PURPOSE
The purpose of this study was to elucidate whether body mass index (BMI), activity level, and other risk factors predispose patients to Achilles tendon ruptures.
MATERIALS AND METHODS
A retrospective review of 279 subjects was performed (93 with Achilles tendon rupture, matched 1:2 with 186 age/sex matched controls with ankle sprains). Demographic variables and risk factors for rupture were tabulated and compared.
RESULTS
The rupture group mean BMI was 27.77 (95% CI, 26.94-28.49), and the control group mean BMI was 26.66 (95% CI, 26.06-27.27). These populations were found to be statistically equivalent (p=0.047 and p<0.001 by two one-sided t-test). A significantly higher proportion of those suffering ruptures reported regular athletic activity at baseline (74%) versus controls (59%, p=0.013).
CONCLUSION
There was no clinically significant difference found in BMI between patients with ruptures and controls. Furthermore, it was found that patients who sustained ruptures were also more likely to be active at baseline than their ankle sprain counterparts.
目的
本研究旨在阐明体重指数（BMI）、活动水平及其他风险因素是否会使患者易患跟腱断裂。
材料与方法
对279名受试者进行回顾性研究（93例跟腱断裂患者，按1:2比例与186例年龄/性别匹配的踝关节扭伤对照者配对）。将人口统计学变量和断裂风险因素制成表格并进行比较。
结果
断裂组的平均BMI为27.77（95%可信区间，26.94 - 28.49），对照组的平均BMI为26.66（95%可信区间，26.06 - 27.27）。通过双侧单侧t检验发现这两组人群在统计学上无差异（p = 0.047且p < 0.001）。与对照组（59%，p = 0.013）相比，断裂患者中在基线时报告有规律体育活动的比例显著更高（74%）。
结论
断裂患者与对照组在BMI方面未发现具有临床意义的差异。此外，还发现跟腱断裂患者在基线时比踝关节扭伤患者更可能处于活动状态。
