RESULTS AND PROBLEMS OF A REGIONAL FOLLOW -UP-STUDY IN THE PREVENTIONOF CARDIOVASCULAR-DISEASE

A one-year prospective cohort study of different employee populations- altogether 122 men and 197 women-resulted in a statistically significa nt improvement of the cardiovascular risk factor profile of white-coll ar workers but not of blue-collar workers. There were also differences in sexes. The men in the study had reduced systolic and diastolic blo od pressure rates and lowered serum cholesterol levels (p < 0.05). The women had reduced diastolic blood pressure and lowered serum choleste rol levels (p < 0.05). Results and problems in interpreting the study are discussed.
