Longitudinal course of vasomotor symptoms in perimenopausal migraineurs

摘要

Objective To examine the longitudinal course of vasomotor symptoms (VMS) in women with a history of migraine in comparison to women without a history of migraine disease. Methods The study sample consisted of 467 women with a self-reported prior migraine diagnosis and 2,466 women without prior migraine diagnosis who were assessed longitudinally during menopausal transition as part of the Study of Women's Health Across the Nation. Linear mixed regression models with backward elimination were used to evaluate longitudinal associations between VMS and migraine while adjusting for baseline and time-varying demographic, socioeconomic, psychological, and reproductive factors. Additional analyses were performed to further assess the specificity of the association between migraine and VMS that included evaluating the association between migraine and vaginal dryness and between back pain and VMS. Results A history of migraine predicted an increased frequency of VMS but not vaginal dryness during menopausal transition. Significant interaction between history of migraine and menopausal status for the prediction of VMS was also identified. Burden of VMS was found to be higher during late-stage perimenopause in women with migraine. In contrast, the history of back pain did not predict the frequency of VMS. Interpretation This is the first study to delineate that a history of migraine predicts an increased frequency of VMS in women during menopausal transition. Hypothalamic abnormalities and thermoregulatory dysfunction against a milieu of decreasing estradiol concentrations during menopausal transition may explain the increased frequency of VMS in migraineurs during menopausal transition.
