Cardiorespiratory fitness and mortality in rheumatoid arthritis
Liff, Marthe Halsan (Doctoral theses at NTNU;2022:128, Doctoral thesis, 2022)Background Rheumatoid arthritis (RA) is an autoimmune inflammatory disease that affects synovial joints and internal organs. It affects around 1% of the population, and the disease is associated with increased all-cause ... -
Cardiorespiratory fitness in patients with rheumatoid arthritis is associated with the patient global assessment but not with objective measurements of disease activity
Liff, Marthe Halsan; Hoff, Mari; Fremo, Thomas; Wisløff, Ulrik; Thomas, Ranjeny; Videm, Vibeke (Journal article; Peer reviewed, 2019)Objective Patients with rheumatoid arthritis (RA) suffer from more cardiovascular disease (CVD), and develop cardiovascular risk factors at an earlier age than the general population. Cardiorespiratory fitness (CRF) is an ... -
An Estimation Model for Cardiorespiratory Fitness in Adults with Rheumatoid Arthritis
Liff, Marthe Halsan; Hoff, Mari; Fremo, Thomas; Wisløff, Ulrik; Videm, Vibeke (Peer reviewed; Journal article, 2020)Purpose Cardiopulmonary exercise testing of peak oxygen uptake (V˙O2peak) is the gold standard to measure cardiorespiratory fitness (CRF). For resource-intensive evaluation, equations estimating CRF (eCRF) may be used. ... -
Inflammation mediates approximately one quarter of excess relative all-cause mortality in persons with rheumatoid arthritis: the Trøndelag Health Study
Videm, Vibeke; Houge, Ingrid Sæther; Liff, Marthe Halsan; Hoff, Mari (Peer reviewed; Journal article, 2022)Inflammation may contribute to excess mortality in rheumatoid arthritis (RA) patients. We investigated associations to all-cause mortality of the inflammation markers high-sensitivity C-reactive protein (CRP), lactoferrin ... -
Reduced cardiorespiratory fitness is a mediator of excess all-cause mortality in rheumatoid arthritis: The Trøndelag Health Study
Liff, Marthe Halsan; Hoff, Mari; Wisloff, Ulrik; Videm, Vibeke (Peer reviewed; Journal article, 2021)Objectives Investigate if low cardiorespiratory fitness (CRF) was associated with and acted as a mediator of excess all-cause mortality rate in persons suffering from rheumatoid arthritis (RA) compared with the general ... -
Relative importance of inflammation and cardiorespiratory fitness for all-cause mortality risk in persons with rheumatoid arthritis: the population-based Trøndelag Health Study
Videm, Vibeke; Liff, Marthe Halsan; Hoff, Mari (Peer reviewed; Journal article, 2023)Objective Inflammation and reduced cardiorespiratory fitness (CRF) are associated with increased mortality rates in rheumatoid arthritis (RA). We aimed at directly comparing the relative importance of inflammation and ... -
Use of the Behavioral Regulation in Exercise Questionnaire-2 to assess motivation for physical activity in persons with rheumatoid arthritis: an observational study
Videm, Vibeke; Hoff, Mari; Liff, Marthe Halsan (Peer reviewed; Journal article, 2022)Arthritis patients may show little motivation for physical activity (PA), resulting in a sedentary lifestyle. The primary objective of the study was to investigate whether motivation for PA and fulfillment of PA recommendations ...
