摘要
Objective: Despite the availability of highly effective treatments, there is a significant recurrence rate of benign paroxysmal positional vertigo (BPPV). This study is aimed to quantitatively measure sleep quality in BPPV patients and correlate it with the recurrence of BPPV. Methods: In this longitudinal cohort study, the clinical records of 67 elderly or middle-aged adult patients who were diagnosed with BPPV at Neurology Clinic, Beijing Chaoyang Hospital affiliated to Capital Medical University between 2013 and 2014. The 'recurrent' and 'non-recurrent' BPPV were respectively defined. Primary data collection included the medical history, blood test and Pittsburgh Sleep Quality Index measurement. Results: Among the total 67 patients after successful treatment, recurrent BPPV is observed in 37.31% patients (n = 25) within 2 years. Among all 11 variables analyzed between recurrent and non-recurrent groups, only the Pittsburgh Sleep Quality Index (PSQI) scores showed significant difference (p<.001). In details, these differences were also measured in five individual sleep items, including the subjective assessment of sleep quality, sleep latency, sleep duration, the use of sleep-aid medication and daytime dysfunctions (all p<.05). Regression analysis showed patients with higher PSQI score (lower sleep quality) had higher risk of BPPV recurrence [odds ratio (OR)=1.17, 95% confidence interval (CI): 1.04-1.32, p=.0082]. Conclusions: The sleep quality in patients with BPPV recurrence is significantly poorer compared to non-recurrent patients. Our result suggested sleep quality as measured by PSQI is an independent risk factor of BPPV recurrence.
