Abstract
Abstract Background Physical activity (PA) may benefit people with inflammatory bowel diseases (IBD) by improving immunological response, musculoskeletal function, and psychological health. Aims We distilled available evidence on the efficacy and safety of PA to improve health-related quality of life (HRQoL) and relieve persistent symptoms of fatigue, joint pain, abdominal pain, stress, anxiety, and depression in individuals with quiescent/mild IBD. Methods We searched for trials in eight databases and trial registries. Trials using PA as an adjunct therapy in the management of adults (≥18 years) with quiescent or mild IBD, published in English between 2011 and 2023 were identified. Summary effect estimates were expressed as standardized mean difference (SMD) or mean difference (MD) with 95% confidence interval (CI) using random-effects model. Results From the 10,862 citations retrieved, we included seven randomized controlled trials (RCTs) and one non-RCT. There was no evidence of benefit of PA on HRQoL (SMD 0.34, 95%CI −0.08 to 0.77; I2 57%); high heterogeneity was noted among included trials. PA was found to be efficacious in reducing anxiety (SMD −0.35, 95%CI −0.65 to −0.05; I2 0%). There was insufficient evidence to make conclusions regarding changes in fatigue, joint pain, abdominal pain, stress, and depression. All trials deemed physical activity safe. Conclusions PA contributes to reducing anxiety in quiescent/mild IBD. There is marked heterogeneity in methodology among trials investigating PA in adults with quiescent/mild IBD. This review highlights the need for consistent definitions of PA types and intensities in this field of research.
