This course will provide students with the foundational knowledge and skills necessary to complete their own analyses of data from the National Health and Nutrition Examination Survey (NHANES). NHANES is a continuous annual survey designed to assess the health and nutritional status of adults and children in the United States. The course is comprised of didactic presentations and a hands-on lab. The course will review the survey design and sampling; survey components (i.e., questionnaires, dietary data, laboratory data, and examination data); measurement; and navigation of data documentation. During the laboratory component, students will conduct an analysis of NHANES data that covers the following: 1) data acquisition and management (e.g., downloading the data; merging data from multiple data files), 2) combining data from multiple years, 3) use of weights (i.e., which weights to apply, creating weights for multiple survey cycles), 4) use of data from multiple survey components (e.g., combining questionnaire data with lab data), and 5) descriptive and multivariable analyses. Note that the purpose of the class is to provide hands-on, practical experience in conducting analyses of NHANES data. While the course will include a series of scripted labs, there will also be an opportunity for you to conduct an analysis of your own. The course will be taught in Stata, but students with proficiency in other statistical packages can work in other packages.
After completing this course, participants will be able to:
- Develop a working knowledge of NHANES design, sampling, data documentation, and data file structure
- Understand how to select and apply appropriate survey design variables (i.e., weights, strata, PSU)
- Download, merge, recode, and conduct basic analyses of NHANES data
- Identify resources available to support further analyses
Prerequisite knowledge: Basic working knowledge of Stata or intermediate experience with another statistical software is required for this course.
