Introduction and Objective: Low carbohydrate eating plans can improve glycemic control, promote weight loss, and are associated with improved cardiometabolic health and all-cause mortality. Individuals with food insecurity often lack resources to adopt the necessary dietary changes. We aimed to implement and evaluate a quality improvement (QI) program, called Jumpstart, to support patients with T2D and food insecurity to adopt a lower carbohydrate, healthier diet.
Methods: We conducted a cohort-based QI program aimed at promoting dietary change in adult patients with T2D. Eligible adults had a diagnosis of T2D, self-identified food insecurity or low income, and received care from a clinic participating in the Michigan Collaborative for Type 2 Diabetes, a statewide T2D quality improvement collaborative. The 3-month program included home grocery delivery, $80/month of healthy food purchasing credits, and nutrition education materials on lower carbohydrate diets. Medical records for 6-months prior to enrollment through 12-months after enrollment were obtained and differences in weight and HbA1c were assessed using two-tailed paired t-tests (alpha=0.05) comparing baseline to post-program measurement.
Results: Among the 83 participants who completed the program the mean age was 57 years ±13, 72% identified as female, and 90% identified as white. Reduction in HbA1c from baseline was 0.47%±1.59% at or after 6-months from program enrollment (p=0.017, n=68). Reduction in weight at 9-months or later was 2.1%±4.4% (p=0.006, n=38) correlating to 2.2lbs of weight lost on average.
Conclusion: Participants in the Jumpstart program experienced sustained reduction in HbA1c and body weight. Programs that use grocery delivery with nutrition education may successfully promote long term dietary change and improve health among adults with T2D and other vulnerable populations.
