Objective To investigate the clinical characteristics and outcome of benign paroxysmal positional
vertigo (BPPV).
Methods A total of 1046 cases of BPPV who were diagnosed with BPPV and got cured by canalith
repositioning maneuver (CRM) in the Beijing Tiantan Hospital of Capital Medical University from
July 2009 to June 2015 were enrolled. All the patients were followed up since December 2015, with
the aim of determining the outcomes. All data were analyzed and compared by using SPSS 22.0.
Results ①The prevalence of BPPV increased among women, with peak onset between 50 and 60
years of age and a female-to-male ratio of 2:1. ②The recurrence rate of BPPV was 27.20%. According
to Logistic regression multivariate analysis, recurrences were seen significantly more often in patients
with Meniere's disease (15.567 times, P <0.001), migraines (3.003 times, P <0.01), hypertension (1.554
times, P <0.05) and hyperlipidemia (1.457 times, P <0.05).
Conclusion BPPV is commonly seen in mid-aged patients with women higher than men. PSCBPPV
was the majority. Meniere's disease, migraines, hypertension and hyperlipidemia might be
the risk factors for BPPV recurrence.
