Objective: This systematic review and meta-analysis was conducted to assess the level of health literacy (HL) in the Iranian population.Data Sources: Persian and English-language articles were identified through Embase, MEDLINE, CINAHL, PsycINFO, SID, Web of Science, and hand-searching (search dates for articles on health literacy, 1990 to February 2016).Study Selection: Two reviewers independently selected studies that directly measured health literacy levels. Data Extraction: Abstracted article information were categorized into evidence tables by one reviewer; information accuracy was checked by a second reviewer. Two reviewers independently evaluated the study quality by using predefined inclusion criteria, and jointly the overall strength of evidence evaluated by the research team.Results: Twenty-eight relevant good-or fair-quality studies amongst 102 articles were identified, and 44 publications were assessed in full text. The researchers excluded 16 studies: Nine were reports with inadequate results and seven had low quality. Conclusions: Health Literacy of the Iranian population was inadequate and borderline. Therefore, the need to increase awareness and intervention to reduce poor HL in the Iranian population is crucial.Keywords: Health Literacy, Health Literacy Questionnaire, Iranian Population, Systematic Review
ContextAs a new concept, HL was introduced in 1974 for the first time in scientific publications related to health education. However, it did not receive significant attention for two decades. The term entered the health promotion domain in 1997 by Kick Busch (1). By definition, HL is one's capacity of achievement, interpretation and comprehension of primary healthcare information and services required for proper decision-making (2). It involves a collection of reading, listening, analysis, decision-making, and ability of applying these skills in health-related situations. It does not necessarily correlate with one's education level or general literacy (3-5). Health Literacy has been introduced by the World Health Organization (WHO), as a key determiner of healthcare. It has been recommended globally to create an association to constantly monitor and coordinate strategic activities, especially with the aim of promoting healthcare (6).Although it is not yet clear how HL affects healthrelated outcomes, there is plenty of evidence that many undesirable health consequences are due to inadequate HL (7). According to the investigations of the U.S. healthcare strategy center, those with low HL have fewer chances of comprehending health staff's oral or written advice. They, therefore, experience a lower health state and pay more for doctors' visits and are hospitalized more often (8, 9). They are less successful in performing self-care acts (10) as well as preventive acts (11) and, therefore, pay higher medical costs (12).The primary goal of developing HL is facilitating communicative healthcare and HIT strategies to promote health status and achieve equality in health service provision (13).Si...
