Glucose intolerance in an employed population.

Abstract

Differences in glucose intolerance within various occupational groups , i.e. laborers, clerks, and managers, and the related environmental factors were studied in ca. 9000 male workers of a certain factory. Age-and weight-adjusted prevalence rates of glucose intolerance were 3.2% in the laborers, 5.8% in the clerks, and 9.3% in the managers. In the managers, the total intake of calories was excessive for the amount of exercise expended ; food intake was relatively low in complex carbohy drates and high in animal fats. The clerks were characterized by a high sugar intake. The low prevalence of glucose intolerance in the laborers was ascribed to the greater amount of exercise. Assigned work hours, however, probably affected the prevalence of diabetes in the laborers, which was 2.1% in subjects who worked all three shifts, but 0.9% in subjects working only day shifts. Thirty laborers from all 3 shifts consented to give urine specimens during their working time (8 hr), after the same amount of food and exercise in all of them. Urinary excretionn of HGH and VMA during the midnight shift was significantly higher (p <0.05) than that during the day shift although urinary 170HCS was significantly low (p <0.01) at midnight. There were no significant changes in urinary CPR excretion between day and night shifts. These data indicate the importance of environmental factors, such as exercise, nutrition and stress, in glucose intolerance. occupation ; diabtes mellitus ; shift workers ; stress ; urinary human growth hormone

Total mortality and cause-specific mortality of Swedish shift- and dayworkers in the pulp and paper industry in 1952-2001

“…Kawachi et al (10) reported an increased prevalence of diabetes in relation to years of nightwork in a cohort study of nurses. In a cross-sectional Japanese study (11) it was observed that diabetes was more common among three-shift workers than among dayshift workers. Another recently published cross-sectional study from Japan did not find differences between shiftworkers and dayworkers (12).…”

Shift work and metabolic syndrome, diabetes mellitus and ischaemic heart disease

“…It was mediated by body weight, while job strain was unrelated to type 2 diabetes risk [26]. Mikuni et al reported a higher prevalence of diabetes mellitus among shift workers [27]. Morikawa et al study suggests that shift work is a risk factor for the onset of diabetes mellitus and that there are different risks associated with different types of shift schedule [28].…”

Relationship between Food Intake and Sleep Pattern in Healthy Individuals

“…30,31 These disorders probably occur because sleep plays an important role in the metabolic control of the body. 10,11 Therefore, alterations in the quantity and quality of sleep lead to hormonal disturbances; these might be capable of altering the physiological homeostasis and consequently generate diseases.…”
