New York, August 6, 2008 Overall alcohol useparticularly consumption of beeris declining in the US, according to a new study published in the August 2008 issue of The American Journal of Medicine. Researchers examined 50 years of data and found several changes in alcohol intake but no change in alcohol use disorders. Americans are drinking significantly less beer and more wine, while hard liquor use has remained fairly constant. More people now report that they are non-drinkers. People born later in the 20th century drink more moderately than older people. As we age, our individual alcohol consumption goes down.
Researchers examined 8,000 records of the Framingham Heart Study, the longest population-based study of American adults ever conducted, to measure alcohol consumption over 50 years. Because the Framingham study recruited subjects that were born before 1900 until 1959, it gives insights into behavior and medical histories through most of the 20th Century. Subjects, both from the original cohort and from the children of the original cohort, have been interviewed every 4 years, from 1948 until 2003. Since each individual was followed directly, a set of histories of lifetime alcohol use could be captured.
While heavy alcohol use is associated with numerous bad outcomes, moderate consumption has been linked to improved cardiovascular health and to improved morbidity and mortality in the elderly. This study shows that, on the whole, the American population is moving in a healthier direction. Despite more favorable patterns of drinking, risk of alcohol dependence did not show a decrease. The proportion of people who developed alcohol-related disorders, such as alcoholic cardiomyopathy or alcoholic cirrhosis remained nearly constant across all age groups.
