Background: Diabetes control in adolescents is a difficult and tedious process. Diabetic teens need
training to control it and prevent its complications. This study aimed to investigate the effect of peer
education on self-care behaviors and glycosylated hemoglobin among adolescents with type 1 diabetes.
Methods: This controlled clinical trial was conducted in Iran from July 2018 to June 2019. 84 teenagers with type 1 diabetes were selected using a simple random sampling and randomly divided into control and intervention groups using block randomization. The intervention group received 4 sessions of training by peers on self care behaviors in diabetes. The control group received the routine training.
The self-care questionnaire was filled out, and glycosylated hemoglobin was measured before and
three months after the intervention. Data were analyzed using SPSS version 23.0. The significance
level was set at P0.05). Besides, the mean glycosylated hemoglobin significantly increased three months after the intervention in the controls (P<0.001).
Conclusion: The implementation of peer education can improve the self-care behaviors and
glycosylated hemoglobin in adolescents. Hence, regarding its low cost and high safety, it is suggested
that this approach should be established in the control of other chronic diseases in order to strengthen the self-care behaviors in adolescents.
