LIÊN QUAN GIỮA MỘT SỐ YẾU TỐ NGUY CƠ, ĐA BỆNH VỚI ĐỘT QUỴ NÃO Ở NGƯỜI BỆNH CAO TUỔI

Abstract

Objective: To evaluate the association between stroke with risk factors, multimorbidity, length of hospital stay, and age groups in elderly patients. Methods: This was a retrospective cross-sectional study conducted at the Department of Senior Officers, Military Hospital 103, from December 2022 to October 2024. The data were collected from 507 medical records of patients aged 60 and above, meeting selection criteria and classified according to International Classification of Disease-10 (ICD-10) codes. Statistical analyses, including chi-square tests, one-way ANOVA, logistic regression, and two-way ANOVA, were used to analyze the data. Results: Stroke patients had significantly higher rates of hypertension (92.8% vs. 55.9%; p<0.001) and diabetes (39.8% vs. 23.8%; p<0.01) compared to non-stroke patients. Hypertension was identified as an independent risk factor for stroke, with an odds ratio (OR) of 0.13 (95% CI: 0.05–0.31, p<0.001). The duration of hospital stay was independently associated with stroke incidence, with an OR of 1.07 (95% CI: 1.02–1.12, p<0.001). The number of comorbidities in the stroke group was also significantly higher (5.42 ± 1.60 vs. 4.22 ± 1.65, p<0.0001). Conclusion: Stroke is closely associated with hypertension, diabetes, and multimorbidity, which contribute to prolonged hospital stays. Hypertension is an independent risk factor for stroke. This study underscores the importance of managing underlying conditions to reduce the risk and burden of stroke.
