摘要
目的构建非酒精性脂肪性肝病患者生活方式关系模型,为医护人员对相关人群进行健康教育和疾病干预提供依据。方法采用方便抽样法,从体检人群中抽取205例非酒精性脂肪性肝病患者及231例正常人群,对其生活方式进行问卷调查,对2组人群人口学资料进行单因素分析,通过结构方程模型建模方法构建非酒精性脂肪性肝病患者生活方式关系模型。结果模型拟合良好。模型结果显示,与非酒精性脂肪性肝病有直接效应的因素包括体质量指数、不良饮食习惯、良好饮食习惯、吸烟状况,效应值分别为-0.45,-0.16,0.19,-0.09;行为方式与非酒精性脂肪性肝病之间存在间接效应,效应值为0.20,体质量指数为其中的中介变量。结论非酒精性脂肪性肝病受体质量指数、饮食习惯及吸烟状况的直接影响,行为方式通过体质量指数的中介作用间接影响非酒精性脂肪性肝病,提示可采取以下措施预防和控制非酒精性脂肪性肝病:经由改善行为方式控制体质量,调节饮食结构,戒烟。
Objective To develop a model of factors related to lifestyle for patients with nonalcoholic fatty liver disease （NAFLD） in Guangzhou, and provide theoretical basis for medical care interventions. Methods A total of 205 patients with NAFLD and a general population of 231 having physical examinations in two general hospitals in Guangzhou were recruited by convenient sampling, and were investigated by a self-designed questionnaire on lifestyle then structural equation model of factors related to lifestyle for patients with NAFLD was built. ResuIts The model fitted well. As the model indicted, the factors exerting direct effects on the NAFLD included body mass index （BMI）, poor dietary habit, good dietary habit and smoking and the effect values were-0.45,-0.16, 0.19, -0.09 respectively. Indirect effect between behavioral pattern and the NAFLD existed, and the BMI was the mediator between them. ConcIusion BMI, dietary habit and smoking exert influence on NAFLD directly and behavioral pattern impact NAFLD indirectly under the effect of mediating by BMI. It is necessary to control weight by changing behavioral pattern, adjust the diet structure and quit smoke in order to control the NAFLD.
