Several organizations recommend the use of measures of abdominal obesity in conjunction with body mass index (BMI) to assess obesity-related health risk. Recent evidence suggests that waist circumference (WC), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) are increasing within BMI categories. This shift may have affected the usefulness of abdominal obesity measures.
Data are from respondents aged 18 to 79 to the 2007 to 2009 Canadian Health Measures Survey. Using logistic regression, this paper examines cardiovascular disease (CVD) risk factors in relation to WC, WHR and WHtR within BMI health-risk categories. CVD risk factors considered include components of the metabolic syndrome.
Among men in the normal and overweight BMI categories, WHR and WHtR were positively associated with having at least two CVD risk factors. All three abdominal obesity measures were associated with increased odds of having at least two CVD risk factors among normal-weight women. Abdominal obesity was not associated with CVD risk factors for people in obese class I.
Among men and women in the normal BMI category, measures of abdominal obesity are associated with increased odds of CVD risk factors. This underscores the importance of measuring and monitoring abdominal obesity in normal-weight men and women.
一些组织建议使用腹部肥胖测量指标与体重指数（BMI）相结合，以评估与肥胖相关的健康风险。最近的证据表明，腰围（WC）、腰臀比（WHR）和腰高比（WHtR）在 BMI 类别内呈上升趋势。这种转变可能影响了腹部肥胖测量指标的有效性。
数据来自于 2007 年至 2009 年加拿大健康测量调查中 18 至 79 岁的受访者。本文使用逻辑回归，研究了 WC、WHR 和 WHtR 与 BMI 健康风险类别中 CVD 风险因素的关系。考虑到的 CVD 风险因素包括代谢综合征的组成部分。
在正常和超重 BMI 类别的男性中，WHR 和 WHtR 与至少有两个 CVD 风险因素呈正相关。在正常体重女性中，所有三种腹部肥胖测量指标均与至少有两个 CVD 风险因素的几率增加有关。对于肥胖 I 级的人群，腹部肥胖与 CVD 风险因素无关。
在正常 BMI 类别的男性和女性中，腹部肥胖测量指标与 CVD 风险因素的几率增加有关。这强调了在正常体重的男性和女性中测量和监测腹部肥胖的重要性。
