Jeong and Jang: Relationship between health risk behaviors, oral health-related behaviors, and experiences of oral symptoms in Korean adolescents: based on 2018 Korea Youth Risk Behavior Web-based Survey



This study investigates the relationship between risky health behaviors, occurrence of oral symptoms, and oral health-related behaviors.


The subjects were 60,040 adolescents selected from the web-based survey from the 2018 Korean Youth Health Behavior of Korean Center for Disease Control. The data were analyzed using a combined sample analysis method. The software SPSS version 12.0 was used to conduct the analyses.


1. Men were observed to partake in risky health behavior at significantly higher rates than were women in terms of smoking, drinking, drugs, and sexual intercourse. Our data showed the percentages of men taking part in these behaviors to be 21.1%, 46.4%, 1.3%, and 7.6%, respectively (P<0.01). 2. Of all subjects, 49.1% brushed their teeth more than three times a day, and 43.6% brushed more than twice a day. Further, a significantly higher number of men (46.0%) did not brush their teeth after lunch compared with women (29.1%) (P<0.01). 3. Of all subjects, 52.9% had developed oral symptoms in the previous year. The rate of women experiencing oral symptoms was significantly higher, at 58.1%, compared with men (48.1%, P<0.01). 4. Risky health behavior, such as smoking, drinking, drugs, and sexual intercourse, was significantly associated with occurrence of oral symptoms (P<0.01). Those that had not partaken in smoking, drinking, and sexual intercourse were significantly lower by 0.73, 0.87, and 0.89 times, respectively, compared with those that responded with “yes” (P<0.01).


We have evaluated the rates of risky health and oral health-related behavior in Korean youth and identify their association with the oral symptoms. It is essential to understand the risks of oral diseases so that appropriate oral health education can be provided to adolescents for promoting behavioral changes.
