OR, odds ratio; CI, confidence interval; LDL, low-density lipoprotein; TC, total cholesterol; HDL-C, high-density lipoprotein cholesterol.

Data were obtained from the 2016–2018 Korean National Health and Nutrition Examination Survey. Model 1 was crude. Model 2 was adjusted for age and sex. Model 3 was adjusted for hypertension, diabetes, dyslipidemia, and anemia in addition to the variables included in Model 2. Model 4 was adjusted for current smoking, obesity, noise exposure, stress cognition, and depressive mood or anxiety in addition to the variables included in Model 3 (adjusted R squared for model 1 to 4 were 0.001, 0.007, 0.008, and 0.036, respectively).

^*Serum triglyceride level of ≥200 mg/dL; ^†Defined as a serum LDL level of ≥130 mg/dL; ^‡Defined as above 5.0.
