身体机能指标对体质的影响及地理分布规律研究

Influence of Body Function Index to Constitution and Geographical Distribution

目的：通过分析比较不同区域的人体机能指标变化差异，找出区域分布规律，为进一步完善体质指标评价体系提供参考依据。方法：以我国20-69岁的成年人为研究对象，采用分层整群抽样的方法，主要收集肺活量、台阶指数数据，采用Kriging等多元统计方法分析资料。结果：安静脉搏（OR=0.89，95%CI为0.86-0.92）、收缩压（0.93，0.89-0.96）、舒张压（0.81，0.78-0.84）、台阶指数（2.21，2.13-2.29）、肺活量（5.54，5.32-5.77）是影响体质达标与否的相关因素；全国范围内成年人肺活量与台阶指数均呈现片状或板块状分布，不同地区存在明显的地理分布差异，并显示出一定的变化趋势及规律。结论：肺活量与台阶指数是影响身体体质水平的两个最重要的指标之一；肺活量、台阶指数两项指标均与海拔高度有关联。

Objective： Based on the analysis comparison of different parts of the human body function index differences, find out the regional distribution, provide a reference basis for further perfecting the evaluation system of physique indicators. Methods： With 20 --69 adults of China as the research object, using the stratified cluster sampling method to collect vital capacity and step index data and using Kriging method to analyze the data. Results： The results of Logistic regression analysis showed that major risk factors influencing fitness were quiet pulse（OR=0. 89, 95%CI： 0. 86-0. 92）, systolic pressure （0. 93,0. 89-0. 96）, diastolic pressure（0. 81,0. 78-0. 84）, step index （2. 21,2. 13-2. 29）, vital capacity （5.54,5.32-5.77）. Adults nationwide vital capacity and step index sheet or plate shape distribution, there are obvious geographical distribution differences in different areas, and shows a certain tendency and rule. The vital capacity and step index of the adults in the whole country presented a patchy or plate distribution. There were obvious geographical distribution differences in different regions, and showed a certain change trend and law. Conclusion： Vital capacity and step index is affecting one of the two most important indexes of the body physique level; Vital capacity and step index both associated with the altitude.
