Improving Uutritional Behaviors of Pre-Diabetic Patients in Yazd City: a Theory-Based Intervention

Understanding relationships between dietary factors and prevention of diabetes is increasing. Pre-diabetic patients should have an appropriate diet. The overall goal of this project was to investigate the effect of application of Trans-theoretical Model based education on enhancing nutritional behaviors in pre-diabetic individuals in Yazd city. This experimental-trial research with control group was conducted on randomized samples of 220 pre-diabetic patients referred to Yazd city health centers using Trans-theoretical Model to improve nutritional behaviors controlling diabetes. In order to achieve project goals، a multi-dimensional questionnaire was designed based on the model constructs and requirements and filled in a long with 72-hour recall and food frequency forms by participants before and after intervention. Before intervention، measurements of stage of change construct revealed that majority of participants (i. e. 86. 4% of experimental group and 79. 1% of control group) were in the pre-action stages (pre-contemplation، contemplation and preparation) in terms of nutritional behaviors. However، 21. 4% of the experimental group and 73. 4% of the control group were observed in the pre-action stages after the intervention. Type 2 diabetes is a global crisis that threatens health and economy of all nations. Scientific evidence shows that the vast majority of type 2 diabetes can be prevented through improving diet and lifestyle modification in pre-diabetic patients.
