Association between migraine and anxiety symptoms: Results from the study of women's health across the nation.

BACKGROUND

This study aimed to examine the relationship between migraine and anxiety in US midlife women.

METHODS

This study was conducted on the baseline data from the Study of Women's Health Across the Nation (SWAN), a multi-site longitudinal population-based study of the US midlife women. Logistic regression was performed to assess the odds ratios (ORs) and 95% confidence intervals (CIs) between migraine and anxiety, adjusting for the main potential confounders.

RESULTS

A total of 3,302 midlife women aged from 42 to 52 with complete assessment of migraine and anxiety were enrolled. In both the crude model (OR: 1.47, 95% CI: 1.19-1.82, p < 0.001) and model 1 (OR: 1.31, 95% CI: 1.04-1.64, p = 0.022) indicated that anxiety was positive associated with migraine. After adjustment for age, ethnicity, family income, body mass index (BMI), smoking, alcohol drinking, physical activity, hypertension, diabetes, hypercholesterolemia, menopausal status, estradiol, dehydroepiandrosterone sulfate, follicle-stimulating hormone, sex hormone-binding globulin, testosterone, and thyroid stimulating hormone in full adjusted model 2, the association between migraine and anxiety remained statistically significant (OR: 1.28, 95% CI: 1.01-1.61, p = 0.038).

CONCLUSION

Migraine may be positively associated with anxiety in middle-aged women. Further large-scale prospective cohort studies are needed to investigate the causality between migraine and anxiety.
