On May 23, 2019, NCCOR hosted a Connect & Explore webinar to discuss the findings in a recent publication from the U.S. Department of Agriculture Economic Research Service called “Linking USDA Nutrition Databases to IRI Household-Based and Store-Based Scanner Data.” USDA researchers created a purchase-to-plate “crosswalk”—linking USDA data and household retail scanner data—to measure the overall healthfulness of American’s food-at-home (FAH) purchases. Results show that improvements in the healthfulness of Americans’ FAH purchases are needed to comply with federal dietary guidance. The speaker is Andrea Carlson, PhD, MS,an economist in the Food Markets Branch of the Food Economics Division.
In this Methods: Mind the Gap presentation, Dr. Tucker discusses the approaches to dietary assessment for estimating usual intake for the purpose of relating intake of nutrients, foods, and food patterns to chronic health conditions such as diabetes, heart disease, stroke, cognitive decline, bone loss, and others.

These 12 webinars are intended for nutritionists, epidemiologists, statisticians, graduate students, and others with an interest in measurement error in dietary intake data. The goal of the webinar series is to provide participants with an understanding of:
- The sources and magnitudes of dietary measurement errors
- How measurement error may affect estimates of usual dietary intake distributions
- How measurement error may affect analyses of diet–health relationships
- How the effects of measurement error may be mitigated.
These modules are designed to complement the Measures Registry and Measures Registry User Guides and assist researchers and practitioners with choosing the best measures across the four domains of the Measures Registry: individual diet, food environment, individual physical activity and physical activity environment.
This webinar describes the purpose and use of the latest mobile-friendly version of the Automated Self-Administered 24-Hour Recall/Record System (ASA24). The tool is freely available to researchers, clinicians, and educators for dietary intake collection. Speakers describe the background of the tool, its evaluation, and best practices for its use.
NCI has developed two online resources for use in selecting instruments for various research questions: the Dietary Assessment Primer and the Measures Registry. Both are designed to provide knowledge transfer and facilitate adoption of best assessment practices. This webinar describes each of these resources with a focus on how we can minimize measurement error by opening up access to the best assessment methods.
Part one of the two-part series, Measuring Success in Low-Income Nutrition Education and Obesity Prevention Programs, explores how to use the framework to evaluate nutrition education and obesity prevention programs.
Part two, Strategies and Tools for Measuring the Priority Indicators, highlights the seven SNAP-Ed priority indicators from the Evaluation Framework and shares practical examples of measuring healthy eating behaviors, physical activity, and reduced sedentary behaviors in low-income children and families.
