  1. Model 1 was unadjusted
  2. Model 2 was adjusted for sex, age, race, education, marital status, PIR, and BMI
  3. Model 3 was further adjusted for smoking status, drinking status, physical activity, hypertension, hyperlipidemia, and DM, based on model2
  4. Results are presented as ORs and 95% CIs.
