actions and habits of a person that have a direct impact on his physical and mental health. These factors include smoking, alcohol consumption, physical activity level, diet, sleep and rest patterns, and behaviours related to disease prevention and treatment (e.g., screening, vaccination, adherence to medical advice). These factors can be modified or adjusted to improve health and reduce the risk of chronic and infectious diseases. The importance of behavioral factors is explained by the fact that they significantly affect the quality of life and life expectancy of the population.
