What are the determinants of low exclusive breastfeeding prevalence in China? A cross-sectional study

Exclusive breastfeeding (EBF) status is far from the national target in China. To identify the modifiable factors associated with EBF of infants aged under 6 months in China. A cross-sectional study was conducted in 12 provinces/municipalities across China in 2017-2018. We used multistage stratified cluster sampling and collected data through face-to-face interviews with mothers using an electronic questionnaire. Totally, 5287 pairs of mother-infant aged <6 months were investigated. The EBF prevalence was 29.2% (1544/5287). Mothers with correct knowledge of colostrum (adjusted odds ratio [AOR]:1.32, 95% confidence interval [CI]: 1.07, 1.62), EBF (AOR: 1.39, 95% CI: 1.06, 1.81) and the highest scores of perceptions for breastfeeding benefits (AOR: 1.36, 95% CI: 1.14, 1.61) were more likely to exclusively breastfeed. However, mothers with more frequent unwillingness of breastfeeding during the first month postpartum were less likely to practice EBF (AOR: 0.68, 95% CI: 0.52, 0.90). Infants having their first breast milk within 24 h of birth increased the odds of EBF (AOR: 2.41, 95% CI: 1.86, 3.13). Infants were less likely to be exclusively breastfed in the families in which the main caregiver was the grandmothers. Mothers without receiving infant formula feeding suggestions via the health facilities, media, or the Internet (AOR: 1.57, 95% CI: 1.33, 1.85) or without the experience of infant formula feeding in public (AOR: 1.45, 95% CI: 1.23, 1.72) might more likely to practice EBF. To acquire comprehensively correct knowledge and keep a positive attitude of breastfeeding for the mothers are crucial for improving the EBF prevalence. Family supports are potential interventions worth focusing on. Infant formula promotion remains a great barrier for EBF in China.

Automated summary

Exclusive breastfeeding (EBF) status is below the national target in China. Correct knowledge, positive attitude, and family support are important factors for promoting EBF. However, unwillingness to breastfeed after childbirth and grandmother as the main caregiver reduce the likelihood of EBF. The promotion of infant formula feeding remains a significant barrier to EBF in China.
