The prevalence of five lifestyle risk factors in primary care physicians: A cross-sectional study in Switzerland.

Having a healthy lifestyle is important not only for the health of physicians, but also for the realisation and effectiveness of counselling on patients. Information on lifestyle habits and the presence of health-related behaviours in primary care physicians (PCPs) is lacking. Using a cross-sectional study design, an anonymous questionnaire was sent to a random sample of 1'000 PCPs practicing in the seven Western cantons of Switzerland. In our sample, we assessed the presence of five lifestyle risk factors, namely current smoking, at risk alcohol consumption, insufficient physical activity, being overweight and insufficient hours of sleep. 510 physicians participated in our study (51% participation rate). Respondents were 51% women, with a majority of general practitioners (67%), followed by paediatricians (19%) and gynaecologists (14%). 57% of PCPs had no or one lifestyle risk factor, 40% had two or three and 3% had four or all five. The average number of lifestyle risk factors was 1.39. Insufficient physical activity was the most prevalent lifestyle risk factor (40%), followed by excess weight and insufficient hours of sleep (32%), at risk drinking (25%) and current smoking (9%). Having ≥2 lifestyle risk factors was associated to being a man, working in a solo practice and for ≥7 half-days per week. Overall, a majority of Swiss PCPs have no or one lifestyle risk factor, but certain unfavourable health-related behaviours are present, notably insufficient physical activity. Developing strategies and courses to improve physicians' lifestyles should be proposed early on in the medical curriculum.
