Demographic and socioeconomic disparities of benign cerebral meningiomas in the United States

Abstract:

Epidemiology provides an avenue for deciphering disease pathogenesis. By determining incidence across socioeconomic and demographic variables in the context of benign cerebral meningiomas (BCM), epidemiologic data may aid in elucidating and addressing healthcare inequalities. To investigate BCM incidence (per 100,000) with respect to sex, age, income, residence, and race/ethnicity, we queried the largest United States (US) administrative dataset (1997–2016), the National (Nationwide) Inpatient Sample (NIS), which surveys 20% of US discharges. Annual national BCM incidence was 5.01. Females had an incidence of 6.78, higher (p = 0.0000038) than males at 3.14. Amongst age groups incidence varied (p = 1.65 × 10-11) and was highest amongst those 65–84 (16.71) and 85+ (18.32). Individuals with middle/high income had an incidence of 5.27, higher (p = 0.024) than the 4.91 of low income patients. Depending on whether patients lived in urban, suburban, or rural communities, incidence varied (χ2 = 8.22, p = 0.016) as follows, respectively: 5.23; 4.96; 5.51. Amongst race/ethnicity (p = 8.15 × 10-14), incidence for Whites, Blacks, Asian/Pacific Islanders, Hispanics, and Native Americans were as follows, respectively: 5.05; 4.59; 4.22; 2.99; 0.55. In the US, BCM annual incidence exhibited disparities amongst socioeconomic and demographic subsets. Disproportionately, incidence was greatest for patients who were White, Black, female, 65 and older, and middle/high income.
