“Imagine living in a place where you can comfortably send your child and their friends on a safe route to your local library on foot or by bike. How about being able to engage in physical activity by simply accessing an expansive network of trails that might connect parks to local suburbs? This is what walkability looks like—and walkability is public health,” said social science researcher Iulia Fratila, an assistant professor in the Department of Global and Community Health at �鶹��Ƶ.

Fratlia participated as a cohort member of the 2025 Virginia Walkability Action Institute (VWAI) and was awarded $9,000 in funding to enhance a local park in Alexandria, Virginia. In partnership with the City of Alexandria Department of Recreation, Parks and Cultural Activities (RPCA), Fratila and third-year undergraduate social work student Bryce Neuman devised the plan for the Alexandria City Ben Brenman Park project, which aims to encourage walkability, promote physical activity among community members, and improve access to fitness.

Fratlia emphasizes the role of partnerships in bringing sustainable change to fruition. “A partnership like this is a win for everyone involved," she said. "Academic researchers bring knowledge and expertise on the science that shapes health outcomes and the potential prevention efforts and the governmental agencies can bring resources and design structures that support health-promoting landscapes and decision-making.”

The goal of the Ben Brenman Park project is to upgrade a trail segment in the south side of the park that has been underdeveloped and underutilized. The anticipated result is more walking and community engagement, healthier residents in the city of Alexandria and surrounding areas, and addressing health and recreation access gaps.

“We need to make sure we are creating and enhancing built environments and infrastructure that make healthier habits like walking and biking a possibility for all,” said Fratlia.

Neuman joined the Ben Brenman Park project to explore her interest in the built and natural environment as an important factor of public health as well as connections to macro-level social work dimensions. Together, Fratlia and Neuman developed the project’s action plan and strategic goals that guided them through the project proposal and implementation process.

Fratlia attended the farmers' market held at the park to distribute QR codes linking to the survey, and the RPCA emailed the survey to the city residents via their newsletter. These data collection methods garnered more than 400 responses. Based on the survey responses, the community identified priorities, including planting native trees and plants and installing adult fitness equipment in the park. Subsequently, the RPCA Urban Planning team created a plan outlining the proposed layout for exercise equipment and tree plantings.

“I am looking forward to being able to see the final product implemented at the park and see that positive change. I’m particularly excited about the addition of native wildlife around the park, and I hope the people who live near and visit the park also appreciate the changes,” said Neuman.

In addition to the pitch and execution of the Ben Brenman Park project, the VWAI program, in partnership with Equitable Cities LLC, involved attending distance learning modules and in-person workshopsfocused on topics such as Placemaking and Tactical Urbanism, the Economic Impact and Sustainability of Active Transportation Investment, Inclusive Community Engagement, Safe Routes programming, and Complete Streets initiatives. This experience allowed Fratila and Neuman to apply public health principles to a real-world built environment project while engaging directly with community members to address their needs and priorities.

The park enhancement project, which has officially been named a case study by the VWAI, is scheduled to be completed in early 2026 and will be installed by the City of Alexandria Department of Recreation, Parks and Cultural Activities. The VWAI is a program of the Virginia Department of Health and is supported by the Centers for Disease Control and Prevention.

“This experience helped solidify my interest in policy and program evaluation for maternal and community health, which is an area of interest I hold dear to my heart,” she explained. “I strengthened my skills in policy writing and stakeholder engagement, which are all important skills for working in public health policy and advocacy.”

For Addo-Boateng, a first-generation student who graduated in May, her practicum provided a strong foundation for a career in the public health field. She participated in research, evaluation, and communication initiatives at Culture Care Collective—a health equity program aimed at integrating community health workers into university and clinical environments to improve care for underserved populations. During her time with the collective, she wrote a policy brief and a case study, supported the design and analysis of qualitative data on program impact, and co-authored a manuscript summarizing her findings.

Beyond her practicum, Addo-Boateng worked as a graduate research assistant, supporting research led by CPH faculty Rochelle Davidson Mhonde and Michelle S. Williams on fertility desire among women living with HIV. The role allowed her to sharpen her writing, data analysis, and time management skills, while also learning how to communicate research findings to both academic and non-academic audiences.

In addition to supporting faculty-led projects, Addo-Boateng pursued her own research at George �鶹��Ƶ, conducting a policy analysis for the March of Dimes on closing Medicaid postpartum care gaps and addressing maternal mortality disparities. She evaluated three policy approaches through the lenses of effectiveness, efficiency, and feasibility, with an emphasis on justice-oriented solutions, and presented her findings in testimony and peer presentations on how strategic policy changes could reduce costs, strengthen care coordination, and improve maternal health outcomes.

She further demonstrated her skills at the national level by participating in the 2025 National Case Study Competition in Health Education, where her team earned the silver award for their solution to address rising rates of sexually transmitted infection among young adults.

“I learned how to put research into actionable policy tools that will resonate with diverse stakeholders,” explained Addo-Boateng. “I also learned how important it was to be adaptable, especially when working on interdisciplinary teams and navigating real-world timelines. In my case, I was completing full time studies as a graduate student, working on my research assistant position with my professor Dr. Rochelle Davidson Mhonde, and contributing to my practicum responsibilities.”

Addo-Boateng says she is incredibly grateful for the opportunities she had at the College of Public Health, especially the mentorship and hands-on experiences that helped bring everything together. She believes her time at �鶹��Ƶ has truly prepared her to step into the next phase of her career with confidence and clarity.

For fellow students, she offers this advice, “Choose a practicum that aligns with both your values and your long-term goals. Also, don’t be afraid to step outside your comfort zone, as it’s often where the most growth happens! Lastly, take initiative because from my personal experience, my practicum was a launchpad into getting experience in the public health field.”

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 �鶹��Ƶ’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.

Use of skin care products is associated with exposure to phthalates and phthalate-replacement chemicals in young children, according to the new and first-of-its-kind study at �鶹��Ƶ's College of Public Health.

A new study led by primary investigator Michael S. Bloom, professor in the Department of Global and Community Health at George �鶹��Ƶ’s College of Public Health, has found that use of skin care products including lotions, hair oils, hair conditioners, ointments, and sunscreen is associated with higher levels of phthalates in children’s urine. The associations depend in part upon the child’s racial and ethnic identity and their sex as assigned at birth. The study was co-authored by two George �鶹��Ƶ Master of Public Health alumni, Juliana Clark and Kelly Garcia.

“This is the first study to suggest that different skin care products used by young children may differentially increase exposure to endocrine-disrupting phthalates and phthalate replacements in young children,” said Bloom.

Phthalates and phthalate-replacement compounds are endocrine-disrupting chemicals, meaning they may interfere with the body’s hormones. Exposure to these chemicals in early childhood has been associated with neurodevelopmental, reproductive, and metabolic disease concerns in previous studies. Some of these chemicals are often used as carriers for the active ingredients in skin care products; others may be used in plastic packaging.

The study collected medical data from 630 children between the ages of 4 and 8 from 10 different sites across the United States, including a clinical examination and a urinalysis. The child’s parent or guardian was also asked to complete a survey within 24 hours prior to the child’s examination, which included questions regarding the child’s sociodemographic information (race/ethnic identity, sex assigned at birth, etc.). It also asked parents to list all the skin care products, including lotions, soaps, shampoos, oils, and cosmetics, that were applied to the child’s skin in the 24 hours prior to their examination, with as much specificity as possible regarding the product type and brand or generic name.

“We found associations between recent use of different skin care products and higher concentrations of phthalate and phthalate-replacement compounds,” said Bloom. “There were different relationships between the use of skin care products and the endocrine-disrupting chemicals in children depending on their racial and ethnic identities and their sex assigned at birth. We also found that distinct patterns of using multiple skin care products were predictive of higher concentrations of phthalates and phthalate replacements.”

While Bloom and his team say that further studies are necessary to confirm these findings, the results suggest that children in different racial and ethnic groups may experience different levels of risk for exposure to phthalates. In particular, they found the highest levels of phthalates and phthalate replacements in the urine of non-Hispanic Black participants. The differences may correlate to brand availability and preferences, methods and timing of product application, and/or the frequency of use by children with different racial and ethnic identities.

“The results can inform policies to address the use of endocrine-disrupting chemicals in skin care products that may be used on children and to help advise parents’ decisions about using products to limit their children’s exposure to potential developmental toxicants,” said Bloom.

“Impact of skin care products on phthalates and phthalate replacements in children: the ECHO-FGS” was published online in Environmental Health Perspectives in September 2024. This research was funded by the U.S. National Institute of Health (NIH) Environmental Influences on Child Health Outcomes (ECHO) study.

New research describes the leisure motivations that underpin young U.S. adults' recreational cannabis use

New research describes the leisure motivations that underpin young U.S. adults' recreational cannabis use Mary Cunningham Mon, 06/10/2024 - 11:40

Iulia Fratila, PhD

As of 2024, 24 states including Virginia, Maryland, and Washington, D.C., have legalized the adult recreational use of cannabis. As laws change, citizens' perceptions of the drug and reasons for using the drug have also shifted. In 2020, 34.5% of adults aged 18–25 reported using cannabis in the previous 12 months, according to the Substance Abuse and Mental Health Services Administration. Health experts seek to better understand the broader implications of legalization and individuals’ motivations and attitudes related to cannabis use.

Iulia Fratila, assistant professor in �鶹��Ƶ’s College of Public Health

New qualitative research by Iulia Fratila, assistant professor in �鶹��Ƶ’s College of Public Health, and Liza Berdychevsky, associate professor at the University of Illinois Urbana–Champaign, describes in what ways young adults (aged 18–30) view cannabis as a recreational and leisure pursuit.

“Recreational cannabis legalization and liberalization is shifting across U.S. states. More holistic approaches to understanding perceptions of cannabis benefits and leisure motivations are scarce due to the longstanding criminalization of cannabis,” said Fratila, the principal investigator. “This research provides novel insights into cannabis users' leisure motivations of use and perceived benefits, which can be leveraged strategically in public health and drug education efforts in the societal transition from criminalization to normalization and commercialization trends concerning cannabis.”

Participants in Fratila and Berdychevsky’s study suggest cannabis can offer a leisure state of mind (e.g., experiencing flow, relaxation, and meditative state), as well as represent a leisure pursuit reserved for free time (e.g., using cannabis as a reward for free, post-obligations time outside of daily demands). Additionally, participants described how cannabis serves as a leisure activity itself (i.e., the act of getting high) and/or as an activity that accompanies other leisure pursuits and socialization (e.g., getting high and going to the movies), while providing pleasurable outcomes (e.g., feeling enjoyment, engaging in humor, enhancing senses).

“Participants discussed the ways that their recreational cannabis consumption represents a controlled and calculated risk-benefit leisure choice that is successfully managed for their overall well-being. Their narratives highlight that this perceived leisure pursuit does not necessarily interfere with their otherwise productive lives,” said Fratila.

These insights can inform harm reduction approaches to cannabis education that may be more effective considering the cannabis legalization and liberalization landscape. Health educators and health promoters can discuss cannabis risks and potential negative health outcomes while acknowledging the desired benefits cannabis users anticipate.

Fratila warns about the impacts of widespread legalization and the emerging recreational cannabis markets, which highlights another meaningful implication connected to the study findings. “Under prohibitory regulations, recreational cannabis use has been explicitly framed as deviant, criminal, harmful, life-wrecking, and void of any potentially desirable leisure qualities (e.g., pleasure, socialization). This study showcases the cannabis users’ understanding of cannabis as normative recreation and the anticipated leisure benefits,” said Fratila.

She further explained, “However, this is a cautionary tale because these desirable qualities may be easily exploited. More specifically, society may be facing a new conundrum with the commercialization of recreational cannabis as the switch from criminalization to commercialization overly simplifies and glamorizes the leisure meanings of cannabis for profitable gain.”

Public health experts and scholars will need to be at the front lines, in collaboration with other fields, to monitor how cannabis is repositioned and accommodated in a cannabis-friendly society, according to Fratila. Specifically, it will be important to spearhead effective health promotion efforts that minimize any related harms and maximize well-being.

This was a qualitative research project utilizing hermeneutic phenomenology, a research method to study how experiences affect everyday practices, and in-depth interviewing with 16 individuals (ages 18–30) living in the U.S. states with legalized recreational cannabis.

“Phenomenological Exploration of Young Adults’ Recreational Cannabis Use Experiences and Associated Leisure Meanings” was published in the Journal of Leisure Research in June 2024. This research was not funded.
