Menstrual-Related Headaches Among a Cohort of African Adolescent Girls.

INTRODUCTION: Migraine attacks associated with menstruation are generally perceived as more severe than attacks outside this period. AIM AND OBJECTIVE: The study aimed at determining the frequency of menstrual-related headaches among a cohort of senior secondary school girls in Abeokuta, Nigeria. We also determined its burden among these school girls. METHODOLOGY: This study was cross-sectional using a validated adolescent headache survey questionnaire. A self-administration of the instrument was done during a school visit. A headache was classified using the ICHD-II criteria. RESULTS: Of the 183 students interviewed, 123(67.2%) had recurrent headaches. Mean age ±SD, 16.18±1.55 (range 12-19). The prevalence of definite migraine was 17.5% while the prevalence of probable migraine was 6.0%. The prevalence of tension-type headache was 41.0%. Migraine was significantly menstrual-related (p=0.001, 95% CI=1.06-6.63). Median pain severity score was higher among MRH group (p=0.043). The median number of days of reduced productivity and missed social activities was significantly higher in the MRH group; p= 0.001 and p=0.03, respectively. Subjects with MRH were more incapacitated by their headaches (p= 0.003). CONCLUSION: Menstrually related headache is prevalent even among the adolescent and it has adversely affected their productivity and social life. Care of adolescent with headaches should be intensified.
