An investigation on the relationship between BMD and BMI of Tibetan college students in plateau -- A case study of Tibet University
高原藏族大学生BMD与BMI关系的调查研究——以西藏大学为例

摘要

本研究旨在探讨高原地区藏族大学生的骨密度（BMD）与体重指数（BMI）之间的关系。通过采用定量研究方法，对西藏大学的藏族学生进行问卷调查和身体检查，收集了他们的BMD和BMI数据。通过随机抽样选取了305名来自西藏大学的藏族学生作为样本，对他们进行了BMD和BMI的测量。分析结果显示，这些学生的骨密度Z值在性别上有明显差异，同时，不同BMI分组间的骨密度Z值也表现出显著的差异性。由此可知，高原藏族女性学生比高原藏族男性学生更可能患骨质疏松症，而体重超标及肥胖的高原藏族学生相较于体重正常，其患骨质疏松症的风险更高。

Abstract

This study aims to explore the relationship between bone mineral density (BMD) and body mass index (BMI) among Tibetan college students in high-altitude areas. By using the quantitative research method, we conducted a questionnaire survey and physical examination on Tibetan students in Xizang University, and collected their BMD and BMI data. Through random sampling, 305 Tibetan students from Xizang University were selected as samples, and their BMD and BMI were measured. The analysis results show that there are significant gender differences in the Z-values of bone density among these students, and there are also significant differences in the Z-values of bone density between different BMI groups. From this, it can be inferred that Tibetan female students in the plateau are more likely to suffer from osteoporosis than Tibetan male students, and Tibetan students who are overweight or obese have a higher risk of osteoporosis compared to those with normal weight.
