  Background
People with intellectual and developmental disabilities (IDD) are at risk of developing long term health conditions, and a preventative health agenda research is emerging. However, little is known about the recruitment settings, delivery contexts, intervention techniques and outcomes of health promotion programmes for this population. Therefore, the aim of this review was to synthesize and evaluate these characteristics.

Method
A systematic review of studies identified from multiple databases on healthy lifestyle interventions for adolescents and young people with IDD was conducted. Data were synthesized and evaluated using a logic model. Quality of rigour was also assessed.

Results
Sixteen geographically diverse studies were selected and evaluated. Participants were most commonly recruited from schools, with interventions typically taking place in a gym setting and involving physical activity training.

Conclusions
This review indicates that physical activity and dietary interventions in people with IDD may lead to lifestyle changes, however more robust evidence is required. Educational settings are conducive, with settings beyond schools requiring further consideration.
