Validity and Reproducibility of a Food Frequency Questionnaire to Assess Nutrients Intake of Pregnant Women in the South-East of Spain. Nutrients. 2021 Aug 30;13(9):3032http://hdl.handle.net/10668/4318Proper nutrition during pregnancy is pivotal to maintain good health for the child and the mother. This study evaluates the reproducibility and validity of a food frequency questionnaire (FFQ) designed to assess nutrient intake during pregnancy in the GENEIDA (Genetics, Early life Environmental Exposures and Infant Development in Andalusia) prospective birth cohort study. In addition, the nutrient intake was estimated and then compared with European guidelines and other studies. Diet information was collected from 690 pregnant women using a FFQ administered at two periods of pregnancy (used for the reproducibility study) and 24-h dietary recall (for the validity study). Statistical approaches included Spearman's correlation coefficient and percentage agreement, classifying women into the same or adjacent quintiles to assess reproducibility, and limits of agreement (LoA) to evaluate validity. In the study of reproducibility, significant correlations for nutrients adjusted for total energy had an average of 0.417. Moreover, the percentage of subjects classified in the same quintile for nutrient intakes were above 66%. In the validation study, the significant correlation for nutrients adjusted for total energy had an average of 0.272. Nevertheless, the percentage of results in the LoA was above 94%. Our results were similar to other studies suggesting that the FFQ used is a valid tool of collect dietary intakes for South-East Spanish pregnant women.enAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/Pregnant womenNutritionIntakeFood frequency questionnaire24-h dietary recallsSpainMujeres embarazadasNutrición maternaEvaluación nutricionalIngesta diaria recomendadaEncuestas nutricionalesEspañaMedical Subject Headings::Persons::Persons::Age Groups::AdultMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Epidemiologic Studies::Cohort StudiesMedical Subject Headings::Phenomena and Processes::Physiological Phenomena::Nutritional Physiological Phenomena::DietMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Data Collection::Health Surveys::Nutrition Surveys::Diet SurveysMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Phenomena and Processes::Reproductive and Urinary Physiological Phenomena::Reproductive Physiological Phenomena::Reproductive Physiological Processes::Reproduction::PregnancyMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Epidemiologic Studies::Cohort Studies::Longitudinal Studies::Prospective StudiesMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Research Design::Reproducibility of ResultsMedical Subject Headings::Geographical Locations::Geographic Locations::Europe::SpainMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Data Collection::QuestionnairesMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Data Collection::Nutrition AssessmentMedical Subject Headings::Persons::Persons::Age Groups::ChildMedical Subject Headings::Persons::Persons::Women::Pregnant WomenMedical Subject Headings::Psychiatry and Psychology::Behavior and Behavior Mechanisms::Human Development::Child DevelopmentMedical Subject Headings::Persons::Persons::Parents::MothersMedical Subject Headings::Phenomena and Processes::Physiological Phenomena::Nutritional Physiological Phenomena::Maternal Nutritional Physiological Phenomena::Prenatal Nutritional Physiological PhenomenaMedical Subject Headings::Phenomena and Processes::Digestive System and Oral Physiological Phenomena::Digestive System Physiological Phenomena::Digestive System Processes::EatingMedical Subject Headings::Health Care::Environment and Public Health::Public Health::Environmental Pollution::Environmental Exposureresearch article34578909Acceso abierto10.3390/nu130930322072-6643PMC8467594
