In this study, behavioural programmes were grouped on the basis of programme content and delivery methods. A network meta-analysis showed that most lifestyle and diabetes self-management education and support programmes that offered at least 11 contact hours led to clinically important improvements in glycaemic control. In contrast, most diabetes self-management education programmes without added support, especially those offering 10 or fewer contact hours, provided little benefit.
Programmes with higher effect sizes tended to be those delivered in person than via technology. Lifestyle-based programmes led to the greatest reductions in BMI. Reductions in HbA1c seemed to be greater for participants with a baseline HbA1c level of 53 mmol/mol (7.0%) or greater, adults younger than 65 years, and people from minority ethnic groups.
