Diabetes and prediabetes risk

CANRISK calculator (Canadian diabetes risk score)

CANRISK is a points score from Canada that adds ethnicity, education and a few other questions to the Finnish FINDRISC questions. You get a score, the study's estimated chance that you have prediabetes or type 2 diabetes now, and the points behind it.

Measure around your middle, just above the hip bones, after breathing out.

Are you physically active for at least 30 minutes most days (work or free time)?
Do you eat vegetables or fruit every day?
Has a doctor or nurse ever told you that you have high blood pressure, or have you taken medicine for it?
Has a blood test ever shown high blood sugar (for example at a check-up, during an illness or in pregnancy)?
Which close relatives have been diagnosed with diabetes? (tick all that apply)

What you will see

Your CANRISK score, the study's estimated chance of prediabetes or diabetes now, which of the paper's score lines it reaches, and the points behind it.

Validated in

6,223 Canadian adults screened between 2007 and 2011 in seven provinces (British Columbia, Saskatchewan, Manitoba, Ontario, New Brunswick, Nova Scotia and Prince Edward Island), most aged 40 to 74, with large urban sites chosen for a multi-ethnic sample. Everyone had an oral glucose tolerance test. The model was built in 70% of the group and checked in the other 30%.

Limits

CANRISK finds who may have prediabetes or undiagnosed type 2 diabetes now; it does not predict diabetes years ahead and it does not diagnose. It was checked on one blood test occasion. People already known to have diabetes were excluded, and sites differed on whether people with known prediabetes could take part. Latin American and other backgrounds carry no points because the study could not show a difference, not because there is none. Only a blood test (A1C, fasting glucose or a glucose tolerance test) can show whether you have diabetes.

CANRISK, FINDRISC or AUSDRISK?

CANRISK starts from the eight questions of the Finnish FINDRISC calculator (Lindström 2003) and adds sex, ethnicity, education and having had a large baby (Robinson 2011). In the Canadian study group it separated people with and without prediabetes or diabetes better than the FINDRISC score (area under the curve 0.75 against 0.66) (Robinson 2011). The US type 2 diabetes risk test was built in US survey data (Bang 2009), and the AUSDRISK calculator in Australian adults, to predict diabetes over 5 years (Chen 2010). Pick the one built closest to where you live.

Paper-based points from Table 3 of the paper (Robinson 2011). The authors made them by dividing each factor's weight in their model by 0.09393 and rounding; the highest possible total is 81 for women and 86 for men. The paper used the mother's background to stand in for both parents, because the father's background added nothing once the mother's was known (Robinson 2011). Our calculator accepts ages 40 to 74, where most of the study group sat. One inch is 2.54 cm.

Worked example from the paper: a 58-year-old White man whose mother has diabetes and who has no other risk factors scores 13 (age) + 6 (male) + 2 (one relative) = 21 (Robinson 2011).

What the score means

The paper gives a formula that turns the score into the chance of having prediabetes or diabetes at the time of testing in the study group: 1 / (1 + e-m), where m = -3.842 + 0.09393 x score. For the worked example (score 21) that is about 13% (Robinson 2011). In the study, the share with prediabetes or diabetes rose from 2% in the lowest tenth of scores to 57% in the highest tenth (Robinson 2011).

Table 5 of the paper (sensitivity, specificity and positive predictive value in the check group) (Robinson 2011). The authors note these lines are arbitrary and do not necessarily mark the right screening cut-offs; 32 is the line that best balanced missed cases against false alarms (Robinson 2011).

What to do with your result

A score of 21 or more is a reason to ask your doctor about an A1C or fasting glucose test, and a score of 33 or more a stronger one. In the US, the US Preventive Services Task Force recommends screening for prediabetes and type 2 diabetes in adults aged 35 to 70 who have overweight or obesity (USPSTF 2021), whatever any risk score says.
