Tanning bed use among UI Students

描述(由申请人提供)： 紫外线(UV)辐射是导致皮肤恶性黑色素瘤(CMM)和色素痣(普通葡萄胎)等前驱病变的主要病因危险因素。有人担心，日光灯或日光浴床的使用也可能与CMM有关，直接或间接地通过延长晒黑后的太阳暴露时间来实现。考虑到太阳灯和日光浴床的使用显然非常受欢迎，描述年轻人的日光浴床习惯似乎是势在必行的。许多研究表明，nevi是CMM的良好风险标志物。我们将在大学生中检测nevi，作为CMM的早期结果或替代品。 我们建议调查大学生对日光浴床、无晒黑产品和防晒霜的态度和使用情况。我们还将询问晒伤病史、最近的紫外线暴露和基于居住地的潜在紫外线暴露，以及太阳敏感度的潜在混杂影响(烧伤倾向、不能晒黑、肤色、头发颜色、眼睛颜色和雀斑)。这将通过在兄弟会和联谊会学生中进行的横断面研究来实现。这个方便的样本可能会比其他学生具有更高的社会经济地位和可支配收入。较高的社会经济地位与CMM风险增加有关。这些学生也可能增加了对日光浴床和无日晒日光产品的使用。 我们将在春假后进行这项基线调查。具体目标如下：1)描述兄弟会和联谊会学生对晒黑床、无阳光晒黑产品和防晒霜使用的态度和流行率；2)检查学生患雀斑的风险和上述因素；3)比较春假前使用晒黑床的学生和不使用晒黑床的学生春假后暴露和未暴露的肤色的平均差异。

DESCRIPTION (provided by applicant): Ultraviolet (UV) radiation is the major etiologic risk factor implicated in the development of cutaneous malignant melanoma (CMM) and in precursor lesions such as nevi (common moles). There is concern that sunlamp or tanning bed use may also be related to CMM, either directly or indirectly by prolonging sun exposure after tanning. Considering the apparent enormous popularity of sunlamp and tanning bed use, it seems imperative to describe tanning bed habits among young persons. Many studies have shown that nevi are good markers of risk for CMM. We will examine nevi, as an early outcome or surrogate for CMM, in college students. We propose to survey college students about their attitudes and use of tanning beds, sunless tanning products, and sunscreen. We will also ask about history of sunburns, recent UV exposure, and potential UV exposure based on places of residence along with the potential confounding effects of sun sensitivity (tendency to burn, inability to tan, skin color, hair color, eye color and freckling). This will be accomplished via a cross-sectional study conducted in fraternity and sorority students. This convenience sample will likely be at higher socioeconomic status and disposable income than other students. Higher socioeconomic status has been related to an increased CMM risk. Such students may also have increased use of tanning beds and sunless tanning products. We will conduct this baseline survey after Spring Break. The specific aims are as follows: 1) to describe the attitudes towards and prevalence of tanning bed, sunless tanning product, and sunscreen use in fraternity and sorority students, 2) to examine the risk of nevi with the previously mentioned factors in students, and 3) to compare mean differences in exposed and unexposed skin color after Spring Break between students who use tanning beds before Spring Break and those who do not.
