National Longitudinal Study of Adolescent to Adult Health (Add Health) Wave 6 (U01 Clinical Trial Not Allowed) | RFA AG 21 008

Opportunity Information: Apply for RFA AG 21 008

The National Longitudinal Study of Adolescent to Adult Health (Add Health) Wave 6 funding opportunity (RFA-AG-21-008) is a National Institutes of Health (NIH) announcement seeking a cooperative agreement (U01; clinical trial not allowed) to carry Add Health into its next 5-year cycle through a sixth wave of data collection. Add Health is a long-running, nationally representative cohort that began in 1994-1995 with adolescents in grades 7-12 (roughly ages 12-19), primarily individuals born between 1976 and 1982. Those same participants are now moving into middle age, which makes this next wave especially valuable for understanding how early-life and young adult experiences shape health, functioning, and inequality later on.

The core purpose of Wave VI is to re-contact and re-interview cohort members and to capture new, midlife-relevant data at scale while maintaining the study's rigorous longitudinal design. The FOA calls for a mixed-mode approach that combines web-based and in-person interviewing, backed by strong, proactive efforts to minimize attrition. A major emphasis is placed on aggressive non-response follow-up to protect representativeness over time and to reduce bias that can emerge when harder-to-reach participants drop out. The announcement also highlights targeted oversamples of race/ethnic-minority and low-socioeconomic-status participants to strengthen the study's ability to analyze health disparities and the social determinants that drive them.

A second major pillar of Wave VI is an in-home health examination component, including venous blood collection. This expands the study beyond self-reported survey data and basic measures, allowing the project to generate objective biological indicators of disease risk and health status. The FOA explicitly includes the expectation that collected biological specimens will be assayed for biomarkers of disease, enabling analyses that connect social exposures and life-course experiences with physiological pathways and emerging chronic conditions in midlife. In addition, specimens are expected to be stored for future scientific use, supporting downstream research as new questions and laboratory methods develop.

Wave VI is also intended to deepen measurement in content areas that become increasingly important in midlife and later-life research. The FOA points to domains such as cumulative stress, discrimination, work-life balance, and caregiving, all of which can affect health trajectories, mental health, economic stability, and disparities. In practical terms, this means applicants are expected to propose enhancements that capture how sustained exposures and responsibilities accumulate over decades and how these experiences differ across social groups, potentially explaining gaps in aging outcomes.

Beyond data collection, the opportunity places heavy responsibility on data stewardship and community value. Awardees are expected to clean and document the Wave VI data thoroughly, disseminate it to the broader scientific community, and archive both data and biological specimens in ways that preserve long-term accessibility and usefulness. The FOA also stresses actively promoting the Wave VI data to researchers, particularly to support aging research, which implies not just depositing files but producing high-quality documentation, user guidance, and well-managed access processes that help investigators use the resource responsibly and efficiently.

Administratively, this is a discretionary grant opportunity using a cooperative agreement mechanism, meaning NIH will likely have substantial programmatic involvement during the project compared with a typical research project grant. The CFDA numbers listed for the opportunity are 93.275, 93.307, 93.865, and 93.866. The award ceiling is $4,500,000, and the original closing date was May 18, 2020, with the FOA created on February 26, 2020. While the text does not specify the exact number of expected awards in the provided excerpt, the structure and scope indicate support for a large, centralized effort capable of conducting national follow-up, field operations, biospecimen handling, laboratory assays, and public-use dissemination.

Eligibility is broad across U.S.-based organizations and governmental entities, including state, county, and local governments; special districts; independent school districts; public and private institutions of higher education; federally recognized Native American tribal governments; tribal organizations; public housing authorities; nonprofits (both 501(c)(3) and non-501(c)(3)); for-profit organizations (other than small businesses); and small businesses. The FOA also explicitly notes additional eligible applicant types such as Alaska Native and Native Hawaiian Serving Institutions, AANAPISISs, Hispanic-serving institutions, Historically Black Colleges and Universities, Tribally Controlled Colleges and Universities, faith-based or community-based organizations, regional organizations, eligible federal agencies, and U.S. territories or possessions. At the same time, non-domestic (non-U.S.) entities and non-domestic components of U.S. organizations are not eligible to apply; however, foreign components, as NIH defines them in its Grants Policy Statement, are allowed, which typically means discrete, justified international elements can participate under a U.S.-led application.

In short, this FOA is designed to keep Add Health scientifically current and methodologically strong as the cohort enters midlife, pairing modern mixed-mode surveys with in-home exams and blood-based biomarkers, strengthening representation through intensive follow-up and oversampling, and delivering a well-documented, widely shared dataset and biorepository that can power the next generation of research on aging, health, and disparities.
