水果和蔬菜(F/V)摄入量监测可提供对设计和评估干预措施以及评估实现国家摄入量目标进展情况至关重要的信息。疾控中心的青少年危险行为监测系统(YRBSS)使用六个关于每天摄入次数的问题来评估高中生的F/V摄入量。目前尚不清楚每天的F/V摄入量频率是否可以作为每天摄入量的替代指标。比较基于对三组调查问题的回答的F/V摄入量估计值，包括六个YRBSS标准问题集，以及基于24小时饮食回忆访谈数据的标准F/V摄入量。研究参与者是610名高中生，他们完成了一份课堂问卷和三次电话管理的24小时饮食回忆访谈。问卷询问学生在过去7天内(第1组)摄入100%果汁和食用水果、胡萝卜、土豆、蔬菜沙拉和其他蔬菜的次数(第1组)，他们昨天这样做的次数(第2组)，以及他们每天摄入的水果和蔬菜当量的数量(第3组)。平均估计F/V摄入量为“次数/天”或“服务/天”，以及估计F/V摄入量为≥1、≥2和≥3次/天或服务/天的学生的百分比。使用t检验和校正的皮尔逊相关性来比较基于调查问题回答的F/V摄入量估计值与基于对24小时饮食回忆访谈的回答的估计值。根据对所有调查问题的回答而估计的F/V平均摄入量(以次数/天或服务/天)明显多于基于对24小时饮食回忆访谈的回答而估计的服务/天，达到每个摄入量临界点的学生的百分比也更高。在三组调查问题中，YRBSS的标准问题产生的估计值和百分比最接近24小时饮食回忆访谈估计值。对于高中学生的简短自填式问卷，建议使用当前的YRBSS问题来监测F/V的摄入量，尽管以次数/天为单位的平均摄入量估计值可能会高于或不能替代以服务/日为单位的平均摄入量估计值。
Fruit and vegetable (F/V) intake surveillance can provide information critical to the design and evaluation of interventions and the assessment of progress toward national intake objectives. The CDC’s Youth Risk Behavior Surveillance System (YRBSS) assesses F/V intake among high school students using six questions about the frequency of intake in times per day. It is not known whether F/V intake frequency in times per day can be used as a proxy for intake in servings per day. To compare F/V intake estimates based on responses to three sets of survey questions, including the standard set of six YRBSS questions, with criterion F/V intake in servings per day based on data from 24-hour dietary recall interviews. Study participants were 610 high school students who completed an in-class questionnaire and three telephone-administered 24-hour dietary recall interviews. The questionnaire asked students how many times they consumed 100% fruit juice and ate fruit, carrots, potatoes, green salad, and other vegetables during the “past 7 days” (set 1), the number of times they did so “yesterday” (set 2), and the number of cup-equivalents of fruits and vegetables they consumed per day (set 3). Mean estimated F/V intake either as “times/day” or “servings/day” and the percentage of students whose estimated F/V intake was ≥1, ≥2, and ≥3 times/day or servings/day. t tests and corrected Pearson correlations were used to compare F/V intake estimates based on survey question responses with estimates based on responses to the 24-hour dietary recall interviews. Mean F/V intake estimates (in times/day or servings/day) based on responses to all sets of survey questions were significantly more than servings/day estimates based on responses to the 24-hour dietary recall interviews, and the percentages of students meeting each intake cutpoint were also more. Of the three sets of survey questions, the standard YRBSS questions produced estimates and percentages that were most consistently closest to 24-hour dietary recall interview estimates. For brief self-administered questionnaires of high school students, the current YRBSS questions are recommended for monitoring F/V intake even though mean intake estimates in times/day will likely be higher than, and are not a proxy for, mean intake estimates in servings/day.
