The objective of this study was to validate two interviewer-led food frequency questionnaires (FFQs) of very different lengths: a medium-length FFQ (medium-FFQ) of 36 items and a short-length FFQ (short-FFQ) of 18 items, intending to measure levels of intakes in a local population. Both FFQs were validated against intakes derived from a 3-day dietary record (3-day DR). Sixty-five non-diabetic adults with no known cardiovascular, renal or other systemic diseases were included. High correlation coefficients between the FFQ and the 3-day DR (0.45-0.73) were observed for energy intake, carbohydrates and lipid and protein intake. Bland-Altman plots showed good agreement between the methods. Low (0.26-0.37) correlation coefficients of the different nutrient intakes obtained with the short-FFQ and the 3-day DR were observed, with the exception of alcohol intake (rho = 0.49). This study showed promising evidence for the use of a medium-FFQ as a potentially useful tool for investigating the relationship between habitual diet and diseases in clinical and research settings.
本研究的目的是验证两份长度差异很大的由访谈者主导的食物频率问卷（FFQ）：一份包含36个条目的中等长度FFQ（中等FFQ）和一份包含18个条目的短长度FFQ（短FFQ），旨在测量当地人群的摄入量水平。两份FFQ均根据3天饮食记录（3天DR）得出的摄入量进行验证。纳入了65名无已知心血管、肾脏或其他系统性疾病的非糖尿病成年人。在能量摄入、碳水化合物、脂质和蛋白质摄入方面，观察到FFQ与3天DR之间具有较高的相关系数（0.45 - 0.73）。Bland-Altman图显示两种方法之间具有良好的一致性。除酒精摄入量外（rho = 0.49），观察到短FFQ与3天DR得出的不同营养素摄入量之间的相关系数较低（0.26 - 0.37）。本研究表明，有证据支持在临床和研究环境中，将中等FFQ作为研究习惯性饮食与疾病之间关系的潜在有用工具。
