Mortality rates from melanoma are higher among Hispanic populations than non-Hispanic White (NHW) populations. Interventions to improve sun safety are needed. The Reveal Imager is a camera that uses standard cross-polarized flash photography to record surface and subsurface skin conditions.
This study aims to determine the intervention's effectiveness in increasing awareness of sun damage and exposure reduction between Hispanic and NHW populations.
A cohort of 322 participants, aged ≥18 years, were recruited from community events in 2018. Baseline information was collected on demographics, sun exposure, and perception of risk factors. A facial image was then captured using the Reveal Imager. The results were explained and counseling on sun safety was given, followed by filling out an immediate postimage survey. Chi-square tests, analysis of variance, Wilcoxon signed-rank test, McNemar tests, and multivariable logistic regression were used.
At follow-up, 125 of 141 (89%) Hispanic participants reported that viewing the UV photoaged image influenced intent-to-change sun protection behaviors, compared to 88 of 121 (73%) NHW participants (odds ratio 2.9, 95% CI 1.5-5.6). Of 141 Hispanic participants, 96 (68%) reported that they intended to increase sunscreen use, compared to only 41 of 121 (34%) NHW participants (P<.001).
We demonstrated an application of Reveal Imager for education and risk assessment. The Reveal Imager was especially helpful in motivating intention to change sun exposure among Hispanic populations.
西班牙裔人群中黑色素瘤的死亡率高于非西班牙裔白人（NHW）人群。需要采取干预措施来提高防晒意识。Reveal Imager是一款相机，它使用标准的交叉偏振闪光摄影来记录皮肤表面和皮下状况。
本研究旨在确定该干预措施在提高西班牙裔和非西班牙裔白人人群对阳光损伤的认识以及减少阳光暴露方面的有效性。
2018年从社区活动中招募了322名年龄≥18岁的参与者。收集了有关人口统计学、阳光暴露和风险因素认知的基线信息。然后使用Reveal Imager拍摄面部图像。解释结果并提供防晒咨询，随后填写图像拍摄后的即时调查问卷。使用了卡方检验、方差分析、威尔科克森符号秩检验、麦克尼马尔检验和多变量逻辑回归。
在随访中，141名西班牙裔参与者中有125名（89%）报告称，查看紫外线光老化图像影响了改变防晒行为的意图，相比之下，121名非西班牙裔白人参与者中有88名（73%）（优势比2.9，95%可信区间1.5 - 5.6）。在141名西班牙裔参与者中，96名（68%）报告称他们打算增加防晒霜的使用，相比之下，121名非西班牙裔白人参与者中只有41名（34%）（P<.001）。
我们展示了Reveal Imager在教育和风险评估方面的应用。Reveal Imager在激发西班牙裔人群改变阳光暴露意图方面特别有帮助。
