Accelerated Muscle Strength Decline and Reduced Lean Mass in Adults with Treated Inflammatory Bowel Disease: A NHANES Study

Muscle loss in patients with treated IBD was related to reduced lean body mass and a pattern consistent with faster age-related neuromuscular loss. These findings highlight an opportunity for the early identification of functional vulnerability using continuous muscle phenotypes and emphasize the potential role of modifiable lifestyle interventions, including physical activity, resistance training, and nutritional optimization, in preserving muscle health and improving long-term functional decline in adults with IBD.
