Objective: To evaluate whether the evidence-based Body & Soul program, when disseminated and implemented without researcher or agency involvement and support, would achieve results similar to those of earlier efficacy and effectiveness trials. Design: Prospective group randomized trial. Setting: Churches with predominantly African American membership. Participants: A total of 1,033 members from the 15 churches completed baseline surveys. Of these participants, 562 (54.4%) completed the follow-up survey 6 months later. Intervention: Church-based nutrition program for African Americans that included pastoral involvement, educational activities, church environmental changes, and peer counseling. Main Outcome Measure: Daily fruit and vegetable (FV) intake was assessed at pre- and posttest. Analysis: Mixed-effects linear models. Results: At posttest, there was no statistically significant difference in daily servings of FVs between the early intervention group participants compared to control group participants (4.7 vs 4.4, P = .38). Process evaluation suggested that added resources such as technical assistance could improve program implementation. Conclusions and Implications: The disseminated program may not produce improvements in FV intake equal to those in the earlier efficacy and effectiveness trials, primarily because of a lack of program implementation. Program dissemination may not achieve public health impact unless support systems are strengthened for adequate implementation at the church level.
