摘要
目的：探讨在不同海拔的高原环境下，拉萨与那曲地区藏族青少年血清钙（Ca）和无机磷（P）的特点及其差异。方法：采用分层整群抽样的方法，选取拉萨和那曲地区的12～18岁健康藏族青少年共1458人，测定身高及血清钙（偶氮胂Ⅲ法）、无机磷（磷钼酸比色法）的含量。结果：①拉萨藏族青少年血清钙为（2．86±0．17）mmol／L，磷为（1.61±0．29）mmol／L，其水平均显著高于那曲地区（P〈O．01），即血清钙为（2．24±0．18）mmol／L，磷为（1.31±0．20）mmol／L；②两个地区血清Ca无年龄差异（P〉0．05），血清P与[Ca]·[P]随年龄增长水平降低（P〈0．05），那曲男性在16岁以后，女性在17岁以后，[Ca]·[P]低于2．82；③血清[Ca]·[P]水平均与身高密切相关（P〈0．01）。结论：拉萨与那曲地区藏族青少年血清钙比较稳定，无机磷水平与年龄显著相关，两个海拔地区其规律有一定的差异。
To study the characteristics and differences of serum total calcium（Ca） and inorganic phosphate（P）levels in Tibetan adolescents living on Lhasa and Naqu. Methods： 1458 healthy Tibetan adolescents in Lhasa and Naqu aged 12～18 years were selected in the study, their height and the levels of Ca and P were tested. Results： The Ca levels of I.hasa adolescents were （2. 86±0. 17）mmol/L , and P levels were （1.61±0. 29）mmol/L. The Ca and P levels of Lhasa adolescents were significanty higher than those Naqu adolescents（P〈0. 01）mCa： （2. 24±0. 18）mmol/L,P： （1.31±0. 20）mmol/L]. In both areas, no affec- tion was found for serum Ca by age factor, but the levels of P declined with age（P〈0. 05）. [Ca]·[P] were lower 2. 82of boys after 16 and girls after 17 years in Naqu. Positive correlativity was observed [Ca]·[P] with height（r=-0.25,-0.35,P〈0. 01）. Conclusion： Serum Ca were not affected by age in Tibetan adolescent in Lhasa and Naqu, but P are closely associated with age, in both areas, the change of serumCa and P were difference.
