Because childhood obesity is such a threat to the physical, mental, and social health of youth, there is a great need to identify effective strategies to reduce its prevalence. The objective of this study was to estimate the mean calories from added sugars that are saved by switching sugar-sweetened beverages (including soda, fruit-flavored drinks, and sport drinks) and flavored milks consumed to unflavored low-fat milk (<1% fat) at meals and water between meals. Simulation analyses used 24-hour dietary recall data from the third School Nutrition Dietary Assessment Study (n=2,314), a 2005 national cross-sectional study of schools and students participating in the National School Lunch Program, to estimate changes in mean calories from added sugars both at and away from school. Overall, these changes translated to a mean of 205 calories or a 10% savings in energy intake across all students (8% among children in elementary school and 11% in middle and high schools). Eighty percent of the daily savings were attributed to beverages consumed away from school, with results consistent across school level, sex, race/ethnicity, and weight status. Children's consumption of sugar-sweetened beverages at home contributed the greatest share of empty calories from added sugars. Such findings indicate that parental education should focus on the importance of reducing or eliminating sugar-sweetened beverages served at home. This conclusion has implications for improving children's food and beverage environments for food and nutrition educators and practitioners, other health care professionals, policy makers, researchers, and parents.
由于儿童肥胖对青少年的身心健康和社交健康构成如此大的威胁,因此非常有必要确定有效的策略来降低其流行率。本研究的目的是估算通过用无甜味低脂奶(<1%脂肪)代替餐时和两餐间饮用的加糖饮料(包括苏打水、果味饮料和运动饮料)和调味奶,可以节省的添加糖的平均卡路里。模拟分析使用了第三次学校营养饮食评估研究(School Nutrition Dietary Assessment Study,SN-DAS)的 24 小时饮食记录数据(n=2314),这是一项 2005 年对参与国家学校午餐计划(National School Lunch Program)的学校和学生进行的全国性横断面研究,以估算在校内和校外添加糖的平均卡路里变化。总的来说,这些变化使所有学生的平均能量摄入减少了 205 卡路里,即 10%(小学儿童为 8%,中学和高中儿童为 11%)。80%的日常节省归因于校外饮用的饮料,学校水平、性别、种族/民族和体重状况均有一致的结果。儿童在家中饮用含糖饮料会摄入最多的添加糖空卡路里。这些发现表明,家长教育应重点关注减少或消除在家中供应含糖饮料的重要性。这一结论对改善儿童的食物和饮料环境具有重要意义,这对于食品和营养教育工作者和从业者、其他卫生保健专业人员、政策制定者、研究人员和家长都有影响。
