This cross-sectional study aimed to evaluate an association between HL and serum lipid levels.Methods: The study comprised 10,356 Korean adults who participated in the fifth Korea National Health and Nutrition Examination Survey (2010\u20132012). We defined HL as the average hearing thresholds exceeding 25 dB at predetermined frequency levels by pure tone audiometry. Serum lipid levels were measured using an enzymatic assay. The associations between lipid levels and HL were evaluated using a multiple logistic regression model after adjusting for covariates including age, sex, hypertension, diabetes, smoking status, alcohol, physical activity, educational level, household income, and noise exposure. Stratified analyses were performed to examine the effect of the covariates on the association between lipid levels and HL.Results: The high-density lipoprotein cholesterol (HDL-C) level was inversely associated with high-frequency (HF)-HL, with an odds ratio (95% confidence interval) of 0.78 (0.64\u20130.96) for 1-mmol\/L increase in the HDL-C level. Neither the triglyceride nor the low-density lipoprotein cholesterol level was associated with HF-HL. For low-frequency HL, association with any of the serum lipid components was absent. A stratified analysis showed that the inverse association between HDL-C levels and HF-HL was evident (P trend &lt;0.05) in some subjects with specific characteristics such as older age (\u226565 years), female sex, non-hypertensive state, and non-regular physical activity. However, a significant interaction between HDL-C levels and all of the stratified variables was absent (P for interaction &gt;0.05).Conclusion: The HDL-C level has a linear inverse association with the risk of HF-HL. Given the known protective role of HDL-C against atherosclerotic changes, this finding seems to support the concept of impaired microcirculation in the inner ear as a mechanism for HF-HL.<\/jats:p>","DOI":"10.4082\/kjfm.21.0148","type":"journal-article","created":{"date-parts":[[2022,9,20]],"date-time":"2022-09-20T19:24:08Z","timestamp":1663701848000},"page":"334-343","update-policy":"https:\/\/doi.org\/10.4082\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Association
