OBJECTIVE We aimed to assess the relative validity and reproducibility of a semi-quantitative FFQ in Puerto Rican adults. DESIGN Participants completed an FFQ, followed by a 6 d food record and a second administration of the FFQ, 30 d later. All nutrients were log transformed and adjusted for energy intake. Statistical analyses included correlations, paired t tests, cross-classification and B...

An interview administered food frequency questionnaire (FFQ) consisting of 75 food items was developed and calibrated against a four day weighed record (WR). The FFQ was also calibrated against a proxy for biomarker, the energy intake/basal metabolic rate ratio (EI/BMR). A total of 58 subjects (35 women, 23 men) aged between 19 and 76 years of Pakistani and Indian origin in Southampton, United ...

Due to the growing knowledge about the role of specific fatty acids in health and disease, dietary intake measurements of individual fatty acids or classes of fatty acids are becoming increasingly important. The objective of this study was to evaluate the ability of the Nambour FFQ to estimate intakes of specific fatty acids, particularly PUFA. The study population was a sub-sample of adult par...

OBJECTIVES This study assessed the reproducibility and relative validity of an eight-item self-administered food frequency questionnaire (FFQ) on intake of sugared snacks in Ugandan schoolchildren. A 5-day precoded food behaviour checklist (FBC) was used as validation criteria. Sociodemographic correlates of a sum frequency sugar score were explored. METHODS The study was conducted in Kampala...

BACKGROUND Guam is a US territory in the western Pacific with a diverse population that includes understudied ethnic groups such as Chamorros and Filipinos. A food frequency questionnaire (FFQ) to estimate dietary intake was needed to facilitate studies of diet and health among adults living in Guam. OBJECTIVE To develop and validate an FFQ to assess dietary intake over a 1-year period among ...

BACKGROUND A 50-item self-administered food frequency questionnaire (FFQ) was developed for French adults, to assess the intake of energy, 10 macronutrients, 11 vitamins, and 11 minerals, and to be used in the context of a medical consultation. OBJECTIVE To assess the repeatability and relative validity of this FFQ compared to a 7-day diet record (7-DR). DESIGN A total of 54 and 100 French ...

Hmong are one of the immigrant Asian subgroups with increasing rates of obesity, type 2 diabetes and CVD. Despite their population growth in the USA and declining health status, no research has investigated the appropriateness of dietary assessment measures, including FFQ and 24 h dietary recalls among Hmong. The present study compared the nutrient information obtained through a 24 h dietary re...

BACKGROUND Revision of the national nutrient database in 2000 had a strong impact on the absolute level of estimated nutrient intake in dietary assessments. However, whether it influenced the ranking of individuals by estimated intake, a more important function in epidemiologic studies, has not been investigated. Here, we investigated the effect of this revision of the nutrient database on the ...

The nutrient and heterocyclic amine (HCA) intake of 165 healthy participants was assessed using a self-administered food frequency questionnaire (FFQ), which included a meat-cooking practices module. A database containing the HCA [2-amino-3,8-dimethylimadazo [4,5-f] quinoxaline (MeIQx) and 2-amino-1-methyl-6-phenylimadazo [4,5-b] pyridine (PhIP)] composition of various types of meat, cooked by ...

BACKGROUND Cardiovascular diseases are the major cause of death in Malaysia. Evidence shows that dietary fat intake is one of the important risk factors for cardiovascular disease. However, studies assessing the association of fatty acids and risk of cardiovascular diseases in Malaysia are scarce. Therefore, this study aimed to develop and validate a food frequency questionnaire (FFQ) assessing...
