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(P<0.05);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(P>0.05);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(P<0.05)。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。
Objective To explore the relationship between adult fatty liver and body mass index and blood lipid levels and to provide basis for community prevention and treatment of fatty liver. Methods 782 community residents of Binhe Street in Pinggu District were diagnosed fatty liver, lipids and obesity by ultrasonic diagnosis, blood lipid test and body mass index method. The relationship between fatty liver and body mass index and blood lipid was analyzed. Results The number of fatty liver was 368 (47.06% (368/782)) and obesity was 512 (65.47% (512/782)). There were 332 cases of obesity accompanied with fatty liver, accounting for 64.84% (332/512) of the obese patients. There were 274 cases (74.46%) of the patients with fatty liver disease (274/368) with dyslipidemia. The difference of body mass index (BMl), blood lipid level (TC, TG, LDL-C, HDL-C) in patients with fatty liver was statistically significant compared with those in non-obese patients without fatty liver (P <0.05) Compared with non-obese patients with fatty liver, there was no significant difference in the level of serum lipids (P> 0.05). The type of hyperlipidemia in patients with fatty liver was mainly based on mixed hyperlipidemia and hypercholesteremia with non-fatty liver There was statistical significance (P <0.05). Conclusion The prevalence of fatty liver in healthy population is high. Fatty liver is associated with increased body mass index and hyperlipidemia (especially mixed hyperlipidemia and hypercholesterolemia).
