Increasing Treatment for Obesity Among Underserved Populations

Summary

The objective of this project is to evaluate strategies to increase patient engagement in evidence-based interventions (EBIs) for obesity. The scientific premise of the proposed project is based on: 1) substantial evidence that EBIs for obesity are effective but grossly underutilized, 2) promising results indicating that technology-based approaches such as text messaging may increase the reach of EBIs among underserved populations, 3) data demonstrating that repeated offers of treatment can substantially increase enrollment even among patients who are initially unmotivated, and 4) prior research highlighting the effectiveness of Motivation And Problem Solving (MAPS), a proactive coaching approach used to address barriers to improve patient enrollment in EBIs.

Thus, the proposed project will develop, implement, and evaluate two strategies for increasing the assessment and enrollment of University of Utah Medicaid patients in online EBIs for obesity: 1) Repeated offers of EBIs for obesity using text messaging and state of the science health communication strategies, 2) MAPS navigation/counseling among patients who do not enroll in EBIs in response to text messaging. The proposed project will provide critical data regarding the implementation of pragmatic and scalable interventions that are designed to increase the reach of existing EBIs for obesity among underserved populations. Most importantly, the project results lay the foundation for the widespread dissemination of strategies to increase use of EBIs for obesity across Utah, the Mountain West region, and the nation.

Project deliverables include 1) a text messaging intervention for facilitating connection to EBIs for obesity; 2) MAPS intervention for facilitating connection to EBIs for obesity; 3) implementation, adaptation, and optimization of these interventions for University of Utah Medicaid patients, 4) preliminary evidence for the efficacy of these two interventions in improving the reach of EBIs for obesity, and 5) creation of a plan for further dissemination.
