Behavioural and psychological predictors of the commonly occurring ROME III functional gastrointestinal disorders among eating disorder patients

ROME III FGID	Predictors	B	Wald	υ	P	OR	95%CI
A1: Functional Heartburn	Somatisation	0.13	5.31	1	0.021	1.14	1.02	1.27
B1a: Postprandial Distress Syndrome	Starvation	0.58	6.99	1	0.008	1.79	1.16	2.76
	Exercise	-0.57	6.23	1	0.013	0.56	0.36	0.88
	Depression	0.67	4.73	1	0.030	1.07	1.01	1.14
C1: Irritable Bowel Syndrome	Laxatives	0.46	5.05	1	0.025	1.58	1.06	2.35
C5: Unspecified Functional Bowel Disorder	Somatisation	-0.19	7.21	1	0.007	0.83	0.73	0.95

The potential predictors: Age, BMI, binge eating behaviour, vomiting, depression and state and trait anxiety did not predict any common functional gastrointestinal disorders (FGIDs). There were no significant predictors of presence of three or more FGIDs.
