To evaluate the feeding patterns of infants under 6 months of age in rural areas of Nanchong City, Sichuan Province, and to explore the driving factors of different feeding patterns.
A total of 837 pairs of infants under 6 months of age(<183 days of age) and their primary caregivers(450 male infants and 387 female infants, with an average age of(2.9±1.8) months, most of the primary caregivers were mothers(95.70%)) were selected by multi-stage random cluster sampling in Nanchong City in 2019.An electronic tablet equipped with a computer assisted system was used to input the face-to-face inquiry questionnaire to collect information, mainly including the sociodemographic characteristics of the subjects, infant feeding patterns, mothers' feeding knowledge, mothers' feeding attitudes, family support for breastfeeding, negative support from the surrounding population and other relevant information. Using disordered multi-classification Logistic regression, excluding non-maternal nursing samples, non-lactating mothers and mothers unable to breastfeed due to disease, 789 pairs of infants and their mothers were included in the regression model. After controlling the demographic characteristics of infants and their mothers, the independent influencing factors of exclusive breastfeeding relative to mixed feeding and artificial feeding were analyzed.
The rates of exclusive breastfeeding, mixed feeding and artificial feeding were 35.13%(294/837), 50.30%(421/837) and 14.57%(122/837) in rural areas of Nanchong. Compared with mixed feeding, mothers with high feeding knowledge(OR=2.06, 95%CI 1.47-2.86) were more likely to exclusively breastfeed. Compared with artificial feeding, mothers with high feeding knowledge(OR=2.48, 95%CI 1.36-4.54), positive attitude towards breastfeeding(OR=2.57, 95%CI 1.12-5.87) and high family support for breastfeeding(OR=3.01, 95%CI 1.73-5.24) were more likely to exclusively breastfeed, and mothers with negative support from the surrounding population(OR=0.37, 95%CI 0.14-0.98) were more likely to carry out artificial feeding.
In rural areas of Nanchong City, Sichuan Province, three ways of exclusive breastfeeding, mixed feeding and artificial feeding coexist. Mixed-feeding is the main method, and the rate of exclusive breastfeeding is low. Mothers' feeding knowledge is an important factor influencing feeding patterns, and breastfeeding attitudes and breastfeeding family support are the main drivers of artificial feeding.
评估四川省南充市农村地区6个月龄以下婴儿的喂养模式，并探讨不同喂养模式的驱动因素。
2019年在南充市采用多阶段随机整群抽样法，共选取837对6个月龄以下（＜183日龄）婴儿及其主要照料者（男婴450名，女婴387名，平均年龄为（2.9±1.8）个月，主要照料者大多为母亲（95.70%））。使用配备计算机辅助系统的电子平板电脑录入面对面询问问卷来收集信息，主要包括研究对象的社会人口学特征、婴儿喂养模式、母亲的喂养知识、母亲的喂养态度、家庭对母乳喂养的支持、周围人群的负面支持等相关信息。采用无序多分类Logistic回归，排除非母亲照料样本、非泌乳母亲及因病无法母乳喂养的母亲，789对婴儿及其母亲纳入回归模型。在控制婴儿及其母亲的人口学特征后，分析纯母乳喂养相对于混合喂养和人工喂养的独立影响因素。
南充农村地区纯母乳喂养、混合喂养和人工喂养率分别为35.13%（294/837）、50.30%（421/837）和14.57%（122/837）。与混合喂养相比，喂养知识水平高的母亲（OR=2.06，95%CI 1.47-2.86）更有可能进行纯母乳喂养。与人工喂养相比，喂养知识水平高的母亲（OR=2.48，95%CI 1.36-4.54）、对母乳喂养态度积极的母亲（OR=2.57，95%CI 1.12-5.87）以及家庭对母乳喂养支持度高的母亲（OR=3.01，95%CI 1.73-5.24）更有可能进行纯母乳喂养，而受到周围人群负面支持的母亲（OR=0.37，95%CI 0.14-0.98）更有可能进行人工喂养。
四川省南充市农村地区存在纯母乳喂养、混合喂养和人工喂养三种方式并存的情况。混合喂养是主要方式，纯母乳喂养率较低。母亲的喂养知识是影响喂养模式的重要因素之一，母乳喂养态度和母乳喂养家庭支持是人工喂养的主要驱动因素。
