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 n2= 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. © 2016 by Turkish Thoracic Society.
