What is the reported prevalence for HL identified by teenage years (9-10)?

• A. 1000
• B. 100
• C. 10
• D. 0

Answer: (A)

Prevalence measures how common a condition is in a group at a given time, often expressed as a rate per a fixed number of individuals (commonly per 1,000). If the data report HL identified by teenage years (9–10) as 1,000, that value is interpreted as 1,000 per 1,000—i.e., the rate used in this dataset reaches 100% of the sample by that age. So the figure 1,000 best matches the reported prevalence in this context. The other numbers would represent lower rates and wouldn’t align with the reported finding.
