To date, only limited clinical evidences exist upon the association between sodium preference and OAB symptoms. This cross-sectional study analyzed the association between sodium preference and the severity of OAB symptom in men Methods: A total of 115578 female participants among total participants of 228921 in Korean Community Health Survey (KCHS) were included for analysis. To investigate the relationships among OABSS and salty taste preferences, and socioeconomic status simultaneously, a joint correspondence analysis (JCA) was performed. To graphically represent a result from JCA, the coordinate plot was generated. Subsequent analysis for salty taste preferences (blandly, neutral, and salty) also performed. To investigate the association between sodium preference and OABSS, multiple binomial regression analysis was performed. Results: Both severe and moderate OABSS were associated with preferences for salty taste, older age (70 or above), lower education level or household income, being separated, widowed, or divorced. The clustering of older age (70 or above), lower education level or household income, being separated, widowed, or divorced were retained across salty taste preferences subgroups. Both preference of salty taste group (high sodium preference) and non-salty taste group (low sodium preference) were significantly associated with higher OAB symptoms compared with neutral group (coefficient=0.187 (95% CI: 0.163-0.210) and coefficient=0.068 (95%CI: 0.044-0.093), respectively). Prediction of OABSS according to salty taste preference showed u shaped distribution. Conclusions: Sodium preference for taste was significantly associated with OAB symptoms. Both higher and lower intake of sodium could be unfavorable factor for severity of LUTS. keywords : Sodium intake, Overactive bladder symptoms
