MMI: mild memory impairment, MMSE: Mini-Mental State Examination, CI: confidence interval.
The number of subjects available for analysis: Control (n = 3696), MMI (n = 121), and Low MMSE score (n = 214).
*The subjects whose GDS score were "6 or more" were excluded from the MMI group.
†Full model included depressive symptoms (only for low MMSE score), age, sex, length of education, frequency of drinking, smoking habit, time spent walking every day, positive history of cancer and diabetes mellitus, and the levels of serum albumin, total cholesterol, and low-density lipoprotein cholesterol.
