+# Medicaid coverage expansion for GLP-1s reduces racial prescribing disparities from 49 percent to near-parity because insurance policy is the primary structural driver not provider bias
+
+Before Massachusetts Medicaid (MassHealth) expanded GLP-1 coverage for obesity in January 2024, Black patients were 49% less likely and Hispanic patients were 47% less likely to be prescribed semaglutide or tirzepatide compared to White patients (adjusted odds ratios). After the coverage expansion, these disparities 'narrowed substantially' according to the authors. This natural experiment design provides stronger causal evidence than cross-sectional studies because it isolates the policy change as the intervention. The magnitude of the pre-coverage disparity (nearly 50% reduction in likelihood) and its substantial narrowing post-coverage demonstrates that structural barriers—specifically insurance coverage—are the primary driver of racial disparities in GLP-1 prescribing, not implicit provider bias alone. The study was conducted at a single large tertiary care center, so generalizability requires replication, but the pre-post design within the same institution controls for provider composition and practice patterns. Separate tirzepatide prescribing data showed adjusted odds ratios vs. White patients of 0.6 for American Indian/Alaska Native, 0.3 for Asian, 0.7 for Black, 0.4 for Hispanic, and 0.4 for Native Hawaiian/Pacific Islander patients, confirming the disparity pattern across multiple racial/ethnic groups.

+# Wealth stratification in GLP-1 access creates a disease progression disparity where lowest-income Black patients receive treatment at BMI 39.4 versus 35.0 for highest-income patients
+
+Among Black patients receiving GLP-1 therapy, those with net worth above $1 million had a median BMI of 35.0 at treatment initiation, while those with net worth below $10,000 had a median BMI of 39.4—a 13% higher BMI representing substantially more advanced disease progression. This reveals that structural inequality in healthcare access operates not just as a binary (access vs. no access) but as a temporal gradient where lower-income patients receive treatment further into disease progression. The 4.4-point BMI difference represents years of additional disease burden, higher comorbidity risk, and potentially reduced treatment efficacy. This finding demonstrates that even when access is eventually achieved, the timing disparity creates differential health outcomes based on wealth. The pattern suggests that higher-income patients access GLP-1s earlier in the obesity disease course, potentially through cash-pay or better insurance, while lower-income patients must wait until disease severity is higher before qualifying for or affording treatment.
