Before she had even heard the term “public health,” Yushi Zhang, M.P.H. ’23, was leading a national breastfeeding movement across China.
Trained as a journalist, Zhang became interested in breastfeeding when she had her first child in 2010. Driven by the simple belief that, as mammals, the majority of women should be able to breastfeed, she was excited to learn more.
However, resources in China were scarce. China’s exclusive breastfeeding rate was 21% in 2013, significantly under the already low global average of 44%. Using baby formula is deeply ingrained in the modern Chinese culture; doctors at the time barely had the chance to touch upon the topic of breastfeeding in their medical training, and some were paid to promote formula use. There were only six lactation consultants in the country around the time Zhang delivered, five of whom were foreigners. All had received their training abroad.
An investigator by nature, Zhang was undeterred, and she turned to non-Chinese resources to learn more. “My advantage at the time was really because I was able to read English,” she said.
As she sifted through information online, she discovered that many others shared her curiosity about breastfeeding. Within a year, that mutual interest coalesced into a network of 40,000 women across China. The group’s goals went beyond education to peer support. Experts were brought in from abroad to train network members as on-call volunteers (and later paid professionals) capable of supporting postpartum practices in their local communities.
Zhang’s work didn’t stop at the individual level—she wanted to get to the root of the problem in the system and the culture. Most women in China gave birth in hospitals, many of which favored baby formula over breastfeeding, she said. Lacking traditional scientific credentials, Zhang found it challenging to gain traction with such large institutions. Yet, she found power in numbers. In addition to the 40,000-person volunteer network, she had amassed countless additional followers who supported her work.
“With that, you could consider us a market—and with that market, you all of a sudden had the power to talk with hospitals,” she said. “Because now, the women were united and could demand breastfeeding support, facilities and services.”
Her team provided consulting services to help private hospitals reshape their birth protocols that heavily affect breastfeeding initiation. Her work broadened the focus of these maternity wards from the technical and medical side of labor and birth to a wider range of public health maternal and infant essentials. Soon after, public hospitals got involved, too.
