Solar UVR is a major cause of skin cancer but also an important source of vitamin D (VitD), essential for musculoskeletal health. Conflicting public health messages may confuse patients with skin cancer prone to further skin cancer.
To explore the knowledge, behaviour and attitudes of patients with skin cancer to sunlight exposure and VitD sources.
Patients (n = 10) previously treated for multiple basal cell cancer in a hospital setting participated in focus group sessions with semi-structured discussions to explore: knowledge of VitD, sun-avoidance behaviour and attitude towards sunlight exposure messages. Thematic data analysis was performed using software programme MAXQDA11.
Pre-existing knowledge of VitD was low. Most patients practised sun avoidance and were not inclined to increase exposure. Patients did not perceive VitD deficiency as a substantial risk to their own health, or a need to take VitD supplements. They aimed to increase VitD status through dietary intake, but knowledge of food VitD content was lacking.
The patients with skin cancer, appropriate to their heightened skin cancer risk, appeared unlikely to increase their sun exposure to gain VitD. However, education is required regarding the generally low levels of VitD in foodstuffs, and the requirement for supplements/fortified foods if strict sun avoidance is employed.
日光紫外线辐射是皮肤癌的主要病因，但也是维生素D（VitD）的重要来源，维生素D对肌肉骨骼健康至关重要。相互矛盾的公共卫生信息可能会使易患皮肤癌的患者感到困惑。
探讨皮肤癌患者对阳光照射和维生素D来源的知识、行为及态度。
在医院环境中，曾接受过多次基底细胞癌治疗的10名患者参加了焦点小组会议，进行半结构化讨论，以探讨：维生素D知识、防晒行为以及对阳光照射信息的态度。使用MAXQDA11软件程序进行主题数据分析。
患者对维生素D的已有知识水平较低。大多数患者采取防晒措施，且不倾向于增加阳光照射。患者未将维生素D缺乏视为对自身健康的重大风险，也不认为有必要补充维生素D。他们旨在通过饮食摄入来提高维生素D水平，但缺乏对食物中维生素D含量的了解。
鉴于皮肤癌患者皮肤癌风险较高，他们似乎不太可能为获取维生素D而增加阳光照射。然而，需要对他们进行教育，告知其食物中维生素D含量普遍较低，以及如果严格避免阳光照射则需要补充剂/强化食品。
