健康人HDL-ch的含量,女性高于男性。中年组(45～59岁)HDL-ch平均值较低,男比女低,这与中国人男性45岁以后患冠心病(CHD)多于女性相吻合。冠心病及脑中风HDL-ch含量比健康人低(P<0.05),显示HDL-ch含量与冠心病和脑中风发生率呈负相关。运动员HDL-ch含量明显高于健康人(P<0.01),HDL-ch含量均值高于不易患动脉粥样硬化(AS)的8种哺乳动物均值(60.40mg/dl)。 HDL-ch content of healthy people, women than men. The median HDL-ch in middle age group (45-59 years old) was lower than that in men, which was more consistent with CHD than female in Chinese men after 45 years of age. The content of HDL-ch in coronary heart disease and stroke was lower than that in healthy people (P <0.05), which showed that HDL-ch content was negatively correlated with the incidence of coronary heart disease and stroke. The content of HDL-ch in athletes was significantly higher than that in healthy people (P <0.01), and the mean HDL-ch content was higher than the mean of eight kinds of mammals (60.40mg / dl), which were less susceptible to atherosclerosis (AS).
