Purpose
This study was done to identify contraceptive practices in adolescent girls in South Korea and predictors of contraceptive practices.
Methods
The study sample included 743 girls who had experienced sexual activity. Using statistics from the 12th (2016) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted.
Results
The contraceptive practice rate for adolescent girls was 34%. Contraceptive practice was associated with ‘age at first intercourse’ and ‘sexual intercourse after drinking’. For adolescent girls who had early sexual initiation and drank alcohol before sexual intercourse there was a tendency to reduce the practice of contraception.
Conclusion
It is necessary to provide practical sex education to improve the practice of contraception in these adolescents. In addition, adolescent girls should be encourage to delay their first intercourse. The results of this study can also be used to develop education interventions regarding healthy sexuality behaviour including the practice of contraception.

Purpose
The purpose of this study was to identify the influence of early menarche on sexual experience among high school girls in South Korea.
Methods
The study sample was comprised of 16,286 high school girls. Using statistics from the 11th (2015) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted.
Results
Among the girls, 5.8% reported early menarche. Early menarche was associated with sexual experience (Odds Ratio (OR), 5.27; 95% Confidence Interval (CI), 4.11-6.77). Controlled for sociodemographic, emotional and health behavior characteristics, early menarche was associated with sexual experience (OR, 3.98; 95% CI, 3.04-5.21).
Conclusion
The results indicate that early menarche predicts an increase in sexual experience among female adolescents. Therefore, health education programs and health policy for interventions to improve sexual health are required for girls who are expected to experience early menarche.
