[Updated Swedish National Guidelines on prevention and lifestyle habits: physicians' role].

The recently updated Swedish National Guidelines on prevention and lifestyle habits (tobacco use, hazardous use of alcohol, insufficient physical activity and unhealthy eating habits) emphasize the importance of supporting lifestyle changes among risk individuals, such as already affected by disease, carriers of risk factors that increase the risk of disease, and people with social vulnerability. More measures targeting youth are included, as well as measures to avoid smoking and alcohol use prior to surgery. Physicians have a key role in implementation of the new guidelines, as a great majority of patients who attend healthcare and discuss lifestyle habits do so with a physician.
