BACKGROUND: One of the effective factors on BF (Breastfeeding) continuation is Breastfeeding self-efficacy (BFSE). This study was conducted to determine the relationship between Health Literacy (HL) and BFSE in lactating mothers referring to primary health care centers. METHODS: This cross-sectional descriptive study was carried out on lactating mothers referring to primary health care centers in 2022. Multi-stage cluster sampling was done with 160 samples. The data were collected using demographic questionnaire, Persian shortened form of the BSES is a self-reported instrument for measuring a mother's Breastfeeding self-efficacy and Health Literacy for Iranian Adults (HELIA). Data were analyzed using ANOVA, independent t-test, correlation test and liner regression by SPSS version 16, with a significance level of 5%. RESULTS: There was a significant positive correlation between the HL score and its four domains( Reading, Behaviour and decision making, Accessing, and Understanding) except for the appraisal domain with BFSE score. The variables of use of formula, HL, duration of breastfeeding, and education were considered predictors of BFSE. CONCLUSION: In general, the results indicate a possible relationship between BFSE and mothers' HL. Therefore, improving mother's HL can have a positive effect on promoting infants’ nutrition.
