Abstract

National guidelines recommend that waist circumference (WC) be measured in patients with a body mass index (BMI) 27–35 kg/m2. Unfortunately, perhaps due to logistical reasons, WC is seldom measured in clinical settings. Herein, we describe the performance of a self-operated waist measurement device (SOWMD) as a potential means to overcome barriers to measuring WC.Ten volunteers underwent WC measures by professionals and SOWMD on 5 separate days to assess the reproducibility and accuracy. We then compared SOWMD measures with CT-derived fat content by recruiting 81 patients scheduled for a diagnostic abdominal CT scan.There was no difference between professionally measured and SOWMD-measured WC; the intraindividual coefficient of variation over the 5 days was between 0.4% and 2.2%. The WC measured manually, by SOWMD and CT scan were highly correlated (r=0.90–0.92, all p<0.001). The minimal WC measured by SOWMD was a better predictor (r=0.81 for all patients, r=0.87 for men, both p<0.001) of CT-measured visceral adipose tissue volume than other approaches. The minimal WC measured by SOWMD was correlated with fasting plasma glucose (r=0.40, p<0.05), triglyceride (r=0.41, p<0.01) and high-density cholesterol (r=−0.49, p<0.001) concentrations.SOWMD is a reproducible, accurate and convenient way to measure WC that can provide added value for health care providers when combined with BMI information.
自动腰围测量装置的描述和评估
国家指南建议,体重指数(BMI)为 27-35 kg/m2 的患者应测量腰围(WC)。遗憾的是,也许是由于后勤方面的原因,临床上很少测量腰围。在此,我们介绍了自操作腰围测量装置(SOWMD)的性能,它是克服测量腰围障碍的一种潜在手段。10 名志愿者分别在 5 天内接受了专业人员和 SOWMD 的腰围测量,以评估其重现性和准确性。然后,我们招募了 81 名计划接受腹部 CT 扫描诊断的患者,将 SOWMD 测量值与 CT 导出的脂肪含量进行比较。人工、SOWMD 和 CT 扫描测量的腹围高度相关(r=0.90-0.92,均 p<0.001)。与其他方法相比,SOWMD 测量的最小腹围能更好地预测 CT 测量的内脏脂肪组织体积(所有患者的 r=0.81,男性 r=0.87,均 p<0.001)。SOWMD 测量的最小腹围与空腹血浆葡萄糖(r=0.40,p<0.05)、甘油三酯(r=0.41,p<0.01)和高密度胆固醇(r=-0.49,p<0.001)的浓度相关。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
