A manualised weight management programme for adults with mild–moderate intellectual disabilities affected by excess weight: A randomised controlled feasibility trial (Shape Up-LD)

Background

The aim was to pilot an adapted manualised weight management programme for persons with mild–moderate intellectual disabilities affected by overweight or obesity (‘Shape Up-LD’).

Method

Adults with intellectual disabilities were enrolled in a 6-month trial (3-month active intervention and 3-month follow-up) and were individually randomised to Shape Up-LD or a usual care control. Feasibility outcomes included recruitment, retention, initial effectiveness and cost.

Results

Fifty people were enrolled. Follow-up rates were 78% at 3 months and 74% at 6 months. At 3 and 6 months, controlling for baseline weight, no difference was observed between groups (3 months: β: −0.34, 95% confidence interval [CI]: −2.38, 1.69, 6 months: β: −0.55, 95%CI −4.34, 3.24).

Conclusion

It may be possible to carry out a trial of Shape Up-LD, although barriers to recruitment, carer engagement and questionnaire completion need to be addressed, alongside refinements to the intervention.
