Suicidality by Sexual Identity and Correlates Among American Indian and Alaska Native High School Students. J Adolesc Health 2023; 73:1030-1037. [PMID: 37737757 PMCID: PMC10840863 DOI: 10.1016/j.jadohealth.2023.07.020] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2022] [Revised: 07/04/2023] [Accepted: 07/12/2023] [Indexed: 09/23/2023]
Abstract
PURPOSE This study aims to determine the prevalence of suicidality among American Indian and Alaskan Native (AI/AN) adolescents. Additionally, we measured suicidality, stratified by sex, and its association with sexual identity, sexual violence, and binge drinking. METHODS We pooled data from the Youth Risk Behavior Survey from 2005 to 2019 to analyze the prevalence of sexual minorities, forced sex, and binge drinking, and their association with suicidality using basic descriptive statistics followed by adjusted odds ratios stratified by sex among AI/AN youth. RESULTS 19% of AI/AN participants reported having suicidal thoughts and 14% reported having a previous suicide attempt. More than 17% of AI/AN participants identified as sexual minority youth (SMY). Compared to AI/AN heterosexual youth, AI/AN bisexual youth had significantly higher odds of reporting suicidal thoughts (aOR = 16.01), planning (aOR = 12.4), and previous attempts (aOR = 7.73). This pattern was also significantly demonstrated for AI/AN gay/lesbian youth. 43% of all AI/AN participants reported being forced into sexual intercourse. The presence of binge drinking was associated with higher odds of suicidal thoughts for both females and males compared to those who did not binge drink. DISCUSSION At the intersection of multiple marginalization, AI/AN SMY have a high mental health burden, demonstrating the need for culturally informed, community-led, and targeted mental health support focused on SMY AI/AN. Though this study fails to capture the heterogeneity within the AI/AN community, as nuances exist at the tribal level, these results demonstrate work needs to be done to support the health burden that AI/AN youth carry.

Abstract
AIMS This study explored the relationship between social support, community connections, self-esteem, and culture on misuse in American Indian youth. METHODS The study team developed a culturally-responsive 16-question survey for American Indian youth ages 12-20 living in six American Indian communities in the Great Plains Region of the United States. The study was grounded in primary socialization theory and variables were explored using regression models. RESULTS A total of 565 American Indian youth completed the participant survey between January 2016 and August 2017. The present study found that community connections were negatively associated with marijuana use in American Indian youth. Higher community connection scores were associated with higher social support and self-esteem scores. CONCLUSIONS Tribally-led prevention initiatives can fill an important socio-behavioral prevention gap by facilitating social support opportunities for American Indian youth who may not have adequate support from immediate family or friends.

Abstract
Use of hallucinogenic substances as a public health concern has increased over the past decade. Among adolescents, there are increasing emergency department presentations for intoxication with these drugs, contrary to decreasing reported use of classical hallucinogens such as LSD. Academic and governmental groups have monitored use of hallucinogens, highlighting a notable change in perceptions about use among adolescents thought to contribute to these trends. Special populations and religious groups, though, have been granted governmental permission to use hallucinogens for their cultural practices. Novel designer hallucinogens have gained popularity and may have serious medical and psychological side effects from use.

Abstract
This study investigated the combined influence of parental monitoring, community monitoring, and exposure to substance-using peers on early-onset alcohol use in a sample of American Indian adolescents in three Pacific Northwest tribal communities. We used structural equation modeling, including tests of indirect effects, in the investigation of 281 American Indian youth between ages 8 and 16 years at the time of consent. The effects of parental monitoring and community monitoring, mediated by friends' substance use, were examined in terms of youth alcohol use outcomes. Parental monitoring practices and contagion in peer substance use were proximal predictors of early-onset alcohol use and the mediating effect of friends' substance use was not significant. Community monitoring accounted for unique variance in affiliation with substance-using friends.

Abstract
High rates of substance use and related problems have been long recognized as critical health issues for Native American adolescents. Unfortunately, no manualized interventions address the specific needs of Native American adolescents in a culturally appropriate manner. In 2006, the Cherokee Nation partnered with the University of Colorado to employ a community-based participatory research process to develop an intervention for Native American adolescents with substance use problems. The resulting intervention, Walking On, is an explicit blend of traditional Cherokee healing and spirituality with science-based practices such as cognitive behavioral therapy and contingency management and is designed to address the specific needs and worldviews of Native American adolescents with substance use problems and their families. Each individual and family session includes a brief assessment, a skill-building component, and a ceremony. A Weekly Circle (multifamily group) promotes sobriety and builds a community of healing. Early pilot study results suggest that Walking On is feasible for use in tribal substance abuse treatment programs. While Walking On shows early promise, the intervention will require further study to examine its efficacy.

Abstract
CONTEXT Substance use disorders (SUD) are a major public health problem. Attention deficit hyperactivity disorder (ADHD) is a comorbid condition associated with both onset and prognosis of SUD. Prevalence estimates of ADHD in SUD vary significantly. OBJECTIVE To obtain a best estimate of the prevalence of ADHD in SUD populations. DATA SOURCES A literature search was conducted using MEDLINE, PsycINFO and EMBASE. Search terms were ADHD, substance-related disorders, addiction, drug abuse, drug dependence, alcohol abuse, alcoholism, comorbidity, and prevalence. Results were limited to the English language. STUDY SELECTION After assessing the quality of the retrieved studies, 29 studies were selected. Studies in which nicotine was the primary drug of abuse were not included. DATA EXTRACTION All relevant data were extracted and analysed in a meta-analysis. A series of meta-regression analyses was performed to evaluate the effect of age, primary substance of abuse, setting and assessment procedure on the prevalence of ADHD in a variety of SUD populations. DATA SYNTHESIS Overall, 23.1% (CI: 19.4-27.2%) of all SUD subjects met DSM-criteria for comorbid ADHD. Cocaine dependence was associated with lower ADHD prevalence than alcohol dependence, opioid dependence and other addictions. Studies using the DICA or the SADS-L for the diagnosis of ADHD showed significantly higher comorbidity rates than studies using the KSADS, DISC, DIS or other assessment instruments. CONCLUSIONS ADHD is present in almost one out of every four patients with SUD. The prevalence estimate is dependent on substance of abuse and assessment instrument.

Pathways to care: narratives of American Indian adolescents entering substance abuse treatment. Soc Sci Med 2012; 74:2037-45.

Abstract
Using data from 89 American Indian adolescents and guided by the Network Episode Model, this paper analyses pathways to residential substance abuse treatment and their correlates. These adolescents were recruited at admission to a tribally-operated substance abuse treatment program in the southern United States from October 1998 to May 2001. Results from the qualitative analyses of these adolescent's pathways to care narratives indicated that 35% ultimately agreed with the decision for their entry into treatment; 41% were Compelled to enter treatment by others, usually by their parents, parole officers, and judges; and 24% did not describe a clear pathway to care. In the multinomial logistic regression model examining correlates of these pathways to care classifications, adolescents who described pathways indicative of agreement also reported greater readiness for treatment than the adolescents who described compelled or no clear pathways to care. Adolescents who described a Compelled pathway were less likely to meet diagnostic criteria for Conduct Disorder and described fewer social network ties. We were unable to find a relationship between pathways classifications and referral source, suggesting these narratives were subjective constructions of pathways to care rather than a factual representation of this process. In the final logistic regression model examining correlates of treatment completion, articulating a pathway to care, whether it was one of agreement or of being compelled into treatment, predicted a greater likelihood of completing treatment. Overall, these narratives and their correlates are highly consistent with the Network-Episode Model's emphasis on the interaction of self, situation, and social network in shaping the treatment seeking process, demonstrating the applicability of this model to understanding the treatment seeking process in this special population and suggests important considerations for understanding the dynamics of service utilization across diverse communities.

Abstract
CONTEXT While young racial/ethnic groups are the fastest growing population in the United States, data about substance-related disorders among adolescents of various racial/ethnic backgrounds are lacking. OBJECTIVE To examine the magnitude of past-year DSM-IV substance-related disorders (alcohol, marijuana, cocaine, inhalants, hallucinogens, heroin, analgesic opioids, stimulants, sedatives, and tranquilizers) among adolescents of white, Hispanic, African American, Native American, Asian or Pacific Islander, and multiple race/ethnicity. DESIGN The 2005 to 2008 National Survey on Drug Use and Health. SETTING Academic research. PARTICIPANTS Noninstitutionalized household adolescents aged 12 to 17 years. MAIN OUTCOME MEASURES Substance-related disorders were assessed by standardized survey questions administered using the audio computer-assisted self-interviewing method. RESULTS Of 72 561 adolescents aged 12 to 17 years, 37.0% used alcohol or drugs in the past year; 7.9% met criteria for a substance-related disorder, with Native Americans having the highest prevalence of use (47.5%) and disorder (15.0%). Analgesic opioids were the second most commonly used illegal drugs, following marijuana, in all racial/ethnic groups; analgesic opioid use was comparatively prevalent among adolescents of Native American (9.7%) and multiple race/ethnicity (8.8%). Among 27 705 past-year alcohol or drug users, Native Americans (31.5%), adolescents of multiple race/ethnicity (25.2%), adolescents of white race/ethnicity (22.9%), and Hispanics (21.0%) had the highest rates of substance-related disorders. Adolescents used marijuana more frequently than alcohol or other drugs, and 25.9% of marijuana users met criteria for marijuana abuse or dependence. After controlling for adolescents' age, socioeconomic variables, population density of residence, self-rated health, and survey year, adjusted analyses of adolescent substance users indicated elevated odds of substance-related disorders among Native Americans, adolescents of multiple race/ethnicity, adolescents of white race/ethnicity, and Hispanics compared with African Americans; African Americans did not differ from Asians or Pacific Islanders. CONCLUSIONS Substance use is widespread among adolescents of Native American, white, Hispanic, and multiple race/ethnicity. These groups also are disproportionately affected by substance-related disorders.

Abstract
As descendants of the indigenous peoples of the United States, American Indians and Alaska Natives (AI/ANs) have experienced a resurgence in population and prospects since the beginning of the twentieth century. Today, tribally affiliated individuals number over two million, distributed across 565 federally recognized tribal communities and countless metropolitan and nonreservation rural areas. Although relatively little evidence is available, the existing data suggest that AI/AN adults and youth suffer a disproportionate burden of mental health problems compared with other Americans. Specifically, clear disparities have emerged for AI/AN substance abuse, posttraumatic stress, violence, and suicide. The rapid expansion of mental health services to AI/AN communities has, however, frequently preceded careful consideration of a variety of questions about critical components of such care, such as the service delivery structure itself, clinical treatment processes, and preventive and rehabilitative program evaluation. As a consequence, the mental health needs of these communities have easily outpaced and overwhelmed the federally funded agency designed to serve these populations, with the Indian Health Service remaining chronically understaffed and underfunded such that elimination of AI/AN mental health disparities is only a distant dream. Although research published during the past decade has substantially improved knowledge about AI/AN mental health problems, far fewer investigations have explored treatment efficacy and outcomes among these culturally diverse peoples. In addition to routine calls for greater clinical and research resources, however, AI/AN community members themselves are increasingly advocating for culturally alternative approaches and opportunities to address their mental health needs on their own terms.

Abstract
BACKGROUND A variety of forces are now shaping a passionate debate regarding the optimal approaches to improving the quality of substance abuse services for American Indian and Alaska Native communities. While there have been some highly successful efforts to meld the traditions of American Indian and Alaska Native tribes with that of 12-step approaches, some American Indian and Alaska Natives remain profoundly uncomfortable with the dominance of this Euro-American approach to substance abuse treatment in their communities. This longstanding tension has now been complicated by the emergence of a number of evidence-based treatments that, while holding promise for improving treatment for American Indian and Alaska Natives with substance use problems, may conflict with both American Indian and Alaska Native and 12-step healing traditions. DISCUSSION We convened a panel of experts from American Indian and Alaska Native communities, substance abuse treatment programs serving these communities, and researchers to discuss and analyze these controversies in preparation for a national study of American Indian and Alaska Native substance abuse services. While the panel identified programs that are using evidence-based treatments, members still voiced concerns about the cultural appropriateness of many evidence-based treatments as well as the lack of guidance on how to adapt them for use with American Indians and Alaska Natives. The panel concluded that the efforts of federal and state policymakers to promote the use of evidence-based treatments are further complicating an already-contentious debate within American Indian and Alaska Native communities on how to provide effective substance abuse services. This external pressure to utilize evidence-based treatments is particularly problematic given American Indian and Alaska Native communities' concerns about protecting their sovereign status. SUMMARY Broadening this conversation beyond its primary focus on the use of evidence-based treatments to other salient issues such as building the necessary research evidence (including incorporating American Indian and Alaska Native cultural values into clinical practice) and developing the human and infrastructural resources to support the use of this evidence may be far more effective for advancing efforts to improve substance abuse services for American Indian and Alaska Native communities.

Abstract
This study examined the effects of psychopathological, peer, family, and cultural predictors of American Indian adolescents' drug use following inpatient treatment. Data regarding lifetime, 90 days prior to treatment, and 1-year posttreatment substance use were collected using interviews, questionnaires, and observations of 57 American Indian adolescents and their families. Trajectories of days-used measures were subjected to semiparametric trajectory analysis. Trajectories were then compared on baseline measures by using both univariate and multivariate logit regression techniques. The study sought to identify prerelease predictors of membership in post-inpatient treatment substance use trajectory groups. Findings provide insight into the unique and shared risk and protective factors relevant to American Indian adolescents' substance use outcomes. In particular, this study suggests that a combination of family management and American Indian traditional cultural practices in families serves as a potential target for interventions to reduce substance use in adolescence.

Abstract
American Indian/Alaska Native youth represent the strength and continued survival of many Nations and Tribes. However, they currently experience numerous health disparities and challenges, including the highest rate of suicide among 15-24 year-olds in the United States. Our comprehensive review of the literature on the mental health of AI/AN youth highlighted seven focal causes of behavioral health disparities: (1) high levels of violence and trauma exposure and traumatic loss, (2) past and current oppression, racism, and discrimination, (3) underfunded systems of care, (4) disregard for effective indigenous practices in service provision, policy, and funding, (5) overreliance on evidence-based practices, (6) lack of cultural competence among systems of care and providers, and (7) barriers to care. Seven policy recommendations that recognize the importance of moving beyond exclusive reliance on western models of care and that seek to foster transformation of individuals, families, communities, behavioral health service systems of care, and social structures are presented, supported, and discussed.

Abstract
Alcohol dependence is one of the leading causes of morbidity and mortality in Native Americans. Externalizing disorders such as conduct disorder (CD) and antisocial personality disorder (ASPD) have been demonstrated to have significant comorbidity with alcohol dependence in the general population. This study's aims were to: assess the comorbidity of DSM-III-R ASPD and CD with alcohol dependence, to map susceptibility loci for ASPD and CD, and to see if there is overlap with loci previously mapped for alcohol dependence phenotypes in 587 American Indians. Alcohol dependence was found to be comorbid with DSM-III-R ASPD but not CD. However, the amount of alcohol dependence in the population attributable to ASPD and/or CD is low. ASPD and the combined phenotype of participants with ASPD or CD were both found to have significant heritability, whereas no significant evidence was found for CD alone. Genotypes were determined for a panel of 791 micro-satellite polymorphisms in 251 of the participants. Analyses of multipoint variance component LOD scores, for ASPD and ASPD/CD, revealed six locations that had a LOD score of 2.0 or above: on chromosome 13 for ASPD and on chromosomes 1, 3, 4, 14, 17, and 20 for ASPD/CD. These results corroborate the importance of several chromosomal regions highlighted in prior segregation studies for externalizing diagnoses. These results also further identify new regions of the genome, that do not overlap with alcohol dependence phenotypes previously identified in this population, that may be unique to either the phenotypes evaluated or this population of American Indians.
