EXAMINATION OF THE EFFECT OF COMORBID DISEASES AND VITAMIN LEVELS ON SLEEP QUALITY

Abstract

AIM: The aim of this study was to investigate the relationship between comorbid diseases, vitamins levels and sleep quality of patients undergoing polysomnography (PSG) in a sleep clinic.
 MATERIAL AND METHODS: Fifty-four patients who underwent PSG between January 2018 and December 2018 at Bolu Abant İzzet Baysal Training and Research Hospital Sleep Clinic were included in the study. PSG measurements were performed in the sleep clinic following appropriate preparatory procedures.
 RESULTS: Of the study group, 41 (78.8%) were male and 11 (21.2%) were female. The mean age was 49.25 ± 12.77 years. The number of sleep apneas (p=0.013), central apnea (p=0.037), apnea / hypopnea index (p=0.026) and RDI (p=0.021) were higher in patients with diabetes melllitus (DM). It was found that REM sleep time was shortened in patients with hypertension (HT) (p=0.021) and patients with CAD (p=0.013). There was a positive weak correlation between vitamin D levels and stage 2 sleep duration (p=0.032, r = 0.309). As folate levels (p=0.039, r =-0.305) and vitamin B12 levels (p=0.035, r=-0.305) increased, arousal index values decreased.
 CONCLUSION: HT and CAD have very limited effects on sleep. In addition, DM most negatively affected sleep parameters in this study. It was also found that the evaluated vitamin levels affect sleep only very limited in some parameters.
