Investigation of Sleep Quality and Sleep Disorders in Students of Medicine

Abstract

OBJECTIVES: This study was performed on Suleyman Demirel University medical students to determine the quality of sleep and to investigate factors that affect of sleep quality. MATERIAL AND METHODS:Suleyman Demirel University Medical students at 1, 2, 3, 4, 5 and 6 classes included to this crosssectional analytical study (n= 720).Refused to fill to the survey (188), and students were not come to faculty (195), applied survey to 337 students (46.8%).Epworth sleepiness scale (ESS), Pittsburgh (PSQI) and Berlin sleep questionnaires, and 13 pieces closed and open-ended socio-demographic questions were conduct a questionnare under observation.The collected data were analyzed by using descriptive statistics, chi-square, two independent groups t test, Pearson and Spearman's correlation, Mann-Whitney U, Kruskal-Wallis and ANOVA tests.RESULTS: 337 students participated in the study, 42.1% were male, 57.9% were female, mean age was 21.3 ± 2.1 years.Depending on Body mass index (BMI) 31 were poor, 212 normal, 53 overweight, and 4 obese students.In 118 students (35.3%), and these students have a chronic disease associated with 15.6% used the drug because of illness and 38 percent of students (11.6%) were smokers.18.1 ± 16.1 min for pupils in times of falling asleep, sleep duration per night.6.6 ± 1.3h, the mean departure time was 7.7 ± 1.8.Scale with a total score of Pittsburgh class (p= 0.000), age (p= 0.003), BMI (p= 0.015) had a significant correlation between.Pittsburgh PUKI scores and without a significant difference in gender (p= 0.054), the use of stimulant substances (p= 0.032), weight (p= 0.021) and snoring (p= 0.002) with no significant difference were found.ESS total score and gender (p= 0.025), drug use (p= 0.035) and sports activities (p= 0.038).Ten students had snoring (3.0%), 5 students (1.5%) had witnessed apnea.Snoring 17.2% to in ESS > 10 points on it.Pittsburgh, the mean scores of those who witnessed apnea (14.0 ± 5.3), witnessed apnea, according to non-students (10.2 ± 6.4) were higher (p= 0.191).The effects PSQI and ESS results on the term were statistically significant by the multivariate regression analysis [F(10.602)=4.56; p< 0.05; Wilkis Lamda 0.864, partial n 2 = 0.07].To estimate of the value of PSQI by the stepwise regression analysis was performed; age and fall asleep properties has been included of the model (R2= 89%, p< 0.05).To estimate of the value of PSQI by the stepwise regression analysis was performed; fall asleep property has been included of the model in the the male gender (R2= 80%, p< 0.05).To estimate of the value of ESS by the stepwise regression analysis was performed; term property has been included of the model (R2= 65%, p< 0.05).CONCLUSION: Medical school students participating in our study, although female-male ratio close to each other, we found that higher ESS and Pittsburgh scores in female more than male.In this case may be related to physiological, genetic, environmental, cultural and psychological differences.
