The Dietary Screener Questionnaire was developed in collaboration with the Risk Factor Monitoring and Methods Branch (RFMMB), of the National Cancer Institute, National Institutes of Health for inclusion in the NHANES 2009-2010 survey. The questionnaire was designed to collect information on participants' intake of fruits and vegetables, fiber, added sugar, dairy/calcium, whole grains, red meat, and processed meat.
The Dietary Screener Questionnaire was included in the NHANES 2009-2010 in order to gather data for use in calibrating screeners. Screeners are shorter and less detailed than a total dietary assessment, and therefore, quantitative accuracy is sacrificed. The Dietary Screener was calibrated against the more precise 24-hour recall in order to ensure that the screener is providing the most accurate estimates possible. The calibration is carried out using a set of scoring algorithms developed for each of the components of the Dietary Screener Questionnaire. The scoring algorithms are provided by the RFMMB website to convert screener responses to estimates of dietary intake for components such as fruits and vegetables (cups), fiber (g), added sugars (tsp), calcium (mg), dairy (cup equivalents), and whole grains (ounce equivalents).
A SAS program is available on the RFMMB website to: 1) convert frequency data to daily frequency, 2) identify extreme exposure values, 3) classify cereal data, and 4) develop scoring algorithms.
The scoring algorithms enable researchers using the Dietary Screener Questionnaire in their own studies to improve the accuracy of estimates of dietary factors assessed. Researchers also will be able to compare their results to calibrated national estimates from NHANES.
All survey participants ages 2-69 years were eligible.
For respondents ages 2-11 years, the questions were asked, in the home, by trained interviewers using the Computer-Assisted Personal Interviewing (CAPI) system. A proxy provided information for survey participants. Hand cards showing response categories were also used for some question.
For respondents ages 12-69 years, the questions were asked at the Mobile Examination Center (MEC) during the MEC Interview, by trained interviewers using the Computer-Assisted Personal Interviewing (CAPI) system. Hand cards showing response categories were also used for some questions.
The CAPI system is programmed with built-in consistency checks to reduce data entry errors. CAPI also uses online help screens to assist interviewers in defining key terms used in the questionnaire.
During the 2009-2010 data collection cycle, periodic quality control checks were performed on the Dietary Screener questionnaire data being collected. Interviewer specific feedback and retraining was performed as appropriate.
Participants were asked the name of up to two cereals that they usually ate during the past 30 days. These cereal names were matched to cereals and codes from the United States Department of Agriculture's (USDA) Food and Nutrient Database for Dietary Studies, 5.0 (FNDDS 5.0) (http://www.ars.usda.gov/ba/bhnrc/fsrg). The underlying nutrient values for FNDDS 5.0 were based on values in the USDA National Nutrient Database for Standard Reference, release 24, produced by USDA's Nutrient Data Lab (http://www.ars.usda.gov/nutrientdata). FNDDS values are updated for every 2-year WWEIA, NHANES release cycle. FNDDS 5.0 corresponds with WWEIA 2009-2010. There were two cereals reported that were not in FNDDS 5.0, and therefore needed to be matched to from FNDDS 4.0, which is the previous version of the database.
The NHANES full sample 2-Year Interview Weights (WTINT2YR) should be used to analyze the 2009-2010 DTQ data for respondents ages 2-11 years old. Although these data were collected as part of the household questionnaire, if they are merged with the MEC exam data, exam sample weights should be used for the analyses.
The NHANES full sample 2-Year MEC Exam Weights (WTMEC2YR) should be used to analyze the 2009-2010 DTQ data for respondents ages 12-69 years old.
Please refer to the NHANES Analytic Guidelines and the on-line NHANES Tutorial for further details on the use of sample weights and other analytic issues.
