Associations of extended work, higher workloads and emotional work demands with sleep disturbance among night-shift workers

Abstract

Background In-depth investigation of the factors that exacerbate sleep disturbance among night-shift workers is essential to develop a successful implementation strategy to improve sleep. Although some characteristics of work associated with sleep disturbances have been investigated, there are inconsistencies in the findings. This study aimed to assess the influence of working time and work characteristics on sleep disturbance among night-shift workers. Methods This study was a secondary data analysis of a nationally representative sample of data from the fifth Korean Working Condition Survey in 2017. A total of 1,790 wage workers aged between 19 and 64 years with night shift schedules were selected and analyzed. A multiple logistic regression analysis was conducted to analyze the influences of working time characteristics, including shift type, frequency of night shift, and extended work; as well as work characteristics, including physical work demands, workload, emotional work demands, social support, and communication, on sleep disturbance among night-shift workers. Results Of those analyzed, 8.4% of night-shift workers experienced sleep disturbances. Night-shift workers with extended work, higher workloads, and emotional work demands were more likely to experience sleep disturbances (OR = 1.53, 95% CI = 1.05 to 2.23; OR = 1.01, 95% CI = 1.01 to 1.03; OR = 1.03, 95% CI = 1.02 to 1.05; respectively). Conclusion Extended work, higher workload, and emotional work demands were significant factors for sleep disturbance among night-shift workers. These findings highlight the importance of adjusting work demands and mitigating extended work to reduce sleep disturbance in night-shift workers.

Effectiveness of sleep interventions for rotating night shift workers: a systematic review and meta-analysis

“…The factors that have the highest influence on sleep disturbances might differ according to the characteristics of work and types of occupation ( 58 ). For example, extended work, higher workloads, and emotional work demands were factors that influenced sleep disturbances among all types of night shift workers in Korea ( 59 ), however, only the influence of emotional work demands and social support and not working hours or higher workloads was significant among night shift working nurses in Korea ( 60 ). Therefore, future sleep interventions must be assessed to determine the interventions that provide the best outcomes for each type of worker.…”

Association between high emotional demand at work, burnout symptoms, and sleep disturbance among Korean workers: a cross-sectional mediation analysis

“…Our study findings are consistent with previous research showing a significant association between EDW and poor mental health outcomes. Several previous studies have demonstrated that individuals with high EDW are at a greater risk of experiencing depression 6,9,36 or sleep disturbances 10,37 . Specifically among night shift workers 37 and customer service workers 10 in South Korea, high EDW was seen to be associated with sleep disturbance.…”
