Kang and Song: Relationship between Snack Intake and Oral Health Behavior of Middle School Students in Gyeonggi Area



The study was performed to investigate the relationship between snack intake and oral health behavior in middle school students in Gyeonggi-do area.


The survey questionnaire was recorded by middle school students from July 6 to August 24, 2011. The questionnaire included items on general characteristics, snack intake status, and oral health behavior. Among collected survey questionnaire, a total of 620 questionnaires (320 males and 300 females) were analyzed using SPSS 15.0 program.


Frequencies of snack and beverage intakes were significantly higher in males than in females (p < 0.001). Oral health behavior was significantly higher in students with lower snack intake compared to those with higher or average snack intake (p < 0.05). Oral health behavior for tooth brushing and toothbrush care were significantly higher in females than in males (p < 0.05).


Oral health behavior score that reflected better oral health of the subjects were higher as the snack intake was lower. Oral health behavior score was higher in females than in males. We conclude that the contents for oral health and nutrition education focused on snack intake need to be developed to induce changes in oral health behavior in middle school students.
