Despite the increasing use of dietary patterns (DP) to study diet and health outcomes, relatively few studies have examined the reliability of DP using different dietary assessment methods. Reduced-rank regression (RRR) is an emerging statistical method that incorporates a priori information to characterise DP related to specific outcomes of interest. The aim of the present study was to compare...

The diet quality index (DQI) for preschool children is a new index developed to reflect compliance with four main food-based dietary guidelines for preschool children in Flanders. The present study investigates: (1) the validity of this index by comparing DQI scores for preschool children with nutrient intakes, both of which were derived from 3 d estimated diet records; (2) the reproducibility ...

OBJECTIVE The aim of the present study was to assess the concurrent and construct validity of two diet-quality indices, a modified Mediterranean diet score (mMDS) and a Mediterranean-like diet score (MLDS) additionally incorporating unhealthy food choices, as determined by an FFQ. DESIGN A validation study assessing FFQ intake estimates compared with ten or more unannounced 24 h recalls. Pear...

BACKGROUND Widespread subclinical iodine insufficiency has recently been reported in Europe, based on urinary iodine using World Health Organization/Food and Agriculture Organization criteria, in particular among young women. Although urinary iodine concentration (UIC) is a useful measurement of the iodine status in a population, it does not provide an insight into the habitual iodine intake of...

OBJECTIVE Nitrate and nitrite are probable human carcinogens when ingested under conditions that increase the formation of N-nitroso compounds. There have been limited efforts to develop US databases of dietary nitrate and nitrite for standard FFQ. Here we describe the development of a dietary nitrate and nitrite database and its calibration. DESIGN We analysed data from a calibration study o...

In this paper we introduce a new scheduling system with decoupled delay bound and bandwidth allocation guarantees. It is based on an existing efficient fair scheduler, Frame-based Fair Queueing (FFQ)[1], and therefore inherits the fairness, simplicity and efficiency of that policy. We combine a slightly modified version of an FFQ scheduler with the link sharing concept using rate estimator modu...

This study was performed to evaluate the validity of the food frequency questionnaire (FFQ), which is being used at the Samsung Medical Center. In total, 305 (190 males and 115 females) participants consented and completed the 3-day diet records and FFQ. Age, gender and energy-adjusted and de-attenuated correlations ranged from 0.317 (polyunsaturated fatty acid) to 0.748 (carbohydrate) with a m...

BACKGROUND Dietary assessment methods are important tools for nutrition research. Online dietary assessment tools have the potential to become invaluable methods of assessing dietary intake because, compared with traditional methods, they have many advantages including the automatic storage of input data and the immediate generation of nutritional outputs. OBJECTIVE The aim of this study was ...

Traumatic events are commonly re-experienced by trauma survivors through nightmares and flashbacks. The current study examined the relative sensitivity and specificity of these two forms of re-experiencing trauma in female survivors of rape. The frequency of nightmares and flashbacks were assessed using the Nightmare Frequency Questionnaire (NFQ) and the Flashback Frequency Questionnaire (FFQ),...

OBJECTIVE Diet validation research was conducted to compare the respondents' reporting of dietary intake in a food frequency questionnaire (FFQ) with intake reported in food recalls. Because the population received annual salary increments that could modify food intake, diet validation studies (DVSs) were conducted during two time intervals. DESIGN A 99-item FFQ was administered by an intervi...
