Long-acting but reversible methods of birth control becoming increasingly popular

CHICAGO (AP) — Long-acting but reversible methods of birth control are becoming increasingly popular among U.S. women.

A report released today by the Centers for Disease Control and Prevention says birth control pills remain the most popular contraceptive method nationwide, but intrauterine devices and implants are more effective at preventing pregnancy and they last for several years.

National surveys suggest that 7 percent of U.S. reproductive-aged women used long-acting contraceptives in 2011-13. That's up from less than 2 percent in 2002. The most popular are IUDs, T-shaped devices containing hormones or copper that are inserted into the womb. They can work for up to about 10 years.

Implants containing hormones that are inserted beneath the skin last about three years. Both IUDs and implants can cost hundreds of dollars.

The report says long-acting contraceptives were used most by women in their mid-20s and 30s and were more popular with woman who had at least one child.
