Eighty-two percent of teen pregnancies are unplanned; teens account for about 1/5 of all unintended pregnancies annually and 10% of all U.S. births are to teenagers. Fifty-nine percent of pregnancies among 15–19-year-olds in 2006 ended in birth, 27% in abortion and 14% in miscarriage. Black and Hispanic women have the highest teen pregnancy rates; their rates are more than double the rates of non-Hispanic whites.
Sexual Activity and Use of Contraception
The condom is the most common contraceptive method used at first intercourse; 68% of females and 80% of males use it the first time they have sex. In 2006–2010, some 96% of sexually experienced female teens had used a condom at least once, 57% had used withdrawal and 56% had used the pill. Smaller proportions had used other methods.
Almost the entire decline in teen pregnancy rates in the United States is the result of improved contraceptive use; the remaining share is from increased proportions of teens choosing to delay sexual activity. In 2006–2010, some 86% of female teens and 93% of male teens reported using contraceptives at last sex. These proportions represent a marked improvement since 1995.
The Consequences of Teen Sex and Pregnancy
As a recent Guttmacher Institute report noted: “Unintended pregnancy can force women and their families to confront difficult abortion decisions or the potentially negative consequences associated with unplanned childbearing—including child health and development issues, relationship instability, and compromises in education and employment that may exacerbate ongoing poverty.”
U.S. women aged 15-19 had more than 200,000 abortions in 2006. The reasons teens most frequently give for having an abortion are that they are concerned about how having a baby would change their lives, they cannot afford a baby now and do not feel mature enough to raise a child.
Babies born to teens are more likely to be low birth-weight than are those born to women in their 20s and 30s. Teen childbearing is associated with reduced educational attainment. Teen mothers are substantially less likely than women who delay childbearing to complete high school or obtain a GED by age 22 (66% vs. 94%). And of important consequence to future careers and earning potential, fewer than 2% of teens who have a baby before age 18 attain a college degree by age 30.
Although ages 15-24 years represent only 1/4 of the sexually active population, they account for nearly half (9.1 million) of the 18.9 million new cases of STIs each year. Young people aged 13-24 made up about 17% of all people diagnosed with HIV/AIDS in the United States in 2008. The CDC reports that although blacks represent approximately 14% of the US population, they acquired an estimated 44% of new HIV infections in 2009 with the greatest incidence among men who have sex with men. In 2009, the rate of new HIV infections among black men was 6 1/2 times higher than that of white men, and the estimated rate of new HIV infections among black women was 15 times that of white women and more than three times that of Latina women. The CDC estimates that the lifetime risk of being diagnosed with HIV is approximately 1 in 16 for black men and 1 in 32 for black women.
Following many years of experience and research, a clear picture of the effectiveness of abstinence-only education has emerged. As described by a Guttmacher Institute report, “A recent, congressionally mandated evaluation of federally funded abstinence-only programs by Mathematica Policy Research—conducted over 9 years at a cost of almost $8 million—found that these programs have no beneficial impact on young people’s sexual behavior .” Furthermore, to the extent that they ignore contraception and the benefits of safer-sex practices generally, abstinence-only programs do nothing to help prepare young people for when they will become sexually active.
In contrast, based on hundreds of program evaluations, there is strong evidence that comprehensive sex education can effectively delay sex among young people, even as it increases condom and overall contraceptive use among sexually active youth. Surveys among adults, parents, teachers
Access to Contraceptive Services
In 2002, some 90% of publicly funded family planning clinics counseled clients younger than 18 about abstinence, the importance of communicating with parents about sex or both topics. Nearly 2 million women younger than 20 were served by publicly supported family planning centers in 2005; these teens represented 1/4 of the centers’ contraceptive clients. In 2006, only 5% of American high schools made condoms available to students.
Access to Abortion
To facilitate these views, schools in England and Wales, France and Sweden and in most of Canada provide age appropriate sexuality education at many grade levels that include explicit and comprehensive information about contraception and STI prevention.
These same countries provide contraceptive services that are integrated into other types of primary care and are available free or at low cost for all teenagers. Generally, teens know where to obtain confidential information and services and receive nonjudgmental care.
These same principles have worked well when implemented in the U.S. such as in the state of California. In 1992, California’s teen pregnancy rate was the highest in the nation: For every 1,000 women aged 15–19 in the state, 157 became pregnant that year. By 2005, the rate had essentially been cut in half—to an all-time low of 75 per 1,000. California’s teen pregnancy rate decline was the steepest for any state, and it was far above the national decline of 37% over the same period.
Public health experts in California credit teen pregnancy prevention efforts dating back to the 1990s for the state’s record declines. California—the only state that never accepted federal abstinence-only dollars—has made teen pregnancy prevention a high public policy priority, with a strong emphasis on providing teens with comprehensive sex education and on fostering their access to the information and health care services they need to prevent pregnancy and protect their health. This concerted statewide effort is still ongoing with 94% of schools providing HIV/AIDS prevention education and 96% providing sex education.
Since 1997, through a Medicaid waiver known as the Family Planning, Access, Care, and Treatment (Family PACT) program, California provides a package of contraceptive and related reproductive health services at no cost to 1.4 million adolescents and adults, males and females with incomes up to 200% of the federal poverty level. Roughly 20% of Family PACT clients are younger than 20 and Latinos account for 52% of Family PACT’s teen clients.
Another lesson of the studies of reproductive health programs for adolescents is that the ability to choose among the most effective contraceptives is important. Although hormonal methods, pills, rings, injectables and the patch are theoretically highly effective, under typical use conditions they frequently fail. Among teenagers, oral contraceptives, condoms, injectables and withdrawal are the most commonly used methods . While with perfect use these methods are highly effective, 9% of pill users, 18% of condom users, 6% of injectable users and a high proportion of withdrawal users will become pregnant during the first year of typical use .
Contraceptive effectiveness of these methods is also substantially impaired because of high discontinuation rates. About half of condom and injectable contraception users—and almost 1/3 of pill users—will discontinue use within a year and may become non-users of contraception . Long-acting reversible contraceptive (LARC) methods, such as intrauterine contraceptives and implants, have a proven record of very high effectiveness, many years of effectiveness, convenience, cost effectiveness, and suitability for a wide variety of women, including teens who have not had children. However these methods comprise only 5.5% of contraceptive use in the U.S. Programs that emphasize use of the LARC methods could decrease the current unacceptably high rate of unintended pregnancies among teens.
