Affecting Factors on Sleep Quality in Foreign Workers

Abstract

Objectives: This study aimed to identify effects of stressors and psychological adaptation of foreign workers on sleep quality.Methods: Data from 97 participants at the Busan Foreign Residents Center were included in the final analysis. The questionnaire consisted of sociodemographic characteristics, health behaviors, job related characteristics, stressors, psychological adaptation, and sleep quality. Hierarchical linear regression analysis was performed to identify factors affecting sleep quality using SPSS 28.0 program.Results: There was no significant difference in sleep quality according to demographic characteristics such as gender, age, and education. In the case of health characteristics, sleep quality was poor when current or past smoking and subjective health status were moderate or unhealthy. As a result of the correlation analysis among stressors, psychological adaptation, and sleep quality, sleep quality was positively correlated with family stress (r = 0.21, p< 0.05) and psychological adaptation (r = 0.34, p< 0.01). As a result of hierarchical linear regression analysis, non-smoking (β= -0.25, p< 0.05) and salary of 1.5 million won or more (β= -0.34, p< 0.001) were factors that improved sleep quality, while psychological adjustment difficulties (β= 0.33, p< 0.01) was a factor that deteriorated the quality of sleep.Conclusions: We confirmed that smoking status, wage level, and psychological adjustment are important factors affecting sleep quality. It is proposed to operate a comprehensive mental health program for improvement of sleep quality for foreign workers.
