Aim 1: Evaluate the impact of universal preventive service coverage for obesity screening and counseling on weight loss, diabetes incidence, and diabetes outcomes, in patients with diabetes or at high risk for diabetes (defined by body mass index (BMI) ≥ 25). We will determine how the annual probability of receiving obesity and/or nutritional counseling (as defined by Current Procedural Terminology (CPT) code) changed pre- and post-policy across all insurers in a cohort of patients with diabetes and at high risk for diabetes. We hypothesize that individual patients are more likely to receive counseling following coverage implementation. Further, we hypothesize that patients who receive a greater number of face-to-face visits will have greater weight loss compared to those who receive fewer visits.
