世卫组织专家磋商会讨论了关于如何解释确定亚洲人群超重和肥胖的推荐身体质量指数（BMI）分界点的争论，并考虑了是否有必要为特定人群设立BMI分界点。他们回顾了科学证据，表明亚洲人群与欧洲人群相比，在身体质量指数、体脂百分比和健康风险之间存在不同的关联。磋商得出的结论是，bmi低于世卫组织现有的超重分界点（大于或等于25 kg/m）时，亚洲2型糖尿病和心血管疾病高危人群的比例很大。然而，现有数据并不一定表明所有亚洲人超重或肥胖的BMI分界点。在不同的亚洲人群中，观察到的风险临界值从22 kg/m(2)到25 kg/m(2)不等；对于高危人群，从26 kg/m(2)到31 kg/m(2)不等。因此，没有试图分别为每个人口重新定义截止点。磋商会还同意应保留世卫组织BMI分界点作为国际分类。磋商会确定了进一步可能采取的公共卫生行动，BMI连续线上的点（23.0、27.5、32.5和37.5 kg/m(2)），并提出了各国可据此决定其人口风险增加定义的方法。
A WHO expert consultation addressed the debate about interpretation of recommended body-mass index (BMI) cut-off points for determining overweight and obesity in Asian populations, and considered whether population-specific cut-off points for BMI are necessary. They reviewed scientific evidence that suggests that Asian populations have different associations between BMI, percentage of body fat, and health risks than do European populations. The consultation concluded that the proportion of Asian people with a high risk of type 2 diabetes and cardiovascular disease is substantial at BMIs lower than the existing WHO cut-off point for overweight (greater than or equal to25 kg/m(2)). However, available data do not necessarily indicate a clear BMI cut-off point for all Asians for overweight or obesity. The cut-off point for observed risk varies from 22 kg/m(2) to 25 kg/m(2) in different Asian populations; for high risk it varies from 26 kg/m(2) to 31 kg/m(2). No attempt was made, therefore, to redefine cut-off points for each population separately. The consultation also agreed that the WHO BMI cut-off points should be retained as international classifications. The consultation identified further potential public health action, points (23.0, 27.5, 32.5, and 37.5 kg/m(2)) along the continuum of BMI, and proposed methods by which countries could make decisions about the definitions of increased risk for their population.
