To investigate the association between Healthy Eating Index 2015 scores and hearing loss.
This study used cross-sectional data from individuals aged over 20 years (n = 5171) who participated in the National Health and Nutrition Examination Survey from 1999 to 2012 and from 2015 to 2018. Information was collected on their hearing, Healthy Eating Index 2015 scores, and several other important covariates using multivariate regression analyses.
After adjusting for potential confounders, when hearing loss was defined as ≥20 dB, the odds ratios for low-frequency and high-frequency hearing loss were 0.99 (95 per cent confidence interval (CI) = 0.98−0.99, p < 0.001) and 0.99 (95 per cent CI = 0.98−1, p = 0.006), respectively. When hearing loss was defined as >25 dB, the odds ratios for low-frequency hearing loss and speech-frequency band hearing loss were 0.98 (95 per cent CI = 0.98−0.99, p < 0.001) and 0.99 (95 per cent CI = 0.98−1, p = 0.008), respectively.
In U.S. adults, the Healthy Eating Index 2015 is associated with hearing loss.
