Association between increased daytime sleepiness and severity of obstructive sleep apnea

Cilj istraživanja: Osnovni cilj istraživanja bio je utvrditi postoji li povezanost između povećane dnevne pospanosti i stupnja težine opstruktivne apneje u spavanju (OSA). Ostali ciljevi bili su ispitati pojavnost OSA-e s obzirom na spol, ispitati postoji li povezanost indeksa tjelesne mase i stupnja težine OSA-e, te ispitati postoji li razlika u povećanoj dnevnoj pospanosti s obzirom na spol. Nacrt studije: Istraživanje je ustrojeno kao presječno istraživanje. Ispitanici i metode: U istraživanju je sudjelovalo 25 ispitanika kojima je polisomnografijom postavljena dijagnoza OSA-e i određen stupanj težine bolesti (AHI). Kao instrument istraživanja korišten je anonimni anketni upitnik kojim su ispitani demografski podaci i klinička obilježja bolesnika, a dnevna pospanost procijenjena je pomoću Epworthove i Stanfordove ljestvice pospanosti. Rezultati: U ovom istraživanju sudjelovalo je 20 (80 %) muškaraca i 5 (20 %) žena. Rezultati Epworthove ljestvice pospanosti pokazuju da 10 (40 %) ispitanika ima blago prekomjernu dnevnu pospanost, umjereno prekomjernu dnevnu pospanost ima 6 (24 %) ispitanika, a tešku prekomjernu dnevnu pospanost im 8 (32 %) ispitanika. Stupanj težine OSA-e osim što je povezan s povećanom dnevnom pospanosti, u značajnoj je vezi s indeksom tjelesne mase. Rezultati pokazuju da nema značajne razlike u povećanoj dnevnoj pospanosti s obzirom na spol. Zaključak: Temeljem rezultata istraživanja možemo zaključiti da postoji povezanost povećane dnevne pospanosti i stupnja težine OSA-e. OSA je češća u muškog spola. Postoji povezanost indeksa tjelesne mase i stupnja težine OSA-e. Nema značajne razlike u povećanoj dnevnoj pospanosti s obzirom na spol.Objectives: The main aim of this study was to examine whether there is a relation between increased daytime sleepiness and severity of obstructive sleep apnea (OSA). Other aims were examine whether OSA is more common in men or women, whether there is a relation between body mass index and severity of OSA and whether there is a gender difference in excessive daytime sleepiness. Study Design: This is a cross-sectional study. Material and Methods: This study involved 25 patients who performed full-night polysomnography at the Clinic of Neurology of the Osijek Clinical Hospital Centre and were diagnosed with OSA. Polysomnography determined severity of OSA (AHI). Patient's demographic data and clinical features were collected with an anonymous questionnaire. Excessive daytime sleepiness was estimated with the Epworth and Stanford Sleepiness Scale. Results: There were 20 (80 %) male and 5 (20 %) female patients with OSA in this study. The Epworth Sleepiness Scale scores showed that 10 (40 %) patients suffer mild excessive daytime sleepiness, 6 (24 %) patients suffer moderate excessive daytime sleepiness and 8 (32 %) patients suffer severe excessive daytime sleepiness. Severity of OSA is significantly associated with increased daytime sleepiness and body mass index. Results showed no significant difference in excessive daytime sleepiness between men and women. Conclusion: Based on the results of this study we can conclude that there is a relation between increased daytime sleepiness and severity of obstructive sleep apnea (OSA). OSA is more common in men. There si also a relation between severity of OSA and body mass index. There is no significant difference in excessive daytime sleepiness between men and women
