Objectives: This study examined the relationship between oral health symptoms and Internet usage of Korean adolescents for the purpose of identifying problems associated with Internet usage of adolescents and of preparing measures that can raise awareness on the importance of their oral health management. Methods: The data used in this study is from the 2015 Youth Health Behavior Online Survey (YHBOS). Data from all survey participants (n=68,043) were used in the final analysis, using SPSS Ver. 22.0. General linear models were constructed to analyze the relationship between oral health symptoms and Internet usage of adolescents. Results: In the relationship between Internet usage and oral disease symptoms, those who brush less than once a day during weekdays and weekend tended to use Internet at the highest levels: 72.5%, 78.3% (p<0.001). The following variables were found to be related with spending longer time at Internet: male students (p<0.001), students in lower grades (p<0.001), students with lower performance (p<0.001), and those from families of lower economic level (p<0.001). Moreover, those who brush their teeth less than once a day and those who experienced oral disease symptoms, such as pain during chewing, throbbing and shooting pain, and bad breath in the past year spent longer time at Internet. Conclusions: The above findings show that Internet usage and demographic characteristics of the adolescents are associated with their oral health management. Therefore, guidance and interventions are needed for adolescents with problematic Internet use, while continued education is also needed to raise awareness about the importance of oral health management during adolescence.

For the purpose of developing 'internet nutritional education program', this study analyzed the actual states of internet nutritional information of middle/high school students. Survey questionnaires were distributed from October 21, 2002 to October 26,2002 to a total of 564 students at three junior high schools and five senior high schools located in Seoul. The total number of questionnaires collected and used in our study was 479, which is 84.9% of the total questionnaires distributed. According to the survey results, we found significant difference in the nutritional information source between middle and high school students (p < 0.05) , and two groups responded that effective nutrition information material is 'electronic materials'. Most of the respondents connected with internet more than 1 times per day, but a large number of students were not experienced in using nutrition information of the internet. All groups were using nutrition information of the internet for homework, and satisfaction level of using nutrition information of the internet were an average. Effective methods for acquiring nutrition information of internet were 'educational game' for middle school students and 'bulletin board (Q & A)'for high school students. Moreover the factor analysis for internet nutritional information program's characteristics showed that 'instructing plans','contents of study & technical support','availability'and'interaction'were important considerations for developing internet nutritional information program. We found out through our analysis that was a strong need for a more practical and effective internet nutritional education program for middle and high school students.
