Narrator: This is Science Today. Unusually heavy drinking among young white men, which has been a pattern for about three decades, has suddenly dropped within the past 10 years by almost half. Raul Caetano, director of the University of California, Berkeley's Alcohol Research Group, says this drop may reflect a growing trend of health consciousness.
Caetano: There have been many prevention programs, educational and otherwise and it's possible that these programs were more effective among the white population than among the minorities.
Narrator: Caetano says that's because alcohol availability is more pronounced in minority neighborhoods and may be the reason heavy drinking among black and Hispanic men has remained the same.
Caetano: There has been considerable preoccupation in minority communities about the number of liquor stores, the number of outdoor advertising that are in those communities and they are much more prominent than in majority-white middle class communities.
