Factors associated with exclusive breastfeeding practice among mothers in nine community health centres in Nanning city, China: a cross-sectional study.

BACKGROUND

The prevalence of exclusive breastfeeding (EBF) is suboptimal in China. There is limited evidence of effective interventions to increase EBF in China. Therefore, it is urgent to explore the potential factors that may be effective in promoting exclusive breastfeeding. Previous studies have mainly focused on socio-demographic factors and the Han ethnic group. This study explores more modifiable influencing factors of EBF in the Guangxi Zhuang Autonomous Region of China.

METHODS

The cross-sectional data used in this study were collected to provide baseline information on EBF prevalence for a breastfeeding promotion project. A total of 494 mothers of infants aged 0-5 months were recruited from nine community health centres in Nanning, China, in October 2019. Data were collected through face-to-face interviews using structured questionnaires. Infant feeding was measured by 24-h recall. The Chinese version of the Breastfeeding Self-Efficacy Scale-Short Form was used to examine the maternal breastfeeding self-efficacy. Univariate and multivariate logistic regressions were used to examine the factors associated with EBF practices.

RESULTS

In the present study, the prevalence of exclusive breastfeeding was 37.0%. Higher breastfeeding self-efficacy scores (adjusted odds ratio [AOR] 1.93; 95% confidence interval [CI] 1.25, 2.98), a college degree or above (AOR 2.15; 95% CI 1.24, 3.71), and early initiation of breastfeeding (AOR 2.06; 95% CI 1.29, 3.29) were positively associated with EBF practice. However, the preparation for infant formula before childbirth (AOR 0.30; 95% CI 0.17, 0.52) and premature birth (AOR 0.30; 95% CI 0.10, 0.87) were negatively associated with EBF practice.

CONCLUSIONS

Exclusive breastfeeding practice was suboptimal and associated with various factors in the study area. The prevalence of EBF was positively associated with higher breastfeeding self-efficacy, education level of mothers, and early initiation of breastfeeding, whereas premature birth and preparation for infant formula before childbirth were barriers to exclusive breastfeeding. Future intervention projects should target mothers with premature babies, lower levels of education, and breastfeeding self-efficacy. Breastfeeding-friendly practices, such as the early initiation of breastfeeding and regulations on breastmilk substitutes, should also be encouraged.
