More than a quarter of American adults have what’s called poor health literacy. They're likely to have trouble interpreting important written health information—or have difficulties communicating well with doctors and nurses. But does that mean they're actually more likely to miss taking scheduled medications or get sick?

Yes, say researchers who pored over nearly 100 recent studies looking at this issue. People with poor health literacy tend to be hospitalized more often, get fewer recommended screenings and are more likely to misunderstand instructions. The review is in the Annals of Internal Medicine. [Nancy Berkman et al., "Low Health Literacy and Health Outcomes: An Updated Systematic Review"]

Throw in the fact that, on average, Americans 65 and older get more than 30 prescriptions each year. Odds are, many of those people will have trouble understanding when and how they are supposed to take at least some of those medications.

Other researchers have pointed out that to improve health literacy, we’ll need to better understand how it is people most often get mixed up. In the meantime, checklists of meds and double-checking pill bottle labels can help ward off mistakes—and keep you off the wards.

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
