Abstract

The purpose of this study was to compare regional differences in salty taste assessments, nutrition knowledge, dietary attitudes and dietary behaviors associated with high-salt diets in four national regions in Korea (Region 1: Seoul, Sokcho, Region 2: Buyeo, Jecheon, Gong Ju, Region 3: Daegu, Gyeongsan, Region 4: Jeon Ju). Subjects were 860 persons who participated in sodium reduction campaign. The result of the salty taste assessment by region was not significantly different. The nutrition knowledge score of subjects in Region 1 was the highest. Dietary attitude scores that showed preference for high-salt diets of Region 2 and Region 4 subjects were higher than those of Regions 1 and 3 subjects (p < 0.001). Dietary behavior scores were not significantly different among regions. The correlation between sodium intake and salty taste assessment was significant (p < 0.01). Older subjects who had high blood pressure levels and lower nutrition knowledge were more likely to have high sodium intakes. Even though the salty taste assessment and dietary behavior scores by region were not significantly different, the salty taste assessment scores had a significant negative correlation with nutrition knowledge and had a significant positive correlation with dietary attitude and dietary behavior in terms of preference for high-salt diets. Therefore, nationwide education regarding salt intake reduction and health and a campaign to encourage favorable attitudes and behavioral changes regarding consumption of a no-salt / low-salt diet is needed.

  Fig. 1. Cervical magnetic resonance imaging (MRI) and right median somatosensory evoked potentials (SEP) of the patient. The T2 weighted MRI with neck in neutral position was unremarkable while T2 weighted MRI with neck in flexion shows anterior displacement of the posterior dural sac (A, B). The reversible inter-peak latency between N13 and N19 on supine (5.5 ms) (C) and flexed (7.45 ms) (D) somatosensory evoked potentials (SEP) in the symptomatic side also support the diagnosis of Hirayama disease. (Normal SEP interpeak latency < 6.59 ms).
