PURPOSE Sun-exposure can cause health problems, including melanoma and nonmelanoma skin cancer, especially in Australia where the incidence of skin cancer is particularly high. Childhood cancer survivors (CCSs) have an augmented risk due to previous cancer history and treatment. Despite recommendations advising sun protection, CCSs may be placing themselves at risk. We considered daily summer sun-exposure in an Australian cohort of CCSs and in community reference groups, and identified factors associated with sun-exposure in these populations. METHODS Summer sun-exposure data were collected on 471 CCSs (119 parents of survivors aged <16, and 352 survivors aged ≥16) and a reference group of 470 participants from the community (155 parents of children aged <16, and 355 adults aged ≥16). Survivors completed paper questionnaires and the reference groups completed an online survey. Medical records confirmed survivors' clinical information. Ordinal logistic regressions identified factors associated with daily summer sun-exposure. RESULTS More daily summer sun-exposure was reported by both parents reporting for the young survivors (U = 5,522.5, P < .001; U = 31,412, P < .001) and by older survivors (U = 5,039.5, P < .001; U = 29,913, P < .001). Among younger participants greater sun-exposure was associated with being a CCS, while in older participants, greater sun-exposure was associated with being a CCS, a male, smoker/ex-smoker and was also increased in those with more sensitive skin reaction to sunlight. Focusing only on the CCSs, when treatments were considered, none statistically predicted sun-exposure in young CCSs while older CCSs who received radiotherapy were less likely to spend excess time in the sun. CONCLUSION CCSs have sun-exposure at times of day when sun-related skin damage is highest, despite advice to avoid highest risk times. This data can inform sun-protection programs and lifestyle advice aimed at ameliorating the potential increased risk of skin cancer in CCSs.

澳大利亚儿童癌症幸存者和社区参考人群的夏季日晒。

目的防晒会导致健康问题，包括黑色素瘤和非黑色素瘤皮肤癌，特别是在澳大利亚，皮肤癌的发病率特别高。由于先前的癌症病史和治疗方法，儿童癌症幸存者（CCS）的风险增加。尽管有建议建议采取防晒措施，但CCS可能会将自己置于危险之中。我们在澳大利亚CCS群体和社区参考人群中考虑了夏季的日照，并确定了这些人群中与日照有关的因素。方法收集了471名CCS（119名<16岁的幸存者的父母和352名≥16岁的幸存者的父母）和社区的470名参与者（155名<16岁的孩子的父母和355名成年人的参考）的夏季暴露数据。 ≥16）。幸存者完成了纸质问卷，参考小组完成了在线调查。医疗记录证实了幸存者的临床信息。序数逻辑回归确定了与每天夏季日晒有关的因素。结果父母双方报告年轻生还者（U = 5,522.5，P <.001; U = 31,412，P <.001）和年长生还（U = 5,039.5，P <.001; U = 29,913，P <.001）。在年轻的参与者中，更多的阳光照射与CCS有关，而在年长的参与者中，更多的阳光照射与CCS，男性，吸烟者/前吸烟者有关，并且对皮肤的反应更敏感的人也会增加阳光。在考虑治疗时，仅关注CCS，在年轻的CCS中，没有统计学上的预测会暴露在阳光下，而接受放射疗法的年长的CCS在太阳下花费过多时间的可能性较小。结论CCS在一天中与太阳相关的皮肤损害最高的时候会暴露在阳光下，尽管建议避免最高风险时间。该数据可为旨在减轻CCS皮肤癌潜在风险增加的防晒程序和生活方式建议提供参考。
