medications acamprosate or disulfiram may also be used to help prevent further drinking. Mental illness or other addictions may complicate treatment. Various forms of individual or group therapy or support groups are used to attempt to keep a person from returning to alcoholism. One support group is Alcoholics Anonymous. The World Health Organization has estimated that , there were 380 million people with alcoholism worldwide (5.1% of the population over 15 years of age). in the United States, about 17 million (7%) of adults and 0.7 million (2.8%) of those age 12 to 17 years of age are affected. Alcoholism is most common among males and young adults. Geographically, it is least common in Africa (1.1% of the population) and has the highest rates in Eastern Europe (11%). Alcoholism directly resulted in 139,000 deaths in 2013, up from 112,000 deaths in 1990. A total of 3.3 million deaths (5.9% of all deaths) are believed to be due to alcohol. Alcoholism reduces a person's life expectancy by approximately ten years. Many terms, some slurs and others informal, have been used to refer to people affected by alcoholism; the expressions include tippler, drunkard, dipsomaniac and souse. In 1979, the World Health Organization discouraged the use of alcoholism due to its inexact meaning, preferring alcohol dependence syndrome.
