers support and modeling-behaviors, and community factors, in the form of local, accessible, affordable spaces to be active, were identified as the most pertinent factors in determining PA, SB and sleep behaviors. Moreover, adults with ID and caregivers perceived health-related time-use behaviors to be interrelated. Further investigation in this area will ultimately inform the development of pilot interventions that support caregivers as gatekeepers and provide access to health-promoting environments to engage adults with ID in healthy levels of PA, SB, and sleep.

How can care settings for people with intellectual disabilities embed health promotion?

BACKGROUND

People with intellectual disabilities (ID) depend on their environment to live healthily. Asset-based health promotion enhances a settings' health-promoting capacity starting with identifying protective or promotive factors that sustain health.

METHOD

This inclusive mixed-methods study used group sessions to generate and rank ideas on assets supporting healthy nutrition and physical activity in Dutch intellectual disability care settings. Participants included people with moderate intellectual disabilities and family and care professionals of people with severe/profound intellectual disabilities.

RESULTS

Fifty-one participants identified 185 assets in group sessions. They include the following: (i) the social network and ways "people" can support, (ii) assets in/around "places," and person-environment fit, and (iii) "preconditions": health care, prevention, budget, and policy.

CONCLUSION

This inclusive research provides a user perspective on assets in the living environment supporting healthy living. This gives insight in contextual factors needed for development and sustainable embedment of health promotion in the systems of intellectual disability support settings.

Measuring Environmental Barriers: Validation and Cultural Adaptation of the Italian Version of the Craig Hospital Inventory of Environmental Factors (CHIEF) Scale

The study aimed to validate an Italian translation of the Craig Hospital Inventory of Environmental Factors (CHIEF) environmental assessment tool. The CHIEF scale was administered throughout Italy to 506 individuals who did not present with serious and/or disabling diseases. The results show an excellent interrelation between CHIEF scale items and the subscales. Furthermore, our analysis demonstrates that following repeated administration to the same participants, the instrument maintains excellent stability of each subscale for the frequency, magnitude, and impact of the barriers. This study demonstrates that the Italian version of the CHIEF scale is reliable for measuring environmental barriers. The findings show that the scale is suitable for the clinical and research fields to broaden our knowledge about this relevant yet poorly studied field.

Integrating Health Promotion in the Everyday Life of People With Intellectual Disability-The Extent to Which Current Initiatives Take Context Into Account

Taking the dynamics of everyday life into account is important for health behavior change. Surveys were conducted to gain insight into available health promoting physical activity and nutrition initiatives in the everyday life of people with intellectual disability (ID). Researchers considered characteristics of the initiatives and the attention they give to resources and hindering factors of healthy living for people with ID. The 47 initiatives mostly focused on physical activity and consisted of regularly organized, stand-alone activities. Care professionals, rather than health professionals, were involved. Organizational resources and hindering factors received relatively little attention. Health promotion for people with ID could benefit from incorporating health behavior into routines of daily living, focusing more attention on organizational resources, and improving the collaboration between health professionals and care professionals.

Diabetes in adults with intellectual disability: prevalence and associated demographic, lifestyle, independence and health factors

BACKGROUND

As people with intellectual disabilities (ID) are now living longer, they are more at risk of developing non-communicable diseases, including type 2 diabetes mellitus. However, understanding of factors associated with diabetes for targeted management and prevention strategies is limited. This study aimed to investigate prevalence of diabetes in adults (aged ≥18 years) with ID and its relationship with demographic, lifestyle, independence and health factors.

METHOD

This was a cross-sectional analysis of interview data from 1091 adults with ID from the Leicestershire Learning Disability Register from 1 January 2010 to 31 December 2016. Logistic regression models were used to identify factors associated with diabetes in the study population.

RESULTS

The study population did not have healthy lifestyles: just under half reported having lower physical activity levels than people without ID of a similar age; one-quarter consumed fizzy drinks daily; and 20% consumed five or more fruit and/or vegetables per day. Prevalence of carer/self-reported diabetes was 7.3% (95% confidence interval 5.9-9.0). After adjustment, diabetes was positively associated with South Asian ethnicity (P = 0.03) and older age groups (P < 0.001). Diabetes was less common in people living with family members (P = 0.02). We did not find a relationship between any of the lifestyle, independence and health factors investigated.

CONCLUSIONS

A significant proportion of people with ID are living with diabetes. Diabetes management and prevention strategies should be tailored to individuals' complex needs and include consideration of lifestyle choices. Such strategies may want to focus on adults of South Asian ethnicity and people living in residential homes where prevalence appears to be higher.

Managing with Learning Disability and Diabetes: OK-Diabetes - a case-finding study and feasibility randomised controlled trial

BACKGROUND

Obesity and type 2 diabetes are common in adults with a learning disability. It is not known if the principles of self-management can be applied in this population.

OBJECTIVES

To develop and evaluate a case-finding method and undertake an observational study of adults with a learning disability and type 2 diabetes, to develop a standardised supported self-management (SSM) intervention and measure of adherence and to undertake a feasibility randomised controlled trial (RCT) of SSM versus treatment as usual (TAU).

DESIGN

Observational study and an individually randomised feasibility RCT.

SETTING

Three cities in West Yorkshire, UK.

PARTICIPANTS

In the observational study: adults aged > 18 years with a mild or moderate learning disability, who have type 2 diabetes that is not being treated with insulin and who are living in the community. Participants had mental capacity to consent to research and to the intervention. In the RCT participants had glycated haemoglobin (HbA_1c) levels of > 6.5% (48 mmol/mol), a body mass index (BMI) of > 25 kg/m² or self-reported physical activity below national guideline levels.

INTERVENTIONS

Standardised SSM. TAU supported by an easy-read booklet.

MAIN OUTCOME MEASURES

(1) The number of eligible participants identified and sources of referral; (2) current living and support arrangements; (3) current health state, including level of HbA_1c, BMI and waist circumference, blood pressure and lipids; (4) mood, preferences for change; (5) recruitment and retention in RCT; (6) implementation and adherence to the intervention; (7) completeness of data collection and values for candidate primary outcomes; and (8) qualitative data on participant experience of the research process and intervention.

RESULTS

In the observational study we identified 147 eligible consenting participants. The mean age was 54.4 years. In total, 130 out of 147 (88%) named a key supporter, with 113 supporters (77%) being involved in diabetes management. The mean HbA_1c level was 54.5 mmol/mol [standard deviation (SD) 14.8 mmol/mol; 7.1%, SD 1.4%]. The BMI of 65% of participants was > 30 kg/m² and of 21% was > 40 kg/m². Many participants reported low mood, dissatisfaction with lifestyle and diabetes management and an interest in change. Non-response rates were high (45/147, 31%) for medical data requested from the primary care team. In the RCT, 82 participants were randomised. The mean baseline HbA_1c level was 56 mmol/mol (SD 16.5 mmol/mol; 7.3%, SD 1.5%) and the mean BMI was 34 kg/m² (SD 7.6 kg/m²). All SSM sessions were completed by 35 out of 41 participants. The adherence measure was obtained in 37 out of 41 participants. The follow-up HbA_1c level and BMI was obtained for 75 out of 82 (91%) and 77 out of 82 (94%) participants, respectively. Most participants reported a positive experience of the intervention. A low response rate and difficulty understanding the EuroQol-5 Dimensions were challenges in obtaining data for an economic analysis.

LIMITATIONS

We recruited from only 60% of eligible general practices, and 90% of participants were on a general practice learning disability register, which meant that we did not recruit many participants from the wider population with milder learning disability.

CONCLUSIONS

A definitive RCT is feasible and would need to recruit 194 participants per arm. The main barrier is the resource-intensive nature of recruitment. Future research is needed into the effectiveness of obesity treatments in this population, particularly estimating the longer-term outcomes that are important for health benefit. Research is also needed into improving ways of assessing quality of life in adults with a learning disability.

Examining determinants of lifestyle interventions targeting persons with intellectual disabilities supported by healthcare organizations: Usability of the Measurement Instrument for Determinants of Innovations

BACKGROUND

Due to complex processes of implementation of innovations aimed at persons with intellectual disabilities in healthcare organizations, lifestyle interventions are not used as intended or not used at all. In order to provide insight into determinants influencing this implementation, this study aims to ascertain if the Measurement Instrument for Determinants of Innovations (MIDI) is useful for objectively evaluating implementation.

METHOD

With semi-structured interviews, data concerning determinants of implementation of lifestyle interventions were aggregated. These data were compared to the determinants questioned in the MIDI. Adaptations to the MIDI were made in consultation with the author of the MIDI.

RESULTS

All determinants of the MIDI, except for that concerning legislation and regulations, were represented in the interview data. Determinants not represented in the MIDI were the level of intellectual disabilities, suitability of materials and physical environment, multi-levelness of interventions and several persons who could be involved in the intervention, such as direct support persons (DSPs), a therapist or family, and the communication between these involved persons.

CONCLUSION

The present authors suggested making adjustments to existing questions of the MIDI in order to improve usability for deployment in organizations that provide care to persons with intellectual disabilities. The adjustments need to be tested with other interventions.

Enhancing Engagement With Socially Disadvantaged Older People in Organized Physical Activity Programs

BACKGROUND AND OBJECTIVES

Participation in physical activity (PA) is low among older adults in developed nations and even lower among several socially disadvantaged groups. This study aimed to identify the actions that can be taken in the promotion, design, and implementation of organized PA programs to improve engagement with socially disadvantaged and underrepresented older people. Research design and methods: Semistructured interviews were conducted with 30 community service providers and 5 focus groups with 42 older participants in existing PA programs. Data were analyzed thematically, and the PRECEDE-PROCEED model for program planning was used to broadly categorize themes. Results: Helpful strategies for addressing predisposing factors such as social anxiety and lack of confidence included user-centered program design and sensitive, informative messaging and promotion. Key enabling strategies were transport assistance and minimizing fees. Facilitating gentle entry to groups and fostering inclusion and safety were identified as valuable reinforcing strategies. Providers regarded organizational networks as beneficial for facilitating referral and addressing resource constraints. Discussion and implications: A multifactorial approach addressing a range of predisposing, reinforcing, and enabling factors is likely to be necessary to enhance engagement in organized PA by socially disadvantaged and underrepresented older people. Key factors relate to creating a positive sociocultural environment, identifying activities of interest, and enhancing ease of access.

'Get Healthy!' A physical activity and nutrition program for older adults with intellectual disability: pilot study protocol

BACKGROUND

Older adults with intellectual disability have high rates of lifestyle-related illness yet remain poorly engaged in physical activity and nutrition interventions. There is a need to clarify what types of healthy lifestyle interventions are feasible and effective to implement in this population and how outcome measures can best be tracked. This paper describes the pilot feasibility study protocol for implementing a 12-week physical activity and healthy eating program, 'Get Healthy!' with older adults with intellectual disability.

METHODS

The primary study aims are to assess the feasibility of implementing and monitoring the 'Get Healthy!' program with adults with mild to moderate intellectual disability, aged 40 years and over, and their carers. Secondary study aims are to assess the impact of the intervention across the following parametres: body mass index, waist circumference, cardiovascular fitness, physical activity (amount and intensity) and sedentary behaviours, resting blood pressure, functional strength/capacity, dietary intake (energy intake, food group consumption and diet quality), dietary and physical activity knowledge, and quality of life. Between 8 and 10 participants in total will be recruited into the 12-week program that will be run in metropolitan NSW, Australia. A combination of objective and subjective measures will be used to assess program feasibility and impact at set timepoints (baseline, mid and end-program).

DISCUSSION

Results from the feasibility pilot will be used to refine the study methodology and 'Get Healthy!' program content for future use in a sufficiently powered trial. Findings may be of interest to a broad range of disability and allied health workers engaged in supporting and monitoring healthy lifestyle change in adults with intellectual disability.

Alcohol use disorders in people with intellectual disability

This article initially highlights that although the prevalence of alcohol use disorders in people with intellectual disability (PWID) appears to be low, it is a significant issue. This group can be more vulnerable to the adverse effects of alcohol and it is likely that many PWID who have alcohol use disorders are not being identified. We go on to review the limited existing literature on treatment for PWID who have alcohol use disorders and the challenges in meeting the needs of this patient group. We explore how assessment and treatment of alcohol use disorders in this population can be and needs to be tailored to the needs of PWID on an individual basis. There is also discussion about the use of incapacity legislation to treat this group.

Development of a supported self-management intervention for adults with type 2 diabetes and a learning disability

BACKGROUND

Although supported self-management is a well-recognised part of chronic disease management, it has not been routinely used as part of healthcare for adults with a learning disability. We developed an intervention for adults with a mild or moderate learning disability and type 2 diabetes, building on the principles of supported self-management with reasonable adjustments made for the target population.

METHODS

In five steps, we:Clarified the principles of supported self-management as reported in the published literatureIdentified the barriers to effective self-management of type 2 diabetes in adults with a learning disabilityReviewed existing materials that aim to support self-management of diabetes for people with a learning disabilitySynthesised the outputs from the first three phases and identified elements of supported self-management that were (a) most relevant to the needs of our target population and (b) most likely to be acceptable and useful to themImplemented and field tested the intervention.

RESULTS

The final intervention had four standardised components: (1) establishing the participant's daily routines and lifestyle, (2) identifying supporters and their roles, (3) using this information to inform setting realistic goals and providing materials to the patient and supporter to help them be achieved and (4) monitoring progress against goals.Of 41 people randomised in a feasibility RCT, thirty five (85%) completed the intervention sessions, with over three quarters of all participants (78%) attending at least three sessions.Twenty-three out of 40 (58%) participants were deemed to be very engaged with the sessions and 12/40 (30%) with the materials; 30 (73%) participants had another person present with them during at least one of their sessions; 15/41 (37%) were reported to have a very engaged main supporter, and 18/41 (44%) had a different person who was not their main supporter but who was engaged in the intervention implementation.

CONCLUSIONS

The intervention was feasible to deliver and, as judged by participation and engagement, acceptable to participants and those who supported them.

Understanding low levels of physical activity in people with intellectual disabilities: A systematic review to identify barriers and facilitators

BACKGROUND

People with intellectual disabilities (ID) undertake extremely low levels of physical activity.

AIMS

To enhance understanding concerning low levels of physical activity in people with ID, this study has three aims: (1) to identify barriers to and facilitators of physical activity in people with ID; (2) to examine differences in barriers and facilitators between levels of ID (mild, moderate, severe, and profound); (3) to examine differences in barriers and facilitators between various stakeholder groups.

METHODS AND PROCEDURES

A systematic search was performed using the following databases from the year 1990: MEDLINE, ERIC, and PsycINFO. The studies included were peer reviewed, available as full text, and written in English, addressing barriers to and facilitators of physical activity in people with ID. The quality of the studies was assessed using existing critical review forms. All studies were subjected to qualitative synthesis to identify and compare barriers and facilitators.

OUTCOMES AND RESULTS

In all, 24 studies were retrieved, describing 14 personal and 23 environmental barriers and/or facilitators. The quality of the studies varied, particularly for qualitative studies. Only two studies included people with severe or profound ID. Stakeholder groups tend to identify barriers outside their own responsibility.

CONCLUSIONS AND IMPLICATIONS

Results reveal a broad range of barriers and facilitators, but not for people with more severe ID. Further research should also examine these factors among stakeholders responsible for providing support.

Substance use among individuals with intellectual disabilities living independently in Flanders

BACKGROUND

Over the past decades, there has been increased scientific and clinical interest in substance use among individuals with intellectual disabilities (ID). Despite raised interest and awareness in the topic, lack of supportive data on prevalence and risk factors highlights the need for ongoing research. The aims of this cross-sectional multicenter study were to examine the nature and extent of substance use in individuals with ID living independently, to investigate group differences in substance use and related problems, and to explore the role of substance-related knowledge and attitudes in substance use behaviors.

METHOD

Participants were 123 individuals with mild to moderate ID receiving support from independent living services. Data were gathered by means of a structured interview strategy (i.e. the Substance Use and Misuse in Intellectual Disability-Questionnaire; SumID-Q).

RESULTS

Findings revealed that rates of lifetime use of licit and illicit substances were higher than those found in earlier studies among individuals with ID and the general population. While cannabis use was the only illicit substance reported, current tobacco and alcohol use were shown to be highly prevalent (48%-45.5%). Rates for the latter were similar to earlier studies among community samples of individuals with ID. In contrast to our hypotheses, few group differences in substance use behaviors were observed. Male gender was associated with age of onset of alcohol and tobacco use and tobacco use-related problems, while younger age was found to be associated with lifetime use of cannabis. No evidence was found regarding the role of knowledge; however, smokers and alcohol users rated tobacco and alcohol use more positively.

CONCLUSION

This study demonstrated that individuals with ID living independently use a wide range of licit and illicit substances and present divergent levels and patterns of substance use. Notwithstanding the role of personal choice in substance use, more research is needed to better understand the nature and extent of substance use and related problems, as well as the role of substance-related knowledge and attitudes in individuals with ID.

Definitions, measurement and prevalence of sedentary behaviour in adults with intellectual disabilities - A systematic review

Supporting positive change in lifestyle behaviours is a priority in tackling the health inequalities experienced by adults with intellectual disabilities. In this systematic review, we examine the evidence on the definition, measurement and epidemiology of sedentary behaviour of adults with intellectual disabilities. A systematic literature search of PUBMED, EMBASE, MEDLINE and Google Scholar was performed to identify studies published from 1990 up to October 2015. Nineteen papers met the criteria for inclusion in the systematic review. Many researchers do not distinguish between insufficient physical activity and sedentary behaviour. None of the studies reported the reliability and validity of the methods used to measure sedentary behaviour. Sedentary time, assessed objectively, ranged from 522 to 643min/day: higher than in adults without intellectual disabilities. This first-ever review of sedentary behaviour and intellectual disabilities found that at present the evidence base is weak. Studies calibrating accelerometer data with criterion measures for sedentary behaviour are needed to determine specific cut-off points to measure sedentary behaviour in adults with intellectual disabilities. Researchers should also examine the reliability and validity of using proxy-report questionnaires to measure sedentary behaviour in this group. A better understanding of sedentary behaviour will inform the design of novel interventions to change lifestyle behaviours of adults with intellectual disabilities.

Use of behaviour change techniques in lifestyle change interventions for people with intellectual disabilities: A systematic review

BACKGROUND

People with intellectual disabilities (ID) experience more health problems and have different lifestyle change needs, compared with the general population.

AIMS

To improve lifestyle change interventions for people with ID, this review examined how behaviour change techniques (BCTs) were applied in interventions aimed at physical activity, nutrition or physical activity and nutrition, and described their quality.

METHODS AND PROCEDURES

After a broad search and detailed selection process, 45 studies were included in the review. For coding BCTs, the CALO-RE taxonomy was used. To assess the quality of the interventions, the Physiotherapy Evidence Database (PEDro) scale was used. Extracted data included general study characteristics and intervention characteristics.

OUTCOMES AND RESULTS

All interventions used BCTs, although theory-driven BCTs were rarely used. The most frequently used BCTs were 'provide information on consequences of behaviour in general' and 'plan social support/social change'. Most studies were of low quality and a theoretical framework was often missing.

CONCLUSION AND IMPLICATIONS

This review shows that BCTs are frequently applied in lifestyle change interventions. To further improve effectiveness, these lifestyle change interventions could benefit from using a theoretical framework, a detailed intervention description and an appropriate and reliable intervention design which is tailored to people with ID.

Hospitalisation in adults with intellectual disabilities compared with the general population in Norway

BACKGROUND

Previous studies have found that adults with intellectual disabilities (ID) are hospitalised more often than the general population (GP). This study investigates hospital discharge rates and main diagnostic causes for hospitalisation among administratively defined people with ID compared with the GP in Norway.

METHOD

Data from the Norwegian Labour and Welfare Service was combined with data from the Norwegian Patient Register (N_total  = 1 764 072 and N_ID  = 7573) for the period 2008-2011. Data from a Norwegian patient report generator and Statistics Norway are also analysed.

RESULTS

During the study period, 11% of people with ID and 11.5% of the GP were admitted to hospitals. The length of the average hospital stay was just over 4 days for both groups. Among those who were hospitalised, the majority were only admitted to hospital once during the study period: ID 66% and GP 70%. People with ID were admitted somewhat more often than people in the GP. Contrary to the GP, adults with ID were more frequently hospitalised at a younger age and less frequently at old age. The most common International Classification of Diseases diagnostic group for hospitalisation among people with ID is injury, poisoning and certain other consequences of external causes, whereas for the GP, it is diseases of the circulatory system.

CONCLUSION

This study finds that the proportion of people being hospitalised per year is statistically, but only slightly, different among adult people with ID and the GP. The results must be interpreted in light of the organisation of the health care system in Norway.

Healthy living according to adults with intellectual disabilities: towards tailoring health promotion initiatives

BACKGROUND

A healthy lifestyle can prevent several health problems experienced by adults with intellectual disabilities (ID). For the development of effective and usable health promoting interventions for people with ID, the perspective of the intended audience should be taken into account. The aim of this qualitative study was to gain insight into the perspectives of people with mild to moderate ID on healthy living.

METHOD

Qualitative study. Five semi-structured focus groups were conducted with a total of 21 adults with mild to moderate ID in the Netherlands. Discussions focused on three main themes: (1) perceptions of own health, (2) what participants consider as healthy living and (3) factors experienced to be related to the ability to live healthily. Interviews were analysed thematically resulting in two main domains: (1) perceptions of what is healthy and unhealthy and (2) factors that participants experience to be related to their ability to live healthily.

RESULTS

For participants, healthy living entails more than healthy food and exercising: feeling healthy, happiness and level of independence are perceived as important as well. Factors experienced to relate to their ability to live healthily were (a lack of) motivation, support from others and environmental factors such as available health education, (a lack of) facilities and a(n) (dis)advantageous location of work or residence.

CONCLUSIONS

This qualitative study shows that adults with mild to moderate ID have a good understanding of what being healthy and living healthily constitute. As they face several difficulties in their attempts to live healthily, existing health promotion programmes for people with ID must be tailored to individual preferences and motivations and adapted for individual physical disabilities. Moreover, because of their dependency on others, tailoring should also be focused on the resources and hindering factors in their physical and social environment.

Development of physical fitness in children with intellectual disabilities

BACKGROUND

Few studies examined the development of physical fitness in children and youth with intellectual disabilities (ID), but the developmental patterns of physical fitness are largely unknown. The first aim was to examine physical fitness of primary school children with ID, aged 8-12, and compare the results with typically developing children in order to determine the performance level of children with ID. The second aim was to investigate the developmental trajectory of physical fitness in children with ID and the possible influence of gender and severity of cognitive impairment in a 4-year during longitudinal study.

METHOD

Seventy-three children with borderline or mild ID (51 boys, 22 girls; age range 8-11 in the year of enrolment) were measured annually on running speed, aerobic endurance (cardiovascular endurance), explosive strength, handgrip strength and trunk strength. Physical fitness scores of 515 typically developing children (266 boys, 249 girls; age range 8-12) were collected for reference values.

RESULTS

The results indicated statistically significant differences (with moderate to large Effect Sizes) between children with ID and typically developing children in all ages, favouring the typically developing children, and showed that the gap remained stable across the ages or decreased with increasing age. Multilevel models showed that the children with ID developed statistically significant on all items of physical fitness between age 8 and age 12. There was no statistically significant effect of gender on physical fitness, and the developmental trajectories were similar for boys and girls. For children with borderline and mild ID the developmental trajectories were parallel, but children with mild ID scored statistically significant worse on running speed, explosive strength and handgrip strength.

CONCLUSIONS

Despite statistically significant development of physical fitness in children with ID, their physical fitness levels should be stimulated. This should start already in young children (<8 years) and the children with the most severe cognitive impairments need special attention.

The Effectiveness of a Weight Maintenance Intervention for Adults with Intellectual Disabilities and Obesity: A Single Stranded Study

BACKGROUND

The evidence base for weight management programmes incorporating a weight loss and a weight maintenance phase for adults with intellectual disabilities (ID) is limited. This study describes the weight maintenance phase of a multicomponent weight management programme for adults with intellectual disability and obesity (TAKE 5).

MATERIALS AND METHODS

Thirty-one participants who had completed the 16 week TAKE five weight loss intervention (Phase I) were invited to participate in a 12 month weight maintenance intervention (Phase II). Content included recommendations of the National Weight Control Registry.

RESULTS

Twenty-eight participants completed Phase II with 50.4% maintaining their weight (mean weight change -0.5 kg, SD 2.2), 28.7% gaining weight (mean weight gain 5.4 kg, SD 2.2) and 21.6% losing weight (mean weight loss -8.0 kg, SD 3.0) at 12 months.

CONCLUSION

Further research is justified to investigate the efficacy of weight loss maintenance interventions in adults with intellectual disability and obesity, using controlled study designs.

Effects of declared levels of physical activity on quality of life of individuals with intellectual disabilities

Routine physical fitness improves health and psychosocial well-being of individuals with intellectual and developmental disabilities. The current study investigated impact of physical fitness on quality of life by comparing individuals who maintain a physically active lifestyle with those who do not report exercising. We assessed several indicators of quality of life, including inclusion and community participation; satisfaction with professional services, home life, and day activities; dignity, rights, and respect received from others; fear; choice and control; and family satisfaction. Our data suggested that individuals who regularly exercise reported having more frequent outings into the community than did their peers who reported exercising infrequently; regular exercisers were also more likely to live in intermediate care facilities (ICF) as opposed to living independently or with family members. We discuss possible reasons for this as well as ideas for future research needed to expand on this area.
