Abstract
BackgroundGestational diabetes is the most common medical complication in pregnancy, and it has many side effects for the mother and the fetus. The aim of this study was to evaluate the effect of oat bran consumption on gestational diabetes.MethodsThis study is a randomized clinical trial that was performed on 112 women with gestational diabetes treated with diet. Participants were randomly divided into two groups of 56. Participants in both groups were given a diet for gestational diabetes. In addition to the diet, the intervention group received 30 g of oat bran daily for 4 weeks at lunch and dinner. Tests of fasting blood glucose and two-hour postprandial (2hpp) glucose were taken from both groups: before the intervention, and 2 and 4 weeks after the start of the intervention. Data analysis was performed using SPSS statistical software (version 22) using independent t-test, as well as Chi-square and Mann-Whitney tests. P values less than 0.05 were considered statistically significant.ResultsThere was no statistically significant difference between the two groups in terms of mean blood glucose before the intervention, while 2 and 4 weeks after the intervention, mean fasting blood glucose and two-hour postprandial (2hpp) glucose decreased significantly in the intervention group compared with the control group (P < 0.001).ConclusionBased on the results of this study, the addition of oat bran to the standard diet for pregnant women with gestational diabetes reduced fasting blood glucose and two-hour postprandial (2hpp) glucose. More detailed studies with higher sample sizes are recommended to prove the effectiveness of this valuable dietary supplement.Trial registrationIRCT registration number:IRCT20191220045828N1.Registration date: 2020-04-18.

In a study by Tapola et al (2005) which aimed to investigate the glycemic response of oat bran products in type 2 diabetic patients, the results showed that oat bran can act as an effective substance to reduce the glycemic response in type 2 diabetics [22]
The present study is a randomized clinical trial that was conducted to investigate the effect of oat bran consumption on gestational diabetes
Summary
Gestational diabetes is the most common medical complication in pregnancy, and it has many side effects for the mother and the fetus. Diabetes is a huge problem for people’s health. This metabolic disease is associated with chronic hyperglycemia, impaired insulin secretion or function, and impaired protein and fat metabolism [1]. One type of diabetes is gestational diabetes that is characterized with glucose intolerance with variable severity which first begins or is diagnosed during pregnancy [2]. 3–5% of pregnancies are complicated by gestational diabetes [3]. The prevalence of gestational diabetes is affected by different diagnostic criteria and varies in different populations from about 3.6% in Northern Europe to 6.3% in Italy [6]. South India has been reported to be 0.6% and in the UK and Northern Europe, the figure is 5.2% [7]
