Childhood headache at school entry: a controlled clinical study.

Abstract

Our objective was to study the prevalence of different headache types, characterizations, and triggers of headache in Finnish children starting school. Questionnaires were sent to 1,132 families with 6-year-old children. Children with headache disturbing their daily activities (n=96) and an asymptomatic control group of children (n=96) participated in a clinical interview and examination. Children with headache had significantly more bruxism (odds ratio [OR], 1.9; 95% CI, 1.0 to 3.4), tenderness in the occipital muscle insertion areas (OR, 4.8; 95% CI, 1.8 to 12.7), and tenderness in the temporomandibular joint areas (OR, 2.8; 95% CI, 1.3 to 6.0). They also had more travel sickness (OR, 3.4; 95% CI, 1.7 to 6.7) than control children. Eating ice cream (OR, 5.3; 95% CI, 1.4 to 20.3), fear (OR, 3.7; 95% CI, 1.2 to 11.2), and anxiety (OR, 3.2; 95% CI, 1.0 to 10.8) triggered headache more often in migraineurs than in children with tension-type headache. Children with migraine also reported more frequently abdominal (OR, 5.6; 95% CI, 1.7 to 18.1) and other (OR, 3.5; 95% CI, 1.2 to 9.8) pain concurrently with headache, and they used medication for pain relief more often (OR, 3.1; 95% CI, 1.0 to 9.5). Headache classification in children may be improved by palpation of occipital muscle insertions and temporomandibular joint areas, and by discerning a history of triggering events and concurrent symptoms.
