The aim of this study was to evaluate the efficacy of self-management education on metabolic control in adults with T2D. Methods: In a quasi-experimental study, 300 patients with T2D recruited from the Diabetes Society of Natanz, Isfahan, Iran, from October 2012 to January 2013. The patients participated in a 16-week educational program held by trained dietician. At baseline, the intervention group attended a 20 minutes lifestyle and nutritional oral education program. Participants were assessed at baseline, 2 and 4 months follow-up for changes in body mass index, glycemic status, and lipid profile. Non-parametric  and  parametric  descriptive  and  group  ×  time  (pre-post)  repeated measure analysis of variance was done. Results: The mean (± standard deviation) amount of weight lost between baseline and the end of 16 weeks was 0.66 ± 1.62 kg in compared to baseline (p < 0.0010). Significant  time  ×  treatment  interaction  effects  were  found  for triglycerides (p < 0.0001), high density lipoprotein-cholesterol (p = 0.0010), fasting blood sugar (FBS) (p < 0.0001), 2-hour postprandial glucose (p < 0.0001), systolic blood pressure (BP)  (p  <  0.0001), diastolic BP  (p < 0.0001), and hemoglobin A1c (HbA1c) (p = 0.0010). Mean FBS concentrations decreased by 30 mg/dl at week16. There was a non-significant increase in the HbA1c. Conclusion: Nutritional/lifestyle counseling may improve metabolic control in T2D patients. Hence, it is possible to improve T2D control by means of non- pharmacologic interventions. https://jnsd.tums.ac.ir/index.php/jnsd/article/view/15 https://jnsd.tums.ac.ir/index.php/jnsd/article/download/15/15
