Adolescents constitute an important audience for photoprotection programs. Sun exposure and sun protection habits acquired during adolescence have a significant impact on skin cancer incidence. We administered a questionnaire to 724 students about ultraviolet radiation effects, opinions about tanning, total time of sun exposure per day, photoprotection and activities in the sun. About 90% were aware of the association between sun exposure and skin cancer, and mass media was the main source of information. However, the great majority believed that tanning improved their appearance, and that it was worth taking the risk. The most prevalent outdoor activity among boys was sports; girls preferred walks and sunbathing. Sun exposure was significantly longer in summer, when 90% of the students went to the beach. About 47% reported sunscreen use in summer and only 3% reported using sunscreen during winter. These results emphasize the need for the promotion of photoprotective habits in our population and the importance of engaging physicians and school teachers in developing campaigns directed at this issue to achieve effective, long-lasting results. Adolescents are aware of the effects of ultraviolet radiation on the skin but campaigns have not successfully changed their sun exposure habits.
青少年是光保护项目的重要受众群体。青少年时期的日晒情况及防晒习惯对皮肤癌发病率有重大影响。我们对724名学生进行了问卷调查，内容涉及紫外线辐射的影响、对晒黑的看法、每日日晒总时长、光保护措施以及阳光下的活动。约90%的学生知晓日晒与皮肤癌之间的关联，大众媒体是主要信息来源。然而，绝大多数学生认为晒黑能改善外貌，且值得冒险一试。男孩中最普遍的户外活动是体育运动；女孩则更喜欢散步和日光浴。夏季的日晒时间明显更长，此时90%的学生前往海滩。约47%的学生报告在夏季使用防晒霜，而仅有3%的学生报告在冬季使用防晒霜。这些结果强调了在我们的人群中推广光保护习惯的必要性，以及让医生和学校教师参与开展针对此问题的宣传活动以取得有效、持久效果的重要性。青少年知晓紫外线辐射对皮肤的影响，但宣传活动尚未成功改变他们的日晒习惯。
