Conditions
Interventions
The study is an open, randomized controlled intervention trial. Participants will be randomized to DirectLife intervention or control group. The control group will be offered use of DirectLife after t
Vries and Mudde, 1998), DirectLife takes into account the current individual activity level, and subsequently provides a personal goal. Very briefly, DirectLife consists of three elements, namely:
1.
2. A personal website
3. A personal e-coach, who provides regular updates by e-mail of the physical activity status and gives advice to increase physical activities.
By means of these elements, DirectLife increases awaren

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Level of daily activity, as measured using independent tri-axial accelerometers. These accelerometers have been validated against energy expenditure measured using VO2-max. We will use this independent measure of activity, because: A. The DirectLife activity monitor is part of the intervention therefore not independent not suitable as measure of end point; B. The Genea accelerometer yields more detailed data on physical activity. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Other metabolic and anthropometric parameters: weight, waist hip ratio, body fat percentage (BIA) and blood pressure will be measured at baseline and at the final visit, and blood sampling for total cholesterol, HDL-cholesterol, triglycerides, fasting glucose, fasting insulin and HbA1c; 2. Well being and perceived health will be assessed by RAND-36 questionnaire prior to the trial and after the trial; 3. Sleep quality will be assessed by the Pittsburg Sleep Quality Index (PSQI). | — |
