We have extensive links across primary care that we will draw upon for this study. We will target specialist's diabetes outpatient clinics located in the community (for example Hinckley, Melton Mowbray and Oakham), the intermediate Care Division (ICD) for diabetes and secondary care.We have good links with the Leicester Royal Infirmary bariatric surgery service where a large cohort of eligible people exists on the referral list for surgery.Potentially eligible patients who have previously participated in other research studies at the LDC and have indicated a willingness to take part in additional studies will also receive a postal invite. We hold a volunteer database with the contact information and basic data of people who have expressed an interest in participating in more research further, we have a list of young adults with T2DM who have recently participated in two research studies, co-ordinated by the LDC, who have consented to being contacted for future research studies that they may be eligible for. Our PPI committee has also recommended approaching at-risk groups, such as slimming clubs/weight watchers. Therefore we will contact such groups within the local community and the research team will run recruitment fares in those groups who agree.
