Influencing factors of mild cognitive impairment in people with subjective memory complaints / 第二军医大学学报

ABSTRACT

Objective To analyze the influencing factors of mild cognitive impairment (MCI) in the people with subjective memory complaints.Methods Convalescents aged over 60 years old with subjective memory complaints were enrolled in this study. Montreal cognitive assessment scale (MoCA), mini-mental state examination (MMSE) and activity of daily living scale (ADL) were used to screen the participants with MCI, who were allocated into the MCI group. Those without MCI were taken as controls. The sex, age, education backgrounds, chronic disease, physical activity, smoking, drinking and social activity were compared between two groups; and the prevalence rate of MCI and its influencing factors were analyzed. Results The prevalence rate of MCI was 71.15% (37/52) in the MCI group. The proportions of participants aged ≥70 years old, education period ≤12 years, with chronic disease, less physical activity and social activity were significantly higher in MCI group than those in the control group (P0.05). Conclusion Subjective memory complaint is closely related to MCI in the elderly. In those with subjective memory complaint, age, education background, presence of chronic disease, physical activity and social activity are the main influencing factors of MCI.
