The influence of sociodemographic and health‐related factors, clinical education status, and sleep quality on work‐related quality of life among dental students.

Introduction: With the premise that the demanding educational process and associated factors could influence the work‐related quality of life (WRQoL) of dental students, this study aimed to investigate the influence of diverse sociodemographic and health‐related factors, clinical education status, and sleep quality on the WRQoL of dental students. Materials and Methods: A three‐part questionnaire was administered to a group of preclinical and clinical dental students studying in different classes. The first part of the questionnaire included various sociodemographic and health‐related questions. In the second part, the multidimensional 23‐item WRQoL scale, with established validity and reliability, was applied to evaluate the WRQoL of the students. The last part of the questionnaire included the Pittsburgh Sleep Quality Index, comprising 19 items. General linear models were created to predict subscale scores using sociodemographic and health‐related characteristics, as well as univariate significant independent variables. Results: It was observed that the majority of the participants (78.2%) had poor sleep quality. Being clinical dental students had a significant and positive effect on the stress at work domain of WRQoL (p =.006), while it had a significant and negative effect on the home‐work interface domain (p <.001). The decrease in sleep quality had a significant and negative effect on all domains of WRQoL (p <.05) except for the stress at work domain. Conclusions: Clinical education status, regular smoking, and sleep quality significantly affect different domains of dental students' WRQoL. Changes in these factors should be considered in approaches to increasing students' WRQoL. [ABSTRACT FROM AUTHOR]
