Recommendations for research

The Programme Development Group (PDG) recommends that the following research questions should be addressed. It notes that 'effectiveness' in this context relates not only to the size of the effect, but also to cost effectiveness and duration of effect. It also takes into account any harmful/negative side effects.

1 Total or high-risk population approach

How effective and cost effective are interventions which use either a 'total population' or 'high-risk population' approach to preventing type 2 diabetes among people from black and minority ethnic or lower socioeconomic groups?

2 Community-level interventions

What are the most effective and cost-effective ways of developing, implementing and assessing tailored and culturally appropriate community-level interventions to prevent type 2 diabetes among people at high risk? This includes people from a range of black and minority ethnic groups and those from lower socioeconomic communities.

3 Participatory approaches

Which participatory approaches are most effective and cost effective among populations at higher risk of type 2 diabetes? This should consider the awareness, knowledge, understanding and skills of the providers of interventions for people at high risk of developing type 2 diabetes?

4 Diet and physical activity behaviours

How do socioeconomic, environmental, biological and psychosocial factors determine diet and physical activity behaviours and how do they contribute to differences in the risk of developing type 2 diabetes?

5 Financial factors

How do financial factors (including incentives, pricing and taxation of food and incentives, and pricing for physical activity opportunities) affect food and physical activity choices?

More detail on the gaps in the evidence identified during development of this guidance is provided in appendix D.
