Program Implementation and Church Members' Health Behaviors in a Countywide Study of the Faith, Activity, and Nutrition Program.

Implementation research of health programs in faith-based organizations is lacking. The Faith, Activity, and Nutrition (FAN) program helps churches improve physical activity and fruit and vegetable behaviors of members. This study examined associations between implementation of FAN intervention components and church members' physical activity, fruit and vegetable behaviors, and self-efficacy for improving these behaviors. FAN was implemented in 35 churches in a southeastern US county. After attending in-person training, led by community health advisors, church committees received 12 months of telephone-delivered technical assistance to implement FAN according to 4 components: increasing opportunities, increasing guidelines and policies, increasing pastor support, and increasing messages for physical activity and healthy eating in their church. In this correlational study, FAN coordinators (n = 35) for each church reported baseline practices in 2015 and 12-month follow-up implementation of the 4 components for physical activity and healthy eating in 2016. Church members (n = 893) reported perceived implementation, physical activity and fruit and vegetable behaviors, and self-efficacy at 12-month follow-up in 2016. Independent variables were coordinator-reported baseline practices, baseline-adjusted 12-month implementation, and member-perceived 12-month implementation. Multilevel modeling examined associations between independent variables and member-reported 12-month physical activity and fruit and vegetable behaviors and self-efficacy. Coordinator-reported 12-month implementation of fruit and vegetable opportunities was associated with member fruit and vegetable consumption. Member perceptions at 12 months of church physical activity opportunities, pastor support, and messages were associated with higher self-efficacy for physical activity; pastor support and messages were positively associated with physical activity. Member perceptions at 12 months of fruit and vegetable opportunities, pastor support, and messages were associated with higher fruit and vegetable consumption and self-efficacy. Member-perceived implementation was more strongly associated with member behaviors than coordinator-reported implementation. Providing opportunities for healthy eating during already scheduled events may be an effective strategy for improving fruit and vegetable behavior.
