不同肥胖指标与老年人认知功能的相关性分析

Correlation Analysis of Different Obesity Indicators and Cognitive Function in Older Adults

摘要: 目的：探讨不同肥胖指标与老年人认知功能的关系。方法：本研究利用中国老年健康影响因素跟踪调查项目2018年的追踪调查数据，利用SPSS 27.0进行数据筛查和统计分析。结果：共纳入4438位老人，检出认知功能障碍1547例，检出率为34.86%。二元Logistic回归结果显示，在校正混杂变量后，人体测量指标中WHR、BAI、CI、ABSI是老年人认知功能障碍发生的影响因素(P < 0.05)。高WHR (OR = 1.431, 95% CI 1.085~1.888)、高BAI (OR = 1.479, 95% CI 1.081~2.024)、高ABSI (OR = 2.022, 95% CI 1.114~3.67)是危险因素，高CI (OR = 0.542, 95% CI 0.288~1.02)是老年人认知功能的保护因素。结论：WHR、BAI、CI、ABSI水平与老年人认知功能障碍的发生相关，可以作为预测老年人认知功能障碍的人体测量学指标。

Abstract: Objective: To explore the relationship between different obesity indicators and cognitive function in older adults. Methods: This study utilized the 2018 follow-up survey data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Data screening and statistical analysis were performed using SPSS 27.0. Results: A total of 4,438 older adults were included, among whom 1,547 cases of cognitive impairment were identified, with a detection rate of 34.86%. Binary logistic regression results showed that, after adjusting for confounding variables, WHR, BAI, CI, and ABSI among anthropometric indicators were influencing factors for the occurrence of cognitive impairment in older adults (P < 0.05). High WHR (OR = 1.431, 95% CI 1.085~1.888), high BAI (OR = 1.479, 95% CI 1.081~2.024), and high ABSI (OR = 2.022, 95% CI 1.114~3.670) were risk factors, while high CI (OR = 0.542, 95% CI 0.288~1.020) was a protective factor for cognitive function in older adults. Conclusion: WHR, BAI, CI, and ABSI levels are associated with the occurrence of cognitive impairment in older adults and can serve as anthropometric indicators for predicting cognitive impairment in this population.
