May 3, 2012ATLANTA (AP) -- Health officials say more teen girls use the best kinds of birth control.
A recent survey found 60 percent of teen girls who have sex use the most effective kinds of contraception. That's up from the mid-90s, when less than half were using the best.
Health officials say the trend may help explain a large decline in the U.S. teen birth rate since 1990.
The most effective forms of birth control were the pill, patch, vaginal ring, IUD, arm implant and contraceptive shot. Using only condoms was deemed only moderately effective.
The Centers for Disease Control and Prevention released the report Thursday. It's based on a survey of 2,300 girls ages 15 to 19.
