Total body water (TBW), lean body mass (LBM), and triglyceride mass were measured in 23 5-yr-old baboons (13 females and 10 males). Male baboons weighed more, had more LBM, more TBW, and contained less triglyceride mass per unit body weight than female baboons. Among all baboons, triglyceride mass per unit body weight ranged from 2.4 to 33.5%. The ratio TBW:LBM ranged from 0.70 to 0.92, increasing (r = 0.98) with increased body triglyceride content (both percent and absolute mass) in both male and female baboons. However, the water content per unit weight of tissues free of fat cells (liver, lungs, kidneys, central nervous system, eyes, tongue) was nearly constant at 0.73 +/- 0.02. The increase in TBW:LBM is more than can be expected from the water in the increased adipose tissue mass. We conclude that TBW:LBM is not constant but is influenced by body triglyceride content in baboons.
对23只5岁的狒狒（13只雌性和10只雄性）测量了总体水（TBW）、瘦体重（LBM）和甘油三酯质量。雄性狒狒体重更重，有更多的瘦体重、更多的总体水，且每单位体重所含甘油三酯质量比雌性狒狒少。在所有狒狒中，每单位体重的甘油三酯质量范围为2.4%至33.5%。总体水与瘦体重的比值范围为0.70至0.92，在雄性和雌性狒狒中均随着身体甘油三酯含量（百分比和绝对质量）的增加而增加（r = 0.98）。然而，不含脂肪细胞的组织（肝脏、肺、肾脏、中枢神经系统、眼睛、舌头）的每单位重量含水量几乎恒定在0.73±0.02。总体水与瘦体重比值的增加幅度超过了增加的脂肪组织质量中的水所能预期的幅度。我们得出结论，在狒狒中，总体水与瘦体重的比值并非恒定不变，而是受身体甘油三酯含量的影响。
