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 estimate the fat content of male adult population in Tibet and Tibetan male population in adult population in Tibet by bioelectrical impedance analysis and compare the two data to explore the relationship between male adult population in Tibet and Tibetans Male adult population fat content and distribution of different. Methods A total of 337 Han Chinese male Tibetan males and Tibetan healthy male Tibetan males were randomly selected from the Han population in Tibet as a whole with informed consent. A total of 337 males (164 Han males and 173 Tibetan males) were selected. Body composition analyzer, The total amount of fat, the amount of fat in the left upper extremity (left lower extremity, right upper extremity, right lower extremity, trunk) were calculated and the body fat percentage was calculated. The left upper extremity (left lower extremity, right upper extremity, Trunk) fat rate. All results were entered into the SPSS19.0 statistical package and subjected to independent sample t-test and analysis of variance (ANOVA). Results The fat content of male adult population in working Han nationality in Tibet was lower than that of Tibetan male adult population in Tibet, and the difference was significant (P <0.01 or P <0.05). The fat content of Han male adult population in Tibetan work and Tibetan male adult population in Tibet basically accord with the trend of age. The fat content and fat percentage of all parts increased with age. Fat mass increased significantly in the 30-year-old group to the 40-year-old group, and thereafter body fat content increased slowly, even in the 50-year-old Han population showed a slight decrease in lower limb fat content. Conclusion On the whole, the values of fat content of male adult population in Tibet who work in Tibet are less than that of Tibetan male adult population in Tibet. The fat content of Han male adult population and Tibetan Tibetan male adult population who moved into Tibet changed generally with increasing age, but there was a slight difference in the trend of fat change in different sites.
