Official title

Using Retrospective and Real-Time Physical Activity Tracking to Predict Risk of Sunburn in Outdoor Exercisers on Strava

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Recreational UV exposure is associated with every form of skin cancer and individuals who engage in more physical activity have a higher prevalence of sunburn, a proximal biomarker of melanoma risk, perhaps explaining why melanoma is the only cancer with which physical activity is positively correlated. Mobile technology for tracking physical activity has become increasingly prevalent and Strava, an activity tracking app and social networking site for athletes, is one of the most popular of these technologies. This research will test the feasibility of delivering location-based, ecologically-valid sun safety advice to Strava users at times when they are predicted to be engaged in outdoor physical activity, by utilizing Strava's public open-source Applications Programming Interface.
