目的探讨藏族青少年生长发育特点及建立身高与相关因素模型,为预测藏族个体的生长发育状况和采取有效措施进行健康干预提供科学依据。方法分层整群抽取西藏拉萨和那曲2个地区5所中学和3所小学的942名藏族青少年,对体质发育指标进行测量,对体重、坐高、足高、手长与身高进行相关和回归分析,建立最优拟合优度的回归模型。结果藏族青少年不同性别、不同年龄组间体重、坐高、足高、手长、身高差异有统计学意义;不同性别、不同年龄组人群体重、坐高、手长分别与身高呈显著线性相关,部分年龄组足高与身高显著相关;不同性别、不同年龄建立的身高与坐高、足高、手长多元回归模型有显著意义。结论藏族青少年生长发育状况存在性别差异,用体重、坐高、足高、手长预测身高具有可行性。
Objective To explore the characteristics of Tibetan adolescent growth and development and to establish a model of height and related factors to provide a scientific basis for predicting the growth and development status of Tibetans and taking effective measures for health intervention. Methods A total of 942 Tibetan adolescents from 5 secondary schools and 3 primary schools in Lhasa, Tibet and two primary schools in Lhasa, Tibet were stratified and clustered to measure the physical development indicators. The correlations between weight, height, height, hand length and height were obtained Analysis, the establishment of the optimal goodness of fit of the regression model. Results There were significant differences in body weight, height, height, hand length and height between different age groups and different gender groups. There was a significant linear correlation between body weight, sitting height and hand length in different gender and age group, In some age groups, height and height were significantly related to height and height, height and hand length of multiple gender and age were significant. Conclusion There are gender differences in the growth and development status of Tibetan adolescents. It is feasible to predict the height of the adolescent with height, weight, height and hand length.
