The prevalence of type 2 diabetes is increasing among adolescents and clear strategies are needed to prevent it. The aim of this study was to determine the effect of peer education on knowledge, health beliefs and preventive behaviors of type 2 diabetes in female adolescents.
In this cluster randomized trial study, 168 students (84 people in each group) were enrolled. The data collection instrument was a questionnaire of knowledge (30 questions), health beliefs (16 questions) and behavior (20 questions) whose validity and reliability were confirmed. Then eight capable students were chosen as peer educators after being trained. The intervention group received 8 sessions of 90-min education through training, lectures, question and answer, and group discussion and with teaching aids such as pamphlets, educational clips and text messages. The post-test was administered two months after the treatment. Data collected using software SPSS16 and Chi-Square and ANCOVA test were used.
The result showed that the mean and standard deviation of general knowledge, disease symptoms, behavioral risk factors, mid-term outcomes and long-term outcomes, perceived self-efficacy, behavioral beliefs, perceived susceptibility, perceived severity, prevention of stress, healthy food/healthy diet, unhealthy food/unhealthy diet, high-risk behavior, and self-care in the intervention group has increased significantly 2 months after intervention compared of control group (P < 0.001).
Peer education increased knowledge and improved adolescents' health beliefs and behaviors. Therefore, training in adolescence in order to prevention of diabetes can be considered as an effective step, and the use of peer-led education in this field is recommended.

2 型糖尿病在青少年中的患病率正在上升，因此需要明确的策略来预防。本研究旨在确定同伴教育对女性青少年 2 型糖尿病知识、健康信念和预防行为的影响。
在这项整群随机试验研究中，共纳入 168 名学生（每组 84 人）。数据收集工具是一份知识（30 个问题）、健康信念（16 个问题）和行为（20 个问题）问卷，其有效性和可靠性已得到证实。然后，经过培训，选择了 8 名有能力的学生作为同伴教育者。干预组通过培训、讲座、问答和小组讨论以及使用小册子、教育短片和短信等教学辅助工具接受了 8 次 90 分钟的教育。在治疗后两个月进行了后测。使用 SPSS16 软件和卡方检验和协方差分析检验对收集的数据进行了分析。
结果表明，干预组在一般知识、疾病症状、行为危险因素、中期结果和长期结果、自我效能感、行为信念、感知易感性、感知严重性、应激预防、健康食品/健康饮食、不健康食品/不健康饮食、高风险行为和自我护理方面的平均分和标准差在干预后 2 个月显著增加，与对照组相比（P<0.001）。
同伴教育提高了青少年的知识，改善了他们的健康信念和行为。因此，为了预防糖尿病，在青少年中进行培训可以被认为是一个有效的步骤，并且建议在该领域使用同伴主导的教育。
