Type 2 Diabetes: Screening for Children


Diabetes Canada recommends type 2 diabetes screening every 2 years for some children. Children who have not reached puberty and have 3 or more of the risk factors below should be screened. Children who have reached puberty and have 2 or more of the following risk factors:footnote 1

  • A body mass index (BMI) in the 95th percentile for his or her age and gender
  • A family history of type 2 diabetes
  • The child's mother had diabetes while pregnant with the child.
  • Hispanic, African, First Nations, Asian, or Pacific Island ancestry
  • Signs of not being able to use insulin properly (insulin resistance) or conditions linked with it:
  • Use of antipsychotic medicine or atypical neuroleptics

If the results of a blood glucose test mean that your child's blood sugar is higher than normal but not yet at the level of diabetes, he or she has (prediabetes). If your child eats a balanced diet and gets regular exercise, he or she may not develop diabetes.
