Secondary study designRandomised controlled trial
Study setting(s)Not specified
Study typeQuality of life
Scientific title
Study objectivesIt is hypothesised that long-term electronic communication through the web and e-mails (the Health Portal) provides an efficient means of increasing exposure to advice on healthy behaviour and to facilitate adherence and sustainability.
Ethics approval(s)Approval received from the Medical Ethical Committee of the Erasmus Medical Center on 23rd July 2007 (ref: MEC-2007-113).
Health condition(s) or problem(s) studiedNutrition, health promotion, physical activity, worksite
Intervention1. Usual care control group:
Standard worksite health promotion program consisting of a questionnaire, a health check with a biometric assessment and access to a restricted part of the Health Portal on the Internet containing personal results on the questionnaire and health check and general information on health.

2. Intervention group:
On top of the standard worksite health promotion program the intervention group will have access to the personalised Health Portal on the Internet, which is built on four critical features:
2.1. Computer-tailored advice on physical activity and nutrition
2.2. Reports on individual progress in self-reported weight, body mass index, physical activity and fruit and vegetable consumption
2.3. Opportunity to contact professionals through e-mail
2.4. Continuous support and feedback through e-mail by a personal coach
After 12 months the monthly contact by a personal coach will be terminated, but access to the Health Portal will remain for another 12 months.

Data will be collected by means of a questionnaire at baseline, and after 12 and 24 months and a health check at baseline and after 24 months.
Intervention typeOther
Primary outcome measure1. Change in (moderate and vigorous) physical activity level using the International Physical Activity Questionnaire, measured at baseline and after 12 and 24 months
2. Change in level of fruit and vegetable intake using the short Dutch Food Frequency Questionnaire, measured at baseline and after 12 and 24 months
Secondary outcome measures1. Self-efficacy and perceived barriers on physical activity and fruit and vegetable consumption, measured at baseline and after 12 and 24 months
2. Change in self-reported saturated fat intake, measured at baseline and after 12 and 24 months
3. By using the SCORE system a risk profile on cardiovascular disease, consisting of systolic blood pressure, gender, smoking and total cholesterol level will be assessed, measured only at baseline and after 24 months
4. Body mass index, waist circumference and body fat percentage, measured only at baseline and after 24 months
5. Endurance, measured only at baseline and after 24 months
