Solar keratoses: the association with erythemal ultraviolet radiation in Australia

The prevalence rate of solar keratoses among 2000 residents of Melbourne, Australia, was compared to the rate among 2113 residents of Maryborough, a north central Victorian city. There was a significantly higher prevalence rate among the Australian-born population of Maryborough compared with Melbou...

More Information
Summary:The prevalence rate of solar keratoses among 2000 residents of Melbourne, Australia, was compared to the rate among 2113 residents of Maryborough, a north central Victorian city. There was a significantly higher prevalence rate among the Australian-born population of Maryborough compared with Melbourne residents of the same age, sex, country of birth, and level of outdoor activity. Calculation of the erythemal ultraviolet radiation level revealed a 14.2% increase in the dose in Maryborough compared with that in Melbourne. These figures demonstrate a significant increase in the rate of solar keratoses, and thus the potential for the development of skin cancer, in all of the age groups studied. The difference was associated with a relatively small increase in ultraviolet radiation between two areas that are separated by a latitude distance of only 110 km.
