Adults with intellectual disabilities experience high rates of obesity. Despite this higher risk, there is little evidence on the effectiveness of weight-loss interventions for adults with intellectual disabilities and obesity. The present study examined the effectiveness of the TAKE 5 multi-component weight-loss intervention. Adults with obesity were invited using specialist intellectual disability services to participate in the study. Obesity was defined as a BMI of 30 kg/m 2 or greater. TAKE 5 included a daily energy-deficit diet of 2510 kJ (600 kcal), achieved via a personalised dietary prescription. Participants' body weight, BMI, waist circumference and levels of physical activity and sedentary behaviour were measured before and after the intervention. A total of fifty-four individuals consented to participate, of which forty-seven (87 %) completed the intervention in the study period. There was a significant decrease in body weight (mean difference 24·47 (95 % CI 25·91, 2 3·03) kg; P,0·0001), BMI (21·82 (95 % CI 2 2·36, 2 1·29) kg/m 2 ; P,0·0001), waist circumference (26·29 (95 % CI 2 7·85, 24·73) cm; P,0·0001) and daily sedentary behaviour of participants (2 41·40 (95 % CI 2 62·45, 220·35) min; P¼ 0·00 034). Of the participants who completed the intervention, seventeen (36·2 %) lost 5 % or more of their initial body weight. Findings from the study suggest that TAKE 5 is an effective weight-loss intervention for adults with intellectual disabilities and obesity. The effectiveness of TAKE 5 should be examined further in a controlled study.

Background Carers can have a significant impact supporting people with intellectual disabilities to make healthy lifestyle choices. This study examines carers' training needs on diet and physical activity. Methods A cross-sectional survey was undertaken of the knowledge and perceptions of carers supporting adults with intellectual disabilities. An interviewer administered questionnaire was used to examine carer knowledge of public health recommendations on diet and physical activity; perceptions of the benefits of healthy diets and physical activity levels; and the carer views on the barriers to change experienced by individuals with intellectual disabilities. Results Sixty-three carers took part in the study. They generally had a low level of knowledge around public health recommendations on diet and physical activity. Greater importance was attributed to the health benefits of diet than physical activity. Carers rated intrapersonal barriers to change within the person with intellectual disabilities as more important, than interpersonal or external barriers to change, with significant differences in perceived barriers relevant to diet and physical activity. Conclusions Carers supporting adults with intellectual disabilities have significant training needs relevant to promoting healthy lifestyles. This highlights the opportunity to promote health improvement via the development, and provision, of effective training initiatives.

The supportive aspects of therapeutic relationships were particularly important to participants undergoing CBT. The clinical implications are considered.

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.

There have been few published controlled studies of multi-component weight management programmes that include an energy deficit diet (EDD), for adults with intellectual disabilities and obesity. The objective of this study was to conduct a single-blind, cluster randomised controlled trial comparing a multi-component weight management programme to a health education programme. Participants were randomised to either TAKE 5, which included an EDD or Waist Winners Too (WWToo), based on health education principles. Outcomes measured at baseline, 6 months (after a weight loss phase) and 12 months (after a 6-month weight maintenance phase), by a researcher blinded to treatment allocation, included: weight; BMI; waist circumference; physical activity; sedentary behaviour and health-related quality of life. The recruitment strategy was effective with fifty participants successfully recruited. Both programmes were acceptable to adults with intellectual disabilities, evidenced by high retention rates (90 %). Exploratory efficacy analysis revealed that at 12 months there was a trend for more participants in TAKE 5 (50·0 %) to achieve a clinically important weight loss of 5-10 %, in comparison to WWToo (20·8 %) (OR 3·76; 95 % CI 0·92, 15·30; 0·064). This study found that a multi-component weight management programme that included an EDD, is feasible and an acceptable approach to weight loss when tailored to meet the needs of adults with intellectual disabilities and obesity.
