With broader FDA approvals for obesity management, it is essential to examine utilization patterns across diverse patient populations to ensure equitable access. This study explores GLP-1 use patterns in U.S. adults with diabetes and/or obesity to identify potential access barriers and demographic differences. Methods: We conducted a cross-sectional analysis of U.S. adults ≥18 years with diabetes and/or obesity (BMI≥30) using National Health and Nutrition Examination Survey (NHANES) 2017–March 2020 data (n=4,362). Prescription files identified GLP-1 users. Primary outcomes were utilization rates across demographic and clinical factors (age, gender, race/ethnicity, income, education, BMI). Statistical analysis was performed using chi-square tests (p< 0.05). One GLP-1 user without obesity or diabetes was excluded. Results: GLP-1 use was 1.5% in those with diabetes and/or obesity (67/4,362). Significant differences existed by clinical sub-group: lowest in obesity-only group (2/2,939, 0.1%) versus diabetes-only (17/674, 2.5%) and diabetes with obesity (48/749, 6.4%, p< 0.001). Age was significant, with lower use in 18-39 years (1/1,170, 0.1%), versus ages 40-59 (34/1,514, 2.2%) and age ≥60 (32/1,624, 2.0%, p< 0.001). Class II/III Obesity had higher use than Class I group (33/1,783, 1.9% vs. 17/1,854, 0.9% respectively, p=0.008). Use across race/ethnicity varied from 0.7% (Asian) to 1.8% (Black/White) but remained non-significant (p=0.493). Income, education, and gender showed no significant associations. Discussion: Our analysis reveals critically low GLP-1 utilization (1.5%) with a 64-fold difference between diabetes with obesity patients (6.4%) versus obesity-only patients (0.1%), consistent with diabetes-centered prescribing patterns when obesity approvals were limited. The virtual absence of use in young adults (0.1%) was striking, representing a gap in prevention opportunities in a population with rising obesity prevalence. Although racial disparities were non-significant, the small sample size of GLP-1 users may mask access barriers rather than reflecting true equity. Future research should employ larger datasets and claims analyses, particularly among complex patient populations such as IBD patients with corticosteroid-related obesity risks.
