Rate of condom use among sexually active adolescents: a nationwide cross-sectional study in Taiwan from 2012 to 2016.

This study highlights an urgent need to instil a proper understanding of protected sex while adolescents are still in their formative years. Despite the low sexual intercourse rate (4.95%), there is lower condom use at last sex than at first sex, which indicates that many sexually active adolescents are not practising protected sex, especially among junior high school students.
