Assess your risk of developing Type 2 diabetes based on key risk factors. Adapted for African populations with context-specific guidance on prevention.
Type 2 diabetes is rapidly becoming one of Africa's most serious health challenges. The International Diabetes Federation (IDF) estimates that 24 million adults in sub-Saharan Africa have diabetes, with the number projected to increase by 129% to reach 55 million by 2045 — the highest percentage increase of any world region. What makes this crisis particularly dangerous is that an estimated 54% of cases remain undiagnosed.
Several factors are driving this epidemic across the continent. Rapid urbanization is changing lifestyles and diets — traditional African foods rich in fibre, vegetables, and complex carbohydrates are being replaced by processed foods, sugary beverages, and refined grains. Physical activity levels are declining as more people move to cities and take up sedentary occupations. These lifestyle changes, combined with genetic predisposition, create a perfect storm for diabetes.
African populations face some unique risk factors. Research shows that people of African descent tend to develop diabetes at lower BMI thresholds compared to European populations. Central (abdominal) obesity is a particularly strong predictor of diabetes risk in African populations. Additionally, conditions like sickle cell trait, which is common in Africa, can affect HbA1c readings and complicate diagnosis.
The good news is that Type 2 diabetes is largely preventable. The landmark Diabetes Prevention Program (DPP) study showed that lifestyle interventions — modest weight loss of 5-7% of body weight combined with 150 minutes per week of moderate physical activity — reduced the risk of developing Type 2 diabetes by 58%. In African populations, returning to traditional diets rich in vegetables, legumes, whole grains, and lean proteins can significantly reduce risk.
Early screening is crucial. If you score moderate or higher on this risk assessment, you should get a fasting blood glucose test or HbA1c test from your healthcare provider. A fasting glucose of 7.0 mmol/L or higher, or an HbA1c of 6.5% or higher, indicates diabetes. Values in the "pre-diabetes" range (fasting glucose 5.6-6.9, HbA1c 5.7-6.4%) mean you can still prevent progression to full diabetes through lifestyle changes.
This calculator is based on the FINDRISC (Finnish Diabetes Risk Score), which has been validated in multiple populations and adapted for African contexts. It provides a risk estimate, not a diagnosis. A score of moderate or higher should prompt clinical screening with blood glucose or HbA1c testing.
Yes! Research shows that 58% of Type 2 diabetes cases can be prevented through lifestyle changes — moderate weight loss (5-7% of body weight), regular physical activity (150 min/week), and a healthy diet. Even small changes make a significant difference.
Ask your doctor for a fasting blood glucose test (normal: below 5.6 mmol/L) or an HbA1c test (normal: below 5.7%). These tests can detect both diabetes and pre-diabetes, giving you the opportunity to act early.
