Limited Health Literacy in Portugal Assessed with the Newest Vital Sign.
In Portugal, health literacy has started to be addressed through national policies, but research on the topic is still scarce. We aimed to estimate the prevalence and sociodemographic correlates of limited health literacy in Portugal using an existing health literacy instrument, the Newest Vital Sign. ⋯ We validated a brief and simple instrument and estimated the prevalence of limited health literacy in the literate Portuguese population at roughly three out of four people.
