Abstract

Summary

Queensland, Australia, has the highest rates of melanoma in the world and Queensland children have the greatest numbers of melanocytic naevi, the strongest risk factor for melanoma. Although both melanoma and naevi are broadly related to sun exposure in childhood, the relation to individual exposure early in life is difficult to study retrospectively in adults.

We surveyed 506 children aged 1-6 years who had been born in Townsville, North Queensland. Sun exposure was assessed by questionnaire and melanocytic naevi were counted using a standard international protocol. Very high counts (upper quarter) of melanocytic naevi were significantly associated with sun exposure of more than 4 hours per day (adjusted relative risk ratio 3·29; 95% Cl 1·12-9·69), and with a history of sunburn (1·89; 1·11-3·21). Melanocytic naevus counts increased with age, light skin reflectance, and freckling.

With exposure to intense ultraviolet light in Townsville, children develop melanocytic naevi early in life and in large numbers. We found that both acute and chronic exposure to sun are associated with their development.

      Future studies need to consider a greater emphasis on objective outcome measures. This could include measuring sunscreen weight (Diaz et al., 2012), assessing sunscreen applications using swabbing, changes in skin colour using spectrophotometry (O'Riordan et al., 2005), using smart technology to monitor hat or sun shirt use remotely, or counting changes in the number of freckles or moles (Harrison et al., 1994). Significant barriers to objective measurements are the greater costs of data collection and the potential for the inconvenience of participants compared to self-administered questionnaires.
