Abstract
Reducing free sugars intake is important for the prevention of dental caries and obesity in children. The study aimed to determine the amount and sources of free sugars known to contribute to dental caries, and identify sociodemographic determinants of intake by children aged 5 years in Australia. Cross‐sectional analysis of dietary data from a cohort study, collected using a customized food frequency questionnaire were used to calculate free sugars intake as grams/day and percentage contribution to Estimated Energy Requirement (EER). The percent contribution of food sources to free sugars intake was derived. Sociodemographic determinants of achieving intakes within WHO thresholds (i.e., <5% and <10% Energy were explored with multinomial logistic regression. Complete data were available for 641 children (347 boys, 294 girls). Median (IQR) free sugars intake (g/day) was 31.6 (21.3–47.6) in boys and 28.1 (19.6–47.9) in girls. The median (IQR) percentage contribution to EER was 7.9 (5.4–12.7); 21% and 42% of children had intakes <5% EER and between 5% and <10%, respectively. The main sources of free sugars were: (1) Cakes, Biscuits and Cereal Bars; (2) Sweetened Milk Products (predominantly yoghurts) and (3) Desserts. Maternal university education, single‐parent household, and maternal place of birth being Australia or New Zealand were associated with free sugars intake <5% EER. In conclusion, less than a quarter of 5‐year‐old children in the SMILE cohort achieved the WHO recommendations to limit free sugars to <5% EER. Strategies to lower free sugars intake could target priority populations such migrants, populations with lower levels of education or health literacy and identify areas for intervention in the wider food environments that children are exposed to.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance

要点】:研究确定了5岁澳大利亚儿童自由糖摄入的来源与量,并识别了社会人口学决定因素,发现不到四分之一的孩子达到世界卫生组织推荐的自由糖摄入量。

方法】:通过横断面分析使用定制食物频率问卷收集的队列研究饮食数据,计算自由糖摄入量(克/天)及其对估计能量需求(EER)的百分比贡献。

实验】:对641名儿童的完整数据进行分析,发现男孩和女孩的自由糖摄入中位数分别为31.6克/天和28.1克/天,主要来源为糕点、甜味牛奶产品和甜点,与母亲的教育水平、单亲家庭结构和母亲的出生地有关,且仅有21%的儿童自由糖摄入量低于EER的5%。数据来源于SMILE队列研究。
