This article aims to estimate the prevalence of cognitive impairment and analyze its association with blood pressure control in elderly hypertensive individuals. Cross-sectional study of 383 elderly hypertensive individuals in the state of Piauí, Brazil. The authors collected sociodemographic and clinical data, performed blood pressure measurement, and assessed cognitive function using the Montreal Cognitive Assessment (MoCA) test. Poisson regression with robust variance was used. Overall prevalence of cognitive impairment was 74.4%, higher in the age group 80 years and over and among older persons with less schooling. Prevalence of uncontrolled blood pressure was 61.6%, with a higher proportion in the elderly with cognitive impairment. An association was observed between cognitive impairment and uncontrolled blood pressure (aPR: 3.98; 95%CI = 2.51-6.33). The significant association between cognitive function and blood pressure control suggest that cognitive impairment is an important risk factor for uncontrolled blood pressure in older persons. The inclusion of screening measures for possible cognitive deficits may be useful for better monitoring blood pressure levels among elderly hypertensive individuals.
本文旨在评估认知障碍的患病率，并分析其与老年高血压患者血压控制的关系。这是一项对巴西皮奥伊州 383 名老年高血压患者进行的横断面研究。作者收集了社会人口学和临床数据，进行了血压测量，并使用蒙特利尔认知评估（MoCA）测试评估了认知功能。采用了稳健方差的泊松回归。认知障碍的总体患病率为 74.4%，在 80 岁及以上年龄组和受教育程度较低的老年人中更高。血压控制不佳的患病率为 61.6%，认知障碍患者中比例更高。认知障碍与血压控制不佳之间存在关联（调整后的患病率比：3.98；95%CI = 2.51-6.33）。认知功能与血压控制之间的显著关联表明，认知障碍是老年人血压控制不佳的一个重要危险因素。对可能存在的认知缺陷进行筛查可能有助于更好地监测老年高血压患者的血压水平。
