aUVR: UV radiation.

bFirst 7 days versus last 7 days of the 2-week wearing period.

cN/A: not applicable (parents not asked to report this on children).

dFirst 7 days versus last 7 days of the 2-week wearing period adjusted to include participants that had at least 4 days of UVR data.

eResponse options included never=1 to always=5.

f0=false, 1=true. Possible range of 0-5, or 0-10 for total knowledge.

g1=very unlikely, 5=very likely. Possible range of 1-10.

h1=not at all, 5=very much. Possible range of 1-20.

i1=strongly disagree, 5=strongly agree. Possible range of 1-20.

j1=no and I do not intend to start doing so in the next 6 months, 5=yes, I have been for more than 6 months. Possible range of 1-25.
