非酒精性脂肪肝病患者体脂成分及膳食营养素摄入分析

目的探讨膳食营养因素、人体成分分析与非酒精性脂肪性肝病( NAFLD)发生的相关性。方法选取 NAFLD患者82例( NAFLD组),正常对照者82例(对照组),对被选人群进行问卷调查、体格测量、人体成分分析及肝脏超声检查。收集其体检报告,利用自行设计的健康状况调查表对个人一般状况进行调查,采用食物频率调查表调查其膳食种类和摄入量。结果与对照组比较,NAFLD组总能量、脂肪的摄入量、体质指数( BMI)、内脏脂肪面积( VFA)、体脂百分比( PBF)、腰臀百分比( WHR)均明显升高,血生化指标空腹血糖( FBG)、三酰甘油( TG)、丙氨酸转移酶( ALT)、天冬氨酸转移酶( AST)、极低密度脂蛋白( VLDL)及血尿酸( UA)均较
　　对照组明显上升,碳水化合物、蛋白质、膳食纤维、总胆固醇( TC)、尿素氮( BUN)、肌酐( Cr)两组间差异无统计学意义。结论通过NAFLD患者体脂成分测定及其膳食营养素摄入调查,NAFLD组人群膳食结构不够合理,人体成分分析与饮食因素相关性很大,高能量、高脂肪是NAFLD的膳食危险因素,肥胖、高血糖、高血脂、内脏脂肪面积高是NAFLD的患病危险因素。

Body fat composition and dietary nutrients intake analysis with nonalcoholic fatty liver disease

Objective To study the correlation between diet nutrition,body composition analysis and the occurrence of nonalcoholic fatty liver disease ( NAFLD) . Methods 82 cases of NAFLD patients and 82 cases of normal con-trols were selected. Questionnaire survey, physical measurement, body composition and liver ultrasound were con-ducted for selected population. The physical examination reports of selected population were collected. The general situation of individuals and different kinds of food and the intake amount was investigated by using self-designed health questionnaire and food frequency questionnaire, respectively. Results Compared with normal control group, the daily intake of total energy and fat for per person, the body mass index (BMI),visceral fat area(VFA), percentage of body fat( PBF) ,waist hip ratio( WHR) among the investigated subjects with NAFLD were significan-gtly higher. Fasting blood glucose(FBG), triglycerides(TG),alanine transaminase(ALT),aspartate transaminase (AST),very low density lipoprotein(VLDL) and blood uric acid(UA) were increased than NC group. There was no statistical significance in carbohydrates, protein, dietary fiber, total cholesterol ( TC ) , blood urea nitrogen ( BUN) , creatinine ( Cr) between the two groups. Conclusion By the determination of body fat composition and investigation of dietary nutrients intake of the NAFLD patients,this paper discovers that the intake of basic nutrients among the investigated subjects is adequate to satisfy the demand of human body, but the diet structure is unreason-able and some nutrients are either excessive or deficient. The correlation between the human body composition anal-ysis and dietary factors is very large. The intake of high energy and high fat are the diet risk factors of NAFLD. O-besity, hyperglycemia, hyperlipidemia, high visceral fat area are the risk factors of NAFLD.
