Introduction: Diabetes is a major healthcare concern, and physical activity is one of the most important modifiable and preventive factors in individuals with prediabetes.Transtheoretical model (TTM) is identified as a comprehensive approach for physical activity behavior change.Therefore, this study aimed to evaluate the physical activity of patients with prediabetes in based on TTM inSabzevar, Iran.

Methodology: This descriptive and analytical study was conducted on200 individuals with prediabetes, selected through randomized easy sampling.Evaluation was carried out throughthe completion of data collection tools (e.g., demographics questionnaire and constructs ofTTM) by the samples. In addition,reliability and validity of the study tools were confirmed. Data analysis was performed in SPSS version 15.

Results: In total, 70male and 130 female samples with mean age of 48.18±12.23 were evaluated. According to the results, 83% of the samples were in pre-action stages (precontemplation, contemplation, preparation), whereas only 17% of the subjects were in action and maintenance stages. Moreover,a significant difference was observed betweenthe change stages and model’s constructs (P<0.000). It was demonstrated that self-efficacy, processes of change and decisional balance were increased with the progress of samples in the stages of change, from precontemplation to maintenance.

Conclusion: According to the results of this study, most of the participants were in theprecontemplation and contemplation stages. Therefore, it is recommended that propereducational programs be designedregarding the initiation of regular physical activity for specific groups, especially for those in precontemplation and contemplation stages of behavior change.
