Risk and protective factors

Some behaviour and health factors can protect against developing diabetes (protective factors), while others can increase a person’s risk of developing the condition (risk factors) [29271].

Changes in lifestyle such as losing weight, increasing physical activity and eating healthy foods are all protective factors and reduce a person’s risk of getting diabetes, particularly type 2 diabetes [29271]. There is also evidence that breastfeeding can reduce the risk of maternal type 2 diabetes later in life [22946].

The risk factors for diabetes can be divided into two main categories: modifiable (can be changed) and non-modifiable (cannot be changed) [29271][440]. Non-modifiable factors include a person’s family history and age. Modifiable factors that increase the risk of developing diabetes, particularly type 2 diabetes, include:

  • high blood pressure
  • high blood cholesterol
  • tobacco smoking
  • low levels of physical activity
  • poor diet
  • being overweight or obese [29271][34292].

Another modifiable risk factor is pre-diabetes. Pre-diabetes is a condition when sugar (glucose) levels in the blood are high, but not high enough to be diabetes [33460]. Pre-diabetes has no symptoms. Aboriginal and Torres Strait Islander people are more likely than other people to have pre-diabetes. The prevention and management of pre-diabetes involve maintaining a healthy weight, eating a healthy diet, and being physically active. It is also important that people with pre-diabetes control their blood pressure, blood cholesterol and triglycerides.

Having more than one risk factor increases the risk of developing diabetes.
