In 41 healthy men aged 50 fasting serum HDL cholesterol, total cholesterol, LDL + VLDL cholesterol and triglycerides increased by 8.3, 9.6, 9.9 and 11.3%, respectively (all P less than 0.001), after 30 min standing compared to 30 min in the supine position. These findings can be fully explained by decrease in plasma volume on changing from lying to the erect position. However, the cholesterol ratio (HDL cholesterol X 100/LDL + VLDL cholesterol) was not influenced by posture and should be evaluated instead of cholesterol fractions if the conditions for blood sampling were not controlled.
在41名50岁健康男性中，与仰卧30分钟相比，站立30分钟后，空腹血清高密度脂蛋白胆固醇、总胆固醇、低密度脂蛋白+极低密度脂蛋白胆固醇和甘油三酯分别升高了8.3%、9.6%、9.9%和11.3%（所有P值均小于0.001）。这些发现可以通过从卧位变为直立位时血浆量的减少得到充分解释。然而，胆固醇比值（高密度脂蛋白胆固醇×100/低密度脂蛋白+极低密度脂蛋白胆固醇）不受体位影响，如果采血条件未得到控制，应评估该比值而非胆固醇组分。
