Background: Dyslipidemia is one of the major modifiable risk factors for cardiovascular diseases (CVD)rnin a type-2 diabetic (T2DM) patient. Dyslipidemia in T2DM patients is attributed to increased free fattyrnacid flux secondary to insulin resistance. Globally burden of dyslipidemia in diabetic patients isrncontinuously increasing. Intensive management of dyslipidemia and its associated factors is required tornprevent cardiovascular disease. rnObjective: The study was designed to assess the prevalence and associated factors of dyslipidemia amongrnadult patients with type 2 diabetes at Tikur Anbessa Specialized Hospital (TASH), Addis Ababa, Ethiopia. rnMethod: An institution-based- cross-sectional study was conducted from July 10 to November 10, 2021.rnA convenience sampling technique was used to recruit 208 T2DM patients. Data on socio-demographicrncharacteristics, behavioral, and clinical factors were collected using a structured questionnaire throughrnface to face interview. Anthropometry and blood pressure were measured. Laboratory data were retrievedrnfrom patients chart. Data was entered and analyzed using SPSS version 25. To identify determinantrnfactors of dyslipidemia, bivariate and multivariate binary logistic regression analyses were done.rnStatistical significance was considered at the level of significance of 5%, and adjusted odds ratio (AOR)rnwith 95% confidence interval (CI) was used to present the estimates of the strength of the association. rnResults: The overall prevalence of dyslipidemia among study participants was 78.4%.rnHypertriglyceridemia was found in 42.8%, hypercholesterolemia in 25.1%, high low-density lipoprotein inrn30.3%, and low high-density lipoprotein in 36.5% study participants. Longer duration of diabetesrn&physical inactivity were significantly associated with dyslipidemia. Patients who have more than 10rnyears duration of diabetes had five times (95% CI, 1.24-20.149) more risk of dyslipidemia as comparedrnwith less than 5 years duration. Type2 DM patients who donâ€™t perform moderate physical activity hadrnnearly three times (95% CI, 1.077-7.767) increased risk of dyslipidemia as compared with those whornperform 5-7 days moderate physical activity in a week. rnConclusion: A high prevalence of dyslipidemia was found among T2DM patients in the study area. rnPhysical inactivity and longer duration of diabetes were significantly associated with dyslipidemia amongrnT2DM patients. Clinicians need to screen, treat, and educate diabetic patients about dyslipidemia and itsrnassociated risk factors.
