Chronic diseases share similar risk factors associated with four daily behaviours: unbalanced diet, sedentary lifestyle (physical inactivity and time spent sitting down), smoking and alcohol consumption. These diseases are responsible for 74% of deaths worldwide. Despite the frequency with which practitioners witness these bad habits in their patients, little time is devoted to lifestyle advice during medical visits, and even less to using effective techniques to discuss their behaviour. Yet medical and paramedical consultations could be an essential educational opportunity to promote a healthy lifestyle. But advice is often limited during medical check-ups, due to a lack of time and suitable tools, and is often focused on a particular risk factor. To date, there is no procedure for screening and behavioural intervention to deal with harmful lifestyle habits in patients.
