Prevalence of Sleep Quality among Academic Staff of a Private University in Malaysia

Abstract

Introduction: Poor sleep quality is frequently related to poor mental health and is a common medical disorder. It may differ by population, but limited studies have been done in Malaysia. This study was conducted to measure the prevalence of poor sleep quality among academic staff at Universiti Tunku Abdul Rahman (UTAR) Kampar Campus. Methods: In total, 344 randomly selected academic staff were approached to answer the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Results: Unexpectedly, 42.7 % of them were affected by poor sleep quality (global PSQI score >5). The average actual sleep duration was recorded at 6.68 hours. Age and global PSQI scores were not significantly correlated. Female staff had poorer subjective sleep quality (P= 0.027). The elder age group (P= 0.012) and associate professors and professors (P= 0.006) consumed more sleep medications. Non-Ph.D. holders had poorer subjective sleep quality (P= 0.008) and sleep latency (P= 0.032) as well as global PSQI score (P= 0.045) compared to Ph.D. holders. Conclusion: Prevalence of poor sleep quality was higher than expected among academic staff. This may affect workplace functioning and burden the staff with more health issues related to poor sleep quality.
