Measures of biological variation have long been associated with many indices of social inequality. Data on health, nutrition, fertility, mortality, physical fitness, intellectual performance and a range of heritable biological markers show the ubiquity of such patterns across time, space and population. This volume reviews the current evidence for the strength of such linkages and the biological and social mechanisms that underlie them. A major theme is the relationship between the proximate determinants of these linkages and their longer-term significance for biologically selective social mobility. This book therefore addresses the question of how social stratification mediates processes of natural selection in human groups. Data like this pose difficult and sensitive issues for health policy and developments in this area and in eugenics are reviewed for industrialised and developing countries.
Social scientists have repeatedly uncovered a disturbing feature of economic inequality: people with larger incomes and better education tend to lead longer, healthier lives. This pattern holds across all ages and for virtually all measures of health, apparently indicating a biological dimension of inequality. But scholars have only begun to understand the complex mechanisms that drive this disparity. How exactly do financial well-being and human physiology interact? The Biological Consequences of Socioeconomic Inequalities incorporates insights from the social and biological sciences to quantify the biology of disadvantage and to assess how poverty gets under the skin to impact health. Drawing from unusually rich datasets of biomarkers, brain scans, and socioeconomic measures, Biological Consequences of Socioeconomic Inequalities illustrates exciting new paths to understanding social inequalities in health. Barbara Wolfe, William N. Evans and Nancy Adler begin the volume with a critical evaluation of the literature on income and health, providing a lucid review of the difficulties of establishing clear causal pathways between the two variables. In their chapter, Arun S. Karlamangla, Tara L. Gruenewald, and Teresa E. Seeman outline the potential of biomarkers—such as cholesterol, heart pressure, and C-reactive protein—to assess and indicate the factors underlying health. Edith Chen, Hannah M. C. Schreier, and Meanne Chan reveal the empirical power of biomarkers by examining asthma, a condition steeply correlated with socioeconomic status. Their analysis shows how stress at the individual, family, and neighborhood levels can increase the incidence of asthma. The volume then turns to cognitive neuroscience, using biomarkers in a new way to examine the impact of poverty on brain development. Jamie Hanson, Nicole Hair, Amitabh Chandra, Ed Moss, Jay Bhattacharya, Seth D. Pollack, and Barbara Wolfe use a longitudinal Magnetic Resonance Imaging (MRI) study of children between the ages of four and eighteen to study the link between poverty and limited cognition among children. Michelle C. Carlson, Christopher L. Seplaki, and Teresa E. Seeman also focus on brain development to examine the role of socioeconomic status in cognitive decline among older adults. Featuring insights from the biological and social sciences, Biological Consequences of Socioeconomic Inequalities will be an essential resource for scholars interested in socioeconomic disparities and the biological imprint that material deprivation leaves on the human body.
In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.
The Oxford Handbook of Economics and Human Biology provides an extensive and insightful overview of how economic conditions affect human well-being and how human health influences economic outcomes. The book addresses both macro and micro factors, as well as their interaction, providing new understanding of complex relationships and developments in economic history and economic dynamics. Among the topics explored is how variation in height, whether over time, among different socioeconomic groups, or in different locations, is an important indicator of changes in economic growth and economic development, levels of economic inequality, and economic opportunities for individuals.
Inequality in income, earnings, and wealth has risen dramatically in the United States over the past three decades. Most research into this issue has focused on the causes—global trade, new technology, and economic policy—rather than the consequences of inequality. In Social Inequality, a group of the nation's leading social scientists opens a wide-ranging inquiry into the social implications of rising economic inequality. Beginning with a critical evaluation of the existing research, they assess whether the recent run-up in economic inequality has been accompanied by rising inequality in social domains such as the quality of family and neighborhood life, equal access to education and health care, job satisfaction, and political participation. Marcia Meyers and colleagues find that many low-income mothers cannot afford market-based child care, which contributes to inequality both at the present time—by reducing maternal employment and family income—and through the long-term consequences of informal or low-quality care on children's educational achievement. At the other end of the educational spectrum, Thomas Kane links the growing inequality in college attendance to rising tuition and cuts in financial aid. Neil Fligstein and Taek-Jin Shin show how both job security and job satisfaction have decreased for low-wage workers compared with their higher-paid counterparts. Those who fall behind economically may also suffer diminished access to essential social resources like health care. John Mullahy, Stephanie Robert, and Barbara Wolfe discuss why higher inequality may lead to poorer health: wider inequality might mean increased stress-related ailments for the poor, and it might also be associated with public health care policies that favor the privileged. On the political front, Richard Freeman concludes that political participation has become more stratified as incomes have become more unequal. Workers at the bottom of the income scale may simply be too hard-pressed or too demoralized to care about political participation. Social Inequality concludes with a comprehensive section on the methodological problems involved in disentangling the effects of inequality from other economic factors, which will be of great benefit to future investigators. While today's widening inequality may be a temporary episode, the danger is that the current economic divisions may set in motion a self-perpetuating cycle of social disadvantage. The most comprehensive review of this quandary to date, Social Inequality maps out a new agenda for research on inequality in America with important implications for public policy.
Thanks to advances in technology, medicine, Social Security, and Medicare, old age for many Americans is characterized by comfortable retirement, good health, and fulfilling relationships. But there are also millions of people over 65 who struggle with poverty, chronic illness, unsafe housing, social isolation, and mistreatment by their caretakers. What accounts for these disparities among older adults? Sociologist Deborah Carr’s Golden Years? draws insights from multiple disciplines to illuminate the complex ways that socioeconomic status, race, and gender shape the nearly every aspect of older adults’ lives. By focusing on an often-invisible group of vulnerable elders, Golden Years? reveals that disadvantages accumulate across the life course and can diminish the well-being of many. Carr connects research in sociology, psychology, epidemiology, gerontology, and other fields to explore the well-being of older adults. On many indicators of physical health, such as propensity for heart disease or cancer, black seniors fare worse than whites due to lifetimes of exposure to stressors such as economic hardships and racial discrimination and diminished access to health care. In terms of mental health, Carr finds that older women are at higher risk of depression and anxiety than men, yet older men are especially vulnerable to suicide, a result of complex factors including the rigid masculinity expectations placed on this generation of men. Carr finds that older adults’ physical and mental health are also closely associated with their social networks and the neighborhoods in which they live. Even though strong relationships with spouses, families, and friends can moderate some of the health declines associated with aging, women—and especially women of color—are more likely than men to live alone and often cannot afford home health care services, a combination that can be isolating and even fatal. Finally, social inequalities affect the process of dying itself, with white and affluent seniors in a better position to convey their end-of-life preferences and use hospice or palliative care than their disadvantaged peers. Carr cautions that rising economic inequality, the lingering impact of the Great Recession, and escalating rates of obesity and opioid addiction, among other factors, may contribute to even greater disparities between the haves and the have-nots in future cohorts of older adults. She concludes that policies, such as income supplements for the poorest older adults, expanded paid family leave, and universal health care could ameliorate or even reverse some disparities. A comprehensive analysis of the causes and consequences of later-life inequalities, Golden Years? demonstrates the importance of increased awareness, strong public initiatives, and creative community-based programs in ensuring that all Americans have an opportunity to age well.
Does biology help explain why women, on average, earn less money than men? Is there any evolutionary basis for the scarcity of female CEOs in Fortune 500 companies? According to Kingsley Browne, the answer may be yes. Biology at Work brings an evolutionary perspective to bear on issues of women in the workplace: the "glass ceiling," the "gender gap" in pay, sexual harassment, and occupational segregation. While acknowledging the role of discrimination and sexist socialization, Browne suggests that until we factor real biological differences between men and women into the equation, the explanation remains incomplete. Browne looks at behavioral differences between men and women as products of different evolutionary pressures facing them throughout human history. Womens biological investment in their offspring has led them to be on average more nurturing and risk averse, and to value relationships over competition. Men have been biologically rewarded, over human history, for displays of strength and skill, risk taking, and status acquisition. These behavioral differences have numerous workplace consequences. Not surprisingly, sex differences in the drive for status lead to sex differences in the achievement of status. Browne argues that decision makers should recognize that policies based on the assumption of a single androgynous human nature are unlikely to be successful. Simply removing barriers to inequality will not achieve equality, as women and men typically value different things in the workplace and will make different workplace choices based on their different preferences. Rather than simply putting forward the "nature" side of the debate, Browne suggests that dichotomies such as nature/nurture have impeded our understanding of the origins of human behavior. Through evolutionary biology we can understand not only how natural selection has created predispositions toward certain types of behavior but also how the social environment interacts with these predispositions to produce observed behavioral patterns.
How genomics reveals deep histories of inequality, going back many thousands of years. Inequality is an urgent global concern, with pundits, politicians, academics, and best-selling books all taking up its causes and consequences. In Inequality, Carles Lalueza-Fox offers an entirely new perspective on the subject, examining the genetic marks left by inequality on humans throughout history. Lalueza-Fox describes genetic studies, made possible by novel DNA sequencing technologies, that reveal layers of inequality in past societies, manifested in patterns of migration, social structures, and funerary practices. Through their DNA, ancient skeletons have much to tell us, yielding anonymous stories of inequality, bias, and suffering. Lalueza-Fox, a leader in paleogenomics, offers the deep history of inequality. He explores the ancestral shifts associated with migration and describes the gender bias unearthed in these migrations—the brutal sexual asymmetries, for example, between male European explorers and the women of Latin America that are revealed by DNA analysis. He considers social structures, and the evidence that high social standing was inherited—the ancient world was not a meritocracy. He untangles social and genetic factors to consider whether wealth is an advantage in reproduction, showing why we are more likely to be descended from a king than a peasant. And he explores the effects of ancient inequality on the human gene pool. Marshaling a range of evidence, Lalueza-Fox shows that understanding past inequalities is key to understanding present ones.
Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. Nessa Carey, a leading epigenetics researcher, connects the field's arguments to such diverse phenomena as how ants and queen bees control their colonies; why tortoiseshell cats are always female; why some plants need cold weather before they can flower; and how our bodies age and develop disease. Reaching beyond biology, epigenetics now informs work on drug addiction, the long-term effects of famine, and the physical and psychological consequences of childhood trauma. Carey concludes with a discussion of the future directions for this research and its ability to improve human health and well-being.
