This study was conducted to evaluate the effectiveness of health education in the Tatarstan Republic by establishing educational programs - Health Schools - for groups of patients with a high risk of developing potentially fatal cardiac and respiratory conditions. The concept of "Life Course Health Development" implies the development of mechanisms for personalized health management. The goal of the study is to explore the effectiveness of the specialized Health Schools in Tatarstan. For the comparative study of health education effects on the overall state of personal health, 590 patients were surveyed in a randomized controlled trial. The groups of patients were compared in relation to their health education; their health status was observed prior to and afterward undergoing the educative preventative programs and estimated in comparison between the two groups. Extrapolation of the data on Tatarstan's patient population was obtained through this study, taking into account the state of health of the Health Schools students, obtaining the regression equations of population mortality and the effects of training on it. The effectiveness of Health Schools for patients with cardiovascular pathology has been proven. However, additional efforts are required to involve a wider range of patients and increase learning effectiveness to critical levels of awareness by introducing new forms of education in Health Schools since it statistically significantly increased the awareness level regarding disease nature and preventive measures. ©2021 JOURNAL of MEDICINE and LIFE.
