Dietary life is closely associated with dietary attitude and diet-related knowledge. Particularly, dietary habit such as sodium intake can be affected by various dietary behaviors such as food choices, dietary attitude toward salty food and a preference for salty taste. The purpose of this study was to assess sodium-related nutrition knowledge and to identify sodium-related attitude and behaviors according to the level of sodium-related knowledge of university students.
Anthropometric measurements were provided by 408 students who participated in this study. The study participants answered questionnaires to provide information on general dietary behaviors, sodium-related dietary attitude and other behavioral factors. A total score of nutrition knowledge was used to categorize study participants in to two groups, namely, low level in sodium-related knowledge (LNaK) or high level in sodium-related knowledge (HNaK) and the attitude and the behaviors of students toward sodium intake were compared between these two groups.
The ratio of female students in HNaK group was higher than that in the LNaK group. HNaK group had a higher score in checking nutrition label of processed food than the LNaK group. Total score of sodium-related attitude and behaviors of HNaK group were 34.81 and 32.75, respectively and these scores were significantly higher than that of the LNaK group whose scores were 32.57 and 30.57, respectively. Total energy intake was not different between two groups but the intakes of calcium, vitamin B2 and folate were higher in HNaK group than in the LNaK group. Correlation analysis adjusted for age and gender revealed that total score of sodium-related nutrition knowledge was positively correlated with total score of sodium-related attitude and behaviors.
In conclusion, students who had high level of sodium-related nutrition knowledge had desirable attitude and behaviors toward sodium intake and these results can be considered in nutrition education for university students.
