The prevalence of use of sunscreens was assessed in an environment of high ultraviolet (UV) exposure by surveying 117 males and 126 females on two Queensland beaches. Using a questionnaire, information was obtained about their application of sunscreen on the day of participation in the study, thus eliminating recall error. It was found that 71% of the female and 68% of the male beach-goers sampled had applied sunscreen, 47% of which had the maximum Sun Protection Factor (15+) rating. There was no significant association found between usage and either skin colour or socio-economic status. Although 88% used a waterproof formulation, only 61% reapplied the sunscreen directly after swimming. Sunscreen was not applied to all exposed body parts, with over half of the subjects neglecting ears and lower limbs. Reported major reasons for use were to avoid skin cancer (44%), and to avoid sunburn (43%). The results of this study can assist in evaluating the effectiveness of present sun-protection campaigns in the short term.
