Gender Differences with Regard to Perceived Job Insecurity and Insomnia in a Working Population

Objectives:Insomnia is one of the most prevalent disorders, and it is associated with various factors. Therefore, this study aimed to examine the association between perceived job insecurity and insomnia.Methods:Multiple logistic regression analysis was used to examine the association between three levels of perceived job insecurity and insomnia using the 2017 Korean Working Conditions Survey.Results:Approximately 10.2% of the total study population has insomnia. The higher the perception of job insecurity, the greater the chance for insomnia in both men (odds ratio = 4.03, 95% confidence interval [CI] = 3.18 to 5.11) and women (odds ratio = 4.44, 95% CI = 3.41 to 5.77).Conclusion:These findings reveal the sex differences in insomnia, thus suggesting the need to implement different approaches to deal with perceived job insecurity based on sex.
