This study assessed associations between ultraprocessed food consumption and dietary nutrient profile linked to obesity in children and adolescents in Argentina, Australia, Brazil, Chile, Colombia, Mexico, the United Kingdom, and the United States using nationally representative data collected between 2004 and 2014. Linear regression models were used to evaluate associations between dietary share of ultraprocessed foods (country and age group-specific quintiles and a 10% share increase) and the energy density of diets and their content of free sugars and fiber. Ultraprocessed foods, defined by the NOVA system, ranged from 18% of total energy intake among preschool children in Colombia to 68% among adolescents in the United Kingdom. In almost all countries and age groups, increases in the dietary share of ultraprocessed foods were associated with increases in energy density and free sugars and decreases in fiber, suggesting that ultraprocessed food consumption is a potential determinant of obesity in children and adolescents. Effective global policy action to address growing ultraprocessed food consumption and childhood obesity is urgently needed.
本研究利用 2004 年至 2014 年间收集的全国代表性数据，评估了阿根廷、澳大利亚、巴西、智利、哥伦比亚、墨西哥、英国和美国儿童和青少年超加工食品消费与与肥胖相关的饮食营养状况之间的关联。线性回归模型用于评估超加工食品（按国家和年龄组划分的五分位数和 10%的份额增加）在饮食中的比例与饮食能量密度及其游离糖和纤维含量之间的关联。根据 NOVA 系统定义，超加工食品占哥伦比亚学龄前儿童总能量摄入的 18%，占英国青少年总能量摄入的 68%。在几乎所有国家和年龄组中，超加工食品在饮食中所占比例的增加与能量密度和游离糖的增加以及纤维的减少有关，这表明超加工食品的消费可能是儿童和青少年肥胖的一个决定因素。迫切需要采取有效的全球政策行动来解决超加工食品消费和儿童肥胖问题。
