Validity and Reproducibility of a Food Frequency Questionnaire for Estimating Macro- and Micronutrient Intakes Among Pregnant Women in Jordan.
Journal of the American College of Nutrition 2019 April 6
OBJECTIVES: Assessing the relationship between maternal diet and pregnancy outcomes is a crucial issue that requires valid dietary assessment tools in this critical period. This study aimed to develop and assess the validity and reproducibility of a culture-specific quantitative food frequency questionnaire (QFFQ) to evaluate the dietary intake of macro- and micronutrients from food in a sample of Jordanian pregnant women.
METHODS: A QFFQ was validated against three repeated 24-hour dietary recalls (24-hr recalls). The QFFQ was administered twice one month apart. A total of 131 Jordanian pregnant women participated in the validation study. Thirty women took part in the reproducibility phase, which was repeated in a time frame of one month.
RESULTS: The intra-class correlation coefficients of QFFQ1 and QFFQ2 for energy were 0.79 and for macronutrients ranged from -0.27 for insoluble fiber to 0.81 for dietary fiber, indicating adequate (0.51) reproducibility. The intra-class correlation coefficients between two QFFQs for micronutrients ranged from 0.19 for selenium to 0.85 for vitamin C. The average of correlation coefficient was 0.58 for micronutrients. Energy-adjusted and de-attenuated Pearson correlation coefficients between QFFQ1 and 24-hr dietary recall for macronutrients ranged from 0.13 for soluble fiber and trans fat to 0.90 for cholesterol and for micronutrients from 0.01 for sodium to 0.78 for magnesium.
CONCLUSIONS: The newly developed QFFQ could facilitate the assessment of the nutrient intake among Jordanian pregnant women. Using this QFFQ will help in evaluating the nutritional status of pregnant women, aiming at improving maternal and newborn health.
