Trying to find someone to join you in a drink? It may be harder than it used to be.

Americans are drinking less, according to a report in the August issue of the American Journal of Medicine.

Mostly, they're drinking less beer, as the consumption of wine goes up and hard liquor stays about the same.

Researchers found that people born later in the 20th century tend to drink more moderately than those that came before and that alcohol consumption drops as people age.

For example, researchers looked at how much people born in 20 year spans drank when they were between 30 and 59 years old. Those born earliest, from 1900 to 1919, drank an average of 30.6 grams of alcohol a day. Those born from 1920 to 1939 drank 25.5 grams a day, and Baby Boomers born between 1940 and 1959 drank 21 grams a day.

And more people now say they are non-drinkers, according to a news release.

The information came from examining the Framingham Heart Study, which has followed 8,000 people, some for more than 50 years.

While heavy alcohol use is associated with many problems, moderate consumption has been linked to improved cardiovascular health and a lower death risk, according to a news release on the study.

However, researchers also said that the risk of alcoholism and other problems such as cirrhosis were consistent among age groups.
