Many countries have launched national nutrition survey programs, and in some cases, survey data are publicly available. Use of national nutrition survey data allows assessment of nutrition and health status at a population level and provides evidence-based assessment to inform policy and regulations. For example, data from the National Health and Nutrition Examination Survey have been extensively used for the surveillance of the nutrition and health status of the U.S. population, and results have been used to support updates in policies such as the Dietary Guidelines for Americans. These publicly available data serve as a cost-effective resource for nutritional epidemiologists to explore various topics of interest.
The goal of this Research Topic is to share the latest findings from secondary analysis of national nutrition surveys with a special focus on how research findings may be translated to support the development of nutrition and public health policy.
We welcome submissions of original research on secondary analysis of data from publicly available nutrition surveys from the USA and other countries that may have policy implications. Focus areas include, but are not limited to:
• Associations between dietary intake and health outcomes
• Shifts in dietary pattern over time
• Racial-ethnic difference in dietary intake and nutrient adequacy
• Social determinants of dietary pattern and diet quality
• Food accessibility and affordability
• Evaluation of dietary intake before and after implementation of a nutrition policy
• Novel statistical methods
• Diet Pattern Modeling
