Lee, Eliza; Lee, Keum Jae

Abstract

PURPOSE
The purpose of this study was to identify quality of sleep and its influencing factor among middle-aged male workers.
METHODS
The subjects of this study were 411 middle-aged male workers living in Seoul and Gyeonggi-do. The data were based from self-reported using structured questionnaires asking about low urinary tract symptoms, circadian rhythm, quality of life and sleep quality including general characteristics. The data were collected from September 11 to October 31, 2013 and analyzed by t-test, one-way ANOVA, Pearson correlation coefficient and hierarchical regression.
RESULTS
Mean score of the sleep quality was 5.03+/-2.57 (range: 0~21) and reported as bad sleep quality in 55.7%. Low urinary tract symptoms (beta=.30, p<.001), circadian rhythm (beta=-.17, p<.001), quality of life (beta=-.14, p<.001) were shown as significant association of sleep quality.
CONCLUSION
Strategies to improve sleep quality in middle-aged male workers are necessary and nursing intervention should be developed to improve education program for prevention and management of low urinary tract symptoms. It is also necessary to legalize the institutional devices to upgrade work environment and to place regulations on overtime at work places in order for these workers to obtain sufficient sleep time for recovery of biological rhythms and improving sleep quality.
