Purpose
Type-2 diabetes Mellitus (T2DM) is one of the leading causes of death and disability worldwide. This study examines temporal patterns of the global, regional, and national burden of T2DM in the last three decades.

Data and methods
The estimates of age, sex and location-wise incident cases, deaths, prevalent cases, and disability-adjusted-life-years (DALYs) and risk factors for 21 regions and 204 countries are retrieved from the Global Burden of Disease 2019 study from 1990 to 2019. Socio-demographic index (SDI) is used as the indicator of the development status of countries, and quadratic regression is employed to examine the relationship between country-level age-standardized rates and SDI.

Results
Globally, incident cases of T2DM more than doubled from 8.4 million [95% uncertainty interval, 7.8–9.1 million] in 1990 to 21.7 million [20.0–23.5 million] in 2019, and deaths more than doubled from 606,407 [573,069–637,508] to 1.5 million[1.4–1.6 million] between 1990 and 2019.
Global T2DM prevalence increased from

• 148.4 million [135.5–162.6 million] in 1990 to
• 437.9 million[402.0–477.0 million] in 2019.

In 2019, global age-standardized prevalence rate stood at 5282.8/100,000 [4853.6–5752.1], varying from 2174.5/100,000 [1924.3–2470.5] in Mongolia to 19876.8/100,000 [18211.1–21795.3] in American Samoa. SDI exhibited inverted-U shaped relationship with country-level age-standardised rates.
Globally,

• high body-mass-index (51.9%),
• ambient particulate matter pollution (13.6%),
• smoking (9.9%) and
• secondhand smoke (8.7%)

were the major contributing risk factors towards T2DM DALYs in 2019.

Conclusion
With ubiquitously rising prevalent cases globally, particularly in low and middle-income countries and regions, T2DM requires immediate attention and targeted policy response worldwide centered on lifestyle interventions (e.g., physical activity, smoking, diet, and obesity), air pollution control and cost-effective timely treatment.

VitaminDwiki - Overview Diabetes and vitamin D contains

• 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 554 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
• 90% less T2 Diabetes in the group having lots of Vitamin D
• Appears that Magnesium helps both Prevention and Treatment
• Many diabetics would be better treated if Gut-Friendly Vitamin D were used

Diabetic Epidemic

• Step back to 1994. Suppose an epidemic struck the United States, causing blindness, kidney failure, and leg amputations in steadily increasing numbers.
  Suppose that in less than a decade's time, the epidemic had victimized one out of every eight people
  That epidemic is real, and its name is diabetes, now the nation's sixth leading cause of death.
