Hammond NG, et al. - In this cross-sectional analysis that used baseline data from the Canadian Longitudinal Study on Aging, researchers investigated the association between social determinants of health, health behaviors, and migraine prevalence. Participants (n_women = 22,176; n_men = 21,549) were aged 45-85 years, and migraine was self-report of physician diagnosis. Men and women had a weighted prevalence of migraine of 7.5% and 19.6%, respectively. Notably, women had a 3% reduced odds of migraine in correlation with a higher perceived social status. Relative to heterosexual men, gay and bisexual men had 50% higher odds of migraine. Women demonstrated a lower likelihood of migraine in correlation with some forms of physical activity. Furthermore, the investigators observed higher odds of migraine among men who engaged in daily walking as a form of leisure-time physical activity.
