Abstract
In this study, we explore relationships between Subjective Well-Being (SWB), salt intake whose exces-sive intake is problem, and eating behavior of university students. For 122 university students, we investi-gated these relationships using the Subjective Well-Being Scale (SWBS), the Big Five personality traits (Big-V) from the Ten Item Personality Inventory (TIPI-J) and the items related to awareness of salt intake and eating behavior. As a result, we found the following findings by basic tabulation, correlation analysis, and modeling using structural equation modeling. (1) There is an association between SWB and Big-V as shown in previous studies. (2) Perceived high frequency of salt-intensive behaviors such as eating out and eating in restaurants positively influences SWB. (3) Perceived high intake of foods high in salt has a nega-tive effect on SWB.
