食物频率调查问卷(FFQ)是一种经常用于大规模营养流行病学研究的膳食评估工具。本研究的目标是验证夏威夷FFQ的自我管理版本，该版本经过修改后适用于纽芬兰和拉布拉多(NL)的普通成人人口。在一年的时间里，195名随机选择的成年人通过电话完成了四次24小时饮食召回(24-HDR)，随后完成了一次自我管理的FFQ。比较了从24-HDRs和FFQ中获得的能量和营养估计值(蛋白质、碳水化合物、纤维、脂肪、维生素A、胡萝卜素、维生素D和钙)。使用皮尔逊相关系数、交叉分类法和Bland-Altman曲线图对数据进行分析。除男性蛋白质外，24-HDR的平均营养素摄入量均低于FFQ。性别和能量调整后的衰减皮尔逊相关系数在0.13到0.61之间。除男性的蛋白质外，所有的相关性与p <； 均有统计学意义。交叉分类分析显示，当比较FFQ和24-HDR的数据时，平均而言，74%的女性和78%的男性被归入相同或相邻的营养摄入量的四分之一。Bland-Altman曲线图显示，在平均摄入量范围内，两种仪器的给药之间没有严重的系统性偏差。这份包含169个条目的FFQ是专门为成人NL人群开发的，具有中等的相对效度，因此可以用于评估NL普通成年人的食物摄入量的研究。这个工具可以用来将个人的能量和营养摄入量分成四分位数，这在检查饮食和慢性病之间的关系时很有用。
The Food- Frequency Questionnaire (FFQ) is a dietary assessment tool frequently used in large-scale nutritional epidemiology studies. The goal of the present study is to validate a self-administered version of the Hawaii FFQ modified for use in the general adult population of Newfoundland and Labrador (NL). Over a one year period, 195 randomly selected adults completed four 24-hour dietary recalls (24-HDRs) by telephone and one subsequent self-administered FFQ. Estimates of energy and nutrients derived from the 24-HDRs and FFQs were compared (protein, carbohydrate, fibre, fat, vitamin A, carotene, vitamin D, and calcium). Data were analyzed using the Pearson’s correlation coefficients, cross-classification method, and Bland–Altman plots. The mean nutrient intake values of the 24-HDRs were lower than those of the FFQs, except for protein in men. Sex and energy-adjusted de-attenuated Pearson correlation coefficients for each nutrient varied from 0.13 to 0.61. Except for protein in men, all correlations were statistically significant with p < 0.05. Cross-classification analysis revealed that on average, 74% women and 78% men were classified in the same or adjacent quartile of nutrient intake when comparing data from the FFQ and 24-HDRs. Bland–Altman plots showed no serious systematic bias between the administration of the two instruments over the range of mean intakes. This 169-item FFQ developed specifically for the adult NL population had moderate relative validity and therefore can be used in studies to assess food consumption in the general adult population of NL. This tool can be used to classify individual energy and nutrient intakes into quartiles, which is useful in examining relationships between diet and chronic disease.
