title: Disease and pregnancy in adolescent girls.
abstract: The frequency of visits to the outpatient clinic, chief complaints, and pregnancies of adolescent girls were analyzed. The age distribution of adolescent girls who visited the clinic showed that the higher the age, the higher the frequency of menstrual cycle abnormalities. Recently, increased sexual activity has been seen in teenagers and has caused problems, especially the increase in teenage pregnancies, contributing to increases in induced abortion. To avoid unwanted pregnancy of unmarried teenagers, intensive sex education is essential, as well as provision of contraceptives.
