Antenatal care is an important key for a healthy maternity. Maternal health literacy and particular cognitive and social skills required for healthy maternity include abilities to detect risk factors and taking actions for healthier life style and better nutrition during pregnancy. The association between maternal health literacy and outcome of pregnancy has been investigated in this study. Methods: This descriptive study was carried out in Isfahan Beheshti hospital in 2005. 150 parturient were selected randomly in postpartum ward based on inclusion criteria. Women with medical sciences education, chronic disease and pregnancy complications were excluded. Data were collected through questionnaires and analyzed with SPSS. Results: Based on the scores they were given from the questionnaire, 34% were classified as having low, 48% moderate and 18% good maternal health literacy. Women with adequate health literacy had significant difference in starting earlier and frequency of antenatal care, neonatal birth weight, mother hematocrit (HCT), ferrous and folic acid tablet consumption, pregnancy weight gain, gestational age at birth, method of delivery and breastfeeding. Other birth outcomes were similar between groups. Conclusion: Our findings suggest that good health literacy among pregnant women is associated with good pregnancy outcome and the fact that poor health literacy causes poor chance to gain a positive pregnancy outcome. A collaborative effort to increase maternal health literacy by assessing maternal health literacy levels in prenatal care unit, revision of educational materials into simple language, and provision of pregnant women with oral and video instruction in addition to written educational materials are highly recommended. Key words: Maternal health literacy, prenatal care, pregnancy outcomeshttp://ijnmr.mui.ac.ir/index.php/ijnmr/article/view/31http://ijnmr.mui.ac.ir/index.php/ijnmr/article/download/31/31
