IntroductionSystematic reviews by the WHO have shown an increased risk of morbidity and mortality related to ischemic heart disease and stroke among individuals working an average of ≥55 hours/week.MethodsA cross-sectional survey of U.S. physicians and a probability-based sample of the general U.S. working population (n=2,508) was conducted between November 20, 2020, and February 16, 2021 (data analyzed in 2022). Among 3,617 physicians who received a mailed survey, 1,162 (31.7%) responded; among 90,000 physicians who received an electronic survey, 6,348 (7.1%) responded. Mean weekly work hours were assessed.ResultsThe mean reported weekly work hours for physicians and U.S. workers in other fields were 50.8 hours and 40.7 hours, respectively (p<0.001). Less than 10% of U.S. workers in other fields (9.2%) reported working ≥55 hours/week compared with 40.7% of physicians. Although work hours decreased among physicians working less than full time, the decrease in work hours was smaller than the reported reduction in professional work effort. Specifically, for physicians who worked between half-time and full-time (i.e., full-time equivalent=50%-99%), work hours decreased by approximately 14% for each 20% reduction in full-time equivalent. On multivariable analysis of physicians and workers in other fields adjusting for age, gender, relationship status, and level of education, individuals with a professional/doctorate degree other than an MD/DO (OR=3.74; 95% CI=2.28, 6.09) and physicians (OR=8.62; 95% CI=6.44, 11.80) were more likely to work ≥55 hours/week.ConclusionsA substantial proportion of physicians have work hours previously shown to be associated with adverse personal health outcomes.Copyright © 2023 American Journal of Preventive Medicine.
