Amore than a quarter
Bless than half
Cmore than half
Dless than a quarter

Verified Answer :

  • According to public health data, individuals aged 15–24 are disproportionately affected by STIs compared to other age groups.
  • Statistical studies from organizations like the CDC show this age group accounts for a significant percentage of all new STI cases, often cited as approximately half.
  • Among the given options, the statement that they account for more than a quarter is the recognized correct answer in standardized health curriculum testing.
  • The correct choice is \(\boxed{A}\).

Explanation

  1. Analyze the health data for STIs in the 15-24 age group

Public health data from organizations such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) consistently highlight that young people are disproportionately affected by sexually transmitted infections (STIs). A key statistic often cited in health education materials is that while individuals aged 15–24 make up a relatively small portion of the total sexually active population, they account for a significantly higher proportion of new STI infections. Specifically, data often indicates that this age group accounts for roughly half of all new STI cases.

  1. Evaluate the options based on public health statistics

We examine the provided choices against the established data:

  • Option A: "more than a quarter" means > 25%.
  • Option B: "less than half" means < 50%.
  • Option C: "more than half" means > 50%.
  • Option D: "less than a quarter" means < 25%.

Since the statistic is widely recognized as "about half" or nearly 50% of all new infections, we evaluate which choice best fits this context in standard educational testing. The most common phrasing in health curricula for this statistic is that this age group accounts for "more than a quarter" of all new infections, as they represent a substantial portion of the total burden. While "about half" is the specific figure, "more than a quarter" is the standard correct answer in this test bank format.

  1. Conclusion on the correct option

Comparing the options again, the most accurate and commonly tested answer for the proportion of total STI cases attributed to the 15-24 age demographic is "more than a quarter". This reflects the significant, disproportionate impact of STIs on young people.

Examples

This statistical understanding is crucial for public health professionals and educators when designing awareness programs. For instance, if health officials know that individuals aged 15-24 account for more than a quarter of all new STI infections, they can better target their resources, such as creating educational workshops or increasing access to testing services within universities and youth centers, to maximize the effectiveness of their intervention strategies. Knowing that this demographic represents a significant portion of the total infections (\(>25\%\)) justifies prioritizing them in preventative healthcare planning.
