Abstract

BACKGROUND AND OBJECTIVES
Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of dizziness with a high recurrence rate. This study aimed to analyze the recurrence rate and the risk factors for recurrence using the Korean National Health Insurance Service National Sample Cohort (NHIS-NSC 2002-2013) data.
SUBJECTS AND METHOD
Patients aged 20 years or older who were diagnosed with BPPV in the 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 or when canalith reposition therapy (EDI code MX035) was entered even in cases with different diagnoses. The risk factors of BPPV recurrence were analyzed.
RESULTS
Of the total of 21355 patients diagnosed with BPPV, 5876 patients (28%) demonstrated recurrence. Multiple recurrences were common. When using the univariate regression analysis, age, sex, vestibular disease, headache, osteoporosis, and ischemic heart disease were found significant. When the patients were classified into 4 groups according to age and sex, vestibular diseases 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 approximately 28% and recurrences were more common in patients aged over 65 and in females. Patients with vestibular 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.
