  • Validating an FFQ for intake of episodically consumed foods

    Open AccessDouglas Midthune, Arthur Schatzkin et al.ARTICLEPublic Health Nutrition2011

    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

    Open AccessFrances E Thompson, Victor Kipnis et al.ARTICLEPublic Health Nutrition2008

    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…

  • Overweight, Obesity, and Mortality in a Large Prospective Cohort of Persons 50 to 71 Years Old

    Kenneth Adams, Kenneth F Adams et al.ARTICLENew England Journal of Medicine2006

    BACKGROUND: Obesity, defined by a body-mass index (BMI) (the weight in kilograms divided by the square of the height in meters) of 30.0 or more, is associated with an increased risk of death, but the relation between overweight (a BMI of 25.0 to 29.9) and the risk of death has been questioned. METHODS: We prospectively examined BMI in relation to the risk of death from any cause in 527,265 U.S. men and women in the National Institutes of Health-A…

  • Performance of a short tool to assess dietary intakes of fruits and vegetables, percentage energy from fat and fibre

    Open AccessFrances E Thompson, Douglas Midthune et al.ARTICLEPublic Health Nutrition2004

    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…

  • Structure of Dietary Measurement Error

    Victor KipnisARTICLEAmerican Journal of Epidemiology2003

    Multiple-day food records or 24-hour dietary recalls (24HRs) are commonly used as "reference" instruments to calibrate food frequency questionnaires (FFQs) and to adjust findings from nutritional epidemiologic studies for measurement error. Correct adjustment requires that the errors in the adopted reference instrument be independent of those in the FFQ and of true intake. The authors report data from the Observing Protein and Energy Nutrition (O…

  • Bias in dietary-report instruments and its implications for nutritional epidemiology

    Open AccessVictor Kipnis, Douglas Midthune et al.ARTICLEPublic Health Nutrition2002

    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

    Open AccessAmy F Subar, Frances E Thompson et al.ARTICLEAmerican Journal of Epidemiology2001

    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…
