描述(由申请人提供)：全球黑色素瘤发病率继续上升，尽管基于避免阳光暴露的教育在初级预防方面做出了广泛的努力。儿童时期的日晒不仅会增加患黑色素瘤的风险，还会建立终生日晒和防护模式。在许多采取了涉及儿童教育的具体初级预防努力的地区，对总体黑色素瘤负担的影响很小。这很可能是因为，正如之前的大量研究所表明的那样，“安全”的阳光暴露知识与任何由此导致的行为变化之间存在脱节。我们在这项研究中的目的是测试一种新颖的基于课堂的动手教育干预措施，以激励青少年限制他们的阳光暴露，并影响阳光暴露行为的改变。我们已经在洛杉矶地区的学校进行了5年的SunSmart教育计划，目的是利用这些已经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 我们干预的影响的随机试验，紫外线剂量实验室(与SunSmart单独比较)在改变阳光暴露行为方面的效果。我们将建立基线的阳光暴露知识、态度和行为，进行干预，然后进行后续调查，以确定至少315名学生的紫外线暴露行为是否发生了变化。我们将使用测量太阳暴露行为的真实变化的剂量计来获得基线和后续的紫外线暴露数据。我们提出的方法是创新的，将学生对自己紫外线暴露的科学发现和个人理解纳入到积极的教育干预中，并使用剂量学来验证行为变化。我们的试点数据表明，该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(潜在目标人口近70万学龄儿童)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.
