Over the last 20 years, alcohol consumption has increased by two litres per capita per year (compared to an average reduction of four litres across the OECD) and over the last decade, rates of obesity have increased by 50%, one of the steepest increases in the OECD. Of particular concern are high rates of unhealthy lifestyles in Czech children. Children who establish smoking habits in early adolescence increase their risk of cardiovascular diseases, respiratory illnesses and cancer. They are also more likely to experiment with alcohol and other drugs.
