【摘要】 目的了解超重、肥胖儿童脂肪肝的发生情况,为预防和控制儿童脂肪肝的发生提供依据。方法选择北京市3所中学和2所小学,根据2005-2006年中小学生身高、体重体检结果进行体重正常、超重和肥胖的筛选,对自愿参加的1011名7~15岁学生进行身高、体重的测量,并进行肝脏B型超声检查和血脂、ALT的测定。结果超重、肥胖儿童脂肪肝检出率明显高于体重正常儿童;超重、肥胖儿童脂肪肝组血脂水平明显高于非脂肪肝组,除血清总胆固醇(TC)外,其余指标差异均有统计学意义(P值均<0.01)。结论超重和肥胖儿童脂肪肝检出率明显高于体重正常儿童。应加强超重和肥胖儿童肝脏B型超声的检查,预防脂肪肝的发生。更多还原

【Abstract】 Objective To explore the prevalence of fatty liver among overweight and obese children,and to provide evidence for prevention of obesity and fatty liver.Methods Normal-weight,overweight and obese children were selected from three middle schools and two primary schools in Beijing,according to the results of height and weight in 2005-2006 students’ physical examination.Height and weight,liver ultrasound B scans,serum lipids and ALT were examined for 1 011 volunteers aged 7-15 years old.Results The prevalence of fatty liver in overweight and obese children was obviously higher than that in normal-weight children.Except for TC,there were significant differences of the level of serum lipids between fatty liver and non-fatty liver children(P<0.01).Conclusion Compared with normal-weight children,the prevalence of fatty liver in overweight and obese children is higher.Examination with liver ultrasound B scans should be strengthened to prevent the incidence of fatty liver.更多还原
