Dietary assessment toolkits
Objective A wide variety of methods are available to assess dietary intake, each one with different strengths and weaknesses. Researchers face multiple challenges when diet and nutrition need to be accurately assessed, particularly in the selection of the most appropriate dietary assessment method for their study. The goal of the current collaborative work is to present a collection of available resources for dietary assessment implementation. De…

Update of the Healthy Eating Index
Using national dietary intake data to evaluate and adapt the US Diet History Questionnaire
Objective To evaluate the Canadian Diet History Questionnaire I (C-DHQ I) food list and to adapt the US DHQ II for Canada using Canadian dietary survey data. Design Twenty-four-hour dietary recalls reported by adults in a national Canadian survey were analysed to create a food list corresponding to C-DHQ I food questions. The percentage contribution of the food list to the total survey intake of seventeen nutrients was used as the criterion to ev…
Development and calibration of a dietary nitrate and nitrite database in the NIH–Aarp Diet and Health Study
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 of 1942 members of the NIH–AARP (NIH–AARP, National Ins…
Addressing Current Criticism Regarding the Value of Self-Report Dietary Data
The Automated Self-Administered 24-Hour Dietary Recall (ASA24)
Strength of the relationships between three self-reported dietary intake instruments and serum carotenoids
Objective To assess the strength of the relationships between serum carotenoids and three self-reported dietary intake instruments often used to characterize carotenoid intake in studies of diet and disease. Design Participants completed a Diet History Questionnaire (DHQ), two 24 h dietary recalls (24HR), a fruit and vegetable screener and a fasting blood draw. We derived dietary intake estimates of α-carotene, β-carotene, cryptoxanthin, lutein, …
Validating an FFQ for intake of episodically consumed foods
Objective To develop a method to validate an FFQ for reported intake of episodically consumed foods when the reference instrument measures short-term intake, and to apply the method in a large prospective cohort. Design The FFQ was evaluated in a sub-study of cohort participants who, in addition to the questionnaire, were asked to complete two non-consecutive 24 h dietary recalls (24HR). FFQ-reported intakes of twenty-nine food groups were analys…
Children’s accuracy of portion size estimation using digital food images
Objective To test the effect of image size and presence of size cues on the accuracy of portion size estimation by children. Design Children were randomly assigned to seeing images with or without food size cues (utensils and checked tablecloth) and were presented with sixteen food models (foods commonly eaten by children) in varying portion sizes, one at a time. They estimated each food model’s portion size by selecting a digital food image. The…
Americans Do Not Meet Federal Dietary Recommendations
Environment And Genetics in Lung cancer Etiology (Eagle) study
EAGLE is a new population-based case-control study that explores the full spectrum of lung cancer etiology, from smoking addiction to lung cancer outcome, through examination of epidemiological, molecular, and clinical data. We have provided a detailed description of the study design, field activities, management, and opportunities for research following this integrative approach, which allows a sharper and more comprehensive vision of the comple…
Performance of a food-frequency questionnaire in the US NIH–Aarp (National Institutes of Health–American Association of Retired Persons) Diet and Health Study
Objective We evaluated the performance of the food-frequency questionnaire (FFQ) administered to participants in the US NIH–AARP (National Institutes of Health–American Association of Retired Persons) Diet and Health Study, a cohort of 566 404 persons living in the USA and aged 50–71 years at baseline in 1995. Design The 124-item FFQ was evaluated within a measurement error model using two non-consecutive 24-hour dietary recalls (24HRs) as the re…
Adaptation and evaluation of the National Cancer Institute's Diet History Questionnaire and nutrient database for Canadian populations
Background and objective Despite assumed similarities in Canadian and US dietary habits, some differences in food availability and nutrient fortification exist. Food-frequency questionnaires designed for the USA may therefore not provide the most accurate estimates of dietary intake in Canadian populations. Hence, we undertook to evaluate and modify the National Cancer Institute's Diet History Questionnaire (DHQ) and nutrient database. Methods Of…
A New Statistical Method for Estimating the Usual Intake of Episodically Consumed Foods with Application to Their Distribution
Statistical Methods for Estimating Usual Intake of Nutrients and Foods
Performance of a short tool to assess dietary intakes of fruits and vegetables, percentage energy from fat and fibre
Objectives: We describe the methods used to develop and score a 17-item ‘screener’ designed to estimate intake of fruit and vegetables, percentage energy from fat and fibre. The ability of this screener and a food-frequency questionnaire (FFQ) to measure these exposures is evaluated. Design: Using US national food consumption data, stepwise multiple regression was used to identify the foods to be included on the instrument; multiple regression an…
Using Intake Biomarkers to Evaluate the Extent of Dietary Misreporting in a Large Sample of Adults
This paper describes the Observing Protein and Energy Nutrition (OPEN) Study, conducted from September 1999 to March 2000. The purpose of the study was to assess dietary measurement error using two self-reported dietary instruments-the food frequency questionnaire (FFQ) and the 24-hour dietary recall (24HR)-and unbiased biomarkers of energy and protein intakes: doubly labeled water and urinary nitrogen. Participants were 484 men and women aged 40…
Fruit and Vegetable Assessment
Comparative Validation of the Block, Willett, and National Cancer Institute Food Frequency Questionnaires
Researchers at the National Cancer Institute developed a new cognitively based food frequency questionnaire (FFQ), the Diet History Questionnaire (DHQ). The Eating at America's Table Study sought to validate and compare the DHQ with the Block and Willett FFQs. Of 1,640 men and women recruited to participate from a nationally representative sample in 1997, 1,301 completed four telephone 24-hour recalls, one in each season. Participants were random…
US adults' fruit and vegetable intakes, 1989 to 1991
OBJECTIVES. This study provides revised baseline data for the Healthy People 2000 objective related to fruit and vegetable intakes, accounting for fruits and vegetable intakes, accounting for fruits and vegetables from all sources and measuring servings in a manner consistent with current dietary guidance. METHODS. Dietary data from 8181 adults in the US Department of Agriculture's 1989-1991 Continuing Surveys of Food Intakes by Individuals were …
Fruit and vegetable intake among adults in 16 states
A brief food frequency questionnaire was used to assess daily fruit and vegetable consumption among 23,699 adults in 16 US states sampled in a random-digit dialing telephone survey. Men consumed fewer servings per day (3.3) than did women (3.7). Only 20% of the population consumed the recommended 5 or more daily servings. Intakes varied somewhat by state and were lower among the young and the less educated. Efforts are needed to improve fruit and…
US dietary patterns associated with fat intake
OBJECTIVES. This research used food frequency data to investigate dietary patterns associated with fat intake. METHODS. Data from the 1987 National Health Interview Survey of 20,143 adults were used to determine correlations between fat (adjusted for kilocalories) and both nutrient and food group intakes. Median food and nutrient intakes were determined within quartiles of percentage of kilocalories from fat. RESULTS. Intakes of vegetables, fruit…
Fruit, vegetables, and cancer prevention
Approximately 200 studies that examined the relationship between fruit and vegetable intake and cancers of the lung, colon, breast, cervix, esophagus, oral cavity, stomach, bladder, pancreas, and ovary are reviewed. A statistically significant protective effect of fruit and vegetable consumption was found in 128 of 156 dietary studies in which results were expressed in terms of relative risk. For most cancer sites, persons with low fruit and vege…
Food and nutrient intake differences between smokers and non-smokers in the US
Data from the Second National Health and Nutrition Examination Survey were analyzed to determine food and nutrient intake differences between current smokers (also categorized as light, moderate, and heavy smokers) and non-smokers. Smokers in several age-race-sex categories have lower intakes of vitamin C, folate, fiber, and vitamin A than non-smokers, and intake tended to decrease as cigarette consumption increased, particularly for vitamin C, f…
