Lifestyle and Glucose Lowering Medication in T2DM

Not Applicable

Completed

• Conditions: Diabetes Mellitus, Type 2
• Interventions: Behavioral: Standard care; Behavioral: U-TURN

• Registration Number: NCT02417012
• Lead Sponsor: Rigshospitalet, Denmark

Brief Summary

This study evaluates the effect of a lifestyle intervention maintenance of glycemic control while reducing glucose lowering drugs in patients with type 2 diabetes mellitus. The intervention group receives an intensive lifestyle intervention including exercise and diet lifestyle modifications. The reference group receives diabetes educational advice. Both groups will have their pharmacological treatment regulated across the study. The primary hypothesis is that lifestyle change is sufficient to maintain glycemic control while decreasing the anti-diabetic medication in a sample patients with type 2 diabetes mellitus.

Detailed Description

Adherence to lifestyle modifications including increased exercise and healthy diet improves glycemic control in patients with type 2 diabetes mellitus. However, few have investigated the combined effects of these lifestyle changes on maintenance of glycemic control while decreasing the usage of anti-diabetic medications.

The primary hypothesis is that lifestyle change is equivalent in maintaining glycemic control (Hba1c) compared to the standard pharmacological treatment,

The U-TURN trial also tests the effects on one key secondary outcome (glucose lowering medication) and examines the effects on sleep quality, fatigue sleepiness, sleep pattern, cardio vascular disease risk factors, psychological outcomes, blood pressure and cholesterol lowering medication. The participants (N=120) is randomized into a experimental group (N=80) and a standard care group (N=40).

Additionally, the effects of the study will be evaluated 24 month post randomization.

Arm && Interventions

Group	Intervention	Description
Standard care	Standard care	The reference group will receive diabetes education and support by trained nurses. Participants in this group will have their pharmacological treatment regulated by the study endocrinologists using a standardized pharmacological treatment. The treatment is in accordance with the Danish guidelines.
U-TURN intervention	U-TURN	The intervention group will receive an intensive lifestyle intervention including partly supervised aerobic and strength exercise, diet plans and counseling by clinical dietitians. All exercise will be supervised initially and the supervision will be reduced gradually across the 12-month intervention. Additionally, the participants will be offered educational classes on implementation of a healthy lifestyle and diabetes education and support by trained nurses. Participants in this group will have their pharmacological treatment regulated by the study endocrinologists using a standardized pharmacological treatment. The treatment is in accordance with the Danish guidelines.

Primary Outcome Measures

Name	Time	Method
Change in Hba1c	0, 3, 6, 9, 12 months	blood sampling of Hba1c

Secondary Outcome Measures

Name	Time	Method
Change in glucose lowering medication	0, 3, 6, 9, 12 months	Change in doses of Metformin, GLP-1 analog, insulin. The change will be evaluate according to changes on the pre-specified regulation algorithm.
