“…Shift work induces sleep problems (25). Furthermore, there is an increase in working hours with an increase in mental workload (26,27). Our data also showed that the prevalence of long working hours and having severe mental workload and the proportion of shift workers were the highest in the shorter sleep duration group.…”

“…In the Netherlands [29] and the United Kingdom [35], the groups with the highest educational level accounted for the greatest proportion of long working hours. In Korea, the result was different: among workers who reported excessively long working hours (≥60 h/week), professionals with lower educational levels predominated [36]. Among women in Norway, no association between long working hours and educational level was observed.…”

Background: Health personnel are key players in developing and improving healthcare systems, caring for individuals and their communities, and helping improve quality of life. However, these professionals are often exposed to long working hours because of the pressing need for their services at potentially any time of day. The long working hours they endure are a major risk factor for both acute and chronic health problems. The present study aimed to analyze occurrences of long working hours and their association with individual characteristics and employment factors among workers in the municipal healthcare system in Belo Horizonte, Brazil. Methods: In this cross-sectional study, a ramdomly selected proportional sample of 1549 participants was analyzed from among the total of 13 602 workers in the Belo Horizonte municipal healthcare system in 2009. "Long" working hours were defined as >44 h/week. A self-administered questionnaire was used for accumulating data. Associations with outcomes were estimated using logistic regression, in univariate and multivariate models. Results: The rate of occurrence of long working hours was 31.4% (95% CI 29.1-33.7). Lower educational level (high school, technical, or uncompleted undergraduate [OR 0.60, 95% CI 0.47-0.78 p < 0.001], or elementary [OR 0.33, 95% CI 0.19-0.55 p < 0.001]) was associated with a lower likelihood of self-reporting long working hours in relation to the group with the highest educational level (completed undergraduate or postgraduate). Male sex (OR 1.62, 95% CI 1.26-2.09 p < 0.001), having children (PR 1.54, 95% CI 1.20-1.97 p = 0.001), and being in the healthcare provider group (OR 1.82, 95% CI 1.40-2.35 p < 0.001) were factors associated with greater likelihood of long working hours. Conclusions: It was observed that number of long weekly working hours was related to individual characteristics and employment factors.

“…The fifth mechanism is psychosocial stress related to long working hours. Long working hours may produce high job stress that could increase the risk of cerebrocardiovascular disease 22,27,28) . Many previous studies of the association between overwork and cerebrocardiovascular disease have adjusted for other risk factors, including age, gender, past medical history, body mass index, behavioral habits, socioeconomic status, and work-related factors 4,29) .…”

Overwork and cerebrocardiovascular disease in Korean adult workers: Tae‐Won JANG, et al. Department of Occupational and Environmental Medicine, College of Medicine, The Catholic University of Korea, Republic of Korea— Objectives Long work hours and overwork may increase the cardiovascular load of workers. But long work hours and overwork are not the same. Cardiovascular overload from working is dependent on the physical demand of the work and the worker's physical fitness, as well as the working hours. This cross‐sectional study was designed to identify the association between overwork and cerebrocardiovascular disease, taking into account the physical demand of work, physical fitness, and work hours. Methods Study data were obtained from surveillance of occupational cerebrocardiovascular disease. Questionnaire surveys including general and work‐related characteristics were conducted. Maximum acceptable work time was estimated using the physical work demand and physical fitness of the subjects. The overwork index, which was the ratio of maximum acceptable work time and actual work hours of the subjects, was calculated. Results In the workers with a moderate or high physical demand of work, the adjusted odds ratios for overwork indexes of 1.01−1.20, 1.21−1.50, and >1.50 were 2.679 (95% confidence interval (CI) 1.025−6.999), 3.124 (95% CI 1.111−8.783), and 4.331 (95% CI 1.719−10.908), respectively. Conclusions The results indicate that the risk of cerebrocardiovas‐cular disease might be high in the workers with long working hours, high physical demand of work, and poor physical fitness engaged in work with a moderate to high physical work demand. Work hours should be accommodated according to the worker's physical fitness and the physical demand of work, and this could lower the risk of cerebrocardiovascular disease.
