Background: Physicians' own Physical Activity (PA) and other health-related habits influence PA promotion. The present study identifies the PA level, according to the current PA recommendations and other health-related habits of physicians from the Catalan Medical Council. Methods: 2,400 physicians (30 to 55 years) were randomly selected to generate a target sample of 800; each received a self-administered questionnaire identifying medical specialization, work setting, health self-perception, body mass index (BMI), PA and smoking habits. Results: 762 physicians responded (52% female). Almost one in two (49.3%) exercised sufficiently, nearly all selfperceived good health, while 80.5% were non-smokers. Almost 6 in 10 males reported overweight or obesity (56.9%) versus 18.2% of females. Active physicians dominated specific groups; (i) aged 45-55 years, (ii) specializing either in primary care or surgery, (iii) working in the private sector, (iv) BMI <25 kg/m 2 , (v) perceiving themselves in good health, or (vi) having free leisure time. Conclusions: Only half of Catalan physicians met current PA recommendations; male physicians were particularly at risk of overweight/obesity. Overweight and under exercise were associated with private workplaces and positive health perceptions, meaning that it is it is now possible to target inactive and/or overweight Catalan physicians in future interventions.
