Introduction
Disability is a multidimensional concept encompassing physical, psychological, and social limitations that can significantly burden individuals living with inflammatory bowel disease (IBD). However, as disability is shaped by various factors—including cultural, social, and healthcare-related influences that can differ between countries—its prevalence and characteristics may vary globally.
Aims & Methods
We aimed to meta-analyse global data on prevalence of moderate-to-severe disability (MSD) to explore differences in disability prevalence and characteristics by country, IBD subtype, disease activity. MEDLINE EMBASE, EMBASE Classic (from inception to 1st December 2024) to identify cross-sectional and case-control studies reporting the prevalence of MSD based on validated tools (IBD–Disk and IBD-Disability Index) in adult patients (≥18 years) with confirmed IBD. Data were extracted, and pooled prevalence (PP), odds ratios (OR), and 95% confidence intervals (CIs) were calculated.
Results
The search strategy generated 3089 citations. From these, 160 individual articles appeared to be relevant to the study question and 17 fulfilled the eligibility criteria, containing 8225 patients with IBD recruited from 11 different countries. The pooled prevalence of MSD in patients with IBD was 29.6% (95% CI 22.6-37.1%; I2=98.0%, p<0.01), with no evidence of funnel plot asymmetry (Egger test, p=0.10). The lowest pooled prevalence of MSD was 7.0% in one Dutch study from the Netherlands, and the highest 51% and 52% in two studies from China and Italy, respectively. The pooled prevalence of MSD was higher in patients with IBD with active disease (56.9%, 95% CI 20.3-89.7%, I2 = 93.0%, p<0.01) compared with those with inactive disease (27.0%, 95% CI 3.3-62.0%, I2 = 93.0%, p<0.01). Based on three studies that reported MSD prevalence in both active and inactive disease, active IBD increased the odds of MSD more than threefold (odds ratio 3.13, 95% CI 1.74-5.64).
Conclusion
The global prevalence of MSD in the IBD population is 29.6%, and even higher among patients with active disease. These findings underscore the value of incorporating disability assessment into both clinical decision-making and routine therapeutic response —especially in the context of disease modification trials.
