Abstract

PURPOSE
This study investigated an association between dietary quality and use of convenience foods at convenience stores among high school students.
METHODS
A total of 474 high school students (225 boys and 249 girls) residing in Incheon participated in this questionnaire survey in June 2018. The subjects were divided into three groups according to the frequency of consumption of convenience foods at convenience stores; less than once a week, 1 ~ 2 times a week, and more than 3 times a week. Dietary quality was assessed using a nutrient quotient for adolescents (NA-Q). Logistic regression was used to investigate an association between dietary quality and use of convenience foods at convenience stores among high school students.
RESULTS
For boys and girls, higher monthly allowance was significantly associated with the higher frequency of consumption of convenience foods at convenience stores, whereas school grade, mother's occupational status, family size, extracurricular study, and eating speed were not significantly associated with the frequency of consumption of convenience foods. Higher intake frequency of cookies or sweet and greasy bread, processed beverage, Ramyon, night-time snack, and street food was significantly associated with the higher frequency of consumption of convenience foods for boys or girls. Boys and girls, who had a higher frequency of consumption of convenience foods at convenience stores had significantly greater odds for being in the low grade of dietary quality, especially in the moderation factor.
CONCLUSION
The students who used convenience stores more often appeared to have more monthly allowance and to consume undesirable foods more often. Higher frequency of using convenience foods at convenience stores among high school students was associated with lower dietary quality. These study results can support efforts to provide nutrition education programs and guidelines to students who frequently use convenience foods at convenience stores.
