is caused by complicated mechanism of ageing in addition to general etiologies as cerebrovascular disease, vestibular dysfunction, systemic and psychotic disease. The previous studies in Korea was based on the data from patients who visited hospital because of dizziness and there was no study about prevalence and its associated factors of dizziness in community-dwelling elderly populations. Methods.– Data were obtained from the Fourth Korea National Health and Nutrition Examination Surveys, which took place from January to December in 2008. A total of 793 participants aged 65 or older who answered questionnaire about dizziness were included. Results.– Two hundred and sixty-eight subjects (33.8%) complained of dizziness and 24.4% of dizzy persons reported falls over the past year. The prevalence was significantly higher in women (72.8% female, P<0.001). Dizziness was associated with chronic renal failure (P=0.02), cataract (P=0.003), depression (P<0.001) and hearing impairment (P=0.06) and stress (P<0.001). TheOdds ratios for factors in multiple logistic regression analysis were 1.03 (95% CI, 1.00 to 1.07) for age, 1.02 (CI, 1.00 to 1.03) for pulse rate, 1.44 (CI, 10.2 to 2.04) for cataract, 1.78 (CI, 1.19 to 2.66) for depression, 1.72 (CI, 1.18 to 2.49) for stress, and 1.42 (CI, 1.01 to 2.02) for hearing impairment. Conclusion.– The prevalence of dizziness in community-dwelling elderly population was 33.8% and higher in women. Furthermore, the factors associated with dizziness were age, rapid pulse rate, cataract, depression, stress and hearing impairment.
