The prevalence of obesity rates has been reported to be higher in adults with Intellectual Disabilities (ID) than in the general population⁽Reference Melville, Cooper and Morrison¹⁾. It is likely that multi-component weight management interventions that involve carers could have considerable impact on process and potentially on actual weight loss for adults with ID⁽Reference Hamilton, Hankey and Miller²⁾. To date no studies have explored the role of carers in supporting adults with ID and obesity during a weight loss programme. The aims of the present study were (i) to explore perceptions of carers supporting adults with ID as they participated in a 6-month multi-component weight loss intervention (TAKE 5), (ii) to identify strategies that carers and participants adopt to overcome barriers to changes in lifestyle, and (iii) to record carers' perceptions of the acceptability and utility of the multi-component weight loss intervention.

TAKE 5 is a multi-component weight loss intervention that is consistent with recommendations included in current clinical guidelines⁽Reference Melville, Boyle and Miller³⁾. TAKE 5 comprised nine individual sessions delivered to fifty-four adults (≥18 years) with ID and obesity (BMI≥30 kg/m²), involving carers (paid carers or family carers) to support the participants where appropriate. The TAKE 5 intervention aimed for a 5% weight loss from initial body weight after 6 months. A purposive sampling method was used to incorporate the experiences of twenty-four carers who were paid (n 16) or family carers (n 8) and who supported participants who successfully achieved a 5% weight loss (n 12) or did not (n 12). One to one semi-structured interviews were conducted and later transcribed verbatim at week 24. The transcripts were analysed using ATLAS ti 5.2 software, alongside a ‘thematic analysis’⁽Reference Braun and Clarke⁴⁾ as a qualitative analytical method.

The main themes that emerged on analysis were carers' perceptions on participants' health; barriers and facilitators in weight loss and carers' perceptions of the multi-component weight loss intervention. Carers described the weight loss as being beneficial to participants' health. Furthermore, they discussed their efforts to encourage and aid participants to improve their diet and physical activity. However, lack of sufficient support and poor communication among carer colleagues were identified as being inhibitory. The need for resources tailored to aid weight loss among adults with ID was also highlighted.

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