Validity and Reliability of Food Frequency Questionnaire in Age-Related Eye Disease Studies

What is it about?

The study aimed to assess the validity and reliability of the Food Frequency Questionnaire (FFQ) in determining the dietary intake of antioxidant nutrients in relation to Age-Related Eye Diseases (AREDs). The FFQ was found to be a suitable tool for determining the dietary intake levels of antioxidant nutrients in the Turkish population. The FFQ was tested for reliability and validity by comparing it to the Dietary Records (DR). The results showed that the FFQ was reliable and accurate in determining the intake of antioxidant nutrients such as omega 3, Vitamin A, total carotene, Vitamin C, and zinc. The study also found that individuals aged 50 and above, particularly those with AMD, had a higher prevalence of risk factors such as smoking and lower education levels.

Why is it important?

This study is important for several reasons: It helps to determine the dietary intake levels of antioxidant nutrients in the Turkish population, which can potentially help in reducing the risk of Age-Related Macular Degeneration (AMD) and other related eye diseases. The adaptation of the AREDS FFQ to Turkish adults offers a more efficient method for determining antioxidant nutrient intake compared to the Dietary Records (DRs) used in previous studies, as the FFQ is faster to complete. The results can be useful in epidemiological studies related to AMD and other age-related eye diseases. Key Takeaways: 1. The AREDS FFQ, adapted to Turkish adults, is a suitable tool for determining the dietary intake levels of antioxidant nutrients. 2. The concordance between the FFQ and DR was found to be moderately compatible for omega 3, Vitamin A, total carotene, Vitamin C, and zinc intake. 3. The study emphasizes the importance of determining the relationship between antioxidant nutrients and AMD, which can potentially lead to interventions that reduce the risk of AMD development and progression.
