目的分析腹部B型超声脂肪肝声像阳性（脂肪肝）体检人群人体成分、血脂水平变化，比较不同内脏脂肪面积体检者的脂肪肝检出率，并探讨体检人群人体成分分析与血脂检测的临床意义。方法将230名自愿进行人体成分测定的体检者（均行腹部B型超声检测）作为研究对象，其中脂肪肝患者83人（脂肪肝组），非脂肪肝患者（腹部B型超声脂肪肝声像阴性）147人（非脂肪肝组）。对比两组研究对象的人体成分、血脂水平，并比较不同内脏脂肪面积研究对象的脂肪肝检出率。结果脂肪肝组内脏脂肪面积、体重、体质量指数、腰臀比、肌肉量、去脂体重、骨骼肌重量、体脂肪重量、体脂百分比、四肢脂肪重量、躯干脂肪重量、腰围均较非脂肪肝组大或高，总胆固醇、甘油三酯、低密度脂蛋白胆固醇、载脂蛋白B水平均较非脂肪肝组高，高密度脂蛋白胆固醇、载脂蛋白AI水平、载脂蛋白AI/载脂蛋白B均较非脂肪肝组低，差异均有统计学意义（均P＜0.05）。内脏脂肪面积＜80 cm2、80～100 cm2和≥100 cm2三组研究对象，其脂肪肝的检出率分别为21.32%（29/136）、58.82%（20/34）、56.67%（34/60），差异有统计学意义（χ2=31.490，P＜0.001）。结论有脂肪肝的体检人群人体成分和血脂水平与无脂肪肝的体检人群有差异。对人体成分和血脂水平的异常者提出警告，改变其饮食结构和生活习惯，或可预防脂肪肝的发生。

ObjectiveTo analyze the changes in body composition and blood lipids levels of the abdominal B-mode ultrasound fatty liver sonogram-positive (fatty liver) physical examination population, compare the detection rate of fatty liver in physical examinees with different visceral fat areas, and explore the clinical significance of body composition analysis and blood lipids detection in the physical examination population. MethodsA total of 230 physical examinees who voluntarily underwent body composition measurement (all underwent abdominal B-mode ultrasound) were selected as research subjects, including 83 fatty liver patients (fatty liver group) and 147 people without fatty liver (abdominal B-mode ultrasound fatty liver sonogram-negative) (non-fatty liver group). The body composition and blood lipids levels were compared between the two groups, and the detection rate of fatty liver between research subjects with different visceral fat areas was compared. ResultsThe visceral fat area, body weight, body mass index, waist-hip ratio, muscle mass, lean body mass, skeletal muscle weight, body fat weight, body fat percentage, limb fat weight, trunk fat weight, and waist circumference in the fatty liver group were larger or higher than those in the non-fatty liver group, the levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol, and apolipoprotein B were higher than those in the non-fatty liver group, and the levels of high-density lipoprotein cholesterol, apolipoprotein AI, and apolipoprotein AI/apolipoprotein B were lower than those in the non-fatty liver group， with statistically significant differences (all P＜0.05). The detection rates of fatty liver in the three groups (visceral fat area <80 cm2, visceral fat area 80~100 cm2, and visceral fat area≥100 cm2) were 21.32% (29/136), 58.82% (20/34), and 56.67% (34/60), respectively, with statistically significant difference (χ2=31.490, P＜0.001). ConclusionThe body composition and blood lipids levels of the physical examination population with fatty liver are different from those of the physical examination population without fatty liver. Warning people with abnormal body composition and blood lipids levels and changing their diet and lifestyle habits may prevent the occurrence of fatty liver.
