BACKGROUND
"A Body Shape Index" (ABSI) is a recently proposed index that standardizes waist circumference for body mass index (BMI) and height. This study aims to: (a) examine if the ABSI scaling exponents for standardizing waist circumference for BMI and height are valid in middle-aged and older Indonesian population, and (b) compare the association between incident hypertension and ABSI and other anthropometric measures.
METHODS AND FINDINGS
The Indonesian Family Life Survey Wave 3 measured anthropometric variables and blood pressure of 8255 adults aged between 40 to 85 years in 2000. The relationship between two anthropometric quantities, e.g. weight (w) and height (h), can be expressed as the power law-equivalent [Formula: see text], where p = 2 is the scaling exponent in the derivation of the BMI and can be estimated by linear regression analysis. This was extended to the regression analysis of the log-transformed waist circumference, weight and height to establish the scaling exponents in the ABSI. The values for men were similar to those developed by the previous American study, which were 2/3 (BMI) and 1/2 (height). Those for women were somewhat smaller, at 3/5 (BMI) and 1/5 (height). The original (American) ABSI leads to mild negative correlation with BMI (-0.14) and height (-0.12) in the female population. Analysis of the development of hypertension between Waves 3 and 4 (average interval 7.5 years) in relation to ABSI measured at Wave 3 showed stronger association if the locally derived (Indonesian) scaling exponents were used. However, both versions of the ABSI were less associated with incident hypertension than waist circumference and BMI.
CONCLUSIONS
The values for the scaling exponents for ABSI are roughly similar between the American population and the middle-aged and older Indonesian population, although larger discrepancy was found in women. The ABSI is less associated with incident hypertension than waist circumference and BMI.
背景
“体脂指数”（ABSI）是一种最近提出的指数，它为体重指数（BMI）和身高标准化了腰围。本研究旨在：（a）检验 ABSI 为 BMI 和身高标准化腰围的标度指数是否在中年和老年印度尼西亚人群中有效，以及（b）比较 ABSI 与其他人体测量指标与高血压发病之间的关联。
方法和发现
印度尼西亚家庭生活调查第三波在 2000 年测量了 8255 名 40 至 85 岁成年人的人体测量变量和血压。两个人体测量量（例如体重（w）和身高（h））之间的关系可以表示为幂律等价式[公式：见文本]，其中 p = 2 是 BMI 推导中的标度指数，可以通过线性回归分析来估计。这被扩展到对体重、身高和腰围的对数转换进行回归分析，以建立 ABSI 的标度指数。男性的数值与之前美国研究开发的数值相似，分别为 2/3（BMI）和 1/2（身高）。女性的数值略小，分别为 3/5（BMI）和 1/5（身高）。女性人群中原始（美国）ABSI 与 BMI（-0.14）和身高（-0.12）呈轻度负相关。在与第 3 波测量的 ABSI 相关的第 3 波和第 4 波（平均间隔 7.5 年）之间高血压发展的分析中，如果使用本地（印度尼西亚）衍生的标度指数，则显示出更强的关联。然而，ABSI 与高血压发病的关联程度均低于腰围和 BMI。
结论
ABSI 的标度指数值在美国人群和中年及以上印度尼西亚人群之间大致相似，尽管女性的差异更大。ABSI 与高血压发病的关联程度低于腰围和 BMI。
