Prevalence of undiagnosed diabetes and prediabetes among voluntary blood donors in a tertiary health care setting

Background Finnish diabetes risk score (FINDRISC) questionnaire is a screening tool to estimate risk of type 2 diabetes. This study was conducted to find the prevalence rate of diabetes and prediabetes among voluntary blood donors using FINDRISC score as screening tool in large population.

Methods A total of 210 eligible blood donors were included in this study. After obtaining the consent, subjects will be assessed with FINDRISC questionnaire. The patients with score ≥12 points, blood samples were taken and HbA1c test will be done by particle enhance immunoturbidimetric test to detect diabetes and prediabetes.

Results Out of 210 donors, 93 had a score of ≥12 points among which the prevalence rate of prediabetes 43 (46.24%) and diabetes 14 (15.05%) was noted. Subjects with BMI in overweight category had diagnosed diabetes 4 (5.8%), prediabetes 20 (28.99%) and subjects in obese category had diagnosed diabetes 10 (31.25%) and prediabetes 19 (59.38%). It shows that BMI was significant indicator of undiagnosed diabetes.

Conclusions In this study we found that the prevalence rate of diabetes 14 (15.05%) and prediabetes 43 (46.24%) among voluntary blood donors. The FINDRISC questionnaire used was a reliable and valuable screening tool for detecting undiagnosed type 2 diabetes and prediabetes in large population. Person diagnosed early has a chance to delay disease progression and limit secondary damage caused by undiagnosed diabetes.
