Environmental Polymorphisms Registry Health and Exposures Survey
NCT01688986 · View on ClinicalTrials.gov ↗
Study Summary
The Environmental Polymorphisms Registry (EPR) Health and Exposure Survey is designed to gather health, family history of disease, environmental exposures and lifestyle data on adult EPR subjects. The EPR is a registry established to collect and store DNA samples from 20,000 volunteers from North Carolina and to serve as a resource to scientist investigating genotype-driven translational research of chronic conditions. Under this new protocol, we will administer a health and exposures survey to all EPR subjects. The information collected in the survey will be used to better characterize the EPR population thus making it more useful to NIEHS researchers. The survey contains approximately 200 questions. Data from the survey will help researchers develop hypotheses, design follow-up studies, and select appropriate subjects. The survey will be administered to EPR subjects using a modified version of the Dillman Total Design Method (TDM) for surveys. This method requires following specific time-dependent steps for survey administration that incorporate both self- and phone administration and other types of phone and mail contact. The goal of TDM is to maximize subject response rates.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01688986
The ClinicalTrials.gov registry entry for NCT01688986 describes a study currently listed as completed. 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 9,000 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Environmental Health Sciences (NIEHS), which has 75 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 Asthma 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: NCT01688986 reports 1 study location spanning 1 distinct geographic area — top geographies include North Carolina. 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. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
