Abstract PDF Supplementary Material: Objectives
This study was performed to investigate whether vestibular dysfunction affects health-related quality of life in Korean adults.

Methods
This retrospective cross-sectional study was performed with data from the 2010 to 2011 Korea National Health and Nutrition Survey for adults aged 40 years or more. The modified Romberg test and health-related quality of life evaluation using the EuroQoL 5-dimensional (EQ-5D) questionnaires were performed. Data were analyzed using a complex-sample chi-square test of independence and multivariate linear regression analysis. The main outcome measures were vestibular dysfunction and the calculated health-related quality of life questionnaire score.

Results
The overall prevalence of vestibular dysfunction was 3.4% (95% confidence interval, 2.5%–4.3%). In adults aged more than 40 years, multivariate linear regression analyses showed a significant reverse correlation between vestibular function and health-related quality of life since the EQ-5D index showed a lower score than normal (B coefficient=‒0.09, R²=0.299, p=0.003) for a decrease in balance function, and the scores for mobility, self-care, general activities, and pain/discomfort were worse, except for anxiety/depression. On the other hand, subjective dizziness was significantly associated with the EQ-5D index and all its subcategories.

Conclusions
Since adults with vestibular dysfunction have poor health-related quality of life, active monitoring and rehabilitation are necessary.

Objectives
This study was conducted to assess the current management status of the vestibular function test laboratories in Korea.
Methods
Questionnaire about the management status of the vestibular function test laboratories was sent by email to the entire members of the Korean Balance Society. The contents of questionnaire included situation of employees who perform the tests, the types of vestibular function tests and equipment, frequency of the test and types of dizziness related questionnaires.
Results
Forty-nine hospitals and clinics responded. All the 49 respondents answered that they have videonystagmography. Spontaneous nystagmus analysis by videonystagmogrphy was the most frequently tests for patients with dizziness. Questionnaires for dizziness were used by 27 respondents (55.1%) for initial evaluation of the dizziness patients. The Korean version of dizziness handicap inventory was the most frequently used dizziness related questionnaire. Conclusions: We analyzed the current management status of vestibular function test laboratories to comprehend the present condition of the vestibular function test. We think that these results will help to provide a standard for laboratory operations and prepare for the education, focusing on high-demand tests.

Abstract PDF: Background
and Objectives: To evaluate the prevalence and risk factors of subjective dizziness complaints in general population. Materials and Methods: A cross-sectional study was performed using data from The Korea National Health and Nutrition Examination Surveys. We evaluated data from 12,653 subjects who were interviewed between 2010 and 2012. Results: The prevalence of subjective dizziness was 21.7%. Female gender (adjusted odds ratio, AOR=1.959; 95% confidence interval [CI], 1.680?2.284; p＜0.001), lower alcohol consumption (reference ≤1 time a month; 1?4 times a month [AOR]=0.844, 95% CI=0.752? 0.948; ≥2 times a week, AOR=0.812, 95% CI=0.705?0.935, p=0.002), higher stress (AOR=1.784, 95% CI=1.613?1.973, p＜0.001), lower income (reference=lowest; middle low, AOR=0.815, 95% CI=0.720?0.923; middle high, AOR=0.696, 95% CI=0.606?0.799; highest, AOR=0.682, 95% CI=0.594?0.784, p＜0.001) increased odds ratio of subjective dizziness, while body mass index and smoking was not associated with subjective dizziness. Conclusion: This large population-based study provides reliable information about the prevalence and risk factors of subjective dizziness of Korean population.
