How does low health literacy impact patients' likelihood of mortality over time according to the study?

Low health literacy has significant implications for patients' ability to understand health information and navigate the healthcare system effectively. Studies have shown that individuals with low health literacy are less likely to engage in preventive health behaviors, understand treatment instructions, and manage chronic conditions, all of which can contribute to poorer health outcomes over time.

The assertion that low health literacy increases the risk of mortality by 91% reflects the evidence that individuals who struggle to comprehend basic health information may face greater challenges in making informed health decisions, adhering to medication regimens, or accessing appropriate medical care. This can lead to a higher incidence of disease complications, insufficient disease management, and ultimately, a heightened risk of mortality.

In contrast, the other options imply either no effect or a lesser impact on mortality risk, which does not align with this body of evidence. Understanding the statistics behind low health literacy is crucial for healthcare providers, as it emphasizes the need for effective communication strategies to improve patient outcomes and potentially reduce mortality rates linked to health literacy deficits.
