As part of a Finnish national epidemiological study on child psychiatric disorders, psychosomatic symptoms were studied in a sample (n = 1,100) of 8-year-old children on the basis of self-report questionnaires by the children, their parents and teachers. Psychosomatic symptoms were common, although constant symptoms were rare. There were no sex differences in the occurrence of symptoms, but interesting differences were observed in associations between symptoms and other factors. Psychosomatic symptoms were strongly associated with depression scores and school performance.
