Keratinocyte skin cancer risks for working school teachers: scenarios and implications of the timing of scheduled duty periods in Queensland, Australia
Journal Publication ResearchOnline@JCUAbstract
Relative keratinocyte skin cancer risks attributable to lifetime occupational and casual sunlight exposures of working school teachers are assessed across the state of Queensland for 1578 schools. Relative risk modeling utilizing annual ultraviolet exposure assessments of teachers working in different geographic locations and exposed during periods of measured daily playground duty times for each school were made for local administrative education districts by considering traditional school opening and closing hours, and playground lunchtime schedules. State-wide, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) relative risk estimates varied by 24% for BCC and 45% for SCC. The highest relative risk was calculated for the state's north (sunshine) coast education district which showed that risk could increase by as much as 32% for BCC and 64% for SCC due to differences in teacher duty schedules. These results highlight the importance of playground duty scheduling as a significant risk factor contributing to the overall burden of preventable keratinocyte skin cancers in Queensland.
