Patients and controls reported similar sun exposure time during weekdays (94±82minutes/
day vs. 81±65minutes/day; p = 0.83), while during weekends patients spent significantly
less time outside compared to controls (103±85minutes/day vs. 124±87minutes/day; p =
0.02). Time elapsed from diagnosis positively correlated with time spent outside both during
weekdays (r = 0.194, p = 0.02) and weekends (r = 0.217, p = 0.01), and there was a step-up
in sun exposure starting three years after diagnosis. There was no significant difference
regarding composite sun protection score between patients and controls. Age was positively
correlated with number of sunburns per year and sun exposure for the purpose of tanning,
and was negatively correlated with the use of sun protection measures.
