The Migraine in Aotearoa New Zealand Survey (MiANZS) was an online survey run by Migraine Foundation Aotearoa New Zealand in August-October 2022. We had 530 people respond to the survey (see Methodology report for more information about the survey).
All 530 respondents had either a positive score on the ID-Migraine testᵀᴹ and/or a migraine diagnosis from a health professional. The ID-Migraine testᵀᴹ is a set of three questions which helps to identify people with migraine disease. A positive test is when people answer ‘Yes’ to at least two of the three questions.¹ These questions are:
Has a headache limited your activities for a day or more in the last three months? Activities refers to work, study, play or other things you needed to do in the day.
Are you nauseated or sick to your stomach when you have a headache?
Does light bother you when you have a headache?
Of the 530 respondents, 95% reported that headache had limited activities in the last three months, 80% experienced nausea with their headache and 91% reported photophobia (sensitivity to light with a headache).
