This study analysed spatial and temporal variation in childhood incidence of type 1 diabetes mellitus (T1DM) among Western Australia׳s 36 Health Districts from 1991 to 2010. There was a strong latitudinal gradient of 3.5% (95% CI, 0.2-7.2) increased risk of T1DM per degree south of the Equator, as averaged across the range 15-35° south. This pattern is consistent with the hypothesis of vitamin D deficiency at higher latitudes.
In addition there was a 2.4% (95% CI, 1.3-3.6) average increase in T1DM incidence per year.
These effects could not be explained by population density, socioeconomic status, remoteness or ethnicity.
Increase about 27 % (compounding 2.4% for a decade

- Incidence of 30 health problems related to vitamin D has doubled in a decade
- Prevent half of T1 Diabetes with vitamin D levels of 50 ng – Dec 2012
- Type 1 diabetes is increasing, vitamin D deficiency may be one of the reasons – Aug 2013
- T1 Diabetes increased about 15 percent per decade in Eastern Canada – Oct 2012 15% in Eastern Canada vs 27% in Australia

- Overview Diabetes and vitamin D contains the following summary
- Diabetes is 5X more frequent far from the equator
- Children getting 2,000 IU of vitamin D are 8X less likely to get Type 1 diabetes
- Obese people get less sun / Vitamin D - and also vitamin D gets lost in fat
- Sedentary people get less sun / Vitamin D
- Worldwide Diabetes increase has been concurrent with vitamin D decrease and air conditioning
- Elderly get 4X less vitamin D from the same amount of sun
Elderly also spend less time outdoors and have more clothes on
- All items in category Diabetes and Vitamin D
430 items: both Type 1 and Type 2
Vitamin D appears to both prevent and treat diabetes
- Appears that >2,000 IU will Prevent
- Appears that >4,000 IU will Treat , but not cure
- Appears that Calcium and Magnesium are needed for both Prevention and Treatment
which are just some of the vitamin D cofactors
