Study Finds Longer-Acting Birth Control Options More Reliable
PITTSBURGH (KDKA) -- A new study on birth control finds longer-acting options are much more reliable.
Medical student Kimberly Casten, 26, switched from birth control pills to an IUD because of health concerns.
"I care about the levels of hormones that are circulating in my body because I know it affects my brain," says Casten.
A study in the New England Journal of Medicine finds IUDs, or intrauterine devices, as well as hormonal implants are 20 times more effective at preventing pregnancies than short term contraceptives like birth control pills, the patch or the ring.
"There's a onetime placement and it doesn't require a daily, weekly or monthly administration," says Dr. Adam Jacobs of the Mt. Sinai Medical Center.
There are two kinds of IUDs, both are inserted in the uterus.
The hormonal IUD is approved for five years, and the copper IUD up to 10 years. Hormonal implants, which go in the upper arm, can last for three years.
IUDs and implants have the lowest failure rate, but they're not very popular.
A big reason: many women cannot afford the upfront costs, which can be more than $500.
The study showed that when IUDs were offered for free, 75 percent of women chose them.
Older IUDs were linked to pelvic inflammatory disease, but doctors say current ones are very safe.
"Women clearly are not at increased risk of infection, and are also not at risk of having problems getting pregnant in the future after getting the IUD removed," said Dr. Jacobs.
Casten likes the convenience.
"I don't have to worry about getting my pills every three month," she says. "I really don't have to think about it at all."
She won't have to think about it for another four years.
About three million pregnancies in the United States are unplanned every year. Past studies have shown that about half of these pregnancies are the result of contraception failure.
