The baseline survey of the North Karelia Project was carried out to measure the level of cardiovascular risk factors in the target population. These data on the prevalence, detection and treatment of hypertension obtained in the survey were utilized in planning the main programme. The survey was carried out in 1972 and 4275 persons aged from 25 to 59 (6.5% random sample) were examined. The prevalence of hypertension was high--21% of women and 15% of men were judged as being in need of treatment for hypertension. The blood pressure level of men was higher than that of women below 45 years of age, but in all age groups women were more often undergoing treatment. Although majority of people had had their blood pressure checked recently, only half of those who were aware of hypertension had ever been under treatment, and at the time of examination only 13% of those men and 10% of those women had restored normotension. Only one-fifth and one-third of the women who had used drugs had been under treatment for more than 5 years. Thus, the need to provide a systematic hypertension control scheme in North Karelia was urgent, as described in many other communities in the developed world. The main reason for this lies in the inability of the health care system which has not been able to maintain patients on long-term follow-up and treatment.
北卡累利阿项目的基线调查旨在测量目标人群中心血管危险因素的水平。该调查所获得的关于高血压患病率、检出率及治疗情况的数据被用于规划主要项目。调查于1972年开展，对4275名年龄在25至59岁之间的人（随机抽取6.5%的样本）进行了检查。高血压患病率很高——21%的女性和15%的男性被判定需要接受高血压治疗。45岁以下男性的血压水平高于女性，但在所有年龄组中，女性接受治疗的比例更高。尽管大多数人最近都进行过血压检查，但只有一半知晓自己患有高血压的人曾经接受过治疗，在检查时，只有13%的男性和10%的女性血压恢复正常。使用过药物的女性中，分别只有五分之一和三分之一的人接受治疗超过5年。因此，正如发达国家的许多其他社区一样，在北卡累利阿迫切需要提供一个系统的高血压控制方案。主要原因在于医疗保健系统无法对患者进行长期随访和治疗。
