[Point prevalence of psychoactive substance use and depression in childhood and adolescence].

Increasing use of psychoactive substances and early age of initiation to them demand effective methods of prevention and early intervention. In epidemiological studies, 12, 15 and 19 years old students responded anonymously to the question of BDI and Substance Use Questionnaire. The analysis of 3446 sets of questionnaires revealed statistically significant coincidence of depression and use of alcohol and "narcotics" in girls and boys in all studied age groups and of depression and smoking in 12 y.o. boys. The findings allow for indication of depressive children and adolescents as a risk group of substance abuse and dependency development.
