OBJECTIVE: To report the nationwide prevalence of @entity1296 and @entity394 in the Korean population and determine the associated factors. DESIGN: Cross-sectional analysis of a nationwide health survey. METHODS: We obtained data from the 2009 to 2010 Korea National Health and Nutrition Examination Surveys, which were cross-sectional surveys of the South Korean civilian, non-institutionalised population aged 40   years and older (N=3267). A field survey team performed interviews and physical examinations. Structured questionnaires were handed out and balance function tests using the modified Romberg test of standing balance on firm and compliant support surfaces were performed on @entity1 . Failure on the modified Romberg test was regarded to indicate @entity394 . RESULTS: The prevalence of @entity1296 during the past year was 16.70% (95% CI 14.65% to 18.76%). The presence of @entity394 was noted in 1.84% (95% CI 1.18% to 2.51%). In addition, the prevalence of experiencing falls and positional @entity1296 were 1.46% (95% CI 0.87% to 2.06%) and 1.73% (95% CI 1.17% to 2.29%), respectively. Multivariable analysis revealed that @entity1296 was associated with increased age, female gender, @entity393 and stress. @entity394 was associated with increased age, history of @entity1296 and @entity393 . CONCLUSIONS: Vertigo and @entity1296 are the greatest contributors to the @entity717 in the aged population. Screening for @entity1296 and @entity394 , and management of associated factors might be important for improving compromised quality of life due to postural imbalance caused by vestibular problems.
