Many middle-aged Americans lack basic health literacy
· News-MedicalA new Northwestern University study has found one in three middle-aged American adults ages 35 to 64 cannot consistently read prescription instructions correctly, understand medical forms or recall details from doctor visits involving chronic condition diagnoses. These skills - often referred to as health literacy - are critical for managing common conditions such as high blood pressure, high cholesterol and diabetes, which commonly emerge in midlife.
A sample size of 1,000 participants
A breakdown of the findings
They found:
- 32.5% had limited health literacy skills
- Lower health literacy was linked to lower income, less education and unemployment
- Those with poorer skills had more chronic conditions, were prescribed more medications and performed worse on cognitive testing
"Patients differ not just by demographics, but by their ability to manage their care," Vogeley said.
They also highlight broader implications for the health system.
"Billions are spent developing drugs, but far less is invested in helping patients use them correctly," Wolf said. "Improving understanding could significantly improve outcomes and reduce harm."
Chronic conditions in middle age
If patients fail to manage chronic conditions properly, it can result in hospital stays and worse health outcomes, Wolf said.
"The focus has always been on older adults, whom we might assume misdose medications because of cognitive decline, but our findings suggest health literacy is suboptimal even in middle age," Vogeley said. "Middle-aged adults become older adults, so if we look at this from an optimistic perspective, this can be a place for intervention."
