NIH-AARP Diet and Health Secondary Research Study Based on OH95CN025 Data
NCT04750915 · View on ClinicalTrials.gov ↗
Study Summary
Background: The NIH and the American Association of Retired Persons (AARP) conducted a Diet and Health Study. It studied the links between diet, cancer, and cause of death in a group of middle-aged people in the U.S. Researchers want to learn more about how diet and lifestyle can affect cancer and mortality. Objective: To clarify links between diet, lifestyle, cancer, death, and chronic diseases. Eligibility: AARP members ages 50 to 71 who took part in study #OH95CN025 and lived in California, Florida, Pennsylvania, New Jersey, North Carolina, Louisiana, Atlanta, or Detroit in 1995 1996. Design: This study will use existing data and samples. Participants will not be contacted. Participants personal data, like name, date of birth, and address, will be used. This data will be kept private. Their data and samples will get a unique ID. Data from other follow-up studies will be used. Cancer outcome data will be obtained from the 8 sample areas. Many participants have moved to Arizona, Nevada, and Texas. Data will be obtained from those states as well. Cause of death and date of death will be obtained from the National Death Index. Cheek swab samples were gathered from 2004 to 2005. They will be used to study the oral microbiome. The University of Washington (UW) will be added as a study site. UW will study air pollution. The process of linking with the Virtual Pooled Registry Cancer Linkage System will be explored. It uses one system. Right now, 11 state systems are used to get and link data. Paper records will be stored in locked file rooms. Electronic data will be stored on secure servers.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04750915
The ClinicalTrials.gov registry entry for NCT04750915 describes a study currently listed as active not recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 566,398 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Cancer Institute (NCI), which has 2,390 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Cancer appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04750915 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
