Assessment of Knowledge on Cardiovascular Disease Risk Factors Among Diabetes Mellitus Patients in Tikur Anbessa Specialized Hospital, Ethiopia 2021: A Cross-Sectional Study

Introduction: Cardiovascular diseases (CVDs) are a growing problem with increasing global prevalence and the most common cause of mortality worldwide. Knowledge about the disease and risk factors reduces exposure to modifiable risk factors and, as a result, contributes to prevention. As diabetes is a prevalent disease and there is limited research about CVD risk factors in Ethiopia, we conducted a study to assess this knowledge.Methods: A cross-sectional study was conducted on diabetes mellitus patients on follow-up at Tikur Anbessa Specialized Hospital from April 11 to May 16, 2021. The participants were selected using a consecutive sampling method. Knowledge was measured using a heart disease fact questionnaire, and a score of less than 70% was defined as suboptimal. Data were analyzed using SPSS Version 26.0. Associations between dependent and independent variables were identified based on AOR, with 95% CI and a p value less than or equal to 0.05.Result: A total of 404 patients with a mean age of 52.03 ± 14.39 participated in the study, and more than half, 217 (53.7%), of patients were females. About half of the patients (52%) had good knowledge of CVD risk factors. In multivariable logistic regression, urban residency (AOR, 3.335; 95% CI [1.134–9.809]), higher educational level (AOR, 4.016; 95% CI [1.78–9.061]), being employed (AOR, 1.942; 95% CI [1.058–3.566]), and hearing information about CVD risk factors (AOR, 2.492; 95% CI [1.573–3.949]) are associated with knowledge of CVD risk factors.Conclusion: This study revealed that almost half of diabetes mellitus patients had suboptimal knowledge about CVD risk factors. Urban residence, higher education level, employment, and information about CVD risk factors are positively associated with good knowledge of CVD risk factors. Health education is needed to improve their knowledge.
