“…Other recent evidence suggests that shiftworkers take smaller amounts of energy and nutrients than day workers (13), although findings demonstrating changes in the circadian distribution of food intake, but not in total 24-hour consumption, have also been reported (14). Taken together, these results suggest that changed eating habits, and other life-style changes (including reduced exercise), among night shift workers may lead to increases in BMI, which, in turn, contribute to the higher levels of hypertension (15) and cardiovascular risk (16)(17)(18) associated with day-night shift work. However, the biological mechanisms that underlie observed relationships between shift work and cardiovascular risk have, as yet, not been clearly established (19).…”

“…org) gives information about job strain (specifically) and work stress (in general).] One plausible pathway between job strain and heart disease is elevated blood pressure (166), possibly mediated by increases in catecholamines and cortisol (167), increased autonomic nervous system activity (eg, increased heart rate), or increased mass of the heart's left ventricle (168). Extensive evidence is not available showing that stressful work conditions and psychosocial personal characteristics contribute to the development of coronary dysfunction and diseases via sustained autonomic nervous system activation.…”

Objectives This study attempts to estimate the proportion of annual deaths related to occupational factors in Finland and considers related methodological issues and associated uncertainties.Methods Statistics on causes of death, numbers of subjects exposed, and risk ratios obtained from the epidemiologic literature were used to estimate the population attributable fraction and disease burden for causes of death from work-related diseases. Gender-, age-and disease-specific numbers of deaths were provided by Statistics Finland for 1996. Information on the size of the population, broken down by gender, age, occupation, and industry, was acquired from population censuses. A Finnish job-exposure matrix supplied data on the prevalence of exposure for specific agents and the level of exposure among exposed workers. ResultsThe attributable fraction of work-related mortality in the relevant disease and age categories was estimated to be 7% (10% for men and 2% for women), and for all diseases and ages the fraction was 4%. For the main cause-of-death categories, the attributable fraction became 12% for circulatory system diseases, 8% for malignant neoplasms, 4% for respiratory system diseases, 4% for mental disorders, 3% for nervous system diseases, and 3% for accidents and violence. The following estimates were obtained for specific important diseases: 24% for lung cancer, 17% for ischemic heart disease, 12% for chronic obstructive pulmonary disease, and 11% for stroke. Based on these fractions, the total number of work-related deaths that occurred in Finland in 1996 was calculated to be on the order of 1800 (employed work force of 2.1 million); 86% involved men.Conclusions High-quality epidemiologic studies and national survey data are essential for obtaining reliable estimates of the proportion of deaths attributable to occupational factors. The magnitude of work-related mortality is an insufficiently recognized contributor to total mortality in Finland, especially from circulatory diseases and other diseases caused by exposure to agents other than asbestos.Key terms attributable fraction, burden of disease, epidemiologic methods, health statistics, occupational exposure. Global estimates of the burden of disease due to occupational factors have been calculated through the application of Finnish rates of registered work-related diseases (1). The approach is subject to the following two fundamental uncertainties: (i) the validity of the data on disease incidence from the national reporting scheme and (ii) the validity of worldwide extrapolations to different regions with different exposure circumstances. With the exception of studies using workers' compensation records, only a few research projects have estimated the magnitude of morbidity or mortality induced by exposure to hazardous agents or stress factors in the work environment at a state or national level. The investigations conducted in this area have covered New York State (2), the whole of the United States (3), Canada (4), and Australia (5). Given the lack of ...

“…Non-standard work hours (i.e. shift work) are thought to lead to poor health due to disruption in circadian rhythms and changes in lifestyles (39,40) , and have been associated with CVD (41,42) , hypertension (43) , gastrointestinal disorders (44) and cancer (45) . Work-related stress is also a significant concern in the labour force, and considerable research has focused on the link between work stress and poor health/well-being.…”
