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.

Dizziness is the most common symptom in elderly patients and has been identified as a risk factor for falls. They can affect objectively the ability to achieve a stable gaze, posture, and gait. Research on the relationship between vestibular hypofunction and falls in elderly people has been rarely performed and the evidence is controversial. Because falls result from various combinations of many factors, validated tools should be used for assessment of falling. Many of the tests and numerous parameters associated with the risk of falling have already been introduced, however guidance on which test is most appropriate for use in a specific setting still lack in the medical community. Therefore, developement of comprehensive fall risk management guideline and assessment tool including physical, psychosocial, environmental factors are necessary to prevent falls in the elderly. Establishment of validity and reliability for relationship among several vestibular function test are more important to evaluate efficiently risk of falls in the dizzy patients. Also we can expect that decreasing risk of fall when conduct the developement of additional customized intervention method using verified assessment tools.

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.
