As in other EU countries, there are large disparities in self-rated health by socioeconomic status: 80% of people in the highest income quintile population report being in good health compared with 48% of the population in the lowest income quintile (Figure 4). These include the living and working conditions of people, the physical environment in which people live, and a range of behavioural risk factors. In fact, more than 35% of the overall burden of disease in the Czech Republic in 2015 (measured in terms of OALYs) could be attributed to behavioural risk factors, including dietary risks (contributing 18%), smoking (13%), alcohol use (4%) and physical inactivity (3%) (IHME, 2016).
