“…Regarding gender differences, studies of diabetes (31), metabolic syndrome (32) and cardiovascular disease (33) point to possible different impacts by sex, while Wong et al (34,35) and Puttonen et al (36) have discussed aspects relating to work schedule. In a study of shift work and metabolic syndrome, Puttonen et al (36) pointed out that, although the reasons for the observed gender differences are not completely known, the characteristics of the working conditions of men and women may influence the associations found.…”

This gender-specific analysis showed different patterns of association between night work and diabetes for men and women. Results suggest that the effect of exposure to night work appears to take longer to manifest itself among men, highlighting the greater chances of developing diabetes particularly among female night workers.Affiliation: National School of Public Health, Oswaldo Cruz Foundation -ENSP/FIOCRUZ, Brazil.

“…Since the IARC decision, several meta-analyses have been published, one supporting the association between shift work and breast cancer (3) and two reporting inconclusive evidence (4,5). Aside from potential cancer risks, shift workers also experience increased incidence of chronic illnesses including cardiovascular disease, diabetes, and metabolic syndrome (a combination of obesity, dyslipidemia, high cholesterol, and insulin resistance) (6), as well as gastrointestinal disorders (7), workplace injuries (8), and disruption of family and social life (9).…”

The following articles refer to this text: 2014;40 (6) 543Review Scand J Work Environ Health. 2014:40(6):543-556. doi:10.5271/sjweh.3445 Health-related interventions among night shift workers: a critical review of the literature Objectives Associations between shift work and chronic disease have been observed, but relatively little is known about how to mitigate these adverse health effects. This critical review aimed to (i) synthesize interventions that have been implemented among shift workers to reduce the chronic health effects of shift work and (ii) provide an overall evaluation of study quality.Methods MeSH terms and keywords were created and used to conduct a rigorous search of MEDLINE, CINAHL, and EMBASE for studies published on or before 13 August 2012. Study quality was assessed using a checklist adapted from Downs & Black.Results Of the 5053 articles retrieved, 44 met the inclusion and exclusion criteria. Over 2354 male and female rotating and permanent night shift workers were included, mostly from the manufacturing, healthcare, and public safety industries. Studies were grouped into four intervention types: (i) shift schedule; (ii) controlled light exposure; (iii) behavioral; and, (iv) pharmacological. Results generally support the benefits of fast-forward rotating shifts; simultaneous use of timed bright light and light-blocking glasses; and physical activity, healthy diet, and health promotion. Mixed results were observed for hypnotics. Study quality varied and numerous deficiencies were identified.Conclusions Except for hypnotics, several types of interventions reviewed had positive overall effects on chronic disease outcomes. There was substantial heterogeneity among studies with respect to study sample, interventions, and outcomes. There is a need for further high-quality, workplace-based prevention research conducted among shift workers.

“…A similar finding was reported in a recent Canadian study. 8 Further research is required to understand the degree to which the higher relative risk experienced by women is due to composition differences in occupational exposure time to evening and night work schedules between men and women, differences in the pace of work, levels of supervision and co-worker support during non-daytime work schedules for occupations that have a dominant gender composition, or differences in non-work roles and responsibilities that may expose women to greater risk of fatigue on evening or night work schedules.…”

“…A Canadian study found night shift work was associated with an elevated risk of occupational injury and estimated that the excess burden of work injury attributed to shift work was 14% for women and 8% for men. 8 A study based on the US National Longitudinal Survey of Youth (1987Youth ( -2000 examining the association between different shift work schedules and the incidence of self-reported work injury and illness in a sample of young adults aged [22][23][24][25][26][27][28][29][30] found that night, evening, rotating and irregular shifts were all associated with an increased risk of occupational injury or illness compared with regular day shifts. 7 Despite the high prevalence of shift work schedules in north America, limited information on work hours relative to the 24 h clock is available.…”

“…1 2 There is an extensive literature on the relationship between work hours (including shift work) and adverse consequences for workers' health [3][4][5] with consistent evidence of elevated risk associated with work schedules involving employment in the evening or night. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] These risks are generally understood to arise from the individual or joint influence of worker fatigue (due to sleep disturbance or long work hours) and typically lower levels of supervision and co-worker support during non-daytime work schedules.…”

Objective To estimate the rate of work injury over the 24 h clock in Ontario workers over 5 years (2004)(2005)(2006)(2007)(2008). Methods A cross-sectional, observational study of work-related injury and illness was conducted for a population of occupationally active adults using two independent data sources (lost-time compensation claims and emergency department encounter records). Hours worked annually by the Ontario labour force by time of day, age, gender and occupation were estimated from population-based surveys.Results There was an approximately 40% higher incidence of emergency department visits for work-related conditions than of lost-time workers' compensation claims (707 933 emergency department records and 457 141 lost-time claims). For men and women and across all age groups, there was an elevated risk of work-related injury or illness in the evening, night and early morning periods in both administrative data sources. This elevated risk was consistently observed across manual, mixed and non-manual occupational groups. The fraction of lost-time compensation claims that can be attributed to elevated risk of work injury in evening or night work schedules is 12.5% for women and 5.8% for men. Conclusions Despite the high prevalence of employment in non-daytime work schedules in developed economies, the work injury hazards associated with evening and night schedules remain relatively invisible. This study has demonstrated the feasibility of using administrative data sources to enhance capacity to conduct surveillance of work injury risk by time of day. More sophisticated aetiological research is needed to understand the specific mechanisms of hazards associated with non-regular work hours.
