Abstract

Background and Objectives Benign paroxysmal positional vertigo (BPPV) is one of the mostcommon causes of dizziness with a high recurrence rate. This study aimed to analyze the recurrencerate and the risk factors for recurrence using the Korean National Health Insurance ServiceNational Sample Cohort (NHIS-NSC 2002-2013) data. Subjects and Method Patients aged 20 years or older who were diagnosed with BPPV inthe period of 2002-2012 and had at least 1 year of monitoring period were included in this study. The diagnosis of BPPV was made when the code for BPPV (KCD-6 code H811) was used orwhen canalith reposition therapy (EDI code MX035) was entered even in cases with differentdiagnoses. The risk factors of BPPV recurrence were analyzed. Results Of the total of 21355 patients diagnosed with BPPV, 5876 patients (28%) demonstratedrecurrence. Multiple recurrences were common. When using the univariate regression analysis,age, sex, vestibular disease, headache, osteoporosis, and ischemic heart disease were foundsignificant. When the patients were classified into 4 groups according to age and sex, vestibulardiseases were found as a common risk factor for recurrence in all groups, while headache,osteoporosis, hypertension, and ischemic heart disease were significant in females. Conclusion The recurrence rate of BPPV in the Korean adult population was approximately28% and recurrences were more common in patients aged over 65 and in females. Patients withvestibular diseases were at a higher risk of recurrence regardless of age or sex, while headache,osteoporosis, hypertension and ischemic heart disease increased the risk of recurrence in females.
