We examined gender‑age‑specific differences in ASPR, ASIR, and ASDR and the relationships between RA‑related DALYs and risk factors across strata.

Although higher sociodemographic index (SDI) regions bore a greater RA burden overall, lower SDI regions experienced more rapid increases. Across all metrics, women - particularly those aged ≥60 years - demonstrated higher rates than men. 'Smoking' emerged as a vital risk of DALYs across age groups, genders, and regions.
