Patient experiences with the role of physical activity in inflammatory bowel disease: results from a survey and interviews

Table 3 Results of multiple linear regression of the association between physical activity with disease activity as continuous variables, for CD and UC

	CD (n = 176)		UC (n = 162)
	β-coefficient (95% CI)^a	p value	β-coefficient (95% CI)^a	p value
Total physical activity score
Crude	− 0.406 (− 0.698 to 0.114)	0.007	− 0.006 (− 0.015 to 0.003)	0.162
1	− 0.395 (− 0.693 to 0.097)	0.010	− 0.005 (− 0.014 to 0.004)	0.293
2	− 0.375 (− 0.668 to 0.081)	0.013	− 0.003 (− 0.013 to 0.006)	0.490

CD disease activity scores can range from 0 to > 450 and UC disease activity scores can range from 0 to 19
Bold values are significant
CD Crohn’s disease, UC ulcerative colitis, CI confidence interval
^aPer 100 point increase in total physical activity score
Model 1: adjusted for age (years), gender (m/f), BMI (kg/m²) and education level (low/middle/high)
Model 2: as model 1 plus age at diagnosis (years), medication use (yes/no) and previous IBD-related surgery (yes/no)
