What is a major limitation of strategies aimed at changing patient behavior to prevent disease?

• A. They are always 100% effective.
• B. They fail because not all patients will change; diseases still arise.
• C. They are immediate cures.
• D. They are unrelated to disease prevention.

Answer: (B)

The main idea is that strategies to change patient behavior can reduce risk, but they don’t eliminate it because adherence varies. Not everyone will adopt healthier habits, keep them long enough, or be able to overcome barriers such as access, income, or beliefs. When uptake is incomplete, diseases can still occur, which is why this limitation matters: prevention is often effective but not absolute, since behavior change doesn’t guarantee universal protection and other factors like genetics or environment also influence risk. The other statements misrepresent prevention: behavior change isn’t always 100% effective, isn’t an immediate cure, and is indeed related to preventing disease.
