【摘要】：目的研究运用双能X线吸收测量法(DEXA)测量肥胖症患者减肥效果,为减肥治疗提供科学客观的评价指标。方法选取2014年8月~2015年6月佛山市中医院就诊的80例单纯性肥胖症患者为研究对象,按照性别不同,将患者分为男性组(45例)和女性组(35例)。分别采用DEXA对两组患者减肥治疗前后进行全身组织成分含量测定,包括体内脂肪含量(BF%)、脂肪量指数(FMI)及腹部内脏脂肪量面积(VAT);检测比较两组治疗前后体重指数(BMI)、低密度脂蛋白-胆固醇(LDL-C)、三酰甘油(TG)、总胆固醇(TC)情况;分析BF%、FMI、VAT与BMI及LDL-C、TG、TC的变化量与VAT的相关性。结果两组患者治疗后的BF%、FMI、VAT及BMI均较治疗前明显降低(P0.05或P0.01),且变动方向与BMI相一致;治疗前后两组患者的BF%、FMI、VAT均与BMI呈显著正相关(P0.01);治疗后两组患者的LDL-C、TG、TC与治疗前比较,均明显降低(P0.05或P0.01),且两组LDL-C、TG、TC的变化量与VAT的变化量均呈显著正相关(P0.01)。结论 DEXA法测定的指标与BMI的评价一致性较好,可作为监测肥胖症减肥效果的评价指标,尤其是VAT。
[Abstract]:Objective to study the effect of dual energy X-ray absorptiometry (DEXA) on obesity patients. Methods Eighty patients with simple obesity from August 2014 to June 2015 were divided into male group (45 cases) and female group (35 cases). DEXA was used to measure the content of body tissue components before and after treatment of weight loss in the two groups. Body fat content (BF%), fat volume index (FMI) and abdominal visceral fat area (VAT);) were measured before and after treatment. Body mass index (BMI),) low density lipoprotein cholesterol (LDL-C) and triglyceride (TG), total cholesterol (TC) were compared before and after treatment. The correlation between BF%,FMI,VAT, BMI, LDL-C,TG,TC and VAT was analyzed. Results after treatment, the BF%,FMI,VAT and BMI of the two groups were significantly lower than those before treatment (P0.05 or P0.01), and the direction of change was the same as that of BMI, the BF%,FMI,VAT of the two groups was positively correlated with BMI before and after treatment (P0.01), and the LDL-C,TG,TC of the two groups was significantly higher than that of the patients before and after treatment (P0.01). All of them were significantly decreased (P0.05 or P0.01), and the changes of LDL-C,TG,TC in both groups were positively correlated with the changes of VAT (P0.01). Conclusion the index measured by DEXA method is in good agreement with the evaluation of BMI, and can be used as an index to evaluate the effect of obesity, especially VAT..
