[Prospective study on dynamics of depression in late adolescence].

Aim: To assess changes in occurrence of depressive disorders during late adolescence a prospective epidemiological study was carried out.
Method: Representative sample of 17 y.o. school adolescents (N=2094) was screened for depression with the Krakow Depression Inventory (KID) in 2001, 2002 and 2003.
Results: Point prevalence of depression was found respectively: 27.27% for 17 y.o., 27.43% for 18 y.o., and 26.69% for 19 y.o. and was relatively stable in the sample studied.
Conclusions: It was found that depression is more often in late-adolescent girls than in boys of the same age. The dynamics of depression across the years suggests a differentiated nature of the disturbance.
