Alcoholism is a disease in which a person has a physical & psychological need for school
krek1111 [17]

Answer:

The relationship between child abuse and the use or abuse of alcohol has two aspects. First, some findings have indicated that parental alcohol abuse may be associated with the physical or sexual abuse of children. Research findings in this area remain inconsistent, however. Second, the experience of being abused as a child may increase a person’s risk for alcohol-related problems as an adult. This relationship has best been demonstrated in women who had been victims of childhood abuse. Several factors most likely contribute to or influence this relationship, including coping skills; antisocial behavior; and psychological problems, such as posttraumatic stress disorder. KEY WORDS: child abuse; AOD (alcohol or other drug) abuse; risk factors; family AODU (AOD use, abuse, and dependence) history; family dysfunction; marital conflict; sexual abuse; coping; antisocial behavior; posttraumatic stress disorder

According to research estimates, each year more than 1 million children in the United States experience some form of abuse or neglect (Widom 1993). Child abuse is one of the many types of violence associated with alcohol use and abuse, either as a consequence or as a causative factor. For example, parental alcohol abuse may contribute to the abusive treatment of children. Furthermore, people who have been abused as children may be at increased risk for developing alcohol abuse as adults.
