目的和方法：分析2000/2001年收集的具有全国代表性的全国饮食和营养调查（NDNS）数据，并研究BMI和两个中央脂肪分布的代理指标（即腰围和腰围身高比（WHtR））如何相互关联以及与心血管疾病（CVD）风险因素的关联。结果如下：仅通过BMI筛查健康风险将“错过”35%的男性和14%的女性，他们在正常BMI范围内（18.5-25 kg/m2），但具有中心脂肪分布，定义为WHtR > 0.5。在总人口中，这相当于17%的男性和6%的女性仅通过BMI进行不充分的筛查。与BMI相比，WHtR与男性和女性的CVD危险因素更密切相关。此外，在对男性和女性的综合分析中，BMI正常的中心脂肪分布与CVD风险因素水平高于无中心脂肪分布的超重相关。结论：WHtR是一种简便、有效、无创的CVD危险因素筛查工具。我们提出的0.5的边界值转化为一个简单的公共卫生信息：“保持你的腰围小于你身高的一半”。
Objective and Method: To analyse data from the nationally representative National Diet and Nutrition Survey (NDNS) collected in 2000/2001 and to investigate how the BMI and two proxy indicators of central fat distribution, namely the waist circumference and the waist to height ratio (WHtR), are associated with each other and with cardiovascular disease (CVD) risk factors. Results: Screening health risk by BMI alone would 'miss' 35% of men and 14% of women who are within the normal BMI range (18.5-25 kg/m(2)) but have central fat distribution, defined by WHtR > 0.5. In the total population this equates to 17% of all men and 6% of all women who would be inadequately screened by BMI alone. Compared to BMI, WHtR was more closely associated with CVD risk factors among both men and women. Furthermore, in a combined analysis of men and women, central fat distribution with a normal BMI was associated with higher levels of CVD risk factors than being overweight without central fat distribution. Conclusion: WHtR is a simple and effective, non-invasive screening tool for CVD risk factors. Our proposed boundary value of 0.5 translates into a simple public health message: 'Keep your waist circumference to less than half your height'.
