There is a requisite need to document the health literacy status and its determinants for making recommendations for public health promotions. The aim of this study was to determine the prevalence of limited health literacy and its associated factors in Iranian studies. Search queries were made in PubMed, SCOPUS, SID, Irandoc, IranMedex, and Magiran from ۲۰۰۰ to ۱ April ۲۰۱۶. The quality of the selected studies was assessed using the Critical Appraisal Skills Program checklists. Thirty one original papers were incorporated into the systematic review. We conducted meta-analysis using a random effects model. All analysis was performed using comprehensive meta-analysis [CMA] v.۲ statistical software. The thirty one papers reviewed include data on ۲۸,۱۳۸ subjects, and report a prevalence of low health literacy between ۴.۸% and ۷۹.۹%. Pooled analysis of these data show that the weighted prevalence of low health literacy was ۳۷.۰۱% (۹۵% confidence interval [CI]: ۳۶.۹۷%, ۳۷.۰۴%) and of marginal health, literacy was ۳۰.۷۶% (۹۵% CI: ۳۰.۷۲%, ۳۰.۷۹%). Low educational levels, old age, poor employment situation, and low economic status were the most important determinants of limited health literacy. In the multivariate meta-regression model, the years of the studies were significantly associated with health literacy prevalence rates. Only a third of the population had adequate health literacy and health literacy was poor among vulnerable groups such as the unemployed, older and less educated people. So, considering appropriate strategies for each of these groups could have a significant role in improving community health literacy.
