[Children and bodily pain. Strong association between bodily pain, mental problems and sleep disorders among school children].

Body pain is frequently reported in children, and it has been suggested that childhood pain could be the beginning of chronic disabling pain. Three hypotheses were tested: 1. Body pain is associated with mental distress and sleeping problems; 2. The association is dependent on the localisation of the pain; 3. The association increases with the number of painful areas. 86 percent of the pupils (569) in the 4th form (mean age 10.5 years), 7th form (mean age 13.5 years) and 9th form (mean age 15.5 years) from all the schools in a local community answered a questionnaire about self esteem, body image, physical activity and body pain. A strong association was found between the reporting of pain, mental distress and sleeping problems. Knee pain was the only problem reported more frequently by boys than by girls, and did not show the same association with mental distress and sleeping problems as pain from other regions.
