Full summary

717 CHARS

The main outcome was weaning age, categorized into five levels. The results indicated that the most common breastfeeding duration was 6 to 12 months (38.6%), followed by 12 to 18 months (31.8%), which is shorter than the WHO recommendation. Factors associated with longer duration included maternal age under 30, good maternal health, correct breastfeeding knowledge, supportive attitudes, higher education, higher family income, vaginal delivery, early initiation of breastfeeding, and workplace support such as flexible hours and lactation rooms. Limitations include potential recall bias and selection bias due to the online survey method, though the authors note high internet penetration in the target age group.

ABSTRACT

Abstract Objective: To investigate the factors affecting the duration of continuous breastfeeding of infants within 2 years of age, and to explore intervention strategies that may promote breastfeeding duration in China. Method: A self-made electronic questionnaire was used to investigate the breastfeeding duration of infants, and the influencing factors were collected from three levels of individual, family, and social support. The Kruskal–Wallis rank sum test and the multivariable ordinal logistic regression model were used for data analysis. Subgroup analysis was carried out according to region and parity. Results: A total of 1001 valid samples from 26 provinces across the country were obtained. Among them, 9.9% breastfed for less than 6 months, 38.6% for 6 to 12 months, 31.8% for 12 to 18 months, 6.7% for 18 to 24 months, and 13.1% for more than 24 months. Barriers to sustained breastfeeding included the mother’s age at birth being over 31, education level below junior high, cesarean delivery, and the baby’s first nipple sucking at 2 to 24 h after birth. Factors that promote continued breastfeeding included freelancer or full-time mother, high breastfeeding knowledge score, supporting breastfeeding, baby with low birth weight, first bottle feeding at 4 months and later, first supplementary food at over 6 months old, high family income, the mother’s family and friends supporting breastfeeding, breastfeeding support conditions after returning to work, etc. Conclusion: The breastfeeding duration in China is generally short, and the proportion of mothers breastfeeding until the age of 2 years and above, recommended by WHO, is very low. Multiple factors at the individual, family, and social support levels influence the duration of breastfeeding. It is suggested to improve the current situation by strengthening health education, improving system security, and enhancing social support. Keywords: continuous breastfeeding, breastfeeding duration, China, risk factors
