Exposure to solar ultraviolet radiation (UVR) is associated with several cutaneous adverse effects. However, to the best of our knowledge, in South Africa there are no formal guidelines on sun protection. A group of South African dermatologists and researchers convened over the course of 1 year to deliberate on integrated advice for sun protection among the multi-ethnic South African population. For people with light skin and those with genetic skin disorders (e.g., oculocutaneous albinism), sun protection was identified as critical to prevent sunburn, skin cancer, and photoaging. The evidence is less clear for people with medium and darker skin types, especially the latter, in whom melanin may confer a degree of protection against some parts of the solar spectrum. Recent studies have demonstrated that visible light can cause pigmentary changes in individuals with darker skin types in particular. Sun protection for people of all skin colors is beneficial to protect against photoaging and ocular damage. Herein sun protection advice is suggested for South Africans of all skin colors to reduce morbidity and mortality from sun exposure, particularly relating to skin cancer. Several knowledge gaps are identified as future research priorities.
暴露于太阳紫外线辐射(UVR)与多种皮肤不良反应有关。然而,据我们所知,南非尚无关于防晒的正式指南。一群南非皮肤科医生和研究人员在一年的时间里开会,商讨针对南非多种族人群的综合防晒建议。对于皮肤白皙的人和有遗传性皮肤疾病(例如眼皮肤白化病)的人来说,防晒被认为是预防晒伤、皮肤癌和光老化的关键。对于中等到深色皮肤类型的人,证据不太明确,尤其是后者,黑色素可能对太阳光谱的某些部分提供一定程度的保护。最近的研究表明,可见光会特别引起深色皮肤类型的个体出现色素变化。所有肤色的人都应采取防晒措施,以预防光老化和眼部损伤。本文提出了针对所有肤色南非人的防晒建议,以降低因日晒导致的发病率和死亡率,尤其是与皮肤癌相关的发病率和死亡率。文中还确定了几个知识空白领域作为未来的研究重点。
