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.
Our study aimed to assess recent national trends in LCS consumption among children and other demographic subgroups in the United States.
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.
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.
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.
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,所有美国人的摄入量都在增加,但尚不清楚消费趋势是否因人群亚组而异。
我们的研究旨在评估美国儿童和其他人口亚组最近 LCS 消费的全国趋势。
我们使用 NHANES 数据,该数据来自 1999-2000 年至 2007-2008 年五个 2 年周期的收集。通过使用一次 24 小时膳食回忆来估计含有 LCS 的食物和饮料的消耗量。对含有 LCS 的食物和饮料的消费比例(消费流行率)进行加权,以获得全国代表性的结果。通过使用趋势卡方检验和 F 检验测试 LCS 消费和用 LCS 甜化的饮料平均摄入量的趋势。
2007-2008 年,儿童和成年人消费含有 LCS 的食物和饮料的比例有所增加。儿童中含 LCS 饮料的消费流行率从 6.1%增加到 12.5%(P 趋势<0.0001),成年人从 18.7%增加到 24.1%(P<0.001)。在儿童和成年人的所有体重、年龄、社会经济和种族-族裔亚组中,都观察到含热量的 LCS 饮料消费流行率的增加。然而,含 LCS 的无热量饮料或含 LCS 的食物的消费变化不大。
在过去十年中,美国儿童中含 LCS 的饮料消费增加了一倍。需要进一步研究了解这一趋势的健康影响。
