Plain English Summary

Background and study aims
The risk of HIV patients developing diabetes has been reported to be up to four times higher compared to those without HIV. Lifestyle modifications can prevent type 2 diabetes in the general population; given the differences in the cause of diabetes in HIV, and potential HIV-specific barriers to lifestyle change, it is important to develop effective methods in this population. Therefore, this study aims to find out an effective lifestyle intervention for treating diabetes in HIV.

Who can participate?
The study is open to people living with HIV registered as patients at Guy's and St Thomas' Hospital in London, UK

What does the study involve?
Part 1: In this comparison study, 162 participants grouped according to blood glucose levels have factors associated with type 2 diabetes studied.
Part 2: In this initial study up to 46 patients with insulin resistance receive 6 months of advice to change diet and physical activity. Change in insulin resistance is measured.
Part 3: Participants are interviewed to assess the acceptability of the intervention, and describe what helps and what hinders lifestyle change.
Part 4: Two focus groups of 6-10 participants discuss findings to aid the design of a future large-scale study.

What are the possible benefits and risks of participating?
Participants with pre-diabetes are eligible to take part in a 6-month intervention aiming to reduce their risk of developing diabetes; however, this is an initial study and the degree of potential success is not yet known. Participants in the study will help define risk factors for developing type 2 diabetes.

Where is the study run from?
Guy's and St Thomas' Hospital (UK)

When is the study starting and how long is it expected to run for?
December 2013 to August 2015

Who is funding the study?
National Institute for Health Research (NIHR) (UK)

Scientific title

Prevention of type 2 diabetes in HIV: a pilot study of effectiveness and acceptability: a non-randomised controlled trial

Study hypothesis

1. Can individualised lifestyle advice reduce insulin resistance in HIV patients with pre-diabetes?
2. Is this advice acceptable to participants?
3. Are barriers to lifestyle change HIV-specific?
