Young women are at a high risk of acquiring STIs (sexually transmitted infections) and of developing the serious complications of untreated chlamydial and gonococcal infections. Almost half of all STIs occur in teenagers and young adults between the ages of 15 and 25. Physical and behavioral factors place the sexually active teenager at an increased risk to develop these infections.
Physically, the cervix is more vulnerable to these infections because it has not fully developed, exposing more susceptible cells to the infections. Since the young woman may be coming into contact with these infectious agents for the first time, her immune defenses are not strong.
Behavioral risk factors include having multiple new sexual partners and not using condoms or not using condoms properly. The U.S. Department of Health and Human Services has a goal to increase the simultaneous use of both condoms and hormonal contraception (birth control pills). This combination of methods is highly effective in preventing a pregnancy and preventing the acquisition of STIs. Yet currently, some studies reveal that only about 5% of adolescent females are using this practice.
