DIETARY INTERVENTION--EVALUATION OF TECHNOLOGY

Project: Research project

Project Details

Description

This project is designed to evaluate the effectiveness of a video
tape adaptation of the successful weight control intervention used
in the Trial of Antihypertensive Intervention and Management
(TAIM). During the first year of this project we will develop and
pilot test the video tapes and accompanying workbooks. In the
second year we will recruit 150 participants who are above the
NHANES 75th percentile for weight in each of the two adult
communities used in the evaluation. Community A participants
will receive the intervention and Community B participants will
be wait listed and serve as controls the one year before receiving
the intervention. Each community will receive two years of
intervention with Community A having no intervention during the
second year of intervention for Community B.

The weight control program is designed for two years of
intervention and will consist of 10 video tape intervention
sessions, an initial consultation session with a nutritionist, a
telephone hotline for on-going consultation, peer counselling and a
bimonthly newsletter. During the second year of intervention
booster video tape intervention sessions and a structured diet will
be used with participants who fail to achieve a 10 pound or 5% of
body weight loss at the end of one year of intervention.

Weight loss will be used as the primary outcome parameter to
evaluate the effectiveness of the intervention. Cardiovascular
risk status and behavioral measures will be secondary endpoints.
