Depressive symptoms at the age of 12 years and future heavy alcohol use.

Objective: To study the relationships between depressive and psychosomatic symptoms at the age of 12 years and heavy use of alcohol 3 years later, and to determine whether certain depressive symptoms are more predictive than others in regard to later heavy alcohol use.

Methods: The Children's Depression Inventory (CDI) with added questions concerning psychosomatic symptoms and bullying was used to reveal psychiatric symptoms among children at the age of 12 years. Information concerning alcohol use was obtained from the children at the age of 15 years.
