[Functional and humor disorders as health indicators in adolescence]

In 1988, an epidemiological study concerning self-perceived health problems was carried out on a sample of 3,288 adolescents aged 11 to 19. Eight functional and depressive symptoms (FDS) were investigated. Among girls, FDS (especially sleep disorders, headaches, feelings of nervousness or depression) appeared to be common and increased between ages 11 and 19. Among boys, FDS were less common and did not increase during adolescence. Thus, at age 18, sex differences were clearly established. Results suggest a link between FDS and intrafamilial relationships, especially the aggressive attitude or the rejection of the parents and their lack of interest. For the 11-15 age group, FDS are related to school behavior, but not to school performance.
