This study was conducted for the purpose of identifying factors effecting sleep quality among female university students as well as the strength of the correlation for use as a basic reference for examining useful methods for alleviating sleep problems.
Method
A questionnaire survey targeting 1077 female university students was conducted. The survey analysed variables such as Pittsburgh sleep quality index (PSQI), frequency of going to sleep at different times, frequency of waking up at different times, diet, exercise, degree of sensitivity to cold, and anxiety (HADS).
Results
The average age of the subjects was 20.3 years (SD = 1.3), PSQI scores averaged 6.3 (SD = 2.6); sleep problems for first and second year students averaged 70% compared with 50% for third and fourth year students. Although third and fourth year students indicated a greater regression of sleep phase in comparison with that of first and second year students, these students received approximately 40 min more sleep time. When a multiple regression analysis was conducted using PSQI (sleep quality) as a dependent variable, the factors affecting sleep quality among first and second year students were: HADS anxiety score, frequency of sleeping at different times, frequency of waking up at different times, and frequency of eating breakfast. Among third and fourth year students, HADS anxiety score, frequency of sleeping at different times, and frequency of waking up at different times affected sleep quality.
Discussion
Ensuring greater regularity with respect to sleeping at a certain time each day, adjusting the wakeup time to coincide with time of sleeping, adjusting biological rhythm by eating breakfast, and improving mental health were considered to be effective for improving sleep quality among female university students., 論文},
