RESUMO

OBJECTIVES: The daily activities and performance of the working population can be threatened by sleep disturbances, including insomnia. This study evaluated the sleep patterns, sleep problems, daytime sleepiness, and lost productivity time (LPT) resulting from sleep quality and sleep duration issues among workers. METHODS: The Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), and the Health and Work Performance Questionnaire (HPQ) were completed by 653 workers in an urban area. Statistical analyses were performed using independent t-tests. RESULTS: The average sleep duration among the subjects was 6 h 37 min. While 19.6% of the subjects complained of poor sleep quality, 53.4% were affected during the day by insomnia. The estimated annual cost of LPT due to presenteeism (Won13,892,545 vs. Won11,840,140 ; p=0.033) and the total annual cost of LPT (Won14,040,968 vs. Won11,961,302 ; p=0.032) were higher in poor sleepers than in good sleepers. Furthermore, workers with a shorter sleep duration had a higher annual LPT due to presenteeism (747.83 vs. 648.57 h ; p=0.046) and a higher total annual LPT (754.48 vs. 657.99 h ; p=0.049) than workers with a longer sleep duration. CONCLUSION: Sleep deprivation among workers caused 1 h 51 min LPT per week. This suggests that sleep disturbance affects workers' performance in an organization, as well as in terms of individual health.
