To analyze the contribution of ultra-processed foods to the intake of free sugars among different age groups in Australia.
Dietary intakes of 12,153 participants from the National Nutrition and Physical Activity Survey (2011-12) aged 2+ years were evaluated. Food items collected through two 24-h recalls were classified according to the NOVA system. The contribution of each NOVA food group and their subgroups to total energy intake was determined by age group. Mean free sugar content in diet fractions made up exclusively of ultra-processed foods, or of processed foods, or of a combination of un/minimally processed foods and culinary ingredients (which includes table sugar and honey) were compared. Across quintiles of the energy contribution of ultra-processed foods, differences in the intake of free sugars, as well as in the prevalence of excessive free sugar intake (≥ 10% of total energy) were examined.
Ultra-processed foods had the highest energy contribution among children, adolescents and adults in Australia, with older children and adolescents the highest consumers (53.1% and 54.3% of total energy, respectively). The diet fraction restricted to ultra-processed items contained significantly more free sugars than the two other diet fractions. Among all age groups, a positive and statistically significant linear association was found between quintiles of ultra-processed food consumption and both the average intake of free sugars and the prevalence of excessive free sugar intake.
Ultra-processed food consumption drives excessive free sugar intake among all age groups in Australia.
分析超加工食品对澳大利亚不同年龄组人群游离糖摄入量的贡献。
评估了来自全国营养和身体活动调查（2011-12 年）的 12153 名 2 岁及以上参与者的膳食摄入量。通过两次 24 小时回忆收集的食物项目按照 NOVA 系统进行分类。按年龄组确定每个 NOVA 食品组及其亚组对总能量摄入的贡献。仅由超加工食品、加工食品或未加工/最低限度加工食品和烹饪原料（包括食糖和蜂蜜）组成的饮食部分的游离糖平均含量进行了比较。在超加工食品能量贡献的五分位数中，检查了游离糖摄入量以及过量游离糖摄入（占总能量的≥10%）的发生率的差异。
超加工食品在澳大利亚儿童、青少年和成年人中的能量贡献最高，年龄较大的儿童和青少年是最高的消费者（分别占总能量的 53.1%和 54.3%）。仅限于超加工项目的饮食部分含有明显更多的游离糖。在所有年龄组中，超加工食品消费的五分位数与游离糖的平均摄入量和过量游离糖摄入的流行率之间存在正相关且具有统计学意义。
超加工食品的消费导致澳大利亚所有年龄组人群游离糖摄入过量。
