Social Determinants of Health and Hearing Loss in U.S. Adults

Social determinants of health (SDH) are nonmedical, societal factors that influence health. There is limited information on the current relationship between SDH and hearing loss (HL) in the United States. This study aims to compare the odds of HL among US adults by race/ethnicity, education level, income-to-poverty level ratio, health insurance coverage, and health care access.

Cross-sectional study.

The 2015-2020 National Health and Nutrition Examination Survey data were analyzed to compare odds ratios (ORs) for HL, defined as pure tone average over 25 dB HL in at least one ear, by SDH categories using sample weights. Adjusted ORs were calculated using logistic regression models controlling for sex, age, race/ethnicity, education level, income-to-federal-poverty level, health care insurance coverage and access, and loud noise, pesticide, and cigarette exposure.

A total of 6028 participants were included. Non-Hispanic Black participants had half the odds of HL as Non-Hispanic White participants (OR 0.52, p < 0.05). Lower education level correlated with higher odds of HL: those without a high school diploma had double the odds of HL compared with college graduates or above (OR 2.05, 1.91, p < 0.05). The income-to-federal-poverty level ratio of 1.3 to less than 2 had higher odds of HL than the 4+ group (OR 1.45, p < 0.05). Use of multiple health care locations was associated with nearly three times the odds of HL than the group using one location (OR 2.87, p < 0.05).

SDH are associated with HL. Further investigation is needed into the mechanism of disparities for targeted prevention and treatment for hearing care equity.
