College students' physical fitness is likely to be directly related to their cells' health. However, there is a lack of literature on whether the relationship between cell health and college students' physical fitness is direct or indirect. This study used a structural equation modeling (SEM) approach to investigate the connection between cell health and college students' physical fitness.
This cross-sectional study collected data from 838 volunteers (502 males and 336 females, average age of 18.74 ± 1.5 years) who were college students from the Shandong province of China in July 2023. Initially, we obtained anthropometric measurements and conducted physical fitness tests on the students. Then, we performed Pearson correlation analysis and principal component analysis to screen variables and explore potentially influencing factors. Finally, we examined associations between the variables and determined whether there were direct or indirect influences among factors using SEM.
The results revealed a significant correlation between the cell health factor and the muscle strength factor (path coefficient = 0.97; p < 0.001) as well as the fat obesity factor (path coefficient = -0.52; p < 0.001). The cardiovascular factor exhibited a weak correlation with the cell health factor (path coefficient = 0.11; p < 0.01). Moreover, the cardiovascular factor acted as a mediating variable between the muscle strength factor and the cell health factor, with a positive correlation observed between the muscle strength factor and the cell health factor (path coefficient = 0.40; p < 0.001).
These findings suggest that cell health is indicative of muscle strength and cardiorespiratory fitness. Our findings demonstrate that assessing the cell health of college students can be a valuable method for evaluating their overall health.
大学生的体质健康可能与细胞健康直接相关。然而，关于细胞健康与大学生体质健康之间的关系是直接的还是间接的，相关文献却很少。本研究采用结构方程模型（SEM）方法来探讨细胞健康与大学生体质健康之间的关系。
本横断面研究于 2023 年 7 月从中国山东省的大学生中招募了 838 名志愿者（男生 502 名，女生 336 名，平均年龄 18.74±1.5 岁）。首先，我们对学生进行了人体测量和体质测试。然后，我们进行了 Pearson 相关分析和主成分分析，以筛选变量并探索潜在的影响因素。最后，我们检查了变量之间的关联，并使用 SEM 确定因素之间是否存在直接或间接影响。
研究结果表明，细胞健康因子与肌肉力量因子（路径系数=0.97；p<0.001）和脂肪肥胖因子（路径系数=-0.52；p<0.001）之间存在显著相关性。心血管因子与细胞健康因子呈弱相关（路径系数=0.11；p<0.01）。此外，心血管因子在肌肉力量因子和细胞健康因子之间充当中介变量，肌肉力量因子与细胞健康因子之间存在正相关（路径系数=0.40；p<0.001）。
这些发现表明细胞健康与肌肉力量和心肺功能有关。我们的研究结果表明，评估大学生的细胞健康状况可以成为评估其整体健康状况的一种有价值的方法。
