Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact preprints@lancet.com.

Background: We evaluate the economic costs of limited health literacy in China using data from National Health Literacy Surveillance survey.
Methods: A sample of 6,454 adults aged 15-69 years old in Ningbo, China were selected from China’s National Health Literacy Surveillance in 2019. We use box plots to examine the distribution of out-of-pocket medical spending by level of health literacy. Estimates from two-part model (2PM) are used to assess the contribution of limited health literacy on expected individual medical costs.
Findings: Expected medical costs of inadequate health literacy is predicted to take 10% (176 yuan) of the expected medical expense of a typical individual living in Ningbo. This literacy-induced medical cost is greater among the rural, female and older groups. If the level of health literacy increases from 21% to 30% (target level by 2030), we predict the aggregate out-of-pocket medical expenditure in Ningbo will decrease by 0·9 billion yuan.
Interpretations: This paper highlights there are direct and indirect economic costs associated with limited health literacy. These results would help the policymakers to evaluate cost effectiveness of relevant programs that aim to improve residents’ health literacy.
