Sodium intake has been associated with the health-related quality of life (HRQoL). This study examined the demographic factors related to HRQoL and whether there is an association between sodium intake and HRQoL in adults residing in rural areas. A total of 1,980 adults (aged ≥20 years) were selected from a cross-sectional study conducted between December 2013 and February 2014 in Gyeongju, South Korea. The sodium intake and HRQoL were measured using a validated food frequency questionnaire and the EuroQol Five-Dimension (EQ-5D) (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), respectively. The education levels (<5 years) were inversely associated with all five dimensions of HRQoL. Men had better EQ-5D scores for each of the five components examined. Adults living with spouses had better scores related to usual activities and anxiety/depression, whereas widowers had decreased scores of mobility and self-care. Unlike older adults aged 70-79 years, adults aged <60 years were more likely to have greater scores related to mobility, usual activities, and pain/discomfort. The income levels were also inversely related to the scores for self-care, usual activities, pain/discomfort, and anxiety/depression. Sodium intake was positively associated with the HRQoL related to self-care, usual activities, and pain/discomfort, but it was negatively associated with anxiety/depression. In conclusion, these findings suggest that the demographic factors and sodium intake were independently associated with HRQoL. The results highlight the need to provide tailored, targeted policies and interventions that consider personal characteristics and dietary intake to improve the overall HRQoL in adults residing in rural areas.
