Effect of Lifestyle Promotion in the PRECEDE-PROCEED model among pre-diabetic adults based on PERSIAN cohort study: a randomized controlled trial study

Background Diabetes is a chronic disease caused by impaired glucose metabolism. This study aimed to design and evaluate the effect of a lifestyle promotion program based on the PRECEDE-PROCEED model among pre-diabetic individuals. Methods This randomized controlled trial evaluated the effect of a lifestyle promotion program using the PRECEDE-PROCEED model among pre-diabetic individuals in Hoveizeh city in 2019. The study collected information on the disease status and risk factors associated with non-communicable conditions from the website of Hoveizeh Cohort Study Center. The primary outcome of the study was the percentage of glycated hemoglobin (HbA1c) with a three-month follow-up. Results A total of 240 individuals participated in the study. There was no significant difference in anthropometric characteristics between the intervention and control groups (P < 0.05). Initially, there was no significant difference in the mean HbA1c between the intervention and control groups (P = 0.97). However, after three months of intervention, a statistically significant difference was observed (P > 0.001). The results indicated an increase in the mean quality of life in the intervention group, but no significant difference was found between the two groups or before and after the intervention within each group (P < 0.05). Conclusion The findings suggest that the PRECEDE-PROCEED model provides a suitable framework for training pre-diabetic individuals and patients with type 2 diabetes mellitus (T2DM) to promote self-care behaviors.
