Public health students partner with MALAMA Aquaponics on their research project.

Modeled after a professional academic conference, the Hōʻike, now in its 10th year, highlights student projects developed through partnerships with community organizations. Students work in teams to translate health promotion theory into practice—building relationships, conducting interviews, analyzing qualitative data and sharing findings grounded in community perspectives.

Guided by faculty Jane Chung-Do and David Stupplebeen, students collaborate directly with local partners to address pressing public health priorities.

“Student projects like these help connect students with the community, provide meaningful contributions to the work of community-based organizations, and help perpetuate the vision and mission of the Department of Public Health Sciences,” said Stupplebeen.

Partnerships that make an impact

The community partners of the Fall 2025 semester included ,, , and . Student projects examined a wide range of topics from factors related to delayed prenatal care among Native Hawaiian and Pacific Islander women to coalition engagement in fall prevention efforts and expanding training pathways for Native Hawaiian healthcare practitioners.

For many students, the Hōʻike marked their first formal research presentation, strengthening skills in collaboration, analysis and professional dissemination.

“Having the opportunity to work so closely with a community of practice allowed me to uplift their values during this project, all while reflecting on my own position as a researcher,” said Shanda Shamela Delos Reyes, a graduate student in the course. “The hōʻike itself was a practice of reciprocation, allowing us to share the community’s data back to them.”

“This invaluable learning opportunity is made possible by the dedication of our community partners. We are deeply grateful for their tireless service to 鶹ý and for welcoming our students into their vital work,” said Chung-Do.

“The students approached the project with diligence and professionalism, and delivered valuable data that will guide us in designing and implementing effective interventions for our members and the broader community,” said Lucie Tam, clinical coordinator, Quality & Performance Improvement, Quality Management at HMSA. “We look forward to partnering again on future initiatives!”

The Hōʻike reflects DPHS’ continued commitment to experiential learning, community engagement and advancing health equity statewide.

Challenging the traditional approach to pregnancy care which focuses solely on mothers’ behaviors, new research from the UH ԴDz and international partners highlights the significant and often underrecognized role of fathers’ health and well-being in shaping pregnancy and child outcomes. The study was recently published in .

“The more we look, the more we find important contributions from fathers, including many factors traditionally believed to be solely the responsibility of the pregnant person, such as weight status, substance use or being an older parent,” said Jonathan Huang, lead author of the study and assistant professor at the in the . “In some cases, paternal contributions are even larger than their maternal counterparts and several are related intergenerationally to the fathers’ own upbringing.”

A framework for preconception health

This transdisciplinary review uses evidence from biological, behavioral and social sciences to create a framework for men’s role in preconception health. The findings show that a man’s early life experiences—including stress, physical and mental health, environment and education—influence his health during reproductive years. These factors can, in turn, affect his partner’s health and health behaviors (such as prenatal care) before and during pregnancy, as well as having direct biological effects on the developing infant.

The research addresses ethical concerns, noting that placing all responsibility for a child’s future health on the birthing parent reinforces gender biases. Furthermore, the researchers emphasize that racism and colonialism have disrupted family and community roles for many Black and brown men, creating barriers to addressing their health needs. This disruption underscores the need for culturally grounded approaches, which are particularly effective for Native Hawaiian and Pacific Islander men.

“Policies and programs are needed to strengthen family and community bonds while centering the health and well-being of Ա [men] within their cultural roles. Native Hawaiian and Pacific Islander men are less likely to engage in Western-based health interventions than their female counterparts, but are more responsive to culturally grounded approaches,” said Keaweʻaimoku Kaholokula, co-author and chair of the Department of Native Hawaiian Health in the .

Improving the health of Hawaiian Ա

Kaholokula stated that the traditional concept of Hale Mua—a cultural space for men—offers a blueprint for improving the health of Hawaiian Ա by creating safe spaces for mentorship, life instruction, emotional regulation and the transmission of cultural values, which reinforces their kuleana (responsibility) to family and community.

The researchers emphasize that policymakers, public health agencies, clinicians, researchers and men themselves all have a role in improving preconception health. Investing in the wellbeing of boys and young men is key to reducing health disparities and improving outcomes for future generations.

Huang added, “Raising awareness about the importance of men’s health does not diminish the critical importance of women and pregnant persons’ well-being. Rather it serves as a collective call-in to ensure that men and partners are equipped to be supportive partners, allies and caretakers before, during, and long after pregnancy.”

The research team includes collaborators from the continental U.S., the United Kingdom, New Zealand and Singapore. A companion study highlights the work of the international Core Indicators for Preconception Health and Equity (iCIPHE) Alliance in improving how preconception health is measured and monitored.

outrigger canoe paddlers

A University of 鶹ý at ԴDz study confirms that outrigger canoe paddling is far more than a state team sport. It’s a way of life that supports physical, emotional, cultural and spiritual health for paddlers in 鶹ý.

Related UH News story: High canoe-paddling rates among NHPI could help health outcomes

The study, published in , examines paddling through a public health perspective. It was led by Simone Schmid, a former postdoctoral fellow and current adjunct assistant professor in the Thompson School of Social Work & Public Health’s (DPHS), as well as the director of strategy, impact and research at AccesSurf 鶹ý in collaboration with other DPHS authors, the 鶹ý State Department of Health and AccesSurf 鶹ý.

While previous UH research documented paddling’s physical benefits and participation patterns among Native Hawaiian and Pacific Islander communities, this study uniquely centers paddlers’ voices to explore the cultural, spiritual and community meaning that sustains long-term participation.

Centering paddlers’ voices

“As a paddler myself, having benefited from this physical and cultural activity and community in more ways than I can express, we did this work to capture what is already known in the community,” Schmid said. “It is just one piece in the puzzle of overall efforts and goals to support past, current and future paddlers. And one step in my journey of getting canoe club membership covered by health insurance.”

outrigger canoe paddling

The research team analyzed open-ended survey responses from 362 paddlers statewide who answered: “What does outrigger canoe paddling mean to you?” Almost half (47%) identified as Native Hawaiian; 65% were female. Responses revealed multiple layers of meaning, from physical health, stress relief and teamwork to family traditions, pride, connection to the ocean and ʻāina, cultural heritage and spirituality. Researchers adapted a social-ecological model to include a spiritual perspective.

Many paddlers reflected on ancestry and traditions. Ann Yoshida, paddler and community author with AccesSurf 鶹ý said, “Paddling across the world representing 鶹ý and the U.S., I felt connected to my island home and culture because my ancestors knew through navigation that the water was our highway to connect with the world. I knew if I was in water, I was home and I never felt alone. This power pushed me to live my extraordinary life.”

Cultural ties drive long-term participation

The study found cultural ties, rather than health goals alone, might motivate long-term participation. Paddling connects people to their health, ancestors, environment and sense of purpose. Findings have been shared with canoe clubs and public health partners to explore how paddling can support chronic disease prevention and community-based activity programs.

The study also received international recognition, with Schmid and co-authors named finalists for the , ranking among the top five Early Career Research papers of 2025.

“We are very proud to see the global dissemination of this important work from 鶹ý around strengths-based public health promotion, relevant to our communities,” said Tetine Sentell, DPHS professor and study co-author. Other DPHS authors include Carrie Soo Hoo, Catherine Pirkle, Michael Phillips and Mika Thompson.

Windward District teachers
Windward District CTE high school teachers gather for the first PH 101 training.

With 鶹ý facing a critical shortage of public health professionals, the University of 鶹ý at ԴDz’s is strengthening the public health workforce pathway—starting in high school classrooms.

Lightbulbs go off when participants realize how much public health shapes their daily lives.
—Yuka Polovina

The 鶹ý State Department of Education (DOE) offers a Career and Technical Education (CTE) Health Services pathway that includes a focus in public health, but only five schools statewide currently offer it. Limited awareness of public health careers among students—and limited familiarity with foundational public health concepts among teachers—have slowed expansion.

To help address this gap and increase the number of schools offering the pathway, Yuka Polovina, a faculty member in the (DPHS) at the Thompson school, developed “” (PH101-CTE). The workshop builds awareness of public health careers and equips educators with foundational concepts and classroom strategies, showing how public health principles can be integrated into lessons, activities and assessments.

“When I meet students who are interested in health fields, more often than not they say it’s because they want to help their communities,” said Polovina, who also serves as a workshop instructor. “It then surprises me when they say they want to become a nurse or doctor. Few know that public health is another powerful way to make an impact, and once students learn about it, they get excited.”

Real-world learning in action

The first PH 101 training, held in October 2025, brought together Windward District teachers in health services and agriculture pathways. Organized by Windward District CTE Resource Teacher Trisha Kim, the workshop highlighted connections between sustainability, food systems and public health.

“This is the best form of teacher professional development,” said Kim. “We are grateful for our partnership and the positive impact for our Windward District students.”

The day included a session at Kailua High School, facilitated by Polovina, and a site visit to the . The visit was led by Jane Chung-Do, acting chair of DPHS, along with Ilima Ho-Lastimoa and Ted Radovich from the College of Tropical Agriculture and Human Resilience (CTAHR). Participants learned about the , offering a hands-on and place-based example of public health in practice.

“Lightbulbs go off when participants realize how much public health shapes their daily lives––from the clean air we breathe to the simple fact that we don’t have to boil water before drinking it,” said Polovina. “They immediately see how their students will connect to it too.”

The PH 101 training is open to DOE CTE teachers statewide, with another session tentatively planned for this spring. Teachers interested in participating can request a workshop by emailing hiphwork@hawaii.edu.

This initiative builds on efforts from the and is supported through collaboration with the 鶹ý State Department of Health’s Public Health Infrastructure Grant.

Kauilaonālani Tengan is inspired to encourage greater participation from Native Hawaiian, Pacific Islander and Filipino communities in diabetes clinical trials to ensure research better reflects the populations most affected by the disease.

Leave your assumptions and biases at the door and engage these communities with aloha.
—Kauilaonālani Tengan

He is translating that goal into practice through applied research. A master of science student in epidemiology at the University of 鶹ý at ԴDz , Tengan was part of a study team at The Queen’s Health Systems (QHS) whose findings were published in in the study Exploring Diabetes Clinical Trial Participation: A Diverse Group Interview Study.

“I have a family history of cardiometabolic diseases and I remember visiting extended family who had to fly from Molokaʻi just to receive quality care here on Oʻahu,” he said. “This [experience] instilled in me a desire to learn more about health issues so prevalent in our islands and contribute to innovative solutions.”

Research findings and lessons learned

While at QHS, Tengan split his time between health equity research and clinical data management, utilizing electronic medical records to address research questions. He helped conduct interviews with 56 hospitalized patients to explore what motivates—or prevents—patients from joining diabetes clinical trials.

Although 84% expressed willingness to participate, most had never been asked. Barriers included mistrust, concerns about medication risks, and lack of understanding, while many Native Hawaiian and Pacific Islander participants cited family and community benefit as key motivators.

“Engaging face-to-face with people in a clinical setting humanized health data for me,” Tengan said. “It reminded me that these are people, not statistics. I realized that my work has a lasting impact, so it is my responsibility to do things in a pono manner.”

Tengan hopes to carry these lessons forward. “Leave your assumptions and biases at the door and engage these communities with aloha,” he said. “It is vital that we do work in an ethically and culturally nuanced way because there are real world impacts in the data that we publish.”

The study was part of an Food and Drug Administration-funded project at The Queenʻs Medical Center, in collaboration with the UH ԴDz , and clinical partners. also found that Native Hawaiian and Pacific Islander participants are consistently underrepresented in U.S. clinical trials.

“Kauilaonālani’s perspectives and real-life application from quantitative analyses are so important to building collective public health,” said Tetine Sentell, public health professor and study co-author.

Kauai Community College campus

鶹ý faces a significant public health workforce shortage that far exceeds the national average, leaving rural communities especially affected by limited public health resources and academic pathways into the field.

To help fill this gap, a three-course public health certificate offered by was developed and launched in fall 2020 in partnership with the University of 鶹ý’s (DPHS) and the Department of Health’s Kauaʻi District Health Office (KDHO). Nearly six years later, 72 students—including high school early college participants—have completed the program, gaining foundational knowledge and credits transferable to a at UH ԴDz.

Early college credits, pathway to a degree

The certificate introduces foundational concepts through PH201: Introduction to Public Health, PH202: Public Health in 鶹ý, and PH203: Introduction to Global Public Health. Kauaʻi CC students who complete the program get a head start on a four-year degree and strengthen a seamless UH System pipeline.

The program is also offered to students at Waimea High School and Kapaāa High School through early college partnerships, allowing them to earn college credits that count toward both Kauaʻi CC and UH ԴDz.

“It’s so awesome to see high school students grapple with college material and make those important connections to public health,” said Yuka Polovina, a DPHS faculty member who currently teaches PH201. “This certificate and partnership with Kauaʻi CC is a fantastic model for other community colleges across our state and other campuses to follow.”

This program is a wonderful showcase of the collaborative academic pathway across the university system…
—Tetine Sentell

KDHO staff serve as guest lecturers, covering topics such as epidemiology, public health emergency preparedness, public health communications and outbreak control.

“We love the opportunity for our staff to share real-world local examples and make the work of public health come alive for Kauaʻi CC students,” said Janet Berreman, KDHO officer. “We get to see their excitement as they learn about the field.”

By introducing students to the field earlier, the program aims to increase local capacity and cultivate a future public health workforce drawn from the communities it serves. The initiative also supports UH President Wendy Hensel’s efforts to strengthen connections across the UH System.

The certificate by DPHS faculty Denise Nelson-Hurwitz, Lisa Kehl and Michelle Tagorda-Kama, with Tammie Napoleon and others at Kauaʻi CC. Yvette Amshoff, a DPHS master’s of public health graduate, taught the first cohorts and helped develop the program.

“This program is a wonderful showcase of the collaborative academic pathway across the university system, including our KDHO partners and DOE as well,” said Tetine Sentell, public health professor and DPHS department chair. “We are working to build more pathways like this to support public health across our islands and beyond.”

A study co-led by researchers at the University of 鶹ý at ԴDz has found that exposure to per- and polyfluoroalkyl substances (PFAS)—commonly known as “forever chemicals”—may significantly increase the risk of metabolic dysfunction-associated steatotic liver disease (MASLD) in adolescents. MASLD affects about 10% of children and up to 40% of children with obesity and can increase long-term risk for type 2 diabetes, heart disease and liver cancer.

The findings were published in and is a collaboration with the .

PFAS are synthetic chemicals used in nonstick cookware, stain- and water-repellent fabrics, food packaging and some cleaning products. They persist in the environment and accumulate in the body over time. More than 99% of people in the U.S. have measurable PFAS in their blood, and at least one PFAS is present in roughly half of U.S. drinking water supplies.

“Adolescents are particularly more vulnerable to the health effects of PFAS as it is a critical period of development and growth,” said assistant professor Shiwen “Sherlock” Li of UH ԴDz’ Department of Public Health Sciences in the , who served as lead and corresponding author. “In addition to liver disease, PFAS exposure has been associated with a range of adverse health outcomes, including several types of cancer.” ()

Linking PFAS, genetics and lifestyle

The research examined 284 adolescents and young adults in Southern California who were already at higher metabolic risk because their parents had type 2 diabetes or were overweight. PFAS levels were measured through blood tests, and liver fat was assessed using MRI.

Adolescents are particularly more vulnerable to the health effects of PFAS as it is a critical period of development and growth.
—Shiwen Li

Higher blood levels of two common PFAS chemicals—perfluorooctanoic acid (PFOA) and perfluoroheptanoic acid (PFHpA)—were linked to a greater likelihood of MASLD. Adolescents with twice as much PFOA in their blood were nearly three times more likely to have MASLD. The risk was even higher for those with a genetic variant (PNPLA3 GG) known to influence liver fat. In young adults, smoking further amplified PFAS-related liver impacts.

MASLD can progress silently for years before causing serious health problems,” said Lida Chatzi, professor of population and public health sciences and pediatrics and director of the . “When liver fat starts accumulating in adolescence, it may set the stage for a lifetime of metabolic and liver health challenges. If we reduce PFAS exposure early, we may help prevent liver disease later.”

Li noted that this is the first study to examine PFAS and MASLD in children using gold-standard diagnostic criteria and to explore how genetic and lifestyle factors may interact with PFAS exposure.

Reducing exposure

Exposure to PFAS can vary by location. Li recommends checking local Consumer Confidence Reports to see whether a water provider tests for PFAS, and using a water filter if PFAS are detected. Avoiding products or packaging made with PFAS may also help reduce exposure. Given rising rates of MASLD in young people worldwide, the researchers call for continued investigation and policies that reduce PFAS use in consumer products.

Other study partners also included the University of California Irvine, West Virginia University, Johns Hopkins University and Children’s Hospital Los Angeles.

While life expectancy across the U.S. declined significantly during the COVID-19 pandemic, a new study led by researchers at the University of 鶹ý and the found that 鶹ý experienced a smaller decline compared to national trends.

Yan Yan Wu, Michael Phillips and Kathryn L. Braun from the UH åԴDz , along with Lance Ching and Claire Prieto from the , found that life expectancy in 鶹ý declined by 1.4 years, from 82.1 in 2019 to 80.7 in 2021. Nationwide, the decline over the same period was 2.4 years, from 78.8 to 76.4. Their findings were published in the .

“The smaller magnitude and delayed timing of 鶹ý’s decline may reflect the state’s geographic isolation and early implementation of public health interventions,” said Wu, the study’s lead author. “In 2022, life expectancy partially rebounded by 0.5 years in 鶹ý and by 0.9 years nationally, with 鶹ý remaining about four years higher than the U.S. average throughout the pandemic.”

鶹ý ranks among the top U.S. states for COVID-19 vaccination coverage. By May 2023, data reported by the U.S. Centers for Disease Control and Prevention (CDC) showed that more than 90% of residents received at least one dose and more than 80% were considered fully vaccinated with the primary COVID-19 vaccine series,” said Ching, epidemiologist with the DOH Chronic Disease Prevention & Health Promotion Division. “These high vaccination levels—reached over the course of the pandemic—helped delay the peak of COVID-19 mortality in 鶹ý by approximately six months compared to the national average and contributed to the state’s distinction of having the lowest age-adjusted COVID-19 death rate in the country.”

Key Findings

  • Life expectancy in 鶹ý remained stable from 2018 to 2020 (82.3, 82.1, and 82.0 years, respectively).
  • A decline occurred in 2021 to 80.7 years, followed by a partial rebound to 81.2 years in 2022.
  • Among males, life expectancy fell from 79.2 years in 2018 to 77.5 years in 2021, then rose to 78.2 years in 2022.
  • Among females, life expectancy fell from 85.4 years in 2018 to 84.0 years in 2021, rebounding to 84.4 years in 2022.
  • The gap between female and male life expectancy widened to 6.5 years in 2021 before narrowing to 6.2 years in 2022—the same as in 2019.
  • Despite these fluctuations, 鶹ý‘s overall decline in life expectancy remained less severe than the U.S. average throughout the pandemic.

Policy Implications

The researchers note that 鶹ý‘s better outcomes underscore the effectiveness of early public health interventions, strong community engagement, and high vaccine uptake. They recommend that future policies build on these strengths by investing in rapid-response infrastructure and maintaining high vaccination coverage to better protect vulnerable communities during future disease outbreaks.
