[Factors that influence sexual intercourse among middle school students: using data from the 8th (2012) Korea Youth Risk Behavior Web-based Survey].
OBJECTIVE
The purpose of this study was to investigate factors that influence sexual intercourse among middle school students in South Korea.


METHODS
Using statistics from the 8th (2012) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. The study sample comprised 37,297 middle school students aged primarily 12 to 15.


RESULTS
The significant predictors of sexual intercourse were grade, ever smoking, ever drinking, habitual or purposeful drug use, economic status, weekly allowance, cohabitation with family, and type of school.


CONCLUSIONS
The results suggest that intensified sex education is needed not only in the 1st grade of middle school, but also in the upper grades of elementary school. Sexual health interventions for high-risk groups may be needed, given the factors predicting sexual intercourse.
