Among the 3,246 screened people, there were 172 cases of migraine and 930 cases of headache, yielding a crude 1-year prevalence of 5.3% for migraine (2.3% among men and 7.8% among women) and 28.7% for headache (17.5% among men and 38.2% among women).

Multivariate logistic regression suggested that both migraine and headache were related to the female sex, age, and anxiety and/or depression. This study suggests that migraine is a relatively common disorder in Cuzco, but does not show any difference which could significantly related to altitude. In contrast, our results suggest that headache may be more frequent at high altitude than at sea level.
