Headache in college students: a comparison of four populations.

Recent studies have reported a much lower rate of headache prevalence for Australian college students as compared with those for two campuses in the United States. We present such data here for a third U.S. campus and make several comparisons of these data for the four campuses. While the gender difference of higher female over male headache frequency was found for all four campuses, the same measure for combined genders is reliably higher for all three U.S. groups over their Australian counterpart and there are significant differences among the U.S. groups as well. Possible reasons for these campus differences in headache prevalence are outlined and discussed and further research is indicated.
