Final answer:
The lifetime prevalence of anxiety disorders in the United States is approximately 28 percent, which is typical for Western countries but on the higher end globally. With an average rate of 33.9 percent for a specific disease, the U.S. falls below the midpoint estimate of 43 percent when compared with the global range of 11.4 percent to 74.6 percent. So the correct answer is option (A).
Step-by-step explanation:
The lifetime prevalence of anxiety disorders in the United States is higher compared to most other nations. Specifically, the prevalence is about 28 percent over a lifetime, according to the Anxiety and Depression Association of America (2021). This rate is considered to be typical of Western nations but stands on the higher end when compared globally.
When we look at reports examining a range of mental health disorders in various countries, the prevalence rates can vary significantly, with some countries having rates as low as 11.4 percent and others as high as 74.6 percent. Using the given range, the estimated average percentage of people diagnosed with a particular disease in these countries would be the midpoint of the range, i.e., (11.4 + 74.6) / 2, which equals approximately 43 percent.
The United States, with an average rate of 33.9 percent, falls below this midpoint. This suggests that while the prevalence of anxiety disorders in the U.S. is high, it is not the highest when considering the full global context.
