Food servings per day: geometric means (SE) and relative mean difference (95% CI) by group (TD and ID)^†

Food group	TD (n = 55) Adjusted geometric mean	ID (n = 48) Adjusted geometric mean	Relative mean difference(%) (95% CI)‡	P-value
Total vegetables	1.23 (1.05)	0.54 (1.06)	−51.41 (−67.68, −26.94)	<0.001
Total fruit	1.11 (1.06)	0.75 (1.07)	−29.31 (−54.17, 9.03)	0.12
Total fruit juice	0.34 (1.11)	0.34 (1.12)	−0.60 (−43.40, 74.54)	0.98
Sugar-sweetened beverages	0.20 (1.08)	0.16 (1.09)	−13.78 (−47.03, 40.36)	0.55
Snacks	1.41 (1.04)	1.08 (1.04)	−21.91 (−46.37, 13.69)	0.19

^†All analyses adjusted for BMI z-score, parent education (college and no college) and race (White and non-White).

^‡Mean difference is presented as per cent change from TD

BMI, body mass index; CI, confidence interval; ID, intellectual disability; SE, standard error; TD, typically developing.
