Implementation of strategies to address obesity on a global scale has not yet begun in earnest. One key issue is uncertainty about the relative importance of taking aggressive action on the food vs. physical activity side of the energy balance equation, recognizing that interventions in both areas are critical. Using data on obesity prevalence, food availability, and selected economic and sociodemographic indicators from member countries of the Organization for Economic Cooperation and Development, an article in this volume of the Annual Review of Public Health provides estimates and projections to help resolve this uncertainty. The analyses presented support the authors' hypothesis that most of the recent rise in obesity is attributable to excess caloric intake. The implication that policies to curb overconsumption might include deliberate changes in the price structure of the food supply should stimulate debate about our current agricultural and trade paradigms, particularly because any such global policies would also affect the developing world.
在全球范围内认真实施应对肥胖问题的策略尚未真正开始。一个关键问题是，在能量平衡等式中，针对食物与身体活动方面采取积极行动的相对重要性存在不确定性，要认识到这两个领域的干预措施都至关重要。利用经济合作与发展组织成员国的肥胖患病率、食物供应以及选定的经济和社会人口指标数据，《公共卫生年度评论》本期的一篇文章提供了估计和预测，以帮助解决这一不确定性。所呈现的分析支持了作者的假设，即近期肥胖率上升的大部分原因是热量摄入过多。抑制过度消费的政策可能包括有意改变食物供应的价格结构，这一观点应该会引发对我们当前农业和贸易模式的讨论，特别是因为任何此类全球政策也会影响发展中世界。
