Designing Impactful Warnings for Sugary Drinks
NCT04382599 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this online RCT study is to examine how sugar-sweetened beverage (SSB) health warnings influence US adults' perceptions and reactions. The investigators have the following predictions: 1. SSB warnings will be perceived as more effective than the control (message topic) 2. Icon and graphic warnings will be perceived as more effective than text-only warnings (message type) The investigators will also examine the interaction of warning topic and warning type, but have no specific hypothesis about this interaction. Finally, the investigators will test the following predictions about the secondary outcomes: SSB warnings (vs. control), as well as icon and graphic warnings (vs text.warnings), will lead to lower perceived product healthfulness, lower purchase intentions, and higher cognitive elaboration.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04382599
The ClinicalTrials.gov registry entry for NCT04382599 describes a study currently listed as completed. It is categorized as NA, 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 1,078 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of North Carolina, Chapel Hill, which has 725 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 Health Behavior appearing as the primary indexed condition, and to 4 interventions — of which Text warning with square background is the first listed. 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: NCT04382599 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.
