Body mass index (BMI) corrects body weight for height and is well established for diagnosing overweight and obesity and correlating with many medical conditions. Waist circumference (WC) is used to diagnose abdominal obesity. However, the correlation of BMI and WC is high, around 0.9, making the use of BMI and WC in concert challenging. A body shape index (ABSI) is a new measure of risk associated with abdominal size. Derived in 2012, ABSI is analogous to BMI in that it normalizes WC for weight and height (and thus to BMI). A similar derivation led to hip index (HI), normalizing hip circumference for BMI. Hazard ratios (HRs) for univariate risk associations of the independent measures height, BMI, ABSI, and HI can be multiplied to give a combined HR, the anthropometric risk indicator (ARI). Compared to any one anthropometric factor, including BMI and WC, ARI more accurately estimates personalized mortality hazard. Published work on ABSI, HI, and ARI supports their association with many aspects of health, including cardiometabolic conditions related to the metabolic syndrome.
体重指数（BMI）根据身高对体重进行校正，在诊断超重和肥胖以及与多种疾病的关联方面已得到广泛应用。腰围（WC）用于诊断腹型肥胖。然而，BMI与WC的相关性很高，约为0.9，这使得同时使用BMI和WC具有挑战性。体型指数（ABSI）是一种与腹部大小相关的新风险指标。ABSI于2012年推出，与BMI类似，它通过体重和身高（进而与BMI）对WC进行标准化。类似的推导得出了臀围指数（HI），通过BMI对臀围进行标准化。独立测量指标身高、BMI、ABSI和HI的单变量风险关联的风险比（HRs）可以相乘得出一个综合HR，即人体测量风险指标（ARI）。与任何一个人体测量因素（包括BMI和WC）相比，ARI能更准确地估计个性化死亡风险。关于ABSI、HI和ARI的已发表研究支持它们与健康的许多方面相关，包括与代谢综合征相关的心脏代谢疾病。
