Uses of theory in racial health disparities research: a scoping review and application of public health critical race praxis.

PURPOSE: Given the persistence of racial health disparities, scholars have called for investigations into structural origins of health inequity and deeper engagement with theory. We systematically assessed uses of theory-including theory informed conceptualizations of race and ethnicity, social structure, and racial hierarchy-in epidemiology and other quantitative population health literature on racial health disparities. METHODS: We conducted a scoping review of systematically identified original research articles (n=650) that sought to explain racial health disparities; articles were published in 17 high-impact epidemiology, public health, and social science journals. Trained coders abstracted data from each article. We applied Public Health Critical Race Praxis and an iterative data-charting method to identify key themes. RESULTS: Only 63 (9.7%) of 650 racial health disparities articles explicitly used theory. Among studies that engaged theory, one third (n=21/63) clearly conceptualized race and/or ethnicity, and a minority theorized social structure (n=19/63; 30%) and/or racial hierarchy as a structural relation (n=4/63; 6%). CONCLUSIONS: There is a pressing need for racial health disparities researchers to unambiguously use theory to conceptualize race and ethnicity in social and historical contexts and explain relational aspects of racial hierarchy. These approaches can better elucidate and inform action on structural determinants of both racial inequity and racial health inequity.

Intimate Partner Violence and Structural Violence in the Lives of Incarcerated Women: A Mixed-Method Study in Rural New Mexico.

Intimate partner violence (IPV) is a common feature in the lives of incarcerated women returning to rural communities, enhancing their risk of mental ill-health, substance use, and recidivism. Women's experiences of IPV intersect with challenges across multiple social-ecological levels, including risky or criminalizing interpersonal relationships, geographic isolation, and persistent gender, racial, and economic inequities. We conducted quantitative surveys and qualitative interviews with 99 incarcerated women in New Mexico who were scheduled to return to micropolitan or non-core areas within 6 months. Quantitative and qualitative data were analyzed separately and then triangulated to identify convergences and divergences in data. The findings underscore how individual and interpersonal experiences of IPV, substance use, and psychological distress intersect with broad social inequities, such as poverty, lack of supportive resources, and reluctance to seek help due to experiences of discrimination. These results point to the need for a more proactive response to the mutually constitutive cycle of IPV, mental distress, incarceration, and structures of violence to improve reentry for women returning to rural communities. Policy and treatment must prioritize socioeconomic marginalization and expand community resources with attention to the needs of rural women of color.

The legacy of structural racism: Associations between historic redlining, current mortgage lending, and health.

Structural racism, which is embedded in past and present operations of the U.S. housing market, is a fundamental cause of racial health inequities. We conducted an ecologic study to 1) examine historic redlining in relation to current neighborhood lending discrimination and three key indicators of societal health (mental health, physical health, and infant mortality rate (IMR)) and 2) investigate sustained lending disinvestment as a determinant of current neighborhood health in one of the most hypersegregated metropolitan areas in the United States, Milwaukee, Wisconsin. We calculated weighted historic redlining scores from the proportion of 1930s Home Owners' Loan Corporation residential security grades contained within 2010 census tract boundaries. We combined two lending indicators from 2018 Home Mortgage Disclosure Act data to capture current neighborhood lending discrimination: low lending occurrence and high cost loans (measured via loan rate spread). Using historic redlining score and current lending discrimination, we created a 4-level hierarchical measure of lending trajectory. In Milwaukee neighborhoods, greater historic redlining was associated with current lending discrimination (OR = 1.73, 95%CI: 1.16, 2.58) and increased prevalence of poor physical health (ß = 1.34, 95%CI: 0.40, 2.28) and poor mental health (ß = 1.26, 95%CI: 0.51, 2.01). Historic redlining was not associated with neighborhood IMR (ß = -0.48, 95%CI: -2.12, 1.15). A graded association was observed between lending trajectory and health: neighborhoods with high sustained disinvestment had worse physical and mental health than neighborhoods with high investment (poor physical health: ß = 5.33, 95%CI: 3.05, 7.61; poor mental health: ß = 4.32, 95%CI: 2.44, 6.20). IMR was highest in 'disinvested' neighborhoods (ß = 5.87, 95%CI: 0.52, 11.22). Our findings illustrate ongoing legacies of government sponsored historic redlining. Structural racism, as manifested in historic and current forms of lending disinvestment, predicts poor health in Milwaukee's hypersegregated neighborhoods. We endorse equity focused policies that dismantle and repair the ways racism is entrenched in America's social fabric.

Intersectionality Research for Transgender Health Justice: A Theory-Driven Conceptual Framework for Structural Analysis of Transgender Health Inequities.

Transgender people experience intersecting forms of social marginalization and are disproportionately affected by health inequities. We elucidate a novel conceptual framework for transgender health research that theorizes the constructs and pathways through which social inequities produce health inequities for transgender populations. Drawing on theories of intersectionality and structural injustice, Intersectionality Research for Transgender Health Justice (IRTHJ) posits that social and health inequities affecting transgender populations are the result of status quo power relations produced within and between oppressive structures, institutional systems, and socio-structural processes. The IRTHJ framework delineates three main actions for improving transgender health research: (i) name intersecting power relations, (ii) disrupt the status quo, and (iii) center embodied knowledge. The authors show how IRTHJ provides tools for researchers to transform the design, implementation, and interpretation of transgender health research, and they discuss implications for programs, policy, and action for transgender health justice.

Exploring traditional end-of-life beliefs, values, expectations, and practices among Chinese women living in England: Informing culturally safe care.

OBJECTIVE: This study explores the end-of-life (EoL) beliefs, values, practices, and expectations of a select group of harder-to-reach Chinese women living in England. METHOD: A cultural safety approach was undertaken to interpret 11 in-depth, semistructured interviews. Interviews were conducted in Mandarin and Cantonese. Transcripts were translated and back-translated by two researchers. Findings were analyzed using the technical analytical principles of grounded theory. RESULTS: The key themes generated from our analysis include: acculturation; differential beliefs and norms in providing care: family versus health services; language and communication; Eastern versus Western spiritual practices and beliefs; and dying, death, and the hereafter. SIGNIFICANCE OF RESULTS: End-of-life discussions can be part of an arduous, painful, and uncomfortable process, particularly for migrants living on the margins of society in a new cultural setting. For some Chinese people living in the United Kingdom, end-of-life care requires attention to acculturation, particularly Western versus Eastern beliefs on religion, spirituality, burial practices, and provision of care, and the availability of culturally specific care, all of which encompass issues related to gender. Stories of a purposive sample of Chinese women were viewed through a cultural safety lens to gain a deeper understanding of how social and cultural norms and expectations, in addition to the pressures of acculturation, impact gendered roles and responsibilities. The analysis revealed variations between/within Eastern and Western culture that resulted in pronounced, and oftentimes gendered, differences in EoL care expectations.

Explaining aboriginal/non-aboriginal inequalities in postseparation violence against Canadian women: application of a structural violence approach.

Adopting a structural violence approach, we analyzed 2004 Canadian General Social Survey data to examine Aboriginal/non-Aboriginal inequalities in postseparation intimate partner violence (IPV) against women. Aboriginal women had 4.12 times higher odds of postseparation IPV than non-Aboriginal women (p < .001). Coercive control and age explained most of this inequality. The final model included Aboriginal status, age, a seven-item coercive control index, and stalking, which reduced the odds ratio for Aboriginal status to 1.92 (p = .085) and explained 70.5% of the Aboriginal/non-Aboriginal inequality in postseparation IPV. Research and action are needed that challenge structural violence, especially colonialism and its negative consequences.

Investigating maternal risk factors as potential targets of intervention to reduce socioeconomic inequality in small for gestational age: a population-based study.

BACKGROUND: The major aim of this study was to investigate whether maternal risk factors associated with socioeconomic status and small for gestational age (SGA) might be viable targets of interventions to reduce differential risk of SGA by socioeconomic status (socioeconomic SGA inequality) in the metropolitan area of Vancouver, Canada. METHODS: This study included 59,039 live, singleton births in the Vancouver Census Metropolitan Area (Vancouver) from January 1, 2006 to September 17, 2009. To identify an indicator of socioeconomic SGA inequality, we used hierarchical logistic regression to model SGA by area-level variables from the Canadian census. We then modelled SGA by area-level average income plus established maternal risk factors for SGA and calculated population attributable SGA risk percentages (PAR%) for each variable. Associations of maternal risk factors for SGA with average income were investigated to identify those that might contribute to SGA inequality. Finally, we estimated crude reductions in the percentage and absolute differences in SGA risks between highest and lowest average income quintiles that would result if interventions on maternal risk factors successfully equalized them across income levels or eliminated them altogether. RESULTS: Average income produced the most linear and statistically significant indicator of socioeconomic SGA inequality with 8.9% prevalence of SGA in the lowest income quintile compared to 5.6% in the highest. The adjusted PAR% of SGA for variables were: bottom four quintiles of height (51%), first birth (32%), bottom four quintiles of average income (14%), oligohydramnios (7%), underweight or hypertension, (6% each), smoking (3%) and placental disorder (1%). Shorter height, underweight and smoking during pregnancy had higher prevalence in lower income groups. Crude models assuming equalization of risk factors across income levels or elimination altogether indicated little potential change in relative socioeconomic SGA inequality and reduction in absolute SGA inequality for shorter height only. CONCLUSIONS: Our findings regarding maternal height may indicate trans-generational aetiology for socioeconomic SGA inequalities and/or that adult height influences social mobility. Conditions affecting foetal and childhood growth might be viable targets to reduce absolute socioeconomic SGA inequality in future generations, but more research is needed to determine whether such an approach is appropriate.

Cesarean delivery in Native American women: are low rates explained by practices common to the Indian health service?

BACKGROUND: Studying populations with low cesarean delivery rates can identify strategies for reducing unnecessary cesareans in other patient populations. Native American women have among the lowest cesarean delivery rates of all United States populations, yet few studies have focused on Native Americans. The study purpose was to determine the rate and risk factors for cesarean delivery in a Native American population. METHODS: We used a case-control design nested within a cohort of Native American live births, > or = 35 weeks of gestation (n = 789), occurring at an Indian Health Service hospital during 1996-1999. Data were abstracted from the labor and delivery logbook, the hospital's primary source of birth certificate data. Univariate and multivariate analyses examined demographic, prenatal, obstetric, intrapartum, and fetal factors associated with cesarean versus vaginal delivery. RESULTS: The total cesarean rate was 9.6 percent (95% CI 7.2-12.0). Nulliparity, a medical diagnosis, malpresentation, induction, labor length > 12.1 hours, arrested labor, fetal distress, meconium, and gestations < 37 weeks were each significantly associated with cesarean delivery in unadjusted analyses. The final multivariate model included a significant interaction between induction and arrested labor (p < 0.001); the effect of arrested labor was far greater among induced (OR 161.9) than noninduced (OR 6.0) labors. Other factors significantly associated with cesarean delivery in the final logistic model were an obstetrician labor attendant (OR 2.4; p = 0.02) and presence of meconium (OR 2.3; p = 0.03). CONCLUSIONS: Despite a higher prevalence of medical risk factors for cesarean delivery, the rate at this hospital was well below New Mexico (16.4%, all races) and national (21.2%, all races) cesarean rates for 1998. Medical and practice-related factors were the only observed independent correlates of cesarean delivery. Implementation of institutional and practitioner policies common to the Indian Health Service may reduce cesarean deliveries in other populations.

Anti-smoking socialization beliefs among rural Native American and White parents of young children.

This study assesses similarities and differences in anti-smoking socialization beliefs of White and Native American parents in a low-income, rural population in northeastern Oklahoma. Data are from a population-based, cross-sectional children's environmental health study in which in-home interviews were conducted with 356 parents (56.2% White, 43.8% Native American), primarily mothers, of young children. Approximately 65% of the participants had a high school education or less and over 50% smoked. The Native American participants represented numerous tribes and did not live on reservations. Multivariate logistic regression models were used to examine associations between race/ethnicity, education, smoking status and six anti-smoking socialization beliefs. Results showed that White and Native American parents in this study were very similar in their anti-smoking socialization beliefs, with the one exception that Native American parents were less likely to believe that schools are better than parents in teaching children about the dangers of cigarette smoking. Parental education was significantly associated with the beliefs that all children will try smoking and that forbidding children to smoke will only make them want to smoke more, with less-educated parents more likely to share these beliefs. Findings suggest that interventions to promote anti-smoking socialization beliefs among parents with high school education or less may be important in low-income, rural communities with high smoking rates.

Socioeconomic disparities in intimate partner violence against Native American women: a cross-sectional study.

BACKGROUND: Intimate partner violence (IPV) against women is a global public health problem, yet data on IPV against Native American women are extremely limited. We conducted a cross-sectional study of Native American women to determine prevalence of lifetime and past-year IPV and partner injury; examine IPV in relation to pregnancy; and assess demographic and socioeconomic correlates of past-year IPV. METHODS: Participants were recruited from a tribally-operated clinic serving low-income pregnant and childbearing women in southwest Oklahoma. A self-administered survey was completed by 312 Native American women (96% response rate) attending the clinic from June through August 1997. Lifetime and past-year IPV were measured using modified 18-item Conflict Tactics Scales. A socioeconomic index was created based on partner's education, public assistance receipt, and poverty level. RESULTS: More than half (58.7%) of participants reported lifetime physical and/or sexual IPV; 39.1% experienced severe physical IPV; 12.2% reported partner-forced sexual activity; and 40.1% reported lifetime partner-perpetrated injuries. A total of 273 women had a spouse or boyfriend during the previous 12 months (although all participants were Native American, 59.0% of partners were non-Native). Among these women, past-year prevalence was 30.1% for physical and/or sexual IPV; 15.8% for severe physical IPV; 3.3% for forced partner-perpetrated sexual activity; and 16.4% for intimate partner injury. Reported IPV prevalence during pregnancy was 9.3%. Pregnancy was not associated with past-year IPV (odds ratio = 0.9). Past-year IPV prevalence was 42.8% among women scoring low on the socioeconomic index, compared with 10.1% among the reference group. After adjusting for age, relationship status, and household size, low socioeconomic index remained strongly associated with past-year IPV (odds ratio = 5.0; 95% confidence interval: 2.4, 10.7). CONCLUSIONS: Native American women in our sample experienced exceptionally high rates of lifetime and past-year IPV. Additionally, within this low-income sample, there was strong evidence of socioeconomic variability in IPV. Further research should determine prevalence of IPV against Native American women from diverse tribes and regions, and examine pathways through which socioeconomic disadvantage may increase their IPV risk.

Smoking restrictions in the home and car among rural Native American and white families with young children.

BACKGROUND: This paper examines the prevalence of household and car smoking restrictions, factors associated with these restrictions, and children's exposure to secondhand smoke in homes with varying levels of household smoking restrictions in rural Native American and White families. METHODS: In-person interviews were conducted with 380 rural, low-income Native American and White parents or guardians who were the primary caregivers of children aged 1-6 in northeastern Oklahoma. RESULTS: Prevalence of complete smoking bans was 49.1% in Native American homes and 42.7% in White homes. Car smoking bans were less common, with 34.9% of Native American and 39.6% of White caregivers reporting complete bans. Among nonsmoking households, the proportion of friends who smoked was associated with both car and home smoking bans. Race and education of the caregivers were also associated with car smoking bans in homes with no adult smokers. Among smokers, cigarettes smoked per day, quit attempts within the past year, and the strong belief that secondhand smoke harmed children and babies were related to household smoking bans, whereas cigarettes smoked per day and the proportion of friends who smoked were related to car smoking bans. CONCLUSIONS: Despite the relatively low prevalence of smoking bans in our population, factors associated with household and car smoking bans were similar to those found in the general population.

Lead sources, behaviors, and socioeconomic factors in relation to blood lead of native american and white children: a community-based assessment of a former mining area.

Lead poisoning prevention requires knowledge of lead sources and of appropriate residential lead standards. Data are severely lacking on lead sources for Native American children, many of whom live in rural areas. Further, the relation of mining waste to blood lead concentrations (BPbs) of rural children is controversial. In collaboration with the eight tribes of northeastern Oklahoma, we assessed lead sources and their effects on BPbs for rural Native American and White children living in a former mining region. Venous blood lead, residential environmental (soil, dust, paint, water), and caregiver interview (e.g., hand-to-mouth behaviors, socioeconomic conditions) data were obtained from a representative sample of 245 children 1-6 years of age. BPbs ranged from 1 to 24 microg/dL. There were no ethnic differences in BPbs (p= 0.48) nor any patterns of excess lead sources for Native American or White children. Multiple linear regression analyses indicated that mean soil lead, mean floor lead loading, mouthing behaviors, caregivers' education, and residence in former mining towns were all strongly associated with BPbs. Logistic regression results showed mean floor dust lead loading greater than or equal to 10.1 microg/ft(2) (odds ratio [OR], 11.4; 95% confidence interval [CI], 3.5-37.3), and yard soil lead >165.3 mg/kg (OR, 4.1; CI, 1.3-12.4) were independently associated with BPbs greater than or equal to 10 microg/dL. We also found strong interactions between soil lead and poverty (p= 0.005), and dust and soil sources (p= 0.02). Our findings indicate that soil and dust lead derived largely from mining waste pose a health hazard to Native American and White children, and that current residential dust lead standards are insufficient to adequately protect children. Moreover, our finding that poor children are especially vulnerable to lead exposures suggests that residential standards should consider interactions among socioeconomic conditions and lead sources if environmental justice is to be achieved.
