Exploring the relationship between sleep and aggression in adolescents: A cross sectional study using the UK Millennium cohort study

This study aimed to establish if a significant relationship exists between sleep and aggression in a large representative adolescent cohort and explores the impact of potential confounders. This cross-sectional secondary data analysis included 10,866 males and females aged 13-15 years, from the UK-based 2015 Millenium Cohort Study (sixth sweep). Independent variables included self-report measures of sleep duration and quality. The parent reported 'Strengths and Difficulties Questionnaire' conduct score measured aggression. Binary logistic regression examined independent associations between each sleep variable and aggression. Multiple regression models then adjusted for potential confounders: age, sex, socioeconomic status, arousal, and affect. Under 8 hours of sleep on average was significantly associated with aggression when age, sex and income were controlled (p = .008). This became insignificant following adjustment for both affect and arousal. Sleep quality remained significantly associated with aggression when all confounders were controlled: 'sleep onset latency >30 minutes' and 'wakening at least a good bit of the time' increased the odds of aggression by around 27.9% (p < .001) and 43.5% respectively (p < .001). A significant association exists between poor subjective sleep quality and heightened aggression in this cohort, when all our confounders are controlled, identifying sleep quality as a potential target in treating adolescent aggression.

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.

Individual, interpersonal and environmental correlates of sedentary behaviours in adults with intellectual disabilities

BACKGROUND

Sedentary behaviours have adverse health outcomes and adults with intellectual disabilities are at a higher risk of unhealthy lifestyle behaviours. The lack of knowledge relating to sedentary behaviours in adults with intellectual disabilities has impeded the development of effective interventions. This study aimed to investigate individual, interpersonal and environmental correlates that are associated with sedentary behaviours in adults with intellectual disabilities.

METHOD

A secondary analysis of data from The UK Household Longitudinal Study (Understanding Society; collected 2011-2013) was conducted. Twenty-two predictor variables were included in a stepwise logistic regression, with TV hours during weekdays (≤3 and >3 h/day) used as a proxy for sedentary behaviours. A sample of 266 adults, with mean age of 37.9 and range from 18 to 49 years old, with intellectual disabilities were identified. Because 63.9% were female, 62.4% had children and 28.2% were employed, the sample is likely to be most representative of more able adults with intellectual disabilities.

RESULTS

A significant interaction term between having children and neighbourhood status was found in the initial model so separate models for good and poor-quality neighbourhoods are reported. Having children only had a significant effect to lower the odds of high TV time among participants living in good quality neighbourhoods (OR 0.10, 95% CI 0.03, 0.25). However, for people living in poor quality neighbourhoods it was better quality leisure services that was associated with lower odds of high TV time (OR 0.48, 95% CI 0.23, 0.90). Being employed only significantly reduced the odds of high TV time in the good quality neighbourhood model (OR 0.35, 95% CI 0.12, 0.78). These effects highlight the importance of environmental effects on lifestyle behaviours of adults with intellectual disabilities.

CONCLUSIONS

Future research should aim to expand our understanding of environmental effects on the sedentary behaviours and other lifestyle behaviours of adults with intellectual disabilities.

Predictors and moderators of the response of adults with intellectual disabilities and depression to behavioural activation and guided self-help therapies

BACKGROUND

No previous studies have reported predictors and moderators of outcome of psychological therapies for depression experienced by adults with intellectual disabilities (IDs). We investigated baseline variables as outcome predictors and moderators based on a randomised controlled trial where behavioural activation was compared with guided self-help.

METHODS

This study was an exploratory secondary data analysis of data collected during a randomised clinical trial. Participants (n = 161) were randomised to behavioural activation or guided self-help and followed up for 12 months. Pre-treatment variables were included if they have previously been shown to be associated with an increased risk of having depression in adults with IDs or have been reported as a potential predictor or moderator of outcome of treatment for depression with psychological therapies. The primary outcome measure, the Glasgow Depression Scale for Adults with Learning Disabilities (GDS-LD), was used as the dependant variable in mixed effects regression analyses testing for predictors and moderators of outcome, with baseline GDS-LD, treatment group, study centre and antidepressant use as fixed effects, and therapist as a random effect.

RESULTS

Higher baseline anxiety (mean difference in outcome associated with a 1 point increase in anxiety 0.164, 95% confidence interval [CI] 0.031, 0.297; P = 0.016), lower performance intelligence quotient (IQ) (mean difference in outcome associated with a 1 point increase in IQ 0.145, 95% CI 0.009, 0.280; P = 0.037) and hearing impairment (mean difference 3.449, 95% CI 0.466, 6.432; P = 0.024) were predictors of poorer outcomes, whilst greater severity of depressive symptoms at baseline (mean difference in outcome associated with 1 point increase in depression -0.160, 95% CI -0.806, -0.414; P < 0.001), higher expectation of change (mean difference in outcome associated with a 1 point increase in expectation of change -1.013, 95% CI -1.711, -0.314; p 0.005) and greater percentage of therapy sessions attended (mean difference in outcome with 1 point increase in percentage of sessions attended -0.058, 95% CI -0.099, -0.016; P = 0.007) were predictors of more positive outcomes for treatment after adjusting for randomised group allocation. The final model included severity of depressive and anxiety symptoms, lower WASI performance IQ subscale, hearing impairment, higher expectation of change and percentage of therapy sessions attended and explained 35.3% of the variance in the total GDS-LD score at 12 months (R2  = 0.353, F4, 128  = 17.24, P < 0.001). There is no evidence that baseline variables had a moderating effect on outcome for treatment with behavioural activation or guided self-help.

CONCLUSIONS

Our results suggest that baseline variables may be useful predictors of outcomes of psychological therapies for adults with IDs. Further research is required to examine the value of these potential predictors. However, our findings suggest that therapists consider how baseline variables may enable them to tailor their therapeutic approach when using psychological therapies to treat depression experienced by adults with IDs.

Associations between motor competence and physical activity levels of children with intellectual disabilities and/or autism spectrum disorder: Movement matters

Motor competence is important for lifelong physical activity (PA). The current study aimed to examine associations between PA and motor competence. In total, 43 children aged 7-12 years with intellectual disabilities and/or autism spectrum disorder completed anthropometric measures, the Bruininks-Oseretsky Test of Motor Proficiency-2, and wore a wrist accelerometer to capture total PA, moderate-to-vigorous PA (MVPA), average acceleration, and intensity gradient. No significant associations were found between PA outcomes and motor competence. Motor competence performance was commonly 'below average' or 'average'. The weakest subtests were upper limb coordination and strength. The strongest subtest was running speed and agility. Total weekly MVPA was 336.1 ± 150.3 min, higher than UK recommendations of 120-180 per week for disabled children and young people. Larger scale studies are needed to better understand the relationship between PA and motor competence. Future research should also consider the influence of environmental factors on PA in this group.

Correlates of physical activity in children and adolescents with intellectual disabilities: a systematic review

BACKGROUND

Children and adolescents with intellectual disabilities (ID) participate in low levels of physical activity. To inform the development of interventions, we need to better understand factors associated with physical activity. The aim of this study was therefore to systematically review correlates of physical activity in children and adolescents 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 between 1 January 1990 and 29 February 2020 to identify English-language studies, which examined correlates of free-living physical activity in children and adolescents (0-19 years) with ID. Study quality was assessed. Correlates were analysed using a narrative synthesis and classified using the socioecological model as intrapersonal, interpersonal, organisational or environmental.

RESULTS

Fifteen studies published between 2010 and 2019 met the inclusion criteria and were included in the review. Forty-eight individual correlates were identified. Studies were predominantly focused on intrapersonal-level correlates. Of those correlates investigated in more than one study (n = 6), having better motor development was positively associated with physical activity. Inconsistent results were found for age and cardiorespiratory fitness. Sex, percentage body fat and body mass index were not correlated. No interpersonal-level, organisational-level or environmental-level correlates were included in more than one study.

CONCLUSIONS

To date, we have limited and inconclusive evidence about correlates of physical activity in children and adolescents with ID. Only when future studies unravel correlates and determinants, across all domains of the socioecological model, will the potential opportunities to improve health by increasing physical activity levels be achievable.

Motor competence assessments for children with intellectual disabilities and/or autism: a systematic review

OBJECTIVE

Gross motor competence is essential for daily life functioning and participation in physical activities. Prevalence of gross motor competence in children with intellectual disabilities (ID) and/or autism is unclear. This systematic review aimed to identify appropriate assessments for children with ID and/or autism.

DESIGN & DATA SOURCES

An electronic literature search was conducted using the EBSCOhost platform searching MEDLINE, Education Research Complete, ERIC, CINAHL Plus and SPORTDiscus databases.

ELIGIBILITY CRITERIA

Included studies sampled children with ID and/or autism aged between 1 and 18 yrs, used field-based gross motor competence assessments, reported measurement properties, and were published in English. The utility of assessments were appraised for validity, reliability, responsiveness and feasibility.

RESULTS

The initial search produced 3182 results, with 291 full text articles screened. 13 articles including 10 assessments of motor competence were included in this systematic review. There was limited reporting across measurement properties, mostly for responsiveness and some aspects of validity. The Bruininks-Oseretsky Test of Motor Proficiency-2 followed by The Test of Gross Motor Development-2 demonstrated the greatest levels of evidence for validity and reliability. Feasibility results were varied, most instruments required little additional equipment (n=8) and were suitable for a school setting, but, additional training (n=7) was needed to score and interpret the results.

CONCLUSION

This review found the BOT-2 followed by the TGMD-2 to be the most psychometrically appropriate motor competency assessments for children with ID and/or autism in field-based settings. Motor competence assessment research is limited for these cohorts and more research is needed.

Exploring parents' experiences of promoting physical activity for their child with intellectual disabilities

INTRODUCTION

Children and adolescents with intellectual disabilities participate in low levels of physical activity and have a greater reliance on their parents to provide activity opportunities. This study explored parents' experiences of promoting physical activity for their child with intellectual disabilities.

METHODS

Semi-structured interviews were conducted with eight parents of children and adolescents with intellectual disabilities. Interviews were independently coded and analysed by two researchers using thematic analysis.

RESULTS

Four themes and nine subthemes were identified. Overall, parents had positive views of physical activity. However, parents face numerous barriers that limit their ability to promote physical activity for their child with intellectual disabilities.

CONCLUSIONS

Parents experience high levels of exclusion and stigma that negatively affect their promotion of physical activity for their child with intellectual disabilities. Overcoming the barriers faced by parents could therefore be an indirect method to increase physical activity in children and adolescents with intellectual disabilities.

Cultural adaptation of self-management of type 2 diabetes in Saudi Arabia (qualitative study)

Background

Saudi Arabia is continuously working on developing its health care system, however with the high prevalence of type 2 diabetes and comorbidities, such as cardiovascular diseases, self-management education programmes are essential. As part of a planned series of studies to develop a culturally sensitive type 2 diabetes self-management programme, this study explores the need versus barriers and facilitators relevant to implementing a national programme for type 2 diabetes self-management education within the community and health care system in Saudi Arabia.

Methods

A qualitative methodology was used to explore the views of a multidisciplinary group of diabetes health professionals and adult patients with type 2 diabetes. The views of nine health professionals working at a specialised diabetes care centre were gathered at two focus groups (four and five) that included doctors, nutritionists, health educators and nurses. Individual interviews with 12 patients with type 2 diabetes (six females and six males) attending the centre were also carried out. Recurring themes through the translated transcripts were studied and treated by the research group under pre-set protocols.

Results

Focus groups with health professionals revealed three main themes. 1. Resources: availability of resources and how they impacted on performance and patients’ care; 2.Familiarity with self-management education programmes: educating patients and raising awareness among them; and 3. Lifestyle: patients’ lifestyle and how it could affect their compliance with self-management programmes. Interviews with patients also revealed three main themes. 1. Habits: post diagnosis changes in patients’ attitudes and behaviours towards diet and physical activity; 2. Health education: awareness of managing type 2 diabetes through health centre advice or self-education; and 3. Culture and society: a lack of cultural or social support created by some social practices or conventions.

Conclusion

The findings from this study highlight a gap in type 2 diabetes care system that can be breached through the development of a Saudi specific self-management programme for type 2 diabetes. The identified barriers and facilitators can be used for adapting a self-management programme to the Saudi context. However, initial training is needed for local health professionals to understand the mechanisms of self-management programmes. Such programmes will need to infiltrate to the society, and the patients’ families, in particular to tackle the rising prevalence of type 2 diabetes in Saudi Arabia and provide a friendlier, more supportive environment for the current patients to self-manage their diabetes.

Correlates of type 2 diabetes and glycaemic control in adults in Saudi Arabia a secondary data analysis of the Saudi health interview survey

BACKGROUND

There is evidence that type 2 diabetes self-management programmes may have a positive impact on health outcomes of adults living in Gulf countries. However, none of the programmes evaluated were developed using evidence about the specific needs of adults with Type 2 diabetes living in the Gulf countries. This study is part of a wider programme of research, which uses a cultural adaptation framework to generate information on how to tailor type 2 diabetes self-management to the Saudi context.

METHODS

Secondary data analysis of the Saudi Health Interview Survey (SHIS) (N = 10,821) was conducted. Bivariate and multivariate logistic regression modelling assessed factors associated with type 2 diabetes and its control / self-management including sociodemographic factors (e.g. age, gender), lifestyle (e.g. diet, physical activity), and health seeking behaviours (e.g. chronic illnesses, health services).

RESULTS

7% (N = 808) of all participants had type 2 diabetes (59% male), however it represents 35% at or above 55 years. In multivariate analysis at older age, being overweight or obese, male, having hypertension, and reporting a reduction in health status in the 12 months prior to questionnaire completion, were significantly associated with having type 2 diabetes. Participants who reported walking for more than 10 min per day were less likely to report type 2 diabetes. Unexpectedly there was a significant association between type 2 diabetes and lower frequency of fast food intake, while increased fruit and vegetable intake was associated with poor glycaemic control.

CONCLUSIONS

Being overweight and/or hypertensive are concomitant with type 2 diabetes in Saudi Arabia. Any self-management programmes for type 2 diabetes patients with either of these conditions should be tailored accordingly. Walking behaviours should be prioritised in Saudi self-management programmes. Prediabetes management programmes may be of special importance to the Saudi community.

Gender differences in physical activity and sedentary behaviour in adults with intellectual disabilities: A systematic review and meta-analysis

BACKGROUND

Adults with intellectual disabilities are reported to be highly inactive, with research required to understand contributory factors. This systematic review aimed to investigate gender differences in physical activity (PA) and sedentary behaviour (SB) in adults with intellectual disabilities.

METHODS

This systematic review was reported in accordance with PRISMA guidelines. Seven databases were searched up to, and including, January 2018. Screening identified papers that assessed gender-specific PA and/or SB outcomes in adults with intellectual disabilities. Data were synthesized using a narrative synthesis and random effects model meta-analyses.

RESULTS

Twenty-six papers were included; 25 measured PA, and eight assessed SB. Women with intellectual disabilities were least active with a significant overall effect of gender identified. For SB, no consistent gender differences were found.

CONCLUSIONS

Reflecting the general population, men with intellectual disabilities were most active. Intellectual disability research should consider the role of gender to inform future interventions targeting inactivity.

Patterns of objectively measured sedentary behaviour in adults with intellectual disabilities

BACKGROUND

The purpose of this study was to investigate the patterns of objectively measured sedentary behaviour in adults with intellectual disabilities.

METHODS

Baseline accelerometer data were pooled from two randomized controlled trials of lifestyle behaviour change programmes for adults with intellectual disabilities. Patterns of sedentary behaviours were computed including total volume, number, and duration of bouts and breaks.

RESULTS

Participants spent >70% of the day sedentary (8 hr), which was generally accumulated in short sedentary bouts (<10 min). Participants were engaged in significantly more sedentary time during the morning, although differences between time of day were small (mean bout duration range: 19.8-22.3 min).

CONCLUSIONS

The findings add valuable insight into the patterns of sedentary behaviours among adults with intellectual disabilities. Further research investigating the patterns and context of sedentary behaviour is required to develop targeted interventions to reduce total sedentary time in adults with intellectual disabilities.

Process evaluation of a cluster-randomised controlled trial of multi-component weight management programme in adults with intellectual disabilities and obesity

BACKGROUND

Providing effective weight management to adults with intellectual disabilities is necessary to challenge the high rates of obesity. The aim of this process evaluation was to explore the feasibility of conducting a full-scale clinical trial of the TAKE 5 multi-component weight management programme.

METHODS

The study was a 12-month pilot cluster-randomised controlled trial. Adults with intellectual disabilities and obesity were randomised to either TAKE 5, which included an energy deficit diet (EDD) or Waist Winners Too, based on health education principles. A mixed-methods process evaluation was conducted focussing on the reach, recruitment, fidelity, implementation, dose (delivered/received) and context.

RESULTS

The study successfully recruited adults with intellectual disabilities. Both weight management programmes were delivered with high fidelity and implemented as intended. Only one weight management programme, TAKE 5, demonstrated potential efficacy in reducing body weight and body composition. The effectiveness was largely attributed to the EDD and social support from carers.

CONCLUSIONS

The extensive process evaluation illustrated that a full-scale trial of a multi-component programme including an EDD is feasible and an acceptable approach to weight management for adults with intellectual disabilities and obesity.

Embedding routine health checks for adults with intellectual disabilities in primary care: practice nurse perceptions

BACKGROUND

Adults with intellectual disabilities (IDs) have consistently poorer health outcomes than the general population. There is evidence that routine health checks in primary care may improve outcomes. We conducted a randomised controlled trial of practice nurse led health checks. Here, we report findings from the nested qualitative study.

AIM

To explore practice nurse perceptions and experience of delivering an anticipatory health check for adults with IDs.

DESIGN AND SETTING

Qualitative study in General Practices located in NHS Greater Glasgow and Clyde, Scotland, UK.

METHOD

Eleven practice nurses from 11 intervention practices participated in a semi-structured interview. Analysis was guided by a framework approach.

RESULTS

Practice nurses reported initially feeling 'swamped' and 'baffled' by the prospect of the intervention, but early misgivings were not realised. Health checks were incorporated into daily routines with relative ease, but this was largely contingent on existing patient engagement. The intervention was thought most successful with patients already well known to the practice. Chronic disease management models are commonly used by practice nurses and participants tailored health checks to existing practice. It emerged that few of the nurses utilised the breadth of the check instead modifying the check to respond to individual patients' needs. As such, already recognised 'problems' or issues dominated the health check process. Engaging with the health checks in this way appeared to increase the acceptability and feasibility of the check for nurses. There was universal support for the health check ethos, although some questioned whether all adults with IDs would access the health checks, and as a consequence, the long-term benefits of checks.

CONCLUSION

While the trial found the intervention to be dominant over standard health care, the adjustments nurses made may not have maximised potential benefits to patients. Increasing training could further improve the benefits that health checks provide for people with IDs.

A systematic review and meta-analysis of interventions to increase physical activity in children and adolescents with intellectual disabilities

BACKGROUND

Increasing physical activity (PA) through intervention can promote physical and mental health benefits in children and adolescents. However, children and adolescents with intellectual disabilities (ID) have consistently been shown to engage in low levels of PA, which are insufficient for long-term health. Despite this, little is known about the effectiveness of interventions to increase PA in children and adolescents with ID. The aims of this study were therefore to systematically review how effective interventions are at increasing PA levels in children and adolescents with ID and to further examine what components have been used in these interventions.

METHOD

A systematic search of MEDLINE, EMBASE, Education Resources Information Center, Cumulative Index to Nursing and Allied Health Literature, PsychINFO, Cochrane Central Register for Controlled Trials and International Standard Randomised Controlled Trial Number trials registry was conducted (up to July 2016). Articles were included if they met the following eligibility criteria: children and adolescents (<18 years) with ID, measurement of PA at baseline and post-intervention and intervention studies. Effect sizes were calculated as standardised mean difference (d) and meta-analysis calculated between intervention and no treatment control intervention.

RESULTS

Five studies met the eligibility criteria and were included in the review. Study design, methodological quality and intervention components were varied. Interventions did not support sufficient changes in PA to improve health. The meta-analysis demonstrated that intervention groups were not more effective at increasing PA levels post-intervention (d: 2.20; 95% CI -0.57 to 0.97) compared with control. However, due to a decrease in PA in the control intervention, a moderate significant effect was demonstrated at follow-up (d: 0.49; 95% CI 0.14 to 0.84).

CONCLUSIONS

There is a lack of studies which aim to increase PA levels in children and adolescents with ID, with current interventions ineffective. Future studies are required before accurate recommendations for appropriate intervention design and components can be made.

Correlates of objectively measured sedentary time in adults with intellectual disabilities

Sedentary behaviour is an independent risk factor for adverse health conditions. Adults with intellectual disabilities spend a high proportion of their day engaged in sedentary behaviour, however, there is limited evidence on potential correlates of objectively measured sedentary behaviour in this population group. In Glasgow, UK from July to September 2017, a secondary analysis of pooled baseline accelerometer data from two randomised controlled trials of lifestyle behaviour change programmes was conducted. Backwards linear regression was used to investigate the associations between demographic, biological, and environmental correlates and objective measure of sedentary behaviour (percentage of time spent sedentary). One-hundred and forty-three participants provided valid accelerometer data. Mean percentage time spent sedentary (adjusted for wear time) was 72.9% [Standard Deviation (SD) = 8.7] per day. In the final model, physical and mental health problems were significantly (p < 0.05) associated with increased percentage time spent sedentary. This is the first study to provide evidence on multi-level, demographic, biological, and environmental correlates of objectively measured sedentary behaviour in adults with intellectual disabilities. To inform the development of interventions to modify sedentary behaviours in adults with intellectual disabilities, further research is required including a wide range of socio-ecological correlates.

Parental perceptions of facilitators and barriers to physical activity for children with intellectual disabilities: A mixed methods systematic review

BACKGROUND

There is a need increase our understanding of what factors affect physical activity participation in children with intellectual disabilities (ID) and develop effective methods to overcome barriers and increase activity levels.

AIM

This study aimed to systematically review parental perceptions of facilitators and barriers to physical activity for children with ID.

METHODS

A systematic search of Embase, Medline, ERIC, Web of Science, and PsycINFO was conducted (up to and including August, 2017) to identify relevant papers. A meta-ethnography approach was used to synthesise qualitative and quantitative results through the generation of third-order themes and a theoretical model.

RESULTS

Ten studies were included, which ranged from weak to strong quality. Seventy-one second-order themes and 12 quantitative results were extracted. Five third-order themes were developed: family, child factors, inclusive programmes and facilities, social motivation, and child's experiences of physical activity. It is theorised that these factors can be facilitators or barriers to physical activity, depending on the information and education of relevant others, e.g. parents and coaches.

CONCLUSIONS

Parents have an important role in supporting activity in children with ID. Increasing the information and education given to relevant others could be an important method of turning barriers into facilitators.

A population-based, cross-sectional study of the prevalence and correlates of sedentary behaviour of adults with intellectual disabilities

BACKGROUND

High levels of sedentary behaviour have a negative impact on health and well-being. There is limited evidence on the prevalence and correlates of sedentary behaviour of adults with intellectual disabilities (ID).

METHODS

A population-based sample of adults with ID were invited to take part in a comprehensive health check programme. Demographic and health data were collected during a structured interview and physical examination. Screen time was used as a proxy measure of sedentary behaviour. Bivariate and multivariate statistical modelling examined correlates of screen time.

RESULTS

Fifty per cent of the 725 participants reported four or more hours of screen time per day. Male gender, higher levels of intellectual ability, mobility problems, obesity, not having hearing impairment and not having epilepsy were all significantly associated with higher screen time in the final multivariate model (R²  = 0.16; Hosmer-Lemeshow goodness of fit statistic P = 0.36).

CONCLUSIONS

This is the first study to publish population-based data on the prevalence and correlates of sedentary behaviour in adults with ID. Compared with adults who do not have ID, adults with ID have higher levels, and different correlates, of sedentary behaviour. A better understanding of the social context of sedentary behaviour will inform the design of effective behaviour change programmes for adults with ID.

Self-management of type 2 diabetes in gulf cooperation council countries: A systematic review

Aims

This study aimed to systematically review intervention studies on self-management of type 2 diabetes in Gulf Cooperation Council (GCC) countries to determine the most effective self-management strategies for individuals with type 2 diabetes in this region.

Methods

A search strategy was developed using multiple databases: Medline and Embase (via Ovid), CINAHL (via EBSCO), and PubMed. Study and intervention characteristics, intervention structure, content, cultural adaptation, and outcomes were extracted from the included studies. To be included in the review the studies should have met the following criteria: have examined the effectiveness of at least one intervention involving a type 2 DSME programme, have involved participants over 18 years old diagnosed with type 2 diabetes, have taken place to in a GCC country, have a study design that was observational, quasi-experimental or controlled, have reported at least one individual and have a quantitative outcome. A narrative data synthesis was used to describe the studies and comment on their methodological quality.

Results

Of the 737 retrieved papers, only eight met the inclusion criteria. Only one study was a randomised controlled trial. A statistically significant improvement in HbA1c was reported in five of the eight studies. There was a significant improvement in physical activity levels as reported in four of the eight studies. Only three studies referred to aspects of cultural design or adaptation of the intervention implemented.

Conclusions

Self-management interventions may have a positive impact on HbA1 levels in patients with type 2 diabetes in the GCC area. A greater emphasis placed on culturally appropriate self-management programmes may improve the effectiveness of self-management interventions for adults with type 2 diabetes in the GCC.

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.

Calibration and Cross-Validation of the ActiGraph wGT3X+ Accelerometer for the Estimation of Physical Activity Intensity in Children with Intellectual Disabilities

Background

Valid objective measurement is integral to increasing our understanding of physical activity and sedentary behaviours. However, no population-specific cut points have been calibrated for children with intellectual disabilities. Therefore, this study aimed to calibrate and cross-validate the first population-specific accelerometer intensity cut points for children with intellectual disabilities.

Methods

Fifty children with intellectual disabilities were randomly assigned to the calibration (n = 36; boys = 28, 9.53±1.08yrs) or cross-validation (n = 14; boys = 9, 9.57±1.16yrs) group. Participants completed a semi-structured school-based activity session, which included various activities ranging from sedentary to vigorous intensity. Direct observation (SOFIT tool) was used to calibrate the ActiGraph wGT3X+, which participants wore on the right hip. Receiver Operating Characteristic curve analyses determined the optimal cut points for sedentary, moderate, and vigorous intensity activity for the vertical axis and vector magnitude. Classification agreement was investigated using sensitivity, specificity, total agreement, and Cohen’s kappa scores against the criterion measure of SOFIT.

Results

The optimal (AUC = .87−.94) vertical axis cut points (cpm) were ≤507 (sedentary), 1008−2300 (moderate), and ≥2301 (vigorous), which demonstrated high sensitivity (81−88%) and specificity (81−85%). The optimal (AUC = .86−.92) vector magnitude cut points (cpm) of ≤1863 (sedentary), 2610−4214 (moderate), and ≥4215 (vigorous) demonstrated comparable, albeit marginally lower, accuracy than the vertical axis cut points (sensitivity = 80−86%; specificity = 77−82%). Classification agreement ranged from moderate to almost perfect (κ = .51−.85) with high sensitivity and specificity, and confirmed the trend that accuracy increased with intensity, and vertical axis cut points provide higher classification agreement than vector magnitude cut points.

Conclusions

This study provides the first valid methods of interpreting accelerometer output in children with intellectual disabilities. The calibrated physical activity cut points are notably higher than existing cut points, thus raising questions on the validity of previous low physical activity estimates in children with intellectual disabilities that were based on typically developing cut points.

Problem behaviours and symptom dimensions of psychiatric disorders in adults with intellectual disabilities: An exploratory and confirmatory factor analysis

BACKGROUND

The limited evidence on the relationship between problem behaviours and symptoms of psychiatric disorders experienced by adults with intellectual disabilities leads to conflict about diagnostic criteria and confused treatment. This study examined the relationship between problem behaviours and other psychopathology, and compared the predictive validity of dimensional and categorical models experienced by adults with intellectual disabilities.

METHODS

Exploratory and confirmatory factor analyses appropriate for non-continuous data were used to derive, and validate, symptom dimensions using two clinical datasets (n=457; n=274). Categorical diagnoses were derived using DC-LD. Severity and 5-year longitudinal outcome was measured using a battery of instruments.

RESULTS

Five factors/dimensions were identified and confirmed. Problem behaviours were included in an emotion dysregulation-problem behaviour dimension that was distinct from the depressive, anxiety, organic and psychosis dimensions. The dimensional model had better predictive validity than categorical diagnosis.

CONCLUSIONS

International classification systems should not include problem behaviours as behavioural equivalents in diagnostic criteria for depression or other psychiatric disorders. Investigating the relevance of emotional regulation to psychopathology may provide an important pathway for development of improved interventions.

WHAT THIS PAPER ADDS

There is uncertainty whether new onset problem behaviours or a change in longstanding problem behaviours should be considered as symptoms of depression or other types of psychiatric disorders in adults with intellectual disabilities. The validity of previous studies was limited by the use of pre-defined, categorical diagnoses or unreliable statistical methods. This study used robust statistical modelling to examine problem behaviours within a dimensional model of symptoms. We found that problem behaviours were included in an emotional dysregulation dimension and not in the dimension that included symptoms that are typical of depression. The dimensional model of symptoms had greater predictive validity than categorical diagnoses of psychiatric disorders. Our findings suggest that problem behaviours are a final common pathway for emotional distress in adults with intellectual disabilities so clinicians should not use a change in problem behaviours as a diagnostic criterion for depression, or other psychiatric disorders.

Statistical modelling studies examining the dimensional structure of psychopathology experienced by adults with intellectual disabilities: Systematic review

Diagnosing mental ill-health using categorical classification systems has limited validity for clinical practice and research. Dimensions of psychopathology have greater validity than categorical diagnoses in the general population, but dimensional models have not had a significant impact on our understanding of mental ill-health and problem behaviours experienced by adults with intellectual disabilities. This paper systematically reviews the methods and findings from intellectual disabilities studies that use statistical methods to identify dimensions of psychopathology from data collected using structured assessments of psychopathology. The PRISMA framework for systematic review was used to identify studies for inclusion. Study methods were compared to best-practice guidelines on the use of exploratory factor analysis. Data from the 20 studies included suggest that it is possible to use statistical methods to model dimensions of psychopathology experienced by adults with intellectual disabilities. However, none of the studies used methods recommended for the analysis of non-continuous psychopathology data and all 20 studies used statistical methods that produce unstable results that lack reliability. Statistical modelling is a promising methodology to improve our understanding of mental ill-health experienced by adults with intellectual disabilities but future studies should use robust statistical methods to build on the existing evidence base.

A qualitative study exploring why adults with intellectual disabilities and obesity want to lose weight and views of their carers

Background

Obesity is more prevalent in adults with intellectual disabilities (ID) compared to the general population. Motivations for weight loss may influence engagement with weight management programmes and have only been studied in adults without ID. Aims: To determine reasons given by adults with ID and obesity for seeking weight loss and whether these reasons differ from those of their carers.

Methods

Prior to a multi-component weight management intervention, participants were asked “why do you want to lose weight?” Carers were asked their views and these were compared to the answers given by the adult with ID. Responses were themed. The Fisher’s Exact analysis was used to test for any relationship between reasons for seeking weight loss and participants’ level of ID, age, gender and BMI.

Results

Eighteen men and 32 women; age 41.6 SD 14.6 years; BMI 40.8 SD 7.5 kg/m²; Level ID Mild (28 %), Moderate (42 %), Severe (22 %), Profound (8 %). Eleven were unable to respond. Six themes emerged; Health; Fitness / Activity / Mobility; Appearance / Clothes; Emotional / Happiness; For Others; Miscellaneous. The most frequent reason given overall and by women was “appearance.” Carers cited “health” most frequently and “appearance” least, rarely agreeing with participants. “Health” was given as a reason more from older adults and those with milder ID. No statistically significant associations were found between reasons for seeking weight loss and BMI age, gender or level of ID but the differing views of adults with ID and their carers were clear.

Conclusions

Views of adults with obesity and mild or moderate ID can be collected. The opposing views of adults and their carers may affect motivation for weight loss.

A feasibility study of behavioural activation for depressive symptoms in adults with intellectual disabilities

BACKGROUND

Important work has been carried out adapting cognitive behavioural therapy for people with intellectual disabilities. However, there is a lack of alternative psychological therapies available for people with intellectual disabilities and emotional difficulties. Behavioural activation for depression is less reliant on verbal communication and focuses on increasing purposeful activity and reducing avoidance.

METHOD

This feasibility study involved the development and piloting of an adapted manual of behavioural activation for people with intellectual disabilities. The intervention consisted of 10-12 sessions and a key adaptation was that the therapist worked with the clients alongside a significant other in their life, either a paid carer or family member. Baseline, post-intervention (3 months after entering the study) and 6-month quantitative follow-up data were obtained. Primary outcome data were gathered, concerning depressive symptoms, participants' levels of activity and general well-being.

RESULTS

Twenty-three adults with intellectual disabilities with symptoms of depression were recruited from specialist health services. In terms of acceptability, the behavioural activation intervention was well received and only two individuals dropped out, with a further two lost to follow-up. The main measures of depression appeared to be sensitive to change. Pre- to post-intervention data showed a significant reduction in self-report of depressive symptoms with a strong effect size (r = 0.78), that was maintained at follow-up (r = 0.86). Positive change was also obtained for informant reports of depressive symptoms from pre- to post-intervention, with a strong effect size (r = 0.7). Once again, this positive change was maintained at follow-up (r = 0.72).

CONCLUSIONS

The study suggested that behavioural activation may be a feasible and worthwhile approach to tackling depression in people with intellectual disabilities. However, a randomised controlled trial would be required to establish its effectiveness, with more sensitive measurement of change in activity.

Effectiveness of a walking programme to support adults with intellectual disabilities to increase physical activity: walk well cluster-randomised controlled trial

BACKGROUND

Programs to change health behaviours have been identified as one way to reduce health inequalities experienced by disadvantaged groups. The objective of this study was to examine the effectiveness of a behaviour change programme to increase walking and reduce sedentary behaviour of adults with intellectual disabilities.

METHODS

We used a cluster randomised controlled design and recruited participants over 18 years old and not regularly involved in physical activity from intellectual disabilities community-based organisations. Assessments were carried out blind to allocation. Clusters of participants were randomly allocated to the Walk Well program or a 12-week waiting list control. Walk Well consisted of three face-to-face physical activity consultations incorporating behaviour change techniques, written resources for participants and carers, and an individualised, structured walking programme. The primary outcome measured with accelerometers was change in mean step count per day between baseline and 12 weeks. Secondary outcomes included percentage time per day sedentary and in moderate-vigorous physical activity (MVPA), body mass index (BMI), and subjective well being.

RESULTS

One hundred two participants in 50 clusters were randomised. 82 (80.4%) participants completed the primary outcome. 66.7% of participants lived in the most deprived quintile on the Scottish Index of Multiple Deprivation. At baseline, participants walked 4780 (standard deviation 2432) steps per day, spent 65.5% (standard deviation 10.9) of time sedentary and 59% percent had a body mass in the obesity range. After the walking programme, the difference between mean counts of the Walk Well and control group was 69.5 steps per day [95% confidence interval (CI) -1054 to 1193.3]. There were no significant between group differences in percentage time sedentary 1.6% (95% CI -2.984 to 6.102), percentage time in MVPA 0.3% (95% CI -0.7 to 1.3), BMI -0.2 kg/m(2) (95% CI -0.8 to 0.4) or subjective well-being 0.3 (95% CI -0.9 to 1.5).

CONCLUSIONS

This is the first published trial of a walking program for adults with intellectual disabilities. Positively changing physical activity and sedentary behaviours may require more intensive programmes or upstream approaches to address the multiple social disadvantages experienced by adults with intellectual disabilities. Since participants spent the majority of their time sedentary, home-based programmes to reduce sitting time may be a viable health improvement approach.

Feasibility of a laboratory-based accelerometer calibration protocol for children with intellectual disabilities

BACKGROUND

Accelerometry has not been calibrated for the estimation of physical activity in children with intellectual disabilities (ID), raising questions regarding the validity of interpreting accelerometer data in this population. Various protocols and criterion measures have been used in calibration studies involving typically developing (TD) children; however, the suitability of these activities and measures for children with ID is unknown. Therefore, this study aimed to test the feasibility of a laboratory-based calibration protocol for children with ID. Specifically, the feasibility of activities, measurements, and recruitment was investigated.

METHODS

Five children with mild to moderate ID (10.20 ± .98 years) and a comparative sample of five TD children (12.40 ± .01 years) participated in this study. Participants performed a free-living and treadmill-based activity protocol during two laboratory-based sessions. Activities were performed for 5 min and ranged from sedentary to vigorous intensity. Treadmill activities ranged from 3 to 8 km/h, and free-living activities included watching a DVD, passing a football, and jumping jacks. Resting energy expenditure was measured, and a graded exercise test was used to assess cardiorespiratory fitness. Breath-by-breath respiratory gas exchange and accelerometry were continually measured during all activities. Feasibility was assessed using observations, activity completion rates, and respiratory data.

RESULTS

All TD participants and one participant with ID completed the protocol. The physical demands of the treadmill activities affected the completion rate for participants with ID. No participant met the maximal criteria for the graded exercise test or attained a steady state during the resting measurements. Limitations were identified with the usability of respiratory gas exchange equipment and the validity of measurements. The school-based recruitment strategy was not effective, with a participation rate of 6 %. A significant (z = 13.21, p < .0001) difference in the relationship of [Formula: see text] and accelerometry was identified between ID and TD participants.

CONCLUSIONS

Due to issues with the usability and validity of breath-by-breath respiratory gas exchange and recruitment, a laboratory-based calibration protocol is currently not feasible for children with ID. An alternative field-based protocol with a non-invasive criterion measure should be considered for future studies.

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.

Practice nurse health checks for adults with intellectual disabilities: a cluster-design, randomised controlled trial

BACKGROUND

Adults with intellectual disabilities have substantial health inequalities and poor access to health care. We assessed whether practice nurse-delivered health checks could improve the health of adults with intellectual disabilities compared with standard care.

METHODS

In this cluster-design, single-blind, randomised controlled trial, we included general practices in Scotland, UK. From June to December, 2011, we randomly assigned (1:1) these general practices to either health checks plus standard care (health-checks group), or standard care only (control group), and we recruited the patients from these practices. Randomisation was done with stratification by number of GPs per practice and number of registered patients with intellectual disabilities (<20 or ≥20). Two research assistants were masked to allocation, and undertook the review of 9 month medical records and interviews. Participants and carers were not masked. The intervention was one health check designed especially for people with intellectual disabilities delivered by a practice nurse. The objective was improvement in health and health care 9 months after randomisation, and the primary outcome was the incidence of newly detected health needs being met by this timepoint. Whether needs were met was established by the investigators being masked to group allocation. The analysis was by intention to treat. This trial is registered with Current Controlled Trials, number ISRCTN43324841.

FINDINGS

Between June 26 and Dec 20, 2011, we recruited 38 practices. 85 participants (from 16 practices) were randomly assigned to intervention and 67 (from 17 practices) to standard care; five of the identified practices did not supply any participants. 83 intervention and 66 standard care participants completed the trial. More newly detected health needs were met in the intervention group than in the control standard care group (median 1 [range 0-8], 76·4% met [SD 36·5] vs 2 [0-11], 72·6% met [35·4]; odds ratio [OR] 1·73 [95% CI 0·93-3·22], p=0·085), although this difference was not significant. Significantly more health monitoring needs were met in the intervention group than standard care (median 2 [0-20], 69·9% [SD 34·2] vs 2 [0-22], 56·8% [29·4], OR 2·38 [95% CI 1·31-4·32, p=0·0053]). The probability that health checks are cost effective was between 0·6 and 0·8, irrespective of the cost-effectiveness threshold level. Costs per patient were -£71·48 for health checks and -£20·56 for standard care. The difference (-£50·92) was not significant [95% CI -434 to 362]. No adverse events were attributable to the intervention.

INTERPRETATION

Health checks given by practice nurses to adults with intellectual disabilities produced health-care improvements that were more conducive to longer-term health than standard care given to this population. The intervention dominated standard care, being both cheaper and more effective. Health-check programmes might therefore be indicated for adults with intellectual disabilities.

Accelerometer use during field-based physical activity research in children and adolescents with intellectual disabilities: a systematic review

Many methodological questions and issues surround the use of accelerometers as a measure of physical activity during field-based research. To ensure overall research quality and the accuracy of results, methodological decisions should be based on study research questions. This paper aims to systematically review accelerometer use during field-based research in children and adolescents with intellectual disabilities. Medline, Embase, Cochrane Library, Web of Knowledge, PsycINFO, PubMed, and a thesis database (up to May 2013) were searched to identify relevant articles. Articles which used accelerometry-based monitors, quantified activity levels, and included ambulatory children and adolescents (≤ 18 years) with intellectual disabilities were included. Based on best practice guidelines, a form was developed to extract data based on 17 research components of accelerometer use. The search identified 429 articles. Ten full-text articles met the criteria and were included in the review. Many shortcomings in accelerometer use were identified, with the percentage of review criteria met ranging from 12% to 47%. Various methods of accelerometer use were reported, with most use decisions not based on population-specific research. However, a lack of measurement research, e.g., calibration/validation, for children and adolescents with intellectual disabilities is limiting the ability of field-based researchers to make to the most appropriate accelerometer use decisions. The methods of accelerometer use employed can have significant effects on the quality and validity of results produced, which researchers should be more aware of. To allow informed use decisions, there should be a greater focus on measurement research related to children and adolescents with intellectual disabilities.

Carers' perspectives of a weight loss intervention for adults with intellectual disabilities and obesity: a qualitative study

BACKGROUND

To date, no studies have explored the role of carers in supporting adults with intellectual disabilities (ID) and obesity during a weight loss intervention. The present study explored perceptions of carers supporting adults with ID, as they participated in a 6-month multi-component weight loss intervention (TAKE 5).

METHODS

Semi-structured interviews were used to explore the experiences of 24 carers. The transcripts were analysed qualitatively using thematic analysis.

RESULTS

Three themes emerged from the analysis: carers' perceptions of participants' health; barriers and facilitators to weight loss; and carers' perceptions of the weight loss intervention. Data analysis showed similarities between the experiences reported by the carers who supported participants who lost weight and participants who did not. Lack of sufficient support from people from the internal and external environment of individuals with ID and poor communication among carers, were identified as being barriers to change. The need for accessible resources tailored to aid weight loss among adults with ID was also highlighted.

CONCLUSION

This study identified specific facilitators and barriers experienced by carers during the process of supporting obese adults with ID to lose weight. Future research could utilise these findings to inform appropriate and effective weight management interventions for individuals with ID.

Clinical guidelines contribute to the health inequities experienced by individuals with intellectual disabilities

BACKGROUND

Clinical practice guidelines are developed to improve the quality of healthcare. However, clinical guidelines may contribute to health inequities experienced by disadvantaged groups. This study uses an equity lens developed by the International Clinical Epidemiology Network (INCLEN) to examine how well clinical guidelines address inequities experienced by individuals with intellectual disabilities.

METHODS

Nine health problems relevant to the health inequities experienced by persons with intellectual disabilities were selected. Clinical guidelines on these disorders were identified from across the world. The INCLEN equity lens was used as the basis for a purpose-designed, semistructured data collection tool. Two raters independently examined each guideline and completed the data collection tool. The data extracted by each rater were discussed at a research group consensus conference and agreement was reached on a final equity lens rating for each guideline.

RESULTS

Thirty-six guidelines were identified, one of which (2.8%) explicitly excluded persons with intellectual disabilities. Of the remaining 35, six (17.1%) met the first criterion of the equity lens, identifying persons with intellectual disabilities at high risk for the specific health problem. Eight guidelines (22.9%) contained any content on intellectual disabilities. Six guidelines addressed the fourth equity lens criterion, by giving specific consideration to the barriers to implementation of the guideline in disadvantaged populations. There were no guidelines that addressed the second, third, and fifth equity lens criteria.

CONCLUSIONS

The equity lens is a useful tool to systematically examine whether clinical guidelines address the health needs and inequities experienced by disadvantaged groups. Clinical guidelines are likely to further widen the health inequities experienced by persons with intellectual disabilities, and other disadvantaged groups, by being preferentially advantageous to the general population. There is a need to systematically incorporate methods to consider disadvantaged population groups into the processes used to develop clinical guidelines.

Agreement of accelerometer and a physical activity questionnaire in adults with intellectual disabilities

PURPOSE

To assess the level of agreement between accelerometer and proxy-respondent questionnaire measurement of the physical activity levels of adults with intellectual disabilities.

METHODS

In Glasgow, U.K., from May to September 2009, the main carer of participants with intellectual disabilities was asked to complete the International Physical Activity Questionnaire-Short Version, detailing the participants' regular physical activity levels. Participants were also invited to wear an ActiGraph GT1M accelerometer for seven consecutive days, during all waking hours. The level of agreement from the two measurements was compared using the Bland-Altman method.

RESULTS

There is limited agreement between physical activity and sedentary behavior measured with accelerometer and proxy-respondent questionnaire. The 95% limits of agreement for both moderate activity and sedentary activity were -44.48 to 34.20 min per day and -8.41 to 6.79 h per day, respectively. As physical activity increased above 10 min per day, the agreement between the accelerometer and International Physical Activity Questionnaire-Short Version data decreased further.

CONCLUSION

It remains uncertain whether questionnaire methods have sufficient reliability for use in surveillance of physical activity levels of adults with intellectual disabilities.

A review of weight loss interventions for adults with intellectual disabilities

Obesity is more prevalent in adults with intellectual disabilities than in the general population, and has been shown to contribute to their reduced life expectancy, and increased health needs. Relatively few studies have examined the effectiveness of weight loss interventions for adults with intellectual disabilities. However, there is evidence to support interventions that take account of the context of the lives of adults with intellectual disabilities, including carer involvement in interventions. To reduce the health inequalities experienced by adults with intellectual disabilities, there is a clear need to develop accessible, evidence-based clinical weight management services.

The prevalence and determinants of obesity in adults with intellectual disabilities

People with intellectual disabilities experience significant health inequalities compared with the general population, including a shorter life expectancy and high levels of unmet health needs. Another accepted measure of health inequalities, the prevalence of obesity, has been shown to be higher in adults with intellectual disabilities than in the general population. While the factors contributing to the increased prevalence among adults with intellectual disabilities are not well understood, the high rates of obesity among younger adults highlight the need for further research involving children and adolescents with intellectual disabilities. To take forward the priorities for research and the development of effective, accessible services, there is a need for collaboration between professionals working in the fields of intellectual disabilities and obesity.

The outcomes of an intervention study to reduce the barriers experienced by people with intellectual disabilities accessing primary health care services

BACKGROUND

People with intellectual disabilities (IDs) experience significant health inequalities compared with the general population. The barriers people with IDs experience in accessing services contribute to these health inequalities. Professionals' significant unmet training needs are an important barrier to people with IDs accessing appropriate services to meet their health needs.

METHOD

A three group, pre- and post-intervention design was used to test the hypothesis that a training intervention for primary health care professionals would increase the knowledge and self-efficacy of participants. The intervention had two components - a written training pack and a 3-hour face-to-face training event. One group received the training pack and attended the training event, a second group received the training pack only, and a third group did not participate in the training intervention. Research measures were taken prior to the intervention and 3 months after the intervention. Statistical comparisons were made between the three groups.

RESULTS

The participants in the training intervention reported that it had a positive impact upon their knowledge, skills and clinical practice. As a result of the intervention, 35 (81.4%) respondents agreed that they were more able to meet the needs of their clients with IDs, and 33 (66.6%) reported that they had made changes to their clinical practice. The research demonstrated that the intervention produced a statistically significant increase in the knowledge of participants (F = 5.6, P = 0.005), compared with the group that did not participate in the intervention. The self-efficacy of the participants that received both components of the intervention was significantly greater than the group that did not participate in the training (t = 2.079, P = 0.04). Participation in the two components of the training intervention was associated with significantly greater change in knowledge and self-efficacy than those receiving the training pack alone.

CONCLUSION

This intervention was effective in addressing the measured training needs of primary health care professionals. Future research should directly evaluate the positive benefits of interventions on the lives of people with IDs.

Enhancing primary health care services for adults with intellectual disabilities

BACKGROUND

Primary health care teams have an important part to play in addressing the health inequalities and high levels of unmet health needs experienced by people with intellectual disabilities (ID). Practice nurses have an expanding role within primary health care teams. However, no previous studies have measured their attitudes, knowledge, training needs, and self-efficacy in their work with people with ID.

METHODS

All practice nurses working in a defined area were identified. A purpose-designed questionnaire to measure nurse attitudes, knowledge, training needs and self-efficacy was developed and piloted. All practice nurses were then invited to participate. Data from completed questionnaires were entered onto PC and analysed.

RESULTS

Of a total of 292 practice nurses 201 (69%) participated. Whilst 89% (n=179) of participants reported having infrequent contact, 25% (n=50) reported a growing workload with people with ID. Only 8% (n=16) had ever received any training in communicating with people with ID. A knowledge gap regarding the health needs of people with ID was identified. Eighty-six per cent reported having experienced specific difficulties during previous appointments, and only 23% thought they had sufficient case note information at appointments, but 68% did not modify the duration of their appointments with people with ID. Conversely, responses demonstrated that practice nurses have a high level of experience and qualification in general nursing, have positive attitudes to working with people with ID, and high self-efficacy scores were identified for work with people with ID. The practice nurses viewed ID to be a high priority area for future training.

CONCLUSIONS

Primary health care teams have a key role in tackling the unmet health needs of people with ID. Whilst this project has identified factors that may impact on the accessibility of services, it has also identified practice nurses as having positive attitudes and high self-efficacy scores in their work with people with ID. This indicates that they should be targeted for specific training in this area, which may make an important contribution in enhancing future accessibility of primary health care services for people with ID.

Obesity in adults with Down syndrome: a case-control study

BACKGROUND

Obesity has a negative impact upon mortality and morbidity. Studies report that obesity is more prevalent in individuals with Down syndrome than individuals with intellectual disabilities (ID) not associated with Down syndrome. However, there have been no studies using a methodology of matched comparison groups and findings from previous studies are contradictory.

METHODS

A detailed method was used to identify all adults with ID in Leicestershire. Individuals were invited to participate in a medical examination - that included measurement of their height and weight, from which body mass index (BMI) was calculated. For each person with Down syndrome, an individual matched for gender, age and accommodation type was identified, from the Leicestershire ID database.

RESULTS

The data for 247 matched pairs is reported. Women with Down syndrome had lower mean height and weight, but greater mean BMI than the matched pairs. Men with Down syndrome had a lower mean height and weight but there was no statistical difference in BMI compared to the matched pairs. Using World Health Organization categories of BMI, women with Down syndrome were more likely to be overweight or obese than their matched pairs (odds ratio = 2.17). Men with Down syndrome were more likely to be in the overweight category than their matched pairs but were less likely to be obese (odds ratio = 0.85).

CONCLUSIONS

This study demonstrates that, compared to a matched sample, there is a greater prevalence of obesity amongst women with Down syndrome but not men. As the impact on the health of people with Down syndrome of being overweight or obese is uncertain, this is an area that requires further study.

A critique of the Diagnostic Criteria for Psychiatric Disorders for Use with Adults with Learning Disabilities/Mental Retardation (DC-LD) chapter on non-affective psychotic disorders

BACKGROUND

There has been a longstanding interest in the study of psychotic disorders in adults with intellectual disability. The DC-LD chapter for non-affective psychotic disorders provides operationalised criteria for use with this population.

METHODS

A detailed, structured review of the literature was carried out. Relevant papers were reviewed to provide a framework for a critique of the DC-LD criteria.

RESULTS

Most of the research literature focuses on psychotic disorders in adults with mild intellectural disability and suggests that this group experience clinical symptoms similar to those experienced by adults with average abilities. Although the DC-LD criteria for non-affective psychotic disorders are derived from the ICD-10 equivalent categories they are broader than other classification systems, which may affect their reliability, validity and utility.

CONCLUSIONS

At this stage, it is important that the DC-LD criteria are used alongside established systems to gather information about their use for clinical and research purposes.

Psychiatric diagnosis, intellectual disabilities and Diagnostic Criteria for Psychiatric Disorders for Use with Adults with Learning Disabilities/Mental Retardation (DC-LD)

BACKGROUND

Classification of psychopathology using operationalized diagnostic criteria is one component of psychiatric assessment. Previous literature has demonstrated that there are limitations in the International Classification of Diseases-10 (ICD-10) and the Diagnostic and Statistical Manual-IV (DSM-IV) when used with adults with intellectual disabilities.

METHODS

A literature search using Medline, PsychLIT and hand searching of key journals identified the existing literature, which was reviewed by the Diagnostic Criteria for Psychiatric Disorders for Use with Adults with Learning Disabilities/Mental Retardation (DC-LD) Development Working Group. Key findings are integrated into this paper. This, together with expert consensus led to the development of DC-LD, a new psychiatric classificatory system devised specifically for use with adults with intellectual disabilities. The new diagnostic criteria and classification within DC-LD were piloted with 52 field investigators drawing on 709 clinical cases. Validity of DC-LD classification was measured by comparison between the criteria providing DC-LD diagnosis and the gold standard of learning disabilities psychiatric assessment.

RESULTS

In 96.3% of cases, the DC-LD diagnosis was fully concordant with that of clinical opinion. The few discrepancies related to level of detail.

CONCLUSION

DC-LD accommodates the pathoplastic effect of intellectual disabilities on psychopathology. Its use will hopefully improve clinical practice and facilitate research, but further work to determine its usefulness and limitations is required.

Counting the cost: hospital versus home central venous catheter survival

We compared catheter survival and sepsis rates in a tertiary paediatric gastroenterology centre with those at home in the same patients. We examined whether there were differences in the safety in the two locations, and estimated the financial and opportunity cost implications of any difference. We used survival analysis to analyse differences. Surgical records were audited to determine venous access workload, and to estimate cost implications. Twenty patients with chronic intestinal failure but stable parenteral nutrition requirements, ranging from 0.04-15.83 years of age were studied. The duration of line survival and sepsis-free intervals and rates of re-operation for venous access were determined to estimate morbidity and costs. The study encompassed 28 patient-years in hospital and 48 patient-years at home. There was a significant reduction in the rate of sepsis at home compared with hospital (Z = 4.30, P < 0.00001), and a similar improvement in line survival (Z = 4.36, P < 0.00001). Line insertions accounted for 21% of minor surgery in our hospital, one third being reinsertions. We conclude that central venous catheter sepsis rates are greatly improved at home. If home results could be achieved in the hospital setting, considerable cost savings would be made.
