For level of tea intake: unadjusted model, P for linear trend=0.004; Adjusted model, P for linear trend=0.025; Odds Ratios and 95% confdence intervals were calculated using multiple logistic regression; Variables that were adjusted for in the model are: age, gender, education, smoking, Alcohol consumption, BMI (continuous), Hypertension, Diabetes, Heart disease, Stroke, Depression (GDS ≥5), APOE ɛ4, Physical activities, social and productive activities, vegetables and fruits consumption, fsh consumption, coffee consumption.
