In 2024, the World Economic Forum and the McKinsey Health Institute published a report
about the disparities women face in accessing health care. Closing the women’s health
care gap, the findings show, could boost economies worldwide by as much as $1 trillion by 2040 – and collectively
give women millions more years of life.
At the University of South Carolina, faculty members in multiple fields are working
to address these disparities. From experts in public health and exercise science to
nursing and primary care, USC researchers are tackling the issues that underlie the
women’s health care gap while contributing to the health and well-being of all South
Carolinians.
Jihong Liu, professor of epidemiology in the Arnold School of Public Health, studies
the impact of maternal health care for women and their children. While one branch
of her research focuses on developmental origins of disease – how the mother’s health
in pregnancy affects her children’s – Liu also examines how a woman’s experiences
during pregnancy can affect her own health for a lifetime.
“Pregnancy is a critical time for mothers, especially as an opportunity for education,”
Liu says. “Before pregnancy, a person may have been smoking or drinking a lot, and
because of the pregnancy, she quits. If we can educate women to help them sustain
those healthy choices after pregnancy, that would be very beneficial.”
Liu says pregnancy is a time when women may find out about an issue or risk factor
for her health she would not have known about otherwise. For example, if a pregnant
person is diagnosed with gestational diabetes, she should take note because the risk
of developing Type 2 diabetes later in life is going to be higher. The same is true
for women who develop hypertension in pregnancy, which can reveal or even trigger
underlying health issues that increase their risk of cardiovascular disease.
“For many women, pregnancy may be one of the first times in life when they see a doctor
on a regular basis, and that is how they discover they have a chronic health condition,”
Liu says.
Pregnancy can be a window of opportunity for a woman to learn more about her own health
and how to take care of her body. It’s one of the reasons why prenatal health care
is so important – and why the postpartum period matters just as much as the pregnancy.
“Women deliver the baby and then put all their energy into caring for the newborn,
so they don’t pay as much attention to their own health. This is not good, so medical
associations have increasingly focused on postpartum care,” she says. “They now emphasize
the post-partum period as the ‘fourth trimester,’ a critical phase of maternal care.”
“We find that the program (Healthy Start) definitely helps women get more adequate
prenatal care. Participants are more likely to get enrolled in WIC and more likely
to reduce smoking. I think we see such positive effects because the program provides
targeted care based on women’s needs.”
One issue Liu has observed in post-partum care is that women go from regularly seeing
their OBGYN back into the care of a general practitioner – if they go back at all.
Valuable information, like a diagnosis of gestational diabetes, can slip through the
cracks. The patient may not know which information is important, and so she isn’t
able to advocate for herself as well.
“There is this disconnect between the OBGYN and the primary care provider, leaving
women to feel as though they are starting over with someone new. Without effective
care transitions, the clinician may have little knowledge of what occurred during
pregnancy, creating missed opportunities for prevention care.”
Liu says health care systems could close this care gap by employing community health
workers, who would help patients stay engaged in their care.
“This is a person who would help the patient understand the doctor’s notes after their
visit, who would check in on how things are going or who might be able to listen to
the patient’s concerns,” she says.
Liu has seen the community health work model in action through her extensive work
with Prisma Health’s Healthy Start (Midlands and Upstate). Healthy Start serves communities
across the U.S. where the infant mortality rates are 1.5 to 2 times higher than the
national average. Through community health workers, the program offers services and
support for financially disadvantaged and underserved women and their babies, who
are at increased risk for adverse health outcomes.
In 2018, Liu took on the role of evaluator for the program and has analyzed more than
20 years of data on the effectiveness of Healthy Start in South Carolina. Liu’s findings
laid the groundwork for Prisma Health to expand the program to six counties in the
Upstate in 2023. While the rate of infant mortality hasn’t changed as a result of
the Healthy Start program, Liu says other metrics have improved significantly, such
as birth weight.
“We find that the program definitely helps women get more adequate prenatal care.
Participants are more likely to get enrolled in WIC and more likely to reduce smoking.”
With 18 months of postpartum support, Liu says women enrolled in Healthy Start are
also encouraged to stick with the beneficial changes they made during pregnancy.
“I think we see such positive effects because the program provides targeted care based
on women’s needs,” she says.
In addition to her work with Healthy Start, Liu is also partnering with healthcare
providers at Prisma Health to monitor blood pressure in postpartum women who had hypertensive
disorder in pregnancy. The study is funded by the Duke Endowment.
“Remote monitoring allows us to track their symptoms daily. Then we’re using AI to
process the data and flag any study participants who need follow up with a provider,”
she says.
Liu also plans to study remote monitoring for participants at risk of high blood sugar
after gestational diabetes. If this new technology proves useful, she hopes to see
clinicians use it in the future to improve outcomes for postpartum women.
