- Note: ICF Intracellular fluid, ECF Extracellular fluid, TBW Total body water. a; TFI was compared with the recommendation for the adequate water intake (AI) for TFI set by Chinese Nutrition Society (2013) (adult male: 1700 mL; adult female: 1500 mL). Mean and standard deviation (SD) was used to describe variables in normal distribution; percentile (P50 [P25, P75]) was used to describe variables in skewness distribution; and count data were presented as n (percentage). b, means the statistical value Z of Kruskal-Wallis test for comparison of indexes between sexes. c, means the statistical value t of Student’s t-test for comparison of indexes between sexes. d, means the statistical value χ2 of χ2 test for comparison of indexes between sexes
