“[The topic] is rooted in health coaching, specifically for improving health, overall quality of life and well-being, but the skillset that we teach is very applicable across various professions business settings, and so forth,” said Binks, who has a PhD in clinical psychology and behavioral medicine.

With more than 20 years’ experience working with patients, he has typically done work under the umbrella of the organizations that he works for, Binks said his career has been about building new clinical and research programs where they didn't exist or improving those that were already in place.

He started with a health coaching program at the Duke Diet and Fitness Center, where he was a director of behavioral health, research, and new business and strategic alliances, and continued his work at Texas Tech University where he founded a clinical research institute, the Nutrition and Metabolic Health Initiative.

“There are lots of theories in psychology—self-determination theory, self-efficacy theory, cognitive behavioral theory—so how do we use these theories and translate that into tools that we use to motivate people?” he said. That is the question that his course aims to address.

The graduate course doesn’t require any pre-requisites and provides an unwavering client- focused approach to motivating and empowering people, Binks said, redefining the relationship between medical professionals and their clients, who benefit from having control and autonomy over their own health goals.

While techniques such as motivational interviewing are commonly taught in medicine and used to understand how to motivate an individual person specific to their needs, Binks said this class teaches so much more.

“A coach’s primary tool is questions,” he said, “because it’s about the person in front of you. We often, especially in health care, assume that we know everything and the patient doesn't. That’s the worst thing we can do.”

Kathryn Tadio, MS Nutrition ’18, is an adjunct professor in the Department of Nutrition and Food Studies and is taking the course as a nondegree student.

“I am counseling clients now, and I'm already learning how to apply this course material with them. Having this resource has been really beneficial,” said Tadio, a registered dietitian who works for Dietitian Live, a telehealth program.

The first assignment students receive is an improv assignment, allowing students to practice thinking and speaking on their feet, which is a great tool for a coach.

Students provided verbatim transcripts, and then used a dictation software to edit the scripts and analyze their own conversations.

One of the cons with the class is that students might think they’re just having a normal conversation because it appears so natural, Binks explained, it takes time to fully appreciate the depth of thought that a coach brings to each and every choice they make in that conversation.

“The assignment was so well thought out and it involved a lot of role playing and practicing what we're learning with fictitious clients. We were asking questions around people's triggers, for example, what makes them eat even when they're not hungry,” said Tadio. “That’s definitely something that I’d tiptoe around with actual clients, so it's good to practice with those questions now because it really lowers the risk of miscommunication or mistakes in the real world.”

The asynchronous aspect of the course provides an interesting real-life element, Binks said. Students practice their new skills in role play assignments.

“We’re online, but the assignments require the students go out into their personal world talking to their friends and family and coaching them,” said Binks. With these assignments, students learn and practice the necessary complex skill sets that they can then apply to pretty much any field they want.”

Tadio was pleased to have access to such a resource. “I’m really happy to see how George Mason’s nutrition department has grown since I was a student. Now they offer the registered dietitian track and courses like this one, which will make more well-rounded health care professionals.”

First-of-its-kind research identifies beneficial prenatal vitamins to reduce risk of infant death

First-of-its-kind research identifies beneficial prenatal vitamins to reduce risk of infant death Jennifer Pocock Thu, 01/30/2025 - 10:19

Assistant Professor of Global and Community Health Dongqing Wang publishes landmark analysis on the impacts of prenatal vitamins on mothers and newborns in the Lancet Global Health.

Dongqing Wang, PhD, MPH

Dongqing Wang, an assistant professor of Global and Community Health at George Mason’s College of Public Health, is pioneering research in prenatal nutritional interventions. His latest report identifies prenatal supplements that reduce health risks to small and vulnerable babies. This research was published in the prestigious Lancet Global Health journal and funded by the Bill and Melinda Gates Foundation.

Wang found that compared to folic acid and iron alone, a multiple micronutrient supplement led to a 27% lower risk of giving birth to “small vulnerable newborn types,” or babies who suffered from preterm birth, low birthweight, and small-for-gestational-age birth—the three groups most likely to result in infant death.

In the past, these birth outcomes were all treated as separate conditions. Wang, however, delves into emerging science to look at different combinations across the three outcomes. Low birthweight, for example, can occur because of a short pregnancy, and growth restrictions can lead to babies born too small for their developmental age.

“Small vulnerable newborn types may have distinct mechanisms, health impacts, and intervention strategies,” says Wang. “This work is the first to examine the effects of prenatal multiple micronutrient supplements and small-quantity lipid-based nutrient supplements on the emerging outcomes of small vulnerable newborns.”

Folic acid and iron have been used to support prenatal health since the 1970s. Wang explored the effects of two additional types of prenatal supplements on women in low- and middle-income countries: prenatal multiple micronutrient supplements (MMS), similar to a common multivitamin, and small-quantity lipid-based nutrient supplements (SQ-LNS), which provide caloric nutrition and fatty acids in addition to vitamins.

He found that nearly all of these vitamins conferred some type of benefit—and some of them were hugely beneficial.

“This study underscores the important promise of nutritional supplements in prenatal care in low- and middle-income countries,” says Wang. “In particular, the protective effects of prenatal multiple micronutrients on most small vulnerable newborn types, particularly those with the greatest mortality risk, strongly supports switching from iron and folic acid supplements to MMS as the standard care.”

Combining 16 different studies, Wang analyzed how prenatal nutrition correlates to the occurrence of small vulnerable newborns. He believes that the right prenatal supplements can help mitigate them. Since more than 90% of pregnancies resulting in low birthweight occur in low- and middle-income countries, including those in sub-Saharan Africa and South Asia, Wang focused this work on those regions.

The Lancet Global Health published "The effects of prenatal multiple micronutrient supplements and small-quantity lipid- based nutrient supplements on small vulnerable newborn types in low- and middle- income countries: a meta-analysis of individual participant data” in January 2025. Additional authors include Enju Liu, Nandita Perumal, Uttara Partap, Ilana R. Cliffer, Janaína Calu Costa, Molin Wang, Wafaie W. Fawzi, and more than 40 data contributors from all over the world who provided the individual participant data used in this landmark analysis.

George Mason advanced its rankings in nearly every online master’s degree program where it was included. The university is one of just five institutions in Virginia ranked in at least nine of the 13 categories where it is included, earning No. 1 rankings in four of those categories, more than any other university in the state for these categories.

“These rankings affirm that George Mason is a leader in Virginia in producing graduates for high-demand industries critical to the growth and prosperity of the commonwealth,” said George Mason President Gregory Washington. “We achieve these outcomes by partnering with industry leaders to develop academic programs that prepare graduates for a rapidly evolving workforce.”

A Leader for Military-Affiliated Students

With more than 4,700 students identifying as active-duty service members, veterans, or dependents, George Mason remains a vital resource for Virginia’s largest military-connected community. This year, approximately 20% of the university’s incoming freshman, transfer, and graduate cohorts have military connections, reinforcing the university’s reputation as a top destination for military-affiliated students.

George Mason earned the top spot in Virginia and nationally among public universities for its MBA program for veterans, and was first in Virginia and the Washington, D.C., metropolitan region for its master’s in nursing for veterans.

In September 2024, U.S. News & World Report ranked George Mason as one of the state’s best colleges for veterans. The university was also recognized with “Gold” status as a top Military Friendly University, underscoring its commitment to supporting those who have served.

“We are proud to serve a region that is home to a significant number of military members, veterans, and their families,” said Jennifer Connors, George Mason’s director of Office of Military Services. “At George Mason, we are committed to providing resources to support their unique needs. It is our duty to honor their service to our nation by empowering them to excel academically and professionally.”

Strong Performances Across Disciplines

In addition to its programs for veterans, George Mason’s online master’s programs excelled in several other areas: education, nursing, business, and engineering.

Northern Virginia boasts some of the nation’s top public school systems, and George Mason playing a significant role in that success. Approximately half of the region’s K-12 school administrators and an estimated one third of its teachers hold degrees or certificates from George Mason.

In the face of a national shortage of special education teachers, the university’s master’s in special education program stands out, ranking No. 1 in both Virginia and in the Washington, D.C., metropolitan area, and 5th nationally.

“We are thrilled to see our special education program recognized among the top five in the country,” said Ingrid Guerra-López, dean of the College of Education and Human Development. “This achievement is a reflection of our faculty’s remarkable expertise, dedication, and innovative approaches to preparing graduates to make a lasting impact in classrooms and communities.”

The School of Nursing within George Mason’s College of Public Health saw significant advancements in its rankings. The master’s in nursing program ranked No. 1 in Virginia, climbing up eight spots to 41st nationally (34th among public universities). Additionally, the Master’s in Nursing for Veterans program rose to 14th nationally (up from 18th), and 9th among public universities (up from 11th).

“Through hands-on clinical training and cutting-edge simulation technologies, our students are equipped with unmatched knowledge and cultural competencies,” said College of Public Health dean Melissa J. Perry. “Our graduates are among the most well-prepared nurses in the country.”

The Costello College of Business earned significant accolades, with its MBA for veterans program climbing to 30th (up from 41st) among public universities and 34th nationally (up from 50th). The MBA program also rose to 41st among public universities (up from 54th), 55th nationally (up from 74th), while its non-MBA program ranked 39th among public universities (up from 44th) and 56th nationally (up from 62nd).

George Mason’s College of Engineering and Computing saw two of its newest programs make strong debuts. The master’s in industrial engineering is best in Virginia and 10th nationally. The master’s in engineering for veterans’ program ranked 29th nationally. The master’s in engineering program climbed 22 spots to 45th nationally, and 38th among public universities (up from 51st).

The new master’s in IT for veterans program also made a strong first impression, ranking 21st nationally and 13th among public universities.

A Commitment to Excellence in Online Education

The strong performance of George Mason’s online programs aligns with the university’s mission to support students where they are. The flexible class offerings are a welcome boon to the university’s large number of post-traditional students, many of whom are professionals who continue to work full-time jobs and family responsibilities while pursuing academic goals to enhance their careers.

Marine veteran changed his life and seeks to reach others in need of positive direction

Marine veteran changed his life and seeks to reach others in need of positive direction Colleen Rich Wed, 11/06/2024 - 14:33

It was an epiphany of sorts, in the most unlikely time and place, but it changed the course of ��AV veteran Abidail “Abi” Estrada’s life—and the many lives he’s touched since.

At 19, after making “a lot of bad choices,” Estrada found himself sitting by a Northern Virginia road next to his broken-down car, reflecting on his future. This pivotal moment motivated him to leave behind his troubled past, join the U.S. Marine Corps, and eventually find his true calling in helping fellow veterans and others in need.

“I went off on myself,” recalled Estrada, now a proud husband, father, and U.S. Marine veteran of two tours in Afghanistan who is pursuing a master’s degree in social work. He asked himself what was wrong, wondering if this was truly the life he wanted, and whether he would continue down the same path forever.

This was just the impetus Estrada needed to break free from an unstable home environment that had him headed nowhere good. As a Guatemalan native, who was just 11 years old when his family arrived in the United States in 1998, Estrada longed for a better life, and after that moment of self-realization, enlisted in the U.S. Marine Corps, which allowed him to alter his own personal narrative.

Estrada’s first tour of duty in Afghanistan began with a stay in the volatile Helmand Province in May 2010, followed by another stint in the war-worn nation from 2013-14. It was extremely dangerous, but as a Marine sergeant and infantry squad leader, he took great pride in serving alongside his new brothers in arms. “I was doing something with purpose, something that was meaningful to me,” he said. “If I was going to die, I was going to die with a purpose.”

After eight years of service, Estrada left the Marine Corps in 2015. Hoping to get a higher-paying job to take care of his family, he enrolled at Northern Virginia Community College (NOVA), with the goal of transferring to George Mason to earn a four-year college degree. Hardly a great student while in high school, Estrada quickly found that he was no longer that same guy—he had matured through his military experiences.

He thrived academically, making the Dean’s List at NOVA before transferring to George Mason in 2017 and graduating from the College of Public Health with a bachelor’s degree in social work in 2019. His wife, Maritza, also a George Mason graduate, strongly encouraged her husband through it all.

When beginning his academic career, Estrada found that he had an innate desire to help others. He soon discovered his niche in assisting veterans and their dependents navigate the often-complicated GI Bill process, enabling them to receive the benefits were entitled to. Whether at NOVA or George Mason, Estrada supported fellow veterans by providing them opportunities to connect and share their military experiences with someone who truly understands.

Estrada’s dedication for helping others did not go unnoticed. Ryan Barnett, associate director of George Mason’s Office of Military Services, recognized Estrada’s potential and encouraged him to pursue social work.

“Abi has a heart of gold and a passion to help people and connect with them,” said Barnett, a fellow Marine veteran.

“The more I learn about the profession, the more I love it,” Estrada said.

Following his graduation, Estrada spent several years helping local youth, first as a youth counselor for Northern Virginia Family Services and then as an investigator of child abuse and neglect cases for Prince William County. Now as a 37-year-old father of three, he returned to George Mason this fall to pursue his master’s degree in social work, continuing his mission to serve his fellow veterans and others in need.

Estrada is grateful for the opportunities the United States has provided him. He said giving back is the least that he can do. “I’ve always loved and respected this nation,” he said. “It fed me and clothed me. What my birth nation couldn’t do for me, America did. That’s why I want to give back.”

George Mason REACHes for regional health policy solutions

George Mason REACHes for regional health policy solutions Nathan Kahl Fri, 11/01/2024 - 11:53

As the planet’s climate shifts, so too does the health of its inhabitants. Rising temperatures, wildfires, and worsening air quality are environmental and public health concerns.

With a new $3.69 million grant from the National Institutes of Health (NIH), the Research and Engagement for Action in Climate and Health (REACH) Center is set to tackle the urgent intersection of climate change and public health in the nation’s capital. ��AV is part of a team of institutions working on environmental health innovation that includes George Washington University (GWU), Howard University (HU), and the Environmental Defense Fund (EDF). The REACH Center will be directed by Susan Anenberg, professor and chair of the Milken Institute School of Public Health at GWU.

Jim Kinter, director of the Center for Ocean-Land-Atmosphere Studies and the Virginia Climate Center (VCC) at George Mason, sits on the REACH internal advisory board. VCC's interdisciplinary team of Mason experts conduct research on Virginia’s vulnerability and risks to the impacts of climate change in order to provide local decision makers with actionable climate information.

“Climate change is having negative impacts on public health, and projected future climate changes will only exacerbate those effects, most acutely felt in underserved communities," said Kinter. "The REACH Center serves a vital role in making data and information more accessible, more effective, and more useful for conducting research and co-producing equitable solutions to advance public health resilience. With George Mason experts working across several disciplines, the center has a unique and powerful capability to transform research and applications in public health, and the emphasis on community engagement will help translate findings into practical solutions.”

Lucas Henneman, an assistant professor in the Sid and Reva Dewberry Department of Civil, Environmental, and Infrastructure Engineering at George Mason, is leading a research project within the center studying climate policy in Washington, D.C. He’ll look at congestion pricing—charging a toll for vehicles traveling into a central part of the city—and the impacts on air pollution and local health. The D.C. government previously showed interest in such policies, and Henneman is working with researchers at George Mason and GWU along with a transportation advocacy group called Greater Greater Washington, who have deep ties in the D.C. government and interested community groups.

“The big thrust is that there's all this useful data out there that can be used to better protect public health from impacts of climate change," said Henneman, "but how do we make that data useful to stakeholders like researchers, community groups, and local governments?”

The co-location of these entities in the Washington, D.C., region allows them to work with the federal and regional governments, as well as other experts in public health and big data. The REACH Center will also look broadly at the implication of health and climate data.

“How do you process air pollution and public health information in a way that can be useful for different stakeholders,” said Henneman. “In D.C., for example, you have wards, neighborhoods, and census tracts, and you might have different amounts of data in each of those geographies and different stakeholders would want to see information about their locations. So, how do we interpret the outcome of a policy on these different geographic boundaries?”

Daniel Tong, director of George Mason's Cooperative Institute of Satellite and Earth System Studies, is co-directing REACH’s Exposure Assessment Core. He gave an example of how even far-flung incidents can affect local populations, and why it’s important to understand this impact. “Rising temperature and droughts bring more wildfire smoke and every-day air pollution to cities like Washington, D.C.," said Tong, who is also an an associate professor in the College of Science. "It is critical to measure how these changes harm people’s health. The exposure core will leverage George Mason’s world-renowned expertise in atmospheric and climate sciences to support health researchers and practitioners to understand these impacts.”

Jenna Krall, an associate professor in George Mason's College of Public Health, also brings expertise to the project, further emphasizing the interdisciplinary aspects.

The NIH Climate Change and Health Initiative (CCHI) funded 16 new exploratory research centers in September, including the REACH Center. These centers will support the development of innovative transdisciplinary research into the complex impacts of climate change on health.

Henneman noted that, in the long-run, this could mean more opportunities for George Mason researchers to study how regulations can consider the intersection of climate change and health.

New study shows that university students experienced increased psychological distress during COVID-19, but utilized fewer support services

New study shows that university students experienced increased psychological distress during COVID-19, but utilized fewer support services mthomp7 Wed, 10/30/2024 - 07:09

Underrepresented students, particularly women of color, were less likely to receive mental health services during the pandemic.

PhD in Public Health candidate Elaine Russell and her mentor Kenneth Griffin, a professor in the Department of Global and Community Health, in ��AV’s College of Public Health, worked with Tolulope Abidogun, also a PhD in Public Health student, and former Global and Community Health professor Lisa Lindley, now of Lehigh University, to analyze data from the American College Health Association National College Health Assessment (ACHA-NCHA III) in an effort to understand how university students’ mental health needs changed during the COVID-19 pandemic.

PhD in Public Health candidate Elaine Russell studied how university students’ mental health needs changed during the COVID-19 pandemic.

“More U.S. college students suffered from mental health concerns during the pandemic, but fewer received necessary mental health treatment,” says Russell.

This study is the first to use a national dataset to examine changes in university students’ psychological well-being and their utilization of mental health services from pre-COVID-19 to peak pandemic. Russell and the research team found that, consistent with prior research related to diverse populations, racial/ethnic, gender, and sexual minority groups were at a greater risk of suffering from poor mental health during the pandemic. Additional findings revealed that, during the pandemic, students of color, especially female students of color, were less likely to receive mental health services.

“When developing innovative approaches to improving mental health outcomes on college campuses, it is important to be culturally sensitive and understand the diverse needs of the specific student population,” says Russell.

The study used data from before the COVID-19 pandemic (Fall 2019 and early Spring 2020) and during the pandemic (Spring 2021) to examine mental health symptoms and utilization of mental health services among university students. The sample was limited to full-time undergraduate students aged 18-24 attending four-year universities in the United States. In addition to analyzing the entire sample of university students, the team examined demographic subgroups based on race/ethnicity, sexual orientation, and gender identity.

Several validated psychological testing scales were used in the study to indicate students’ self-reported levels of psychological distress, loneliness, overall stress, psychological well-being, and resilience. Additional survey questions asked about COVID-19 specific stressors, including the students’ concern over themselves or their loved ones getting COVID-19 and being unable to spend time with the people they care about due to the pandemic lockdowns. Students’ use of mental health services within the 12 months preceding the survey was also assessed.

“These findings are important to better understand sub-groups who disproportionally suffer from severe psychological distress but may not be accessing the necessary care,” the study reports. While issues such as a lack of access to mental health services and discrimination within the health care system are undoubtedly factors in students’ reluctance to seek mental health care, the stigma surrounding mental health is also prohibitive.

“Improvements in mental health resources must also address stigma and empower students to access necessary care,” Russell says, specifying the use of peer health educators and making efforts to normalize mental health treatment may be effective prevention strategies.

Russell concludes by calling for future research to increase understanding of the barriers to mental health service use among high-risk university students.

“Impact of the COVID-19 pandemic on university students’ psychological distress, well-being, and utilization of mental health services in the United States: Populations at greatest risk” was published online in Frontiers in Public Health in October 2024.

New research utilizes machine learning to address social isolation among alzheimer’s caregivers mthomp7 Thu, 10/10/2024 - 13:22

A new study from the College of Public Health at ��AV, led by Professor Janusz Wojtusiak and Health Services Research doctoral candidate Ghaida Alsadah, explores the use of machine learning to predict social isolation among caregivers of individuals with Alzheimer’s disease and related disorders.

This research, which has been selected for funding by the Commonwealth of Virginia's Alzheimer's and Related Diseases Research Award Fund (ARDRAF), marks a significant advance in leveraging artificial intelligence (AI) to address a critical public health issue.

Professor Janusz Wojtusiak uses machine learning to predict social isolation among caregivers of individuals with Alzheimer’s disease and related disorders.

Alsadah has played a pivotal role in this study, contributing her expertise as a doctoral candidate to develop and refine machine learning models. These models analyze data from the Health and Retirement Study (HRS), National Health and Aging Trends Study (NHATS), and Behavioral Risk Factor Surveillance System (BRFSS) to identify and predict social isolation trajectories among caregivers. The study’s key finding is that AI-driven methods offer a novel approach to detecting social isolation, potentially leading to targeted interventions.

“This research is groundbreaking in its application of machine learning to predict social isolation among caregivers, an area previously underexplored,” said Wojtusiak. “The potential to develop AI-based interventions could significantly enhance the well-being of caregivers who often face profound social and emotional challenges.”

The study aims to construct predictive models for social isolation, adapt them for Medicare claims data, and simulate their application across large populations. The goal is to create a framework for AI-based interventions to address loneliness among caregivers effectively.

The innovation of this work lies in its use of machine learning to analyze and predict social isolation—a new approach with the potential to transform current understanding and interventions. Wojtusiak and Alsadah’s research is set to significantly impact health informatics and caregiver support. “Predicting Social Isolation Among Alzheimer’s Caregivers Using Machine Learning” will be published in an upcoming issue of a leading health informatics journal, emphasizing the importance of innovative approaches to complex public health challenges.

Additional contributors include College of Public Health alumna Mary Louise Pomeroy, a postdoctoral research fellow at Johns Hopkins University, who provided valuable expertise on social isolation and relevant datasets.

As the supervisor of Volunteer and Partner Services within the county’s Department of Family Services (DFS), this ��AV alumna plays a leading role in providing critical services to children and their families through programs that are powered entirely by volunteers.

“I like to call Volunteer and Partner Services the best-kept secret in DFS,” she said. “We’re providing so many resources to families and communities.”

Those resources include their popular holiday assistance program, Adopt-a-Family; the Befriend-a-Child mentoring program; and body safety classes for children offered in the public schools. Last year, the Body Safety Program alone served 15,000 children.

“It’s been really nice to see the impact that we’re making,” Carrico said. “Prevention is definitely where we’re going to move the needle for child welfare.”

When not managing four full-time staff members, almost 100 volunteers, and leading the county’s child welfare mandated reporter training for agencies ranging from county police departments to the CIA, Carrico is also the official handler for county facility dog Rylynn.

Carrico was working with Manassas City when she heard of a colleague who worked with a certified service dog and broached the idea with her supervisor. When she learned they could have one only if the dog were free, Carrico didn’t give up. After much research, her perseverance paid off. She found Canine Companions, an organization that offers trained service dogs to organizations and individuals free of charge, and Rylynn entered her life.

“Rylynn is actually the only facility dog at a family services or social services agency in the whole country,” Carrico said. Rylynn attends events and is certified to accompany children to the witness stand when they must testify in court. “She doesn’t have a vest, a badge, a gun. She’s not intimidating, and it’s very rewarding for a family or for a child to know that Rylynn is here for them, with no other agenda.”

Carrico hopes her experience with Rylynn—and her determination to find a way to make it happen—will help pave the way for more agencies nationwide to acquire their own facility dogs.

“Children will disclose when they’re ready, but also when they’re comfortable. And sometimes it’s on us as the professionals to help make sure the environment is comfortable for them.”

A licensed social worker, Carrico has been with Fairfax County in a full-time role since 2020, but her entry into the world of child welfare started long before that—and included a pivotal stop at ��AV.

Born and raised in Northern Virginia, Carrico’s first memories of the university came at an early age, when she attended Camp Mason at the Fairfax Campus. When it came time to think about getting her master’s in social work, the choice was easy.

“Mason felt like a second home,” she says. Encouraged by the Department of Social Work faculty in the College of Public Health, Carrico decided to additionally pursue her licensure.

Carrico cites Valerie Cuffee, a former long-time social work faculty member who also had child welfare experience, as a particular influence. “Having a professor who was sharing her real cases and what she learned from them, and the mistakes she made—that was invaluable.”

Equally invaluable were the many internship opportunities the university offered her, including at a homeless shelter and with Loudoun County’s Department of Family Services. “What really resonated with me from being a student into being a professional is…how enriching my internships were.” She’s since paid the opportunities forward by frequently hiring George Mason students as interns.

It all comes back to her desire to make a difference, whether she’s offering in-person training or sitting quietly while Rylynn comforts a child in distress. “My heart really lies in wanting to do more.”

Gut Bacteria may be Linked to Obesity in Peri- and Post-menopausal Women

Gut Bacteria may be Linked to Obesity in Peri- and Post-menopausal Women Kelly Hansen Tue, 08/13/2024 - 15:57

Cara Frankenfeld studies the connection between gut bacteria and obesity.

Extra pounds on peri- and post-menopausal women may be connected to gut bacteria living in the intestinal tract, according to a recently released study co-authored by a ��AV alumna and professor.

“Gut bacteria profiles are incredibly complicated and very diverse across people,” said Cara Frankenfeld, a global and community health professor at George Mason.

Women whose gut microbial communities can’t turn daidzein, a compound found in soy, into something called O-desmethylangolensin are more likely to be overweight, according to a study published in Maturitas.

Daidzein has been of some interest to scientists for a while because it is structurally similar to estrogen and can possibly elicit weak estrogen-like responses in peri- and post-menopausal women who tend to have lower estrogen levels, Frankenfeld said.

There are subsets of the population who don’t produce certain compounds, in this case, ODMA.

“We can tell something about people’s gut bacteria based on the presence or absence of these compounds,” she said.

The idea is that certain gut bacteria profiles are associated with certain health outcomes. Peri- and post-menopausal women who have a profile that can’t produce ODMA are in a group that’s more obese, Frankenfeld said.

The cross-sectional study examined 137 peri-menopausal and 218 post-menopausal women who consumed at least three servings of soy per week. They were identified as ODMA producers or nonproducers through urine samples.

Studies have examined other age groups, but the results vary, Frankenfeld said, so it may be an age group or a hormonal status-specific condition.

It could be that producers of ODMA may be more at risk for other conditions, she said, but researchers aren’t yet able to make recommendations to women who may fall within this group.

“We wouldn’t want people to try and become producers [of ODMA],” Frankenfeld said.

Scientists do know there is an obesity–gut bacteria relationship, she said, but more research is needed to fully understand whether and how gut bacteria influence obesity, or whether it is vice versa, or both.
