1 Model 1 Model 1 adjusted for age, gender and energy intake. Model 2 further adjusted for intake of fat, smoking, alcohol drinking, income, urbanicity, education, and physical activity. Model 3 further adjusted for overall dietary patterns. Model 4 further adjusted for BMI and hypertension. All the adjusted variables are treated as time-varying covariates (except gender). Model 5 further excluded those who only participated in one wave of the cognitive function tests.
