DWI: Daily water intake; N: number of participants; HCT: haematocrit; haematocrit was categorized using 0.45±0.05% or 0.41±0.05% for males and females respectively; Hb: haemoglobin; Low Hb (anaemia) was defined as Hb < 12.5 g/dl or 11.5 g/dl for males and females respectively; proportions in categories were compared using the Chi-square test. ∗Indicates that TBW significantly differed across the group sub-categories at p < 0.05.
