Which statement about health literacy is accurate?

• A. It has no impact on health outcomes.
• B. It only affects written communication.
• C. It affects adherence and outcomes.
• D. It only applies to elderly patients.

Answer: (C)

Health literacy is the ability to obtain, understand, and use health information to make appropriate decisions. When people can read labels, understand dosing, interpret instructions, and navigate the health system, they’re more likely to follow treatment plans, attend follow-up appointments, and recognize when to seek care. This engagement and adherence often lead to better disease control, fewer complications, and improved overall health outcomes. The other statements miss essential parts of the picture: health literacy does impact outcomes, it isn’t limited to written communication, and it isn’t confined to elderly patients.
