  1. Model 1: multivariate logistic regression model, adjusted for age, gender and education
  2. Model 2: multivariate logistic regression model, adjusted for age, gender, education, living alone, cigarette smoking, alcohol drinking, anxiety, depression, heart disease, hypertension, diabetes, and Apolipoprotein-ε4
