[Prevention of cardiovascular diseases is effective. Initial program evaluation of the canton Tessin (1984-1989)].

This study measures and evaluates the effects of the CVD prevention programme which has been underway in the Canton of Tessin (Switzerland) since 1984. The programme was designed with the following objectives: --high blood pressure: each Tessin inhabitant should be aware of the admissible blood pressure limits, the consequences of surpassing the norm, as well as know his or her own blood pressure count and have it measured at least once a year; --tobacco consumption: a positive image of non-smokers is promoted, as well as the respect of non-smoker's rights. The population, particularly the young, are "invited" not to smoke; eating habits: each Tessin inhabitant will be provided with the information necessary to enable him/her to make rational choices concerning content in order to ensure a balanced diet, rich in fibres and low in saturated fats; activity: physical activity, at least 20 minutes three times a week, is promoted for all age groups; early warning symptoms:information will be provided to enable inhabitants to recognize indications of cardiac distress in order to diminish the time between the first pain and hospitalisation; A vast and varied information campaign was set up to pursue these objectives. Much of the campaign was implemented through use of various media (television, radio, daily and weekly press), and seconded with the periodic distribution of information tracts to all the households of the district. The mass media campaign was complemented with a variety of activities for all ages: from poster competitions, to the edition and sale of recipe books, to specific activities with professional and voluntary associations are a few examples.(ABSTRACT TRUNCATED AT 250 WORDS)
