DETERMINANTS OF POOR SLEEP QUALITY AMONG EDUCATIONAL WORKERS

Abstract

Background: In educational workers, poor sleep quality has a major impact on health and productivity. Although there are many known risk factors for poor sleep quality, data on these risk factors in Indonesian educational workers are lacking. Therefore, this study aims to determine the most influential risk factors for poor sleep quality in Indonesian educational workers.

Methods: An observational analysis study with a cross-sectional design was conducted in October-December 2020 involving 81 participants at Yayasan Pendidikan Pelita Raya, Jambi.  Sleep quality, vitamin D intake, and job stress were measured using the Pittsburgh Sleep Quality Index (PSQI), Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ), and Health & Safety Executive questionnaires (HSE), respectively. Data analysis was done by multiple logistic regression, with a significant level of p <0.05.

Results: The median age was 29 (range 21-55) years, poor sleep quality was found in 30 (37%) participants, 42 (51.9%) of participants had low vitamin D intake, and 48 (59.2%) reported moderate-to-high stress levels. Age < 30 years (p < 0.040), moderate-to-high stress level (p < 0.013), and low vitamin D intake (p < 0.003) were significant associated risk factors for sleep quality in educational workers, with low vitamin D intake being the most influential risk factors.

Conclusion: Younger age, stress level, and low vitamin D intake were determinants of poor sleep quality in educational workers, with low vitamin D intake being the most influential risk factors. Management of stress and vitamin D intake are needed to improve sleep quality in educational workers.
