Legend: From 1982 to 2014, the age-standardized prevalence of current smoking decreased from 39.6% (95% CI 35.0–44.2) to 14.2% (95% CI 11.4–17.0) among male physicians and from 12.4% (95% CI 10.7–14.2) to 5.1% (95% CI 4.3–6.0) among female physicians (Fig. 1). Age-standardized prevalence of past smoking increased from 23.4% (95% CI 19.3–27.4) to 25.2% (95% CI 22.0–28.4) among male physicians and from 10.3% (95% CI 8.1–12.6) to 16.3% (95% CI 14.6–18.0) among female physicians over the study period. Age-standardized prevalence of never smoking increased from 34.2% (95% CI 29.9–38.5) to 50.8% (95% CI 47.1–54.5) among male physicians and from 74.4% (95% CI 71.7–77.2) in 1982 and 78.5% (95% CI 76.7–80.4) in 2014
