Background: Individuals with both type 2 diabetes mellitus (T2DM) and hypertension have an increased risk of cognitive impairment (CI) compared to those with either T2DM or hypertension. Therefore, this study aims to identify the prevalence of CI and its associated factors in T2DM patients with hypertension in Hunan, China. Methods: This cross-sectional study included T2DM patients with hypertension admitted to the Department of Endocrinology of Yuanjiang People's Hospital in Hunan Province from July 2022 to February 2023. Data on sociodemographic, lifestyle, disease-related characteristics, and cognitive function were collected through face-to-face interviews. Cognitive function was assessed using the Mini-Mental State Examination. Backward stepwise multivariable logistic regression analysis was used to identify factors associated with CI. The predictive power was examined using the receiver operating characteristic (ROC) curve. Results: A total of 475 participants were included. The prevalence of CI was 38.9% (95% confidence interval [95% CI]: 34.5%-43.3%). Multivariable logistic regression analysis showed that advanced age (odds ratio [OR]=3.21, 95% CI: 1.74-5.93), elementary school or below (OR=3.51, 95% CI: 1.19-10.31), per capita monthly household income ≤2000 RMB (OR=5.29, 95% CI: 2.66-10.51), not current reading books or newspapers (OR=4.48, 95% CI: 1.26-15.99), not current playing cards or mahjong (OR=3.52, 95% CI: 1.91-6.47), current average time of physical activit...
