背景：低热量和无热量甜味剂（LCS）已成为添加糖的替代品。研究表明，所有美国人的消费正在增加，但它是未知的消费趋势是否不同的人口subgroup.Objective：我们的研究旨在评估最近的全国趋势LCS消费儿童和其他人口subgroupin the United States.Design：我们使用NHANES数据收集在5个2-y周期从1999-2000年到2007-2008年。使用一个24小时的饮食回忆，估计消费的食物和饮料与LCS。对消费含有LCS的食品和饮料的人口比例（消费流行率）进行了加权，以获得具有全国代表性的结果。LCS消费和平均摄入量的饮料加糖与LCS的流行趋势进行了测试，通过使用卡方检验的趋势和F tests.Results：在2007-2008年，儿童和成人消费的食品和饮料中含有LCS的百分比增加。儿童中饮用有LCS的饮料的患病率从6.1%增加到12.5%（P趋势< 0.0001），成人中从18.7%增加到24.1%（P < 0.001）。在儿童和成人的所有体重、年龄、社会经济和种族-民族亚组中，观察到含卡路里饮料和LCS的消费流行率增加。然而，在消费的无热量饮料与LCS或含LCS的食品变化不大被发现。结论：在过去的十年中，美国儿童的消费量增加了一倍含LCS的饮料。需要进一步的研究来了解这一趋势对健康的影响。美国临床营养杂志2012;96：640-6.
Background: Low-calorie and no-calorie sweeteners (LCSs) have emerged as alternatives to added sugars. Research suggests that consumption among all Americans is increasing, yet it is unknown whether consumption trends differ among population subgroups.Objective: Our study aimed to assess recent national trends in LCS consumption among children and other demographic subgroups in the United States.Design: We used NHANES data collected in five 2-y cycles from 1999-2000 to 2007-2008. Consumption of foods and beverages with LCSs was estimated by using one 24-h dietary recall. Estimates of the proportion of the population consuming foods and beverages containing LCSs (prevalence of consumption) were weighted to obtain nationally representative results. Trends in prevalence of LCS consumption and mean intake of beverages sweetened with LCSs were tested by using chi-square tests for trend and F tests.Results: In 2007-2008, the percentage of children and adults consuming foods and beverages containing LCSs increased. The prevalence of consuming beverages with LCSs increased from 6.1% to 12.5% among children (P-trend < 0.0001) and from 18.7% to 24.1% among adults (P < 0.001). Increases in the prevalence of consumption of calorie-containing beverages with LCSs were observed among all weight, age, socioeconomic, and race-ethnicity subgroups in both children and adults. However, little change in consumption of no-calorie beverages with LCSs or LCS-containing foods was found.Conclusions: The consumption of LCS-containing beverages has doubled among US children over the past decade. Further research is needed to understand the health effects of this trend. Am J Clin Nutr 2012;96:640-6.
