Cancer Stigma, Contraceptives, Covid-19: 2022 Global Health Research Showcase

Last Monday, Oct. 17, Duke University students who had conducted global health research had the opportunity to present their work. From North Carolina to Sub-Saharan Africa, the 2022 Global Health Research Showcase featured works that tackle some of the world’s most pressing health issues. Over 40 undergraduate, Masters, and PhD student projects examined a broad range of issues, determinants, and phenomena in countries from almost every continent. Here’s a few project highlights, in case you missed it:

Maeve Salm, pursuing her Master of Science in Global Health, went to Tanzania to study contraceptive use. Tanzania’s youth are highly impacted by teen pregnancy, and Salm wanted to understand desires for contraceptive use among adolescents affected by HIV. She learned that, much like in the U.S., stigma influences access to sexual healthcare for adolescents. This qualitative study aimed to support young people in achieving their desired health outcomes and reducing HIV transmission by examining barriers and facilitators to family planning. Findings indicate that youth agency in reproductive health is of utmost importance.

Wondering about the Covid-19 response in other countries? Master of Science in Global Health Candidate Stephanie Stan explored the barriers and enablers to the pandemic response in Peru. Per capita, Peru experienced the highest mortality rate form the disease compared to any other country. Due to several challenging factors, they were slow to receive COVID-19 vaccines. However, they implemented highly successful vaccination campaigns once vaccines were obtained. What can be learned from Peru’s pandemic response? Prolonged and proactive collaborations between sectors (healthcare, academics, and government) enable swift public health responses in a crisis. It’s important to have elected officials who are empowered to make decisions promoting science.

“Definitely meeting all the incredible people that I interviewed and learning about their work and involvement in Peru’s pandemic response. Learning about what happens moving forward from their point of view.”

Winning the first-place Graduate Student Research Award, Judith Mwobobia’s project examined the stigma of cancer in sub-Saharan Africa. Stigma is a huge barrier to receiving treatment, which is a problem considering that 70% of global cancer deaths originate from Africa. Perceptions of financial stress, misconceptions about cancer, and fear of death were common attitudes driving cancer stigma. Proposed interventions included education and policy recommendations for low-resourced communities. Mwobobia is pursuing her Master of Science in Global Health. Clearly a supportive group, her classmates erupted in cheers when the award was announced.

Is it Time to Decolonize Global Health Data?

In the digital age, we are well-acquainted with “data,” a crouton-esque word tossed into conversations, ingrained in the morning rush like half-caf cappuccinos and spreadsheets. Conceptually, data feels benign, necessary, and totally absorbed into the zeitgeist of the 21st century (alongside Survivor, smartphones, and Bitcoin). Data conjures up the census; white-coat scientists and their clinical trials; suits and ties; NGO board meetings; pearled strings of binary code; bar graphs, pie charts, scatter plots, pictographs, endless excel rows and columns, and more rows and more columns.

However, within the conversation of global health, researchers and laymen alike would more often than not describe data collection, use, and sharing as critical for resource mobilization, disease monitoring, surveillance prevention, treatment, etc. (Look at measles eradication! Polio! Malaria! Line graphs A, B, and C!)

Thanks to the internet, extracting health data is also faster, easier, and more widespread than ever . We have grown increasingly concerned, and rightfully so, about data ownership and data sovereignty.

Who is privy to data? Who can possess it? Can you possess it? As you can see, the conversation quickly becomes convoluted, philosophical even.

Dr. Wendy Prudhomme O’Meara is an associate professor at Duke University Medical School in the Division of Infectious Diseases, visiting professor at Moi University, and the Co-Field Director of Research for AMPATH. Her research focuses on malaria. 

Dr. Wendy Prudhomme O’Meara, moderator of the Data as a Commodity seminar on Sept. 29 and associate professor at Duke University Medical School in the Division of Infectious Diseases, discussed bioethical complexities of data creation and ownership within global health partnerships.

“We can see that activities—where data is being collected in one place, removed from the context, and value being extracted from it for personal or financial benefit — has very strong parallels to the kind of resource extraction and exploitation that characterized colonization,” she said in her introductory remarks.

Data, like other raw materials (i.e. coffee, sugar, tobacco, etc.), can be extracted, often disproportionately, from lower-middle income countries (LMICs) at the expense of the local populations. This reinforces unequal power dynamics and harkens to the tenets of colonialism and imperialism.

This observation is exemplified by panelist Thiago Hernandes Rocha’s research which focuses on public policy evaluation and data mining. He acknowledges that global health research, in general, should prioritize the health improvements of the studied community rather than publications or grant funding. This may seem somewhat obvious to you; however, though academic competition often fosters nuances in the field, it also contributes to the commercialization of global health. Don’t be shy, everyone point your finger at Big Pharma!

Though Dr. Rocha’s data mining technique refers to “pattern-searching” and analysis of dense data sets, I find “mining” to be an apt analogy for the exploitative potential of data extraction and research partnerships between higher income countries and LMICs.

Dr. Thiago Hernandes Rocha joins the discussion via Zoom. He is an advisor on health data analysis for the Pan American Health Organization.

Consider the British diamond industry in Cape Colony, South Africa, and the parallels between past colonial mineral extraction and current global health data extraction. Imagine taking a pickaxe to the earth.

Now consider the environmental ramifications of mining, and who they disproportionately affect. Consider the lingering social and economic inequalities. Of course, data is not a mine of diamonds (as your Hay Day farm might suggest) nor is it ivory or rubber or timber. It’s less tangible (you can’t necessarily hold it or physically possess it) and, therefore, its extraction also feels less tangible, even though this process can have very concrete consequences.

Data as a power dynamic is a rather recent characterization in academic discourse. Researchers and companies alike have pushed the “open data” movement to increase data availability to all people for all uses. You can see how, in a utopian society, this would be fantastic. Think of the transparency! I’m sure you can also see how, in our non-utopian society, this can be exploited.

Dr. Bethany Hedt-Gauthier, a Harvard University biostatistician and seminar speaker, described herself as “pro ‘open data’ … in a world without power dynamics” — an amendment critical to understanding research as a commodity itself.

She justified her stance by referencing the systematic review of authorship in collaborative health research in Africa that she conducted in collaboration with others in the field. They found that even when sub-Saharan African populations were the main sites of study, when partnered with high-income, elite institutions (like Duke or Harvard), the African authors were significantly less likely to be first or senior authors despite the comparable number of academics on both sides of the partnership. To what can we attribute this discrepancy?

Dr. Bethany Hedt-Gauthier is a biostatistician in health systems research that focuses on the optimization of care and health outcomes in sub-Saharan Africa.

Dr. Hedt-Gauthier describes forms of capital that contribute to this issue, from cultural capital (i.e. credentials) to symbolic capital (i.e. legitimacy) to financial capital; however, she poses colonialism (and its continuity in socioeconomic and political power dynamics today) as the root of this incongruity from which the aforementioned forms of capital bud and flower like poisonous oleander. In recent years, institutions, including Duke, have increased efforts to “decolonize” global health to achieve greater equity, equal participation, and better health outcomes overall. 

Dr. Hedt-Gauthier briefly chronicled some of her own research in Rwanda at the start of the COVID-19 pandemic. Within her research partnerships, she recollected slowing down, thoughtfully engaging in two-way dialogue, and posing questions like the following: “Who is involved [in the partnership]?” “Are all parties equally represented in paper authorship?” “If not, how can we share resources to ensure this?” “How can we assure that the people involved in the generation of data are also involved in the interpretation of its results?” “Who has access to data?” “What does co-authorship look like?”

Investing time and energy into multi-country databases, funding collaborative research infrastructures, removing barriers within academia, and training researchers are just some of the methods proposed by the speakers to facilitate equitable partnerships, data sharing and use, and continued global health decolonization.

Dr. Osondu Ogbuoji is an Assistant Research Professor at Duke Global Health Institute (DGHI) and Deputy Director at the Center for Policy Impact in Global Health at DGHI.

Dr. Osondu Ogbuoji, the final panelist, puts it best: “… We should ensure that the people in the room having the discussion about what values the data has should be as diverse as possible and ideally should have all the stakeholders. In our own research, sometimes we think we have an idea of what data to collect, but then we talk to the country partners and they have a totally different idea.”

Though the question of data ownership may feel lofty or intangible, though data legality is confusing, though you may feel yourself adrift in the debate of commodity and capital, the speakers have thrown you a buoy, grab on, and understand that generally:

It is necessary to engage with “data” in a communicative and critical manner; it is necessary to build research partnerships that are synergistic and reciprocal; and, finally, it is necessary to approach global health via these partnerships to advance the field towards greater equity.
