This article provides an analysis of the use of artificial sweeteners, caffeine, and excess fluids in patients diagnosed with anorexia nervosa (AN).
Seventy participants with AN were recruited to participate in an ecologic momentary assessment study which included nutritional analysis using the Nutrition Data Systems for Research, a computer based dietary recall system.
When subtypes were compared, participants with AN-restricting subtype (AN-R) and participants with AN-Binge-Purge (AN-B/P) did not differ in quantity of aspartame, caffeine, or water consumed. Daily water consumption was related to daily vomiting frequency in AN-B/P but not to daily exercise frequency in either participants with AN-R or AN-B/P.
Caffeine, water, and aspartame consumption can be variable in patients with AN and the consumption of these substances seems to be only modestly related to purging behavior.
本文对被诊断为神经性厌食症（AN）的患者使用人工甜味剂、咖啡因和过量液体的情况进行了分析。
招募了70名神经性厌食症患者参与一项生态瞬时评估研究，该研究包括使用研究用营养数据系统进行营养分析，这是一个基于计算机的饮食回顾系统。
在比较各亚型时，限制型神经性厌食症（AN-R）患者和暴食-清除型神经性厌食症（AN-B/P）患者在阿斯巴甜、咖啡因或水的摄入量上没有差异。每日饮水量与AN-B/P患者的每日呕吐频率有关，但与AN-R患者或AN-B/P患者的每日运动频率均无关。
神经性厌食症患者的咖啡因、水和阿斯巴甜摄入量可能存在差异，这些物质的摄入似乎与清除行为仅有适度关联。
