What percentage of the population is pre-diabetic or diabetic?

• A. 25%
• B. 45%
• C. 60%
• D. 75%

Answer: (B)

The point is to understand how many people are affected by higher-than-normal blood glucose across the population, by adding those with prediabetes to those with diabetes. Prediabetes is a state where blood sugar is elevated but not yet diabetic, and diabetes is when blood glucose meets diabetes criteria. Estimates commonly place about one in three adults in the prediabetes range and roughly one in ten with diabetes. Put together, that gives around 40–45% of adults whose glucose regulation is above normal. The figure most often cited in public health discussions is about 45%, making it the best match for this question. Options far from this—such as 25%—undervalue the prevalence since prediabetes alone is already around a third of adults. Values like 60% or 75% overstate the burden relative to current data, which show fewer than half of the population affected by either condition.
