OBJECTIVE To evaluate the reproducibility and validity of a food frequency questionnaire (FFQ) developed to investigate the relationship between dietary factors and diseases in the adult Chinese population in East China. METHODS A total of 78 males and 129 females aged 30-75 years completed four inconsecutive 24-hour dietary recalls (24-HRs, served as a reference method) and two FFQs (FFQ1 an...
Rice is commonly consumed in the Philippines; however the contribution of other foods to the diet is not well defined. Our aim was to determine the nutrient intake and food group intake of Philippine nuns and compare their intakes to the current estimated average requirements (EAR), and food-based recommendations, respectively, and assess any differences in nutrient adequacy and energy intakes ...
Empirical prediction models that weight food frequency questionnaire (FFQ) food items by their relation to nutrient biomarker concentrations may estimate nutrient exposure better than nutrient intakes derived from food composition databases. Carotenoids may especially benefit because contributing foods vary in bioavailability and assessment validity. Our objective was to develop empirical predi...
Presently, no national dietary guidelines--neither food- nor nutrient-based--exist for Austria. Usually, the recommendations of the German Society of Nutrition are used instead. The determination of national characteristics of nutritional behaviour and food consumption can reveal starting-points for the improvement of nutritional status in Austria. Seven-day weighed records (children and adoles...
Ulcerative colitis (UC) is an inflammatory bowel disease that causes gastrointestinal lesions, bleeding, diarrhoea and nutritional complications. Insufficient nutrient intake can additionally deteriorate nutritional status. The present cross-sectional study aimed to determine whether UC patients adhere to national dietary guidelines and to assess their dietary habits. An online questionnaire (n...
Food-based dietary guidelines (FBDG) aim to address the nutritional requirements at population level in order to prevent diseases and promote a healthy lifestyle. Diet quality indices can be used to assess the compliance with these FBDG. The present study aimed to investigate whether the newly developed Diet Quality Index for Adolescents (DQI-A) is a good surrogate measure for adherence to FBDG...
OBJECTIVE To evaluate the validity and reproducibility of a 122-item interviewer administered quantitative FFQ developed to determine food and nutrient intakes of adults in Botswana. DESIGN Relative validity of the FFQ was evaluated by comparing nutrient and food group intakes against four non-consecutive 24 h recalls administered over 12 months. The FFQ was repeated after 1 year to assess re...
BACKGROUND Competitive foods/beverages are those in school vending machines, school stores, snack bars, special sales, and items sold à la carte in the school cafeteria that compete with United States Department of Agriculture (USDA) meal program offerings. Grouping à la carte items with less nutritious items allowed in less regulated venues may obfuscate analysis of the school competitive food...
OBJECTIVE To describe an approach for assessing the prevalence of nutrient inadequacy in a group, using daily intake data and the new Estimated Average Requirement (EAR). DESIGN Observing the proportion of individuals in a group whose usual intake of a nutrient is below their requirement for the nutrient is not possible in general. We argue that this proportion can be well approximated in man...
