Aim
Conclusions
To evaluate FINDRISC as a screening tool in a Swedish
population, and in particular to identify individuals with IGT.
FINDRISC is an efficient tool to identify individuals with
abnormal glucose tolerance (AGT). In our Swedish
population more than half of the individuals with a risk score
≥ 15 had AGT and of those the majority had IFG. Preventive
strategies for IFG need to be developed.
Background
To detect individuals at risk to develop diabetes is of great
importance as there are efficient life-style interventions available
to prevent conversion to T2D in individuals with IGT. The
efficiency of life-style intervention in individuals with IFG is
uncertain. To distinguish between IFG and IGT is therefore of
great importance. FINDRISC is a screening instrument
developed in Finland, as a simple way to detect individuals at
high risk based of well known risk factors (age, BMI, waist
circumference, physical activity, heredity, known hypertension,
former high blood sugar, and fruit intake). The score reaches
from 0 to 26 points, and ≥15 is considered high.
The questionnaire was sent to a target
population of 6773 individuals

Method
The questionnaire was sent to a geographically defined
population of 6673 individuals 35-75 years old. They were all
encouraged to return the completed questionnaire to the
health care centre (HCC). Those with a score ≥15 were
asked to come to the HCC to have their blood glucose
examined, and to have an OGTT with a standard 75 g
glucose load made. Current WHO criteria were used to
define diabetes, IFG, and IGT, respectively.

Screening outcome is summerized in the flow chart, and
tables 1-2. Participation rate was 56%, and of 334 subjects
(9%) with a score ≥15, 30 had IGT (16%). In all 102
individuals (56%) had diabetes, IGT or IFG (AGT).
