Few data assessing non-nutritive sweetener (NNS) intake are available, especially within rural, health-disparate populations, where obesity and related co-morbidities are prevalent. The objective of this study is to characterize NNS intake for this population and examine the variance in demographics, cardio-metabolic outcomes, and dietary intake between NNS consumers and non-consumers. A cross-sectional sample ( = 301) of Virginian adults from a randomized controlled trial (data collected from 2012 to 2014) targeting sugar-sweetened beverage (SSB) intake completed three 24-h dietary recalls, and demographics and cardio-metabolic measures were assessed. The frequency, types, and sources of NNS consumption were identified. Thirty-three percent of participants reported consuming NNS ( = 100). Sucralose was the largest contributor of mean daily NNS intake by weight (mg), followed by aspartame, acesulfame potassium, and saccharin. NNS in tabletop sweeteners, diet tea, and diet soda were the top contributors to absolute NNS intake. The most frequently consumed NNS sources were diet sodas, juice drinks, and tabletop sweeteners. Although mean body mass index (BMI) was greater for NNS consumers, they demonstrated significantly lower food, beverage, and SSB caloric intake and energy density, and higher overall dietary quality. It remains unclear whether NNS use plays a role in exacerbating weight gain. NNS consumers in this sample may have switched from drinking predominantly SSB to drinking some NNS beverages in an effort to cope with weight gain. Future studies should explore motivations for NNS use across a variety of weight and health categories.
评估非营养性甜味剂（NNS）摄入量的数据很少，尤其是在农村地区健康状况存在差异的人群中，肥胖及相关合并症在这些人群中很普遍。本研究的目的是描述该人群的NNS摄入量，并研究NNS消费者与非消费者在人口统计学、心血管代谢结果和饮食摄入量方面的差异。从一项针对含糖饮料（SSB）摄入量的随机对照试验（2012年至2014年收集的数据）中选取了301名弗吉尼亚州成年人作为横断面样本，他们完成了三次24小时饮食回顾，并评估了人口统计学和心血管代谢指标。确定了NNS消费的频率、类型和来源。33%的参与者报告食用过NNS（n = 100）。按重量（毫克）计算，三氯蔗糖是平均每日NNS摄入量的最大贡献者，其次是阿斯巴甜、乙酰磺胺酸钾和糖精。桌面甜味剂、减肥茶和无糖苏打水中的NNS是绝对NNS摄入量的主要贡献者。最常食用的NNS来源是无糖苏打水、果汁饮料和桌面甜味剂。尽管NNS消费者的平均体重指数（BMI）较高，但他们的食物、饮料和SSB热量摄入量及能量密度显著较低，整体饮食质量较高。NNS的使用是否在加剧体重增加方面起作用仍不清楚。该样本中的NNS消费者可能已从主要饮用SSB转向饮用一些NNS饮料，以应对体重增加。未来的研究应探讨不同体重和健康类别中使用NNS的动机。
