Enhanced Multicenter Dietary Portfolio Study (EDP8)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01954472
Recruitment Status : Withdrawn (This study was combined with another CIHR funded study (NCT02078635). Both studies involve the same dietary portfolio and the same study population.)

Brief Summary:
"Is it possible to recruit and retain up to 200 participants in a Randomize Control Trial (RCT) of high impact lifestyle approach of diet and exercise designed to significantly reduce cardiovascular events in middle-aged and older men and women at high risk of such events?" To address this question, we propose a pilot study of 3 years in duration: 1 year recruitment and randomization, a full year of intervention for all recruited participants, and the last 6 months to assess the one year data and prepare and submit the full trial application, informed by the pilot study outcomes in terms of retention rate. The pilot will then continue on for the full 9 years of intervention and be rolled into the main study involving additional Canadian centers and collaborating international centers in the US, Britain, Europe, Australia, New Zealand, India, and South Africa.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 0 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Investigator)
Primary Purpose: Treatment
Official Title: The Effect of an Enhanced Dietary Portfolio Plus Exercise on Cardiovascular Risk in High Risk Individuals.
Actual Primary Completion Date : October 7, 2014
Actual Study Completion Date : October 7, 2014

Arm Intervention/treatment
Experimental: Enhanced Portfolio plus structured exercise
Diet: The dietary portfolio advice: to limit saturated fat to <7% of total calories and cholesterol to <200 mg/d) plus inclusion of viscous fibres, soy protein, plant sterols and nuts, 5% extra monounsaturated fat, and selection of low glycemic index foods and will emphasize current recommendations for fruit and vegetable intakes (5-10 servings/d).
Behavioral: Enhanced portfolio plus structured exercise

Foods on the dietary portfolio plan will contribute 9g/1000 kcal viscous fibre as β-glucan (oats, barley, oat bran breads and soups) and psyllium (cereal), 1g plant sterol/1000 kcal diet (in sterol margarine), 22.5g soy protein/1000 kcal (soy burgers, dogs, links, other soy meat analogues, soy milks, yogurts and cheese), and additional sources of plant protein from pulses (eg. Lentils, chickpeas, beans, etc) and 22.5g almonds or equivalent of other nuts/1000 kcal and increased MUFA (as olive and canola oils, avocados, nuts, margarine and salad dressings). The glycemic index will be reduced from 83 to 70 GI units (bread scale).

Exercise: The physical activity/exercise program is based on the program used at the Quebec Heart and Lung Institute.

Other Names:
  • Dietary Portfolio of cholesterol-lowering foods
  • Laval exercise program

Active Comparator: High fiber diet plus routine exercise
A diet of whole grain foods (brown rice, whole wheat breads, muffins and breakfast cereals); reduced meat consumption; lower fat dairy foods and a control margarine
Behavioral: High fiber diet plus routine exercise

Dietary advice will be given to encourage intake of whole grain foods (brown rice, whole wheat breads, muffins and breakfast cereals); to reduce meat consumption, choose low fat dairy products and a control margarine.

Exercise: A pamphlet (Canada's Physical Activity Guide, Health Canada) encouraging increased physical activity will be provided.

Primary Outcome Measures :
  1. Feasibility measured by recruitment and retention rates [ Time Frame: 1 year in a 9 year study ]

    Pilot study: Recruitment and retention rates will establish the feasibility of proceeding to the large RCT ie the 9 year intervention study.

    Long term study (9 years intervention): Non-fatal MI, non-fatal stroke and CV mortality as defined by MACE.

Secondary Outcome Measures :
  1. Serum lipids: total cholesterol, LDL-chol, HDL-chol and Triglycerides [ Time Frame: At months -3, -2, -1 and then at months 0, 3, 6 and 12 ]
  2. C-reactive protein [ Time Frame: At months -3, -2, -1 and then at months 0, 3, 6 and 12 ]
  3. Hemoglobin A1c [ Time Frame: At months -3, -2, -1 and then at months 0, 3, 6 and 12 ]
  4. Glucose [ Time Frame: At months -3, -2, -1 and then at months 0, 3, 6 and 12 ]
  5. Blood Pressure [ Time Frame: At months -3, -2, -1 and then at months 0, 3, 6 and 12 ]
  6. treadmill testing [ Time Frame: At months 0 and 12 ]
  7. diet history [ Time Frame: At months -3, -2, -1 and then at months 0, 3, 6 and12 ]
  8. Pedometer records [ Time Frame: At months 0, 2, 4, 6, 8, 10 and 12 ]
  9. Exercise history [ Time Frame: At months 0, 3, 6, and 12 ]
