“…Other research has not found such an association in terms of daytime sleepiness (Breslau et al, 1997) or the development of sleep problems (Linton, 2004). In studies that have considered psychosocial job stressors and shiftwork simultaneously, controlling for shiftwork did not reduce the associations between other stressors and sleep to non-significant levels (Frese and Harwich, 1984;Ota et al, 2005;Sekine et al, 2006;Utsugi et al, 2005), suggesting that shiftwork does not mediate the relationships between stressors and poor sleep quality. Although we did not have a direct measure of shiftwork, we conducted an additional analysis using a proxy measure of the percentage of workers in the respondent's occupation that worked non-standard hours, based on information from the US Bureau of Labor Statistics (2005; not shown but available from the authors).…”

“…Similar results were reported by Pelfrene et al (2002) in a study of Belgian workers. Recent research in samples of Japanese workers has also suggested that job demands and job strain are associated with sleep related problems (Ota et al, 2005;Sekine et al, 2006;Utsugi et al, 2005).…”

“…Numerous studies have been conducted in Japan (Doi, 2005;Doi et al, 1999;Nakata et al, 2004;Nakata et al, 2000;Ota et al, 2005;Sekine et al, 2006;Utsugi et al, 2005), Finland (Urponen, Vuori, Hasan, & Partinen, 1988), Sweden (Linton, 2004), Germany (Frese & Harwich, 1984), Belgium (Pelfrene et al, 2002), and France (Ribet & Derrienic, 1999). There may be international differences in the significance and magnitude of associations due to variations in cultural contexts.…”

Given the associations between poor quality sleep and health, it is important to consider whether job stressors are related to sleep-related outcomes. Studies from Europe and Japan suggest that these stressors negatively impact sleep, but there are few studies of job stressors and sleep quality that draw upon large representative samples of workers in the USA. Using data collected via telephone interviews from a nationally representative random sample of 1,715 American full-time employees, this research considers three dependent variables of past-month poor sleep quality: number of days the respondent had difficulty initiating sleep, number of days of difficulty maintaining sleep, and number of days of non-restorative sleep. Negative binomial regression was used to estimate a count data model of the associations between the frequency of these three types of poor sleep quality and the job stressors of work overload, role conflict, autonomy, and repetitive tasks, while controlling for socio-demographic characteristics. The average American worker reported 5.3 days of difficulty falling asleep, 6.6 days of trouble staying asleep, and 5.0 days of trouble waking up for work in the past month. Across the three types of poor sleep quality, work overload was positively associated with the frequency of poor sleep quality. Role conflict was positively associated with difficulty initiating sleep and non-restorative sleep. Repetitive tasks were associated with more days of difficulty initiating sleep and maintaining sleep. Job autonomy was negatively associated with nonrestorative sleep. Given that sleep quality is associated with other health outcomes, future research should continue to explore the associations between job-related stressors, sleep quality, and workers' health status.

“…In this study as well, those with high job demand appeared to experience insomnia 1.30 times more frequently than those with low job demand. Akerstedt et al 29) reported that high job demand caused sleep disorders in Swedish workers, and studies on Japanese workers using Karasek's DCM model also reported that job demand and job strain are related with sleep disorders including insomnia 13,14,30,31) . Nomura et al 32) also reported that the frequency of insomnia experience was only half in those whose job control was above average.…”

“…For example, shift work is a well-known occupational risk factor for insomnia, and there is emerging evidence that individuals with shift work are at higher risk for lack of sleep 7,11) . Job stress has also been suspected to be an occupational risk factor for insomnia with the evidence showing a significant relationship between job stresses and sleeping problems including insomnia [12][13][14] . Recent studies from Japan reported that the feeling useful to others in the workplace was negatively associated with sleep disturbance and workplace bullying mediated between job strain and sleep disturbance 15,16) .…”

ObjectiveWe aim to investigate the quantity and quality of scientific evidence dealing with comprehensive health issues of working women in occupational health.MethodsThis scoping review of original articles that investigated comprehensive health issues of working women aged 19–64 years in Japan was published in PubMed (1967–2022) and Igaku Chuo Zasshi (or Ichu‐shi, 1982–2022). Using identical broad search terms, we first identified 17 122 English and 6154 Japanese articles. We excluded those with clinically relevant topics, or ethnicity other than Japanese and included 853 English and 855 Japanese articles for review and classified them into nine research areas considered to be critical factors for women in the workforce and five study design groups to investigate the quality of the evidence accumulated.ResultsAmong 853 English‐language articles in PubMed, “Mental health” was the most frequent area studied, followed by “Work‐related disease” and “Lifestyle‐related disease.” Among 855 Japanese‐language articles from Ichu‐shi, “Mental health” was the most frequently studied area followed by “Work and balance,” and “Work‐related disease.” “Infertility, pregnancy, and childbirth” and “Menstruation, menopause, and genital disease” were well studied in Ichu‐shi but scarcely published in PubMed. “Harassment and discrimination” were sparsely reported in both databases. As for research designs, many articles in both PubMed and Ichu‐shi employed descriptive or cross‐sectional study designs. However, a few studies employed cohort/longitudinal or interventional studies.ConclusionThe results underscored the need for higher‐quality study designs with more scientific evidence on working women's health in the field of occupational health.
