Consuming energy-containing beverages may lead to weight gain, yet research investigating this issue is limited. An easily administered beverage intake assessment tool could facilitate research on this topic. The purpose of this cross-sectional investigation was to determine the validity and reliability of a self-administered beverage intake questionnaire (BEVQ) that estimates mean daily intake of beverages consumed across 19 beverage categories. Participants (N=105; aged 39+/-2 years) underwent assessments of height, weight, body mass index, and dietary intake using 4-day food intake records from June 2008 to June 2009. The BEVQ was completed at two additional visits (BEVQ1, BEVQ2). Urine samples were collected to objectively determine total fluid intake and encourage accurate self-reporting. Validity was assessed by comparing BEVQ1 with food intake record results; reliability was assessed by comparing BEVQ1 and BEVQ2. Analyses included descriptive statistics, bivariate correlations, paired samples t tests, and independent samples t tests. Self-reported water and total beverage intake (in grams) were not different between the BEVQ1 and food intake records (mean difference 129+/-77 g [P=0.096] and 61+/-106 g [P=0.567], respectively). Total beverage and sugar-sweetened beverage energy intake were significantly different, although mean differences were small (63 and 44 kcal, respectively). Daily consumption (in grams) of water (r=0.53), total beverages (r=0.46), and sugar-sweetened beverages (r=0.49) determined by the BEVQ1 were correlated with reported intake determined by the food intake record, as was energy from total beverages (r=0.61) and sugar-sweetened beverages (r=0.59) (all P values <0.001). Reliability was demonstrated, with correlations (P<0.001) detected between BEVQ1 and BEVQ2 results. The BEVQ is a valid, reliable, and rapid self-administered dietary assessment tool.
饮用含能量饮料可能会导致体重增加，但针对这一问题的研究有限。一种易于实施的饮料摄入量评估工具可能会促进对该主题的研究。这项横断面调查的目的是确定一种自我管理的饮料摄入量问卷（BEVQ）的有效性和可靠性，该问卷可估计19种饮料类别中每日饮用饮料的平均摄入量。参与者（N = 105；年龄39±2岁）使用2008年6月至2009年6月的4天食物摄入量记录，接受了身高、体重、体重指数和饮食摄入量的评估。BEVQ在另外两次访视时完成（BEVQ1、BEVQ2）。收集尿液样本以客观确定总液体摄入量，并鼓励准确的自我报告。通过将BEVQ1与食物摄入量记录结果进行比较来评估有效性；通过比较BEVQ1和BEVQ2来评估可靠性。分析包括描述性统计、双变量相关性、配对样本t检验和独立样本t检验。BEVQ1和食物摄入量记录之间自我报告的水和总饮料摄入量（以克为单位）没有差异（平均差异分别为129±77克[P = 0.096]和61±106克[P = 0.567]）。总饮料和含糖饮料的能量摄入量有显著差异，尽管平均差异较小（分别为63和44千卡）。BEVQ1确定的水（r = 0.53）、总饮料（r = 0.46）和含糖饮料（r = 0.49）的每日消费量（以克为单位）与食物摄入量记录确定的报告摄入量相关，总饮料（r = 0.61）和含糖饮料（r = 0.59）的能量也是如此（所有P值<0.001）。BEVQ1和BEVQ2结果之间检测到相关性（P<0.001），证明了可靠性。BEVQ是一种有效、可靠且快速的自我管理饮食评估工具。
