Comparison of salty taste assessment, high-salt dietary attitude and high-salt dietary behavior by stage of behavior change among students in Daegu / 한국영양학회지

ABSTRACT

PURPOSE: This study was conducted for comparison of salty taste assessment, salty taste preference, high-salt dietary attitude, and high-salt dietary behavior by stages of behavior change among school-aged children and adolescents. METHODS: A total of 1,595 students (1,126 school- aged children, 469 adolescents) from 43 elementary schools and 17 middle and high schools in Daegu were tested using salty taste kits and surveyed using questionnaires on stages of behavior change, high-salt dietary attitude, and behavior. RESULTS: Adolescents showed a significantly higher result for salty taste assessment than school-aged children (p < 0.01). In salty taste assessment, the students of pre-contemplation stage (n = 498) and contemplation stage (n = 686) showed higher scores than students of action stage (n = 351) and maintenance stage (n = 60). Regarding the salty taste preference, students of maintenance stage preferred the lower two samples (0.08%, 0.16%) and students of pre-contemplation stage preferred the higher two samples (0.63%, 1.25%). High-salt dietary attitude scores and dietary behavior scores were highest for students of pre-contemplation stage and were lowest for students of maintenance stage. CONCLUSION: Salty taste assessment, high-salt dietary attitude, and high-salt dietary behavior were significantly different by stages of behavior change among school-aged children and adolescents. This study suggests the need for examination of the stages of behavior change before nutrition education for effective education.
