Alcohol, sex and AIDS.

The association between alcohol consumption and AIDS risks is examined. It is concluded that chronic heavy drinking or alcohol consumption levels consistent with alcohol dependence or alcohol-related liver disease does damage the immune system. In addition alcohol consumption influences sexual behaviour for a variety of psychological, social and physical reasons. Attention is focused on the disinhibiting effects of alcohol and the popular belief that drinking may be used to facilitate or excuse otherwise unacceptable behaviour. Several studies indicate that alcohol consumption is associated with 'high risk' sexual behaviour. Accordingly drinking appears to be a risk factor for potential exposure to HIV infection and for relapse into 'high risk' sexual activities. Evidence does not support the conclusion that alcohol is a cofactor in the course of AIDS-related illnesses.
