  • BACKGROUND: The objective of this study was to determine the effects of nutritional educational program on glycemic control of elderly patients with type 2 diabetes.
  • METHODS: In this parallel randomized controlled educational trial, 100 diabetic elderly patients (≥60 years) were chosen (50 in control and 50 in test group). Nutrition education based on beliefs, attitudes, subjective norms and enabling factors (BASNEF model) was conducted. Dietary intake and glycemic indices as well as the components of the BASNEF model were assessed. The four 70-minute educational sessions were conducted in one month. Three months after training intervention, questionnaire was completed again and blood tests were performed.
  • RESULTS: Increased intake in the mean daily servings of fruits (0.91 ± 0.82 vs. 0.17 ± 0.79; p < 0.001), vegetables (0.87 ± 0.86 vs. 0.03 ± 1; p < 0.001) and dairy (0.35 ± 0.52 vs. and 0.12 ± 0.76; p < 0.001) were reported in the intervention group compared to the control group (p < 0.001). The amount of fruits, vegetables and dairy increased in the intervention group at the end of the study (p < 0.001). However, it was not significantly changed in the control group. HbA1c and fasting blood sugar (FBS) levels decreased significantly in the interventional group compared to the control group (p < 0.001). Comparing the amount of FBS and HbA1c at the end of the study with the baseline measurements showed significant reduction in interventional group (p < 0.001). However, there was no significant change in control group in this regard.
  • CONCLUSIONS: BASNEF–based nutritional educational intervention improved dietary intakes as well as glycemic control, 3 months after intervention.
