用Ｂ型超声波对桂中、桂南１０９３２名城镇居民进行体检，结果检出脂肪肝９８５例，发现率为９．０％，高峰年龄为５０－６９岁。大多数脂肪肝缺乏症状，９８５例伴发肥胖、酒精肝分别为４６６例（４７．３％）和２３８例（２４．２％），提示肥胖和慢性酒精中毒为国人脂肪肝的最常见原因。高血压病者脂肪肝发生率为２１．３％（９７／４５６）高于非高血压病者８．５％｛８８８／１０４７６）（Ｐ＜０．０１）。冠心病者发生率为１９．２％（５８／３０２）高于非冠心病者８．７％（９２７／１０６３０）（Ｐ＜０．０１），提示上二病与脂肪肝关系密切。
B-mode ultrasound was used to examine 10,932 urban residents in Guizhong and Guinan, and 985 fatty liver samples were detected. The detection rate was 9.0% and the peak age was 50-69 years old. Most of the fatty liver deficiency symptoms, 985 cases of obesity, alcoholic liver were 466 cases (47.3%) and 238 cases (24.2%), suggesting that obesity and chronic alcoholism are the most common causes of fatty liver in China. Hypertensive patients with fatty liver incidence was 21.3% (97/456) than non-hypertensive patients 8.5% {888/10476) (P <0.01). The incidence of coronary heart disease was 19.2% (58/302) higher than that of non-coronary heart disease 8.7% (927/10630) (P <0.01), suggesting that the disease is closely related to fatty liver.
