Effective solar protection is an uncommon practice among young people, increasing the likelihood of sunburn, sunstroke and skin cancers. This fact is more significant in the south of Brazil, where the prevalence of white skinned population is larger, being more prone to sun damage.
To study the practices of sun exposure and sun protection in high school students from the city of Carlos Barbosa - RS.
Cross-sectional study involving 775 students, enrolled on the first half of 2010, who had signed the consent form. We used a non-identifiable, self-administered questionnaire, with questions about related topics. Statistical analysis was performed using Chi-square or Fisher exact and t-Student tests. The study was approved by the Research Ethics Committee under the number 2010-115H.
Most students are exposed to the sun at the more critical periods, remaining exposed for more than an hour. Five hundred and seventy-six students (74,3%) reported using sunscreen, but less than 10% did it during all months of the year. Female teenagers are most likely to use sunscreen (p <0.001) and to spend less time exposed to sunlight (p <0.001).
Most high school students from Carlos Barbosa had unsuitable sun exposure and sun protection habits, characterizing a high risk behavior for skin diseases. The existence of public programs for clarification of the risks to the population and the subsidization of sun protection products were suggested by these young people.
有效的防晒措施在年轻人中并不常见，这增加了晒伤、中暑和皮肤癌的发生几率。在巴西南部，这一情况更为突出，当地白皮肤人群比例较高，更容易受到阳光伤害。
研究南里奥格兰德州卡洛斯·巴尔博萨市高中生的日晒及防晒行为。
2010年上半年开展的一项横断面研究，纳入775名签署了知情同意书的学生。采用一份不记名的自填式问卷，询问相关主题的问题。使用卡方检验、Fisher精确检验和t检验进行统计分析。本研究经研究伦理委员会批准，批准号为2010 - 115H。
大多数学生在日照最强烈的时段外出，且暴露时间超过一小时。576名学生（74.3%）报告使用过防晒霜，但全年都使用的不到10%。女性青少年更有可能使用防晒霜（p <0.001），且晒太阳的时间较少（p <0.001）。
卡洛斯·巴尔博萨市的大多数高中生日晒及防晒习惯不当，这是一种患皮肤病的高风险行为。这些年轻人建议开展公共项目，向民众普及风险知识，并补贴防晒产品。
