摘要： 【目的】 了解南宁市超重、肥胖儿童非酒精性脂肪肝(nonalcoholic fatty liver disease,NAFLD)的检出情况。【方法】 对本院小儿内分泌科门诊就诊的180例超重、肥胖患儿进行身高、体重、腰围等测量,同时进行肝肾功能、血糖、胰岛素、肝脏B超等相关检测。【结果】 180例患儿中B超明确脂肪肝66例(男42例,女24例),非脂肪肝114例(男64例,女50例),NAFLD检出率为36.7%(66/180),其中男童检出率为39.6%(42/106),女童检出率为32.4%(24/74),男女差异无统计学意义(χ²=0.394,P=0.319);脂肪肝组体质指数、腰围、血压、血脂等指标均高于非脂肪肝组。【结论】 南宁市超重、肥胖儿童的NAFLD的发生率为36.7%,控制儿童超重、肥胖的发生,是防治儿童青少年NAFLD的重要措施;谷丙转氨酶能否用于超重、肥胖儿童NAFLD早期识别的依据值得探讨。
