The effects on children and adolescents of parents' excessive drinking: an international review.

The effects during childhood, adolescence, and adulthood of having a parent with a drinking problem has interested researchers in several countries. The greatest number of reports related to this subject have appeared in the U.S. literature and in the literature from countries of Eastern Europe. This review encompasses the findings of researchers in these countries as well as workers in Western Europe, Latin America, and Japan. This review does not include biological, physiological, or neurological data. The epidemiologic evidence from several countries shows significant points of agreement. Problem drinking by a parent markedly increases health risks to children and adolescents. Such risks include diminished intellectual capacity and development, increased neuroticism, and a wide range of psychological and behavioral disorders. Parents who drink excessively are also likely to have children who experience long-term adverse consequences. These include heavy and problem-causing psychoactive substance use, criminality, suicide, depression, personality disorders, and psychological and behavioral disturbances. Parents who drink heavily are also especially likely to produce children who subsequently abstain from alcohol or drink only lightly.
