Comparison of the mean hydration factor values in older non-Caucasian adults to several hydration factors cited in the literature.

FMI Category	Mean	0.732 Value from Chemical Analysis	0.725 Value from “Grand Mean”	0.734 Value from Older French Adults
Normal (n = 44)	0.750 ± 0.039	p = 0.003	p ≤ 0.001	p = 0.008
Excess fat (n = 193)	0.748 ± 0.031	p ≤ 0.001	p ≤ 0.001	p ≤ 0.001
Obesity (n = 175)	0.747 ± 0.035	p ≤ 0.001	p ≤ 0.001	p ≤ 0.001
Total sample (n = 412)	0.748 ± 0.033	p ≤ 0.001	p ≤ 0.001	p ≤ 0.001

FMI = fat mass index; comparison between mean hydration factor values and several hydration values cited in the literature by a one-sample t-test.
