Objective To investigate the clinical significance of fatty liver detected by B-mode ultrasound in physical examination. Methods The clinical data of 898 healthy persons selected from Jan to Dec in 2014 in our hospital were retro-spectively analyzed, all subjects were used SA-1500 black and white B-mode ultrasound diagnostic equipment, and were di-vided into groups by age for ≤20 years old, 21~30 years old, 31~40 years old, 41~50 years old, 51~60 years old, the inci-dence of fatty liver in different gender of the ages were compared. The survey subjects were divided into fatty liver group and non-fatty liver group, the incidence of complications in the two groups were compared. Results The incidence of fatty liver was 17.82%. The older the subject was, the higher the incidence of fatty liver was. There was significant difference in the inci-dence of fatty liver at different ages (P<0.05). The incidence of fatty liver in male was higher than that of female, the difference was statistically significant (P<0.05). The incidence of diabetic, coronary heart disease, hyperlipidemia, hypertension in fatty liver group were higher than those of non-fatty liver group, the difference were statistically significant (P<0.05). Conclu-sion Elderly and men should pay more attention to the prevention of fatty liver, form healthy eating habits and lifestyle, con-trol weight and diet, take regularly physical examination, it can reduce the incidence of fatty liver.%目的：分析健康体检中经B超检出脂肪肝的临床意义。方法对2014年1~12月来我院进行健康体检者898例的临床资料进行回顾性分析，所有研究对象B超检查均使用SA-1500黑白超声诊断仪，将其按照年龄分为≤20岁、21~30岁、31~40岁、41~50岁、51~60岁年龄段，比较各年龄段不同性别脂肪肝发生率，再将研究对象分为脂肪肝组和非脂肪肝组，比较两组并发症发生率。结果本组脂肪肝发病率为17.82%（160/898）。研究对象的年龄越大，脂肪肝的发生率越高，各年龄段脂肪肝发生率差异有统计学意义（P<0.05）；男性脂肪肝患病率明显高于女性，差异有统计学意义（P<0.05）。脂肪肝组患者糖尿病、冠心病、高脂血症、高血压发生率与非脂肪肝组比较均较高，两组差异有统计学意义（P<0.05）。结论中老年人和男性应更注意脂肪肝的预防，形成健康的饮食习惯及良好的生活习惯，控制体重和饮食等预防脂肪肝，定期去正规的医院进行健康体检，可降低脂肪肝的发生率。
