Abstract:

Objective: To develop a detailed profile of individuals living with migraine in Canada. Such a profile is important for planning and administration of services. Methods: The 2011–2012 Survey of Living with Neurological Conditions in Canada (SLNCC), a cross-sectional community-based survey, was used to examine a representative sample of migraineurs (N = 949) aged 15 years and older. Several health-related variables were examined (e.g., general health, health utility index (HUI) [a measure of health status and health-related quality of life, where dead = 0.00 and perfect health = 1.00], stigma, depression, and social support). Respondents were further stratified by sex, age, and age of migraine onset. Weighted overall and stratified prevalence estimates and odds ratios, both with 95% CIs, were used to estimate associations. Results: Overall, males had poorer health status compared with females (e.g., mean HUI was 0.67 in males vs. 0.82 in females; men had over two times the odds of their migraine limiting educational and job opportunities compared with females). Poorer health-related variables were seen in the older age groups (35–64 years/≥65 years) compared with the 15–34-year age group. There were no differences between those whose migraine symptoms began before versus after the age of 20 years. Conclusions: In this Canadian sample, migraine was associated with worse health-related variables in men compared with women. However, both men and women were significantly affected by migraine across various health-related variables. Thus, it is important to improve clinical and public health interventions addressing the impact of migraine across individuals of all ages, sexes, and sociodemographic backgrounds.

Vivre avec la migraine au Canada : une étude nationale effectuée en milieu communautaire. Objectif: Élaborer un profil détaillé des individus aux prises avec la migraine au Canada. Un tel profil est important afin de planifier et d’administrer les services offerts. Méthodes: L’Enquête sur les personnes ayant des problèmes neurologiques au Canada (2011–2012), une enquête transversale effectuée en milieu communautaire, a été utilisée pour analyser un échantillon représentatif de patients atteints de migraine (n = 949) et âgés de 15 ans ou plus. Plusieurs variables touchant à la santé ont été examinées (p.ex. : l’état de santé général des patients ; le Health Utility Index [HUI], lequel mesure l’état de santé des individus, leur qualité de vie et en vertu duquel la mort = 0,00 et un état de santé optimal = 1,00 ; la stigmatisation, la présence de symptômes dépressifs et le fait de compter sur un soutien social). Les répondants ont été par la suite stratifiés en fonction de leur sexe, de leur âge et de leur âge au moment où ont débuté leurs symptômes migraineux. On a ensuite utilisé des estimations en matière de prévalence et des rapports des cotes dans le but de mesurer les associations. Tant ces estimations que ces rapports, notons-le, avaient été pondérés de façon générale et stratifiés en fonction d’un intervalle de confiance de 95 %. Résultats: Dans l’ensemble, les hommes ont montré un état de santé davantage précaire si on les compare aux femmes. Ainsi, leur HUI moyen était de 0,67 contre 0,82 chez les femmes. Ajoutons aussi que les hommes étaient deux fois plus susceptibles de voir leurs symptômes migraineux limiter leurs possibilités en matière d’emploi et d’éducation que les femmes. Par ailleurs, de moins bons indicateurs de santé ont été notés au sein des groupes plus âgés (35-64 ans / ≥ 65 ans) en comparaison avec le groupe des 15-34 ans. Aucune différence notable n’a été observée entre les individus dont les symptômes migraineux se sont manifestés avant les 20 ans et ceux chez qui cela s’est passé après 20 ans. Conclusions: Au sein de cet échantillon canadien, on a donc remarqué que la migraine était davantage associée à des indicateurs négatifs de santé chez les hommes que chez les femmes. Cela dit, tant les femmes que les hommes étaient affectés de façon importante par la migraine si l’on tient compte de plusieurs variables touchant à la santé. En cela, il est important d’améliorer les interventions cliniques et de santé publique qui s’intéressent à l’impact de la migraine chez les individus de tout âge, et ce, peu importe leur sexe ou leur profil sociodémographique.
