Environmental health disparities in housing

The physical infrastructure and housing make human interaction possible and provide shelter. How well that infrastructure performs and which groups it serves have important implications for social equity and health. Populations in inadequate housing are more likely to have environmental diseases and injuries. Substantial disparities in housing have remained largely unchanged. Approximately 2.6 million (7.5%) non-Hispanic Blacks and 5.9 million Whites (2.8%) live in substandard housing. Segregation, lack of housing mobility, and homelessness are all associated with adverse health outcomes. Yet the experience with childhood lead poisoning in the United States has shown that housing-related disparities can be reduced. Effective interventions should be implemented to reduce environmental health disparities related to housing.     

Environmental health disparities: a framework integrating psychosocial and environmental concepts

Although it is often acknowledged that social and environmental factors interact to produce racial and ethnic environmental health disparities, it is still unclear how this occurs. Despite continued controversy, the environmental justice movement has provided some insight by suggesting that disadvantaged communities face greater likelihood of exposure to ambient hazards. The exposure-disease paradigm has long suggested that differential "vulnerability" may modify the effects of toxicants on biological systems. However, relatively little work has been done to specify whether racial and ethnic minorities may have greater vulnerability than do majority populations and, further, what these vulnerabilities may be. We suggest that psychosocial stress may be the vulnerability factor that links social conditions with environmental hazards. Psychosocial stress can lead to acute and chronic changes in the functioning of body systems (e.g., immune) and also lead directly to illness. In this article we present a multidisciplinary framework integrating these ideas. We also argue that residential segregation leads to differential experiences of community stress, exposure to pollutants, and access to community resources. When not counterbalanced by resources, stressors may lead to heightened vulnerability to environmental hazards.     

Socioeconomic disparities in the mental health of Indigenous children in Western Australia

ABSTRACT: BACKGROUND: The burden of mental health problems among Aboriginal and Torres Strait Islander children is a major public health problem in Australia. While socioeconomic factors are implicated as important determinants of mental health problems in mainstream populations, their bearing on the mental health of Indigenous Australians remains largely uncharted across all age groups. METHODS: We examined the relationship between the risk of clinically significant emotional or behavioural difficulties (CSEBD) and a range of socioeconomic measures for 3993 Indigenous children aged 4--17 years in Western Australia, using a representative survey conducted in 2000--02. Analysis was conducted using multivariate logistic regression within a multilevel framework. RESULTS: Almost one quarter (24%) of Indigenous children were classified as being at high risk of CSEBD. Our findings generally indicate that higher socioeconomic status is associated with a reduced risk of mental health problems in Indigenous children. Housing quality and tenure and neighbourhood-level disadvantage all have a strong direct effect on child mental health. Further, the circumstances of families with Indigenous children (parenting quality, stress, family composition, overcrowding, household mobility, racism and family functioning) emerged as an important explanatory mechanism underpinning the relationship between child mental health and measures of material wellbeing such as carer employment status and family financial circumstances. CONCLUSIONS: Our results provide incremental evidence of a social gradient in the mental health of Aboriginal and Torres Strait Islander children. Improving the social, economic and psychological conditions of families with Indigenous children has considerable potential to reduce the mental health inequalities within Indigenous populations and, in turn, to close the substantial racial gap in mental health. Interventions that target housing quality, home ownership and neighbourhood-level disadvantage are likely to be particularly beneficial.     

Engendering health disparities

How is gender implicated in our exploration of health disparities in Canada? Set against the backdrop of federal government policy, this review paper examines the ways in which gender intersects with other health determinants to produce disparate health outcomes. An overview of salient issues including the impact of gender roles, environmental exposures, gender violence, workplace hazards, economic disparities, the costs of poverty, social marginalization and racism, aging, health conditions, interactions with health services, and health behaviours are considered. This review suggests health is detrimentally affected by gender roles and statuses as they intersect with economic disparities, cultural, sexual, physical and historical marginalization as well as the strains of domestic and paid labour. These conditions result in an unfair health burden borne in particular by women whose access to health determinants is--in various degrees--limited. While progress has certainly been made on some fronts, the persistence of health disparities among diverse populations of women and men suggests a postponement of the vision of a just society with health for all that was articulated in the Federal Plan on Gender Equality. Commitment, creativity and collaboration from stakeholders ranging from various levels of government, communities, academics, non-governmental agencies and health professionals will be required to reduce and eliminate health disparities between and among all members of our society.     

Family environment and dental health disparities among urban children in Burkina Faso

BackgroundDental caries is the most common multifactorial disease in children and has substantial negative impact on daily life. In sub-Saharan Africa, few data are available on the relationship between dental caries and the social and family environment of children. The objectives of the present study were firstly to assess the level of prevalence and severity of dental caries of children in Ouagadougou, the capital city of Burkina Faso and secondly to determine whether or not individual factors, family and living conditions are linked with dental health disparities within the population.MethodsInterview and clinical data were obtained from a household-based cross-sectional survey. A two-stage stratified sampling technique was applied in four areas of Ouagadougou representing different stages of urbanization.ResultsThe final study population included 1606 children aged 6–12 years. For the overall group the total caries prevalence rate was 48.2%. Results showed that the dental health status of the mother, social integration of the householder and socioeconomic level of the household were associated with the dental health of children. Disparities in dental health were prominent; poor dental health was relatively frequent in children from households poorly integrated into social networks with rather acceptable standard in terms of material wealth.ConclusionOur study showed that individual factors as well as family-related and environmental factors had an influence on their caries experience. The rapidly changing lifestyle affects oral health and the burden of oral diseases is expected to increase initially in people of upper classes and later in disadvantaged people. Disease prevention focussing on common risk factors of chronic diseases should be enhanced. In addition, the accessibility of quality fluoride products (e.g. toothpaste, salt, water) should be facilitated as soon as possible.     

Cancer-related health disparities in women

OBJECTIVES: This article synthesizes information about cancer in 9 populations of minority women: Mexican American, Puerto Rican, Cuban American, African American, Asian American, Native Hawaiian, American Samoan, American Indian, and Alaska Native. METHODS: Cancer registry data, social indicators, government sources, and published articles were searched for information on the background and cancer experience of these 9 racial/ethnic groups. RESULTS: Approximately 35 million women in these racial/ethnic groups live in the United States, and their numbers are increasing rapidly. Since 1992, incidence rates for major cancer sites have slowed or decreased among these groups, but declines in mortality have not occurred or have been smaller than for Whites. Gaps in early detection have narrowed, but minority women still lag behind Whites. Smoking and obesity remain common in these populations. CONCLUSIONS: More culturally appropriate interventions and research are needed, and these efforts must involve the community and raise the quality of health services.     

Racial/ethnic health disparities among children with special health care needs in Boston,Massachusetts

BackgroundLittle is known about the factors that contribute to racial/ethnic disparities among children with special health care needs (CSHCN).ObjectiveTo quantify the contributions of determinants of racial/ethnic disparities in health and health care among CSHCN in Boston, Massachusetts.MethodsA sample of 326 Black, Latino, and white CSHCN was drawn from the Boston Survey of Children's Health, a city-wide representative sample of children. The study implemented Oaxaca–Blinder-style decomposition techniques to examine the relative contributions of health resources and child-, family-, and neighborhood-level factors to disparities in four outcomes: health status, barriers to medical care, oral health status, and utilization of preventive dental care.ResultsWhite CSHCN had a greater likelihood of having very good/excellent health and oral health and were less likely to experience barriers to care than Black CSHCN. Compositional differences on predictors explained 63%, 98%, and 80% of these gradients, respectively. Group variation in household income, family structure, neighborhood support, and exposure to adverse childhood experiences accounted for significant portions of the Black–white gaps in health and access. White CSHCN were also more likely to have very good/excellent health and oral health compared to Latino CSHCN. Differences on predictors accounted for about 86% and 80% of these gaps, respectively. Household income, adverse childhood experiences, and household language emerged as significant determinants of Latino–white disparities.ConclusionsRacial/ethnic health disparities among CSHCN are explained by relatively few determinants. Several of the contributing factors that emerged from the analysis and could be targeted by public health and policy interventions.     

The public health approach to eliminating disparities in health

Reducing and eliminating disparities in health is a matter of life and death. Each year in the United States, thousands of individuals die unnecessarily from easily preventable diseases and conditions. It is critical that we approach this problem from a broad public health perspective, attacking all of the determinants of health: access to care, behavior, social and physical environments, and overriding policies of universal access to care, physical education in schools, and restricted exposure to toxic substances. We describe the historical background for recognizing and addressing disparities in health, various factors that contribute to disparities, how the public health approach addresses such challenges, and two successful programs that apply the public health approach to reducing disparities in health. Public health leaders must advocate for public health solutions to eliminate disparities in health.     

Socioeconomic disparities in physical health among Aboriginal and Torres Strait Islander children in Western Australia

Objective. Few empirical studies have specifically examined the relationship between socio-economic status (SES) and health in Indigenous populations of Australia. We sought to provide insights into the nature of this relationship by examining socio-economic disparities in physical health outcomes among Aboriginal and Torres Strait Islander children in Western Australia.

Design. We used a diverse set of health and SES indicators from a representative survey conducted in 2000–2002 on the health and development of 5289 Indigenous children aged 0–17 years in Western Australia. Analysis was conducted using multivariate logistic regression within a multilevel framework.

Results. After controlling for age and sex, we found statistically significant socio-economic disparities in health in almost half of the associations that were investigated, although the direction, shape and magnitude of associations differed. For ear infections, recurring chest infections and sensory function problems, the patterns were generally consistent with a positive socio-economic gradient – where better health was associated with higher SES. The reverse pattern was found for asthma, accidents and injuries, and oral health problems, although this was primarily observed for area-level SES indicators.

Conclusion. Conventional notions of social position and class have some influence on the physical health of Indigenous children, although the diversity of results implies that there are other ways of conceptualising and measuring SES that are important for Indigenous populations. We need to consider factors that relate specifically to Indigenous circumstances and culture in the past and present day, and give more thought to how we measure social position in the Indigenous community, to gain a better understanding of the pathways from SES to Indigenous child health.     

Confronting oral health disparities among American Indian/Alaska Native children: the pediatric oral health therapist

American Indian and Alaska Native (AIAN) children are disproportionately affected by oral disease compared with the general population of American children. Additionally, AIAN children have limited access to professional oral health care. The Indian Health Service (IHS) and AIAN tribal leaders face a significant problem in ensuring care for the oral health of these children.We discuss the development and deployment of a new allied oral health professional, a pediatric oral health therapist. This kind of practitioner can effectively extend the ability of dentists to provide for children not receiving care and help to confront the significant oral health disparities existing in AIAN children.Resolving oral health disparities and ensuring access to oral health care for American Indians and Alaska Natives is a moral issue-one of social justice.     

Social sources of racial disparities in health

Racial disparities in mortality over time reflect divergent pathways to the current large racial disparities in health. The residential concentration of African Americans is high and distinctive, and the related inequities in neighborhood environments, socioeconomic circumstances, and medical care are important factors in initiating and maintaining racial disparities in health. Efforts are needed to identify and maximize health-enhancing resources that may reduce some of the negative effects of psychosocial factors on health. Health and health disparities are embedded in larger historical, geographic, sociocultural, economic, and political contexts. Changes in a broad range of public policies are likely to be central to effectively addressing racial disparities.     

Approaches to eliminating sociocultural disparities in health

The recent flurry of studies documenting the presence of racial, ethnic, and socioeconomic disparities in health care and health have outpaced articles that describe effective strategies to eliminate disparities. Through literature review and informal interviews with research, policy, and program experts, we developed a framework of programs that address disparities through targeting clinicians, patients and communities, and health systems. We found that the lack of technical expertise, resources, and sensitive tools are all common barriers to evaluating programs. To stimulate more effective programs and rigorous evaluations, we describe specialized implementation and evaluation techniques programs can use, and make recommendations for future efforts.     

Improving population health and reducing health care disparities

The first goal of Healthy People 2010, to increase quality and years of healthy life, does not necessarily coincide with the second goal, to eliminate disparities among population groups. Improvement in the health of the total population without any reduction in relative disparities among racial and ethnic groups was the most frequent outcome at mid-decade for population-based Healthy People objectives. Strategies to maximize improvement in overall population health may have little or no impact on relative disparities or, indeed, may cause them to increase. An independent commitment to eliminating disparities may be necessary.     

One health disparities and COVID-19

 The global impact of the COVID-19 pandemic has disproportionately affected some communities and populations more than others. We propose that an interdisciplinary framework of ‘One Health Disparities’ advances understanding of the social and systemic issues that drive COVID-19 in vulnerable populations. One Health Disparities integrates the social environment with One Health perspectives on the interconnectedness of human, animal, and environmental health. To apply this framework, we consider One Health Disparities that emerge in three key components of disease transmission: exposure, susceptibility, and disease expression. Exposure disparities arise through variation in contact with COVID-19’s causative agent, SARS-CoV-2. Disparities in susceptibility and disease expression also exist; these are driven by biological and social factors, such as diabetes and obesity, and through variation in access to healthcare. We close by considering how One Health Disparities informs understanding of spillback into new animal reservoirs, and what this might mean for further human health disparities.Lay summaryOne Health focuses on interconnections between human, animal, and environmental health. We propose that social environments are also important to One Health and help illuminate disparities in the coronavirus pandemic, including its origins, transmission and susceptibility among humans, and spillback to other species. We call this framework One Health Disparities.
