UNWANTED PREGNANCIES - UNDERSTANDING CONTRACEPTIVE USE AND BENEFITS IN ADOLESCENTS AND OLDER WOMEN

The highest percentages of unintended pregnancies and the largest increases in births reported in the United States in recent years were in adolescents and in women more than 35 years of age. Increasing numbers of these women will require contraception to avoid unintended pregnancy. In adolescents the combined oral contraceptive agents protect fertility indirectly and exert favorable actions on menstrual dysfunction and certain hormone-related disorders such as acne and hirsutism. To avoid sexually transmitted disease, barrier protection should be used along with oral contraceptives until mutually monogamous, stable relationships are established. Healthy older women who are nonsmokers may also safely use currently available contraceptives. These agents have little impact on metabolic parameters linked to the development of cardiovascular disease. In addition to providing reliable contraception, oral contraceptives offer noncontraceptive benefits to older reproductive-age women, including control of abnormal bleeding and a reduction in the incidence of ovarian and endometrial cancers and other gynecologic pathology. Intrauterine devices and progestin implants are safe, effective, and underused in the United States. Progestin implants may have an additional role in patients for whom estrogen preparations are contraindicated. Counseling is very important before insertion because of the high rate of nuisance side effects. The contraception selection process must consider the efficacy and acceptability of the specific,method to avoid the probability of unintended pregnancy and the risk of sexually transmitted diseases.
