High consumption of ultra-processed foods and drinks (UPF) has been linked to poor diet quality and an increased risk of non-communicable diseases. To inform public policies and interventions aimed at reducing UPF intake in Canada, updated information on UPF intake among different sociodemographic groups is needed. This study, using data from 5872 adults aged 18 years and older from the International Food Policy Study (2018-2019), aims to estimate the dietary energy contribution of UPF and assess its variation among sociodemographic subgroups. All foods and drinks reported in a single 24 h dietary recall were classified using the Nova system. We estimated the mean proportion of total daily energy from UPF and subcategories of UPF in the overall sample and among sociodemographic subgroups. Multivariable linear regression models evaluated the association between sociodemographic characteristics with the proportion of total daily energy from UPF. On average, adults consumed 45.2% of their total daily energy from UPF. UPF consumption was slightly higher among males than females (49.4% vs. 47.6%, = 0.039) and younger adults aged 19-30 years compared with older adults aged 51-64 years (50.0% vs. 47.2%, = 0.029), adjusting for a range of sociodemographic factors. Overall, UPF consumption was relatively high among adults in all sociodemographic subgroups, highlighting the need for policies to decrease UPF consumption in the entire population.
超加工食品和饮料（UPF）的高消费量与不良饮食质量及非传染性疾病风险增加有关。为了为旨在减少加拿大UPF摄入量的公共政策和干预措施提供信息，需要有关不同社会人口群体中UPF摄入量的最新信息。本研究利用国际粮食政策研究（2018 - 2019年）中5872名18岁及以上成年人的数据，旨在估计UPF的膳食能量贡献，并评估其在社会人口亚组中的差异。通过诺瓦系统对单次24小时饮食回顾中报告的所有食品和饮料进行分类。我们估计了总体样本以及社会人口亚组中UPF及UPF子类别占每日总能量的平均比例。多变量线性回归模型评估了社会人口特征与UPF占每日总能量比例之间的关联。平均而言，成年人每日总能量的45.2%来自UPF。在调整一系列社会人口因素后，男性的UPF消费量略高于女性（49.4%对47.6%，P = 0.039），19 - 30岁的年轻人高于51 - 64岁的老年人（50.0%对47.2%，P = 0.0
