The objective of this study was to characterize the intakes of different types of sugars in an age- and sex-representative sample of French-speaking adults from five regions of the Province of Québec, Canada, enrolled in the cross-sectional PREDISE (PRÉDicteurs Individuels, Sociaux et Environnementaux) study ( = 1147, 18-65 years old; 50.2% women). Because only total sugar content of foods and beverages is available in the Canadian Nutrient File (CNF) 2015, the initial step of this study was thus to build a database of free and naturally occurring sugars content of each food item and recipe included in the R24W, which is an automated, self-administered, web-based, 24-h dietary recall validated to estimate nutrient intakes in French-speaking adults of the Province of Québec. Total sugars were manually differentiated into free and naturally occurring sugars using a systematic algorithm based on previously published systematic algorithms. The World Health Organization (WHO)'s free sugar definition was used to differentiate total sugars into free and naturally occurring sugars. Dietary intake estimates were assessed using three 24-h dietary recalls completed with the R24W. Mean total, free, and naturally occurring sugar intakes were 116.4 g (19.3% of daily energy intake (%E)), 72.5 g (11.7%E), and 44.0 g (7.5%E), respectively. Over half (57.3%) of the overall sample did not meet the WHO's recommendation to consume less than 10%E from free sugars. Women had a higher %E from naturally occurring sugars than men and being younger was associated with a greater %E from free sugars. Sugar intakes among French-speaking adults from the Province of Québec were mainly in the form of free sugars, with the majority of the population exceeding the WHO recommendation regarding free sugar intake. This suggests that public health efforts towards reducing free sugar intake in this population are relevant and necessary, considering that overconsumption of free sugars negatively influences health outcomes.
本研究的目的是描述加拿大魁北克省五个地区以年龄和性别为代表的讲法语成年人的不同类型糖摄入量，这些成年人参加了横断面 PREDISE（个体、社会和环境预测因素）研究（= 1147 人，年龄 18-65 岁；50.2%为女性）。由于加拿大营养素文件（CNF）2015 仅提供食物和饮料中的总糖含量，因此本研究的第一步是构建一个包含 R24W 中每种食物和配方的游离糖和天然糖含量的数据库，R24W 是一种自动化、自我管理、基于网络的 24 小时膳食回忆，经过验证可用于估计讲法语的魁北克省成年人的营养素摄入量。使用基于先前发表的系统算法的系统算法，手动将总糖分为游离糖和天然糖。使用世界卫生组织（WHO）的游离糖定义将总糖分为游离糖和天然糖。使用三个 R24W 完成的 24 小时膳食回忆评估膳食摄入量估计值。平均总糖、游离糖和天然糖摄入量分别为 116.4 克（占每日能量摄入的 19.3%[E]）、72.5 克（11.7%E）和 44.0 克（7.5%E）。超过一半（57.3%）的总体样本不符合 WHO 建议的从游离糖中摄入少于 10%E。女性的天然糖摄入量占 E 的比例高于男性，年龄越小，游离糖摄入量占 E 的比例越大。魁北克省讲法语成年人的糖摄入量主要以游离糖的形式存在，大多数人超过了 WHO 关于游离糖摄入量的建议。这表明，考虑到过量摄入游离糖会对健康结果产生负面影响，针对该人群减少游离糖摄入的公共卫生工作是相关且必要的。
