Clinical Trial Summary

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.

Outcome

Type Measure Description Time frame Safety issue
Primary Prevalence of Sun Protection Practices What proportion of 8 sun protection practices did participants do on reported days of exercise. Participants responded to 8 potential sun protection practices and provided the number of days they did each practice within the timeframe provided (3 months at baseline; 4 weeks at posttest). Participants also provided number of days of outdoor exercises within timeframe. Proportion was calculated by dividing the frequency of each sun protection practice by the number of days of outdoor exercise within the timeframe. Mean score of all sun protection practices per day of outdoor exercise is reported. Range = 0-1, where a higher number indicates more sun safety practices performed. A proportion was used to account for different timeframes at baseline and posttest. baseline and four-weeks post intervention
Primary Prevalence of Sunburn Participants were asked if their skin was sunburned (described as being red and/or painful from exposure to the sun) in the past three months, and if so, how many times. Baseline
Primary Prevalence of Sunburn Participants were asked if their skin was sunburned (described as being red and/or painful from exposure to the sun) in the past four weeks, and if so, how many times. four-weeks post intervention
Secondary Physical Activity (Godin Leisure-Time Exercise Questionnaire) Duration in minutes of exercise multiplied by number of times per week, in the past 7 days. Total minutes per week calculated; mean per treatment group reported. Baseline
Secondary Physical Activity (Godin Leisure-Time Exercise Questionnaire) Duration in minutes of exercise multiplied by number of times per week, in the past 7 days. Total minutes per week calculated; mean per treatment group reported. four-weeks post intervention
Secondary Recall of Sun Protection Messages Participants in intervention only were asked about how many messages they read. Scale ranges from 0 - 3. 0 = none of the messages; 1 = some of the messages; 2 = most of the messages; 3 = all of the messages. Higher score indicates higher message recall. four weeks post intervention
Secondary Self-Efficacy for Sun Protection When Exercising Participants were asked: how confident are you that you can practice sun safety next time that you exercise. 1 = not confident; 2 = a little confident; 3 = somewhat confident; 4 = very confident. Higher scores indicates more self-efficacy for sun safety. baseline and four-weeks post intervention
Secondary Range of Physical Activity (Godin Leisure-Time Exercise Questionnaire) Duration in minutes of exercise multiplied by number of times per week, in the past 7 days. Total minutes per week calculated; mean per treatment group reported. baseline
Secondary Range of Physical Activity (Godin Leisure-Time Exercise Questionnaire) Duration in minutes of exercise multiplied by number of times per week, in the past 7 days. Total minutes per week calculated; mean per treatment group reported. four weeks post-intervention
