“…2,5 In fact, several studies have indicated that the linkage between longer work hours and obesity is mediated by shorter sleep duration. [39][40][41] Interestingly, the younger drivers in our sample had higher odds for being overweight, obese, or extreme obese, which went against our hypothesis, but the review by Solovieva et al 17 also found that younger male workers were more likely to gain weight with increased work hours than older workers. With 70% of our sample working on average more than 11 hours daily (or an estimated 55 to 70 hours per week), this is comparable to Sieber et al's 20 findings of approximately 60 hours of weekly work among their national survey of US drivers.…”

“…Psychosocial factors at work and long work hours might increase the frequency of eating higher caloric value food (44), decrease physical activity (45), and reduce sleep (46,93). They may also increase the risk of weight gain and obesity directly through neuroendocrine pathways (40).…”

This is a systematic review of associations of psychosocial factors at work and long work hours with weight-related outcomes. Reviewed studies provide some evidence for associations between psychosocial factors at work and excess weight and between long work hours and weight gain. Cohort studies of high quality using appropriate analytical methods based on an elaborated hypothetical model are needed. Affiliation 241Review Scand J Work Environ Health. 2013;39(3):241-258. doi:10.5271/sjweh.3364 Psychosocial factors at work, long work hours, and obesity: a systematic review Objectives Associations between psychosocial work environment and excess weight have not been systematically addressed. The aim of this systematic review was to summarize the published evidence for the associations of psychosocial factors at work and long work hours with weight-related outcomes. MethodsWe conducted a search of Medline and Embase for all original articles published up to September 2012 using predefined keywords. After excluding studies with a definite selection bias, we included 39 articles.Results About 60% of the studies reported at least one positive association between psychosocial factors at work and a weight-related outcome. However, 76% of the tested associations were found to be non-significant. Furthermore, the associations were rather weak. Studies of higher quality tended to observe associations more often than those of lower quality. Positive associations were found more frequently (i) among women versus men, (ii) in cross-sectional versus longitudinal studies, and (iii) for overweight or obesity versus other outcomes. About 70% of the studies reported positive associations between long work hours and weight-related outcomes. All four studies that evaluated the association between working overtime and weight gain (three longitudinal and one cross-sectional), showed a positive association among men and two of them also observed associations among women. ConclusionsWe found evidence for weak associations between psychosocial factors at work and excess weight.Associations were observed between long work hours, working overtime, and weight gain, especially among men. More cohort studies among non-obese baseline participants using appropriate analytical methods based on an elaborated hypothetical model are needed.

“…Long work hours might interfere with various activities including sleep 12) , and disruption of the circadian rhythm could play a role in the development of metabolic problems such as obesity 24) . Magee et al 14) reported that long work hours were indirectly associated with high body mass index, and short sleep might mediate this association. Short sleep could also be associated with the changes in hormone levels such as leptin and ghrelin, which play an important role in the regulation of energy storage and the sense of hunger and satiety in the human body 25) .…”

“…Work-related factors such as work hours 12) and shift work 13) are also related to obesity. Long work hours might lead to weight gain through lack of exercise, undesirable eating habits, and reduced sleep hours 12,14) . The presence of gender differences in the association between work hours and obesity is controversial.…”

25 or over 64 years, pregnant women, part-time workers, soldiers, housewives and students were excluded. The total number of individuals included in the analysis was 8,889 (5,241 male and 3,648 female subjects). The outcome variable was obesity, defined as body mass index ≥25 kg/m 2 . Variables considered in the model were age, education, income, marital status, alcohol drinking, smoking, daily energy intake, physical activity, sleep hours per day, the type of job, work hours, and work schedule. Work hours were categorized as <40, 40−48 (reference), 49−60, and >60 hours per week. Results: In the multiple SURVEYLOGISTIC regression analyses, the adjusted odds ratio of obesity for long work hours (>60 hours per week) in male manual workers was 1.647 (95% confidence interval 1.262−2.151). Long work hours did not significantly increase the odds ratio for obesity in male nonmanual workers and female manual and nonmanual workers. Conclusions: More than 60 work hours per week increased the risk of obesity in Korean male manual workers. This result might be helpful in preventing obesity in Korean adult workers, especially male manual workers. (J Occup Health 2013; 55: 359-366)
