The study hypothesis is that individuals with type 2 diabetes (T2D), who adhere to the PANDA intervention, will have improved compliance with the nutritional therapy recommendations of the Canadian Diabetes Association. Specific objectives of this proposal: The objectives of the investigators PANDA (Physical Activity and Nutrition for Diabetes in Alberta) are to (a) to devise and evaluate the efficacy of a multi-level, practical, nutrition intervention program that promotes the individual factors required for effective self-management practices AND that explicitly incorporate strategies to improve food availability, accessibility and acceptability and (b) to use these interventions as a means to examine the relationships between food availability, accessibility, acceptability, adherence to Nutrition Therapy Guidelines, and metabolic indicators of diabetes control in people with type 2 diabetes.

Further study details as provided by University of Alberta:

Primary Outcome Measures:
  • Change in Total Energy Intake [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    Measured using repeated 24 hour dietary recalls (pre and post-intervention)

  • Change in Macronutrient Intake [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    Measured using repeated 24 hour dietary recalls (pre and post-intervention)

  • Change in Nutrient Intake [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    Measured using repeated 24 hour dietary recalls (pre and post-intervention)

Secondary Outcome Measures:
  • Change in Hemoglobin A1c [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    a surrogate of blood glucose control

  • Program Retention [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    attendance at meetings

  • Change in Body Mass Index [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    Actual weight and height used to calculate BMI pre- and post-intervention

  • Body Composition [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    body fat and fat-free mass

  • Change in Blood Biomarkers [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    blood lipids: triglyceride, total cholesterol, LDL-cholesterol, HDL-cholesterol

  • Change in Perceived Dietary Adherence Questionnaire Score [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    Questionnaire assessing self-reported adherence to 9 criteria, whose individual scores (range 0-7) are summed to get the total score. Maximum total score is 63. Minimum total score is 0. A higher score means higher dietary adherence.

  • Food Acceptability [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    questionnaire based on items related to personal and cultural acceptability of the recommended diet

  • Food Accessibility [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    questionnaire of items related to financial and physical accessibility of foods in the diet recommended for diabetes

  • Food Availability [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    questionnaire of items related to the availability in local stores of the food items recommended in the diet for diabetes.

  • Change in Waist Circumference [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    Measured using repeated 24 hour dietary recalls (pre and post-intervention
