Diabetes prevalence over time

 

The increase in reported prevalence is influenced by numerous factors, including:

  • Demographic change - diabetes is more prevalent in older age groups, so increasing numbers of older people each year will increase the prevalence of diabetes.
  • Improved survival – related to improvements in treatment and care of all medical conditions.
  • Earlier diagnosis, including those in younger age groups.
  • Rising obesity levels - having a body mass index (BMI) in the overweight or obese range (BMI >25 and >30 respectively) is the most significant modifiable risk factor for developing T2DM.
