| Summary: | University students are more susceptible to insomnia due to the stress from academic, social and other physical
factors surrounding their studies. This study was conducted to ascertain and compare the prevalence of insomnia
and stress levels among the students from the Faculty of Health Sciences, Universiti Kebangsaan Malaysia, and
to study the association between stress and insomnia. Results from the Perceived Stress Scale (PSS) score found
that 79.01% of the respondents reported moderate stress, in which the highest stress level was found among the
3rd Year students with a mean PSS Score of 19.5 ± 5.36. No significant difference between the stress levels among
different academic years was detected. By utilising the Insomnia Severity Index (ISI), less than half of the students
were clinically insomniacs, in which 54.73% of the students reported no clinically significant insomnia while
32.10% and 13.7% suffer from subthreshold insomnia and clinical insomnia (moderate severity), respectively.
There exists a statistically significant difference (p<0.05) between the insomnia scores among different academic
years, with the highest mean ISI score obtained by 2nd Year Students (9.16 ± 5.68). The results indicate a medium
positive correlation between insomnia and stress level, as r= 0.33, p<0.001. The findings from this study will help
develop stress management strategies to maximise the quality and quantity of sleep among university students.
