A high prevalence of headache in the studied population was verified. A high headache impact on a student's life was associated with worse academic performance.
- Cross–sectional study.
- 380 students were randomly selected out of the 1718, 90.5% of them were interviewed.
- A semi–structured interview, the Headache Impact Test (HIT–6) and the Hospital Anxiety and Depression Scale were used.
- The variables related to academic performance: absenteeism, performance coefficient and number of failures in disciplines, were obtained by consulting the academic records.
- 344 students were interviewed.
- The headache prevalence was 87.2%. Migraine prevalence was 48.5%.
- Tension–type headache prevalence was 42.4%.
- During the 3 months prior to the interview, 8.7% sought emergency services, 30.8% missed class, and 30.8% had a reduction in their productive capacity because of headache.
- HIT–6: substantial/severe impact = 49%.
- Multiple linear regressions have shown that serious/very serious–impact headaches are significantly related to greater number of discipline failure and absenteeism.
- There was no association between student grades and headaches.
