Objective: To describe the sleep parameters of latency,
total sleep time, wake after sleep onset, total time in bed
and sleep efficiency in healthy members of the faculty of
medical sciences.
Design and Methods: This study recruited 14 healthy adults between age 25–50 years, employed at the Faculty of Medical Sciences, with no known history of sleep disorders. Sleep parameters were assessed using Phillips Respironics Actiwatch-2® on non-dominant wrist from Monday to Thursday for two weeks. Participants were classified as good sleepers at a SE = 85% and as poor sleepers below this threshold. Descriptive statistics involved median and interquartile range (IQR) and frequencies. Medians were compared using the Mann-Whitney U test and considered significant at p < 0.05.
Results: Nine females and five males completed the study with median age of 37[17] years. On average SL was 17 minutes, WASO was 53 minutes, TST was 377 minutes and TIB was 453 minutes. Females spent a significantly longer time in bed (p = 0.007) and slept longer (p = 0.012) than males. We found that 71.4% of participants exhibited poor SE (< 85%) and 78.6% were sleeping for < 7 hours, despite being in bed for > 7 hours. Poor sleepers also had significantly longer WASO durations over the study period. No participant reported any medication use.
Conclusion: Most (71.4%) staff members from the faculty of medical sciences were poor sleepers with SE < 85%, who were sleeping for < 7 hours nightly due to increased WASO durations. TIB and TST were significantly longer for females than males.
