The adaptation and translation of the PEACH™ RCT intervention: the process and outcomes of the PEACH™ in the community trial

Objective: To describe the process and report selected outcomes of translating an effective child weight management initiative (PEACH™) from a randomised controlled trial intervention to a community health programme. Study design and methods: Pre-post study design utilising the reach, effectiveness, adoption, implementation and maintenance (RE-AIM) evaluation framework. Adaptation of PEACH™ required significant promotional activity and consideration of legal, ethical and financial issues. PEACH™ components were revised and an evaluation design based on the RE-AIM framework was developed. Facilitator training workshops were made available to South Australian health or education professionals initially, then opened up to new graduates, interstate dietitians and others interested in professional development. Facilitators completed pretraining and post-training questionnaires and a third questionnaire following programme delivery. Data were collected from families by facilitators and returned to university staff for assessment of change (baseline to programme end) in body mass index (BMI) and waist circumference (WC) z-scores. Results: Changes to organisational and political environments prevented maximum programme reach and adoption. Nonetheless, data indicated that PEACH™ was effective at improving facilitators’ confidence (P < 0.05) and children's (n = 37) BMI z-score (−0.17, 95% confidence interval [CI]: 0.03:0.30, P = 0.016), WC z-score (−0.14, 95% CI: −0.02:0.30, P = 0.09) and lifestyle behaviours. Collection of maintenance data was prevented due to time and financial constraints. Conclusions: Translational research needs to develop ways to effectively and efficiently bridge the gap between behavioural research and practice to improve the adoption of evidence-based approaches to child weight management. Nutrition educators and researchers can drive these nutrition-focussed translational research efforts forward. Funding bodies and health service organisations are encouraged to provide financial and structural support for such activity.
