Predictors of the Timing of Sexual Intercourse Initiation among Adolescents in South Korea
- 9 Downloads
While the age of sexual intercourse initiation has decreased in South Korea, its correlates have not been identified using a nationally representative sample. This study investigated the predictors of the timing of sexual intercourse initiation among high school students in South Korea. A total of 10,810 students in the twelfth grade were selected from the Youth Health Behavior Online Survey (2016), and their data were analyzed using descriptive statistics and survival analysis. Approximately 11.6% of boys and 5.1% of girls reported having sexual intercourse. Significant predictors of the timing of sexual intercourse initiation among male students were the presence of parents, living with their family, socioeconomic status, grade of alcohol consumption initiation, grade of smoking initiation, and school type. Except for school type, the same results were found for girls. Sex education that targets high risk groups using the factors identified in this study may be effective in influencing positive changes in behavioral outcomes, such as delayed initiation of sex.
