title: [Headache in the population of schoolchildren: prevalence, pattern, risk factors].
abstract: The paper discusses the prevalence, pattern, and risk factors of childhood headache (HA) according to questionnaire data from 1074 general educational school pupils. Periodic HA was reported by 42.1% of the children. There was a preponderance of exercise-induced HA (30.6%) and migraine (7.8%). There was an age and gender determination of childhood HA frequency; there was a predominance of chronic exercise-induced HA, migraine, and their concomitant forms in female adolescents. There was a high comorbidity of primary HA with other psychosomatic disorders mainly with autonomic dysfunction and emotional disorders. The risk factors for chronic HA were a poor family history (familial psychogenias, pain family history, low'socioeconomic status family), and school stress. The clinical form of cephalgia, comorbidities, and predictive factors should be taken into account to prevent and treat HA. The use of the international diagnostic criteria developed by the experts of the HA Association is of cardinal importance in improving the diagnosis of childhood HA.
