How Anthropology and Epidemiology Are Revolutionizing Health Research Together
Explore the ResearchImagine an ambulance waiting at the top of a cliff, ready to help when people fall off. This metaphor describes how modern medicine often treats diseases after they appear rather than preventing them.
But what if we could understand why people are falling in the first place? What if we could identify the subtle environmental, social, and biological factors that push people toward the edge? This is precisely what bioethnographic collaboration aims to achieve—by combining the rich, contextual insights of anthropology with the precise measurements of epidemiology, researchers are creating better numbers that truly capture the complex realities of health and inequality in our world 1 3 .
In our data-driven era, numbers wield immense power—they shape policy decisions, determine funding allocations, and influence public health interventions. Yet, when these numbers fail to account for the messy realities of human life, they can lead to ineffective or even harmful solutions.
Enter bioethnography, an innovative approach that bridges the gap between qualitative lived experience and quantitative biological data. This article explores how this interdisciplinary collaboration is transforming health research, particularly in challenging environments like Mexico City, where social inequality creates dramatic health disparities 3 7 .
Bioethnography represents a methodological fusion that combines ethnographic observation with biochemical sampling to understand environment-body interactions as relational and situated processes. Unlike traditional mixed-methods approaches that often keep qualitative and quantitative data separate, bioethnography seeks to implode the boundaries between them from the very beginning of the research process 2 7 .
The approach begins with what might seem like excessive vagueness to scientists accustomed to hypothesis-driven research: anthropologists immerse themselves in communities, spending months or even years observing daily life without a predetermined research agenda. This open-ended approach allows patterns to emerge that might otherwise remain invisible to researchers who come with pre-formed categories and questions. Only after this period of ethnographic immersion does the team develop specific hypotheses to test using epidemiological methods 7 .
Bring together anthropologists and epidemiologists in the same research team, and you might expect some creative tension—and that's exactly what happens in bioethnographic collaborations. These interdisciplinary endeavors face significant challenges, as researchers from different fields often speak different academic languages, operate on different timelines, and approach problems with different epistemological assumptions 2 .
Seek epistemological clarity and fixed structures to move forward efficiently
Question fundamental paradigms and pose alternative questions that can slow the process
The key to overcoming these challenges lies in what team members call "mediators"—researchers who possess enough training in both qualitative and quantitative methods to translate between disciplines. These mediators (often graduate students or project managers) help bridge communication gaps by identifying misunderstandings, summarizing conversations, and pulling together readings that span both sets of disciplines. Rather than squashing conflicts, mediators harness the productive friction that emerges from disciplinary differences, transforming it into generative insights that move the research forward 2 .
One of the most illuminating examples of bioethnography in action comes from a sleep study conducted with adolescents in Mexico City. The research began when epidemiologists designed a survey to examine sleep patterns among teenagers in a long-term birth cohort study. Their survey included questions about technology use before bedtime, sleep duration, and sleep quality—based largely on assumptions drawn from research conducted in wealthy countries 7 .
When anthropologists who had spent years living with families in working-class neighborhoods of Mexico City reviewed the survey, they noticed a problem: the epidemiologists assumed that teenagers had their own bedrooms or shared with just one sibling. Through ethnographic observation, the anthropologists knew that bedroom sharing was far more common—with up to eight family members sharing a single sleeping space.
| Sleep Arrangement | Percentage of Participants | Reported Sleep Quality | Mental/Emotional Sleep Disturbances |
|---|---|---|---|
| Sleep alone | 23% | Fair to good | Higher reported disturbances |
| Share with 1-2 people | 42% | Good | Moderate disturbances |
| Share with 3+ people | 35% | Fair to good | Lower reported disturbances |
Researchers lived in participants' neighborhoods, spending 3-6 hours daily with families, documenting daily routines through field notes, photographs, and recordings 7 .
Ethnographic data was systematically analyzed to identify patterns related to sleep environments and practices 7 .
Researchers designed a sleep survey that included questions based on ethnographic insights, such as those about bedroom sharing 7 .
The survey was administered to 2,595 adolescents, and accelerometer data was collected from a subset to objectively measure sleep patterns 6 7 .
Both qualitative and quantitative data were analyzed together to understand the complex ecology of sleep 7 .
Another compelling example of bioethnography in action comes from research on water scarcity in Mexico City. While intermittent water supply is known to be a problem in many global South cities, its health impacts remained poorly understood until researchers combined ethnographic and epidemiological methods 4 .
Through open-ended interviews and ethnographic observations in 59 households, complemented by a large survey of 2,595 individuals, the research team discovered that most residents reported satisfaction with the quantity of water they received—but only because they invested significant financial resources and labor to adapt to scarcity. Households employed various strategies: storing water in large tanks, reusing water for multiple purposes, and conserving through changed habits 5 .
| Adaptation Strategy | Financial Cost | Time/Labor Cost | Health Implications |
|---|---|---|---|
| Water storage tanks | High initial investment | Moderate maintenance | Water quality degradation |
| Purchased bottled water | Ongoing expense | Low | Better drinking water quality |
| Water reuse practices | Low | High time investment | Potential contamination risk |
| Conservation behaviors | None | Behavioral adjustment | Reduced water availability |
These adaptations came at a cost—both monetary (expenses for storage tanks, pumps, and alternative water sources) and non-monetary (time-intensive labor spent managing water and noticeable deterioration in drinking water quality). Crucially, these burdens fell disproportionately on marginalized households, exacerbating existing inequalities 5 .
Conducting bioethnographic research requires both traditional anthropological tools and epidemiological instruments. The "Research Reagent Solutions"—essential components for this interdisciplinary work—include both conceptual frameworks and physical materials 7 .
| Research Reagent | Function | Role in Bioethnography |
|---|---|---|
| Ethnographic field notes | Records observations of daily life | Provides contextual insights to inform biological sampling |
| Biological sample collection kits | Collects biomarkers | Tests hypotheses generated from ethnographic data |
| Coding frameworks | Analyzes qualitative data | Identifies patterns for quantitative testing |
| Survey modules | Measures prevalence | Operationalizes ethnographic insights into quantifiable data |
| Statistical software | Analyzes numerical data | Integrates quantitative results with qualitative understanding |
Detailed observations documenting daily life, behaviors, and environments—the foundational qualitative data.
Materials for collecting and preserving biological samples (blood, urine, hair, toenails) for laboratory analysis.
Programs for analyzing quantitative data and integrating it with qualitative findings.
The potential applications of bioethnography extend far beyond the projects in Mexico City that have pioneered the approach. As researchers face increasingly complex global health challenges—from climate change to pandemics to rising inequality—methods that can capture the multifaceted nature of these problems become ever more essential 7 .
Bioethnography offers a promising approach for Developmental Origins of Health and Disease research, which has often been criticized for focusing too narrowly on individual behaviors rather than larger political-economic processes that shape health outcomes.
By revealing how social inequalities become embodied as biological disparities, bioethnography provides insights that can inform more effective and just public health interventions.
As bioethnography evolves, its practitioners emphasize that the goal is not to replace quantitative methods with qualitative ones, but to create a genuinely integrated approach that produces better numbers—numbers that are truly tethered to the complex relationships that shape health and inequality in our world 3 .
Bioethnographic collaboration represents more than just a methodological innovation—it offers a fundamentally different way of understanding health and disease. By imploding the boundaries between biological and social data, between quantitative and qualitative methods, and between different disciplinary perspectives, this approach generates insights that would be impossible within traditional research paradigms 1 7 .
The examples from Mexico City illustrate how this collaboration works in practice: anthropologists and epidemiologists working together to reveal how sleeping arrangements affect adolescent mental health, or how water scarcity becomes embodied as health disparities. In each case, the combination of ethnographic richness and epidemiological rigor produces more nuanced and more accurate knowledge about the world 7 .
As we face increasingly complex global health challenges, we need research methods that can equally capture complexity. Bioethnography offers a promising path forward—one that might help us not just to build better ambulances, but to prevent people from falling off the cliff in the first place.
