利用生物电阻抗法对进藏工作汉族男性成年人群与西藏藏族男性成年人群脂肪含量进行比较分析
Comparative analysis of the fat distribution characteristics of Han males adults worked in Tibet with Tibet males adults in Tibet by using bioelectrical impedance analysis method
目的 运用生物电阻抗分析法，通过测量得出进藏工作汉族男性成年人群与西藏藏族男性成年人群脂肪含量的数值，并对两者进行对比分析，进而探讨进藏工作汉族男性成年人群与西藏藏族男性成年人群脂肪含量及分布的不同。 方法 在知情同意的情况下，整体随机抽取进藏工作汉族男性与西藏藏族男性健康成人作为研究对象，共选取337人(汉族男性为164例，藏族男性为173例)，应用体成分分析仪,对所有受试者进行检测，得出脂肪总量、左上肢（左下肢、右上肢、右下肢、躯干）脂肪量，进而推算出体脂肪率、左上肢（左下肢、右上肢、右下肢、躯干）脂肪率。所有结果输入SPSS19.0统计软件包，进行独立样本t检验和方差分析统计学处理。 结果 进藏工作汉族男性成年人群的各项脂肪含量数值均小于西藏藏族男性成年人群，而且差异具有显著性（P＜0.01或P＜0.05）。进藏工作汉族男性成年人群与西藏藏族男性成年人群的脂肪含量随年龄变化的趋势基本一致，各部位的脂肪含量和脂肪率均随年龄增加而增大。脂肪量的增加均在30岁年龄组到40岁年龄组增加明显，此后体脂含量增加减慢，甚至50岁年龄组的汉族人群的下肢脂肪含量出现了轻度下降。结论 整体上，进藏工作汉族男性成年人群的各项脂肪含量数值均小于西藏藏族男性成年人群。进藏工作汉族男性成年人群和西藏藏族男性成年人群脂肪含量随年龄的增长发生变化，总体呈上升趋势，但不同部位的脂肪变化趋势略有不同。
Objective To measure the body fat content of Han adults males worked in Tibet and Tibet males in Tibet by Bioelectrical Impedance Analysis method, and to compare the two groups’ values to discuss the fat distribution feature and regularity of two groups. Methods A total of 337 Han adults males worked in Tibet and Tibet males in Tibet (Han male for 164 cases, Tibet male for 173 cases) were randomly selected and the selected subjects had sighed the informed consent as the research object. The subjects were detected by the body composition analyzer which concluded the total fat, left upper limbs (left lower limbs, right upper limbs, right lower limbs, trunk) fat content, the body adipose rate, and left upper limbs (left lower limbs, right upper limbs, right lower limbs, trunk)fat ratio.The results were inputted in SPSS19.0, a statistical software package, and processed by independent sample t test and variance analysis. Results The fat contents(total,limbs and trunk) of Han male adults were lower than Tibet male adults(P<0.01 or P＜0.05). The total fat and each part fat content in two groups were increased with age, appeared two peaks, one in 30 years old age group and another in 40 years old age group. After the peak the fat content curve was flat and even decreased of lower limb fat content in 50 years old and above age group of Han male adults. Conclusion The fat contents(total,limbs and trunk) of Han male adults are lower than Tibet male adults. The fat contents of two groups(Han and Tibet) change with the growth of the age, and the general fat content is rising, but the change trend of the fat in different parts is different.
