This study was an experimental study design with randomized controlled trial.aimed to compare the reduction of HbA1c level among type 2 diabetes mellitus (T2DM) patients between the group given the reciprocal peer support program and the group given regular basis program. We conducted in uncontrolled T2DM patients in the prior six months from April 2019- February 2020, aged of 20-65 years recruited from a Diabetes clinic in Chon Buri. Sixty eligible participants were enrolled to experimental group and control group by using block random methods divided into 30 patients per group. Experimental group be received Reciprocal Peer Support Program and both groups attended the regular basis program then examine levels of HbA1c at the 12 week follow-up. The data analysis were compared between experimental and control groups for homogeneities of demographic data by using independent t-test for continuous variables and z-test for proportion of categorical variables. The main outcome: BMI, BP, FBS, and HbA1c were compared between 2 dependently time (pre- and post- intervention) in each groups by using paired t-test. The mean changes  of HbA1c from baseline to 12 weeks follow-up were compared between group by independent t-test. This research was approved by IRB of Faculty of Medicine, Burapha University, number 015/2019. According to the results of the experimental group had a mean HbA1c of 8.77%  at baseline, which improved to 8.35%  at 12 weeks compared with control group 9.02% to 8.67%. Among patients with a baseline HbA1c >8.0%, the experimental group had a mean HbA1c decrease of 0.98% (p=0.02)  compared with a 0.67% (p>0.05) decrease in control group. There were no differences between groups in mean differences of HbA1c (0.07%, p>0.05). Therefore, people with diabetes may be considered to receive the Reciprocal Peer Support program. Especially in the uncontrollable group If only more than 8% of patients with HbA1c were considered, the program was found to have a statistically significant reduction in HbA1c.
