某地区中老年体检者高血脂及脂肪肝检出率分析

The investigation on distribution of hyperlipidemia and fatty liver in middle-aged and elderly

目的探讨高脂血症及非酒精性脂肪肝在中、老年人的分布规律。方法对563名体检者空腹12h,抽取血液标本检验血脂,做腹部B超检查。按照年龄分为A组(45～59岁),B组(≤98岁)。结果563人共发现脂肪肝315例,占56%。其中A组273人中发现脂肪肝141例(51.6%);B组290例中脂肪肝174例(60%)。A组血脂升高例数多于B组(P<0.01)。B组血脂正常而脂肪肝例数高于A组。甘油三酯升高是脂肪肝的主要因素。结论中年人血脂增高者多于老年人,老年人脂肪肝高于中年人。

Objective To investigate the distribution of hyperlipidemia and nonalcoholic fatty liver in middle-aged and elderly.Methods 563 cases undergoing physical examination got empty tee stomach for 12 hours, their blood specimens were sampled to check their blood lipid, and received the abdominal B-ultrasonic examination. They were divided into 2 groups： group A （45-59yr） and group B （≤98yr） according to the age. Results 315 of 563 cases had fatty liver：, group A,141/273 （51.6%）; group B, 174/290（60%）. The difference of case- numbers of high blood lipid between group A and group B was significant （P〈0.01）; the case- number of fatty liver with normal blood lipid in group B was more than in group A. TG value increase was a main factor of fatty liver. Conclusion The case- numbers of high blood lipid in middle-aged is more than in elderly, the case- number of fatty liver in elderly is more than in middle-aged.
