Magnitude of, and Factors Associated with Cardiovascular Disease Among Type Two Diabetes Mellitus Patients

BACKGROUND: Diabetes mellitus is becoming one of the major health problems in developing countries. The number of adults living with type 2 diabetes mellitus (T2DM) worldwide is increasing over time. Cardiovascular disease (CVD) is the major cause of death in T2DM. The objective of this study was to determine the prevalence of cardiovascular disease and its associated factors among diabetic patients at the MRC clinic of Dilla University Referral Hospital (DURH). METHODS: A hospital-based cross-sectional study was conducted from April to May 2019 . A total of 216 diabetic individuals were selected with a convenient sampling technique from patients on follow-up at DURH MRC. Data were collected using a structured format. The diagnosis of CVD was made with the necessary diagnostic tests and examination. The data analysis was done in SPSS software version 20. Bivariate and multivariable logistic regression analysis was carried out to identify factors associated with cardiovascular disease. RESULTS: A total of 216 patients participated in the study and the mean age of the study participants was 30 years; 83.3% of the study participants were male. The overall prevalence of cardiovascular disease was 25% of which 57% were ischemic heart disease, 32% were hypertensive and 10% were stroke. Duration of DM for more than 10 years and diabetic drug discontinuation were factors associated with cardiovascular disease. Odds of CVD was nearly four times more in those whose duration of DM is more than 10 years (AOR=4.00, 95% CI: 2.386–6.705) and odds of CVD among those who discontinued medication were almost three times more, (AOR=2.98, 95% CI: 1.287–6.080). CONCLUSION: A quarter of the diabetic population studied developed CVD. Duration of DM for more than 10 years and drug discontinuation are independent associated factors of CVD. Hence appropriate intervention at early stages should be implemented at primary healthcare level.
