Estimation of individual cumulative ultraviolet exposure using a geographically-adjusted, openly-accessible tool

摘要: Estimates of an individual’s cumulative ultraviolet (UV) radiation exposure can be useful since increases skin cancer risk, but a comprehensive tool that is practical for use in the clinic does not currently exist. The objective this study to develop geographically-adjusted systematically estimate self-reported UV exposure, investigate association these estimates with diagnosis, and assess test reliability. A 12-item online questionnaire from validated survey items was administered volunteers across United States results cross-referenced indices. Cumulative scores (CUES) were calculated correlated personal history case–control design. Reliability assessed separate convenience sample. 1,118 responses included overall sample; mean age respondents 46 (standard deviation 15, range 18 – 81) 150 (13 %) reported cancer. In bivariate analysis 1:2 age-matched cases (n = 149) controls (n = 298), associated (1) greater CUES prior first diagnosis than without (242,074 vs. 205,379, p = 0.003) (2) less engagement protective behaviors (p < 0.01). multivariate data, individuals lowest quartile likely compared those highest quartile. reliability testing among 19 volunteers, 2-week intra-class correlation coefficient 0.94. We have provided programming code as well itself via open access. useable better lifetime so higher levels may identified counseling on photo-protective measures.
