基于人体成分分析探索膏人脂人肉人的辅助判别标准

目的:探索下肢脂肪量对膏人、脂人、肉人的辅助判别价值。方法:采用横断面人群流行病学调查方法对纳入样本进行统计学研究,以下肢脂肪量作为基本研究指标,采用受试者操作特征(ROC)曲线、约登指数等统计方法进行分析,并计算各指标的敏感度和特异性。结果:采用右侧下肢脂肪量辅助诊断脂人、膏人、肉人的界值分别是2.05,2.25和3.05,据此将右侧下肢脂肪量分为由小到大的4个区间,分别对应脂人、众人、膏人、肉人。采用该方法诊断膏人、脂人、肉人的灵敏度均在67%以上,特异性均在74%以上,诊断效率在72%以上;确诊率从37.4%提高到83.1%。结论:采用下肢脂肪量辅助诊断"膏脂肉人"与望诊结果具有高度一致性,可以较好地对难以得出定性诊断结果的人群实现进一步确诊。

Analysis on Auxiliary Criterion of Gaoren,Zhiren,Rouren Based on Body Composition

Objective:To explore the auxiliary discriminative value of fat mass of lower extremities to Gaoren,Zhiren and Rouren. Methods:The cross-sectional population epidemiological survey method was used to conduct statistical research on the included samples. The fat mass of lower extremities was used as the basic research index,and the statistical methods such as ROC curve and Yoden index were used to analyze and calculate the sensitivity and specificity of each index. Results:The boundary values of the fat mass of right lower extremity to assist in the diagnosis of Zhiren,Gaoren and Rouren were 2.05,2.25,and 3.05,respectively. According to this,the fat mass of the right lower extremity was divided into four sections ranging from small to large,corresponding to Zhiren,ordinary people,Gaoren,Rouren. The sensitivity of the method for the diagnosis of Gaoren,Zhiren and Rouren was above 67%,the specificity was above 74%,the diagnostic efficiency was above 72%;the diagnosis rate increasing from 37.4% to 83.1%. Conclusion:The use of fat mass of lower extremities to assist in the diagnosis of "Gaoren,Zhiren and Rouren" is highly consistent with the results of the inspection,which can better confirm the diagnosis of people who are difficult to obtain qualitative diagnosis results.
