Herbal medicine use and its impact on glycemic control among diabetes patients at governmental hospitals in Debre Berhan, Ethiopia: A cross-sectional study.

BACKGROUND

Diabetes mellitus (DM) is a major health concern worldwide. Diabetes patients are increasingly using herbal medicine (HM) without seeking advice from their healthcare providers. However, its impact on glycemic control is not documented in Ethiopia. Thus, this study aimed to assess herbal medicine use and its effect on glycemic control among diabetes patients at governmental hospitals in Debre Berhan town, Ethiopia.

METHODS

A cross-sectional study involving 430 diabetic patients was conducted at two different hospitals in Debre Berhan town from January 1 to March 30, 2024. Data were gathered using a guided self-administered questionnaire to collect data including glycemic control assessed via hemoglobin A1c (HbA1c) levels. Data was analyzed using SPSS version 25. Logistic regression model was used to assess the predictors of herbal medicine usage, while an independent samples -test was conducted to compare the mean HbA1c levels between herbal medicine users and non-users among diabetes patients.

RESULTS

Of the 430 participants, 72.6 % were diagnosed with type 2 diabetes. The study revealed 48.1 % (95 % CI: 43.3-53) participants used herbal medicine. (33.5 %), (27.4 %), and (17.9 %) were the predominant herbs utilized by diabetic patients. The use of herbal medicine was associated with the patients' diabetic knowledge (AOR: 1.59; 95 % CI: 1.01-2.49), occupation (AOR: 3.7; 95 % CI: 1.36-10.23), income (AOR: 3.58; 95 % CI: 1.22-10.55), and family history of diabetes (AOR: 1.9; 95 % CI: 1.19-3.18). Glycemic status was not controlled for 86 % of herbal users compared to 66.8 % of non-users. Participants who used herbal medicine had significantly higher mean HbA1c by a mean difference of 0.41 (95%CI: 0.04-0.78).

CONCLUSIONS

Herbal medicine use was common among diabetes patients in this study. Poor knowledge about diabetes, a family history of diabetes, lower income, and a farming occupation were identified as strong predictors of HM use. Patients who used herbal medicine had significantly higher mean HbA1c levels compared to non-users. Healthcare providers should engage patients in discussions about herbal medicine use, emphasizing the potential risks to glycemic management. Future research should explore specific herbs used, their mechanisms of action, and strategies to integrate herbal medicine safely into diabetes management protocols.
