| Scientific title | A randomised controlled trial on the preventive effects of a physical activity enhancing and healthy eating program on weight control among an overweight working population |
| Study acronym | ALIFE@Work |
| Study hypothesis | It is hypothesised that participation in a healthy lifestyle program, aimed at controlling body weight by increasing physical activity and improving eating habits, may contribute to the reduction of overweight, to weight maintenance and consequently to the prevention of health problems, like type two diabetes mellitus, hypertension, hypercholesterolaemia and cardiovascular diseases. |
| Ethics approval(s) | The study design, procedures and informed consent form were approved by the Medical Ethics Committee of the VU University Medical Center (ref: 03/193), and all participants provided written informed consent. |
| Condition | Overweight |
| Intervention | Block randomisation was used. In this randomised controlled trial, 1386 overweight employees are participating and being followed for two years. Participants are employees working at seven different companies throughout The Netherlands. At baseline, employees were randomised to either one of two intervention conditions (phone-based [N = 462] or Internet-based intervention [N = 464]) or a reference group (N = 460). In addition, employees were randomised to either a group of employees having basic measures only (80% out of each group) or to a group of employees having additional measures (i.e. waist circumference, body fat percentage, blood pressure, total cholesterol level and fitness level; 20% subjects of each group). The two-step randomisation means there are six groups an employee could be assigned to. Subjects in the phone-based group received the healthy lifestyle intervention program in a binder and were counselled by phone; subjects in the internet-based group followed the same program on the Internet and were counseled by e-mail. Subjects in the reference group received information brochures with general information on overweight, physical activity and healthy nutrition, and were not counselled. The intervention program lasted six months and took place in the first half year of the two years. |
