Epidemiology of migraine among students from randomly selected secondary schools in Lodz

The purpose of the present study was to determine the prevalence of migraine among 2351 secondary school students aged 15 to 19 years. Six hundred fifty-nine students (120 males and 539 females) complained of migraine, including 148 with additional tension-type headache (mixed headache). Migraine with aura was diagnosed in 213 students (49 with mixed headache). The remaining 446 students (99 with mixed headache) had migraine without aura. In 83 students (16 with mixed headache), headaches were developing into migrainous states. In 237 students (56 with mixed headache), headaches were accompanied by dizziness. In 128 females (25 with mixed headache), interrelation between migraine and menstruation was found. Familial factors affecting the occurrence of migraine were noted in 536 students (127 with mixed headache). It was found that 28% of secondary school students aged 15 to 19 years suffer from migraine. Nine percent of them have migraine with aura and 19%, migraine without aura. The prevalence of migraine among secondary school students is about three times higher in females than in males. Migraine with tension-type headache differs from pure migraine in respect of more numerous attacks within 1 year among females, and of more frequent occurrence of migraine with sensory aura among males.
