		PPDS groups^a			ORs for inadequate GWG in IBD compared to non-IBD with low intake of PPDS
	N (obs)	1	2	3	aOR (95% CI) low compared to high PDDS	aOR (95%) middle compared to high PPDS
Inadequate GWG (%)
Non-IBD	68,680	6923 (20.3)	3221 (18.4)	3067 (18)
IBD	341	68 (30.8)	22 (31.4)	14 (28)	2.35 (1.23, 4.49)	1.38 (0.64, 2.99)

OR adjusted for mothers’ education and age, ^aGroup 1 = quartile 1 + 2, group 2 = quartile 3, group 3 = quartile 4, highest PPDS group (group 3) was used as reference group, GWG gestational weight gain, PPDS proportion of protein from dairy sources
Plural birth and extreme energy intake and 50 kg < GWG < −30 kg excluded
