Abstract Background Students need quality sleep and regular feeding during an intensive training proces. The aim of this study was to determine the sleep quality of Faculty of Medicine students and whether there is a relationship between sleep quality and eating attitudes and habits. Methods In this cross-sectional study; a face-to-face questionnaire was administered to 352 students who attending Inonu University Medical Faculty between January and March of 2019. The sample group is stratified according to class sizes (total 1665 students. The sleep quality and eating behaviors of students were questioned. For purpose, Pittsburgh Sleep Quality Index (PUKI, developed by Buysse et al,1989), and Eating Attitude Test (EAT,developed by Garner et al 1982) was used to assess quality and disorders. Kolmogorov Smirnov normal distribution test, Mann Whitney U and Kruskal Wallis test were used in analysis of the data. Results The mean age of the students was 21.5 ± 2.5 and 54.3% were female and 45.7% were male and 25.0% smoked cigarette. 64.4% of the study group had normal body mass index. The median value of the PUKI (cut of point is 5.0 and under 5 is good) score by gender is similar with 6.0 (1.0-15.0). The median value of the PUKI score was 6.0 (1.0-16.0) in social media / internet users and 5.0 (1.0-13.0) in non-users. According to Internet / social media users before going to sleep, the difference is significant (p: 0.016). The difference between cigarette smoking and median value of PUKI was significant (p: 0.029). there was a difference between classes in favor of upper classes in terms of EAT values (p = 0,046). 12.2% of the students are at risk of Blumia and 10.8% are at risk of Anorexia. There was no significant but positive correlation between the PUKI and EAT (p = 0.074, r = 0.096). Conclusions In general, the students’ sleep quality and eating attitudes and habits were found close to the cut-off points accepted by the tests. But blumia and anorexia is significant. This study was supported by the Research Fund of the Inonu University (No. 1792) Key messages Social media / internet usage of students before going to sleep affects sleep quality significantly. Although 64.4% of the students have normal body mass index, eating disorders (bulumia and anorexia) risk are noteable.
