描述（由申请人提供）：黑色素瘤的发病率在世界范围内继续增加，尽管广泛的努力，在初级预防的基础上避免阳光照射的教育。儿童时期的阳光照射不仅增加了黑色素瘤的风险，而且还建立了阳光照射和保护的终身模式。在许多地区，具体的初级预防工作，包括儿童教育已经通过，对整体黑色素瘤负担的影响不大已经实现。这很可能是因为，正如大量先前的研究所表明的那样，在“安全”阳光照射的知识与任何由此产生的行为变化之间存在脱节。 我们在这项研究中的目标是测试一种新的基于课堂的动手教育干预，以激励青少年限制他们的阳光照射，并影响阳光照射行为的改变。我们已经在洛杉矶地区的学校开展了5年的SunSmart教育项目，旨在利用这些建立的关系来确保这项研究的成功。我们将从至少18所学校招募至少1，575名学生参加一项 我们的干预效果的随机试验，紫外线剂量测定实验室（与单独的SunSmart相比）在改变阳光照射行为。我们将建立基线阳光照射知识，态度和行为，进行干预，然后进行随访，以确定是否在至少315名学生的子集中改变了紫外线暴露行为。我们将使用剂量计测量日光暴露行为的真实的变化，以获得基线和后续紫外线暴露数据。 我们提出的方法是创新的，将学生的科学发现和个人的理解，他们自己的紫外线暴露在一个积极的教育干预，并验证行为变化使用剂量学。我们的试点数据表明，这种方法和干预本身都有很高的成功概率。这项研究的潜在影响是深远的，因为它是在该国暴露于最高水平紫外线的最大学龄儿童群体（近70万学龄儿童的潜在目标群体）中进行的。

DESCRIPTION (provided by applicant): Melanoma incidence rates continue to increase worldwide, despite widespread efforts at primary prevention based on sun exposure avoidance education. Childhood sun exposure not only increases melanoma risk, but also establishes lifetime patterns of sun exposure and protection. In many areas where specific primary prevention efforts involving childhood education have been adopted, little impact on the overall melanoma burden has been realized. This is most likely because, as a wealth of previous study has shown, there is a disconnect between knowledge of 'safe' sun exposures and any resulting behavioral change. Our objective in this study is to test a novel classroom-based hands-on educational intervention to motivate youth to limit their sun exposure, and affect sun exposure behavior change. We have been conducting a SunSmart educational program in Los Angeles area schools for 5 years, and aim to use those established relationships to ensure the success of this study. We will recruit at least 1,575 students from at least 18 schools to participate in a randomized trial of the effect our Intervention, the UV Dosimetry Laboratory (in comparison to SunSmart alone) in changing sun exposure behavior. We will establish baseline sun exposure knowledge, attitudes and behavior, conduct the Intervention, then conduct follow-up to determine if UV exposure behavior changed in a subset of at least 315 students. We will obtain baseline and follow-up UV exposure data using dosimeters measuring real change in sun exposure behavior. Our proposed approach is innovative, incorporating students' scientific discovery and personal understanding of their own UV exposures in an active educational intervention, and verifying behavior change using dosimetry. Our pilot data suggests a high probability of success of both the approach and the intervention itself. The potential impact of this study is far-reaching, because it is being conducted amongst the largest population of school children (a potential target population of almost 700,000 school children) exposed to the highest levels of UV in the country.
