ENAR DataFest Submission

We are seeking ENAR Student members, who are degree candidates at an accredited institution in any term during 2023-24 academic year to participate in the inaugural ENAR 2024 DataFest event. Student teams can include 1-4 members and will work with a curated dataset from the US National Health and Nutrition Examination Survey (NHANES) to answer an important scientific question related to blood pressure control.

Up to six submissions will be selected to give 5-minute presentations at a February web-ENAR. Among these, the top four teams will receive individual team member certificates, a joint cash prize of $500, and an invitation for a 20-minute presentation as part of the ENAR DataFest Invited Session. The team with the most outstanding final presentation will receive the ENAR DataFest Award, which includes an additional $500 prize.


To be eligible, a student team must include 1-4 individuals who are all ENAR members, degree candidates at an accredited institution in any term during 2023-24 academic year, and able to present their project during both a February web-ENAR and the ENAR Spring Meeting, March 10-13, 2024, in Baltimore, Maryland. Teams will work with a curated dataset from the US National Health and Nutrition Examination Survey (NHANES) to answer an important scientific question related to blood pressure control. Teams will submit a GitHub repository that includes (1) a maximum 5-page report with up to 2 figures and 2 tables, (2) a 5-minute video presentation, and (3) associated reproducible code base. The statistical analysis should consider a problem, issue or policy question relevant to the problem statement (see below).

All required materials for ENAR DataFest must be received by the ENAR Business Office, including the electronic submission of the manuscript and video presentation through, by 11:59 p.m. ET January 17th, 2024. Only complete submissions that meet the eligibility requirements, follow the described guidelines, and are received by January 17th will be considered.

DataFest Project Summary

Problem statement: Controlling blood pressure (BP) reduces the risk for cardiovascular disease. However, the prevalence of BP control (i.e., systolic BP < 140 and diastolic BP < 90) among US adults with hypertension has decreased since 2013. We invite teams to analyze publicly available data from US adults to help identify potential causes or correlates of worsening BP control among US adults with hypertension over the past decade, as this may allow for development of effective interventions to help control BP and prevent cardiovascular disease.

Description: Data from the US National Health and Nutrition Examination Survey (NHANES) containing information about demographics, blood pressure levels, hypertension status, antihypertensive medication usage, and co-morbidities for a sample of 59,799 noninstitutionalized US adults collected between 1999 and 2020.

Availability: The data can be downloaded from GitHub or accessed via the cardioStatsUSA R package. For both the file and information about the R package, see

Accessing additional NHANES data: We highly recommend downloading additional NHANES data from, and merging it with the data linked above, but this is not a requirement.

Documentation: For a detailed description of all variables in the data, see

Interactive exploration: A shiny application has been created to help explore hypertension statistics for US adults using these data. The application is available here:

For more details on the data and the shiny application, see the supporting paper
