Medical Research: What is the background for this study? What are the main findings?
Response: Sexually Transmitted Infections (STIs) are a major public health issue which causes acute illness, infertility, long-term disability or other serious medical and psychological consequences, around the world. Adolescence is a key developmental period with rapid cognitive growth. In recent decades, substantial change in the sexual behaviors and attitudes of adolescents has occurred and this would lead them greater risk of STIs than other. Our study looked at the relationship between adolescents’ first sexual intercourse age and their STI experience, as well as to identify vulnerable time table of their sexual activity by considering the time gap between their secondary sex characteristic occurrence age and first sexual intercourse age.
The findings from our study show that earlier initiation of sexual intercourse increases the odds of experiencing STIs. Also as the age gap gets shorter, the odds of experiencing STIs increase.
Approximately 7.4% of boys and 7.5% of girls reported had STI. For both boys and girls, the chance of experiencing STIs increased as the age of first sexual intercourse decreased [boys: before elementary school (age 7 or under) OR=10.81, first grade (age 7or 8) OR=4.44, second grade (age 8 or 9) OR=8.90, fourth grade (age 10 or 11) OR=7.20, ninth grade (age 15 or 16) OR=2.31; girls: before elementary school OR=18.09, first grade OR=7.26, second grade OR=7.12, fourth grade OR=8.93, ninth grade OR=2.74]. The association between the absolute age gap (AAG: defined as absolute value of “Age gap” = [Age at first sexual intercourse] – [age of secondary sexual manifest]) and STI experience was examined additionally which the result showed, students who had sexual intercourse after their secondary sexual manifestation, as the AAG increases, the odds of STI experience were decreased (boys OR=0.93, girls OR=0.87).
