The cohort
Kroner-Herwig, tension-type headache, pain, headache, migraine
MIGRAINE, TENSION-TYPE HEADACHE, CHRONIC HEADACHES
The cohort included more girls than boys which has also been reported elsewhere for children with recurrent headache [Kroner-Herwig et al. [Most of the children in our study were physically active with less than 10% not participating in sports. However, those not participating in sports may do a lot of active leisure time activities, which are not considered ‘sports’ and therefore not captured by the questionnaire. Interestingly, children in the tension-type headache group were least physically active but had less severe pain than the other two groups. According to the ICHD, tension-type headache is usually not aggravated by physical activity in contrast to migraine, and hence the assumption would be, that children with migraine were the least active, also since they have the highest level of pain. This contradiction could indicate that pain is not the most bothersome issue for children with headache, maybe the quality of the headache has a higher impact on daily life, or maybe physical activity prevents or diminishes tension-type headache.This cohort consists of children with recurrent or chronic headaches. Nevertheless, only half of the children had consulted a general practitioner due to their headache, which was also found in the study by Kroner-Herwig et al. [
