Interventions to Increase Sunscreen Use in Adults: A Review of the Literature

Skin cancers are the most common malignancy in Australia. Regular sunscreen use can reduce the incidence of cutaneous squamous cell carcinomas and actinic keratoses and has been associated with reducing the incidence of basal cell carcinomas and melanomas. However, sunscreen effectiveness is limited by the failure of the population to use it routinely. Interventions that promote the daily application of sunscreen may reduce the morbidity, mortality, and economic burden associated with skin malignancies. We reviewed the literature that examines the effectiveness of interventions to increase routine sunscreen use and found that no one strategy has been shown to be clearly effective in adults and that relatively few studies have aimed to increase routine use in groups at extreme skin cancer risk. Future research should consider how interventions can be best designed and how sunscreen use is measured so that cost-effective, feasible strategies that result in improved sunscreen use in adults can be established.
