Scientific titleA randomised controlled trial of the benefits of exercise early in the management of Type 2 diabetes
Study acronymThe Early ACTID Study
Study objectivesAn ideal treatment for diabetes would improve glycaemic control by decreasing insulin resistance and improving insulin secretion without the side effect of weight gain. To date no pharmacological agents have been able to satisfy all of these criteria. In contrast, increased physical activity has the potential to offer all of these benefits with little or no side-effects. Hence it should represent the ideal first line treatment for Type 2 diabetes and for maximal benefit should be instituted early. Whilst we know that lifestyle intervention can be an effective treatment for those individuals with impaired glucose tolerance, i.e. in a pre-diabetic state, what we seek to establish is whether increased physical activity (using a simple home-based exercise programme) and dietary changes can alter the course of established type 2 diabetes.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedType 2 diabetes
Intervention1. Intensive dietary intervention
2. Increased exercise and intensive dietary intervention
3. Control: Usual Care

Individuals recruited into all 3 arms of the trial will have their diabetes and blood pressure management taken over by Early ACTID for the duration of the trial. Both intervention arms are based on regular counselling sessions with a research nurse and/or dietitian to encourage changes to the patients lifestyle.
Intervention typeOther
Primary outcome measure(s)

Glycaemic control as measured by HbA1c and systolic and diastolic blood pressure, at 6 months.

Key secondary outcome measure(s)

Lipids, insulin resistance, weight/body composition, and amount of medication required to control diabetes and blood pressure at 12 months.
