In short: A systematic review of 111 articles found that individuals with limited health literacy often face significant barriers to effective healthcare. The researchers identified consistent patterns showing that these individuals are more likely to rely on emergency services and less likely to receive preventative screenings or vaccines.

This research highlights how difficulty understanding health information can create systemic barriers to well-being. By analyzing 96 high-quality studies, the team found that low literacy correlates with a reduced ability to manage medications and interpret health messages. However, the review was limited by a lack of evidence regarding oral health literacy and inconsistent results concerning the specific impact of numeracy on health outcomes.

The study was conducted by synthesizing existing literature from multiple databases to evaluate the relationship between literacy levels and various health metrics. A notable limitation is that the search was restricted to English-language publications.

Why it matters: Understanding health information is a critical factor in accessing preventative care and managing long-term health outcomes.
