Abstract

Subjective cognitive decline (SCD) is more prevalent in the elderly Chinese population, and individuals with hypertension are at greater risk for cognitive impairment. The aim of this study was to investigate the prevalence and factors affecting SCD in elderly hypertensive patients and to develop a risk prediction model. This was a cross-sectional study of 1098 elderly hypertensive patients in a tertiary care hospital. The prevalence of SCD in elderly hypertensive patients was 45.2 %. Education level, exercise, disease duration, blood pressure grade, depression, nutrition, debility, and sleep disorders were influential factors. A prediction model was constructed using these factors. The internal validation AUROC is 0.877 and the external validation AUROC is 0.813. Calibration curves and DCA curves indicated that the prediction model was well fitted. The predictive model constructed in this study may be useful for clinical screening and the development of targeted intervention programs.

老年高血压患者主观认知能力下降的影响因素分析及风险预测模型的构建。

主观认知能力下降（SCD）在中国老年人群中更为普遍，而高血压患者发生认知障碍的风险更大。本研究旨在调查老年高血压患者 SCD 的患病率和影响因素，并建立一个风险预测模型。这是一项横断面研究，对象是一家三级医院的 1098 名老年高血压患者。老年高血压患者的 SCD 患病率为 45.2%。教育水平、运动、病程、血压等级、抑郁、营养、衰弱和睡眠障碍是影响因素。利用这些因素构建了一个预测模型。内部验证 AUROC 为 0.877，外部验证 AUROC 为 0.813。校准曲线和 DCA 曲线表明预测模型拟合良好。本研究构建的预测模型可用于临床筛查和制定有针对性的干预计划。
