Application of BASNEF educational model for nutritional education among elderly patients with type 2 diabetes: Improving the glycemic control

Journal of Research in Medical Sciences, 09/16/2011

Sharifirad G et al. - Beliefs, attitudes, subjective norms and enabling factors (BASNEF)–based nutritional educational intervention improved dietary intakes as well as glycemic control, 3 months after intervention.


  • 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.


  • 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.
