背景：组织监测系统 (TMS) 是一种通过一系列日常体重测量来估计身体组织变化的算法。它的目的是为人们提供组织重量变化的反馈，以便他们可以有一个基础来估计需要改变多少摄入量或支出才能将体重维持在规定水平。我们测试了 TMS 在防止新生大学第一学期体重增加方面的有效性。 方法：在两项类似但独立的研究（2002 年秋季和 2003 年）中，女大学生获得了模拟浴室秤，并被要求每天早上起床后立即称重，然后将体重通过电子邮件发送给我们的工作人员。 7 天后，对每个参与者最近 7 天的体重日函数执行线性函数。在第一项研究中，该函数的斜率通过电子邮件发送回参与者。在第二项研究中，使用线性回归技术确定了最后一点与原始体重之间的差异，并将其转换为卡路里，并将信息通过电子邮件发送回参与者。两项研究中的对照组参与者在学期开始和结束时均进行了称重。结果：未经治疗的对照组分别增加了 3.1 +/- 0.51 kg 和 2.0 +/- 0.65 kg（两项研究的 P < 0.01），而实验组的体重增加为 0.1 +/- 0.99 kg 和 -0.82 +/- 0.56 kg，这些值与零没有显着差异。结论：TMS这似乎是帮助女大学新生在有利于体重增加的环境中抵抗体重增加的有效技术。这些结果表明，TMS 可能是一种有用的方法，有助于抑制超重和肥胖患病率的缓慢增长，这是所有工业化社会的特征。
Background: The Tissue Monitoring System (TMS) is an algorithm that estimates changes in body tissue from a series of daily weight measures. It is intended to provide people with a feedback of changes in their tissue weight so they may have a basis for estimating how much they would have to change their intake or expenditure to maintain their weight at a prescribed level. We tested the effectiveness of the TMS to prevent freshmen from gaining weight during their first semester in college.Methods: In two similar but independent studies (Fall 2002, 2003), female freshmen college students were given analog bathroom scales and instructed to weigh themselves each morning immediately after rising from bed, then e-mail their weight to our staff. After 7 days, a linear function was performed on the most recent 7 days of the weight-day function for each participant. In the first study, the slope of this function was e-mailed back to the participants. In the second study, the difference between last point and the original weight was determined, using linear regression techniques, converted to calories, and the information was e-mailed back to the participants. Control participants in both studies were weighed at the beginning and the end of the semester.Results: The untreated controls gained 3.1 +/- 0.51 kg and 2.0 +/- 0.65 kg, respectively (P < 0.01 for both studies), whereas weight gain of the experimental groups was 0.1 +/- 0.99 kg and -0.82 +/- 0.56 kg, values that were not significantly different than zero.Conclusions: The TMS appears to be an effective technique to help female college freshmen resist gaining weight in an environment that is conducive to weight gain. These results suggest that the TMS may be a useful method to help curb the slow increase in the prevalence of overweight and obesity that is characteristic of all industrialized societies.
