Outdoor workers are at high risk of developing skin cancer. Primary prevention in this group can potentially reduce the incidence of skin cancer, and also potentiates the spontaneous remission of existing solar keratoses. A randomized controlled trial was conducted to evaluate a solar protection intervention targeting outdoor workers.
Outdoor workers were randomly allocated to an intervention (n = 65) or control group (n = 77). The intervention group received individual skin screening by a dermatologist and participated in an education session. Pre- and posttest outcome measures included solar protection behavior (assessed using a validated diary), knowledge, and attitudes.
There was a significant increase (16%) in the percentage of outdoor workers who were using a high level of solar protection at posttest compared to pretest in the intervention group, but there was no change in the control group. Although both groups improved in their knowledge score, the intervention group showed a significantly greater improvement at posttest. No changes in attitudes were detected.
The findings suggest that changes in solar protection are achievable with outdoor workers.
户外工作者患皮肤癌的风险很高。对这一群体进行一级预防有可能降低皮肤癌的发病率，也可能使现有的日光性角化病自然缓解。开展了一项随机对照试验，以评估针对户外工作者的防晒干预措施。
将户外工作者随机分为干预组（n = 65）或对照组（n = 77）。干预组接受皮肤科医生的个体皮肤筛查并参加一次教育课程。测试前和测试后的结果指标包括防晒行为（使用经过验证的日记进行评估）、知识和态度。
与测试前相比，干预组测试后使用高水平防晒措施的户外工作者百分比显著增加（16%），而对照组没有变化。尽管两组的知识得分均有所提高，但干预组在测试后的改善更为显著。未检测到态度方面的变化。
研究结果表明，户外工作者在防晒方面的改变是可以实现的。
