从1985年到2016年，大多数地区的体重不足患病率下降，肥胖和严重肥胖患病率上升，但这些变化的幅度在各地区之间存在显著差异。我们调查了平均体重指数（BMI）的变化在多大程度上解释了不同地区体重不足、肥胖和严重肥胖患病率的变化，使用了来自2896项基于人口的研究（1.87亿参与者）的数据。体重不足和总体肥胖患病率的变化，以及在较小程度上严重肥胖的变化，在很大程度上是由BMI分布的变化驱动的，分布形状变化的贡献较小。在东亚、东南亚和撒哈拉以南非洲，随着BMI分布的转移，体重过轻的尾巴被抛在后面。需要制定政策，解决各种形式的营养不良问题，使人们能够获得和负担得起健康食品，同时通过财政和监管限制限制不健康食品。
From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions.
