Exclusive breastfeeding rate and related factors among mothers within maternal health WeChat groups in Jiaxing, Zhejiang province, China: a cross-sectional survey.

Background: The health workers in Jiaxing of China have established maternal health WeChat groups for maternal health education and management since 2019. Pregnant women in Jiaxing are invited to join the WeChat groups and a health worker as the group manager provides health education and individual counselling for women within the group. This study aimed to investigate the exclusive breastfeeding (EBF) status up to six months and its associated factors among the mothers of infants aged 7-12 months within the WeChat groups. Methods: This was a cross-sectional survey on healthy mothers with infants aged 7-12 months from seven maternal health WeChat groups in October 2021 in Jiaxing, China. EBF was defined as breastfeeding infants exclusively up to six months. Data including breastfeeding practice from birth to six months, maternal sociodemographic and obstetric characteristics, hospitalization information, work related factors and reasons for non-EBF up to six months were collected using an online self-administered questionnaire. A multivariable logistic regression analysis was performed to identify the factors independently associated with EBF up to 6 months. Results: A total of 822 mothers were included in this study. Among them, 586 mothers (71.3%) exclusively breastfed infants up to six months. Multivariable logistic regression analysis showed that older maternal age (adjusted odds ratio [AOR] 0.956; 95% confidence interval [CI] 0.917, 0.997) and perceived insufficient breast milk (AOR 0.104; 95% CI 0.072, 0.149) were associated with lower odds of EBF up to six months. The five of common reasons for non-EBF up to six months were no or insufficient breast milk (59.8%), return to work (23.9%), no flexible nursing breaks at work (18.2 %), infant crying or feeling tired or troubled with breastfeeding (9.7%), and nipple and breast problems (9.3%). Conclusion: About 71.3% of infants were exclusively breastfed until six months of age in our WeChat groups. Perceived insufficient breast milk and work related factors are the main barriers to EBF up to six months in this setting. However, further comparative study is needed to confirm the effect of WeChat groups on breastfeeding. [ABSTRACT FROM AUTHOR]
