Abstract
DESCRIPTION (adapted from investigator's abstract): This is a randomized
controlled trial among African Americans (AA) of the effectiveness of a
culturally sensitive self-help nutrition and physical activity intervention,
implemented with and without ongoing counseling for maintenance of target
health behaviors by the method of Motivational Interviewing. Conducted with
the approval and assistance of Atlanta Black churches, the trial is designed
with three experimental conditions: Group 1 (Comparison=C) will receive a
standardized nutrition and exercise intervention (i.e., commercially available
nutrition and exercise videos, audio cassette walking program, and print
materials); Group 2 (Tx1) will receive a culturally sensitive self-help
intervention that includes nutrition and exercise components. The nutrition
component will consist mainly of a the Eat For Life video and cookbook
(developed by the investigators for a related ongoing trial with the input of
the AA community in Atlanta), a video and audiotape set promoting exercise
("Walk With God" to be developed along religious themes and pretested in AA
focus groups in a fashion similar to the Eat for Life), a quarterly newsletter
and other culturally sensitive nutrition and exercise materials. Group 3
(Tx2) will receive the same intervention as Group 2, plus 4 telephone
counseling calls based on Motivational Interviewing. The exercise component
of the intervention will emphasize walking. Churches, rather than
individuals, will be assigned to conditions, and churches will be the unit of
analysis. Fifteen churches will participate in this study and will be matched
in triplets based on denomination, size and income prior to randomization.
To maximize use of personnel and resources and allow for refinement of our
recruitment procedures, the interventions will be implemented in several
partially overlapping cycles over the 2-year intervention phase. A total of
950 subjects will participate in the study (approx. 60/church). All
participants will be recruited at health fairs conducted in participating
churches. The goals of the interventions and primary outcomes for the study
are: a) to increase fruit and vegetable consumption by serving-a-day in
Group Tx1 vs C and in Tx2 vs Tx1; b) increase physical activity by 20 minutes
per week in Group Tx1 vs C and in Tx2 vs Tx1. Dietary outcomes will be
assessed with food frequency questionnaires plus 24-hour recalls in a 50
percent subsample. Physical activity will be assessed with a seven-day recall
as well as cardiovascular fitness (cycle ergometer) in a 20 percent subsample.
Recruitment and retention of participants will be maximized by several
strategies including incentives for each church, and the use of church
liaisons to assist in participant recruitment and tracking.
