Health prophylaxis is the most effective way to reduce the incidence of diseases, and the knowledge of factors predisposing to the increase in the incidence of a given disease directs actions aimed at maintaining health. The proprietary stroke prevention program was used, which consisted in introducing dietary changes, health education and increasing the physical activity of the respondents. At quarterly intervals, each examined person was measured: blood pressure, glucose level, total cholesterol and its fractions, triglycerides, sodium and potassium levels, prothrombin time (PT), INR, PT activity, INR. The study included 40 randomly selected women (the research and control group consisted of 20 people) aged 40–60 years from the Michałowo Commune in the Białystok poviat. Additionally, an interview was collected with the completion of the proprietary questionnaire. The most important conclusions are: people aged 40–60 are the group most at risk of stroke; stroke prevention significantly reduces the likelihood of developing a stroke; normalization of test results (in the experimental group there was a decrease in body weight, normalization of blood pressure, increase in HDL level) improves the biopsychosocial state. The analysis performed is a sample and it is recommended to repeat the study on a large population.

The risk of stroke is directly proportional to the occurrence of hypertension and the simultaneous occurrence of other risk factors. The main goal was to find out which age group was most at risk of having a stroke. The study was performed among 138 people randomly chosen from Michałowo borough in the Białystok county.The examined were divided into the following 5 age group. The following measurements were performed: arterial blood pressure, blood glucose level, total cholesterol and its fractions level, triglycerides level, sodium and potassium level, prothrombine time, activity. Additionally, a patient’s history was taken and an author’s survey questionnaire was completed. Due to the small number of men surveyed (13 persons), statistically significant analysis of data within this group cannot be carried out. An analysis was made, broken down by age, of data obtained after examining 125 women. People in age group III are most at risk of developing stroke. People in the IV and V age groups are those who are at risk of having a stroke or who have had a stroke. People in groups 1 and 2 are at moderate risk of stroke. In the III age group people are the most at risk of having a stroke.
