【摘要】：目的了解西藏拉萨市藏族儿童青少年体成分现状，探讨拉萨市藏族儿童青少年体成分的年龄变化趋势及性别差异，为科学评价拉萨市藏族儿童青少年群体的体质状况、合理指导其生活方式、寻找与体成分相关疾病的危险因素等提供重要的参考依据。方法在知情同意的情况下，随机整群抽取拉萨市藏族7-19岁健康儿童青少年作为研究对象，其父母均为藏族，3代无族外通婚，共选取1360人(男为654例，女为706例)，应用人体成分分析仪,对所有受试者进行测量，测量项目有：身高、体重、身体总脂肪量、上肢脂肪量、下肢脂肪量、躯干脂肪量、身体总肌肉量、上肢肌肉量、下肢肌肉量、躯干肌肉量、身体水分含量、蛋白质含量、推定骨含量。将所有结果输入SPSS13.0软件包，进行描述性统计分析、方差分析和独立样本t检验等统计学处理。结果西藏拉萨市藏族儿童青少年的身高、体重、去脂体重、上肢脂肪量、下肢脂肪量、躯干脂肪量、脂肪总量、上肢脂肪率、下肢脂肪率、躯干脂肪率、体脂肪率、上肢肌肉量、下肢肌肉量、躯干肌肉量、肌肉总量、身体水分、蛋白质含量和推定骨含量等18项指标均有性别间差异（P＜0.05）。其中上肢脂肪量、下肢脂肪量、躯干脂肪量和脂肪总量4项衡量脂肪含量的指标，在7-8岁时男女生差异不明显（P＞0.05），8岁以后均显示女生大于男生（P＜0.01）；其余10项指标除骨含量外均表现为男生大于或等于女生；7-10岁时男女生骨含量相等，11-12岁时女生骨含量大于男生（P＜0.05），13-19岁时男生大于女生（P＜0.01）。通过对拉萨市藏族与北京市、潍坊市汉族儿童青少年体成分的比较发现，拉萨市藏族男生的脂肪总量和体脂率明显小于北京市和潍坊市汉族男生（P＜0.01），比较女生各项，差异无显著性意义（P＞0.05）。结论 1.西藏藏族儿童青少年在所测各项指标中，各年龄组除脂肪含量及11岁-12岁年龄段的骨含量男生低于女生外，其他各项指标男生都高于或等于女生。 2.西藏藏族儿童青少年体成分随年龄的增长发生变化，，尤其在12岁-13岁以后的各年龄组变化显著。 3.西藏藏族儿童青少年与其他地区及民族的体成分有一定差异。
[Abstract]:Purpose. To understand the present situation of body composition of Tibetan children and adolescents in Lhasa, Tibet, and to explore the trend of age change and gender difference of body composition of Tibetan children and adolescents in Lhasa, so as to scientifically evaluate the physical condition of Tibetan children and adolescents in Lhasa. Reasonable guidance of their lifestyle and search for risk factors of diseases related to body composition provide important reference basis. Method. In the case of informed consent, random cluster sampling of healthy Tibetan children aged 7-19 years in Lhasa was carried out. Their parents were all Tibetan children who had 3 generations of non-ethnic intermarriage. A total of 1360 persons (654 males) were selected. A total of 706 female patients were measured by body composition analyzer. The measurements included height, weight, total body fat, upper limb fat, lower extremity fat, trunk fat, total body muscle volume, upper limb muscle volume, and total body weight. Lower extremity muscle volume, trunk muscle volume, body water content, protein content, bone content. All the results were input into SPSS13.0 software package for descriptive statistical analysis, variance analysis and independent sample t-test. Results. Height, weight, body fat, upper limb fat, lower extremity fat, trunk fat, total fat, upper limb fat, lower extremity fat rate, trunk fat rate, body fat rate, body fat rate, upper limb muscle mass of Tibetan children and adolescents in Lhasa, Tibet, There were gender differences in muscle volume, trunk muscle volume, total muscle volume, body moisture, protein content and presumed bone content among the 18 indexes (P < 0.05). Four measures of fat content in the trunk and the total amount of fat, The difference between male and female students at 7-8 years old was not obvious (P > 0.05) after 8 years old, the female students were larger than male students (P < 0.01), the other 10 indexes except bone content showed that the male and female students had the same bone content at 7-10 years old and the female students had higher bone content at the age of 11-12 years. At the age of 13-19, boys were larger than girls (P < 0.01). Comparing the body composition of Han children and adolescents in Weifang, it was found that the total fat content and body fat rate of Tibetan boys in Lhasa city were significantly lower than those in Beijing and Weifang Han nationality boys (P < 0.01), but there was no significant difference between female students and girls (P > 0.05). Conclusion. 1. Among the indexes measured by Tibetan children and adolescents in Tibet, except fat content and bone content of 11 ~ 12 years old boys were lower than girls, all other indexes were higher or equal to girls. 2. The body composition of Tibetan children and adolescents in Tibet changed with the increase of age, especially after 12 ~ 13 years old. 3. The physical composition of Tibetan children and adolescents in Tibet is different from that of other regions and ethnic groups.
