身体质量指数(BMI)是身高体重比,具体公式是BMI=体重(千克)÷身高(米)的平方。长期以来,BMI一直是判定一个人胖瘦的关键指标。然而,最新研究发现,BMI也并非测量肥胖或健康状况的最好方法。但是要得出另一种可取代BMI的快速计算公式也绝非易如反掌。南加州大学一项新研究提出一种新方法:身体脂肪指数(BAI或BFI),主要测量的是臂围与身高之比。研究分析了1700名墨西哥裔美国人的相关信息,如性别、年龄、身高、体重、臀围或几种因素的叠加等情况。结果发现,臀围
Body mass index (BMI) is height to weight ratio, the specific formula is BMI = weight (kg) ÷ height (meters) squared. For a long time, BMI has been the key indicator to judge a person’s fat and thin. However, the latest study found that BMI is not the best way to measure obesity or health status. But to come up with another fast calculation formula that can replace BMI is not easy. A new study by the University of Southern California proposes a new approach: the Body Fat Index (BAI or BFI), which measures the arm-to-height ratio. The study analyzed information about 1700 Mexican Americans, such as gender, age, height, weight, hip circumference, or a combination of several factors. The results found that hip circumference
