  1. Crude model: No other covariates were adjusted
  2. Model I: adjusted for age, sex, race, body mass index, sleep duration, smoking, and drinking
  3. Model II: adjusted for Model I plus high-density lipoprotein cholesterol, triglycerides, and low-density lipoprotein cholesterol
  4. OR Odds ratio, CI Confidence interval; Rarely, the frequency of snoring, gasping or stopping breathing while sleeping during the past year was 1 to 2 nights per week; Occasionally, the frequency of snoring, gasping or stopping breathing while sleeping during the past year was 3 to 4 nights per week; Frequently, the frequency of snoring, gasping or stopping breathing while sleeping during the past year was 5 or more nights per week
