Hematological Parameters Among Adult Patients Diagnosed With Type 2 Diabetes Mellitus at Jimma University Medical Center, Jimma, Southwest, Ethiopia

<b>Background:</b> Diabetes is a significant worldwide health challenge associated with significant metabolic, cellular, and hematological disturbances. Hematological alterations are well-documented complications of diabetes and play a crucial role in the progression of diabetes related pathology. While extensive data exist globally on hematological parameters in type 2 diabetes mellitus (T2DM), specific insights into these parameters and their local determinants within study area remain limited. Therefore, this study aimed to assess the hematological parameters among adult patients diagnosed with T2DM in JUMC at Jimma, Southwest, Ethiopia, 2024. <b>Methods:</b> A total of 200 medical charts of adults with T2DM who registered for follow-up at Jimma University Medical Center were reviewed from December 2023 to February 2024. Data were collected using a data extraction checklist. Bivariate and multivariate logistic regression analyses were performed to identify factors associated with hematologic abnormalities. A <i>p</i> value less than 0.05 indicates statistical significance. <b>Result:</b> The overall prevalence of anemia and leukocytosis in adults with T2DM was 14.0% and 12.0%, respectively. Neutrophilia was the common white blood cell (WBC) abnormality detected in 9.5% of the patients. Besides, thrombocytopenia and thrombocytosis were observed in 2.5% and 1.5% of the patients, respectively. Increasing age 5.28 (95% CI: 1.07-26.1) and duration of diabetes mellitus (≥ 3 years) (AOD = 3.1 (95% CI: 1.02-9.5)) were significantly associated with anemia and leukocytosis, respectively. <b>Conclusion:</b> This study found a prevalence of hematological abnormalities in adults with T2DM, including anemia, elevated WBC count, increased neutrophils, and thrombocytopenia. Anemia was associated with advanced age, while leukocytosis was associated with a longer diabetes duration. Therefore, it is recommended to start regularly screening T2DM patients for hematological abnormalities to improve clinical practice, guide treatment decisions, and develop targeted interventions.
