Criterion Validity and Responsiveness of Estimated Cardiorespiratory Fitness Models in Patients with Inflammatory Joint Disease.

ABSTRACT: Cardiorespiratory fitness (CRF) is an excellent marker of overall health. This study aimed to assess criterion validity and responsiveness of estimated CRF models (eCRF) in patients with inflammatory joint disease (IJD). CRF was measured directly as peak oxygen uptake (VO_2peak) by a Cardiopulmonary Exercise Test (CPET), while one generic eCRF model (eCRF_GEN) and two disease-specific eCRF models (eCRF_ALT and eCRF_PGA) were used to estimate CRF at baseline and after 3 months in 55 Norwegian patients with IJD. Moderate correlations were observed between eCRF_GEN, eCRF_ALT, eCRF_PGA, and VO_2peak at baseline (ICC 0.60, 0.64 and 0.62, respectively) and 3 months (ICC 0.62, 0.65 and 0.57, respectively). All eCRF mo
