Alcohol-attributable mortality among American Indians and Alaska Natives in the United States, 1999-2009

Native American Adolescents' Substance Use and Opportunity of Usage Substances: An Explanation Within Self-Control Theory

Background: Substance abuse and addiction among Native American adolescents have continually been problematic in the United States as their substance use can lead to detrimental consequences related to physical and mental health. Objectives: Relevant to the problem, this study applied Gottfredson and Hirschi's theory to explore the relationship between parental monitoring, low self-control, opportunity, and substance use among Native American adolescents. This study utilized a research project which Native American adolescents participated in a survey regarding substance abuse (n = 2,291). Results: The results indicated that opportunity significantly mediated the relationship between low self-control and substance use. Further, we found that parental monitoring played a crucial role in the relationship between opportunity and substance abuse. Conclusions: Overall, the findings provide a better understanding of why Native American adolescents may partake in substance use.

Enhancing Hepatitis C Management: Mortality Trends and Disparities in the US by Sex, Age Group, Race/Ethnicity and Region (1999-2020)

Hepatitis C virus (HCV) infection affects approximately 3.9 million people in the United States (U.S.), leading to 8000 to 10,000 deaths annually. Despite advancements in curative treatments since 2014, effective strategies targeting high-risk groups are crucial. This study examines HCV-related mortality trends from 1999 to 2020, focusing on demographic and regional disparities using the CDC WONDER database. A retrospective analysis was conducted using the CDC WONDER database. HCV-related deaths were identified using the International Classification of Diseases, Tenth Revision (ICD-10) codes B17.1 and B18.2. Mortality data were categorised by gender, age, race/ethnicity, region, place of death and urbanisation status. We calculated crude mortality rates (CRs) and age-adjusted mortality rates (AAMRs) per 100,000 population. Joinpoint regression analysis identified significant changes in mortality trends. A total of 324,008 HCV-related deaths were reported. The overall AAMR was 4.27 (95% Confidence Interval [CI]: 4.25 to 4.28). Mortality increased from 1999 to 2014 (1999 to 2007 Annual Percent Change [APC]: 5.00; 2007 to 2014 APC: 1.95) and declined sharply from 2014 to 2020 (APC: -7.11). Males exhibited higher mortality (AAMR: 6.28) than females (AAMR: 2.42). The 55-64 years age group had the highest CR (16.38), while non-Hispanic (NH) American Indians had the highest rate (AAMR: 8.72) among racial groups. Regionally, the South had the highest AAMR (5.80), nearly double that of the West (2.23) and Midwest (2.62). HCV-related mortality trends show significant demographic disparities and regional variations. Targeted interventions are essential to reduce HCV burden, particularly among vulnerable groups.

Depressive symptoms, alcohol use, and alcohol-related consequences: the moderating role of gender among American Indian adolescents

OBJECTIVES

Depression, alcohol use, and alcohol-related consequences are experienced disproportionately by American Indian (AI) adolescents. The co-occurrence of depression and alcohol use is clinically relevant, as it is associated with increased risk for suicide, among other negative consequences. Understanding how the association between depressive symptoms and alcohol use and related consequences is influenced by gender is important to understand for whom intervention efforts might be particularly relevant. Thus, the present study seeks to evaluate gender differences in these associations among AI adolescents.

METHODS

Participants were a representative sample of AI adolescents (N = 3,498, Mage=14.76, 47.8% female) residing on or near reservations who completed self-report questionnaires in school classrooms. Study activities were approved by IRB, school boards, and tribal authorities.

RESULTS

The interaction of depressive symptoms and gender was significant in predicting past-year alcohol use frequency (b=.02, p=.02) and, among youth reporting lifetime alcohol use, alcohol-related consequences (b=.03, p=.001). Analysis of simple slopes revealed that, for females, depressive symptoms were significantly associated with past-year alcohol use frequency (b=.02, p<.001) and alcohol-related consequences (b=.05, p<.001). For males, depressive symptoms were only significantly associated with alcohol-related consequences (b=.02, p=.04), and this effect was weaker than for females.

CONCLUSIONS

Results of the present study may inform the development of gender-sensitive recommendations for the assessment and treatment of alcohol use and alcohol-related consequences among AI adolescents. For instance, results suggest that treatments focusing on depressive symptoms may subsequently reduce alcohol use and related consequences for female AI adolescents.

Sovereignty For Your Body: Acceptability of Sexual Victimization Risk Reduction Interventions among Indigenous College Students

Objective

The goal of this study is to understand what type of sexual violence risk reduction intervention programs and elements are acceptable to Indigenous college students via quantitative survey research methods.

Method

401 Indigenous college students (77.1% women, 19.7% men, 3.0% trans or Two Spirit) from across North America were recruited. Students read standardized descriptions of four different sexual victimization risk reduction interventions (SVRRIs) that ranged in characteristics and ranked the interventions. All students provided acceptability ratings for Flip the Script with Enhanced Assess, Acknowledge, Act (EAAA) and a program of their choice. Participants also rated the importance of specific intervention elements, including cultural content.

Results

Most participants had a history of sexual victimization; 80.8% had been sexually victimized at some point in their life. The combined sexual violence and substance use reduction intervention (Sexual Assault Risk and Alcohol Use Reduction Program [SAARR]) was most frequently ranked as the first choice by 36.2% of the sample, p < 0.1. Considering acceptability ratings, all four SVRRIs were considered acceptable by most of the sample, with Flip the Script with EAAA rated highest of acceptability at 95.3% and Bringing in the Bystander having the lowest rate of acceptability at 71.4%. Cultural content was rated as a moderately important intervention element.

Conclusions

Indigenous college students are open to many different forms of sexual violence risk reduction interventions. Our findings suggest that simple cultural adaptations would be welcomed and scientifically supported to increase access and acceptability to violence interventions for Indigenous college students.

US mortality trends from alcohol-associated hepatitis by sex, age, race, and ethnicity, 1999-2020

BACKGROUND

Alcohol-associated hepatitis (AH) is a subtype of alcohol-associated liver disease (ALD) resulting in severe acute liver inflammation. This study aims to examine longitudinal trends in mortality from AH in the United States (US) from 1999 to 2020, stratifying the data by sex, age, and racial/ethnic groups.

METHODS

We performed a cross-sectional study using data from the US Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research (WONDER) to determine annual AH-related mortality rates (MR) in adults ≥21 years between 1999 and 2020. Data were stratified by sex, race, and 10-year age groups. Considering 1999 as baseline, mortality rate ratio (MRR) was calculated to characterize the MR in a particular year compared to baseline. Joinpoint regression analysis was conducted to characterize year-wise log-linear time calendar trends in MR.

RESULTS

From 1999 through 2020, AH-related deaths doubled from 0.5 per 100,000 (95% CI 0.5 to 0.6) to 1.1 per 100,000 (95% CI 1.1 to 1.2). While mortality rates for males doubled from 0.8 per 100,000 (95% CI 0.7 to 0.8) to 1.5 per 100,000 (95% CI 1.4 to 1.6), mortality rates for females almost tripled from 0.3 per 100,000 (9%% CI 0.3 to 0.4) to 0.8 per 100,000 (95% CI 0.7 to 0.8). The steepest increase in AH-related deaths from 1999 to 2020 were among American Indians/Alaska Natives and young adults 25-34 years, and particularly young adult females.

CONCLUSIONS

Over the past two decades, overall AH-related mortality in the US has doubled. The steepest increase in AH-related mortality was noted among American Indians/Alaska Natives and young adults, particularly young adult females. Education and prevention efforts should target these high-risk populations, and studies aimed at elucidating biological and sociodemographic factors resulting in the differential rise in mortality are warranted.

Disparities, Trends, and Predictions to 2040 in Gastrointestinal Cancer Incidence, Mortality in the United States

INTRODUCTION

Growing gastrointestinal cancers in the United States necessitate further research due to substantial health care and economic impacts. The aim of this study was to analyze trends and future projections for 5 major gastrointestinal cancers (colorectal, pancreatic, liver, stomach, and esophageal).

METHODS

Data were sourced from the Surveillance, Epidemiology, and End Results database; National Center for Health Statistics; and Global Burden of Diseases databases. An age-period-cohort model using the Bayesian Information Criterion method was applied to project incidence and mortality rates to 2040.

RESULTS

Men consistently exhibited higher incidence and mortality rates across all gastrointestinal cancers, with significant variation across the 51 US states. From 2000 to 2020, colorectal cancer incidence and mortality rates declined across all racial groups, except for the incidence rates of American Indian and Alaska Native (AIAN) men, Hispanic men, and Hispanic women, which remained stable. Pancreatic cancer incidence increased across all groups except for AIAN men, while mortality rates rose only for White men and Hispanic women. Liver cancer incidence rose among AIAN men and White, AIAN, and Hispanic women, while mortality rates declined for most groups. Stomach cancer incidence and mortality either declined or stabilized, and esophageal cancer rates showed a general decline. By 2040, increases in incidence and mortality are projected for most gastrointestinal cancers, particularly in men.

DISCUSSION

Despite varied trends over the past 2 decades, an overall increase in gastrointestinal cancer incidence and mortality rates is anticipated in the next 20 years in the United States, underscoring the need for effective prevention and intervention strategies.

Alcohol consumption, life history and extinction risk among Raute hunter-gatherers from Nepal

Hunter-gatherer populations underwent a mass extinction in the Neolithic, and in present times face challenges such as explicit sedentarisation policies. An exception is in Nepal, where the nomadic Raute people receive monthly governmental individual payments. One consequence of the money transfers has been a significant increase in alcohol consumption, with nearly all individuals drinking industrially produced alcohol. Here we investigate the Raute demography based on a full census of 144 individuals. We show that the Raute exhibit the short life expectancies typical of other hunter-gatherer populations from Africa, Asia and America. Bayesian survival trajectory analysis demonstrated that heavy drinking by either parent substantially reduces offspring survival to age 15. Bayesian regressions revealed a significant effect of heavy drinking on maternal fertility by decreasing the number of living children and reducing the proportion of live children at the end of maternal reproductive life. Although the absence of data prior to monetary support precludes a direct assessment of long-term demographic trends, relatively stable population sizes over the last decades and a fertility rate close to the replacement rate rule out an imminent population crash. Further studies are required to elucidate the Rautes' origins and relationship with other nomadic people in the region.

Area-Level Social Determinants of Alcohol-Related Mortality: Knowledge Gaps and Implications for Community Health

PURPOSE

Rates of alcohol-related mortality (including deaths attributed to chronic alcohol use as well as acute causes involving alcohol) have been increasing in the United States, particularly for certain population subgroups, such as women. This review summarizes associations of area-level social determinants of health with alcohol-related mortality. These determinants, measured at the community, county, or state level, include alcohol control policies, health care availability, and a community's socioeconomic environment. Examining multiple geographic levels illuminates how macro-level social determinants and local contexts contribute to alcohol-related mortality to inform intervention. Attention to the broad variety of social determinants of alcohol-related mortality could ultimately improve community health.

SEARCH METHODS

A literature search of three databases-PubMed, Web of Science, and Cumulative Index to Nursing and Allied Health Literature (CINAHL)-conducted between March 13 and May 16, 2023, identified peer-reviewed studies published from 1990 to May 2023 that modeled at least one area-level social determinant of health as a predictor or correlate of area-level rates of alcohol-related mortality in the United States. Unpublished dissertations, commentaries, editorials, review papers, and articles published in languages other than English were excluded. Two team members reviewed each abstract to verify that the article addressed alcohol-related mortality and included at least one area-level social determinant of health.

SEARCH RESULTS

The authors screened 313 abstracts and excluded 210 that did not meet inclusion criteria. The full texts of 103 articles were retrieved. Upon further screening, 30 articles were excluded (two were not obtained), leaving 71 studies for detailed review.

DISCUSSION AND CONCLUSIONS

Many studies analyzed fatal alcohol-related motor vehicle crashes or cirrhosis/liver disease mortality. Fewer analyzed other mortality causes related to chronic alcohol consumption. No studies focused on racism and discrimination, community-level prevention activities, or community social services in relation to alcohol-related mortality. Few studies examined major health policy changes or addressed health care system factors. Although the variation across studies complicates systematic comparison of the results, some key themes did emerge from the reviewed studies, such as the beneficial effects of stronger alcohol policies and the importance of socioeconomic conditions as determinants of alcohol-related mortality. Research using a more diverse set of theoretically informed social determinants may help examine whether, how, and for whom racism and discrimination as well as health policies and social services impact alcohol-related mortality. Finally, there is a gap in research linking local community contexts with alcohol-related mortality. Better understanding of subgroup differences, interactions between different contextual factors, and specific mechanisms of action may help identify promising new strategies to improve population health and reduce alcohol-related mortality.

Exploring Racial/Ethnic Disparities in Substance Dependence and Serious Psychological Distress among US Veterans

OBJECTIVES

There are substantial racial/ethnic disparities in substance use and mental health among civilian populations, but few studies have examined these disparities in veterans using a nationally representative sample. Thus, we examined differences in substance dependence and serious psychological distress (SPD) by race/ethnicity among a national sample of US veterans.

METHODS

We pooled cross-sectional data from the 2015-2019 waves of the National Survey on Drug Use and Health (N = 7,653 veterans aged 18-64 years). Regression models were utilized to examine racial/ethnic differences in DSM-IV substance dependence and SPD with a Benjamini-Hochberg correction applied.

RESULTS

Compared to non-Hispanic White veterans: American Indian/Alaska Native veterans had significantly higher odds of past-year alcohol dependence (AOR = 2.55, 95% CI: 1.28, 5.08); Asian American veterans had significantly lower odds of past-year alcohol dependence (AOR = 0.12, 95% CI: 0.02, 0.62); non-Hispanic Black (AOR = 0.60, 95% CI: 0.48, 0.77), Hispanic (AOR = 0.47, 95% CI: 0.34, 0.65), and veterans of more than one race (AOR = 0.55, 95% CI: 0.36, 0.83) had significantly lower odds of past-month nicotine dependence; Asian American veterans had significantly lower odds of past-year illicit drug dependence (AOR = 0.05, 95% CI: 0.01, 0.35); and non-Hispanic Black veterans had significantly lower odds of past-year SPD (AOR = 0.69, 95% CI: 0.55, 0.85) after correction for multiple comparisons.

CONCLUSION

Overall, racial/ethnic disparities in substance dependence and SPD among veterans are not as stark as in civilian populations, but some disparities remain.

The burden of cirrhosis mortality by county, race, and ethnicity in the USA, 2000-19: a systematic analysis of health disparities

BACKGROUND

Cirrhosis is responsible for substantial health and economic burden in the USA. Reducing this burden requires better understanding of how rates of cirrhosis mortality vary by race and ethnicity and by geographical location. This study describes rates and trends in cirrhosis mortality for five racial and ethnic populations in 3110 US counties from 2000 to 2019.

METHODS

We estimated cirrhosis mortality rates by county, race and ethnicity, and year (2000-19) using previously validated small-area estimation methods, death registration data from the US National Vital Statistics System, and population data from the US National Center for Health Statistics. Five racial and ethnic populations were considered: American Indian or Alaska Native (AIAN), Asian or Pacific Islander (Asian), Black, Latino or Hispanic (Latino), and White. Cirrhosis mortality rate estimates were age-standardised using the age distribution from the 2010 US census as the standard. For each racial and ethnic population, estimates are presented for all counties with a mean annual population greater than 1000.

FINDINGS

From 2000 to 2019, national-level age-standardised cirrhosis mortality rates decreased in the Asian (23·8% [95% uncertainty interval 19·6-27·8], from 9·4 deaths per 100 000 population [8·9-9·9] to 7·1 per 100 000 [6·8-7·5]), Black (22·8% [20·6-24·8], from 19·8 per 100 000 [19·4-20·3] to 15·3 per 100 000 [15·0-15·6]), and Latino (15·3% [13·3-17·3], from 26·3 per 100 000 [25·6-27·0] to 22·3 per 100 000 [21·8-22·8]) populations and increased in the AIAN (39·3% [32·3-46·4], from 45·6 per 100 000 [40·6-50·6] to 63·5 per 100 000 [57·2-70·2] in 2000 and 2019, respectively) and White (25·8% [24·2-27·3], from 14·7 deaths per 100 000 [14·6-14·9] to 18·5 per 100 000 [18·4-18·7]) populations. In all years, cirrhosis mortality rates were lowest among the Asian population, highest among the AIAN population, and higher in males than females for each racial and ethnic population. The degree of heterogeneity in county-level cirrhosis mortality rates varied by racial and ethnic population, with the narrowest IQR in the Asian population (median 8·0 deaths per 100 000, IQR 6·4-10·4) and the widest in the AIAN population (55·1, 30·3-78·8). Cirrhosis mortality increased over the study period in almost all counties for the White (2957 [96·9%] of 3051 counties) and AIAN (421 [88·8%] of 474) populations, but in a smaller proportion of counties for the Asian, Black, and Latino populations. For all racial and ethnic populations, cirrhosis mortality rates increased in more counties between 2000 and 2015 than between 2015 and 2019.

INTERPRETATION

Cirrhosis mortality increased nationally and in many counties from 2000 to 2019. Although the magnitude of racial and ethnic disparities decreased in some places, disparities nonetheless persisted, and mortality remained high in many locations and communities. Our findings underscore the need to implement targeted and locally tailored programmes and policies to reduce the burden of cirrhosis at both the national and local level.

Evaluating Two Educational Interventions for Enhancing COVID-19 Knowledge and Attitudes in a Sample American Indian/Alaska Native Population

BACKGROUND

The COVID-19 pandemic has exacerbated existing healthcare disparities among American Indian/Alaska Native (AI/AN) populations rooted in historical traumas and systemic marginalization.

METHODS

This study conducted at a single Indian Health Service (IHS) clinic in central Michigan evaluates two educational interventions for enhancing COVID-19 knowledge and attitudes in a sample AI/AN population. Utilizing a pre/post-intervention prospective study design, participants received either a video or infographic educational intervention, followed by a survey assessing their COVID-19 knowledge and attitudes.

RESULTS

The results indicate significant improvements in knowledge and attitudes post-intervention, with both modalities proving effective. However, specific factors such as gender, political affiliation, and place of residence influenced COVID-19 attitudes and knowledge, emphasizing the importance of tailored interventions.

CONCLUSIONS

Despite limitations, this study highlights the critical role of educational interventions in addressing vaccine hesitancy and promoting health equity within AI/AN communities. Moving forward, comprehensive strategies involving increased Indian Health Service funding, culturally relevant interventions, and policy advocacy are crucial in mitigating healthcare disparities and promoting health equity within AI/AN communities.

Excess mortality among individuals who have undergone addiction treatment: a study from Greenland

In Greenland, where addiction-related concerns significantly affect well-being, research has explored alcohol's impact on health and mortality. However, no studies have focused on mortality among those who received addiction treatment. This study investigates whether individuals treated for addiction in Greenland experience elevated mortality rates compared to the general population. The study encompassed individuals receiving addiction treatment through the national system between 2012 and December 31, 2022. Data on treatment were sourced from the National Addiction Database, and Statistics Greenland. Person-years at risk were calculated and used to estimate crude mortality rates (CMRs). Adjusted standardized mortality rates (SMRs), accounting for age, sex, and calendar year, were estimated using an indirect method based on observed and expected deaths. Of the 3286 in treatment, 53.9% were women, with a median age of 37. About a third had undergone multiple treatment episodes, and 60.1% received treatment in 2019 or later. The cohort was followed for a median of 2.89 years, yielding 12,068 person-years. The overall CMR was 7.79 deaths per 1000 person-years, with a SMR of 1.42 (95% confidence interval: 1.15; 1.74). Significantly, SMRs differed by age at treatment entry, with younger groups exhibiting higher SMRs (p value = .021). This study found that individuals seeking treatment for addiction problems in Greenland had a higher mortality rate than the general population. Importantly, these SMRs were substantially lower than those observed in clinical populations in other countries.

Negative Affect and Drinking among Indigenous Youth: Disaggregating Within- and Between-Person Effects

Negative affect (depression/anxiety) and alcohol use among Indigenous youth in Canada remain a concern for many communities. Disparate rates of these struggles are understood to be a potential outcome of colonization and subsequent intergenerational trauma experienced by individuals, families, and communities. Using a longitudinal design, we examined change in alcohol use and negative affect, and reciprocal associations, among a group of Indigenous adolescents. Indigenous youth (N = 117; 50% male; Mage=12.46-16.28; grades 6-10) from a remote First Nation in northern Quebec completed annual self-reported assessments on negative affect (depression/anxiety) and alcohol use. A Latent Curve Model with Structured Residuals (LCM-SR) was used to distinguish between- and within-person associations of negative affect and alcohol use. Growth models did not support change in depression/anxiety, but reports of drinking increased linearly. At the between-person level, girls reported higher initial levels of depression/anxiety and drinking; depression/anxiety were not associated with drinking. At the within-person level, drinking prospectively predicted increases in depression/anxiety but depression/anxiety did not prospectively predict drinking. When Indigenous adolescents reported drinking more alcohol than usual at one wave of assessment, they reported higher levels of negative affect than expected (given their average levels of depression/anxiety) at the following assessment. Our findings suggest that when Indigenous youth present for treatment reporting alcohol use, they should also be screened for negative affect (depression/anxiety). Conversely, if an Indigenous adolescent presents for treatment reporting negative affect, they should also be screened for alcohol use.

Changes in alcohol consumption and binge drinking during the COVID-19 pandemic among American Indians residing in California and Oklahoma

Background: This study explored the increased quantity and frequency of alcohol use in the American Indian (AI) population during the COVID-19 pandemic.Objectives: The aims of this study were to explore possible associations between covariables and both binge drinking and alcohol consumption during COVID-19.Methods: This cross-sectional survey study analyzed data from a sample of AI individuals (63% female) residing in California (n = 411) and Oklahoma (n = 657) between October 2020-January 2021. Analysis included summary statistics and multivariable logistic regression, including a variety of socio-economic, COVID-19 concern, and tobacco and marijuana use variables.Results: One or more alcohol binge episodes were reported between October 2020-January 2021 in 19.3% of participants and elevated overall alcohol consumption was reported by 21.6% of participants. Higher odds of elevated alcohol consumption occurred in women and those following more social distancing measures. The odds of binge drinking or elevated alcohol consumption in those using both marijuana and tobacco (aOR/ adjusted odds ratio:18.9, 95% CI = 8.5, 42.2, and aOR:3.9, 95% CI = 1.7, 8.6, respectively) were higher compared to those using neither. Similarly, the odds of binge drinking or elevated alcohol consumption in those using tobacco only (aOR:4.7, 95% CI = 2.9, 7.7 and aOR: 2.0, 95% CI = 1.1, 3.5, respectively) were higher compared to those using neither.Conclusions: This study found high rates of alcohol use and bingeing during the COVID-19 pandemic. Offering collaborative, culturally sensitive, and affordable support services are important components of intervention and preparation for future stressful events on local, as well as global levels.

A systematic meta-epidemiologic review on nonabstinence-inclusive interventions for substance use: inclusion of race/ethnicity and sex assigned at birth/gender

Background: Minoritized racial/ethnic and sex assigned at birth/gender groups experience disproportionate substance-related harm. Focusing on reducing substance-related harm without requiring abstinence is a promising approach.Objectives: The purpose of this meta-epidemiologic systematic review was to examine inclusion of racial/ethnic and sex assigned at birth/gender in published studies of nonabstinence-inclusive interventions for substance use.Methods: We systematically searched databases (PubMed and PsycINFO) on May 26, 2022 following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Articles were eligible for inclusion if they: 1) reported in English language, 2) had a primary goal of investigating a nonabstinence-inclusive intervention to address substance use, 3) used human subjects, and 4) only included adults aged 18 or older. Two coders screened initial articles and assessed eligibility criteria of full text articles. A third consensus rater reviewed all coding discrepancies. For the remaining full-length articles, an independent rater extracted information relevant to study goalsResults: The search strategy yielded 5,759 records. 235 included articles remained. Only 73 articles (31.1%) fully reported on both racial/ethnic and sex assigned at birth/gender, and only seven articles (3.0%) reported subgroup analyses examining treatment efficacy across minoritized groups. Nine articles (3.8%) mentioned inclusion and diversity regarding both racial/ethnic and sex assigned at birth/gender in their discussion and four articles (1.7%) broadly mentioned a lack of diversity in their limitationsConclusion: Findings highlight that little is known about nonabstinence-inclusive interventions to address substance use for individuals from minoritized racial/ethnic and sex assigned at birth/gender groups.

Investigating the role of emotion regulation in the relationship between childhood trauma and alcohol problems in American Indian adults

OBJECTIVE

To investigate whether use of cognitive reappraisal and expressive suppression interact with childhood trauma burden to predict alcohol problems in a sample of American Indian adults.

METHODS

Four hundred and twenty-nine American Indian adults (Mean age = 37.62, 59.5 % male) completed an online survey to measure childhood trauma exposure, perceived impact of childhood trauma, trait use of expressive suppression, and alcohol problems in adulthood.

RESULTS

Trait use of cognitive reappraisal and expressive suppression interacted with childhood trauma burden to predict alcohol problems in adulthood. American Indian adults who reported high levels of childhood trauma burden who also reported frequent use of both cognitive reappraisal and expressive suppression had significantly more alcohol problems compared to individuals who reported similarly high levels of childhood trauma burden who reported low use of these emotion regulation strategies.

CONCLUSIONS

These findings provide initial evidence that emotion regulation interventions which focus on different emotion regulation strategies could be an effective way to offset the risk for alcohol problems associated with childhood trauma.

Misracialization of Indigenous people in population health and mortality studies: a scoping review to establish promising practices

Indigenous people are often misracialized as other racial or ethnic identities in population health research. This misclassification leads to underestimation of Indigenous-specific mortality and health metrics, and subsequently, inadequate resource allocation. In recognition of this problem, investigators around the world have devised analytic methods to address racial misclassification of Indigenous people. We carried out a scoping review based on searches in PubMed, Web of Science, and the Native Health Database for empirical studies published after 2000 that include Indigenous-specific estimates of health or mortality and that take analytic steps to rectify racial misclassification of Indigenous people. We then considered the weaknesses and strengths of implemented analytic approaches, with a focus on methods used in the US context. To do this, we extracted information from 97 articles and compared the analytic approaches used. The most common approach to address Indigenous misclassification is to use data linkage; other methods include geographic restriction to areas where misclassification is less common, exclusion of some subgroups, imputation, aggregation, and electronic health record abstraction. We identified 4 primary limitations of these approaches: (1) combining data sources that use inconsistent processes and/or sources of race and ethnicity information; (2) conflating race, ethnicity, and nationality; (3) applying insufficient algorithms to bridge, impute, or link race and ethnicity information; and (4) assuming the hyperlocality of Indigenous people. Although there is no perfect solution to the issue of Indigenous misclassification in population-based studies, a review of this literature provided information on promising practices to consider.

An Updated Narrative Review on the Role of Alcohol Among Indigenous Communities

Purpose of Review

The role of alcohol varies considerably among Indigenous Peoples and is the backdrop of persistent stereotypes despite decades of research. This paper provides an updated narrative review on the alcohol literature among Indigenous communities, highlighting recent studies published since 2017.

Recent Findings

We examined published literature involving alcohol use rates, including abstinence; risk and protective factors; treatment; and recovery, as well as future directions for alcohol prevention and intervention efforts with Indigenous communities.

Summary

Evidence-based alcohol use prevention, intervention, and recovery strategies with Indigenous communities are outlined. Recommendations are provided for researchers, health providers, and public policy advocates to address and better understand alcohol use, treatment, prevention, and recovery among Indigenous Peoples. Specific recommendations include using community-based participatory research strategies and harm reduction approaches to prevent and treat alcohol use problems with Indigenous communities. Future research is needed to elucidate mechanisms of resilience and recovery from Alcohol Use Disorder and possible shifts in perceptions of alcohol use for Indigenous Peoples.

Alzheimer's disease and its related dementias in US Native Americans: A major public health concern

Alzheimer's disease (AD) and Alzheimer's related dementias (ADRD) are growing public health concerns in aged populations of all ethnic and racial groups. AD and ADRD are caused by multiple factors, such as genetic mutations, modifiable and non-modifiable risk factors, and lifestyle. Studies of postmortem brains have revealed multiple cellular changes implicated in AD and ADRD, including the accumulation of amyloid beta and phosphorylated tau, synaptic damage, inflammatory responses, hormonal imbalance, mitochondrial abnormalities, and neuronal loss. These changes occur in both early-onset familial and late-onset sporadic forms. Two-thirds of women and one-third of men are at life time risk for AD. A small proportion of total AD cases are caused by genetic mutations in amyloid precursor protein, presenilin 1, and presenilin 1 genes, and the APOE4 allele is a risk factor. Tremendous research on AD/ADRD, and other comorbidities such as diabetes, obesity, hypertension, and cancer has been done on almost all ethnic groups, however, very little biomedical research done on US Native Americans. AD/ADRD prevalence is high among all ethnic groups. In addition, US Native Americans have poorer access to healthcare and medical services and are less likely to receive a diagnosis once they begin to exhibit symptoms, which presents difficulties in treating Alzheimer's and other dementias. One in five US Native American people who are 45 years of age or older report having memory issues. Further, the impact of caregivers and other healthcare aspects on US Native Americans is not yet. In the current article, we discuss the history of Native Americans of United States (US) and health disparities, occurrence, and prevalence of AD/ADRD, and shedding light on the culturally sensitive caregiving practices in US Native Americans. This article is the first to discuss biomedical research and healthcare disparities in US Native Americans with a focus on AD and ADRD, we also discuss why US Native Americans are reluctant to participate in biomedical research.

Measurement Invariance and Application of an Alcohol-Related Consequence Scale for American Indian Adolescents

American Indian (AI) adolescents experience disproportionate alcohol-related consequences. The present study evaluated the psychometric properties and application of the American Drug and Alcohol Survey (ADAS™) alcohol-related consequence scale for AI adolescents through a secondary analysis of a large population-based sample of adolescents living on or near AI reservations. We found support for the ADAS alcohol-related consequence scale as a one-factor model, invariant discretely across race, sex assigned at birth, and age, and with good internal consistency. Evidence for construct validity was found through significant positive correlations between frequency of past 12 months of drinking, frequency of past 12 months of intoxication, and lifetime alcohol-related consequences. AI adolescents were significantly more likely to report more alcohol-related consequences than their non-Hispanic White peers. Race significantly interacted with frequency of drinking in predicting alcohol-related consequences such that these associations were stronger for AI adolescents. However, race did not significantly interact with frequency of intoxication in predicting alcohol-related consequences. Results from this study demonstrate the utility of the ADAS alcohol-related consequence scale for use across demographic groups with little risk of measurement bias.

The Cultural Adaption of a Sobriety Support App for Alaska Native and American Indian People: Qualitative Feasibility and Acceptability Study

BACKGROUND

Despite high rates of alcohol abstinence, Alaska Native and American Indian (ANAI) people experience a disproportionate burden of alcohol-related morbidity and mortality. Multiple barriers to treatment exist for this population, including a lack of culturally relevant resources; limited access to or delays in receiving treatment; and privacy concerns. Many ANAI people in the state of Alaska, United States, live in sparsely populated rural areas, where treatment access and privacy concerns regarding peer-support programs may be particularly challenging. In addition, prior research demonstrates that many ANAI people prefer a self-management approach to sobriety, rather than formal treatment. Taken together, these factors suggest a potential role for a culturally adapted smartphone app to support ANAI people interested in changing their behavior regarding alcohol use.

OBJECTIVE

This study was the first phase of a feasibility and acceptability study of a culturally tailored version of an off-the-shelf smartphone app to aid ANAI people in managing or reducing their use of alcohol. The aim of this qualitative needs assessment was to gather insights and preferences from ANAI people and health care providers serving ANAI people to guide feature development, content selection, and cultural adaptation before a pilot test of the smartphone app with ANAI people.

METHODS

From October 2018 to September 2019, we conducted semistructured interviews with 24 ANAI patients aged ≥21 years and 8 providers in a tribal health care organization in south-central Alaska.

RESULTS

Participants generally endorsed the usefulness of a smartphone app for alcohol self-management. They cited anonymity, 24/7 access, peer support, and patient choice as key attributes of an app. The desired cultural adaptations included ANAI- and land-themed design elements, cultural content (eg, stories from elders), and spiritual resources. Participants considered an app especially useful for rural-dwelling ANAI people, as well as those who lack timely access to treatment services or prefer to work toward managing their alcohol use outside the clinical setting.

CONCLUSIONS

This needs assessment identified key features, content, and cultural adaptations that are being implemented in the next phase of the study. In future work, we will determine the extent to which these changes can be accommodated in a commercially available app, the feasibility of implementation, and the acceptability of the culturally adapted version of the app among ANAI users.

Culturally sensitive prevention programs for substance use among adolescents of color: A systematic review and meta-analysis of randomized controlled trials

This systematic review and meta-analysis aims to synthesize the efficacy of culturally sensitive prevention programs for substance use outcomes among U.S. adolescents of color (aged 11 to 18 years old) and explore whether the intervention effects vary by participant and intervention characteristics. Eight electronic databases and grey literature were searched for eligible randomized controlled trials through September 2022. Robust variance estimation in meta-regression was used to synthesize treatment effect size estimates and to conduct moderator analysis. After screening, 30 unique studies were included. The average treatment effect size across all substance use outcomes (including 221 effect sizes) was Hedges's g = -0.20, 95% CI = [-0.24, -0.16]. The synthesized effect sizes were statistically significant across types of substances (alcohol, cigarette, marijuana, illicit and other drugs, and unspecified substance use), racial/ethnic groups (Hispanic, Black, and Native American), and different follow-ups (0-12 months, >12 months). Very few studies reported substance use consequences as outcomes and the synthesized effect size was non-significant. Meta-regression findings suggest that the intervention effects may vary based on the type of substance. This meta-analysis found supportive evidence of culturally sensitive prevention programs' efficacy in preventing or reducing substance use among Black, Hispanic, and Native American adolescents. More substance use prevention efforts and evidence is needed for Asian American, Pacific Islander, and multiracial adolescents.

Trends in Deaths Fully Attributable to Alcohol in Minnesota, 2000-2018

OBJECTIVE

Overall trends in rates of fully alcohol-attributable mortality may mask disparities among demographic groups. We investigated overall, demographic, and geographic trends in fully alcohol-attributable mortality rates in Minnesota.

METHODS

We obtained mortality data from Minnesota death certificates and defined fully alcohol-attributable deaths as deaths that would not occur in the absence of alcohol. We calculated age-adjusted death rates during 2000-2018 using 5-year moving averages stratified by decedents' characteristics and geographic location.

RESULTS

Chronic conditions accounted for most of the alcohol-attributable deaths in Minnesota (89% during 2014-2018). Alcohol-attributable mortality rates per 100 000 population increased from an average rate of 8.0 during 2000-2004 to 12.6 during 2014-2018. During 2000-2018, alcohol-attributable mortality rates were highest among males (vs females), adults aged 55-64 (vs other ages), and American Indian/Alaska Native people (vs other racial and ethnic groups) and lowest among people aged ≤24 years and Asian or Pacific Islander people. During 2014-2018, the alcohol-attributable mortality rate among American Indian/Alaska Native people was more than 5 times higher than the overall mortality rate in Minnesota.

CONCLUSIONS

Results from this study may increase awareness of racial and ethnic disparities and continuing health inequities and inform public health prevention efforts, such as those recommended by the Community Preventive Services Task Force, including regulating alcohol outlet density and increasing alcohol taxes.

Harm reduction acceptability and feasibility in a North American indigenous reserve community

AIMS

The present study assessed community and culturally specific alcohol-related harm among North American Indigenous (NAI) individuals, as well as the acceptability and feasibility of harm reduction approaches in one reserve-based NAI community.

METHODS

Participants lived on or near a NAI reserve in Canada. Semi-structured focus groups were conducted with health care workers (N = 8, 75% NAI) and community members (N = 9, 100% NAI). Self-report questionnaires were administered that measured acceptability and feasibility of harm reduction strategies.

RESULTS

Conventional content analysis revealed loss of culture as culturally specific alcohol-related harm. Health care workers rated harm reduction approaches to be acceptable and feasible, while community participants were more mixed. Majority of participants felt that some harm reduction strategies could provide opportunities for individuals who use alcohol to connect to Indigenous culture and traditions. However, there were mixed findings on whether harm reduction strategies are consistent with Indigenous cultural traditions and values.

CONCLUSION

Future research is needed to evaluate potential utility of harm-reduction approaches for NAI communities.

An update on ACEs domain frequencies across race/ethnicity and sex in a nationally representative sample

BACKGROUND

Adverse childhood experiences (ACEs) research has yielded important information regarding ACEs prevalence and impacts; however, few studies have included American Indian/Alaska Native (AI/AN) populations.

OBJECTIVE

We aimed to update and expand the ACEs literature by using recent data (2009-2018; over 50% from 2015 to 2017); using a large, nationally representative sample (total N = 166,606) and AI/AN sub-sample (N = 3369); and including additional covariates (i.e., sex, age, income, education) to provide a comprehensive understanding of ACEs across diverse populations.

PARTICIPANTS AND SETTING

Data were from the CDC's BRFSS, a standardized scale used in most ACEs literature, to improve generalizability of study findings, which may contribute to investigating future ACEs trends.

METHODS

Descriptive statistics and negative binomial regression analyses were conducted to examine the frequency of ACEs and the eight ACEs domains across racial/ethnic and sex groups.

RESULTS

AI/ANs had the highest ACEs compared to all racial/ethnic groups. Females had higher mean ACEs compared to males of the same racial/ethnic group; significant differences were identified between non-Hispanic White (NHW) females and NHW males, and between Hispanic females and Hispanic males. Across all 10 stratified subgroups, AI/AN females had the highest average ACEs followed by AI/AN males. Emotional abuse was the most reported ACEs domain across all individuals, and family incarceration was the lowest. AI/AN females and males had the highest ACEs frequencies in family substance use, witnessing intimate partner violence, and sexual and emotional abuse.

CONCLUSIONS

Findings have important implications for public health intervention and prevention efforts that may mitigate the impact of ACEs across racial/ethnic groups, particularly for AI/AN populations.

Subjective happiness interrupts the association between alcohol expectancies and alcohol consumption among reserve-dwelling first nation adolescents

North American Indigenous (NAI) youth suffers disproportionately from consequences associated with alcohol use. Previous research has found that positive alcohol expectancies are robustly related to alcohol consumption among NAI youth and that changes in alcohol consumption are associated with concurrent changes in happiness. However, no work to date has examined the relation between happiness and alcohol expectancies, or the influence of happiness on the association between alcohol expectancies and alcohol consumption. First Nation adolescents between the ages of 11 and 18 living on a rural reserve in Eastern Canada (N = 106, Mage = 14.6 years, 50.0% female) completed a pencil-and-paper survey regarding their subjective happiness, positive alcohol expectancies, and alcohol consumption. Moderation analyses revealed a significant main effect of subjective happiness (b = -.10, p < .001) but not alcohol expectancies (b = .02, p = .14) on alcohol consumption. The interaction of alcohol expectancies and subjective happiness was significant, (b = -.01, p = .002). Analysis of simple slopes revealed that the effect of alcohol expectancies on alcohol consumption was significant for those reporting low (b = .07, p = .001), but not high levels of subjective happiness (b = -.02, p = .25). Results of the present study provide preliminary support for the utility of positive psychological interventions aiming to increase adolescent's subjective happiness to indirectly target alcohol consumption. Future work should test the effectiveness of such interventions and aim to replicate these findings in larger samples. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Dual Diagnosis and Alcohol/Nicotine Use Disorders: Native American and White Hospital Patients in 3 States

INTRODUCTION

Nationally, mental illness prevalence is comparable among Native Americans and Whites experiencing alcohol and nicotine use disorders. However, authors are concerned that mental illness in Native Americans with substance use disorders may be disparately underdiagnosed in medical settings. For 3 states with large Native American populations, this study compares the prevalence of mental illness diagnoses among Native Americans and Whites hospitalized with alcohol/nicotine use disorders.

METHODS

In 2021, hospital discharge data were used to compare non-Hispanic Native Americans with non-Hispanic Whites in Arizona and New Mexico (2016-2018) and (regardless of Hispanic ethnicity) Native Americans with Whites in Oklahoma (2016-2017). Differences in any mental illness, mood, and anxiety diagnoses were assessed using multilevel regressions (adjusted for demographics, payor, comorbidities, facility). Adjusted predicted probabilities were constructed.

RESULTS

Among alcohol-related discharges, probabilities of non-Hispanic Native Americans and non-Hispanic Whites receiving any mental illness diagnoses in Arizona were 18.0% (95% CI=16.1, 19.9) and 36.8% (95% CI=34.1, 39.5), respectively; in New Mexico, they were 24.5% (95% CI=20.7, 28.3) and 43.4% (95% CI=38.7, 48.1). Oklahoma's probabilities for Native Americans and Whites were 30.7% (95% CI=27.4, 34.0) and 36.8% (95% CI=33.5, 40.2), respectively. Among nicotine-related discharges, any mental illness diagnosis probabilities for non-Hispanic Native Americans and non-Hispanic Whites in Arizona were 21.2% (95% CI=18.9, 23.5) and 33.1% (95% CI=30.3, 35.9), respectively; in New Mexico, they were 25.9% (95% CI=22.7, 29.1) and 37.4% (95% CI=33.8, 40.9). Oklahoma's probabilities for Native Americans and Whites were 27.3% (95% CI=25.1, 29.6) and 30.2% (95% CI=28.0, 32.4), respectively. Mood and anxiety diagnoses were also significantly lower for non-Hispanic Native Americans in Arizona/New Mexico and Native Americans in Oklahoma.

CONCLUSIONS

Findings suggest disparate underdiagnosis of mental illness among Native Americans hospitalized with alcohol/nicotine use disorders in the examined states.

Health-Related Behavioral Risk Factors and Obesity Among American Indians and Alaska Natives of the United States: Assessing Variations by Indian Health Service Region

INTRODUCTION

Health-related behavioral risk factors and obesity are linked to high risk for multiple chronic diseases. We examined the prevalence of these risk factors among American Indians and Alaska Natives (AI/ANs) compared with that of non-Hispanic Whites and across Indian Health Service (IHS) regions.

METHODS

We used 2017 Behavioral Risk Factor Surveillance System data from participants in 50 states and the District of Columbia to assess 4 behavioral risk factors (current cigarette smoking, heavy drinking, binge drinking, and physical inactivity) and obesity. We analyzed disparities in these risk factors between AI/AN and non-Hispanic White participants, nationwide and by IHS region, by conducting log-linear regression analyses while controlling for potential confounders.

RESULTS

Nationwide, crude prevalence of current smoking, physical inactivity, and obesity were significantly higher among AI/AN than non-Hispanic White participants. After adjustment for sociodemographic characteristics, AI/AN participants were 11% more likely to report current smoking (P < .05) and 23% more likely to report obesity (P < .001) than non-Hispanic White participants. These patterns persisted in most IHS regions with some exceptions. In the Southwest region, AI/AN participants were 39% less likely to report current smoking than non-Hispanic White participants (P < .001). In the Pacific Coast region, compared with non-Hispanic White participants, AI/AN participants were 54% less likely to report heavy drinking (P < .01) but 34% more likely to report physical inactivity (P < .05). Across IHS regions, AI/AN participants residing in Alaska and the Northern Plains regions had the highest prevalence of current smoking and binge drinking, and those in the Southwest and Pacific Coast regions had the lowest prevalence of current smoking. AI/AN participants in the Southwest region had the lowest prevalence of physical inactivity, and those in the Southern Plains region had the highest prevalence of obesity.

CONCLUSIONS

The findings of this study support the importance of public health efforts to address and improve behavioral risk factors related to chronic disease in AI/AN people, both nationwide and among IHS regions, through culturally appropriate interventions.

Positive Psychological Characteristics and Substance Use in First Nation Adolescents

BackgroundNorth American Indigenous (NAI) adolescents experience disproportionate harm related to substance use compared to non-Indigenous adolescents. Strengths-based approaches to substance use prevention and treatment are consistent with Indigenous conceptualizations of health, which tend to be holistic and incorporate more spirituality and community than mainstream Western conceptualizations. Despite this, little is known about how positive psychological characteristics that might confer protection relate to substance use among NAI adolescents. Thus, the present study aims to examine the relations among life satisfaction, subjective happiness, self-compassion, and cigarette, marijuana, alcohol, and other drug use. MethodsParticipants were 106 reserve-dwelling First Nation adolescents located in Eastern Canada (M_age= 14.6 years, 50.0% female) who completed a paper-and-pencil survey regarding their substance use and psychological characteristics for a larger community-based participatory research project. ResultsGreater life satisfaction was significantly associated with decreased odds of lifetime (OR = 0.88, 95%CI [0.81, 0.96]) and current cigarette smoking (OR = 0.90, 95%CI [0.82, 0.99]). Greater subjective happiness was significantly associated with decreased odds of current marijuana use (OR = 0.83, 95%CI [0.71, 0.97]). Although significantly correlated with lower lifetime use of other drugs, self-compassion was not significantly associated with lifetime or current odds of substance use after controlling for age, gender, and other positive characteristics. DiscussionThis is one of the first studies to evaluate positive characteristics and substance use in NAI adolescents. Results point to positive characteristics that may be useful in substance use prevention and suggest the need for further research to further elucidate these associations.

Perceived Racial Discrimination, Alcohol Use, and Alcohol-Related Problems: The Moderating Role of Self-Compassion in Reserve-Dwelling First Nation Youth

North American Indigenous youth experience disproportionate rates of racial discrimination as well as consequences associated with alcohol use. Self-compassion has been found to be related to both racial discrimination and alcohol use, separately. However, no work to date has examined the role of self-compassion as a moderator of the links among racial discrimination and alcohol use and alcohol-related problems. First Nation adolescents (N = 106, M age = 14.6, 50.0% female) from reserve communities in Eastern Canada completed a pencil-and-paper survey regarding their experiences of racial discrimination, self-compassion, alcohol use, and alcohol-related problems. The associations between racial discrimination and both alcohol use and alcohol-related problems were significantly moderated by self-compassion. Simple slopes analysis revealed that the associations between racial discrimination and alcohol use was significant for those with low (b = 6.03, p = .002) but not high (b = -0.30, p = .88) levels of self-compassion. Similarly, the association between racial discrimination and alcohol-related problems was significant for those with low (b = 21.81, p = .001) but not high (b = 0.64, p = .93) levels of self-compassion. Findings of the present study suggest that low levels of self-compassion may increase risk for alcohol use and experiencing negative alcohol-related consequences in the context of racial discrimination among North American Indigenous adolescents. Future work should examine the utility of interventions targeting self-compassion to examine their effects on responses to racial discrimination and alcohol use.

Diagnosis and Treatment of Alcohol-Associated Liver Disease: A Review

IMPORTANCE

Alcohol-associated liver disease results in cirrhosis in approximately 10% to 20% of patients. In 2017, more than 2 million people had alcohol-associated cirrhosis in the US. Alcohol-associated liver disease is the primary cause of liver-related mortality and the leading indication for liver transplant, representing 40% to 50% of all liver transplant in high-income countries.

OBSERVATIONS

Steatosis, alcoholic hepatitis, and fibrosis are the 3 pathologic findings that are associated with progression to cirrhosis, with highest risk in patients with alcoholic hepatitis. The amount and duration of alcohol consumption, female sex, obesity, and specific genetic polymorphisms such as patatin-like phospholipase domain protein 3, membrane bound O-acyltransferase, and transmembrane 6 superfamily member 2 genes are risk factors for alcohol-associated liver disease progression. Ten-year survival of patients with alcohol-associated liver disease is 88% among those who are abstinent and 73% for those who relapse to alcohol consumption. Symptomatic alcoholic hepatitis is characterized by rapid onset of jaundice and a 30% risk of mortality 1 year after diagnosis. Severe alcoholic hepatitis, defined as a modified discriminant function score greater than or equal to 32 or Model for End-Stage Liver Disease score (starts at 6 and capped at 40; worst = 40) greater than 20, is associated with the development of acute-on-chronic liver failure and multiorgan failure. Corticosteroid therapy is associated with improved 1-month survival from 65% in untreated patients to 80% in treated patients. Early liver transplant may be appropriate in highly select patients with severe alcoholic hepatitis who do not respond to medical therapy. In patients with decompensated cirrhosis, liver transplant should be considered if the Model for End-Stage Liver Disease score remains greater than 17 after 3 months of alcohol abstinence. Between 2014 and 2019, the proportion of patients waiting for liver transplantation who had alcohol-associated liver disease increased from 22% to 40%. Alcohol-associated cirrhosis accounted for approximately 27% of 1.32 million deaths worldwide related to cirrhosis in 2017.

CONCLUSIONS AND RELEVANCE

Alcohol-associated liver disease is among the most common liver diseases and more than 2 million people in the US in 2017 had alcohol-associated cirrhosis. Corticosteroid therapy improves survival in select patients with severe alcoholic hepatitis. Liver transplantation is the most effective therapy in patients with decompensated liver disease.

Alcohol testing and alcohol involvement among violent deaths by state, 2014-2016

Blood alcohol concentration (BAC) testing rates vary across states, potentially biasing estimates of alcohol involvement in violent deaths. The National Violent Death Reporting System (NVDRS) collects information on violent deaths, including decedents' BACs. This study assessed characteristics of violent deaths by BAC testing status, and the proportion of decedents with a positive BAC or BAC ≥ 0.08 g/dL. NVDRS data from 2014 to 2016 (2014: 18 states; 2015: 27 states; 2016: 32 states) were analyzed to assess BAC testing (tested, not tested, unknown/missing) by state, decedent characteristics, and death investigation system (e.g., state medical examiner, coroners), in 2019. The proportion of violent deaths with a BAC > 0.0 or ≥ 0.08 g/dL was also assessed. Among 95,390 violent death decedents, 57.1% had a BAC test (range: 9.5% in Georgia to 95.8% in Utah), 2.3% were not tested, and 40.6% had an unknown/missing BAC testing status (range: 1.3% in Alaska to 78.0% in Georgia). Decedents who were 21-44 years, American Indian/Alaska Native or Hispanic, died by poisoning, died by undetermined intent, or were investigated by a state medical examiner were most likely to receive BAC testing. Among the violent deaths with a reported BAC, 41.1% had a positive BAC and 27.7% had a BAC ≥ 0.08 g/dL. About 2 in 5 violent deaths were missing data on alcohol testing. Increased testing and reporting of alcohol among violent deaths could inform the development and use of evidence-based prevention strategies (e.g., increasing alcohol taxes, regulating alcohol outlet density) for reducing violent deaths.

Assessing the Predictive Validity of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) in Alaska Native and American Indian People

OBJECTIVES

The objective of this study was to examine the predictive validity of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) among Alaska Native and American Indian (ANAI) people with an alcohol use disorder.

METHODS

The sample was 170 ANAI adults with an alcohol use disorder living in Anchorage, Alaska who were part of a larger alcohol intervention study. The primary outcome of this study was alcohol use as measured by mean urinary ethyl glucuronide (EtG). EtG urine tests were collected at baseline and then up to twice a week for four weeks. We conducted bivariate linear regression analyses to evaluate associations between mean EtG value and each of the three SOCRATES subscales (Recognition, Ambivalence, and Taking Steps) and other covariates such as demographic characteristics, alcohol use history, and chemical dependency service utilization. We then performed multivariable linear regression modeling to examine these associations after adjusting for covariates.

RESULTS

After adjusting for covariates, mean EtG values were negatively associated with the Taking Steps (P = 0.017) and Recognition (P = 0.005) subscales of the SOCRATES among ANAI people living in Alaska. We did not find an association between mean EtG values and the Ambivalence subscale (P = 0.129) of the SOCRATES after adjusting for covariates.

CONCLUSIONS

Higher scores on the Taking Steps and Recognition subscales of the SOCRATES at baseline among ANAI people predicted lower mean EtG values. This study has important implications for communities and clinicians who need tools to assist ANAI clients in initiating behavior changes related to alcohol use.

Effect of Incentives for Alcohol Abstinence in Partnership With 3 American Indian and Alaska Native Communities: A Randomized Clinical Trial

Importance

Many American Indian and Alaska Native communities are disproportionately affected by problems with alcohol use and seek culturally appropriate and effective interventions for individuals with alcohol use disorders.

Objective

To determine whether a culturally tailored contingency management intervention, in which incentives were offered for biologically verified alcohol abstinence, resulted in increased abstinence among American Indian and Alaska Native adults. This study hypothesized that adults assigned to receive a contingency management intervention would have higher levels of alcohol abstinence than those assigned to the control condition.

Design, Setting, and Participants

This multisite randomized clinical trial, the Helping Our Native Ongoing Recovery (HONOR) study, included a 1-month observation period before randomization and a 3-month intervention period. The study was conducted at 3 American Indian and Alaska Native health care organizations located in Alaska, the Pacific Northwest, and the Northern Plains from October 10, 2014, to September 2, 2019. Recruitment occurred between October 10, 2014, and February 20, 2019. Eligible participants were American Indian or Alaska Native adults who had 1 or more days of high alcohol-use episodes within the last 30 days and a current diagnosis of alcohol dependence. Data were analyzed from February 1 to April 29, 2020.

Interventions

Participants received treatment as usual and were randomized to either the contingency management group, in which individuals received 12 weeks of incentives for submitting a urine sample indicating alcohol abstinence, or the control group, in which individuals received 12 weeks of incentives for submitting a urine sample without the requirement of alcohol abstinence. Regression models fit with generalized estimating equations were used to assess differences in abstinence during the intervention period.

Main Outcomes and Measures

Alcohol-negative ethyl glucuronide (EtG) urine test result (defined as EtG<150 ng/mL).

Results

Among 1003 adults screened for eligibility, 400 individuals met the initial criteria. Of those, 158 individuals (39.5%; mean [SD] age, 42.1 [11.4] years; 83 men [52.5%]) met the criteria for randomization, which required submission of 4 or more urine samples and 1 alcohol-positive urine test result during the observation period before randomization. A total of 75 participants (47.5%) were randomized to the contingency management group, and 83 participants (52.5%) were randomized to the control group. At 16 weeks, the number who submitted an alcohol-negative urine sample was 19 (59.4%) in the intervention group vs 18 (38.3%) in the control group. Participants randomized to the contingency management group had a higher likelihood of submitting an alcohol-negative urine sample (averaged over time) compared with those randomized to the control group (odds ratio, 1.70; 95% CI, 1.05-2.76; P = .03).

Conclusions and Relevance

The study's findings indicate that contingency management may be an effective strategy for increasing alcohol abstinence and a tool that can be used by American Indian and Alaska Native communities for the treatment of individuals with alcohol use disorders.

Alcohol- and drug-related consequences across latent classes of substance use among American Indian adolescents

INTRODUCTION

Substance use among American Indian (AI) adolescents is a significant public health concern, as they report greater health disparities related to substance use compared to other racial/ethnic groups. The present study examines differences across classes of substance use behaviors regarding alcohol- and drug-related consequences.

METHODS

The current study was a secondary analysis of the dataset used by Stanley and Swaim (2018). AI adolescents (n = 3498, 47.8% female, M_age = 14.8) completed a survey including substance use and related consequences. Protocols were approved by institutional IRB, tribal authority, school boards, and parental consent/child assent were obtained.

RESULTS

In line with Stanley and Swaim (2018), we identified four classes of substance use: no past month substance use; marijuana and cigarette use only; alcohol, marijuana, and cigarette use only; and polysubstance use. Cross-class comparisons revealed that adolescents in classes characterized by the use of a greater number of substances also reported experiencing greater alcohol- and drug-related consequences with one exception: the class characterized by marijuana and cigarette use reported greater drug-related consequences compared to the class characterized by alcohol, marijuana, and cigarette use.

CONCLUSIONS

AI adolescents who engage in the use of multiple substances should be provided with psychoeducation around the increased risk of associated negative consequences. Given the health disparity experienced by AI adolescents, interventions to alleviate the burden of negative consequences are necessary.

Valuing Cultural Activities Moderating the Association Between Alcohol Expectancies and Alcohol Use Among First Nation Adolescents

OBJECTIVE

Indigenous youth often exhibit high rates of alcohol use and experience disproportionate alcohol-related harm. We examined the moderating role that valuing cultural activities has on the relationship between positive alcohol expectancies and alcohol use and heavy drinking in a sample of Indigenous youth.

METHOD

First Nation adolescents between ages 11 and 18 living on a reserve in eastern Canada (N = 106; mean age = 14.6; 50.0% female) completed a pencil-and-paper survey regarding their positive alcohol expectancies, alcohol use, and beliefs about the importance of cultural activities.

RESULTS

A significant interaction was identified between positive alcohol expectancies and valuing cultural activities on past-3-month alcohol use (b = -0.01, SE = 0.001, p < .001) and past-3-month heavy drinking (b = -0.01, SE = 0.001, p < .001). Simple slopes analysis revealed that the association between positive alcohol expectancies and past-3-month alcohol use and heavy drinking was significant for those with low (b = 0.06, SE = 0.007, p < .001; b = 0.07, SE = 0.008, p < .001; respectively) but not high levels of valuing cultural activities (b = 0.01, SE = 0.008, p = .12; b = 0.01, SE = 0.009, p = .08; respectively).

CONCLUSIONS

Highly valuing cultural activities may interrupt the relationship between positive alcohol expectancies and alcohol use. This suggests that community interventions and treatment programs targeting alcohol use among Indigenous adolescents should prioritize increasing the value of cultural activities by perhaps making them more available.

Racial and ethnic differences in alcohol-, opioid-, and co-use-related deaths in Washington State from 2011 to 2017

BACKGROUND

Few studies exist examining alcohol and opioid co-use mortality rates among racially and ethnically diverse communities, presenting a critical gap in understanding the contribution of alcohol on opioid-related deaths and strategies for prevention. The purpose of the study was to assess whether alcohol and opioid-related deaths differ by race/ethnicity subgroups and if there has been an increase in alcohol and opioid-related deaths between 2011 and 2017.

DESIGN

Secondary data analysis of publicly available alcohol and opioid mortality data among non-Hispanic Whites, Black, Hispanic, Asian/Pacific Islander, and American Indian/Alaska Native individuals in Washington State.

MEASUREMENTS

The primary outcomes were alcohol-only, opioid-only, and alcohol-opioid co-use mortality, 2011-2017. Alcohol and/or opioid-related deaths were assigned an International Statistical Classification of Diseases and Related Health Problems (ICD-10) code for the underlying or multiple cause of death.

FINDINGS

Between 2011 and 2017, alcohol-only mortality rates increased among non-Hispanic White (P = 0.003) and Hispanic individuals (P = 0.008). Opioid-only mortality rates increased among American Indian/Alaska Native (P = 0.004) and Hispanic individuals (P = <0.001). American Indian/Alaska Native individuals had the highest alcohol-only, opioid-only, and co-use-related mortality rates when looking at between-group incidence rates.

CONCLUSIONS

Although the opioid epidemic has been characterized as a public health crisis that predominantly impacts non-Hispanic White individuals, racial and ethnic minorities are increasingly impacted by fatal and non-fatal overdose related to co-occurring substance use. Our findings using data from Washington State, align with existing data and signal a dire need to address alcohol and opioid misuse through targeted interventions to prevent overdose and poisoning, with special considerations for American Indian/Alaska Native communities.

The rewarding recovery study: a randomized controlled trial of incentives for alcohol and drug abstinence with a rural American Indian community

AIMS

To test if contingency management (CM) interventions for alcohol and drug abstinence were associated with increased alcohol and drug abstinence among American Indian adults with alcohol dependence who also use drugs.

DESIGN

In this 2 × 2 factorial randomized controlled trial, American Indian adults with alcohol dependence who also used drugs were randomized to four conditions: (1) incentives for submission of urine samples only (control condition), (2) CM incentives for alcohol abstinence, (3) CM incentives for drug abstinence or (4) CM incentives for abstinence from both alcohol and drugs.

SETTING

A Northern Plains Reservation in the United States.

PARTICIPANTS

A total of 114 American Indian adults aged 35.8 years (standard deviation = 10.4); 49.1% were male.

INTERVENTION AND COMPARATOR

Participants received incentives if they demonstrated abstinence from alcohol (CM for alcohol, n = 30), abstinence from their most frequently used drug (CM for drugs, n = 27) or abstinence from both alcohol and their most frequently used drug (CM for alcohol and drugs, n = 32) as assessed by urine tests. Controls (n = 25) received incentives for submitting urine samples only.

MEASUREMENTS

Primary outcomes were urine ethyl glucuronide (alcohol) and drug tests conducted three times per week during the 12-week intervention period. Data analyses included listwise deletion and multiple imputation to account for missing data.

FINDINGS

The three CM groups were significantly (P < 0.05) more likely to submit alcohol-abstinent urine samples compared with the control condition, with odds ratios ranging from 2.4 to 4.8. The CM for drugs (OR = 3.2) and CM for alcohol and drugs (OR = 2.5) were significantly more likely to submit urine samples that indicated drug abstinence, relative to the control condition (P < 0.05). However, these differences were not significant in multiple imputation analyses (P > 0.05).

CONCLUSIONS

Contingency management (CM) incentives for abstinence were associated with increased alcohol abstinence in American Indian adults diagnosed with alcohol dependence who also used drugs, living on a rural reservation. The effect of CM incentives on drug abstinence was inconclusive.

Perceptions of alcohol misuse among Alaska native health care system stakeholders: A qualitative exploration

Although alcohol misuse is a priority for health care systems serving Alaska Native and American Indian (ANAI) people, stakeholders' perceptions of misuse are understudied. Patients (n = 34), providers (n = 20), and leaders (n = 16) at a Tribally owned and operated health care system reported that alcohol misuse results from the interaction of factors, including colonization, structural factors, social alienation, social norms about overdrinking introduced at the time of colonizing contact, coping with emotions, and beliefs about ANAI people and alcohol. Childhood exposure to alcohol misuse leads some ANAI people to avoid alcohol altogether, shedding light on the high levels of abstinence observed in ANAI communities.

Health disparities in American Indians/Alaska Natives: Implications for nurse practitioners

American Indians/Alaska Natives experience significant health disparities in many areas including metabolic and mental health disorders. The basis for these differences is grounded in the lasting effects of historical trauma. NPs have the opportunity to understand the underlying causes of these disparities and provide health interventions that promote wellness.

Evaluating the Validity of the DSM-5 Alcohol Use Disorder Diagnostic Criteria in a Sample of Treatment-seeking Native Americans

OBJECTIVE

Despite high rates of alcohol use disorder (AUD) and alcohol-induced deaths among Native Americans, there has been limited study of the construct validity of the AUD diagnostic criteria. The purpose of the current study was to examine the validity of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) AUD criteria in a treatment-seeking group of Native Americans.

METHODS

As part of a larger study, 79 Native Americans concerned about their alcohol or drug use were recruited from a substance use treatment agency located on a reservation in the southwestern United States. Participants were administered the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (SCID for DSM-IV-TR) reworded to assess 11 DSM-5 criteria for AUD. Confirmatory factor analysis (CFA) was used to test the validity of the AUD diagnostic criteria, and item response theory (IRT) was used to examine the item characteristics of the AUD diagnostic criteria in this Native American sample.

RESULTS

CFA indicated that a 1-factor model of the 11 items provided a good fit of the data. IRT parameter estimates suggested that "withdrawal," "social/interpersonal problems," and "activities given up to use" had the highest magnitude of discrimination. "Much time spent using" and "activities given up to use" were associated with the greatest severity.

CONCLUSIONS

The current study provided support for the validity of the AUD DSM-5 criteria and a unidimensional latent construct of AUD in this sample of treatment-seeking Native Americans. IRT analyses replicate findings from previous studies. To our knowledge, this is the first study to examine the validity of the DSM-5 AUD criteria in a treatment-seeking sample of Native Americans. Continued research in other Native American samples is needed.

Call to Action: Rural Health: A Presidential Advisory From the American Heart Association and American Stroke Association

Understanding and addressing the unique health needs of people residing in rural America is critical to the American Heart Association's pursuit of a world with longer, healthier lives. Improving the health of rural populations is consistent with the American Heart Association's commitment to health equity and its focus on social determinants of health to reduce and ideally to eliminate health disparities. This presidential advisory serves as a call to action for the American Heart Association and other stakeholders to make rural populations a priority in programming, research, and policy. This advisory first summarizes existing data on rural populations, communities, and health outcomes; explores 3 major groups of factors underlying urban-rural disparities in health outcomes, including individual factors, social determinants of health, and health delivery system factors; and then proposes a set of solutions spanning health system innovation, policy, and research aimed at improving rural health.

Incidence, deaths, and lifetime costs of injury among American Indians and Alaska Natives

BACKGROUND

In the United States, the mortality burden of injury is higher among American Indians and Alaska Natives (AI/AN) than any other racial/ethnic group, and injury contributes to considerable medical costs, years of potential life lost (YPLL), and productivity loss among AI/AN.This study assessed the economic burden of injuries for AI/AN who are eligible for services through Indian Health Service, analyzing direct medical costs of injury for Indian Health Service's users and years of potential life lost (YPLL) and the value of productivity losses from injury deaths for AI/AN in the Indian Health Service population.

METHODS

Injury-related lifetime medical costs were estimated for Indian Health Service users with medically treated injuries using data from the 2011-2015 National Data Warehouse. Productivity costs and YPLL were estimated using data on injury-related deaths among AI/AN in Indian Health Service's 2008-2010 service population. Costs were reported in 2017 U.S. dollars.

RESULTS

The total estimated costs of injuries per year, including injuries among Indian Health Service users and productivity losses from injury-related deaths, were estimated at $4.5 billion. Lifetime medical costs to treat annual injuries among Indian Health Service users were estimated at $549 million, with the largest share ($131 million) going toward falls, the most frequent injury cause. Total estimated YPLL from AI/AN injury deaths in Indian Health Service's service population were 106,400. YPLL from injury deaths for men (74,000) were 2.2 times YPLL for women (33,000). Productivity losses from all injury-related deaths were $3.9 billion per year. The highest combined lifetime medical and mortality costs were for motor vehicle/traffic injuries, with an estimated cost of $1.6 billion per year.

CONCLUSIONS

Findings suggest that targeted injury prevention efforts by Indian Health Service likely contributed to lower rates of injury among AI/AN, particularly for motor vehicle/traffic injuries. However, because of remaining disparities in injury-related outcomes between AI/AN and all races in the United States, Indian Health Service should continue to monitor changes in injury incidence and costs over time, evaluate the impacts of previous injury prevention investments on current incidence and costs, and identify additional injury prevention investment needs.

Genetic and Epigenetic Modifiers of Alcoholic Liver Disease

Alcoholic liver disease (ALD), a disorder caused by excessive alcohol consumption is a global health issue. More than two billion people consume alcohol in the world and about 75 million are classified as having alcohol disorders. ALD embraces a wide spectrum of hepatic lesions including steatosis, alcoholic steatohepatitis (ASH), fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). ALD is a complex disease where environmental, genetic, and epigenetic factors contribute to its pathogenesis and progression. The severity of alcohol-induced liver disease depends on the amount, method of usage and duration of alcohol consumption as well as on age, gender, presence of obesity, and genetic susceptibility. Genome-wide association studies and candidate gene studies have identified genetic modifiers of ALD that can be exploited as non-invasive biomarkers, but which do not completely explain the phenotypic variability. Indeed, ALD development and progression is also modulated by epigenetic factors. The premise of this review is to discuss the role of genetic variants and epigenetic modifications, with particular attention being paid to microRNAs, as pathogenic markers, risk predictors, and therapeutic targets in ALD.

Disproportionately higher unintentional injury mortality among Alaska Native people, 2006-2015

We compared rates of unintentional injury (UI) deaths (total and by injury category) among Alaska Native (AN) people to rates of U.S. White (USW) and Alaska White (AKW) populations during 2006-2015. The mortality data for AN and AKW populations were obtained from Alaska Bureau of Vital Statistics and USW mortality data were obtained from WISQARS, the Center for Disease Control and Prevention online injury data program. AN and AKW rates were age-adjusted to the U.S. 2000 Standard Population and rate ratios (RR) were calculated. AN people had higher age-adjusted total UI mortality than the USW (RR = 2.6) and AKW (RR = 2.3) populations. Poisoning was the leading cause of UI death among AN people (35.9 per 100,000), more than twice that of USW (RR = 2.9) and AKW (RR = 2.5). Even greater disparities were found between AN people and USW for: natural environment (RR = 20.7), transport-other land (RR = 12.4), and drowning/submersion (RR = 9.1). Rates of AN UI were markedly higher than rates for either USW or AKW. Identifying all the ways in which alcohol/drugs contribute to UI deaths would aid in prevention efforts. All transportation deaths should be integrated into one fatality rate to provide more consistent comparisons between groups.

Incidence of primary liver cancer in American Indians and Alaska Natives, US, 1999-2009

PURPOSE

To evaluate liver cancer incidence rates and risk factor correlations in non-Hispanic AI/AN populations for the years 1999-2009.

METHODS

We linked data from 51 central cancer registries with the Indian Health Service patient registration databases to improve identification of the AI/AN population. Analyses were restricted to non-Hispanic persons living in Contract Health Service Delivery Area counties. We compared age-adjusted liver cancer incidence rates (per 100,000) for AI/AN to white populations using rate ratios. Annual percent changes (APCs) and trends were estimated using joinpoint regression analyses. We evaluated correlations between regional liver cancer incidence rates and risk factors using Pearson correlation coefficients.

RESULTS

AI/AN persons had higher liver cancer incidence rates than whites overall (11.5 versus 4.8, RR = 2.4, 95% CI 2.3-2.6). Rate ratios ranged from 1.6 (Southwest) to 3.4 (Northern Plains and Alaska). We observed an increasing trend among AI/AN persons (APC 1999-2009 = 5%). Rates of distant disease were higher in the AI/AN versus white population for all regions except Alaska. Alcohol use (r = 0.84) and obesity (r = 0.79) were correlated with liver cancer incidence by region.

CONCLUSIONS

Findings highlight disparities in liver cancer incidence between AI/AN and white populations and emphasize opportunities to decrease liver cancer risk factor prevalence.

Characterizing a Hidden Group of At-Risk Drinkers: Epidemiological Profiles of Alcohol-Use Disorder Diagnostic Orphans

BACKGROUND

Drinkers who report some symptoms of alcohol-use disorder (AUD) but fail to meet full criteria are "diagnostic orphans." To improve risk-reduction efforts, we sought to develop better epidemiologic profiles of this underrecognized subgroup.

METHODS

This study estimated the population prevalence and described AUD symptoms of diagnostic orphans using the 2012-2013 National Epidemiological Survey of Alcohol and Related Conditions-III. Multivariate logistic regression was used to model odds of being a diagnostic orphan or meeting mild, moderate, and severe AUD criteria versus no AUD symptoms. Models were adjusted for the complex survey design using sampling weights and survey procedures (e.g., proc surveylogistic).

RESULTS

Among drinkers, 14% of men and 11% of women were classified as diagnostic orphans. The most common symptoms were drinking more or for longer periods than intended, wanting or trying unsuccessfully to quit or cut back, and drinking in ways that increased risk of injury. We noted broad similarities between diagnostic orphans and mild/moderate AUD groups. There were no differences in odds of diagnostic orphans status by race/ethnicity; however, female gender was associated with lower odds of diagnostic orphan status and all levels of AUD. Individual history of AUD, family history of problem drinking, concurrent smoking, and concurrent marijuana use were associated with greater odds of problem drinking, with stronger associations as AUD severity increased.

CONCLUSIONS

Diagnostic orphans remain a sizeable and overlooked population of problem drinkers. Clarifying the array of symptoms and cooccurring disorders can improve screening and facilitate alcohol risk-reduction intervention efforts.

"Improving Native American elder access to and use of health care through effective health system navigation"

BACKGROUND

Public insurance reforms of the past two decades have failed to substantively address the healthcare needs of American Indians in general, let alone the particular needs of American Indian elders, ages 55 years and older. Historically, this population is more likely to be uninsured and to suffer from greater morbidities, poorer health outcomes and quality of life, and lower life expectancies compared to all other United States aging populations, representing a neglected group within the healthcare system. Despite the pervasive belief that the Indian Health Service will address all their health-related needs, American Indian elders are negatively affected by gaps in insurance and lack of access to health care. While the 2010 Patient Protection and Affordable Care Act included provisions to ameliorate disparities for American Indians, its future is uncertain. In this context, American Indian elders with variable health literacy must navigate a complex and unstable healthcare system, regardless of where they seek care.

METHODS

This community-driven study features a mixed-method, participatory design to examine help-seeking behavior and healthcare experiences of American Indian elders in New Mexico, in order to develop and evaluate a tailored intervention to enhance knowledge of, access to, and use of insurance and available services to reduce healthcare disparities. This study includes qualitative and quantitative interviews combined with concept mapping and focus groups with American Indian elders and other key stakeholders.

DISCUSSION

The information gathered will generate new practical knowledge, grounded in actual perspectives of American Indian elders and other relevant stakeholders, to improve healthcare practices and policies for a population that has been largely excluded from national and state discussions of healthcare reform. Study data will inform development and evaluation of culturally tailored programming to enhance understanding and facilitate negotiation of the changing landscape of health care by American Indian elders. This work will fill a gap in research on public insurance initiatives, which do not typically focus on this population, and will offer a replicable model for enhancing the effects of such initiatives on other underserved groups affected by healthcare inequities.

Substance Use Among American Indian Youths on Reservations Compared With a National Sample of US Adolescents

IMPORTANCE

American Indian adolescents attending schools on or near reservations are historically at high risk for substance use.

OBJECTIVE

To compare rates of substance use among reservation-based American Indian adolescents vs rates among national US youths.

DESIGN, SETTING, AND PARTICIPANTS

Population-based survey study of 8th-, 10th-, and 12th-grade students attending participating schools on or near reservations, stratified by region, during the 2016-2017 school year. Substance use rates were compared with those of a national sample of comparably aged students from the Monitoring the Future study.

MAIN OUTCOMES AND MEASURES

Lifetime and last-30-day self-reported use of alcohol, marijuana, and other drugs, using relative risk (RR) ratios with 95% confidence intervals to compare American Indian student rates with Monitoring the Future student rates.

RESULTS

Participants included 570 students in eighth grade (49.6% girls; mean age, 13.5 years), 582 in 10th grade (50.0% girls; mean age, 15.4 years), and 508 in 12th grade (53.5% girls; mean age, 17.4 years). American Indian students reported substantially higher lifetime and last-30-day substance use rates compared with the Monitoring the Future students, with greatest disparity at eighth grade: last-30-day substance use RRs for grade 8 were 2.1 (95% CI, 1.4-3.0) for alcohol, 4.2 (95% CI, 3.1-5.8) for marijuana, and 2.4 (95% CI, 1.7-3.3) for other illicit drugs. Compared with 2009 to 2012 data, the RRs between American Indian and Monitoring the Future students for lifetime alcohol and marijuana use did not change substantially from the 2016-2017 school year (alcohol: RR, 1.5 [95% CI, 1.4-1.6] vs RR, 1.3 [95% CI, 1.2-1.4], respectively; marijuana: RR, 2.0 [95% CI, 1.8-2.1] vs RR, 2.1 [95% CI, 1.9-2.3], respectively), but increased substantially for other drugs (RR, 1.8 [95% CI, 1.7-1.9] vs RR, 3.0 [95% CI, 2.9-3.2], respectively).

CONCLUSIONS AND RELEVANCE

Reservation-based American Indian students are at high risk for substance use compared with US youths in general, making prevention efforts critical. Cultural and value-based characteristics unique to American Indian populations may provide beneficial targets for prevention, but there is limited evidence on how cultural factors work to prevent risky behaviors. Without increased attention to these disparities, the costs to American Indian youths and their communities will remain high.
