{Abstract}: <B>UNASSIGNED: </B>Obesity has been established as a significant risk factor for osteoarthritis. Anti-obesity medications (AOMs) have demonstrated efficacy in weight management. However, potential impact on osteoarthritis risk remains uncertain.<BR><B>UNASSIGNED: </B>This retrospective cohort study used Kythera data from NOV2022 to JULY2024. Patients with obesity using AOMs were identified through diagnosis and prescription claims for tirzepatide, semaglutide, or liraglutide between 1NOV2023 and 31JAN2024, with a 6-month follow-up to assess OA risk. OA risk, analyzed using Cox regression and propensity score matching, controlled for comorbidities and sociodemographic factors.<BR><B>UNASSIGNED: </B>There were 39,394 patients living with obesity using AOM (23,933 semaglutide 12,854 tirzepatide, 2,607 liraglutide) and 72,405 without AOM use. The adjusted osteoarthritis risk was 27% % lower in AOM users than in non-users (hazard ratio (HR) = 073, 95% CI (0.67-0.79), p < 0.01). Among AOMs, tirzepatide was associated with a significantly lower osteoarthritis (OA) risk compared to semaglutide (HR = 0.57, 95% CI: 0.50-0.65, p < 0.0001). Liraglutide was linked to a significantly higher OA risk vs tirzepatide (HR = 1.63, 95% CI: 1.23-2.15, p = 0.0007).<BR><B>UNASSIGNED: </B>AOM use was associated with a significantly lower risk of OA and may be an effective obesity management intervention.
