This study will train Lay Health Promoters (LHPs) from African-American churches to
administer healthy living lessons and activities to their congregations in order to improve
overall health and address cardiovascular disease. The primary hypothesis is that LHP
training combined with a well supported maintenance strategy will be more effective than LHP
training alone in reducing risk factors for cardiovascular disease.
The GoodNEWS Trial is an 18-month effectiveness trial with an 18-month extended maintenance
study, among 20 African-American and low-income congregations participating in the GoodNEWS
faith-based lay health promotion program. After training, congregations will be randomized
to either GoodNEWS with a health maintenance intervention (GoodNEWS-I) or GoodNEWS program
alone (GoodNEWS-PA). The maintenance intervention combines elements of the medical care
model and features of community-based support. Primary data collection will occur at
baseline, 18, and 36 months with the two primary outcomes being levels of physical activity
as measured by 7- Day Physical Activity Recall (PAR) and dietary change as measured by the
Diet History Questionnaire (DHQ). The primary hypothesis is that the maintenance group will
significantly increase physical activity and healthy eating behavior compared to the program
only group. We also hypothesize that lipoprotein and glucose levels, and blood pressure
will be significantly improved over baseline in the GoodNEWS-I group and that these changes
will be significantly greater than in the GoodNEWS-PA group. At the end of the trial, both
groups will continue in an 18-month extended maintenance study.
