Final answer:
Approximately 9% to 10% of the American population has some form of diagnosed diabetes, which includes both type 1 and type 2 diabetes. As such, option b) 10% is the best estimate for the percentage of the American population with diabetes.
Step-by-step explanation:
Approximately what percentage of the American population has some form of diabetes? The correct answer is b) 10%. However, the context provided suggests that American diabetes rates may be higher. There are two main types of diabetes: type 1 diabetes, which makes up about 5-10% of cases, and the more common type 2 diabetes, which accounts for about 90% of cases. Recent data indicates that nearly 30 million Americans have type 2 diabetes and an additional 90 million have pre-diabetes. Considering that the population of the United States is over 330 million, these figures suggest that approximately 9% to 10% of the population has diagnosed diabetes, with a much larger percentage likely having pre-diabetes, which could elevate the overall percentage impacted by diabetes.
Given the provided range of countries' data, the United States seems to have an above-average rate of 33.9 percent when considering all conditions and illnesses not limited to diabetes, suggesting a significant health concern.
