Nutrition intervention strategies in the Multiple Risk Factor Intervention Trial (MRFIT)

The Multiple Risk Factor Intervention Trial (MRFIT) simultaneously intervenes on three major risk factors for coronary heart disease: Hypercholesteremia, hypertension, and cigarette smoking. It was, therefore, essential to develop intervention strategies which would be appropriate across all modalities. The initial methodology combines the transfer of basic information, the use of small groups of participants and their homemakers to facilitate changes in life style, and the use of the principles of behavioral change and maintenance theory to encourage long-term success in adapting and maintaining new habits over a life time.
