Now, Bars in Alaska have started offering pregnancy tests with an aim to reduce the number of babies born with fetal alcohol syndrome in the state. Alaska has one of the highest rates in the country.

Supporters are hopeful that the tests will reach women early in pregnancy, which is the crucial time as they might not know they're expecting.

At the Peanut Farm bar in Anchorage, there is a dispenser, hanging on the wall inside the ladies room, advertising free pregnancy tests. All you need to do is press the button for getting one of the self-administered urine tests.

In the front of the machine a poster is featured showing a silhouette of a pregnant woman drinking from a bottle is. The text at the top said 'Remember the last time you had sex'?

Aimee Rathbone said that at first she didn't notice the dispenser, so she doesn't know if it would catch her eye to make her take a test before she drank or not.

Rathbone wondered who's the target audience as she believed that most women will quit drinking after they find out they're pregnant.

She said, "I think anybody that might suspect it wouldn't drink except if they were addicted. You know, if they had a drinking problem then maybe it wouldn't really change things".

State health officials estimated that over 120 children born in Alaska each year showed fetal alcohol symptoms, ranging from mental and physical disabilities to impaired growth to organ damage.

According to the Centers for Disease Control and Prevention, Alaska also has a high rate of women who binge drink.

The University of Alaska is going to conduct the two-year study. Researcher David Driscoll said that it will look at whether pregnancy test dispensers in bar bathrooms can become more effective at preventing fetal alcohol syndrome than posters by themselves.

So far, the tests are in only four bars across the state, but Driscoll is planning to add more soon.
