【摘要】 目的 探讨高中生谷丙转氨酶(ALT)升高相关因素。方法 分析大连市2005年高考体检数据。 结果 17954名高考学生中检出ALT升高49名，其中乙肝表面抗原(HBsAg)阳性7名(男3名，女4名)，HBsAg阴性42名(男35名，女7名)；HBsAg阳性组ALT平均值(193.7IU/L)高于HBsAg阴性组(139.5IU/L)；其他相关数据(体重指数、平均收缩压、平均舒张压)HBsAg阴性组均显著高于HBsAg阳性组；近5年大连市高考学生体检HBsAg阳性检出率有所下降，而体重指数(BMI)则呈持续升高趋势。结论 肥胖对高中生肝脏功能的影响日渐突出，成为继心、脑血管疾病之后又一重大疾病—脂肪肝的主要病理基础，肥胖的防治需要包括学校、学生、家长的社会参与，充分认识其对健康的影响、增强防治意识有着重要的意义。

In other related data (BMI, the average systolic pressure, the average diastolic pressure), the negative group is marked higher than the positive group. In the later 5 years, the positive rate of HBsAg is descended. The BMT is goes up.Conclusion It is outstanding day by day that the obesity influences the liver function. It became a great disease after heart and cerebral blood vessel diseases.
