Several forms of weight for height or body mass index (BMI) are in widespread epidemiological and clinical use as measures of relative adiposity. The form derived by Benn for adults has been advocated for use in children and practical aspects of this proposition are considered.
Height and weight data from 8492 Australian schoolchildren aged 7 to 15 were studied. A subsample of 2753 children aged 9, 12 and 15 years had skinfold thicknesses measured. The sum of four skinfolds and percentage body fat predicted from skinfolds were used as measures of adiposity.
Of the various forms of power type BMI examined, weight/(height)2 was most closely associated with adiposity in this sample. Benn's assumption of low correlation between height and adiposity (which holds in adults) was not satisfied in children.
Benn's index is not recommended for general use as a body mass index in children. However, Benn's relative weight has advantages as an indirect measure of adiposity which may be of value in epidemiological studies among children.
身高体重比或体重指数（BMI）的几种形式在广泛的流行病学和临床应用中作为相对肥胖的衡量指标。本恩推导的成人形式已被提倡用于儿童，并对这一主张的实际应用方面进行了考量。
研究了8492名7至15岁澳大利亚学童的身高和体重数据。对2753名9岁、12岁和15岁儿童的子样本测量了皮褶厚度。四个皮褶厚度之和以及由皮褶厚度预测的体脂百分比被用作肥胖程度的衡量指标。
在所研究的各种幂次型BMI形式中，体重/（身高）²与该样本中的肥胖程度关联最为密切。本恩关于身高与肥胖程度之间低相关性的假设（在成人中成立）在儿童中并不成立。
不建议将本恩指数作为儿童的一般体重指数使用。然而，本恩相对体重作为肥胖程度的间接衡量指标具有优势，这在儿童流行病学研究中可能具有价值。
