To quantify the impact of temporal changes in the consumption of ultra-processed foods on obesity trends in Brazil between 2002 and 2009. We analyzed data from two Household Budget Surveys carried out in 2002/2003 ( = 182,333) and 2008/2009 ( = 190,159), which provided information on household food acquisition and individuals' weight and height. We examined the association between ultra-processed foods consumption and obesity and quantified the fraction of increase in obesity prevalence attributable to the rise in the consumption of ultra-processed foods. From 2002 to 2009, there was an increase in the obesity prevalence from 9.9% (95% CI 9.3; 10.4) to 13.2% (12.8; 13.7) while the contribution of ultra-processed foods to total energy consumption raised from 14.3% (13.4; 15.1) to 17.3% (16.5; 18.1). Ultra-processed foods consumption was positively associated with obesity prevalence. More than one quarter (28.6%) of the increase in obesity prevalence was attributable to the rise in the consumption of ultra-processed foods in the period. We found that the rise in the consumption of ultra-processed foods played a major role on the increase of obesity epidemic in Brazil.
为了量化 2002 年至 2009 年间巴西超加工食品消费的时间变化对肥胖趋势的影响。我们分析了 2002/2003 年（= 182,333）和 2008/2009 年（= 190,159）两次家庭预算调查的数据，这些数据提供了家庭食品购买和个人体重及身高的信息。我们考察了超加工食品消费与肥胖之间的关联，并量化了肥胖流行率上升归因于超加工食品消费增加的部分。2002 年至 2009 年，肥胖流行率从 9.9%（95%CI 9.3; 10.4）上升至 13.2%（12.8; 13.7），而超加工食品在总能量摄入中的占比从 14.3%（13.4; 15.1）上升至 17.3%（16.5; 18.1）。超加工食品消费与肥胖流行率呈正相关。在这一时期，肥胖流行率的上升中，有超过四分之一（28.6%）归因于超加工食品消费的增加。我们发现，超加工食品消费的增加是巴西肥胖流行率上升的主要原因。
