Background: Adults with intellectual disabilities (IDs) are susceptible to multiple health risk behaviours such as alcohol consumption, smoking, low physical activity, sedentary behaviour and poor diet. Lifestyle modification interventions can prevent or reduce negative health consequences caused by these behaviours. We aim to determine the effectiveness of lifestyle modification interventions and their components in targeting health risk behaviours in adults with IDs. Methods: A systematic review and meta‐analysis were conducted. Electronic databases, clinical trial registries, grey literature and citations of systematic reviews and included studies were searched in January 2021 (updated February 2022). Randomised controlled trials and non‐randomised controlled trials targeting alcohol consumption, smoking, low physical activity, sedentary behaviours and poor diet in adults (aged ≥ 18 years) with ID were included. Meta‐analysis was conducted at the intervention level (pairwise and network meta‐analysis) and the component‐level (component network meta‐analysis). Studies were coded using Michie's 19‐item theory coding scheme and 94‐item behaviour change taxonomies. Risk of bias was assessed using the Cochrane Risk of Bias (ROB) Version 2 and Risk of Bias in Non‐randomised Studies of Interventions (ROBINS‐I). The study involved a patient and public involvement (PPI) group, including people with lived experience, who contributed extensively by shaping the methodology, providing valuable insights in interpreting results and organising of dissemination events. Results: Our literature search identified 12 180 articles, of which 80 studies with 4805 participants were included in the review. The complexity of lifestyle modification intervention was dismantled by identifying six core components that influenced outcomes. Interventions targeting single or multiple health risk behaviours could have a single or combination of multiple core‐components. Interventions (2 RCTS; 4 non‐RCTs; 228 participants) targeting alcohol consumption and smoking behaviour were effective but based on limited evidence. Similarly, interventions targeting low physical activity only (16 RCTs; 17 non‐RCTs; 1413 participants) or multiple behaviours (low physical activity only, sedentary behaviours and poor diet) (17 RCTs; 24 non‐RCTs; 3164 participants) yielded mixed effectiveness in outcomes. Most interventions targeting low physical activity only or multiple behaviours generated positive effects on various outcomes while some interventions led to no change or worsened outcomes, which could be attributed to the presence of a single core‐component or a combination of similar core components in interventions. The intervention‐level meta‐analysis for weight management outcomes showed that none of the interventions were associated with a statistically significant change in outcomes when compared with treatment‐as‐usual and each other. Interventions with core‐components combination of energy deficit diet, aerobic exercise and behaviour change techniques showed the highest weight loss [mean difference (MD) = −3.61, 95% credible interval (CrI) −9.68 to 1.95] and those with core‐components combination dietary advice and aerobic exercise showed a weight gain (MD 0.94, 95% CrI −3.93 to 4.91). Similar findings were found with the component network meta‐analysis for which additional components were identified. Most studies had a high and moderate risk of bias. Various theories and behaviour change techniques were used in intervention development and adaptation. Conclusion: Our systematic review is the first to comprehensively explore lifestyle modification interventions targeting a range of single and multiple health risk behaviours in adults with ID, co‐produced with people with lived experience. It has practical implications for future research as it highlights the importance of mixed‐methods research in understanding lifestyle modification interventions and the need for population‐specific improvements in the field (e.g., tailored interventions, development of evaluation instruments or tools, use of rigorous research methodologies and comprehensive reporting frameworks). Wide dissemination of related knowledge and the involvement of PPI groups, including people with lived experience, will help future researchers design interventions that consider the unique needs, desires and abilities of people with ID.

Background: Lifestyle modification interventions for adults with intellectual disabilities have had, to date, mixed effectiveness. This study aimed to understand how lifestyle modification interventions for adults with intellectual disabilities work, for whom they work and in what circumstances. Methods: A realist evidence synthesis was conducted that incorporated input from adults with intellectual disabilities and expert researchers. Following the development of an initial programme theory based on key literature and input from people with lived experience and academics working in this field, five major databases (MEDLINE, EMBASE, CINAHL, PsycINFO and ASSIA) and clinical trial repositories were systematically searched. Data from 79 studies were synthesised to develop context, mechanism and outcome configurations (CMOCs). Results: The contexts and mechanisms identified related to the ability of adults with intellectual disabilities to actively take part in the intervention, which in turn contributes to what works, for whom and in what circumstances. The included CMOCs related to support involvement, negotiating the balance between autonomy and behaviour change, fostering social connectedness and fun, accessibility and suitability of intervention strategies and delivery and broader behavioural pathways to lifestyle change. It is also essential to work with people with lived experiences when developing and evaluating interventions. Conclusions: Future lifestyle interventions research should be participatory in nature, and accessible data collection methods should also be explored as a way of including people with severe and profound intellectual disabilities in research. More emphasis should be given to the broader benefits of lifestyle change, such as opportunities for social interaction and connectedness. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Background: The promotion of physical activity and the decrease of inactivity and sedentary behaviour are crucial for a healthy lifestyle and positive quality of life. People with intellectual disabilities are at increased risk of inactivity and sedentary behaviour. Therefore, it is important to increase their physical activity by implementing physical activity guidelines in their daily life. Professional direct care providers can play a decisive role in supporting people with intellectual disabilities to participate in physical activity, but the engagement of direct care providers with this role may be reflective of their own attitudes and beliefs towards physical activity. Therefore, the link between the implementation of current physical activity guidelines for people with intellectual disabilities and direct care providers' own beliefs and behaviour with regard to physical activity is investigated. Method: A total of 104 direct care providers completed self‐reported questionnaires about their own physical activity behaviour (IPAQ‐SF), recommendations for people with intellectual disabilities (adaption of EMIQ‐HP) and questions regarding global physical activity guidelines. They were also asked about potential barriers and facilitators for the recommendation of physical activity in open‐ended questions. Results: Personal physical activity behaviour is related to the recommended physical activity for people with intellectual disabilities (moderate‐to‐vigorous physical activity: rs = 0.408, P = 0.005). However, recommended physical activity behaviour for people with intellectual disabilities is significantly lower than direct care providers' own physical activity behaviour (P < 0.001). 47.1% of the respondents recommended people with intellectual disabilities to participate in less than the 150 min of moderate intensity physical activity per week for that is recommended in global physical activity guidelines. Conclusion: Direct care providers may hold stereotypical views and insecurities about the potential harms associated with people with intellectual disabilities participating in physical activity. Therefore, the dissemination of physical activity recommendations for people with intellectual disabilities should be a major target for health professionals, social workers and scientists to address direct care providers' concerns. Furthermore, we need to emphasise the benefits of regular physical activity to professional direct care providers and directly to people with intellectual disabilities. [ABSTRACT FROM AUTHOR]

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.

Abstract: 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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

The aim of this study was to examine the literature on randomized controlled trials examining the efficacy of physical activity interventions to prevent weight gain and the effects on body composition in young adults with intellectual disabilities.A systematic search of Medline, Emabse, CINHAL, PsychINFO, Cochrane library and ERIC was conducted from 1946 to September 2014. Eligibility criteria included; randomized controlled trials of a physical activity intervention: objective measure of body weight and body composition; young adults (age range 16-24 years) with intellectual disabilities. Six studies met the eligibility criteria. The interventions varied in their prescription of physical activity including aerobic and strength-based activities. The mean duration of the interventions was 15.3 (range 10-21 weeks). There was no significant effect of physical activity interventions on body weight (weighted mean difference: −0.17 kg, 95% confidence interval, −1.04 kg to 0.72 kg) and body composition outcomes. The meta-analysis showed that physical activity interventions did not prevent weight gain in young adults with intellectual disabilities. Published studies are inadequate to form firm conclusions. Future longer term studies of interventions specifically designed for this population group are required to elucidate the effects of physical activity interventions on body composition and the prevention of weight gain in young adults with intellectual disabilities.
