Community control of hypertension- experiences from Finland.

The improvement in the hypertension control in Finland started in the 1970s by the activities of the North Karelia Project, a comprehensive programme for the control of cardiovascular diseases. The blood pressure level of the population has had a continuous downward trend according to the population surveys conducted every fifth year since 1972 and the rule of halves has changed to the rule of two-thirds. The serum cholesterol level has decreased among hypertensives, even though it is still higher than among normotensives; the patients with antihypertensive drug treatment smoke less than the rest of the population. However, the situation is far from optimal; BP levels are high and body mass index is continuously increasing among the patients. The need for intensifying both pharmacological and nonpharmacological treatment among the hypertensives on a large scale is obvious.
