The prevalence and determinants of solar keratoses at a subtropical latitude (Queensland, Australia).

We report the association between skin pigmentation and individual sun exposure, and the occurrence of solar keratoses (SKs) in an unselected population, quantified for the first time. SKs were examined in a representative sample of 197 residents of the community of Nambour in Queensland, Australia. Estimates of sun exposure were combined with a measure of ultraviolet (UV) flux to estimate actual UV exposure, both occupational and recreational, during childhood and adult life.

Epidemiology of solar keratoses.

Solar keratoses (SKs) or actinic keratoses are common dysplastic epidermal lesions which occur in pale-skinned individuals who are chronically exposed to intense sunlight. Together with basal cell carcinomas and squamous cell carcinomas, they constitute a major public health problem in such individuals. Reported SK prevalence rates range from 11 to 25% in various northern hemisphere populations, and amongst Australian adults the range is from 40 to 60%.

A survey of sunscreen use and sun-protection practices in Darwin.

A study was conducted to determine the prevalence and determinants of sun-protection practices in a sample of the non-Aboriginal population at the outdoor weekend markets in subequatorial Darwin, Northern Territory, at a time of intense sun exposure, between 11 a.m. and 1 p.
