摘要：Teenager girls represent a particular risk group for unwanted pregnancy and
abortion with important consequences on their health, school and professional
education and social life. In order to avoid this problem appropriate counseling
during contraceptive process is of paramount importance. Apart confi dentiality
the contraceptive counselor must also demonstrate other important qualities like
expertise, trustworthiness and availability. In hormonal contraception adolescents
may be particularly bothered by side eff ects and it is important that they are
counseled about these side eff ects prior to method initiation. Combined hormonal
contraceptive methods with estrogens and progesterone are commonly used among
adolescents, but the failure rate is higher compared to adult women, a possible explanation being lower adherence and higher rates of discontinuation. Depot
medroxyprogesterone acetat (DMPA) is a highly eff ective injectable contraceptive
appealing for adolescents because of its dosing schedule of four times per year.
When using DMPA they should be counseled for changes in menstrual pattern or
amenorrhea and the possible decrease in the bone mineral density if it used longer
than to years. Long-acting, reversible contraception may be particularly suitable
for many adolescents and are considered very eff ective methods. Anyhow with
intrauterine devices (IUDs) the risk of contracting sexually transmitted diseases is
higher and dual protection is mandatory in cases where IUD is used. Adolescents
should be advised on the use of backup contraception and also barrier contraception
for sexually transmitted infections prevention.
