T1 Diabetes 35 percent more likely if 10 degrees further from equator (less vitamin D) – June 2014

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

Pages listed in BOTH of the categories Diabetes and Infant/Child

  • 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 414 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
