Better Birth Control Counseling Reduces Unintended Pregnancies Among Young Women

Training health care workers to educate young women about intrauterine devices and contraceptive implants, which are more effective than condoms or the pill, dramatically cut the number of unintended pregnancies among young women seeking family planning services, in a UC San Francisco study done with researchers from Planned Parenthood Federation of America.

The study, published June 17 in The Lancet, was conducted in 40 Planned Parenthood centers around the country. It is the first clinic-based intervention in a randomized trial to reduce unintended pregnancies, which remain stubbornly high in the United States, at about 50 percent.

Since 2009, the American College of Obstetricians and Gynecologists has recommended that IUDs and implants – known as LARC, for long-acting reversible contraceptives – be used as first-line contraceptive methods for most women. Though LARC methods are safe and highly effective for women of all ages, healthcare providers are less familiar with these methods and do not routinely include them in contraceptive counseling.

National surveys show that just 38 percent of U.S. physicians who provide contraceptives offer IUDs to adolescents, 53 percent offer them to women without children and 25 percent offer them immediately after abortion, although it is safe to do so.

“There has been heavy reliance in the United States on the pill and condoms for young people. It’s easy for people to forget to use these methods, which can lead to accidental pregnancies,” said Cynthia Harper, PhD, a professor of Obstetrics, Gynecology & Reproductive Sciences at the UCSF Bixby Center for Global Reproductive Health. “It’s important that women also learn about methods that give a higher level of protection against pregnancy when they seek contraceptive care. Women consider healthcare providers a highly-trusted source of information on birth control, so it’s especially important that providers tell women about all of the methods they can use.”

Researchers tested the training at Planned Parenthood health centers across the country, some of which provided abortion and others only family planning services. They assigned half of the health centers at random to receive the contraceptive training and the other half to continue delivering the care they were already giving.

To be eligible for the study, women had to be between the ages of 18 and 25 and receiving contraceptive counseling because they did not want to become pregnant in the coming year. Ultimately, 1,500 women enrolled.

A key part of the intervention was teaching all health care workers to inform women that different birth control methods have very different levels of effectiveness. For example, less than 1 percent of women using an implant or IUD will get pregnant in the course of a year, while on average 9 percent of women on the pill and 18 percent women whose male partners use condoms will get pregnant in that time.

While 71 percent of the providers who received the training discussed IUDs and implants with their patients, just 39 percent of providers in the control group did. As a result, 28 percent of women in the intervention group chose IUDs or implants, compared with 17 percent in the control group. Women reported a high level of autonomy in choosing their birth control methods, saying they either made the choice on their own or did it together with their providers. 

The training resulted in a striking reduction in the number of unintended pregnancies – from 15 to 8 per 100 women over a year – but only among the women who had come to Planned Parenthood seeking family planning services. For reasons that are not entirely clear, there was no effect among the women who sought birth control after an abortion. Fewer women wanting to use IUDs or implants post-abortion were actually able to get them, and nearly a quarter were pregnant again within a year.

Researchers said restrictions on using public funding for contraception in places that provide abortions may have discouraged many women. IUDs and implants are expensive, costing up to $1,000, and nearly 38 percent of the women in the study had no medical insurance. Over time, however, these methods are cheaper than the pill, since they do not require re-supply.

Copper IUDs have been available in the U.S. since the late 1980s, hormonal IUDs since 2000 and the contraceptive implant since 2006, but American women are still far behind their European counterparts in adopting them. While nearly a quarter of French women use these methods, just 9 percent of U.S. women do, and the Centers for Disease Control and Prevention (CDC) recommends increasing access to them.

“This study shows how important it is that women’s health care providers have full information about available birth control methods and are trained to provide all of these methods to patients at the same visit,” said Carolyn Westhoff, MD, senior medical advisor at Planned Parenthood Federation of America. “It’s one very important part of making sure that women can have the birth control of their choosing — without any barriers.”
