Excessive working hours and health complaints among hospital physicians: a study based on a national sample of hospital physicians in Germany

Objectives: To determine correlations between excessively long working hours and subjectively experienced somatic health complaints among hospital physicians. Methods: Quantitative data were collected as part of the survey “Working life, Lifestyle and Health of Hospital Physicians in Germany 2006” using self-reporting questionnaires. The individually experienced health was assessed on the basis of Zerssen’s [1] list of somatic complaints. The indicator of excessively long working hours was defined as 10 or more working hours per working day and 6 or more on-call shifts a month among full-time employees. The net sample consisted of 3295 randomly selected physicians from 515 hospitals. Results: The response rate was 58% (n=1917). Physicians with excessively long working hours (19%) had significantly higher sum score of health complaints (p=0.0001) and significantly increased mental and physical fatigue symptoms (feeling faint, languor, uneasiness, heavy legs, excessive need for sleep, trembling; p=0.0001 to 0.047), mood changes (irritability, brooding; p=0.008 to 0.014), gastrointestinal (nausea, loss of weight; p=0.0001 to 0.014) and heart disorders (lumpy sensation in the throat, chest pain; p=0.0001 to 0.042). When the sum score of health complaints was controlled for selected confounders, being female (B=-3.44, p=0.0001) and having excessively long working hours (B=2.76, p=0.0001) were significantly correlated with health complaints. In a separate gender analysis, being exposed to excessively long working hours remained a significant predictor for health complaints among both females (B=3.78, p=0.001) and males (B=2.28, p=0.004). Conclusions: Excessively long working hours are associated with an increased risk of health complaints. Reducing working hours may be the first step to improving physicians' health.
