Sophia Step Study - a Behaviour Change Program on Physical Activity in Persons With Pre- and Type 2 Diabetes
Study Details
Study Description
Brief Summary
The aim of the study is to investigate the effects of two levels of primary care physical activity interventions on metabolic control and cardiovascular risk factors, compared to usual care in patients with pre- and type 2 diabetes.
The hypothesis is that both levels of interventions have effect on HbA1c with the more intense Group intervention having superior effects.

Detailed Description
Regularly physical activity may decrease the risk for type 2 diabetes, cardiovascular diseases, overweight and premature deaths. Despite the evidence that physical activity is beneficial to health,it is often ignored and underused aspect in diabetes care. The aim of the study is to investigate the effects of two levels of primary care physical activity interventions on metabolic control and cardiovascular risk factors, compared to usual care in patients with pre- and type 2 diabetes.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Group A Participants in the intensive intervention group (A) receive a pedometer intervention and 12 group meetings over two years' time, with the majority of meetings being held in the first 6 months. The group meetings constitutes of a 30 min walk and 60 min group consulting based on techniques for behaviour change using an interactive program with positive feed-back following their steps on a website. One occasion is taking place at a gym with instruction for a home-based strength training program. Participants receive 10 individual consultations with a diabetes specialist nurse. |
Behavioral: Pedometer intervention
Intensive intervention with pedometer. The participants are instructed to set daily step goal and to record their daily steps on a website.
Behavioral: Group meetings
Participants receive 12 group meetings over two years' time.
Behavioral: Individual consultations
Participants receive 10 individual meetings with a diabetes specialist nurse. Physical activity on prescription is used to set individual goals and to highlight the importance of physical activity.
|
| Experimental: Group B Participants in the pedometer group (B) receive a pedometer intervention. Henceforth they are left to continue by they own for two years. |
Behavioral: Pedometer intervention
Intensive intervention with pedometer. The participants are instructed to set daily step goal and to record their daily steps on a website.
|
| No Intervention: Group C The control group (C) receive diabetes care as usual except for the extra measurements included in the study. Diabetes care as usual is meeting a diabetes specialist nurse and a general practitioner once a year receiving lifestyle advice and physical activity on prescription. |
