Participants were classified into four groups\u2014Normal, Obesity, Sarcopenia, and Sarcopenic obesity\u2014based on sarcopenia criteria, which included skeletal muscle mass index, grip strength, and physical function, as well as obesity criteria defined by body fat percentage.

The median disease activity score suggested that remission was achieved in all groups. The TUG and HAQ\u2010DI scores were highest in the Sarcopenic obesity group, showing a significant difference compared with all other groups. Other physical function assessments and PROs were also worse in the Sarcopenic obesity group compared with all other groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>\n                      The proportion of sarcopenic obesity in the present study population of well\u2010controlled RA patients was 8.4%.
