目的：我们描述了用于开发和评分17项“筛选器”的方法，该筛选器旨在估计水果和蔬菜的摄入量，脂肪和纤维的能量百分比。这个筛选器和食物频率问卷（FFQ）来衡量这些expositions.Design的能力进行评估：使用美国国家的食物消费数据，逐步多元回归被用来确定的食物被列入仪器，多元回归分析被用来开发评分算法。在三项不同的研究中评估了筛选器的性能。估计的摄入量测量的筛选和FFQ进行了比较，真正的日常摄入量的基础上的测量误差model.Setting：美国成年人population.Subjects：为开发的仪器，n=9323成人。对于测试的仪器，成年男性和女性在三项研究中完成多个24小时的饮食回忆，FFQ和筛选，n=484，462和416，respectively.Results：中位数回顾摄入量检查暴露一般估计密切的筛选。在各种验证研究中，筛选估计值和估计的真实摄入量之间的相关性为0.5-0.8。在一般情况下，性能的筛选器和完整的FFQ是相似的衰减估计低于筛选器比完整的FFQs.Conclusions：当加上适当的参考数据，筛选器的方法描述可能会产生有用的估计摄入量，监测和流行病学的目的。
Objectives: We describe the methods used to develop and score a 17-item 'screener' designed to estimate intake of fruit and vegetables, percentage energy from fat and fibre. The ability of this screener and a food-frequency questionnaire (FFQ) to measure these exposures is evaluated.Design: Using US national food consumption data, stepwise multiple regression was used to identify the foods to be included on the instrument; multiple regression analysis was used to develop scoring algorithms. The performance of the screener was evaluated in three different studies. Estimates of intakes measured by the screener and the FFQ were compared with true usual intake based on a measurement error model.Setting: US adult population.Subjects: For development of instrument, n=9323 adults. For testing of instrument, adult men and women in three studies completing multiple 24-hour dietary recalls, FFQ and screeners, n=484, 462 and 416, respectively.Results: Median recalled intakes for examined exposures were generally estimated closely by the screener. In the various validation studies, the correlations between screener estimates and estimated true intake were 0.5-0.8. In general, the performances of the screener and the full FFQ were similar; estimates of attenuation were lower for screeners than for full FFQs.Conclusions: When coupled with appropriate reference data, the screener approach described may yield useful estimates of intake, for both surveillance and epidemiological purposes.
