Patients with JIA had poorer physical health compared to those with RA (adjusted difference [95% CI]: PCS \u22123.58 [\u22126.09 to \u22121.08]). Compared to the general population, PCS scores were lower in both JIA and RA (adjusted differences [95% CI]: JIA\u2013general population \u221215.70 [\u221218.21 to \u221213.19], RA\u2013general population \u221212.12 [\u221212.76 to \u221211.47]). Mental health measured by MCS was similar across the 3 groups. Average SF-6D utility levels were comparable in JIA and RA, but lower than in the general population. Similar proportions of patients with JIA and RA experienced improvements exceeding minimum clinically important difference (MCID) in SF-36 scale scores, PCS, MCS, and SF-6D after 6 months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Compared to patients with RA and the general population, patients with JIA had lower physical HRQOL 6 months after DMARD initiation.
