Chronic non-communicable diseases are characterized by a long course and complications that directly affect the quality of life of patients. Prevention activities play an important role in the control of these diseases because the development of chronic non-communicable diseases can be prevented by healthy living habits that include a varied diet, physical activity, avoiding alcohol and carbonated beverages consumption and avoiding the use of addictive substances. The most common chronic non-communicable diseases associated with lifestyle are cardiovascular diseases and diabetes, the occurrence of which is significantly associated with obesity and stress exposure. To affectively plan the interventions, it is necessary to know the risk factors and to raise the public awareness about them. In addition to general prevention, it is possible to carry out more selective interventions, targeted at certain groups at increased risk, such as children and adolescents. Preventive action at the earliest age is important in order to prevent the consequences that may occur in later life, which may equally affect young people and adults both from urban and rural areas, due to the modern way of life. The purpose of this paper is to analyse the behaviour of young people in relation to their consumption of alcohol and carbonated beverages, the use of cigarettes and eating habits. In relation to the characteristics of the respondents, the mentioned habits were analysed in relation to the place of residence, gender and age. The results of this study, conducted on a sample of 104 respondents aged 14 to 19 years, show that every other person eats fruits and vegetables several times a week or every day, while fast food and fish are eaten rarely. A quarter of respondents smoke every day. One third of the respondents practice daily physical activity, and the same number of them experience stress most of the time. Most respondents recognize risk factors and diseases associated with an unbalanced diet and addictive substances consumption.
