Background: Excessive ultraviolet (UV) exposure can cause skin cancers, skin photoaging, and cataracts. Children are targeted by sun protection campaigns since high sun exposure and sunburn in childhood increase the risk of melanoma in adulthood. Little information is available about UV risk and exposure in children who take part in outdoor sports. Objective: To evaluate the risk of developing UV-induced skin lesions run by children who practice outdoor sports, and UV exposure and sun prevention measures during a soccer tournament. Methods: Firstly, we evaluated the relationship between melanocytic nevus - a skin lesion linked with UV exposure - and outdoor sports in 660 11-year old children. Secondly, we used the occasion of a one-day soccer tournament held in the spring to evaluate UV protective measures used by soccer players and the public. We also evaluated the UV index and cloud cover during the tournament, and calculated the UV dose and minimal erythema dose depending on skin phototype. Results The nevus count and acquired nevus count measured over the two years of the study was higher in the 344 children who practiced outdoor sports. Sun protective measures were insufficient for soccer players and the public despite high UV exposure. Conclusions This study shows that outdoor sports increase the risk of developing UV-induced skin lesions in childhood. During a one-day soccer tournament held in the spring, children and their parents were inadequately protected against the sun. These results suggest that sun prevention campaigns should be aimed at children who practice popular outdoor sports.
