Weight management for adolescents with intellectual and developmental disabilities: Rationale and design for an 18month randomized trial

Motivation in caregiving among mothers of children with intellectual and developmental disabilities in Iran: A qualitative study

BACKGROUND

The motivation of caregivers plays a crucial role in the treatment, follow-up, and care of children with intellectual and developmental disabilities. Previous studies have focused on the older people and end-stage diseases, while giving less attention to the motivation of mothers caring for children with special needs. This study aimed to explore the motivations of mothers caring for children with intellectual and developmental disabilities in Iran.

METHODS

This study employed a qualitative approach, guided by the Self-Determination Theory. Purposeful sampling was initially used, followed by theoretical sampling until data saturation was achieved. Data were collected through semi-structured interviews with 26 mothers of children with intellectual and developmental disabilities. Mayring's seven-step directed content analysis approach was utilized for coding and categorization. The research adhered to ethical standards and ensured data trustworthiness through credibility, dependability, confirmability, and transferability measures.

RESULTS

The findings revealed that mothers' caregiving motivations could be classified into four main categories: (I) intrinsic, (II) identified-extrinsic, (III) introjected-extrinsic, and (IV) external-extrinsic. Additionally, twelve sub-categories were identified within these four main categories.

CONCLUSION

The findings revealed that mothers demonstrated varying levels of intrinsic and extrinsic motivations in caring for children with intellectual and developmental disabilities. By recognizing and enhancing the diverse sources of motivation, healthcare providers and policymakers can better support mothers in their caregiving roles, ultimately contributing to improved outcomes for both the mothers and their children.

A Remotely Delivered Yoga Intervention for Adolescents with Autism Spectrum Disorder: Feasibility and Effectiveness for Improving Skills Related to Physical Activity

This study evaluated the feasibility of remotely delivered yoga for improving four physical activity-related skills: motor skills, strength, balance, and flexibility in adolescents with autism spectrum disorder (ASD). Nineteen of 20 participants enrolled (age 13.2 ± 2.2 years; 60% male) completed the 12-week intervention and attended 83% of the scheduled yoga sessions. Overall, physical activity-related skills improved pre to post intervention (Φ = 0.90, p = 0.005, 95% CI 0.72-1.0). Specifically, significant increases in leg strength (12.5%, p = 0.039), flexibility (40.3%, p = 0.008), and dynamic balance on the right (11.1%, p = 0.001) and left legs (8.1%, p = 0.003) were observed across 12 weeks. These results demonstrate the feasibility and potential effectiveness of yoga to improve physical activity-related skills in adolescents with ASD.

Parent factors associated with BMI, diet, and physical activity of adolescents with intellectual and developmental disabilities

BACKGROUND

Adolescents with intellectual and developmental disabilities (IDD) experience overweight and obesity (OW/OB) up to 1.8 times the rate of their typically developing peers. Parents may influence adolescent weight management behaviors in this population, but the association between parent factors and adolescent weight management behaviors is unclear.

OBJECTIVE

To examine the associations between parent BMI and sociodemographic characteristics with adolescents' BMI, diet quality, daily energy intake, moderate to vigorous physical activity (MVPA), and sedentary behavior.

METHODS

This study analyzed baseline data from an 18-month randomized controlled weight loss trial for adolescents with IDD. We assessed parent BMI (kg/m2) and sociodemographic factors, and adolescent BMI z-score, MVPA, sedentary time, daily energy intake, and diet quality. Associations between parent and adolescent factors were assessed with Pearson, Spearman or Kendall Tau-b correlations; mean differences for categorical outcomes were assessed with independent samples t-tests/Mann-Whitney U tests or ANOVA/Kruskall-Wallis tests.

RESULTS

Ninety-five adolescent and parent dyads were included. Parent BMI was positively correlated with adolescent BMI z-score (n = 94: rs = 0.37, p < 0.01). Household income was inversely correlated with adolescent BMI z-score (n = 95: Tb = -0.18, p = 0.02). Parents with less than a bachelor's degree had adolescents with higher BMI z-scores than those with bachelor's or higher (2.1 ± 0.5 vs. 1.8 ± 0.5, p = 0.02) as well as higher sedentary behavior (n = 28, 515.2 ± 102.6 min/day vs. n = 40, 463.9 ± 148.1 min/day, p = 0.02).

CONCLUSION

We found parent BMI, income, and education associated with adolescent BMI z-score. These findings contribute to the sparse literature on parental factors associated with OW/OB in this population.

The prevalence of obesity and lifestyle behaviors of parents of youth with intellectual and developmental disabilities

BACKGROUND

Parents of youth with intellectual and developmental disabilities (IDD) may have a higher prevalence of overweight and obesity and poorer weight management behaviors compared to the general population.

OBJECTIVE

To describe the prevalence of overweight/obesity and related socioeconomic and lifestyle factors including diet quality, physical activity, and reported health habits in parents of youth with IDD.

METHODS

We assessed: BMI (kg/m2), moderate-to-vigorous physical activity (MVPA), fruit and vegetable intake (FVI), parental diet and physical activity habits, and socioeconomic characteristics. Associations of BMI on MVPA and FVI were assessed with Spearman's correlation; differences in BMI by parental diet and physical activity habits were assessed with Kruskall-Wallis tests; and the relationships of BMI to household income, race, and education were assessed with Kendall Tau-b and Mann Whitney U tests.

RESULTS

Data was obtained from 110 parents (97.3% female) who were study partners for their adolescents/young adults with IDD participating in a weight loss clinical trial. Approximately 81% of parents were overweight or obese (25.7% overweight, 55.1% obese), with 46.3% and 20% meeting the recommended U.S. guidelines for MVPA and FVI, respectively. Higher FVI and higher income were significantly associated with lower parent BMI. BMI was significantly lower in parents who reported to be physically active and choose healthy food.

CONCLUSION

We observed a high prevalence of overweight/obesity, low FVI and low levels of MVPA in parents of adolescents with IDD. These observations suggest that interventions designed to address these factors have the potential to improve the health and wellbeing of both parents and adolescents with IDD.

Interviews with parents of adolescents with intellectual and developmental disabilities in a weight management study

BACKGROUND

Adolescents and young adults with intellectual and developmental disabilities are at risk of obesity. Parents influence their diet and physical activity behaviours and therefore, can play important roles in weight management. The aims of this qualitative study were to explore parents' experiences assisting their son or daughter to participate in a weight management study.

METHODS

Interviews were completed at 6 months with 27 parents whose adolescent or young adult had completed the weight loss portion of an 18-month weight management study. Interviews were recorded, transcribed and thematic analysis performed.

RESULTS

Parents shared insights about how well program components worked with their family, and what strategies worked best to adopt healthier dietary choices and become more physically active. The importance of meeting regularly with someone outside the family to encourage healthier habits was stressed.

CONCLUSIONS

Future weight management studies should involve parents and their adolescents to help tailor strategies and adapt intervention approaches.

Resting energy expenditure in adolescents with Down syndrome: a comparison of commonly used predictive equations

BACKGROUND

Adolescents with Down syndrome (DS) are two to three times more likely to be obese than their typically developing peers. When preventing or treating obesity, it is useful for clinicians to understand an individual's energy intake needs. Predictive resting energy expenditure (REE) equations are often recommended for general use in energy intake recommendations; however, these predictive equations have not been validated in youth with DS. The aim of this study was to compare the accuracy of seven commonly used predictive equations for estimating REE in adolescents who are typically developing to REE measured by indirect calorimetry in adolescents with DS.

METHODS

Adolescents with DS participated in a 90-min laboratory visit before 10:00 a.m. after a 12-h overnight fast and a 48-h abstention from aerobic exercise. REE was measured via indirect calorimetry, and estimated REE was derived using the Institute of Medicine, Molnar, Muller and World Health Organization equations. Mean differences between the measured and predicted REE for each equation were evaluated with equivalency testing, and P-values were adjusted for multiple comparisons using the Holm method.

RESULTS

Forty-six adolescents with DS (age: 15.5 ± 1.7 years, 47.8% female, 73.9% non-Hispanic White) completed the REE assessment. Average measured REE was 1459.5 ± 267.8 kcal/day, and the Institute of Medicine equations provided the most accurate prediction of REE with a 1.7 ± 11.2% (13.9 ± 170.3 kcal/day) overestimation. This prediction was not statistically different from the measured REE [P-value = 0.582; 95% confidence interval (CI): -64.5, 36.7], and the difference between the measured and predicted REE was statistically equivalent to zero (P-value = 0.024; 90% CI: -56.1, 28.3).

CONCLUSIONS

The results suggest that the Institute of Medicine equation may be useful in predicting REE in adolescents with DS. Future research should confirm these results in a larger sample and determine the utility of the Institute of Medicine equation for energy intake recommendations during a weight management intervention.

A randomized trial comparing diet and delivery strategies for weight management in adolescents with intellectual disabilities

BACKGROUND

The literature evaluating multi-component interventions for long-term weight loss in adolescents with intellectual disabilities (ID) is extremely limited.

OBJECTIVES

To compare the effectiveness of two delivery strategies, face-to-face (FTF) or remote delivery (RD), and two diets, enhanced Stop Light diet (eSLD) or conventional diet (CD) on weight change across 12 and 18 months. in response to an 18 months. weight management intervention (6 months Weight loss/12 months. Weight maintenance) in adolescents with ID.

METHODS

Adolescents with ID were randomized to one of three arms: FTF /CD, RD/CD, RD/eSLD and asked to attend individual education sessions with a health educator which were delivered during FTF home visits or remotely using video conferencing. The CD followed the US dietary guidelines. The eSLD utilized the Stop Light guide and was enhanced with portion-controlled meals. Participants were also asked to increase their physical activity (PA) and to self-monitor diet, PA and body weight across the 18-month.

INTERVENTION

RESULTS

Weight was obtained from 92(84%) and 89(81%) randomized adolescents at 12 and 18 months, respectively. Weight change across 12 months. Differed significantly by diet (RD/eSLD: -7.0% vs. RD/CD: -1.1%, p = 0.002) but not by delivery strategy (FTF/CD: +1.1% vs. RD/CD: -1.1%, p = 0.21). Weight change across 18 months. Was minimal in all intervention arms and did not differ by diet (RD/eSLD: -2.6% vs. RD/CD: -0.5%; p = 0.28) or delivery strategy (FTF/CD: +1.6% vs. RD/CD: -0.5%; p = 0.47).

CONCLUSIONS

Additional research is required to identify effective strategies to improve long-term weight loss in adolescents with ID.

Changes in physical activity across a 6-month weight loss intervention in adolescents with intellectual and developmental disabilities

BACKGROUND

Adolescents and young adults with intellectual and developmental disabilities (IDD) have high rates of obesity and low levels of physical activity. This analysis examined changes in light, moderate-to-vigorous physical activity (MVPA) and sedentary time, and the association between changes in MVPA and weight loss in adolescents and young adults with IDD and overweight and obesity participating in a 6-month multi-component weight loss intervention.

METHODS

Adolescents and young adults with IDD and overweight or obesity (body mass index ≥ 85 percentile, n = 110, age ~16 years, 52.7% female) and a parent were randomised to one of three intervention groups: face-to-face delivery/conventional reduced energy diet (n = 36), remote delivery (RD)/conventional reduced energy diet (n = 39), or RD/reduced energy enhanced stop light diet (eSLD) (n = 35.) Participants were asked to engage in 60 min/day of MVPA on 5 or more days/wk. Participants and a parent attended twice monthly education/behavioural counselling sessions with a health educator to assist participants in complying with dietary and MVPA recommendations. Education/counselling in the RD arms was delivered remotely using video conferencing, and self-monitoring of MVPA and daily steps was completed using a wireless activity tracker. Education/counselling in the face-to-face arm was delivered during home-visits and self-monitoring of MVPA and daily steps was completed by self-report using paper tracking forms designed for individuals with IDD. MVPA, light activity, and sedentary time were assessed over 7 days at baseline and 6 months using a portable accelerometer (ActiGraph wGT3x-BT).

RESULTS

Mixed modelling analysis completed using participants with valid accelerometer data (i.e. ≥4-10 h days) at baseline (n = 68) and 6 months (n = 30) revealed no significant changes in light, moderate- MVPA, or sedentary time across the 6-month intervention (all P > 0.05). Participants obtained 15.2 ± 21.5 min/day of MVPA at baseline and 19.7 ± 19.7 min/day at 6 months (P = 0.119). Mixed modelling indicated no significant effects of group (P = 0.79), time (P = 0.10), or group-by-time interaction (P = 0.21) on changes in MVPA from baseline to 6 months. Correlational analysis conducted on participants with valid accelerometer data at both baseline and 6 months (n = 24) revealed no significant associations between baseline sedentary time (r = 0.10, P = 0.40) and baseline MVPA (r = -0.22, P = 0.30) and change in MVPA across the 6-month intervention. Additionally, attendance at education/counselling sessions (r = 0.26, P = 0.22) and frequency of self-monitoring of MVPA were not significantly associated with change in MVPA from baseline to 6 months (r = 0.26, P = 0.44). Baseline MVPA (r = 0.02, P = 0.92) and change in MVPA from baseline to 6 months (r = 0.13, P = 0.30) were not associated with changes in body weight across the 6-month intervention.

CONCLUSION

We observed a non-significant increase in MVPA (30%), which was not associated with the magnitude of weight loss in a sample of adolescents and young adults with IDD who participated in a 6-month multi-component weight loss intervention. Additional strategies to increase MVPA in adolescents and young adults with IDD participating in weight loss interventions need to be developed and evaluated.

A comparison of accelerometer cut-points for measuring physical activity and sedentary time in adolescents with Down syndrome

BACKGROUND

No cut-points have been developed for youth with Down syndrome; there is concern that altered gait patterns, decreased energy expenditure and exercise capacity of individuals with Down syndrome may produce inaccurate physical activity data if accelerometer data are analyzed using cut-points from populations with typical development and other IDD diagnoses.

AIM

To compare physical activity and sedentary time across existing accelerometer cut-point methods in adolescents with Down syndrome.

METHODS

In this cross-sectional analysis, participants diagnosed with Down syndrome (n = 37; 15.5 ± 1.9 years; 57 % female) wore an accelerometer on their non-dominant hip for seven-days. Data were analyzed and compared across four physical activity intensity cut-points: Evenson, Freedson 4-MET, McGarty, and Romanizi.

OUTCOMES & RESULTS

Differences in time spent in each intensity across cut-point methods were evident for sedentary (448-615 min/day), light (72-303 min/day) and moderate-to-vigorous (12-77 min/day) activities. Between 0.0-67.6 % of the sample met the physical activity guidelines, depending on the cut-point method selected.

CONCLUSIONS & IMPLICATIONS

This study presents the wide variation of accumulated physical activity minutes when different cut-points are applied to individuals with Down syndrome. There is a critical need to establish Down syndrome-specific measures of physical activity assessment rather than applying methods developed for their peers with typical development.

WHAT THIS PAPER ADDS

This paper highlights concerns over the application of objective measurements of physical activity in youth with Down syndrome from measurement methods derived from populations with typical development. This is the first manuscript to examine this issue in a sample comprised solely of youth with Down syndrome. Results demonstrate the large variation in time spent in each activity intensity that arise due to the application of different cut-point methods.

Weight loss in adolescents with down syndrome compared to adolescents with other intellectual disabilities enrolled in an 18-month randomized weight management trial

BACKGROUND

There is limited information on the efficacy of weight management interventions in adolescents with Down Syndrome (DS).

OBJECTIVE

To compare weight change and intervention compliance between adolescents with DS compared to adolescents with non-DS related intellectual disabilities (ID) who were enrolled in an 18-month weight management trial.

METHODS

Participants were adolescents (13-21 years) with mild to moderate ID and overweight or obesity. Participants were randomized in a 1:1:1 allocation to one of 3 intervention arms for an 18-month weight management trial: face-to-face/conventional diet (FTF/CD), remote delivery/conventional diet (RD/CD), or remote delivery/enhanced Stop Light Diet (RD/eSLD). Anthropometrics were assessed at baseline 6, 12, and 18 months by staff blinded to the intervention, and self-monitoring data was collected across the 18-month study. As an unpowered, post-hoc, secondary analysis, two-sample t-tests were used to compare the weight change across 6,12, and 18 mos. and compliance across 18 mos. between adolescents with and without DS randomized to each intervention arm.

RESULTS

Adolescents with ID (n = 110) were randomized to one of three intervention arms: FTF/CD (n = 36, DS = 17, other ID = 19), RD/CD (n = 39, DS = 21, other ID = 18) or RD/eSLD (n = 35, DS = 15, other ID = 20). Body weight at 18 months was obtained from 82%, 76% and 73% of participants with DS and 84%, 83% and 75% of participants with other ID randomized to the FTF/CD, RD/CD, and RD/eSLD arms, respectively Weight change across 18 months was -0.2 ± 8.8 kg (-0.5%), -0.3 ± 5.3 kg (-0.7%), and -2.6 ± 5.0 kg (-4.0%) in adolescents with DS randomized to the FTF/CD, RD/CD and RD/eSLD arms, respectively. There were no significant differences in change in body weight or BMI across 18 months between adolescents with DS or those with other ID in any of the 3 intervention arms (all p > 0.05). Additionally, there were no significant differences in intervention compliance between adolescents with and without DS across 18 mos. (all p > 0.05).

CONCLUSIONS

Adolescents with DS respond to a multi-component weight management intervention similar to those with others ID.

Calcium, fiber, iron, and sodium intake in adolescents with intellectual and developmental disabilities and overweight and obesity

BACKGROUND

Adolescents with intellectual and developmental disabilities (IDD) and overweight or obesity (OW/OB) are a nutritionally vulnerable group with increased risk of nutritional deficiencies. However, there are limited data examining micronutrient intake in adolescents with IDD and OW/OB.

OBJECTIVE

The purpose of this study was to assess the adequacy of calcium, iron, fiber, and sodium intake referenced against the United States Dietary Reference Intakes in adolescents with IDD and OW/OB.

METHODS

Three-day image-assisted food records were used to assess dietary intake of 64 adolescents with IDD and OW/OB. A mean ± standard deviation was calculated for mean intake of calcium (mg), fiber (g/1000 kcals energy), iron (mg), and sodium (mg).

RESULTS

A total of 157 nutrient intake observations were completed by 64 participants (56% female, 16.3 ± 2.3 years). Calcium intake for participants ages 14-18 years (n = 57) was 1027.4 ± 607.5 mg, which is below the EAR of 1050 mg. Calcium intake for participants ages ≥19 years (n = 7) was 921.1 ± 596.4 mg, which is greater than the EAR of 840 mg. Fiber intake was 8.4 ± 3.6 g/1000 kcals, which is below the AI of 14 g/1000 kcals. Iron intake for all participants exceeded their respective EARs. Sodium intake was 3180.9 ± 975.9 mg, which above the AI of 2300 mg.

CONCLUSION

Calcium intake was adequate for participants ≥19 years of age, but inadequate for participants 14-18 years. For all participants, iron and sodium intake exceeded the DRI while fiber intake was below the DRI.

POWERSforID: Personalized online weight and exercise response system for individuals with intellectual disability: A randomized controlled trial

BACKGROUND

Obesity is associated with early mortality and chronic disease among adults with intellectual disability (ID), yet there is a paucity of effective weight management interventions for this population.

OBJECTIVE/HYPOTHESIS

This pilot study examined a tailored intervention on weight loss, waist circumference, A1c, and lipid profile among adults with ID.

METHODS

Obese adults (BMI ≥ 30 kg/m2) with mild to moderate ID were randomized to an intervention (n = 17) or comparison group (n = 18) for a 24-week trial. All participants completed health-related questionnaires and clinic visits. Participants in the intervention group received access to an online weight management platform that assisted them in monitoring their diet and physical activity along with weekly coaching calls (weeks 1-12) that were tapered off to calls every other week (weeks 12-24). The comparison group completed questionnaires and clinic visits, but did not receive access to the online platform or calls. Differences in weight, waist circumference, percent body fat, A1c, lipid profile were assessed at baseline and at week 24.

RESULTS

The intervention group reduced body weight by an average of 2.7% (-2.6 kg; p = 0.02) and waist circumference by 3.4% (-3.89 cm; p = 0.02) versus the comparison. There were no statistically significant group by time interactions observed among other variables.

CONCLUSION

Adults with ID who received the intervention were able to maintain or slightly reduce their body weight and waist circumference after the 24-week intervention. Despite not achieving the targeted sample size, the pilot study findings serve as a basis for developing accessible weight management interventions for people with ID.

Weight Loss Interventions for Adolescents With Intellectual Disabilities: An RCT

OBJECTIVES

In this randomized trial, we compared the effectiveness of 2 diets (enhanced stop light diet [eSLD] versus conventional meal plan diet [CD]) and 2 delivery strategies (face-to-face [FTF] versus remote delivery [RD]) on weight loss across 6 months in adolescents with intellectual and developmental disabilities who were overweight or obese.

METHODS

Participants were randomly assigned to 1 of 3 arms (FTF/CD, RD/CD, or RD/eSLD) and asked to attend one-on-one sessions with a health educator every 2 weeks to aid in maintaining compliance with recommendations for a reduced-energy diet and increased physical activity. The CD followed the US dietary guidelines. The eSLD used the stop light guide and was enhanced with portion-controlled meals. The FTF arm was delivered during in-person home visits. The RD arms were delivered by using video conferencing.

RESULTS

A total of 110 adolescents with intellectual and developmental disabilities (aged ∼16 years, 53% female, BMI 33) were randomly assigned to the FTF/CD (n = 36), RD/CD (n = 39), or RD/eSLD (n = 35) group. Body weight at 6 months was obtained from 97%, 100%, and 86% of participants in the FTF/CD, RD/CD, and RD/eSLD arms, respectively. The eSLD elicited significantly greater weight loss than the CD: RD/eSLD (-5.0 ± 5.9 kg; -6.4%) versus RD/CD (-1.8 ± 4.0 kg; -2.4%) (P = .01). However, weight loss did not differ by delivery strategy: FTF/CD (-0.3 ± 5.0 kg; -0.2%) versus RD/CD (-1.8 ± 4.0 kg; -2.4%) (P = .20).

CONCLUSIONS

The eSLD elicited significantly greater 6-month weight loss compared with a CD when both interventions were delivered remotely. Minimal 6-month weight loss, which did not differ significantly between FTF delivery and RD, was observed with a CD.

Health promotion in adults with Down's syndrome: Experiences of caregivers

Individuals with Down's syndrome rely on caregivers to support lifestyle behaviour change. It is therefore important to understand how caregivers put health recommendations into practice. Through conducting semi-structured interviews, the present study sought to understand the facilitators and barriers that caregivers faced when implementing health promotion advice. Five interviews were conducted with paid support staff and four with family carers of individuals attending a specialist multidisciplinary Down's syndrome health promotion screening clinic. Three main themes emerged in their accounts, including active promotion of weight management by caregivers, benefits of working practices such as record keeping and communication channels and the importance of having access to social care services and recreational activities. These findings have important implications for professionals working in specialised healthcare settings who may be able to tailor communication and services to better meet the needs of individuals with Down's syndrome and their caregivers.

Sleeve Gastrectomy for Youth With Cognitive Impairment or Developmental Disability

BACKGROUND AND OBJECTIVES

Youth with cognitive impairment or developmental disability (CI/DD) face higher rates of obesity and secondary medical issues. Bariatric surgery may be a helpful tool for health improvement because it has been shown efficacious for adolescents. We aim to contribute to literature regarding bariatric surgery for adolescents with CI/DD and explore the association between cognitive functioning and weight loss outcomes.

METHODS

Adolescents (N = 64) received a preoperative psychological evaluation, including cognitive assessment, and bariatric surgery at 1 weight loss program between 2010 and 2017. For these adolescents with measured cognitive performance, CI/DD was defined by an IQ <80 or previous diagnosis. In analyses, we compared adolescents with and without CI/DD. Structural equation modeling was used to assess the impact of cognitive functioning on weight loss 3 to 24 months postsurgery.

RESULTS

There were no significant differences between adolescents with or without CI/DD in terms of preoperative BMI, age, and sex. Having CI/DD did not significantly impact weight loss or weight loss trajectory in the 2 years after surgery, although modeling revealed a trend toward individuals with CI/DD losing more weight over time. Similarly, intelligence scores did not predict weight loss after surgery.

CONCLUSIONS

Bariatric surgery may be a helpful tool for adolescents with severe obesity and CI/DD. They could benefit from the surgery as much as those with typical development, and having CI/DD should not be used as a criterion to deny surgery. Continuing research with this population can be used to determine long-term outcomes in addition to defining best practices.

Adjusting a mainstream weight management intervention for people with intellectual disabilities: a user centred approach

Background

People with intellectual disabilities (ID) may not be able to access and respond to uniformly delivered health interventions. Public bodies have a legal duty to make ‘reasonable adjustments’ to policies and practices to provide fair access and treatment for people with ID. This study aimed to identify adjustments to the Slimming World weight management programme to improve accessibility and assess acceptability and feasibility for this population.

Methods

This user-centred qualitative study was carried out with a steering group of people with ID (n = 4). Barriers and facilitators to using Slimming World were identified through interviews and focus groups with people with ID (n = 54), carers (n = 12) current members with ID (n = 8) and Slimming World group leaders (n = 11). Adjustments were made and their feasibility and acceptability were explored in a before-and-after mixed methods study where people with ID attended Slimming World for eight weeks. Participants (n = 9), carers (n = 7) and Slimming World group leaders (n = 4) were interviewed to explore their experiences of the adjustments. Participants were weighed at baseline then each week.

Results

Four key adjustments were identified and addressed by Slimming World who developed prototype Easy Read materials and a letter for carers. Six of the nine participants attended Slimming World for eight weeks and lost weight (1.4 kg to 6.6 kg, reduction in BMI between 0.5 and 1.7 kg/m2), indicating that the adjustments were feasible and acceptable. Two participants dropped out because they felt uncomfortable in a mainstream group and another left because they lacked control over food choice in their residential setting.

Conclusions

This user-centred approach identified reasonable adjustments that were feasible to implement. In a small uncontrolled feasibility study, people with ID were positive about the adjustments and lost weight. However, issues in the wider context of people’s lives, such as obesogenic environments and concerns about joining mainstream groups, limited the acceptability of Slimming World even with these adjustments. These findings have important implications for policy and suggest that environmental and organisational level interventions are needed alongside those targeting individual behaviour to tackle the obesogenic environment in which many people with ID spend their time, in order to reduce inequalities associated with the consequences of obesity.
