Russell and Carol - hayle and hearty

I thought the article was very interesting

The incidence in the UK has risen from about 1.2 per 100,000 of population in 1971 to 3.1 in 2007. In Australia and New Zealand the incidence was nearly 38 per 100,000 in men and over 29 per 100,000 in women.

Between 1971 and 2007
- the package holiday boom happened (surely taking northern celtic skin types to areas where the native population has olive mediterranean or tropical skin types is bound to have some consequences?
- holidays in and travel to/from Austral/New Zealand must have increased at least 3 fold
- the sun cream revolution was born
- the ozone layer was damaged
- our diet has changed drastically with ingestion of Omega 3/6 in milk and dairy dropping

Have the incidence studies taken these into account - and if so how?

I was also interested in the risks of D3 levels being too low and the relative risk against UVB exposure being too high.

Thanks @Ephiny0 for the link to the BMJ discussion - fascinating.even if it is from 2008
