Fat Free Mass (g/week)	V1–V2 rate	120 (24.2)	120 (32.4)	0.96

Fat Mass (g/week)	V2–V3 rate	7.56 (6.89)	8.86 (4.84)	0.45
Percent Body Fat (%/week)	V1–V2 rate	0.39 (0.36)	0.96 (0.51)	<0.001

V1 = Visit 1 at term or term corrected age (preterm participants)

V2 = Visit 2 at 3–4 months (preterm corrected age)

V3 = Visit 3 at 4 years

Data are reported as mean (SD).

The p-value is calculated from two-sample t-test.
