    Abstract:
    INTRODUCTION: We investigated the impact of general health screenings and discussions with general practitioners on the cardiovascular risk profile of the population. MATERIAL AND METHODS: A population-based, randomised, controlled, 5-year follow-up trial conducted in a primary care setting. In total 2000 randomly selected men and women, aged 30-50 years, from family practices in the district of Ebeltoft, Denmark. Of these persons, 1507 (75.4%) agreed to participate, and were randomised into: (1) a control group who did not receive health screenings; (2) an intervention group that received two health screenings; or (3) an intervention group that received both the two screenings and a 45-minute follow-up consultation annually with their general practitioner. All were followed up after 5 years by questionnaires and health screenings. The outcome measures were: cardiovascular risk score (CRS), body mass index (BMI), blood pressure, serum cholesterol, carbon monoxide in expiratory air, and use of tobacco. RESULTS: After 5 years, the CRS, BMI, and serum cholesterol levels were lower in the intervention groups, as compared with the control group. The improved outcome was greater in the baseline risk groups. The number of persons with elevated CRS in the intervention groups was about half the number of persons with elevated CRS in the control group. The difference was not a result of medication use. There was no difference between the group that received consultations after the screenings and the group that had health screenings alone. DISCUSSION: Systematic health screenings reduce the cardiovascular risk score in a middle-aged population. After 5 years of follow-up, the number of persons at elevated cardiovascular risk was about half the expected. The impact of intervention is higher in at-risk individuals. Planned consultations about health did not appear to improve the cardiovascular profile of the study population.
