A nationwide population-based study identifying health disparities between American Indians/Alaska Natives and the general populations living in select urban counties

Development and Feasibility Pilot Study of Indigenous Recovery Planning: A Community-Engaged Approach to Addressing Substance Use in a Native Community

Although Native (American Indian and Alaska Native [AI/AN]) populations have high rates of abstinence from alcohol, health problems associated with substance use remain a pressing concern in many AI/AN communities. As part of a longstanding community-based participatory research (CBPR) project involving five years of relationship building and three preliminary studies, our team of academic and community co-researchers developed a culturally grounded intervention to facilitate recovery from substance use disorders among tribal members from a rural AI reservation. Our Indigenous Recovery Planning (IRP) intervention consists of six weekly sessions and aims to provide inroads to existing resources in the community, affirm and enhance Native identity, address culturally relevant risk factors, and build upon strengths. Results from a feasibility pilot study (N = 15) suggest that IRP is feasible to implement and acceptable to the community. Although there was insufficient statistical power to conduct hypothesis testing, there were changes between pretest and posttest scores in the expected directions. Future directions and limitations of this research are discussed.

COVID-19 vaccine hesitancy among American Indian and Alaska native college students: the roles of discrimination, historical trauma, and healthcare system distrust

For American Indians and Alaska Native (AIAN) and other communities of color, experiences with discrimination and historical trauma may contribute to healthcare system distrust and negatively affect health care decisions, including vaccination. A saturated path analysis was conducted to examine the direct and indirect associations of thoughts regarding historical losses (of culture, language, and traditional ways) and AIAN racial discrimination with historical loss associated distress, healthcare system distrust, and COVID-19 vaccine hesitancy among AIAN college students (N = 391). Historical loss thoughts and experiences with racial discrimination were strongly associated with each other, and both were uniquely associated with greater historical loss associated distress. In turn, historical loss associated distress was associated with greater healthcare system distrust, which in turn was associated with greater likelihood of being COVID-19 vaccine hesitant. While further research is needed, the findings suggest that to address health disparities for AIAN people it is necessary to consider how to best overcome healthcare system distrust and factors that contribute to it, including historical trauma and contemporary experiences with discrimination.

Population-based birth cohort study on diabetes in pregnancy and infant hospitalisations in Cree, other First Nations and non-Indigenous communities in Quebec

OBJECTIVES

Diabetes in pregnancy, whether pre-gestational (chronic) or gestational (de novo hyperglycaemia), increases the risk of adverse birth outcomes. It is unclear whether gestational diabetes increases the risk of postnatal morbidity in infants. Cree First Nations in Quebec are at high risk for diabetes in pregnancy. We assessed whether pre-gestational or gestational diabetes may increase infant hospitalisation (an infant morbidity indicator) incidence, and whether this may be related to more frequent infant hospitalisations in Cree and other First Nations in Quebec.

DESIGN

Population-based birth cohort study through administrative health data linkage.

SETTING AND PARTICIPANTS

Singleton infants (≤1 year) born to mothers in Cree (n=5070), other First Nations (9910) and non-Indigenous (48 200) communities in rural Quebec.

RESULTS

Both diabetes in pregnancy and infant hospitalisation rates were much higher comparing Cree (23.7% and 29.0%) and other First Nations (12.4% and 34.1%) to non-Indigenous (5.9% and 15.5%) communities. Compared with non-diabetes, pre-gestational diabetes was associated with an increased risk of any infant hospitalisation to a greater extent in Cree and other First Nations (relative risk (RR) 1.56 (95% CI 1.28 to 1.91)) than non-Indigenous (RR 1.26 (1.15 to 1.39)) communities. Pre-gestational diabetes was associated with increased risks of infant hospitalisation due to diseases of multiple systems in all communities. There were no significant associations between gestational diabetes and risks of infant hospitalisation in all communities. The population attributable risk fraction of infant hospitalisations (overall) for pre-gestational diabetes was 6.2% in Cree, 1.6% in other First Nations and 0.3% in non-Indigenous communities.

CONCLUSIONS

The study is the first to demonstrate that pre-gestational diabetes increases the risk of infant hospitalisation overall and due to diseases of multiple systems, but gestational diabetes does not. High prevalence of pre-gestational diabetes may partly account for the excess infant hospitalisations in Cree and other First Nations communities in Quebec.

Preterm Birth and Metal Mixture Exposure among Pregnant Women from the Navajo Birth Cohort Study

BACKGROUND

Preterm birth (PTB), defined as birth before 37 wk gestation, is associated with hypertension, diabetes, inadequate prenatal care, unemployment or poverty, and metal exposure. Indigenous individuals are more likely to have maternal risk factors associated with PTB compared with other populations in the United States; however, the role of environmental metals on PTB among pregnant Indigenous women remains uncertain. Previous research identified associations between PTB and individual metals, but there is limited investigation on metal mixtures and this birth outcome.

OBJECTIVES

We used a mixtures analysis framework to investigate the association between metal mixtures and PTB among pregnant Indigenous women from the Navajo Birth Cohort Study (NBCS).

METHODS

Maternal urine and blood samples were collected at the time of study enrollment and analyzed for metals by inductively coupled plasma dynamic reaction cell mass spectrometry. Bayesian Profile Regression was used to identify subgroups (clusters) of individuals with similar patterns of coexposure and to model association with PTB.

RESULTS

Results indicated six subgroups of maternal participants with distinct exposure profiles, including one group with low exposure to all metals and one group with total arsenic, cadmium, lead, and uranium concentrations exceeding representative concentrations calculated from the National Health and Nutrition Examination Survey (NHANES). Compared with the reference group (i.e., the lowest exposure subgroup), the subgroup with the highest overall exposure had a relative risk of PTB of 2.9 times (95% credible interval: 1.1, 6.1). Exposures in this subgroup were also higher overall than NHANES median values for women 14-45 years of age.

DISCUSSION

Given the wide range of exposures and elevated PTB risk for the most exposed subgroups in a relatively small study, follow-up investigation is recommended to evaluate associations between metal mixture profiles and other birth outcomes and to test hypothesized mechanisms of action for PTB and oxidative stress caused by environmental metals. https://doi.org/10.1289/EHP10361.

Factors influencing the sex ratio at birth in the United States from a historical perspective

Many of the studies on the sex ratio at birth (SRB) are based on a small number of cases over a short period of time. Taking a multivariate approach to a dataset consisting of nearly 199 million birth records in the United States from 1968 to 2019, we present a detailed analysis of several possible factors that might affect the sex ratio at birth (SRB) and its patterns of variation. We found that race/ethnicity is the variable with the strongest influence on this index. Parental age, birth order and solar radiation also have a bearing on the SRB, albeit only to a moderate degree. The historical evolution of the SRB among Black and American Indian and Alaska Native populations remains unexplained.

Disparities in Perinatal and Emergency Care Receipt Among Women With Perinatal Opioid Use Disorder in Medicaid, 2007 to 2012

OBJECTIVES

This study aimed to better understand receipt of perinatal and emergency care among women with perinatal opioid use disorder (OUD) and explore variation by race/ethnicity.

METHODS

We used 2007-2012 Medicaid Analytic eXtract (MAX) data from all 50 states and the District of Columbia to examine 6,823,471 deliveries for women 18 to 44 years old. Logistic regressions modeled the association between (1) OUD status and receipt of perinatal and emergency care, and (2) receipt of perinatal and emergency care and race/ethnicity, conditional on OUD diagnosis and controlling for patient and county characteristics. We used robust SEs, clustered at the individual level, and included state and year fixed effects.

RESULTS

Women with perinatal OUD were less likely to receive adequate prenatal care (adjusted odds ratio [aOR], 0.45; 95% confidence interval [CI], 0.44-0.46) and attend the postpartum visit (aOR, 0.46; 95% CI, 0.45-0.47) and more likely to seek emergency care (aOR, 1.48; 95% CI, 1.45-1.51) than women without perinatal OUD. Among women with perinatal OUD, Black, Hispanic, and American Indian and Alaskan Native (AI/AN) women were less likely to receive adequate prenatal care (aOR, 0.68 [95% CI, 0.64-0.72]; aOR, 0.86 [95% CI, 0.80-0.92]; aOR, 0.71 [95% CI, 0.64-0.79]) and attend the postpartum visit (aOR, 0.85 [95% CI, 0.80-0.91]; aOR, 0.86 [95% CI, 0.80-0.93]; aOR, 0.83 [95% CI, 0.73-0.94]) relative to non-Hispanic White women. Black and AI/AN women were also more likely to receive emergency care (aOR, 1.13 [95% CI, 1.05-1.20]; aOR, 1.12 [95% CI, 1.00-1.26]).

CONCLUSIONS

Our findings suggest that women with perinatal OUD, in particular Black, Hispanic, and AI/AN women, may be missing opportunities for preventive care and comprehensive management of their physical and behavioral health during pregnancy.

What Kinds of Support are Alaska Native Youth and Young Adults Reporting? An Examination of Types, Quantities, Sources, and Frequencies of Support

American Indian and Alaska Native (AI/AN) youth, particularly males, experience disproportionately high rates of suicide compared to other young people in the United States. Therefore, enacting suicide prevention efforts for AI/AN youth is especially important. Since research shows that strengthening social, cultural, and emotional support can reduce suicide risk, many recent prevention efforts focus on these strategies. Yet, to reinforce and to extend the positive impact of these strategies for suicide risk reduction, we argue it is useful to identify baseline levels and other features of already-existing support. Toward this end, we describe the types (i.e., category), quantities (i.e., distribution and average number), sources (i.e., from whom), and frequencies (i.e., how often) of social support that AN young people report receiving, and we examine if these "support profiles" differ by age and sex. We use survey data from 165 ANs under age 30, collected as part of a participatory intervention study focused on Promoting Community Conversations About Research to End Suicide (PC CARES). We find that: 1) most ANs reported receiving nearly all supports, 2) compared with females, males reported receiving fewer supports on average, 3) family was the most selected support source, followed by close friends and service providers, and 4) family (e.g., parents, siblings, and grandparents) provided support regularly (i.e., monthly or more). Though our findings may suggest fruitful avenues for interventions targeted toward AN males, we discuss these findings in relation to the gendered nature of suicide prevention and assessment.

Structural and Social Determinants of Inequitable Environmental Exposures in the United States

American Indian (AI)/Alaskan Natives, African Americans, and Latino Americans have disproportionally high exposure to harmful environmental conditions as a consequence of unjust laws and policies, systemic racism, residential segregation, and discrimination. In this review, we draw connections between historical policies and social movements in the United States' history that have been rooted in racism and classism, leading to social isolation and marginalization of AIs, African Americans, and Latino Americans. We then discuss the structural factors that stem from the aforementioned inequities and that contribute to the inequitable distribution of environmental hazards.

Native opportunities to stop hypertension: study protocol for a randomized controlled trial among urban American Indian and Alaska Native adults with hypertension

Introduction

American Indian and Alaska Native (AI/AN) adults experience disproportionate cardiovascular disease (CVD) morbidity and mortality compared to other races, which may be partly attributable to higher burden of hypertension (HTN). Dietary Approaches to Stop Hypertension (DASH) is a high-impact therapeutic dietary intervention for primary and secondary prevention of CVD that can contribute to significant decreases in systolic blood pressure (BP). However, DASH-based interventions have not been tested with AI/AN adults, and unique social determinants of health warrant independent trials. This study will assess the effectiveness of a DASH-based intervention, called Native Opportunities to Stop Hypertension (NOSH), on systolic BP among AI/AN adults in three urban clinics.

Methods

NOSH is a randomized controlled trial to test the effectiveness of an adapted DASH intervention compared to a control condition. Participants will be aged ≥18 years old, self-identify as AI/AN, have physician-diagnosed HTN, and have elevated systolic BP (≥ 130 mmHg). The intervention includes eight weekly, tailored telenutrition counseling sessions with a registered dietitian on DASH eating goals. Intervention participants will be provided $30 weekly and will be encouraged to purchase DASH-aligned foods. Participants in the control group will receive printed educational materials with general information about a low-sodium diet and eight weekly $30 grocery orders. All participants will complete assessments at baseline, after the 8-week intervention, and again 12 weeks post-baseline. A sub-sample of intervention participants will complete an extended support pilot study with assessments at 6- and 9-months post-baseline. The primary outcome is systolic BP. Secondary outcomes include modifiable CVD risk factors, heart disease and stroke risk scores, and dietary intake.

Discussion

NOSH is among the first randomized controlled trials to test the impact of a diet-based intervention on HTN among urban AI/AN adults. If effective, NOSH has the potential to inform clinical strategies to reduce BP among AI/AN adults.

Racial and Ethnic Equity in Care for Hypertension and Diabetes in an Urban Indian Health Organization

Approximately 70% of American Indian/Alaska Native (AI/AN) individuals reside in urban areas. Urban Indian Health Organizations (UIHOs) provide culturally engaged primary care for AI/AN patients and members of other racial and ethnic groups who have experienced disparities in diabetes and hypertension care, and are commonly affected by social and economic barriers to care. We assessed whether disparities were present between the racial and ethnic groups served by the largest UIHO in the USA. We developed retrospective cohorts of patients with hypertension or diabetes receiving primary care from this UIHO, measuring differences between AI/AN, Spanish-preferring Latinx, English-preferring Latinx, Black, and White patients in mean systolic blood pressure (SBP) and mean hemoglobin A1c (A1c) as primary outcomes. To assess processes of care, we also compared visit intensity, missed visits, and medication treatment intensity in regression models adjusted for sociodemographic and clinical characteristics. For hypertension (n = 2148), adjusted mean SBP ranged from 135.8 mm Hg among Whites to 141.3 mm Hg among Blacks (p = 0.06). For diabetes (n = 1211), adjusted A1c ranged from 7.7% among English-preferring Latinx to 8.7% among Blacks (p = 0.38). Care processes for both hypertension and diabetes varied across groups. No group consistently received lower-quality care. This UIHO provided care of comparable quality for hypertension and diabetes among urban-dwelling AI/ANs and members of other racial, ethnic, and language preference groups. Systematic assessments of care quality in UIHOs may help demonstrate the importance of their role in providing care and improve the quality of care.

Knowing Who You Are (Becoming): Effects of a university-based elder-led cultural identity program on Alaska Native students' identity development, cultural strengths, sense of community, and behavioral health

In part due to cultural loss and identity disruption over many generations from colonial and neocolonial forces, significant emotional/behavioral health disparities exist among Alaska Native (AN) people. Such forces are apparent in higher education, where many AN students feel othered and are more likely to withdraw without a degree than their nonnative counterparts. A strong cultural identity has been found to buffer psychosocial difficulties. The AN Cultural Identity Project (CIP) was developed from the best available scientific literature, local data from AN students, and traditional wisdom from Elders to support cultural identity development. This 8-week Elder-led program incorporated storytelling, experiential learning, connection, exploration, and sharing of identity and cultural strengths to help students remain grounded in their cultures across settings in the hopes of improving emotional/behavioral health outcomes. Through a stepped-wedge design randomized controlled trial, we examined the impact of CIP on cultural identity, cultural strengths, sense of community, and emotional/behavioral health across two cohorts of 44 AN students who ranged in age from 18 to 54 years. On average, students attended 75% of the program. The program had positive impacts on students' cultural identity development, endorsement of cultural strengths, sense of community with AN people at the university, and overall emotional/behavioral health. While gains in some outcomes were sustained over time, others were not, suggesting the potential benefits of a lengthened program. As the first program of its kind directed at AN university students of diverse cultural groups in urban settings, CIP shows promise for supporting emotional/behavioral health through cultural identity development.

The Culture is Prevention Project: measuring cultural connectedness and providing evidence that culture is a social determinant of health for Native Americans

BACKGROUND

It is important for non-Native persons to understand that the meaning of culture to Native American/Indigenous Peoples is not about esteem, taste or music but rather is described as a cognitive map on how to be. Native American/Indigenous culture can be thought of as all the things and ways in which Native/Indigenous people understand who they are, where they come from and how they are to interact with others. Hundreds of years across many generations have taught that culture-based activities and interventions improve Native/Indigenous health and wellbeing. We explore if increased Native American culture/cultural connectedness is associated with better mental health/well-being and physical health.

METHODS

We analyzed data from a two-phased study (N = 259 and N = 102) of 361 urban Native Americans in California (2018-2021). The 29 items validated Cultural Connectedness Scale-California (CCS-CA) measured Native culture/cultural connectedness. Mental health/well-being and physical health were assessed using the: modified Herth Hope Index (mHHI), Satisfaction with Life (SWL), Center for Epidemiologic Studies Depression Scale-Revised (CESD-R-10), Substance Abuse (CAGE-AID), and Health Related Quality of Life (HRQOL). We conducted Pearson correlations and stepwise regression analyses with CCS-CA as the independent (predictor) variable to explore our main research questions: 1) Is increased Native American/Indigenous culture associated with: 1) better mental health/well-being; and 2) better physical health?

RESULTS

Increased Native/Indigenous culture (CCS-CA scores) is significantly associated with better mental health/well-being (mHHI, p < .001) and satisfaction with life (SWL, p < .001) predicts good physical health days (HRQOL, p < .001). Increased connection to Native American/Indigenous culture (CCS-CA scores) is significantly associated with decreased risk for depression (CESD-R-10, p < .0) and substance abuse and (CAGE-AID, p < .07). Significant results for culture as protective against risk for substance abuse (CAGE-AID) was most likely affected (p value approaching significance) due to an error in language on the measure (i.e., created double negative).

CONCLUSIONS

Native American/Indigenous culture is a predictor of improved outcomes for mental health/well-being and physical healthy days. Native culture is an important social determinant of health. We add to the evidence that Native/Indigenous culture (i.e., cultural connectedness) be considered an important intervention objective and health-related outcome measure.

Food insecurity, sleep, and cardiometabolic risks in urban American Indian/Alaska Native youth

OBJECTIVES

Food insecurity contributes to racial/ethnic disparities in health. This is the first study to examine associations among food insecurity, sleep, and cardiometabolic outcomes in urban American Indian/Alaska Native (AI/AN) youth.

DESIGN

Participants were 142 urban AI/AN youth (mean age = 14 years, 58% female). Food insecurity and self-reported sleep disturbance were measured using validated surveys. A multi-dimensional sleep health composite was derived using questionnaires (ie, satisfaction, alertness) and actigraphy-derived indices (ie, duration, efficiency, regularity, timing). Cardiometabolic measures included body mass index, blood pressure, glycosylated hemoglobin, waist circumference, cholesterol, and triglycerides. Covariates were sex, age, and single-parent household.

RESULTS

Greater food insecurity was significantly associated with greater body mass index (b = 0.12, p = .015), higher systolic blood pressure (b = 0.93, p = .03), and greater sleep disturbance (b = 1.49, p < .001), and marginally associated with lower sleep health composite scores (b = -0.09, p = .08). There was a significant indirect path from greater food insecurity to greater waist circumference through poorer sleep health (0.11, 95% bootstrapping CI: [0.01, 0.30]).

CONCLUSION

Food insecurity is an important correlate of sleep and cardiometabolic health among urban AI/AN youth and should be addressed to reduce emerging health risks during this important developmental period. Policies to reduce food insecurity and increase access to healthy foods as well as sleep interventions for these youth could help, as preliminary findings suggest that sleep health may mediate the negative impact of food insecurity on cardiometabolic risks.

Recovery from alcohol among urban Alaska Native and American Indian people

Alaska Native and American Indian (ANAI) people experience dramatic alcohol-related health disparities compared to the general US population. Although the majority of ANAI people reside in urban settings (>70%), data are sparse on alcohol abstinence among urban ANAI people with alcohol use disorder (AUD). We conducted a qualitative study using a phenomenological approach to examine the experiences of 20 urban ANAI adults recovering from AUD. Participants' narratives had their own unique dimensions but shared a clear, interrelated trajectory of pre-alcohol recovery, a turning point, and ongoing alcohol recovery. All participants reported a combination of external and internal motivation to stop using alcohol.

Sleep Problems Mediate the Relationship Between Psychosocial Stress and Pain Facilitation in Native Americans: A Structural Equation Modeling Analysis from the Oklahoma Study of Native American Pain Risk

BACKGROUND

Native Americans (NAs) are more likely to experience chronic pain than non-Hispanic Whites (NHWs); however, the proximate causes predisposing NAs to chronic pain remain elusive. Likely due to centuries of adversity, discrimination, and marginalization, NAs report greater psychological stress than NHWs, which may place them at risk for sleep problems, a well-established risk factor for chronic pain onset.

PURPOSE

This study examined the effects of psychological stress and sleep problems on subjective and physiological measures of pain processing in NAs and NHWs.

METHODS

Structural equation modeling was used to determine whether ethnicity (NA or NHW) was associated with psychological stress or sleep problems and whether these variables were related to conditioned pain modulation of pain perception (CPM-pain) and the nociceptive flexion reflex (CPM-NFR), temporal summation of pain (TS-pain) and NFR (TS-NFR), and pain tolerance in a sample of 302 (153 NAs) pain-free participants.

RESULTS

NAs experienced more psychological stress (Estimate = 0.027, p = .009) and sleep problems (Estimate = 1.375, p = .015) than NHWs. When controlling for age, sex, physical activity, BMI, and general health, NA ethnicity was no longer related to greater sleep problems. Psychological stress was also related to sleep problems (Estimate = 30.173, p = <.001) and psychological stress promoted sleep problems in NAs (indirect effect = 0.802, p = .014). In turn, sleep problems were associated with greater TS-pain (Estimate = 0.714, p = .004), but not other pain measures.

CONCLUSIONS

Sleep problems may contribute to chronic pain risk by facilitating pain perception without affecting facilitation of spinal neurons or endogenous inhibition of nociceptive processes. Since psychological stress promoted pain facilitation via enhanced sleep problems, efforts to reduce psychological stress and sleep problems among NAs may improve health outcomes.

Emergency Department Use by Women Experiencing Homelessness in Los Angeles, California, USA

Background:

This article reports on the use of hospital Emergency Departments (EDs) in women experiencing homelessness in Los Angeles, California. Women 18 years of age or older were recruited from homeless day centers in Los Angeles to participate in this study.

Materials and Methods:

A self-report questionnaire on health status, demographics, and emergency service use was completed by study participants.

Results:

In this study of women experiencing homelessness, 64% utilized the ED within the past year. The mean number of ED use was 3.63 (range 0–20) visits in the past year. Higher frequency visits were significantly associated with several mental health conditions (p = 0.016), physical disability (p = 0.001), and traumatic brain injury (p = 0.013).

Conclusions:

The physical and psychological impacts of the homelessness experience can be enormous, affecting the homeless individually and collectively. Study findings may help to understand how to improve services that support and meet the needs of women experiencing homelessness such as patient and family-centered care and trauma-informed care in the ED.

Evaluating vaccination coverage and timeliness in American Indian/Alaska Native and non-Hispanic White children using state immunization information system data, 2015-2017

Comprehensive estimates of vaccination coverage and timeliness of vaccine receipt among American Indian/Alaska Native (AI/AN) children in the United States are lacking. This study’s objectives were to quantify vaccination coverage and timeliness, as well as the proportion of children with specific undervaccination patterns, among AI/AN and non-Hispanic White (NHW) children ages 0–24 months in Montana, a large and primarily rural U.S. state. Data from Montana’s immunization information system (IIS) for children born 2015–2017 were used to calculate days undervaccinated for all doses of seven recommended vaccine series. After stratifying by race/ethnicity, up-to-date coverage at key milestone ages and the proportion of children demonstrating specific patterns of undervaccination were reported. Among n = 3,630 AI/AN children, only 23.1% received all recommended vaccine doses on-time (i.e., zero days undervaccinated), compared to 40.4% of n = 18,022 NHW children (chi-square p < 0.001). A greater proportion of AI/AN children were delayed at each milestone age, resulting in lower overall combined 7-vaccine series completion, by age 24 months (AI/AN: 56.6%, NHW: 64.3%, chi-square p < 0.001). As compared with NHW children, a higher proportion of AI/AN children had undervaccination patterns suggestive of structural barriers to accessing immunization services and delayed starts to vaccination. More than three out of four AI/AN children experienced delays in vaccination or were missing doses needed to complete recommended vaccine series. Interventions to ensure on-time initiation of vaccine series at age 2 months, as well initiatives to encourage completion of multi-dose vaccine series, are needed to reduce immunization disparities and increase vaccination coverage among AI/AN children in Montana.

Substance and Behavioral Addictions among American Indian and Alaska Native Populations

OBJECTIVE

This paper examines substance and behavioral addictions among American Indian and Alaska Natives (AIAN) to identify the structural and psychosocial risk and cultural protective factors that are associated with substance use and behavioral addictions.

METHODS

Five databases were used to search for peer reviewed articles through December 2021 that examined substance and behavioral addictions among AIANs.

RESULTS

The literature search identified 69 articles. Numerous risk factors (i.e., life stressors, severe trauma, family history of alcohol use) and protective factors (i.e., ethnic identity, family support) influence multiple substance (i.e., commercial tobacco, alcohol, opioid, stimulants) and behavioral (e.g., gambling) addictions.

CONCLUSIONS

There is a dearth of research on behavioral addictions among AIANs. Unique risk factors in AIAN communities such as historical trauma and socioeconomic challenges have interfered with traditional cultural resilience factors and have increased the risk of behavioral addictions. Future research on resilience factors and effective prevention and treatment interventions could help AIANs avoid behavioral addictions.

An interview-based evaluation of an Indigenous traditional spirituality program at an urban American Indian health clinic

American Indians suffer from disproportionately high rates of mental health problems. Professional therapies may not meet the specific mental health needs of American Indians, owing to cultural mismatch and long histories of political disempowerment. Instead, Indigenous traditional spiritual practices are often promoted as alternative sources of health and help in these communities. In response to a community needs assessment, we developed a 12-week traditional spirituality curriculum in partnership with the urban American Indian health clinic in Detroit. Centered on the sweat lodge ceremony, the program was pilot tested with 10 community members. Semi-structured interviews were conducted with nine participants following the program. Based on our analyses, all participants endorsed responses within two overarching themes: impact on personal well-being, and suggestions for improvement reflecting their desire for an ongoing program. Participant responses about the program's impact comprised four themes: (1) improved psychological and spiritual well-being, (2) community benefit, (3) increase in cultural knowledge, and (4) a desire for further learning and sharing. Participant responses about their desire for an ongoing program also comprised four themes: (1) drop-in classes may be more practical as regular attendance was difficult for some, (2) future classes should include more areas of knowledge, (3) the program could be expanded to include more knowledge-holders and perspectives, and (4) the program should include a progression of classes to accommodate more diversity. Overall, participants reported benefit from participation in Indigenous spiritual practices; however, the program can be improved by further adapting the curriculum to the sometimes-challenging lives of its participants.

Design and Methods of a Participatory Healthy Eating Intervention for Indigenous Children: The FRESH Study

Objective

To increase vegetable and fruit intake, reduce body mass index (BMI), and improve parental blood pressure among American Indian families.

Design

Randomized, wait-list controlled trial testing a multi-level (environmental, community, family, and individual) multi-component intervention with data collection at baseline and 6 months post-intervention.

Setting

Tribally owned and operated Early Childhood Education (ECE) programs in the Osage Nation in Oklahoma.

Participants

American Indian families (at least one adult and one child in a ECE program). A sample size of 168 per group will provide power to detect differences in fruit and vegetable intake.

Intervention

The 6-month intervention consisted of a (1) ECE-based nutrition and gardening curriculum; (2) nutrition education and food sovereignty curriculum for adults; and (3) ECE program menu modifications.

Main Outcome Measures

The primary outcome is increase in fruit and vegetable intake, assessed with a 24-h recall for adults and plate weight assessments for children. Secondary outcomes included objective measures of BMI among adults and children and blood pressure among adults.

American Indian Behavioral Health Treatment Preferences as Perceived by Urban Indian Health Program Providers

Behavioral health services specifically targeted for ethnoracial clients are typically tailored to the specific needs and preferences of these populations; however, little research has been done with American Indian clients specifically. To better understand how clinicians handle provision of treatment to this population, we interviewed 28 behavioral health staff at six Urban Indian Health Programs in the United States and conducted focus groups with 23 staff at five such programs. Thematic analysis of transcripts from these interviews and focus groups suggests that these staff attempt to blend and tailor empirically supported treatments with American Indian cultural values and practices where possible. Simultaneously, staff try to honor the client's specific preferences and needs and to encourage clients to seek cultural practices and connection outside of the therapy room. In so doing staff members were acutely aware of the limitations of the evidence base and the lack of research with American Indian clients.

Vaginal microbiota of American Indian women and associations with measures of psychosocial stress

Molecular-bacterial vaginosis (BV) is characterized by low levels of vaginal Lactobacillus species and is associated with higher risk of sexually transmitted infections (STI). Perceived psychosocial stress is associated with increased severity and persistence of infections, including STIs. American Indians have the highest rates of stress and high rates of STIs. The prevalence of molecular-BV among American Indian women is unknown. We sought to evaluate measures of psychosocial stress, such as historic loss (a multigenerational factor involving slavery, forced removal from one's land, legally ratified race-based segregation, and contemporary discrimination) and their association with the vaginal microbiota and specific metabolites associated with BV, in 70 Northwestern Plains American Indian women. Demographics, perceived psychosocial stressors, sexual practices, and known BV risk factors were assessed using a modified version of the American Indian Service Utilization, Psychiatric Epidemiology, Risk and Protective Factors Project survey. Self-collected mid-vaginal swabs were profiled for bacterial composition by 16S rRNA gene amplicon sequencing and metabolites quantified by targeted liquid-chromatography mass spectrometry. Sixty-six percent of the participants were classified as having molecular-BV, with the rest being either dominated by L. crispatus (10%) or L. iners (24%). High levels of lifetime trauma were associated with higher odds of having molecular-BV (adjusted Odds Ratio (aOR): 2.5, 95% Credible Interval (CrI): 1.1-5.3). Measures of psychosocial stress, including historic loss and historic loss associated symptoms, were significantly associated with lifestyle and behavioral practices. Higher scores of lifetime trauma were associated with increased concentrations of spermine (aFC: 3.3, 95% CrI: 1.2-9.2). Historic loss associated symptoms and biogenic amines were the major correlates of molecular-BV. Historical loss associated symptoms and lifetime trauma are potentially important underlying factors associated with BV.

Determinants of Relapse and Opportunities for Growth: Perspectives on Substance Use among American Indian Community Members

Resulting from generations of historical oppression and systemic racism, American Indian and Alaska Native (AI/AN) communities experience serious health disparities associated with substance use disorders (SUDs). As part of a longstanding community-based participatory research intervention development project, our partnership of academic and community co-researchers conducted seven focus groups (N = 35) to understand community stakeholders' perspectives on substance use, relapse, and recovery on a rural AI reservation. Participants included cultural leaders (n = 10), SUD treatment providers (n = 5), people with SUD (n = 10), and affected family members (n = 10). Cultural leaders viewed relapse as symptomatic of historical oppression, whereas other stakeholder groups attributed relapse to individual and interpersonal risk factors such as peer influence, lack of family support, and traumatic stress. All participant groups recognized relapse as a normative aspect of recovering from SUD that presents new opportunities for learning and growth. Specifically, regaining humility, learning to ask for help, recognizing one's triggers, and strengthening commitment to change were identified as learning outcomes for people with SUD. For family members, relapse provided the opportunity to practice forgiveness and compassion, two important cultural values. All groups emphasized the importance of grounding interventions in cultural values and traditions.

Belief in the myth of an American Indian/Alaska Native biological vulnerability to alcohol problems among reservation-dwelling participants with a substance use problem

BACKGROUND

Belief in the myth of an American Indian/Alaska Native (AIAN)-specific biological vulnerability (BV) to alcohol problems is associated with worse alcohol outcomes among AIAN college students who drink, despite also being associated with greater attempts to reduce drinking. This study examined the association of belief in a BV with alcohol use among reservation-dwelling AI adults with a substance use problem.

METHODS

Participants (n = 141) who drank alcohol in the past 90 days were selected from a larger AI sample who self-identified as having a substance use problem. Moderated-mediation analyses examined whether belief in a BV was positively associated with alcohol- and substance use-related consequences and whether self-efficacy and craving mediated the association of belief in a BV with alcohol use.

RESULTS

Among participants who reported using alcohol but not hard drugs (e.g., methamphetamine, opioids), greater belief in a BV was associated with more drinking days, which in turn was associated with greater alcohol-related consequences. Among participants who used alcohol only, belief in a BV was also significantly associated with greater craving, and in turn with more drinking days. Among individuals who used both alcohol and hard drugs, greater belief in a BV was associated with fewer drinking days, but was not significantly associated with substance use-related consequences. No association was found between belief in a BV and self-efficacy to avoid alcohol or drug use.

CONCLUSIONS

Among individuals who use only alcohol, belief in a BV may contribute to more drinking days and greater alcohol-related consequences through its association with greater craving. This study provides further evidence of the potential harm of internalizing the belief that being AIAN contributes to the risk for alcohol problems, a notion that lacks scientific evidence despite decades of research. The findings highlight the importance of combating societal myths regarding AIAN peoples and the internalization of these stereotypes.

A Framework for the Adaptation of Positive Psychological Interventions to North American Indigenous Populations

Positive psychology research has led to the development of brief interventions designed to promote positive emotions: positive psychological interventions (PPIs). Randomized controlled trials examining PPIs have found them to be effective in increasing well-being and decreasing depressive symptoms. PPIs have been studied in samples consisting primarily of White Americans; however, PPIs may be useful for members of North American Indigenous groups. PPIs align well with Indigenous views on health, which tend to be strengths-based, holistic, and encompassing the whole body (including the medicine wheel's four dimensions of spirit, mind, heart, and body). This paper provides a framework for the adaptation of PPIs for Indigenous communities and a review of preliminary data on the relationships between positive psychological characteristics and health outcomes including substance use. Implications include the potential widespread impact of culturally adapted PPIs given their alignment with Indigenous thoughts on health and relative ease of administration.

Pre-pregnancy and Prenatal Alcohol use Among American Indian and Alaska Native and Non-Hispanic White Women: Findings from PRAMS in Five States

INTRODUCTION

Estimates of prenatal alcohol use among American Indian and Alaska Native (AI/AN) women are limited. This study sought to characterize pre-pregnancy and prenatal alcohol use among AI/AN women in the Pregnancy Risk Assessment Monitoring System (PRAMS) dataset, evaluate variation in alcohol use by state and rural/urban residence, and evaluate associations between potential risk factors and prenatal alcohol use among AI/AN and non-Hispanic white (NHW) women.

METHODS

We pooled PRAMS data from five states (Alaska, New Mexico, Oklahoma, South Dakota and Washington) from 2015 to 2017. We estimated the prevalence of pre-pregnancy and pregnancy risk factors, and alcohol use by race and examined alcohol use by state and rural/urban residence among AI/AN women. We conducted bivariate and multivariable logistic regression modelling to estimate the association between each risk factor of interest and the odds of prenatal alcohol use for AI/AN and NHW women.

RESULTS

AI/AN women were less likely to report pre-pregnancy alcohol use compared to NHW women (56% vs. 76%, p < 0.0001). Among women who reported drinking pre-pregnancy, AI/AN women were more likely than NHW women to report drinking 1 or more drinks during pregnancy (4.3% vs. 2.4, p = 0.0049). For AI/AN women, older age and experiencing homelessness (aOR = 2.76; 95% CI 1.16-6.55) increased odds of prenatal alcohol use. For NHW women, having a college education (aOR = 4.06; 95% CI 1.19-13.88) and urban residence (aOR = 1.88; 95% CI 1.40-2.53) increased odds of prenatal alcohol use.

CONCLUSIONS

Factors associated with prenatal alcohol use differ between AI/AN women and NHW women, suggesting the need for tailored interventions.

Unveiling an 'invisible population': health, substance use, sexual behavior, culture, and discrimination among urban American Indian/Alaska Native adolescents in California

Objectives: There are limited public health data on urban American Indian/Alaska Native (AI/AN) populations, particularly adolescents. The current study attempted to address gaps by providing descriptive information on experiences of urban AI/AN adolescents across northern, central, and southern California.Design: We describe demographics and several behavioral health and cultural domains, including: alcohol and other drug (AOD) use, risky sexual behavior, mental and physical health, discrimination experiences, involvement in traditional practices, and cultural pride and belonging. We recruited 185 urban AI/AN adolescents across northern, central, and southern California from 2014 to 2017 who completed a baseline survey as part of a randomized controlled intervention trial.Results: Average age was 15.6 years; 51% female; 59% of adolescents that indicated AI/AN descent also endorsed another race or ethnicity. Rates of AOD use in this urban AI/AN sample were similar to rates for Monitoring the Future. About one-third of adolescents reported ever having sexual intercourse, with 15% reporting using alcohol or drugs before sex. Most reported good mental and physical health. Most urban AI/AN adolescents participated in traditional practices, such as attending Pow Wows and learning their tribal history. Adolescents also reported discrimination experiences, including being a victim of racial slurs and discrimination by law enforcement.Conclusions: This study describes a select sample of California urban AI/AN adolescents across several behavioral health and cultural domains. Although these adolescents reported numerous discrimination experiences and other stressors, findings suggest that this sample of urban AI/AN teens may be particularly resilient with regard to behavioral health.

Sleep Buffers the Effect of Discrimination on Cardiometabolic Allostatic Load in Native Americans: Results from the Oklahoma Study of Native American Pain Risk

OBJECTIVES

Compared to other racial/ethnic groups, Native Americans (NAs) are more likely to develop health conditions associated with allostatic load (stress-related wear-and-tear). Psychosocial factors (i.e., adverse life events, discrimination, psychological distress) often promote stress and may help explain greater allostatic load in NAs. Moreover, previous research suggests sleep may either mediate or moderate the effects of some psychosocial stressors, like discrimination, on allostatic load. The current study investigated the relationship between adverse life events, discrimination, psychological stress, sleep, and cardiometabolic load.

METHODS

Using a sample of 302 healthy, chronic pain-free NAs and non-Hispanic White (NHW) participants, bootstrapped mediation analyses were conducted to determine whether the relationship between NA race/ethnicity and cardiometabolic allostatic load (composite score of body mass index, mean arterial pressure, and heart rate variability) was mediated by psychosocial stressors. Models also assessed whether sleep disturbance served as an additional mediator or a moderator to the effects.

RESULTS

Consistent with prior research, we found that NAs experienced greater discrimination, adverse life events (potentially traumatic events), and cardiometabolic allostatic load than NHWs. Further, discrimination was associated with increased psychological stress for NAs, but this did not explain why NAs experience higher cardiometabolic allostatic load. A moderating effect of sleep on discrimination was found, such that discrimination partially contributed to the relationship between NA race/ethnicity and cardiometabolic allostatic load, but only for participants reporting greater sleep disturbance. Implications These findings highlight that good sleep can buffer the effect of psychosocial stress on cardiometabolic allostatic load in Native Americans.

Identifying Disparities in Health Outcomes and Mortality for American Indian and Alaska Native Populations Using Tribally Disaggregated Vital Statistics and Health Survey Data

Objectives. To determine the impact of disaggregated mortality and health surveillance data on the ability to identify health disparities for American Indian and Alaska Native (AI/AN) subpopulations. Methods. We conducted a systematic review of reporting categories for AI/AN decedents on official death certificates for all 50 US states. Using public data from the 2017-2018 California Health Interview Survey (CHIS), we conducted bivariate and multivariate analyses to assess disparities in health conditions and outcomes for tribally enrolled and non‒tribally enrolled AI/AN persons compared with non-Hispanic Whites. Results. There was no standard for the collection of tribal enrollment data or AI/AN race on death certificates across all 50 states. There were stark differences in the incidence and prevalence of various health risk factors and chronic diseases for the tribally enrolled AI/AN subpopulation, non‒tribally enrolled AI/AN subpopulation, and non-Hispanic White comparison group. Conclusions. The collection of tribal enrollment data in vital statistics and health surveillance systems is necessary to identify and respond to health disparities among AI/AN subpopulations. These efforts must be conducted in partnership with tribal nations and consider Indigenous data sovereignty.

Loneliness and sleep in the American Indian Blackfeet community

BACKGROUND

Sleep is largely understudied in American Indians (AIs), even though sleep is implicated in the chronic diseases which disproportionately affect AI communities.

OBJECTIVE

To investigate relationships between daily self-reported loneliness and sleep as measured with actigraphy.

METHODS

In a sample of 98 Blackfeet adults living on the Blackfeet reservation in Montana, we used Ecological Momentary Assessment and actigraphy over a week-long period to investigate relationships between loneliness and sleep. Loneliness was measured daily using the Short Loneliness Scale and actigraphy was used to measure total sleep time, sleep onset latency (SOL), wake after sleep onset (WASO), and sleep efficiency (SE).

RESULTS

Using a series of generalized linear mixed-effects models controlling for demographic characteristics, anxiety and depressive symptoms, and adverse childhood experiences, we found that those who were lonelier had higher WASO and SOL, and lower SE relative to those who were less lonely. Within-subject effects indicate that participants who were lonelier for a given day relative to their own weekly average had higher WASO that night relative to their own weekly average.

CONCLUSIONS

Our findings provide initial preliminary evidence suggesting that loneliness may be a psychosocial factor which contributes to poor sleep in AI communities.

Maternal Mortality Among American Indian/Alaska Native Women: A Scoping Review

Background: Maternal mortality decreased globally by about 38% between 2000 and 2017, yet, it continues to climb in the United States. Gaping disparities exist in U.S. maternal mortality between white (referent group) and minority women. Despite important and appropriate attention to disparities for black women, almost no attention has been given to American Indian/Alaska Native (AI/AN) women. The purpose of this scoping review is to synthesize available literature concerning AI/AN maternal mortality. Methods: Databases were searched using the terms maternal mortality and pregnancy-related death, each paired with American Indian, Native American, Alaska Native, Inuit, and Indigenous. Criteria (e.g., hemorrhage) were paired with initial search terms. Next, pregnancy-associated death was paired with American Indian, Native American, Alaska Native, Inuit, and Indigenous. Criteria in this category were homicide, suicide, and substance use. Results: The three leading causes of AI/AN pregnancy-related maternal mortality are hemorrhage, cardiomyopathies, and hypertensive disorders of pregnancy. AI/AN maternal mortality data for homicide and suicide consistently include small samples and often categorize AI/AN maternal deaths in an "Other" race/ethnicity, which precludes targeted AI/AN data analysis. No studies that reported AI/AN maternal mortality as a result of substance use were found. Health care characteristics such as quality, access, and location also may influence maternal outcomes and maternal mortality. Conclusions: Despite AI/AN maternal mortality being disproportionately high compared to other racial/ethnic groups, relatively little is known about root causes.

Exploring values among three cultures from a global bioethics perspective

The United Nations Educational, Scientific and Cultural Organisation's (UNESCO) Declaration on Bioethics and Human Rights refers to the importance of cultural diversity and pluralism in ethical discourse and care of humanity. The aim of this meta-narrative review is to identify indigenous ethical values pertaining to the Ojibway (Canada), Xhosa (South Africa), and Mayan (Mexico and Central American) cultures from peer-reviewed sources and cultural review, and to ascertain if there are shared commonalities. Three main themes were identified, namely illness, healing, and health care choices. Illness was described with a more complex and dynamic picture than from the western view, as illness is not considered to be one dimensional. Healing needs to take place on various levels in order to restore a state of equilibrium between the different spheres. Health care choices were also considered from a multi-level perspective. In all three of the indigenous cultures explored, good decision-making is seen to have occurred when choices are informed by commitments to one's moral and ethical responsibilities towards the community, nature, and the spirit world.

Identifying as American Indian/Alaska Native in Urban Areas: Implications for Adolescent Behavioral Health and Well-Being

American Indian and Alaska Native (AI/AN) youth exhibit multiple health disparities, including high rates of alcohol and other drug (AOD) use, violence and delinquency, and mental health problems. Approximately 70% of AI/AN youth reside in urban areas, where negative outcomes on behavioral health and well-being are often high. Identity development may be particularly complex in urban settings, where youth may face more fragmented and lower density AI/AN communities, as well as mixed racial-ethnic ancestry and decreased familiarity with AI/AN lifeways. This study examines racial-ethnic and cultural identity among AI/AN adolescents and associations with behavioral health and well-being by analyzing quantitative data collected from a baseline assessment of 185 AI/AN urban adolescents from California who were part of a substance use intervention study. Adolescents who identified as AI/AN on their survey reported better mental health, less alcohol and marijuana use, lower rates of delinquency, and increased happiness and spiritual health.

The Urban American Indian Traditional Spirituality Program: Promoting Indigenous Spiritual Practices for Health Equity

Beginning in 2009, Detroit's urban American Indian health center entered into a collaborative and participatory partnership with a university research team. The purpose of the partnership was to incorporate Indigenous traditional healing practices into the health and wellness services at this center. Following extensive consultation with stakeholders at the center, we were commissioned by local decision-makers to develop a program tailored for members of the urban American Indian community that would introduce and orient these individuals to meaningful participation in Indigenous traditional spirituality. The Urban American Indian Traditional Spirituality Program is a structured curriculum for American Indian community members that introduces and orients participants to meaningful engagement with sacred practices associated with the sweat lodge ceremony. The signature innovation of this program was the recasting of traditional socialization practices into a structured, didactic curriculum that could initiate an enduring spiritual devotional life for American Indian participants toward improved health and well-being. Created primarily "by Indians, for Indians," the collaboratively designed curriculum draws on cultural strengths and spiritual empowerment to advance health equity for these marginalized populations.

Parenting in 2 worlds: Effects of a culturally grounded parenting intervention for urban American Indians on participant cultural engagement

BACKGROUND

Culturally appropriate, evidence-based prevention programs are seldom available to the growing majority of American Indians (AIs) who now live in cities. Parenting in 2 Worlds (P2W), a culturally grounded parenting intervention, was created to strengthen family functioning and reduce behavioral health risks in urban AI families from diverse tribal backgrounds.

OBJECTIVES

This study reports on the AI cultural engagement of the P2W participants as an outcome of the intervention.

METHOD

Data came from 575 parents of AI children (ages 10-17) in a randomized controlled trial in three Arizona cities. Parents were recruited through urban Indian centers and randomized to P2W or to an informational family health curriculum, Healthy Families in 2 Worlds (HF2W). Both P2W and HF2W consisted of 10 workshops delivered weekly by AI community facilitators. Pretests and posttests measured identification and engagement with traditional AI heritage, culture and practices. Tests of the efficacy of P2W versus HF2W used baseline adjusted regression models using FIML estimation to adjust for attrition, including random effects (site, facilitator), and controlling dosage. Moderated treatment effects by pretest levels of cultural engagement were tested with mean centered interactions.

RESULTS

Compared to parents in HF2W, those in P2W reported significantly larger increases in AI ethnic identity, AI spirituality, and positive mainstream cultural identification. Increases in cultural engagement were significantly larger for P2W participants who were relatively less culturally engaged at pretest.

CONCLUSIONS

Culturally adapted parenting interventions like P2W that effectively build on AI cultural heritage can also promote greater AI cultural identification and involvement. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Racial and Ethnic Disparities in Perinatal Insurance Coverage

Gaps and transitions (disruptions) in perinatal insurance coverage disproportionately affect indigenous, Hispanic, and black non-Hispanic women.

To measure the association between race–ethnicity and insurance status at preconception, delivery, and postpartum and the frequency of insurance gaps and transitions (disruptions) across these time points.

Deaths Associated With Hepatitis C Virus Infection Among Residents in 50 States and the District of Columbia, 2016-2017

BACKGROUND

Mortality associated with hepatitis C virus (HCV) has been well-documented nationally, but an examination across regions and jurisdictions may inform health-care planning.

METHODS

To document HCV-associated deaths sub-nationally, we calculated age-adjusted, HCV-associated death rates and compared death rate ratios (DRRs) for 10 US regions, 50 states, and Washington, D.C., using the national rate and described rate changes between 2016 and 2017 to determine variability. We examined the mean age at HCV-associated death, and rates and proportions by sex, race/ethnicity, and birth year.

RESULTS

In 2017, there were 17 253 HCV-associated deaths, representing 4.13 (95% confidence interval [CI], 4.07-4.20) deaths/100 000 standard population, in a significant, 6.56% rate decline from 4.42 in 2016. Age-adjusted death rates significantly surpassed the US rate for the following jurisdictions: Oklahoma; Washington, D.C.; Oregon; New Mexico; Louisiana; Texas; Colorado; California; Kentucky; Tennessee; Arizona; and Washington (DRRs, 2.87, 2.77, 2.24, 1.62, 1.57, 1.46, 1.36, 1.35, 1.35, 1.35, 1.32, and 1.32, respectively; P < .05). Death rates ranged from a low of 1.60 (95% CI, 1.07-2.29) in Maine to a high of 11.84 (95% CI, 10.82-12.85) in Oklahoma. Death rates were highest among non-Hispanic (non-H) American Indians/Alaska Natives and non-H Blacks, both nationally and regionally. The mean age at death was 61.4 years (range, 56.6 years in West Virginia to 64.1 years in Washington, D.C.), and 78.6% of those who died were born during 1945-1965.

CONCLUSIONS

In 2016-2017, the national HCV-associated mortality declined but rates remained high in the Western and Southern regions and Washington, D.C., and among non-H American Indians/Alaska Natives, non-H Blacks, and Baby Boomers. These data can inform local prevention and control programs to reduce the HCV mortality burden.

Racial and Ethnic Disparities in Patient Experiences in the United States: 4-Year Content Analysis of Twitter

BACKGROUND

Racial and ethnic minority groups often face worse patient experiences compared with the general population, which is directly related to poorer health outcomes within these minority populations. Evaluation of patient experience among racial and ethnic minority groups has been difficult due to lack of representation in traditional health care surveys.

OBJECTIVE

This study aims to assess the feasibility of Twitter for identifying racial and ethnic disparities in patient experience across the United States from 2013 to 2016.

METHODS

In total, 851,973 patient experience tweets with geographic location information from the United States were collected from 2013 to 2016. Patient experience tweets included discussions related to care received in a hospital, urgent care, or any other health institution. Ordinary least squares multiple regression was used to model patient experience sentiment and racial and ethnic groups over the 2013 to 2016 period and in relation to the implementation of the Patient Protection and Affordable Care Act (ACA) in 2014.

RESULTS

Racial and ethnic distribution of users on Twitter was highly correlated with population estimates from the United States Census Bureau's 5-year survey from 2016 (r²=0.99; P<.001). From 2013 to 2016, the average patient experience sentiment was highest for White patients, followed by Asian/Pacific Islander, Hispanic/Latino, and American Indian/Alaska Native patients. A reduction in negative patient experience sentiment on Twitter for all racial and ethnic groups was seen from 2013 to 2016. Twitter users who identified as Hispanic/Latino showed the greatest improvement in patient experience, with a 1.5 times greater increase (P<.001) than Twitter users who identified as White. Twitter users who identified as Black had the highest increase in patient experience postimplementation of the ACA (2014-2016) compared with preimplementation of the ACA (2013), and this change was 2.2 times (P<.001) greater than Twitter users who identified as White.

CONCLUSIONS

The ACA mandated the implementation of the measurement of patient experience of care delivery. Considering that quality assessment of care is required, Twitter may offer the ability to monitor patient experiences across diverse racial and ethnic groups and inform the evaluation of health policies like the ACA.

Comparing vaccination coverage of American Indian children with White children in North Dakota

OBJECTIVES

The objective of this study was to compare immunization rates of American Indian (AI) and White children in North Dakota and identify disparities in immunization rates by race.

STUDY DESIGN

The study design was to assess immunization coverage rates by race using immunization information system (IIS) data.

METHODS

Data from the North Dakota Immunization Information System (NDIIS) for children aged 19-35 months during quarter four of 2014, 2015, 2016, 2017 and 2018 were used to assess and compare immunization coverage rates for AI and White children. NDIIS data were also analyzed for timeliness of vaccine administration, Vaccines for Children (VFC) status, and the number of doses still needed to be considered up to date (UTD) with routinely recommended immunizations.

RESULTS

In quarter four of 2018 (Q4 2018), only 60% of AI children were UTD with the complete 4:3:1:3:3:1:4 vaccine series compared with 74.5% of White children of the same age. Fewer VFC-eligible AI children (59.1%) are UTD than VFC-eligible White children (68.7%). AI children were also more likely to be delayed at each immunization milestone, leading to fewer AI children to be UTD by 19 to 35 months of age.

CONCLUSIONS

This study shows that there is a racial disparity in immunization coverage rates between AI and White children in North Dakota. Public health and private healthcare providers should work to identify and address barriers to vaccination and should implement strategies to increase immunization rates for AI children.

Environmental Risk Perceptions and Community Health: Arsenic, Air Pollution, and Threats to Traditional Values of the Hopi Tribe

American Indian and Alaska Native populations experience chronic disparities in a wide range of health outcomes, many of which are associated with disproportionate exposures to environmental health hazards. In the American Southwest, many indigenous tribes experience challenges in securing access to sustainable and safe sources of drinking water, limiting air pollution emissions on and off tribal lands, and cleaning up hazardous contaminants left over from a legacy of natural resource extraction. To better understand how households perceive the risk of exposure to potential environmental health risks, we conducted six focus groups organized by age and geographic location on the Hopi reservation. Focus group participants (n = 41) were asked to reflect on changes in their natural and manmade environment and how their health might be influenced by any potential changes. By investigating these environmental risk perceptions, we were able to identify arsenic in drinking water and indoor air quality as significant exposures of concern. These risk perceptions were frequently anchored in personal and familial experiences with health problems such as cancer and asthma. Older focus group participants identified ongoing shifts away from tradition and cultural practices as increasing environmental health risks. Similar to other communities economically dependent on the extraction of natural resources, focus group participants described the need for behavioral modifications regarding environmental health risks rather than eliminating the sources of potential health risks entirely. Our results suggest the need for including traditional values and practices in future interventions to reduce environmental health risks.

Motivational interviewing and culture for urban Native American youth (MICUNAY): A randomized controlled trial

To date, few programs that integrate traditional practices with evidence-based practices have been developed, implemented, and evaluated with urban American Indians/Alaska Natives (AI/ANs) using a strong research design. The current study recruited urban AI/AN teens across northern, central, and southern California during 2014-2017 to participate in a randomized controlled trial testing two cultural interventions that addressed alcohol and other drug (AOD) use. Adolescents were 14-18 years old (inclusive), and either verbally self-identified as AI/AN or were identified as AI/AN by a parent or community member. We tested the added benefit of MICUNAY (Motivational Interviewing and Culture for Urban Native American Youth) to a CWG (Community Wellness Gathering). MICUNAY was a group intervention with three workshops that integrated traditional practices with motivational interviewing. CWGs were cultural events held monthly in each city. AI/AN urban adolescents (N = 185) completed a baseline survey, were randomized to MICUNAY + CWG or CWG only, and then completed a three- and six-month follow-up. We compared outcomes on AOD use, spirituality, and cultural identification. Overall, AOD use remained stable over the course of the study, and we did not find significant differences between these two groups over time. It may be that connecting urban AI/AN adolescents to culturally centered activities and resources is protective, which has been shown in other work with this population. Given that little work has been conducted in this area, longer term studies of AOD interventions with urban AI/AN youth throughout the U.S. are suggested to test the potential benefits of culturally centered interventions.

Urban American Indian Adult Participation and Outcomes in Culturally Adapted and Mainstream Alcoholics Anonymous Meetings

Very little is known about American Indian (AI) adults' participation in Alcoholics Anonymous (AA) despite their elevated rates of negative sequelae due to heavy alcohol consumption and alcohol use disorders. This study sought to fill that gap and examined the engagement in AA by urban Southwest AI (S-AI) adult problem drinkers and whether enculturation and acculturation accounted for type of AA attended (mainstream versus culturally adapted AA; CA-AA). Additionally, we compared three and six-month drinking outcomes of urban S-AI adults by type of meeting attended. Sixty-one urban S-AI adults were consented and assessed at baseline, three and six-months. We examined the association between frequency of AA attendance and differences between types of meetings attended regressed on the outcomes of proportion abstinent days and drinks per drinking day. Results indicate that AA attendance is the model approach and assists urban S-AI adults in reducing their drinking. Despite higher engagement among those attending both AA and CA-AA, this did not translate into differential AA-related benefit which speaks to the need for additional research to assist AI adults in effectively reducing their alcohol use.

The role of feature-based discrimination in driving health disparities among Black Americans

Objective: A growing body of research finds that darker skin tone is often associated with poorer physical and mental health in Blacks. However, the psychosocial mechanisms underlying the skin tone-health link remain elusive. The present study seeks to address this knowledge gap by investigating the direct and indirect (through perceived discrimination, socioeconomic status, and self-esteem) effects of skin tone on self-reported physical and mental health.Design: An urban sample of 130 Blacks aged 35 and above completed a self-administered computerized survey as a part of larger cross-sectional study.Results: Self-esteem played a particularly important role in mediating the associations between skin tone and self-reported physical and mental health. This suggests that self-esteem could be a point of intervention to help Blacks with darker skin tone achieve better health.Conclusion: The present study highlights the important role feature-based discrimination plays in determining mental and physical health outcomes among Blacks.

Community Based Participatory Research (CBPR): A Dynamic Process of Health care, Provider Perceptions and American Indian Patients' Resilience

American Indians are disproportionately affected by factors that lead to health disparities, however many Native people demonstrate resilience when faced with health risks. Study objectives were to use a resilience framework to identify wellness strategies among American Indian people and to assess health care provider perceptions of American Indian wellness. Participants included 39 American Indian adults who self-reported resilient change and 22 health care providers who served American Indian patients. Thematic categories across American Indian and health care provider data were identified: 1) relationships inform resilience; 2) prejudice stymies resilience; and 3) place shapes resilience. Results indicated the salience of relationships in demonstrating resilience. Identified challenges and supporters of resilience are discussed.

The associations among sociocultural factors and neuropsychological functioning in older American Indians: The Strong Heart Study

OBJECTIVE

Valid neuropsychological assessment is critical to the accurate diagnosis and effective treatment of diverse populations. American Indians and Alaska Natives experience substantial health disparities relative to the general U.S.

POPULATION

Given the dearth of studies on neuropsychological health in this population, we aimed to characterize neuropsychological performance among older American Indians with respect to age, sex, education, income, and language use.

METHOD

From 2010 to 2014, we recruited 818 American Indians aged 60 and older from the Cerebrovascular Disease and Its Consequences in American Indians Study, who comprised all of the surviving members of a cardiovascular study (Strong Heart Study). This cohort from 11 tribes resided on or near their home reservations in three geographic regions (Northern Plains, Southern Plains, and Southwest). Using a cross-sectional design investigating potential vascular brain injury, we administered a brief, targeted neuropsychological and motor function assessments.

RESULTS

Higher scores on neuropsychological tests were associated with younger age, female sex, more education, higher income, and less Native American language use. Similar associations were found for the motor tests, although men had higher scores on both motor function tests. After accounting for other sociocultural and health factors, age, sex, education, income, and Native American language use all had significant associations to the test scores.

CONCLUSIONS

Our findings may be used to guide research and inform clinical practice. The development of future normative studies for older American Indians will be more culturally appropriate when sociocultural factors are included. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

A storytelling intervention reduces childhood caries risk behaviors among American Indian and Alaska Native mothers in Northern California

OBJECTIVES

To evaluate a storytelling intervention targeting the oral health beliefs, knowledge, and behaviors of AIAN pregnant women and mothers.

METHODS

Fifty-three adult AIAN women from three tribal communities in Northern California participated. The intervention story delivered oral health messaging using a traditional storytelling format. The effect of the intervention on self-reported oral health behaviors, dental knowledge, and beliefs was assessed using a pretest-posttest design, with an additional six-month follow-up. Tests of repeated measures using Generalized Linear Models were conducted to assess changes in oral health knowledge, beliefs, and behaviors.

RESULTS

Knowledge and beliefs significantly increased as a result of the intervention and persisted after six months. A consistent, significant increase in positive oral health behaviors from baseline to six-months was also observed.

CONCLUSIONS

The results of this intervention study suggest promise for traditional storytelling to increase oral health-related knowledge, beliefs, and behaviors among self-identified AIAN pregnant women and mothers.

The Healthy Children, Strong Families 2 (HCSF2) Randomized Controlled Trial Improved Healthy Behaviors in American Indian Families with Young Children

BACKGROUND

American Indian (AI) families experience a disproportionate risk of obesity due to a number of complex reasons, including poverty, historic trauma, rural isolation or urban loss of community connections, lack of access to healthy foods and physical activity opportunities, and high stress. Home-based obesity prevention interventions are lacking for these families.

OBJECTIVE

Healthy Children, Strong Families 2 (HCSF2) was a randomized controlled trial of a healthy lifestyle promotion/obesity prevention intervention for AI families.

METHODS

Four hundred and fifty dyads consisting of an adult primary caregiver and a child ages 2 to 5 y from 5 AI communities were randomly assigned to a monthly mailed healthy lifestyle intervention toolkit (Wellness Journey) with social support or to a child safety control toolkit (Safety Journey) for 1 y. The Wellness Journey toolkit targeted increased fruit/vegetable (F/V) intake and physical activity, improved sleep, decreased added sugar intake and screen time, and improved stress management (adults only). Anthropometrics were collected, and health behaviors were assessed via survey at baseline and at the end of Year 1. Adults completed surveys for themselves and the participating child. Repeated measures analysis of variance was used to assess change over the intervention period.

RESULTS

Significant improvements to adult and child healthy diet patterns, adult F/V intake, adult moderate-to-vigorous physical activity, home nutrition environment, and adult self-efficacy for health behavior change were observed in Wellness Journey compared with Safety Journey families. No changes were observed in adult body mass index (BMI), child BMI z-score, adult stress measures, adult/child sleep and screen time, or child physical activity. Qualitative feedback suggests the intervention was extremely well-received by both the families and our community partners across the 5 participating sites.

CONCLUSIONS

This multi-site community-engaged intervention addressed key gaps regarding family home-based approaches for early obesity prevention in AI communities and showed several significant improvements in health behaviors. Multiple communities are working to sustain intervention efforts. This trial was registered at clinicaltrials.gov as NCT01776255.

Retrospective Study Demonstrating High Rates of Sustained Virologic Response After Treatment With Direct-Acting Antivirals Among American Indian/Alaskan Natives

Background

Treatment for chronic hepatitis C virus (HCV) has rapidly evolved to simple, well-tolerated, all-oral regimens of direct-acting antivirals (DAAs). There are few data on the epidemiology of HCV in American Indians/Alaska Natives (AI/ANs), a population disproportionately affected by HCV.

Methods

In this retrospective cohort study, all HCV-infected AI/AN patients treated with DAA therapies between January 1, 2014, and February 24, 2016, in specialty clinics or by primary care clinicians participating in Extension for Community Healthcare Outcomes (ECHO) were included. Demographic, clinical, and virologic data on all patients treated for HCV from pretreatment through sustained virologic response at 12 weeks (SVR12) were collected.

Results

Two hundred eighty patients were included; 71.1% of patients (n = 199) were infected with genotype 1 (GT1), 18.2% (n = 51) with GT2, and 10.7% with (n = 30) GT3. At baseline, 26.1% (n = 73) patients had cirrhosis and 22.6% (n = 56) had active substance use disorder; eighty-eight percent (n = 232) of patients achieved SVR12. Among the 165 GT1 patients treated with sofosbuvir (SOF)/ledipasvir for 8, 12, and 24 weeks, SVR12 was achieved by 91.5% (n = 54), 92.2% (n = 71), and 100% (n = 13), respectively. Among GT2 patients, 87.2% (n = 34) and 71.4% (n = 5) treated with 12 and 16 weeks of SOF/ribavirin (RBV) achieved SVR12, respectively. Among GT3 patients, 100% (n = 2) and 83.3% (n = 20) treated with 12 and 24 weeks of SOF/RBV achieved SVR12, respectively. SVR12 rates remained high among patients with active substance use disorder.

Conclusions

DAA therapies are highly efficacious in HCV-infected AI/ANs. SVR12 rates remained high among patients with active substance use disorder. More steps must be taken to increase access to treatment for this underserved, vulnerable population.

A County-Level Health Index to Capture Geographic Variation in Health Conditions in North Dakota, South Dakota, and Minnesota

INTRODUCTION

Individual health is influenced by multiple, potentially correlated factors including healthcare availability, community context, and socioeconomic factors. To measure the health changes at county-levels across North Dakota, South Dakota, and Minnesota, a measure of relative health, health index, was developed incorporating multiple indicators from domains of health conditions, health behaviors, and social determinants.

METHODS

We combined data from all 206 counties in the aforementioned three states for the years 2008-2012 from multiple data sources. We performed factor analysis that accounted for a hierarchical structure of the overall health index comprising of 15 indicators.

RESULTS

A hierarchical structure is identified in which three intermediate factors are connecting the health index with 15 health indicators. The grouping results of the 206 counties based on health index values demonstrate the existence of a gradient in health conditions in the Northern Plains.

CONCLUSIONS

The health status of urban areas was generally better than that of rural areas in the Northern Plains during this study period. The developed index adds stability to the estimates of the population characteristics, especially in rural, sparsely populated counties.
