Abstract
Objectives
The objectives of the study were to assess the sleep quality of undergraduate students
in a Nigerian University, to determine its association with psychological distress,
and to evaluate some of the factors associated with poor sleep quality among the students.
Methods
It is a descriptive cross-sectional study conducted among the undergraduate students
of Obafemi Awolowo University, Ile-Ife. The multistage sampling method was used to
select 520 study participants, and a self-administered instrument including a questionnaire
on sociodemographic characteristics, Pittsburgh Sleep Quality index, General Health
Questionnaire, and Hospital Anxiety-Depression Scale was administered.
Results
Out of 520 students who gave consent to participate in the study, 505 students (97.1%)
returned a fully-completed questionnaire. Half of the students (50.1%; 95% confidence
interval [CI], 45.7-54.5%) had poor sleep quality, with a minority (5.7%) taking sleep
medications at least once or twice a week. About one-fourth (24.4%; 95% CI, 21.7-27.1%))
had psychological distress. Among the demographic factors, the year of study (χ2 = 13.80 [P < .01]) had significant association with poor sleep quality. Presence of psychological
distress and symptoms of depression and anxiety were also significantly associated
with poor sleep quality. The year of study, psychological distress, and anxiety symptoms
were significant predictors of poor sleep quality among the students.
Conclusion
The strong association between psychological distress and quality of sleep further
underscores the benefit of advocating for habits that can improve optimal mental health
and sleep quality among the undergraduate students.
