成人脂肪肝与体重指数和血脂水平的关系分析

目的探讨成人脂肪肝与体重指数、血脂水平之间的关系,为社区防治脂肪肝提供依据。方法对平谷区滨河街道社区居民782人用超声诊断法、血脂检测法及体重指数法诊断脂肪肝、血脂水平和肥胖,并分析脂肪肝与体重指数、血脂的关系。结果筛查出脂肪肝人数368例,占47.06%(368/782),肥胖人数512例,占65.47%(512/782)。肥胖同时伴脂肪肝人数332例,占肥胖人数64.84%(332/512),脂肪肝患者中血脂异常274例,占74.46%(274/368)。脂肪肝患者体重指数(BMl)、血脂水平(TC、TG、LDL-C、HDL-C)与非肥胖无脂肪肝患者比较,差异有统计学意义(P0.05);肥胖伴脂肪肝患者与非肥胖伴脂肪肝患者血脂水平比较,差异无统计学意义(P0.05);脂肪肝患者血脂增高类型是以混合型高脂血症、高TG血症为主与非脂肪肝患者的比较差异有统计学意义(P0.05)。结论健康人群脂肪肝患病率高,脂肪肝与体重指数增大、高脂血症(尤其是混合型高脂血症,高TG血症)有高度相关。

Relationship between BMI, Blood Lipid Level and Fatty Liver in Adults

Objective ] To explore the relationship between body mass index （ BMI ）, blood lipid level and fatty liver in adults, provide the reference for prevention and control of fatty liver in community. Methods]The fatty liver, blood lipid level and obesity were respectively diagnosed by ultrasonography, blood lipid detection and BMI method among 782 residents in Binhe community of Pinggn district. The relationship between BMI, blood lipid level and fatty liver was analyzed. Results] There were 368 （47.06%） cases of fatty liver, and 512 （65.47% ） cases of obesity. There were 332 cases of obesity complicated with fatty liver, which accounted for 64.84% （ 332/512 ） of obesity cases. Among 368 patients with fatty liver, there were 274 74.46% ） cases of lipid abnormality. There were significant differences in （BMI） and blood lipid level （TC, TG, LDL-C, HDL-C） between patients with fatty liver and people without obesity and fatty liver （ P 〈 0.05 ）. There was no significant difference in blood lipid level between patients with obe- sity complicated with fatty liver and people without obesity and fatty liver. The types of hyperlipidemia among patients with fatty liver were mainly combined hyperlipidemia and hypertriglyceridemia, and compared with the patients without fatty liver, the difference was significant （ P 〈 0.05 ）. Conclusion] The prevalence of fatty liver was high in healthy population, and there was a high correlation between fatty liver and BMI increase, hyperlipidemia （ especially combined hyperlipidemia and hypertriglyceridemia）.
