The World Health Organization estimates that in 2020 will die of ischemic heart disease (CHD) 11.1 million people in the world, while in 2002 it was 7.22 million, of which in Europe nearly two million. High incidence particularly in developed countries emphasizes mainly on risk factors (RF) of lifestyle. Similar, not good, is the situation in Slovakia. Since the wrong habits, leading to the development of cardiovascular disease (CVD), are created in childhood and young age, we focused on the exploration of risk factors related to the lifestyle of young people in secondary schools in Slovakia (in capital city and regional city with a high proportion of students from rural areas). The survey results clearly confirm the high incidence of many RF in teenage age already, which in future may increase the risk of CVD and other civilization diseases.
