Neighborhood Socioeconomic Disadvantage Increases Risk of Severe Acute Respiratory Syndrome Coronavirus 2-Mediated Otologic Dysfunction

Objectives: We aim to use the Area Deprivation Index (ADI) to investigate the correlations between neighborhood socioeconomic disadvantage (NSD), SARS-CoV-2 vaccination rates, infection severity, and subsequent audiovestibular symptoms.

Methods: In this retrospective cohort study, surveys were administered to participants ≥18 years of age who received a SARS-CoV-2 vaccination and/or tested positive for SARS-CoV-2 infection between January 2020 and September 2022. ADI scores were calculated for each patient to quantify NSD. Statistical analyses were performed to compare demographic and clinical characteristics between ADI quintiles.

Results: Of 2415 participants, the majority were female (62.8%) and White (87%), with a mean age of 60.8 years. Individuals in ADI Quintile 5 were less likely to receive second booster doses than those in Quintile 1 (58% vs. 71%, p < 0.0001). Among those infected with SARS-CoV-2, those in ADI Quintile 5 were 2.5 times more likely to be hospitalized (relative risk = 2.46, 95% confidence interval [1.03, 5.88]) than those in Quintile 1. Symptoms more likely to be experienced by participants in ADI Quintile 5 than those in Quintile 1 immediately following SARS-CoV-2 infection included headaches (28% vs. 21%, p = 0.02), aural fullness (14% vs. 6%, p < 0.0001), change of hearing (8% vs. 4%, p = 0.01), dizziness (15% vs. 8%, p < 0.01), and otalgia (8% vs. 4%, p < 0.01).

Conclusions: Individuals experiencing greater NSD were found to have lower SARS-CoV-2 vaccine booster rates, higher rates of postinfection hospitalization, and increased rates of certain otologic and neurotologic symptoms following infection.
