Quality of Sleep and Quality of Life of Rotating Shift Industrial Workers

Sleep is a vital need for humans. Industrial workers are among the people who suffer from insomnia and sleep problems due to rotating shifts. Therefore, this study aims to investigate the relationship between sleep quality and the quality of life of industrial workers with rotating shifts.

234 industrial workers participated in this descriptive-cross-sectional study. Data were collected using a demographic information questionnaire, a short form of the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF), and the Pittsburgh Sleep Quality Index (PSQI). Data were analyzed with an independent t-test, Pearson's correlation coefficient, and one-way ANOVA test in SPSS statistical software version 24.

The mean and standard deviation of the age of participants was 31.6±5.7 years. The mean and standard deviation of WHOQOL-BREF and PSQI scores were 66.5±11.3 and 5.8±1.6, respectively. A significant relationship was also observed between the quality of sleep and workers' quality of life (r=-0.31). People with higher age and work experience had lower quality of sleep and quality of life. Also, women experienced lower quality of sleep and quality of life compared to men and married people compared to single people.

Considering the significant relationship between the quality of sleep and the quality of life of workers, it is suggested that managers and supervisors of industries and factories design the work schedule of workers in such a way that the quality of sleep of workers and consequently the quality of life improve.
