Effect of educational intervention based on PRECEDE model on lifestyle modification, self-management behaviors, and hypertension in diabetic patients

Abstract

Background: Inappropriate lifestyle and poor self-management in diabetic patients lead to many complications including hypertension and increased disease burden. Because of insufficient studies on Effect of educational interventions on lifestyle, self-management and hypertension in diabetic patients, the present study aimed to evaluate the Effect of educational intervention based on PRECEDE model on lifestyle, self-management, and hypertension of diabetic patients. Methods: This clinical trial was conducted on 300 diabetic patients with hypertension. The patients were selected using simple random sampling and divided into 2 groups of intervention (150 people) and control (150 people). The intervention group was trained through ten 50–55 min sessions on lifestyle skills, self-management, and hypertension control based on the PRECEDE model. Before and after the intervention, lifestyle skills, self-management, and PRECED model constructs were evaluated using a standard questionnaire. Data were analyzed by SPSS 20 software using t-test, Kolmogorov–Smirnov, and Chi-Square tests (P < 0.05). Results: In the intervention group, the mean score of different dimensions of lifestyle and self-management significantly increased from 110.45 ± 18.78 to 172.58 ± 186.66 and 64.33 ± 15.24 to 144.32 ± 15.82, respectively (P = 0.001). Mean systolic and diastolic blood pressure also decreased from 148.5 ± 5.39 to 123.54 ± 5.32 and 95.41 ± 3.12 to 72.24 ± 3.06 (P < 0.001). Moreover, the mean score of all the PRECEDE model constructs significantly increased after the intervention. In the control group, the mean score of the PRECEDE model constructs, the dimensions of lifestyle, self-management, and systolic and diastolic blood pressure did not change significantly before and after the intervention (P > 0.05). Conclusion: ‌ Based on the study's results, the PRECEDE model was found to be a non-invasive, non-pharmacological, cost-effective method without any complication and as a complementary action along with other methods in the treatment of diabetic patients.
