Underrecognition of migraine-related stigmatizing attitudes and social burden: Results of the OVERCOME Japan study.

Introduction: Migraine-related stigma (MiRS) and social burden is increasingly recognized. We assessed perspectives and attitudes toward migraine in people with and without migraine in Japan.

Methods: OVERCOME (Japan) was a cross-sectional, population-based web survey of people with and without migraine (July-September 2020). People with migraine were individuals who met the modified International Classification of Headache Disorders criteria or had self-reported physician-diagnosed migraine. People without migraine were selected per quota sampling to represent the Japanese adult population. People with migraine reported their experiences on stigma and social burden and answered how frequently they experienced stigma using the MiRS questionnaire. Associations between MiRS and disability and MiRS and interictal burden were examined using the migraine disability assessment and Migraine Interictal Burden Scale-4. People without migraine reported their experiences and attitudes toward people with migraine by answering an 11-item attitudinal migraine questionnaire.

Results: A total of 17,071 and 2008 people with and without migraine, respectively, completed the survey. Overall, 11,228 (65.8%) respondents with migraine reported that they have never experienced stigma or burden; however, of the 12,383 employed respondents, 5841 (47.2%) reported that their current employers are not "extremely" or "very" understanding about their conditions. Moreover, ∼30%-40% of respondents "sometimes," "often," or "very often" hid their migraine from others. The proportion of respondents who experienced stigma often or very often, as assessed by MiRS, was 16.5%; this increased with the increasing number of monthly migraine headache days. The proportion of respondents with moderate-to-severe disability and interictal burden increased with increasing stigma. Among respondents without migraine, the proportion holding a stigmatizing attitude toward those with migraine was low (<15%); ∼80% had never experienced work- or family-related stigma or burden.

Conclusion: MiRS and burden exist but may be hidden and underrecognized in Japan. Disease awareness and education may be important to prevent and reduce stigma and burden.
