基于健康生态学模型的农村老年人主观认知下降影响因素分析.

Objective To analyze the action path and effect of the influencing factors of subjective cognitive decline of the rural elderly based on the health ecology model, to provide reference for the formulation of intervention measures. Methods By using the methods of multi-stage sampling and convenient sampling, a questionnaire survey was conducted among 595 rural elderly in Zhejiang Province (Ningbo, Shaoxing, Huzhou, and Taizhou). Multiple linear stepwise regression and structural equation model were used to analyze the influencing factors of subjective cognitive decline of rural elderly. Results The total average score of subjective cognition decline questionnaire (SCD-Q21) of 595 rural elderly was (8.41 ±4.84). The results of structural equation model fitting showed that the total effect of individual traits (hearing, distant, proximal, hypertension, decreased grip strength) on the total score of SCD-Q21 was 0.634, the direct effect was 0.311, and the indirect effect was 0.323. The total and direct effects of behavior and psychological factors (drug use, physical activity level, and depression) on the total score of SCD-Q21 were 0.451, and the total and direct effects of life and occupation (education level) on the total score of SCD-Q21 were -0.120. Conclusion The subjective cognitive level of the rural elderly needs to be improved, and relevant intervention measures should be taken according to the influencing factors to improve the cognitive level of the rural elderly.
