Finding Datasets for Secondary Analysis


The National Health and Nutrition Examination Survey (NHANES) is a major initiative of the National Center for Health Statistics (NCHS). It is designed to provide comprehensive data on the health and nutritional status of adults and children in the United States. Thousands of studies have been published using NHANES data.

On July 22, 2020, the Welch Medical Library and the Johns Hopkins Bloomberg School of Public Health sponsored a symposium on the NHANES data: "Unlocking NHANES: Content, Applications, and Analysis of the National Health and Nutrition Examination Survey Data" . 

 At the symposium, five speakers have presented on various topics ranging from the scope of the data, its potential for use, limitations, challenges, and proposed solutions. It was attended by over 200 people.
