SURVEY ON CHARACTERISTICS AND RELATED FACTORS OF COGNITIVE IMPAIRMENT IN ELDERLY PATIENTS WITH HYPERTENSION
Main Article Content
Abstract
Background: According to the World Health Organization (WHO) in 2021, the prevalence of cognitive impairment in people aged 60 and above is approximately 5-8% globally, and it doubles every 5 years. In the age group above 85, this rate can reach about 20-30%. Particularly in elderly patients with hypertension, cognitive impairment needs to be given more attention. Objective: To describe characteristics and analyze factors related to cognitive impairment in elderly patients with hypertension. Materials and methods: Elderly patients aged 60 and above diagnosed with hypertension and undergoing treatment at the Geriatric Department, Can Tho Central General Hospital from April 2020 to February 2022, using a cross-sectional descriptive study design with analysis. Cognitive assessment using Mini-Cog scale: Impaired cognition (<4 points) and Nonimpaired cognition (≥4 points). Results: Among the 180 elderly participants in the study, 23.3% had cognitive impairment according to the Mini-Cog scale. There was a statistically significant association between cognitive impairment and gender, social activity, and comorbidities in a univariate model. Individuals with more than two comorbidities had a higher rate of cognitive disorders, with an adjusted odds ratio (95% CI) of 2.97 (1.36-6.37) after adjusting for other factors in the multivariate model. Conclusions: The prevalence of cognitive impairment in elderly patients with hypertension is 23.3%. Univariate and multivariate regression analyses revealed that there were more than 2 comorbidities significantly associated with the likelihood of cognitive impairment in elderly patients with hypertension.
