Abstract: Objective To analyze the status and influencing factors of exclusive breastfeeding, and to provide theoretical basis for improving the rate of exclusive breastfeeding. Methods Pregnant women who gave birth to live babies in the Affiliated Hospital of a medical university and People's Hospital of Luzhou City from April to June in 2019 were selected. The questionnaire survey was conducted at 6 months after delivery, including basic information, feeding status within 6 months and related information. Descriptive epidemiological method was used to describe the status of exclusive breastfeeding and univariate and multivariate logistic regressions were used to analyze the influencing factors. Results A total of 448 mothers of 6-month-old newborns aged 19-46 in Luzhou City were investigated. The age of 26-35 years old, college education or above, urban citizen and primipara accounted for 56.7%, 94.8%, 95.8% and 58.3%, respectively. The rate of exclusive breastfeeding was 61.16%. Multivariate logistic regression analysis showed that mothers with older age（OR=0.548, 0.453）, sunken or flattened nipples （OR=0.386）, postpartum depression （OR=0.556）, and poor sleep quality （OR=0.557） were less likely to exclusive breastfeed. The mothers who breastfed within 1 hour after birth （OR=2.375）, family members, especially husband who supported breastfeeding （OR=7.050）, and participated in prenatal health education during pregnancy （OR=1.578） were more likely to exclusive breastfeed. Conclusion The status of exclusive breastfeeding in Luzhou City is good, and there are many influencing factors. We can formulate corresponding intervention measures according to the characteristics of local mothers, so as to improve the rate of exclusive breastfeeding.
