Street addresses were geocoded and merged with U.S. census data to obtain census tract-level information on income and food access. Choropleth maps visualized IIH clusters within certain neighborhoods. Logistic regression compared the proportion of IIH patients from racial and ethnic minority backgrounds, low-income census tracts, and food deserts and swamps to non-IIH controls.Results: In our cohort, when adjusted for age, women with IIH were more likely to be Black (OR 3.96; 95% CI 2.98-5.25), Hispanic (OR 2.23; 95% CI 1.14-4.36) and live in low-income tracts (OR 2.24; 95 % CI 1.71-2.95) or food swamps (OR 1.54; 95 % CI 1.15-2.07). IIH patients were less likely to live in food deserts than controls (OR 0.61, 95% CI: 0.45-0.83). The association between Black race and IIH remained significant even after adjusting for other variables.Conclusion: IIH is more common among Black and Hispanic women than expected even when accounting for the demographics of a metropolitan city. Some of this relationship is driven by the association of obesity and IIH incidence with low income and proximity to unhealthy foods.
