The 8.4% prevalence of alcohol abuse/dependence estimated by the present study (13.1% for men and 4.1% for women) is above the average value of 6% that Galduroz et al8 (2003) found in a survey performed in 1999.
The rates of alcohol dependence or abuse for the racial/ethnic groups in 2010 were similar to the rates in 2002 and 2009, except that among blacks aged 12 or older, the rate of alcohol dependence or abuse in 2010 (5.7 percent) was lower than that in 2009 (7.0 percent) and in 2002 (7.1 percent).
