The Relationship between Problematic Internet Use and Health Risk Behavior in Community High School Students

Objectives: Studies investigating problematic internet use have increased rapidly and have been focused on its causes, psychopathology, prevalence, characteristics and so on. However, there are few studies concerning the correlation between problematic internet use and youth health risk behavior. Therefore, the purpose of this study was to examine the relationship between problematic internet use and youth health risk behavior. Methods: A community sample of 632 high school students in grades 10 and 11 was collected for the survey. The sample was assessed using the Youth Risk Behavior Surveillance System(YRBSS) and Young's Diagnostic Questionnaire of Internet Addiction(YDQ). The subjects were classified into two groups: normal and problematic internet use, and the problematic internet use group was further divided into at-risk use and addiction groups. Results: There were 56 subjects(8.9%) in the internet addiction group and 56 subjects(8.9%) in the at-risk internet use group. The other 507 subjects were classified as normal. The subjects in the internet addiction group kissed more frequently and ate less fruit than those in the normal group. They also showed a relatively higher tendency to watch TV, ride in a car driven by a drunk driver and to carry a weapon than those in the normal group. There were no differences in health risk behaviors between the subjects in the internet addiction group and those in the at-risk internet use group, except for the possibility of riding in a car driven by a drunk driver. Conclusion: Unlike the normal group, there was very little difference in health risk behavior between the internet addiction group and the at-risk internet use group, which indicates that the addiction group and the at-risk internet use groups are homogenous. It is important to focus on the behavior of individuals in the at-risk group, and preventive measures should be taken in order to reduce the possibility of at-risk adolescents becoming addicted.
