*Adjusted for age, sex, education, occupational group, buttock melanin density, and left/right cast; see text for model details.
†By self-report.
‡Cumulative UVR dose is total UV exposure from age 6 y to current (units are 1,000 KJ/m2; range in these data, 0.51-5.87), that is, ambient UVR * self-reported time in sun.
