Disability, Physical Activity, and Their Correlates in Patients With Inflammatory Bowel Disease: A Portuguese Cross-Sectional Survey

Abstract

Knowledge about disability and physical activity is critical for enhancing self- and clinical management of inflammatory bowel disease, but the interplay between the two is unknown. This study aimed to explore the correlates of disability and physical activity in patients with inflammatory bowel disease. A cross-sectional online survey was conducted in 2019 in Portuguese patients (n = 108) capturing disability, clinical factors including disease status and comorbidities, physical activity habits, and barriers. The magnitude of disability was moderate (mean [95% confidence interval] = 41.85 [38.39, 45.31]). Disease activity and comorbidities were the most important predictors of disability (Model 2, F(102) = 20.285, p < .001, R2 = 0.499, R2adj = 0.443). About 62% of the participants engaged in moderate (31.5%) to vigorous (30.6%) physical activities. Perceived effort to engage in physical activities was the sole predictor of total weekly physical activity (R2 = 0.070, R2adj = 0.044, p = .006). The amount of disability and physical activity were poorly associated (ρ = -0.144, p = .068). Findings encourage gastroenterology nurses and other healthcare providers involved in the comprehensive care of patients with gastrointestinal disorders to recommend regular physical activity to these patients as part of an overall health enhancement strategy. Disability and back pain should be given further attention.
