Abortion is a hotly debated and poorly studied medical procedure. There are a few studies of dubious validity that connect abortion to mental illness and drug use. Politicians have used these studies to justify greater limitations on women seeking abortion in the United States.

There has been no sustained effort to study what happens to women who want abortions but can't get them due to restrictive rules. Until now. These women are called turnaways. A new longitudinal study reveals what happens to their economic position, health, and relationship status after seeking an abortion and being denied it.

Public health researchers with the UC San Francisco group Advancing New Standards in Reproductive Health (ANSIRH) used data from 956 women who sought abortions at 30 different abortion clinics around the U.S. 182 of them were turned away. The researchers, led by Diana Greene Foster, followed and did intensive interviews with these women, who ran the gamut of abortion experiences. Some obtained abortions easily, for some it was a struggle to get them, and some were denied abortions because their pregnancies had lasted a few days beyond the gestational limits of their local clinics. Two weeks ago, the research group presented what they'd learned after two years of the planned five-year, longitudinal "Turnaway Study" at the recent American Public Health Association conference in San Francisco.

Here's the short version of what they discovered, from a post they made on the Global Turnaway Study Facebook page:

We have found that there are no mental health consequences of abortion compared to carrying an unwanted pregnancy to term. There are other interesting findings: even later abortion is safer than childbirth and women who carried an unwanted pregnancy to term are three times more likely than women who receive an abortion to be below the poverty level two years later.
