Qualitative Assessment of the Work-Sleep Relationship
NCT03389828 · View on ClinicalTrials.gov ↗
Study Summary
Background: Sleep that does not last long and is low-quality is tied to a range of serious health issues. These range from obesity to early death. Research has shown that black people who are professionals or managers are more likely to have this kind of sleep than their white counterparts. Black people are also at higher risk than whites for health problems caused by insufficient sleep. Researchers want to learn more about why these differences exist. Objective: To study reasons for racial differences in the work-sleep relationship. Eligibility: Adults at least 25 years old who: * Are non-Hispanic black or non-Hispanic white * Are employed and work 38 or more hours a week * Live around Raleigh-Durham-Chapel Hill, NC, or Washington, DC Design: Participants will be screened with questions. They will give sociodemographic data like job title, annual income level, and gender. They will give their contact information. Participants will have 1 study visit. They will be in a closed, private conference room. They will join a focus group. The focus groups will be organized by to race, gender, and occupational class. Participants will give informed consent before the focus group begins. During the focus group, participants will be asked about their perceptions of health in general, and their typical work day. They will be asked about sleep. Participants will also fill out a short questionnaire about their job and sleep habits. Focus groups will be audio recorded. The entire session will last 90 to 120 minutes.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03389828
The ClinicalTrials.gov registry entry for NCT03389828 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 263 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 1 condition, with Sleep Health 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: NCT03389828 reports 2 study locations spanning 2 distinct geographic areas — top geographies include Maryland, 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.
