Frequency of job stressors, difficulty unwinding after work, and sleep problems among urban transit operators

“…Further research is needed to explicate the pathways that may result in greater sleep problems among female transit operators compared to their male colleagues. Sleep quality has been shown to decline with age (Hublin, Lehtovirta, Partinen, Koskenvuo, & Kaprio, 2017), but workers in the study's oldest age category (56+ years) were not at increased risk for often experiencing insomnia symptoms. This may be due in part to the healthy worker effect, the phenomena in which healthier individuals are more likely to be employed than unhealthier individuals, and are likewise more likely to continue working than those in poorer health (McMichael, 1976).…”

“…This single-item approach also does not allow us to identify the duration and intensity of insomnia symptoms and whether participant endorsements of sleep problems are indicative of an insomnia disorder diagnosis. Although numerous studies have used a single-item measure to assess sleep quality (Hale et al, 2009;Hale, Hill, & Burdette, 2010;Hublin et al, 2017;Kim & Lee, 2015;Sorensen et al, 2009), objective measurement of sleep quality and disturbance would strengthen the design, such as through the use of actigraphy.…”
