Abstract

Objective: The relationship between sleep quality and odor in medical faculty students was investigated.

Material-Method: Our study was approved by the clinical research ethics committee. In our cross-sectional study, socio-demographic characteristics questionnaire, Pittsburg sleep quality index (PUKI) and odor-sleep questionnaire were used to evaluate the sleep quality of the medical faculty students of our university.

Results: Our work; 91 (46.9%) female students and 103 (53.1%) male students were included. The mean age of the students included in the study is 21.91±1.94, the income level of the students is 79 (42.2%) 1000 TL and above, 87 (44.8%) people live in apartments, 149 (76.8%) people smoke and 143 (73.7%) people do not use alcohol. 165 (86.4%) of the participants preferred to sleep in a dark environment. Of the students participating in the study, 160 (82.9%) were noise, 149 (77.2%) light, 145 (75.1%) the temperature level of the environment, 122 (63.2%) were physically in bed. structure, 107 (55.4%) polluted environment and 106 (54.9%) bad smell of the environment affected their sleep quality. 89 (45.9%) people agreed with the relationship between smell and sleep, and 70 (36.1%) people agreed with the relationship between smell and memory. The mean of the total PUKI scale in our study was found to be 12.88±5.60. There was a statistically significant difference between the time to sleep in term I and II students (p=0.040), and it was found that the time to sleep was prolonged in term II students. There was a significant difference in the duration of falling asleep between the students who participated in our study, between the semester II and the third semester students (p=0.017). The sleep quality of the students included in our study during falling asleep was found to be statistically significant (p<0,05).

Conclusion: For a quality sleep, it is thought that there may be a connection between the smell and the sleep process.

Abstract

Amaç: Tıp Fakültesi öğrencilerinde uyku kalitesi ve koku arasındaki ilişkinin araştırılması planlandı.
Materyal-Metot: Çalışmamız klinik araştırmalar etik kurulu tarafından onaylandı. Kesitsel tipte olan araştırmamızda üniversitemizin tıp fakültesi öğrencilerine sosyodemografik özellikler anketi, uyku kalitesini değerlendirmeye yönelik Pittsburg uyku kalite indeksi (PUKI) ve koku-uyku anketi uygulandı.
Bulgular: Çalışmamıza; 91 (%46,9) kadın öğrenci ve 103 (%53,1) erkek öğrenci dâhil edildi. Çalışmaya dâhil olan öğrencilerin yaş ortalaması 21,91±1,94, öğrencilerin %42,2’sini (n=79) 1000 TL ve üzerinde kazandığı, 87 (%44,8) kişinin apartta kalmakta dığı, 149 (%76,8) kişinin sigara ve 143 (%73,7) kişinin alkol kullanmadığı tespit edildi. Katılımcılardan 165 (%86,4) kişi karanlık ortamda uyumayı tercih ettiğini belirtti. Çalışmaya katılan öğrencilerin 160 (%82,9)’ı gürültü, 149 (%77,2)’u ışık, 145 (%75,1)’i ortamın ısı düzeyi, 122 (%63,2)’si fiziksel olarak yatak yapısı, 107 (%55,4)’si ortamın kirli olması ve 106 (%54,9)’sı ortamın kötü kokması gibi faktörlerin uyku kalitelerini etkilediğini düşünmekteydi. dü. Koku uyku arasındaki ilişkiye 89 (%45,9) kişi, koku ile hafıza arasında ilişkisine 70 (%36,1) kişi katılıyorum kesinlikle evet cevabını verdi. Çalışmamızdaki toplam PUKİ ölçeği ortalaması 12,88±5,60 olarak bulundu. Dönem I ve II öğrencilerinde uykuya yatış zamanı arasında istatistiksel olarak anlamlı fark vardı (p=0,040). Dönem II öğrencilerinde yatış zamanın uzadığı bulundu. Çalışmamıza katılan öğrencilerin dönem II ve dönem III öğrencileri arasında uykuya dalma süresinde anlamlı farklılık bulundu var (p=0,017). Çalışmamıza dâhil olan öğrencilerin uykuya dalma sırasındaki uyku kalitesi istatistiksel olarak anlamlı bulundu (p<0,05).
Sonuç: Kaliteli bir uyku için, koku ile uyku süreci arasında bir bağlantı olabileceği düşünülmektedir.
