尽管身体质量指数（BMI）在关于健康的讨论中无处不在，但在将其用作当前异常与未来风险的生物标志物方面存在模糊性。这种区别对于了解身体大小与健康之间的关系以及被认为具有不正常和“不健康”身体的个人来说是必然的。因此，本次审查有三个目的。首先是区分这种“生物标志物”的观点，从现有的批评BMI作为健康行为的代理或作为肥胖作为一种疾病的定义特征。第二是强调将BMI视为衡量已达到的不健康状况的指标，而不是风险的概率指标。最后，本文并没有呼吁废除BMI，而是认为继续使用BMI“只是一个数字”符合研究和实践中体重中立的要求。该综述的结论是，在关于COVID-19的公共卫生信息中，体型的风险和不健康是如何被混为一谈的。BMI是一个风险标志，但它作为COVID-19严重程度的替代品，将身体大小等同于健康，在持续的大流行中塑造了关于脆弱性和个人责任的信念。
Despite the ubiquity of the body mass index (BMI) in discourse on health, there is ambiguity in its use as a biomarker of current abnormality versus future risk. This distinction is consequential for knowledge of the relationship between body size and health, as well as for individuals deemed to have abnormal and “unhealthy” bodies. Consequently, the purposes of this review are threefold. The first is to differentiate this ‘biomarker’ perspective from extant critiques of BMI as a proxy for health behaviors or as the defining characteristic of obesity as a disease. The second is to highlight the shift towards treating BMI as a measure of attained unhealthiness, rather than a probabilistic indicator of risk. Finally, rather than call for the abolition of BMI, this paper argues that its continued use as ‘just a number’ is in keeping with the push for weight neutrality in research and practice. The review concludes by demonstrating how the riskiness and unhealthiness of body size is conflated in public health messaging on COVID-19. BMI is a marker of risk, but its use as a surrogate for COVID-19 severity equates body size with health, shaping beliefs about vulnerability and personal responsibility amid an ongoing pandemic.
