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…
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…
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…

Bias in dietary-report instruments and its implications for nutritional epidemiology
Objective: To evaluate measurement error structure in dietary assessment instruments and to investigate its implications for nutritional studies, using urinary nitrogen excretion as a reference biomarker for protein intake. Design: The dietary assessment methods included different food-frequency questionnaires (FFQs) and such conventional dietary-report reference instruments as a series of 24-hour recalls, 4-day weighed food records or 7-day diar…
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…
Time-to-Event Analysis of Longitudinal Follow-up of a Survey
Following individuals sampled in a large-scale health survey for the development of diseases and/or death offers the opportunity to assess the prognostic significance of various risk factors. The proportional hazards regression model, which allows for the control of covariates, is frequently used for the analysis of such data. The authors discuss the appropriate time-scale for such regression models, and they recommend that age rather than time s…
