Preface to the Third Edition
The field of public health is typically regarded as a positivistic pursuit. Our understanding of and response to disease and injury at the population level are undoubtedly guided by the scientific method. Public health policies, however, are shaped not only by science but also by ethical values, legal norms, and political oversight. Public Health Law and Ethics: A Reader probes this complex interplay through a careful selection of excerpts from judicial opinions, statutes, regulations, government reports, and scholarly articles.
Now in its third edition, this reader provides a resource for scholars, students, practitioners, teachers, and interested members of the public. Each chapter illuminates key issues in public health law and ethics and frames relevant questions. We introduce the selected excerpts, provide commentary on their significance, and suggest additional resources for readers interested in further exploration.
The reader can also be used as a companion to the third edition of Public Health Law: Power, Duty, Restraint, published in 2016. The treatise provides a careful analysis of the major tensions in public health law theory and practice, while this reader offers cases and materials selected to inspire informed discussion and debate.
This reader, like the companion text, is organized into four major parts:
Part One. Conceptual Foundations of Public Health Law and Ethics
Part Two. Legal Foundations of Public Health
Part Three. Modes of Legal Intervention
Part Four. Public Health Law in Context
Part One covers the conceptual foundations of public health law and ethics in two chapters—one developing a theory and definition of the field and the other offering a systematic scientific and ethical evaluation of public health regulation.
Part Two comprises three chapters that cover the legal foundations of public health powers and practices at the federal, state, and local level: constitutional law, administrative law, and local government law. These chapters contain considerable discussion of legal doctrine that may, at once, be insufficiently detailed for public health practitioners and students new to the study of law and overly pedantic for lawyers and law students who are familiar with much of what is presented. Despite the unavoidable difficulties of addressing multiple audiences, we felt it important to develop a common understanding of the legal basis for the exercise of public health powers and the limits on those powers.
Part Three, consisting of three chapters, explores the modes of legal intervention identified in the book’s opening chapter: direct regulation and deregulation; indirect regulation through tort liability; and indirect regulation via taxation and spending. These chapters examine the regulatory toolkit in detail, including through case studies. We address the advantages and detriments of various approaches, including in terms of economic efficiency, political accountability, and vulnerability to legal challenge.
Part Four, made up of six chapters, examines legal issues and ethical dilemmas within the context of several major silos of public health practice. We explore key concepts and trends in public health surveillance and research, infectious diseases, emergency preparedness and response, and prevention of injuries and violence. We run the risk of providing too cursory a review for lawyers new to the study of public health while reviewing concepts too elementary for experienced public health practitioners and students. Nonetheless, this approach illuminates the paradoxes of public health law (e.g., the fact that public health regulation is often challenged or neglected because the benefits cannot be traced to any particular individual while personal and economic burdens are more evident). We conclude with reflections on the future of public health law, with particular attention to the devastating impact of health disparities on our society and the challenges of balancing transparency and democratic accountability with the need for expeditious and far-reaching action to ensure a greater measure of justice for disadvantaged groups.
We have used a modified version of The Chicago Manual of Style (sixteenth edition) for the bibliography and endnotes and The Bluebook: A Uniform System of Citation (twentieth edition) for judicial cases, statutes, and regulations.
We have heavily edited many of the excerpts collected in the reader to highlight the most essential issues in public health law and ethics. In a few cases, we have condensed edited paragraphs to maintain the flow of analysis. In the case of judicial opinions, we have often omitted internal quotation marks and citations to prior case law.
ACKNOWLEDGMENTS
We are indebted to many people for their vital contributions to this reader.
We had exceptional editorial and research assistance at Georgetown Law and American University Washington College of Law. In particular, Dan Hougendobler, Anna Roberts, and Katharina Eva Ó Cathaoir, fellows of Georgetown’s O’Neill Institute for National and Global Health Law, spent endless hours meticulously editing text, footnotes, figures, and tables; obtaining permissions; and coordinating the efforts of student research assistants. The current edition also owes a great deal to the invaluable work of Ben Berkman on the second edition. Among the students participating on the research team for this edition were Michael Chandeck, Rebecca Dittrich, Maya Frazier, Mehgan Gallagher, Payal Mehta, and Lucas Novaes.
Our collaborations and scholarly exchanges with colleagues from health law and related fields have intimately informed our work on this reader, including Marice Ashe, Mike Bader, Leo Beletsky, Micah Berman, Doug Blanke, Kim Blankenship, Kelly Brownell, Scott Burris, Brietta Clark, Dick Daynard, Bob Dinerstein, Sean Flynn, Lance Gable, Lewis Grossman, Anand Grover, Sam Halabi, Christina Ho, James Hodge, Nicole Huberfeld, Peter Jacobson, Renée Landers, Heather McCabe, Manel Kappagoda, Roger Magnusson, Gwendolyn Majette, Jessica Mantel, Wendy Mariner, Benjamin Mason Meier, Gene Matthews, Kevin Outterson, Wendy Parmet, Anne Pearson, Matt Pierce, Jennifer Pomeranz, Jennifer Puhl, Seema Mohaptra Reddy, Jessica Roberts, Carol Runyan, Lainey Rutkow, Bill Sage, Jason Sapsin, Liz Sepper, Steve Teret, Stacey Tovino, Jon Vernick, and Sidney Watson.

Conceptual Foundations of Public Health Law and Ethics
CHAPTER ONE
Law and the Public’s Health
Mapping the Terrain
PHOTO 1.1. A doctor gives a typhoid inoculation at a rural school in Texas, 1943. Typhoid fever, a bacterial infection with a high fatality rate, was once common in the United States. Incidence decreased rapidly in the 1940s due to improvements in sanitation (especially chlorination of drinking water), development of effective antibiotic treatments, and vaccination. Today, there are only about 400 cases of typhoid in the United States each year, the vast majority among travelers returning from regions where infection remains endemic. Routine vaccination of schoolchildren is no longer recommended, but voluntary vaccination of travelers is crucial to protect the public’s health, particularly in light of the growing prevalence of multidrug-resistant strains of typhoid.

The theory and practice of public health raise questions that are not resolved solely through scientific inquiry; rather, law and ethics guide the public health enterprise alongside epidemiology and biostatistics. Despite the close interplay among public health science, law, and ethics, each has its own methods and terminology. Until recently, cross-fertilization was rare. Most scholars and practitioners in the fields of law and ethics who have engaged in sustained examination of issues in health have focused principally on the financing and delivery of medical care and the conduct of medical research. The distinct perspectives and practices of public health have received far less attention. Fortunately, a growing number of practitioners, scholars, and organizations are developing public health law and public health ethics into fully fledged fields that stand alongside the related fields of health care law and bioethics.
Before applying ethics or law to problems in public health, it is important first to understand what we mean by public health. In this chapter, we highlight the prevention orientation, population perspective, and commitment to social justice that distinguish public health from medicine. We describe evolving models of public health science and practice, culminating in the social-ecological model. We conclude by surveying an ongoing debate over the legitimate scope of public health law, triggered by increased attention to noncommunicable diseases (e.g., cancer, heart disease, diabetes), injuries (e.g., motor vehicle, firearm, and overdose fatalities), and the social, economic, and environmental determinants of health in recent decades.
THE PREVENTION ORIENTATION AND THE POPULATION PERSPECTIVE
Public health inquiries and interventions are aimed at the prevention of injury, disease, and premature death at the population level. The Institute of Medicine (IOM) (1988, 19) in its landmark report The Future of Public Health proposed one of the most influential contemporary definitions of public health: Public health is what we, as a society, do collectively to assure the conditions for people to be healthy.
The IOM’s emphasis on cooperative and mutually shared obligation (we, as a society
) reinforces that collective entities (e.g., governments and communities) take responsibility for healthy populations. The definition also adopts a broad focus on social, environmental, cultural, and economic factors (the conditions for people to be healthy
) that shape health-related behaviors and outcomes.
In the excerpt that follows, Rose offers a comparison between how medicine and public health approach questions of causation and methods for prevention. Why did this patient get this disease at this time?
is a common question in medicine, underscoring a physician’s principle concern for individuals. By contrast, those interested in public health seek knowledge about why ill health occurs in the population and how it can be prevented through structural, rather than individual, interventions.
SICK INDIVIDUALS AND SICK POPULATIONS¹
Geoffrey Rose
THE DETERMINANTS OF INDIVIDUAL CASES
In teaching epidemiology to medical students, I have often encouraged them to consider a question which I first heard enunciated by Roy Acheson: "Why did this patient get this disease at this time?" It is an excellent starting point, because students and doctors feel a natural concern for the problems of the individual. Indeed, the central ethos of medicine is seen as an acceptance of responsibility for sick individuals.
It is an integral part of good doctoring to ask not only, What is the diagnosis, and what is the treatment?
but also, Why did this happen, and could it have been prevented?
Such thinking shapes the approach to nearly all clinical and laboratory research into the causes and mechanisms of illness. Hypertension research, for example, is almost wholly preoccupied with the characteristics which distinguish individuals at the hypertensive and normotensive ends of the blood pressure distribution. Research into diabetes looks for genetic, nutritional and metabolic reasons to explain why some people get diabetes and others do not. The constant aim in such work is to answer Acheson’s question, Why did this patient get this disease at this time?
The same concern has continued to shape the thinking of all of us who came to epidemiology from a background in clinical practice. The whole basis of the case-control method [(a retrospective study design in which researchers compare the history of individuals who have a condition [cases
] to the history of individuals who do not [controls
])] is to discover how sick and healthy individuals differ. Equally the basis of many cohort studies [(prospective studies in which researchers follow a group of similarly situated individuals over time to see which of them develops the condition of interest)] is the search for risk factors,
which identify certain individuals as being more susceptible to disease; and from this we proceed to test whether these risk factors are also causes, capable of explaining why some individuals get sick while others remain healthy, and applicable as a guide to prevention. . . .
Unfortunately this approach to the search for causes, and the measuring of their potency, has to assume a heterogeneity of exposure within the study population. If everyone smoked 20 cigarettes a day, then clinical, case-control and cohort studies alike would lead us to conclude that lung cancer was a genetic disease; and in one sense that would be true, since if everyone is exposed to the necessary agent, then the distribution of cases is wholly determined by individual susceptibility. Within Scotland and other mountainous parts there is no discernible relation between local cardiovascular death rates and the softness of the public water supply. The reason is apparent if one extends the enquiry to the whole of the UK. In Scotland, everyone’s water is soft [meaning that it contains low levels of calcium and magnesium]; and the possibly adverse effect becomes recognizable only when study is extended to other regions which have a much wider range of exposure. . . . Even more clearly, a case-control study of this question within Scotland would have been futile. Everyone is exposed, and other factors operate to determine the varying risk. Epidemiology is often defined in terms of study of the determinants of the distribution of the disease; but we should not forget that the more widespread is a particular cause, the less it explains the distribution of cases. The hardest cause to identify is the one that is universally present, for then it has no influence on the distribution of disease.
THE DETERMINANTS OF POPULATION INCIDENCE RATE
I find it increasingly helpful to distinguish two kinds of etiological question. The first seeks the causes of cases, and the second seeks the causes of incidence. Why do some individuals have hypertension?
is a quite different question from Why do some populations have much hypertension, whilst in others it is rare?
The questions require different kinds of study, and they have different answers. . . .
To find the determinants of prevalence and incidence rates, we need to study characteristics of populations, not characteristics of individuals. . . . Within populations it has proved almost impossible to demonstrate any relation between an individual’s diet and his serum cholesterol level; and the same applies to the relation of individual diet to blood pressure and to overweight. But at the level of populations it is a different story: it has proved easy to show strong associations between population mean values for saturated fat intake versus serum cholesterol level and coronary heart disease incidence, sodium intake versus blood pressure, or energy intake versus overweight. The determinants of incidence are not necessarily the same as the causes of cases. . . .
PREVENTION
These two approaches to etiology—the individual and the population-based—have their counterparts in prevention. In the first, preventive strategy seeks to identify high-risk susceptible individuals and to offer them some individual protection. In contrast, the population strategy
seeks to control the determinants of incidence in the population as a whole.
The High-Risk
Strategy
This is the traditional and natural medical approach to prevention. If a doctor accepts that he is responsible for an individual who is sick today, then it is a short step to accept responsibility also for the individual who may well be sick tomorrow. Thus screening is used to detect certain individuals who hitherto thought they were well but who must now understand that they are in effect patients. . . .
What the high-risk
strategy seeks to achieve is something like a truncation of the risk distribution. This general concept applies to all special preventive action in high-risk individuals—in at-risk pregnancies, in small babies, or in any other particularly susceptible group. It is a strategy with some clear and important advantages. . . .
The high-risk
approach offers a more cost-effective use of limited resources. . . . [I]t is more effective to concentrate limited medical services and time where the need—and therefore also the benefit—is likely to be greatest. . . . If intervention must carry some adverse effects or costs, and if the risk and cost are much the same for everybody, then the ratio of the costs to the benefits will be more favorable where the benefits are larger.
Unfortunately the high-risk
strategy of prevention also has some serious disadvantages and limitations. . . . [I]t is palliative and temporary, not radical. It does not seek to alter the underlying causes of the disease but to identify individuals who are particularly susceptible to those causes. Presumably in every generation there will be such susceptibles; and if prevention and control efforts were confined to these high-risk individuals, then that approach would need to be sustained year after year and generation after generation. It does not deal with the root of the problem, but seeks to protect those who are vulnerable to it; and they will always be around.
The potential for this approach is limited—sometimes more than we could have expected—both for the individual and for the population. There are two reasons for this. The first is that our power to predict future disease is usually very weak. Most individuals with risk factors will remain well, at least for some years; contrariwise, unexpected illness may happen to someone who has just received an all clear
report from a screening examination. One of the limitations of the relative risk statistic is that it gives no idea of the absolute level of danger. . . .
This point came home to me only recently. I have long congratulated myself on my low levels of coronary risk factors, and I joked to my friends that if I were to die suddenly, I should be very surprised. I even speculated on what other disease—perhaps colon cancer—would be the commonest cause of death for a man in the lowest group of cardiovascular risk. The painful truth is that for such an individual in a Western population the commonest cause of death—by far—is coronary heart disease! Everyone, in fact, is a high-risk individual for this uniquely mass disease.
There is another, related reason why the predictive basis of the high-risk
strategy of prevention is weak. It is well illustrated by . . . the [correlation of] occurrence of Down’s syndrome births to maternal age. Mothers under 30 years are individually at minimal risk; but because they are so numerous, they generate half the cases. High-risk individuals aged 40 and above generate only 13% of the cases. The lesson from this example is that a large number of people at a small risk may give rise to more cases of disease than the small number who are at a high risk. This situation seems to be common, and it limits the utility of the high-risk
approach to prevention.
A further disadvantage of the high-risk
strategy is that it is behaviorally inappropriate. Eating, smoking, exercise and all our other life-style characteristics are constrained by social norms. If we try to eat differently from our friends it will not only be inconvenient, but we risk being regarded as cranks or hypochondriacs. If a man’s work environment encourages heavy drinking, then advice that he is damaging his liver is unlikely to have any effect. No one who has attempted any sort of health education effort in individuals needs to be told that it is difficult for such people to step out of line with their peers. This is what the high-risk
preventive strategy requires them to do.
The Population Strategy
This is the attempt to control the determinants of incidence, to lower the mean level of risk factors, to shift the whole distribution of exposure in a favorable direction. In its traditional public health
form it has involved mass environmental control methods; in its modern form it is attempting (less successfully) to alter some of society’s norms of behavior.
The advantages are powerful. The first is that it is radical. It attempts to remove the underlying causes that make the disease common. It has a large potential—often larger than one would have expected—for the population as a whole. . . .
The approach is behaviorally appropriate. If non-smoking eventually becomes normal,
then it will be much less necessary to keep on persuading individuals. Once a social norm of behavior has become accepted and (as in the case of diet) once the supply industries have adapted themselves to the new pattern, then the maintenance of that situation no longer requires effort from individuals. The health education phase aimed at changing individuals is, we hope, a temporary necessity, pending changes in the norms of what is socially acceptable.
Unfortunately the population strategy of prevention has also some weighty drawbacks. It offers only a small benefit to each individual, since most of them were going to be all right anyway, at least for many years. This leads to the Prevention Paradox (Rose 1981): A preventive measure which brings much benefit to the population offers little to each participating individual.
This has been the history of public health—of immunization, the wearing of seat belts and now the attempt to change various life-style characteristics. Of enormous potential importance to the population as a whole, these measures offer very little—particularly in the short term—to each individual; and thus there is poor motivation of the subject. We should not be surprised that health education tends to be relatively ineffective for individuals and in the short term. Mostly people act for substantial and immediate rewards, and the medical motivation for health education is inherently weak. Their health next year is not likely to be much better if they accept our advice or if they reject it. Much more powerful as motivators for health education are the social rewards of enhanced self-esteem and social approval. . . .
CONCLUSIONS
The high-risk
strategy of prevention is an interim expedient, needed in order to protect susceptible individuals, but only for so long as the underlying causes of incidence remain unknown or uncontrollable; if causes can be removed, susceptibility ceases to matter.
Realistically, many diseases will long continue to call for both approaches, and fortunately competition between them is usually unnecessary. Nevertheless, the priority of concern should always be the discovery and control of the causes of incidence.

Michael J. McGinnis and William H. Foege noted in 1993 that the biomedical model of record keeping and the societal need to explain a cause of death in terms of a discrete medical condition can distract the public from the root causes of disease. Medical explanations of death, often in the form of code numbers from the International Classification of Disease (ICD) on death certificates, point to discrete pathophysiological conditions or events, such as heart attack, stroke, cancer, diabetes, pneumonia, or suicide. In contrast, from the population perspective, McGinnis and Foege focused on what they labeled the actual causes of death
: tobacco, diet and activity patterns, alcohol, firearms, sexual behavior, motor vehicles, and illicit drug use. Ten years later, Ali H. Mokdad and his coauthors (2004) updated the statistics marshaled by McGinnis and Foege, noting trends in the leading modifiable causes of death over time. Sandro Galea and his coauthors (2011) built on this framework by assessing the impact of individual-level factors (e.g., educational attainment, household income, health insurance status, employment status, job stress, household conditions, level of social support, experience of racism or discrimination, housing conditions, and early childhood stressors) as well as community-level factors (e.g., area-level poverty, income inequality, deteriorating built environment, racial segregation, crime and violence, social capital, and availability of open or green spaces). They attributed approximately 245,000 premature deaths in the United States each year to low education, 176,000 to racial segregation, 162,000 to low social support, 133,000 to individual-level poverty, 119,000 to income inequality, and 39,000 to area-level poverty (Galea et al. 2011, 1462). Similarly, Anne Case and Angus Deaton (2017) have found that increases in deaths of despair
(e.g., drug overdoses, suicides, and deaths due to alcohol-related liver disease) are attributable to a long-standing process of cumulative disadvantage for those with less than a college degree,
contributing to an overall increase in premature mortality among middle-aged non-Hispanic white people in recent years. Attributing deaths to economic despair, experiences of racism, early childhood stressors, and other social determinants of health may seem foreign to those accustomed to measuring mortality in terms of discrete medical causes such as cardiovascular disease or cancer. It is a powerful expression of the population perspective adopted by public health experts.
There are, of course, many things that individuals can do to protect their own health, particularly if they have the economic means to do so. They can purchase housing, clothing, food, and medical care. Each person can also behave in ways that promote health and safety by eating a balanced diet, being physically active, using safety equipment (e.g., seatbelts, motorcycle helmets, smoke detectors, and protective equipment at work), refraining from tobacco use and drug and alcohol abuse, using sunscreen, and getting recommended vaccinations and screening tests. But, as the work of Case, Deaton, Galea, Mokdad, McGinnis, Foege, and others shows, these individual behaviors are shaped by social determinants. Law itself acts as a social determinant of health, allocating resources, creating incentives and disincentives, and shaping the social environment, the information environment, and the built environment in which people make choices that affect their health.
Furthermore, there are some kinds of health protection that no individual, acting alone, can achieve fully. The classic example is community immunity. A vaccination may by highly effective—providing protection from a communicable disease to, for example, 95% of those who are immunized. Some individuals may be unable to get vaccinated because of medical conditions, such as leukemia, that make it medically inadvisable. Others may opt out of immunizations due to religious or philosophical objections. Others may get a vaccination, but have the misfortune of being among the 5% of those who are vaccinated but nonetheless are vulnerable to infection. Only community immunity (also known as herd immunity) can ensure eradication of an infectious disease by protecting everyone—the vaccinated as well as the unvaccinated—from infection (see chapter 10). Acting alone, individuals cannot achieve control of infectious disease, clean air and surface water, uncontaminated food and drinking water, safe roads and products, and community norms and social structures that support safer, healthier lifestyles.
Protecting public health also requires actions that no individual is fully incentivized to take, even if it were within one’s power to do so, because it is impossible to know which individuals will benefit. For example, policymakers know that reducing tobacco use saves lives. Statisticians can document how many fewer people are smoking today than were smoking in the 1960s before tobacco control measures were in place. Epidemiologists can measure the impact of cigarette taxes on smoking prevention. But it is impossible to point to any specific individual and say, this person’s life was saved because the cigarette tax was high enough to keep her from taking up smoking when she was fourteen.
Similarly, it is well known that exposure to lead-contaminated water and soil and deteriorating lead paint causes intellectual impairment and behavioral disorders. Health agencies can document how many children have blood lead levels that are unsafe. At the population level, epidemiologists may even be able to estimate the amount of intellectual impairment and behavioral disorder attributable to lead paint exposure. But it is exceedingly difficult to prove that any given individual would not be experiencing an intellectual impairment or behavioral disorder but for his exposure to lead paint.
Indeed, the collective action problem in public health is the often at the root of its politicization. This is the prevention paradox that Rose describes above. Measures that have the greatest potential for improving health at the population level (e.g., reduction of sodium content in restaurant food) offer little traceable benefit to any identifiable individual. Measures that heroically save identifiable lives (e.g., heart transplants) make no significant contribution to the population’s health. This tension between individual interests and collective needs can be seen in how success is quantified for health interventions. The answer to the question Was this patient’s health improved?
indicates success for the physician. For the public health professional, the key question is whether the disease and injury burden were reduced at the population level, with virtually no ability to tie names or faces to such an achievement. Although Rose acknowledges that medical interventions appear more heroic and are more likely to be welcomed by patients, he favors the broad and powerful impact of successful population-based campaigns.
Ongoing partisan disagreements over health care reform have focused the nation’s attention on access to heroic medical interventions. In town halls across the country, individuals describe their dire need for subsidized health insurance coverage as they battle cancer, congestive heart failure, and other serious conditions. At the same time, sweeping changes in how health care is financed have led policymakers to view prevention as a key cost-control strategy. The Affordable Care Act included several measures to increase access to preventive health care and promote community-level prevention. In the following excerpt, Harry J. Heiman and Samantha Artiga place these trends in context and highlight the crucial importance of the social determinants of health.
BEYOND HEALTH CARE: THE ROLE OF SOCIAL DETERMINANTS IN PROMOTING HEALTH AND HEALTH EQUITY²
Harry J. Heiman and Samantha Artiga
Efforts to improve health in the United States have traditionally looked to the health care system as the key driver of health and health outcomes. The Affordable Care Act (ACA) increased opportunities to improve health by expanding access to health coverage and supporting reforms to the health care delivery system. While increasing access to health care and transforming the health care delivery system are important, research demonstrates that improving population health and achieving health equity also will require broader approaches that address social, economic, and environmental factors that influence health. . . .
DETERMINANTS OF HEALTH
Many factors combine to affect the health of individuals and communities. Despite annual health care expenditures projected to exceed $3 trillion, health outcomes in the United States continue to fall behind other developed countries. Recent analysis shows that, although overall spending on social services and health care in the United States is comparable to other Western countries, the United States disproportionately spends less on social services and more on health care. Though health care is essential to health, research demonstrates that it is a relatively weak health determinant. Health behaviors, such as smoking and diet and exercise, are the most important determinants of premature death (figure [1.1]). Moreover, there is growing recognition that a broad range of social, economic, and environmental factors shape individuals’ opportunities and barriers to engage in healthy behaviors.

Social determinants have a significant impact on health outcomes. Social determinants of health are the structural determinants and conditions in which people are born, grow, live, work and age
(Marmot et al. 2008). They include factors like socioeconomic status, education, the physical environment, employment, and social support networks, as well as access to health care ([see table 1.1]). Based on a meta-analysis of nearly 50 studies, researchers found that social factors, including education, racial segregation, social supports, and poverty accounted for over a third of total deaths in the United States in a year. In the United States, the likelihood of premature death increases as income goes down. Similarly, lower education levels are directly correlated with lower income, higher likelihood of smoking, and shorter life expectancy. Children born to parents who have not completed high school are more likely to live in an environment that poses barriers to health. Their neighborhoods are more likely to be unsafe, have exposed garbage or litter, and have poor or dilapidated housing and vandalism. They also are less likely to have sidewalks, parks or playgrounds, recreation centers, or a library. In addition, poor members of racial and ethnic minority communities are more likely to live in neighborhoods with concentrated poverty than their poor White counterparts. There is also growing evidence demonstrating that stress negatively impacts health for children and adults across the lifespan. Recent research showing that where a child grows up impacts his or her future economic opportunities as an adult also suggests that the environment in which an individual lives may have multi-generational impacts.
TABLE 1.1 SOCIAL DETERMINANTS OF HEALTH
Addressing social determinants of health is important for achieving greater health equity. The presence of health disparities is well established in the United States. Longstanding research has consistently identified disparities experienced by racial and ethnic minority, low-income, and other vulnerable communities. [In its ten-year plan for improving the nation’s health, Healthy People 2020, t]he Department of Health and Human Services defines health disparities as differences in health outcomes that are closely linked with social, economic, and environmental disadvantage.
Healthy People 2020 goes on to state that health disparities adversely affect groups of people who have systematically experienced greater obstacles to health based on their racial or ethnic group; religion; socioeconomic status; gender; age; mental health; cognitive, sensory, or physical disability; sexual orientation or gender identity; geographic location; or other characteristics historically linked to discrimination or exclusion.
These definitions recognize that health disparities are rooted in the social, economic, and environmental context in which people live. Achieving health equity—defined by Healthy People 2020 as the highest level of health for all people—will require addressing these social and environmental determinants through both broad population-based approaches and targeted approaches focused on those communities experiencing the greatest disparities.
ADDRESSING SOCIAL DETERMINANTS OF HEALTH
Recently there has been increasing recognition of the importance of social determinants of health. A growing number of initiatives are emerging to address these broader determinants of health and develop integrated solutions within the context of the health care delivery system. . . .
Mapping and Place-Based Approaches
A number of initiatives are using geospatial analysis and community needs assessments to guide place-based approaches to address social and environmental factors impacting individual and community health. The importance of mapping and geospatial analysis for assessing and addressing health needs dates back to John Snow’s work in 1854 to identify the source of the London cholera epidemic. Today, the importance of the relationship between neighborhoods and health continues to be recognized, with zip code understood to be a stronger predictor of a person’s health than their genetic code. As described in the examples below, [a] number of initiatives in place today focus on neighborhoods with social, economic, and environmental barriers that lead to poor health outcomes and health disparities.
One example of these place-based approaches is an initiative in Camden, New Jersey, that focuses on high utilizers of hospital care. The population of Camden has a high poverty rate and historically poor access to care, with a high share of emergency department and hospital visits for preventable conditions that are treatable by a primary care provider. Individuals were having difficulty accessing primary care along with a number of behavioral, social, and medical issues. In response to these challenges, the Camden Coalition of Health Care Providers created a citywide care management system to help connect high utilizers of hospital emergency departments with primary care providers. The care management team includes providers and a social worker who connects with patients in the community to help identify and address both their medical and social needs. Results show that patients managed through the initiative have decreased emergency department and hospital utilization and improved management of health conditions. The initiative has also been successful in connecting patients to primary care following a hospital discharge.
The Harlem Children’s Zone (HCZ) Project is a multi-dimensional, place-based approach to developing a healthy neighborhood and supporting the healthy development of children from birth to adulthood. The program focuses on children within a 100-block area in Central Harlem that had chronic disease and infant mortality rates that exceeded rates for many other sections of the city as well as high rates of poverty and unemployment. HCZ seeks to improve the educational, economic, and health outcomes of the community through a broad range of family, social service, and health programs. Programs include training and education of expectant parents, full-day pre-K, community centers that offer after-school and weekend programming, nutrition education, recreation options, and food services that provide healthy meals to students. HCZ tracks metrics across its initiatives and reports a 92% college acceptance rate across its programs.
In Colorado, the Colorado Health Foundation is leading an initiative called Healthy Places: Designing an Active Colorado. This initiative aims to reduce obesity by fostering a built environment that supports physical activity and connectivity within three communities. Examples of projects implemented under this initiative include building new parks, playgrounds and walking trails; creating new family-based recreational opportunities; and increasing bicycle and pedestrian infrastructure.
The Healthy Food Financing Initiative is a public-private partnership that has leveraged over $1 billion to support over 200 projects in over 30 states since 2011 to improve access to healthy foods in low-income communities. Pilot studies for the Philadelphia Healthy Corner Store Initiative, now bringing healthier products to over 600 corner stores, showed a 60% increase in the sales of fresh produce. In addition, they demonstrated increased local economic activity and jobs and generation of local tax revenue.
Health in All Policies
Since the early 2000s, there has been a growing movement in the public health community to adopt a Health in All Policies
approach. This approach recognizes the need to address social determinants of health to improve population health and seeks to ensure that decision-makers across different sectors are informed about the health, equity, and sustainability consequences of policy decisions in non-health sectors. In much the same way that environmental impact assessments allow for evaluation of the environmental impact of policies, health impact assessments evaluate the health impact of policies and practices across sectors that have not traditionally considered their impact on health.
Policies and practices in areas as diverse as education and early child development, economic and community development, transportation, and agricultural and food policy all have impacts on health and health equity. For example, providing early childhood education programs to children in low-income and racial and ethnic minority communities helps to reduce achievement gaps, improve the health of low-income students, and promote health equity. The availability and accessibility of public transportation affects access to employment, affordable healthy foods, health care, and other important drivers of health and wellness. Policies and practices in food policy can also promote health by supporting healthier corner stores in low-income communities, farm to school programs and community and school gardens, as well as through broader efforts to support the production and consumption of healthy foods.
Health in All Policies approaches are being promoted and implemented at the federal level, by local and state governments, community organizations, and funders. The National Prevention Council, created by the ACA, for the first time brings together senior leadership from 20 federal departments, agencies, and offices around a shared health agenda. Under the leadership of the Surgeon General, the council developed the National Prevention Strategy, identifying collaborative opportunities through a public health lens to advance health and wellness across all federal agencies. Similar approaches are being adopted at the state level. The California Health in All Policies Task Force was established by executive order in 2010 with the goal of bringing together 22 state agencies, departments, and offices to support a healthier and more sustainable California. The task force has developed interagency initiatives focused on crime prevention, access to healthy food, and active transportation. In 2010, King County, Washington, adopted an ordinance that codified bringing a health and health equity lens—a fair and just
principle—to the county’s new strategic plan. Through this prioritization of health equity across all policies, the county has focused on issues ranging from educational attainment and workforce development to affordable transit. National and local funders are also shifting focus to support broader policies and practices that promote opportunities for health. For example, the Robert Wood Johnson Foundation underwent a major strategic reorientation aligned with its vision of building a national Culture of Health.
This vision seeks to look beyond health care to improve population health and change the way the nation thinks about health by focusing on collective impact and cross sector collaboration in areas ranging from early childhood education to food access and community development.
THE SOCIAL JUSTICE COMMITMENT
Like medicine, public health is not a purely positivistic pursuit. It is fundamentally driven by its progressive aim: to prevent disease, injury, and premature death. Its aggregative approach to measuring success may at first glance appear to be utilitarian. But, as the preceding excerpt demonstrates, public health is deeply interested in the distribution of good and ill health within populations. Improving aggregate health status by further improving the health of the privileged few is not the aim of public health. Rather, the aim is to shift the whole distribution of disease and injury downward, as Rose describes.
Deep and enduring socioeconomic disparities in health form the backdrop to any public health policy, and these disparities help explain why social justice is a core value of public health. As Angus Deaton (2002, 13) explains, Poorer people die younger and are sicker than richer people; indeed, mortality and morbidity rates are inversely related to many correlates of socioeconomic status [SES] such as income, wealth, education, or social class.
Scholars often use the term health-wealth gradient to refer the correlation between SES and health to reflect the frequently demonstrated trend whereby health improves more or less continuously as SES increases. British epidemiologist Sir Michael Marmot (2006) offers a powerful illustration of the SES gradient. For every mile traveled on the Metro’s Red Line in the District of Columbia from the impoverished northeast to the affluent northwest, average life expectancy increases by one and a half years. Marmot’s pioneering work on the social determinants of health has had enormous influence on the science, practice, ethics, and law of public health.
Social disparities in health outcomes are of interest for a number of reasons. An association between heart disease rates and household income indicates that modifiable factors are at work, highlighting the potential for disruption of causal pathways and prevention of unnecessary illness and premature death. A difference in cancer mortality between Black women and non-Hispanic white women could indicate a genetic difference, but given the nature of race as a construct having more to do with social position than biological difference, it is at least as likely to indicate that social determinants are influencing outcomes. Even more importantly, these disparities are unconscionable because poor health limits the capabilities of individuals and communities to achieve their self-defined aims in life. Social, economic, and cultural disadvantages may compound health disparities and vice versa.
The excerpts that follow explore the commitment of public health practice, policy, and ethics to social justice, which has both a distributive (fairness in the distribution of benefits and burdens) and a participatory (fairness in the representation and recognition of diverse voices and interests in the identification and evaluation of priorities and interventions) dimension. The commitment to social justice is intertwined with public health’s focus on communities both as the objects of its inquiries and interventions and as participatory subjects in democratic processes of identifying priorities, developing interventions, and evaluating both. Public health’s commitment to social justice, augmented by the relatively new scientific methods of social epidemiology, has led to growing understanding of the social determinants of health over the last few decades. In turn, this understanding is shaping the boundaries of public health science, practice, and law.
We begin with Paula Braveman and her coauthors, who discuss the crucial and challenging task of defining health disparities and health equity as a foundation for social justice in public health.
