Abstract
Background: Several comprehensive studies and evidences support the role of fiber in glycemic
control. The glucose-lowering effect of fiber intake has not been consistently demonstrated in the
literature and the effect related with source and amount of fiber intake of Type 2 DM patients.
Although poor glycemic control has become more prevalent in Ethiopia in recent years, such
information however is contextually limited in Ethiopia. Thus, this study attempted to examine
the sources and quantify amount of dietary fiber intake and its effect on glycemic control of Type
2 DM patients.
Objective: To determine the sources and amount of dietary fiber intake and its effect on
glycemic control among Type 2 DM patients on follow up general government hospitals of
Addis Ababa, Ethiopia ,2024
Methods: A facility-based cross-sectional study was conducted among 282 Type 2 DM patients
selected from Zewedtu Memorial Hospital, Yekatit 12 hospital and medical college, Tirunesh
Bejing hospital and Ras desta Dametew hospital from March, 2024 to April, 2024. Data was
collected from study participants using KOBO collect mobile data collection app. Repeated
multiple pass 24-hour recall was used to collect dietary data. Dietary data was collected using
portion size estimation methods and analyzed in to nutrient using Nutrisurvey2007.The final data
analyzed using the Statistical Product and Service Solutions (SPSS) version 27.The association
between dietary fiber and glycemic control was assessed with Pearson correlation and declared
strong if Pearson coefficient was above 0.7.
Result :The most predominant source of dietary fiber intake was cereal (79.5%). The mean (SD)
dietary fiber intake and HgA1C were 32.5 ± 20 g/d and 7.61 ±1.49 respectively. Dietary fiber
has an inverse correlation with HgA1c, with a Pearson correlation of -0.383 (p value <0.001). Of
all measures of glycemic control total energy, duration of DM followup and dietary fiber were
positive significant association with poor glycemic control with a P value<0.05. .
Conclusion : Dietary fiber intake of respondents were inline with the recommendation.
Incorporating fiber rich food in a diet improves glycemic management of Type 2DM patients
.Therefore, consumption diet rich in fiber for Type 2 DM patients is recommended.
