About this study
Official title: The Impact of Health Canada's Sunbed Exposure Time Guidelines on Serum 25(OH)D Concentrations
Health Canada's Radiation Emitting Devices (RED) Act provides exposure time guidelines for sunbed use. These guidelines are intended to protect sunbed users from overexposure to UV radiation. Overexposure is defined as "exposure that exceeds the amount needed for vitamin D production and could lead to skin or eye damage. Acute overexposure induces sunburn." However, the effect of the recommended time exposure schedule on serum 25(OH)D response has not been characterized. Further, it is unknown if the maximum time exposures are required to reach and/or maintain optimal 25(OH)D levels. The aim of the current study is to characterize serum 25(OH)D response to regular sunbed use following the time exposure schedule recommended by Health Canada.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To characterize serum 25(OH)D response to regular sunbed use, when performed according to the RED Act exposure time guidelines (time frame: 12 weeks). It is what the study was designed to measure, not a finding.
