Objective: 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.
Methods: 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.
Results: 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.
Conclusion: 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.
