The incidence and body site of skin cancers in the population groups of South Africa.

Data regarding basal cell carcinoma (BCC), squamous cell carcinoma of the skin (SSCC) and cutaneous melanoma (CM) in multiracial populations are sparse. Here the incidence and body site of these tumours in the South African population in 2000–2004 were analysed.

Self-reported sun-related knowledge, attitudes and behaviours among schoolchildren attending South African primary schools.

Skin cancer and other adverse health effects result from excess solar ultraviolet radiation exposure. Sun protective practices are important interventions for skin cancer prevention, particularly when implemented early in life. Several international studies have assessed childrens sun‐related knowledge, attitudes and behaviours in school settings but never before in Southern Africa, where multiethnic populations exist.

Sunburn risk among children and outdoor workers in South Africa and Reunion Island coastal sites.

To estimate potential sunburn risk for schoolchildren and outdoor workers, ground‐based ambient solar ultraviolet radiation (UVR) measurements were converted into possible child (5% of ambient solar UVR) and outdoor worker (20% of ambient solar UVR) solar UVR exposures by skin type and season for three coastal sites: Durban, Cape Point (South Africa) and Saint Denis (Reunion Island, France). Cumulative daily ambient solar UVR levels were relatively high at all sites, especially during summer, with maximum values of about 67, 57 and 74 Standard Erythemal Dose (SED) (1 SED = 100 J m−2) at Durban, Cape Point and Saint Denis respectively. Sunburn risk was evident for both children and outdoor workers, especially those with skin types I and II (extremely to moderately sensitive) during summer, early autumn and/or late spring at all three sites. Although results need to be verified with real‐time, instantaneous and nonintegrated personal solar UVR measurements, this understanding of sunburn risk is useful for initiating the development skin cancer prevention and sun protection awareness campaigns in both countries.

Solar ultraviolet radiation exposure and human health in South Africa: finding a balance.

In considering the likelihood of South Africa (SA) attaining the 2015 Millennium Development Goals, many health issues require urgent attention. The adverse effect of insufficient or excessive exposure to solar ultraviolet radiation (UVR) may exacerbate an already stressed public health service. These concerns become important when considering climate variability and patterns of behaviour.

Solar ultraviolet radiation in South Africa: clinical consequences for the skin

Due to its latitude, topography and cloudless skies, South Africa receives high solar ultraviolet radiation (UVR). This country has a multi-ethnic population classified into black, colored, Asian and white groups, who have varying degrees of response to sun exposure. In this review, information relating to the effects of solar UVR on skin cancer development, oculocutaneous albinism, melasma, the immune system and vitamin D production are discussed in the context of the peoples of South Africa. Methods of personal photoprotection are included. Effective sun safety messages for the public need to be developed, particularly aimed at the most susceptible groups, while recognizing the issues associated with variations in skin color in the South African population.
