Introduction: Guidelines to prevent cardiovascular (CV) disease are widely available. To implement these guidelines an electronic prevention programme (EPP) with a risk calculator for general practitioners (GPs) was developed. The aim of the present study was to calculate the implementation cost per installation. Methods: This cost study is part of a larger clinical trial, studying the effects of interventions in GP-practice on the management of CV risk factors. Participating GPs were asked to install the EPP. They could take part in a group education session or receive education by e-mail, telephone or at home. After a prospective cost registration, the...

Background. The aim of the present study was to determine the predictors of surfing depth and changes in weekly physical activity and daily fat intake after 6 months.
Methods. 208 highly educated adults received access to a website (with tailored feedback) and individual coaching. Website logs and linear regression analyses were used.
Results. Positive changes were found for physical activity and fat intake. Surfing depth (visiting deeper laying pages of the website) was predicted by individual coaching and not being in line with the norm for sports (p<.001;p<.05). An increase of physical activity and a decrease of fat intake were...

Maximal oxygen uptake (VO2max) can be predicted by fixed-rate step tests. However, it remains to be analyzed as to what exercise intensities are reached during such tests to address medical safety. In this study, we compared the physiological response to a standardized fixed-rate step test with maximal cardiopulmonary exercise testing (CPET). One hundred and thirteen healthy adults executed a maximal CPET on bike, followed by a standardized fixed-rate step test 1 week later. During these tests, heart rate (HR) and VO2 were monitored continuously. From the maximal CPET, the ventilatory threshold (VT) was calculated. Next, the physiological response between maximal...

Purpose: Little is known about the adequate intervention dose of interventions to change multiple risk behaviours for cardiovascular disease. The aims of our study were to examine the effects and the dose-response effects of a tailored behaviour change programme on diet and physical activity. Methods: 314 highly educated adults were allocated at random to intervention and usual care conditions. Both conditions involved medical interventions following the guidelines. The participants receiving the intervention had access to a website with tailored feedback, group sessions and individual coaching. For the latter, they could freely determine the dose(frequency and duration) and the delivery mode(e-mail,...

Objectives: Little is known about the costs and the effects of cardiovascular prevention programs targeted at medical and behavioral risk factors. The aim was to eveluate the cost-utility of a cardiovascular prevention program in a general sample of highly educated adults after 1 year of intervention. Methods: The participants were randomly assigned to intervention (n=208) and usual care conditions (n=106). The intervention consisted of medical interventions and optional behavior-change interventions. (e.g. a tailored Web site). Cost data were registered from a healthcare perspective, and questionnaires were used to determine effectiveness (e.g. quality-adjusted life-years[QALYs]). A cost-utility analysis and sensitivity analyses using...
