Proposed Medicare Coverage for Diabetes Prevention: Strengths, Limitations, and Recommendations for Improvement

A Multilevel Diabetes and CVD Risk Reduction Intervention in African American Churches: Project Faith Influencing Transformation (FIT) Feasibility and Outcomes

Wide-reaching health promotion interventions are needed in influential, accessible community settings to address African American (AA) diabetes and CVD disparities. Most AAs are overweight/obese, which is a primary clinical risk factor for diabetes/CVD. Using a faith-community-engaged approach, this study examined feasibility and outcomes of Project Faith Influencing Transformation (FIT), a diabetes/CVD screening, prevention, and linkage to care pilot intervention to increase weight loss in AA church-populations at 8 months. Six churches were matched and randomized to multilevel FIT intervention or standard education control arms. Key multilevel religiously tailored FIT intervention components included: (a) individual self-help materials (e.g., risk checklists, pledge cards); (b) YMCA-facilitated weekly group Diabetes Prevention Program (DPP) weight loss classes; (c) church service activities (e.g., sermons, responsive readings); and (d) church-community text/voice messages to promote healthy eating and physical activity. Health screenings (e.g., weight, blood pressure, blood glucose) were held during church services to identify participants with diabetes/CVD risks and refer them to their church's DPP class and linkage to care services. Participants (N = 352 church members and community members using churches' outreach ministries) were primarily female (67%) and overweight/obese (87%). Overall, FIT intervention participants were significantly more likely to achieve a > 5 lb weight loss (OR = 1.6; CI = 1.24, 2.01) than controls. Odds of intervention FIT-DPP participants achieving a > 5 lb weight loss were 3.6 times more than controls (p < .07). Exposure to sermons, text/email messages, brochures, commitment cards, and posters was significantly related to > 5 lb. weight loss. AA churches can feasibly assist in increasing reach and impact of diabetes/CVD risk reduction interventions with intensive weight loss components among at risk AA church-populations.

Current Perspectives on the Impact of the National Diabetes Prevention Program: Building on Successes and Overcoming Challenges

To address the public health and economic burden of type 2 diabetes, the Centers for Disease Control and Prevention (CDC) began dissemination of the National Diabetes Prevention Program (NDPP) in the United States in 2010. Based on the intensive lifestyle intervention from a large efficacy trial, the NDPP aims to reduce incidence through lifestyle change and weight loss. This narrative review summarizes evidence on reach, effectiveness, and sustainability of the NDPP, while highlighting opportunities to overcome challenges in these areas. Major successes include reaching hundreds of thousands of at-risk individuals across the nation, with notable effectiveness upon full participation and widespread insurance coverage. Yet, more work is needed to ensure greater public health impact, particularly among priority populations at heightened risk who also experience disparities in program outcomes. Preliminary evidence suggests a number of strategies may improve reach and effectiveness of the NDPP, often with more rigorous study needed prior to widespread uptake. Updating the NDPP to better match the current evidence-base may also be important, such as directly targeting glycemia with a patient-centered approach and promoting metformin as an adjunct or second-line treatment. Finally, revisiting pay-for-performance reimbursement models may be critical to sustainability by ensuring adequate availability of suppliers and ultimately reducing diabetes prevalence.

Behavior Modification in Prediabetes and Diabetes: Potential Use of Real-Time Continuous Glucose Monitoring

Real-time continuous glucose monitoring (RT-CGM) provides real time glucose readings to participants wearing the device. The ability to see changes in glucose has the potential to provide immediate feedback to users on food choices and physical activity. The National Diabetes Prevention Program is currently the only reimbursable intervention for diabetes prevention and weight loss. The purpose of this article is to review the CGM literature on measurements other than Hemoglobin A1c (HbA1c) changes and hypoglycemia and discuss RT-CGM potential use as a behavior modification tool for lifestyle changes and weight reduction in people with prediabetes and type 2 diabetes (T2D).

Optimization of a technology-supported physical activity intervention for breast cancer survivors: Fit2Thrive study protocol

Fit2Thrive is a theory-guided physical activity promotion trial using the Multiphase Optimization Strategy (MOST) to test efficacy for improving physical activity of five technology-supported physical activity promotion intervention components among breast cancer survivors. This trial will recruit 256 inactive breast cancer survivors nationwide. All participants will receive the core intervention which includes a Fitbit and standard self-monitoring Fit2Thrive smartphone application which will be downloaded to their personal phone. Women will be randomized to one of 32 conditions in a factorial design involving five factors with two levels: support calls (No vs. Yes), app type (standard vs. deluxe), text messaging (No vs. Yes), online gym (No vs. Yes) and Fitbit Buddy (No vs. Yes). The proposed trial examines the effects of the components on physical activity at 12 and 24weeks. Results will support the selection of a final package of intervention components that has been optimized to maximize physical activity and is subject to an upper limit of cost. The optimized intervention will be tested in a future trial. Fit2Thrive is the first trial to use the MOST framework to develop and test a physical activity promotion intervention in breast cancer survivors and will lead to an improved understanding of how to effectively change survivors' physical activity. These findings could result in more scalable, effective physical activity interventions for breast cancer survivors, and, ultimately, improve health and disease outcomes.
