Which of the following is a system factor affecting health literacy?

• A. The clarity of written materials
• B. A patient's reading skills
• C. Education level
• D. Age

Answer: (A)

Understanding health literacy involves how people obtain, process, and understand health information to make appropriate decisions. A system factor refers to how the health care system designs and delivers that information. The clarity of written materials fits this because it reflects how information is presented and communicated to patients. When materials are written in plain language, use simple sentences, clear layout, appropriate fonts, and supportive visuals, more patients can understand and follow instructions, regardless of their personal abilities.

The other options describe individual characteristics rather than system features. A patient’s reading skills, education level, and age influence how well they comprehend information, but they are about the person, not how information is produced or delivered by the system.
