The present study aimed to perform the validity and reliability study of the Food Frequency Questionnaire (FFQ) on the frequency of foods rich in antioxidant nutrients and used in Age-Related Eye Diseases (AREDs). In the first interview of the study, the first application of FFQ was carried out, and blank forms of Dietary Records (DRs) were given. For the validity of the FFQ, a total of 12 d (3 days * 4 weeks) of DR were taken. For the reliability of the FFQ, a test-retest application was made with an interval of 4 weeks. The daily intake means of antioxidant nutrients, omega 3 and total antioxidant capacity data obtained from both the FFQ and DR were calculated, and the concordance between the two methods was evaluated with the Pearson Correlation Coefficient (PCC) and Bland-Altman graphs. The present study was carried out at Ege University İzmir/Turkey, Department of Ophthalmology, Retina Unit. The study was conducted with individuals aged ≥50 years who suffered from Age-Related Macular Degeneration ( 100, 72⋅0 ± 8⋅03 years). The values obtained from the test-retest applications for FFQ reliability were the same. The nutrient intake means obtained from the FFQ were similar or significantly higher than DR ( < 0⋅05). In the Bland-Altman graphical approach, the nutrient data were within the limits of agreement, and the PCCs between the two methods were moderately related. Considered together, this FFQ is a suitable tool for determining the dietary intakes of antioxidant nutrients in the Turkish population.
本研究旨在对富含抗氧化营养素并用于年龄相关性眼病（AREDs）的食物频率问卷（FFQ）进行有效性和可靠性研究。在研究的第一次访谈中，首次应用了 FFQ，并提供了膳食记录（DR）的空白表格。为了验证 FFQ 的有效性，共进行了 12 天（3 天*4 周）的 DR。为了验证 FFQ 的可靠性，采用了间隔 4 周的测试-重测应用。从 FFQ 和 DR 获得的抗氧化营养素、ω-3 和总抗氧化能力数据的每日摄入量均值，并通过 Pearson 相关系数（PCC）和 Bland-Altman 图评估两种方法之间的一致性。本研究在土耳其伊兹密尔的爱琴海大学眼科、视网膜科进行。该研究对象为年龄≥50 岁且患有年龄相关性黄斑变性的个体（100 人，72.0±8.03 岁）。FFQ 可靠性测试-重测应用获得的营养素摄入均值相同。FFQ 获得的营养素摄入量均值与 DR 相似或明显更高（<0.05）。在 Bland-Altman 图形方法中，营养素数据在一致性范围内，两种方法之间的 PCC 呈中度相关。综合考虑，这种 FFQ 是一种适合确定土耳其人群抗氧化营养素膳食摄入量的工具。
