Impact of Obesity on Ostomy-Related Problems^a,^b

	Time of Survey		Before Surgery
	Prevalence of problem among non-obese	RR (95% CI)	Prevalence of problem among non-obese	RR (95% CI)
>30 min needed to conduct daily stoma care	19%	1.01 (0.53–1.92)	19%	1.13 (0.53–2.39)
Interference with clothing	32%	1.88 (1.38–2.56)	36%	1.37 (0.96–1.97)
Other problems	21%	1.68 (1.07–2.65)	23%	1.48 (0.89–2.50)

Information missing: Time to conduct daily care n=2, interference with clothing n=4, other problems n=15

Poisson regression model with obesity (yes/no) at time of survey or before surgery, adjusted for gender, age, time since surgery, Charlson-Deyo comorbidity score, and tumor site (rectum vs. colon). Models for “Other problems” also adjusted for at least one complication > 30 days from the surgery

BMI=body mass index; CI=confidence interval; RR=risk ratio
