No Indians to Spare: Depression and Suicide in Indigenous American Children and Youth

Profiles of suicide attempted in children and adolescents

OBJECTIVE

Suicide attempt (SA) is the strongest predictive variable for completed suicide. The Department of Cauca in Colombia has an SA rate higher than the national average, but the factors are unknown. The objective was to identify the profiles of SA in children and adolescents of Cauca.

METHODS

Cross-sectional study, which included all SA (Event-356) records from the SIVIGILA platform in children under 18 years of age between 2016 and 2019. The authors described the variables and multiple correspondence analysis (MCA) with the Burt method, according to the completeness of the data to establish the possible SA profiles using STATA 15.1, and R. The Ethics Committee at Universidad del Cauca approved it.

RESULTS

The study found 977 SA during this period, 72.4% female, 97.1% adolescent, 74.4% mestizo, 19.3% indigenous, 45.3% resided in municipalities exposed to the armed conflict, 32.3% expressed ideation and previous attempts, and 15.5% prior attempts. The MCA included 810 SA and identified three profiles: "Classic", which had mestizo adolescents with a history of prior SA, mental illness, or psychoactive substance use problems; "Related to the armed conflict", which included female adolescents with a first SA and residents in municipalities exposed to the armed conflict; "Ethnic" represented by male indigenous, with housing in a rural area.

CONCLUSION

The SA profiles found in Cauca were "Classic", "Related to the armed conflict", and "Ethnic"; these can be considered to implement prevention strategies from a cross-cultural, mental health, and gender perspective, with the presence of the state in the territories.

Social zeitgeber and sleep loss as risk factors for suicide in American Indian adolescents

American Indians / Alaska Natives (AI/AN) bear a high burden of suicide, the reasons for which are not completely understood, and rates can vary by tribal group and location. This article aims to identify circumstances reported by a community group of American Indian adolescent participants to be associated with their depression and/or suicide. American Indian adolescents (n  =  360) were recruited from contiguous reservations and were assessed with a semi-structured diagnostic interview. Twenty percent of the adolescents reported suicidal thoughts (ideation, plans), an additional 8% reported a history of suicide attempts, and three deaths due to suicide were reported. Suicidal behaviors and major depressive disorder (MDD) co-occurred and were more common among female adolescents. The distressing events that adolescents most often reported were: death in the family, family disruption, peer relationship problems, and school problems. All of these events were significantly associated with suicidal behaviors, however those with suicidal acts were more likely to report death in the family. Those with MDD but no suicidal behaviors were more likely to report disruptions in the family. Disruptions in falling asleep were also associated with suicidal behaviors and having experienced a death in the family. Disruptions in important relationships, particularly through death or divorce, may be interpreted as a loss or disruption in "social zeitgebers" that may in turn disturb biological rhythms, such as sleep, thus potentially increase the risk for MDD and/or suicide. Prevention programs aimed at ameliorating the impact of disruptions in important relationships may potentially reduce suicidal behaviors in AI/AN adolescents.

Genetic factors associated with suicidal behaviors and alcohol use disorders in an American Indian population

American Indians (AI) demonstrate the highest rates of both suicidal behaviors (SB) and alcohol use disorders (AUD) among all ethnic groups in the US. Rates of suicide and AUD vary substantially between tribal groups and across different geographical regions, underscoring a need to delineate more specific risk and resilience factors. Using data from over 740 AI living within eight contiguous reservations, we assessed genetic risk factors for SB by investigating: (1) possible genetic overlap with AUD, and (2) impacts of rare and low-frequency genomic variants. Suicidal behaviors included lifetime history of suicidal thoughts and acts, including verified suicide deaths, scored using a ranking variable for the SB phenotype (range 0-4). We identified five loci significantly associated with SB and AUD, two of which are intergenic and three intronic on genes AACSP1, ANK1, and FBXO11. Nonsynonymous rare and low-frequency mutations in four genes including SERPINF1 (PEDF), ZNF30, CD34, and SLC5A9, and non-intronic rare and low-frequency mutations in genes OPRD1, HSD17B3 and one lincRNA were significantly associated with SB. One identified pathway related to hypoxia-inducible factor (HIF) regulation, whose 83 nonsynonymous rare and low-frequency variants on 10 genes were significantly linked to SB as well. Four additional genes, and two pathways related to vasopressin-regulated water metabolism and cellular hexose transport, also were strongly associated with SB. This study represents the first investigation of genetic factors for SB in an American Indian population that has high risk for suicide. Our study suggests that bivariate association analysis between comorbid disorders can increase statistical power; and rare and low-frequency variant analysis in a high-risk population enabled by whole-genome sequencing has the potential to identify novel genetic factors. Although such findings may be population specific, rare functional mutations relating to PEDF and HIF regulation align with past reports and suggest a biological mechanism for suicide risk and a potential therapeutic target for intervention.

Suicide in a Colombian indigenous community: Beyond mental illness

BACKGROUND

Among the causes associated with suicide there are social factors such as forced displacement has been described and health factors in general that have an impact on pediatric mental health.

AIMS

To describe clinical and psychosocial factors, and their relationship with suicidal behavior in a Colombian indigenous community.

PARTICIPANTS AND SETTING

The mean age were 9.23 years old, 53.7% male and 46.3% female.

METHOD

Mixed approach study. A thematic analysis was carried out with the youth of the community to investigate emotional aspects. A descriptive cross-sectional study was carried out and correlations between variables were made.

RESULTS

Correlations were found between suicidal behavior and medical findings. When comparing the mental health disorders and nutritional problems, statistically significant differences were found in the Suicide Risk domain (<.001). This was reaffirmed in the thematic analysis, where factors such as migration and difficulty understanding the language are highlighted as related to suicidal behavior in the pediatric population.

CONCLUSIONS

Suicidal behavior should not be approached solely from psychopathology. Hunger, the weakening of one's own culture, armed conflict, migration, and other clinical conditions are found to be associated with suicidal behavior.

Understanding the resilience of children living on an American Indian reservation: A mixed methods participatory study

AIM

To explore the resilience of children, six to thirteen years old, living on a Northern Plains American Indian Reservation using a situation specific nursing theory.

BACKGROUND

American Indian and Alaska Native children experience mental health inequities compared to their white peers, including substance use, suicide, depression, and anxiety. Resilience is a strength of children that can be leveraged to improve their mental health.

DESIGN

A parallel convergent mixed methods design.

METHODS

A community advisory board culturally adapted resilience instruments. During two weeks in summer 2022, forty-seven children/caregiver dyads completed surveys about the child's resilience. Descriptive statistics gave the scores of each child's personal, relational, and total resilience. A subset of 20 children participated in a semi-structured interview.

RESULTS

Children scored high on overall resilience, and higher on the relational subscale than the personal subscale. Caregiver survey scores were not significantly correlated with their child's scores and were higher than the children's scores. Qualitative coding revealed six themes of resilience. Integration of data showed a concordance and expansion of the quantitative data across themes.

CONCLUSION

The children reported high resilience supported by a strong ecosystem of relationships. Resilience, as explained through children's voices, corroborated with findings from the surveys.

IMPLICATIONS FOR NURSING

Findings will help nurses across sectors of primary, secondary, and tertiary care create resilience-enhancing interventions and prevent mental health crises in this community.

IMPACT STATEMENT

This findings from this study will inform local mental health interventions on the Reservation. The study provides a reproducible design to adapt to other Indigenous communities.

PUBLIC CONTRIBUTION

A community advisory board was a partner in every stage of the study. Children and caregivers participated in data collection.

CONTRIBUTION TO THE WIDER CLINICAL COMMUNITY

This research provides knowledge that will further social justice efforts within nursing to promote health equity across diverse populations.

Comorbidity of anxiety/affective, conduct/antisocial, attention deficit, and alcohol use disorders with suicidal behaviors in an American Indian community sample of adults and adolescents

AIMS

To study the associations of anxiety/affective disorders, conduct/antisocial disorders (ASPD/CD), attention deficit disorders (ADHD), and alcohol use disorders (AUD) with suicidal behaviors in an American Indian (AI) community sample of adolescents and adults.

METHODS

Participants were AI (360 adolescents, 925 adults) recruited from reservations who were assessed with the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA).

RESULTS

Among AI adults (mean age = 33 years), 17% percent reported lifetime experiences of suicidal thoughts (ideation and/or plans) and 14% reported suicidal acts (including either a suicide attempt history or verified death by suicide; n = 19 deaths). Among AI adolescents (mean age = 15 years), 20% experienced suicidal thoughts and 9% experienced suicidal acts (including 3 deaths). In logistic regression analyses, suicidal thoughts were significantly associated with lifetime diagnoses of affective disorder, CD and ADHD in adolescents, and with anxiety disorder, affective disorder, and ASPD/CD in adults. Suicidal acts were associated with affective disorder, ADHD, and alcohol drinking in adolescents and with anxiety disorder, ASPD/CD and AUD in adults. The number of comorbid disorders greatly increased the risk of both suicidal thoughts and acts among both adolescents and adults.

CONCLUSIONS

In addition to affective disorders, both ADHD and CD in adolescents, and ASPD in adults, demonstrated an association with suicidal thoughts. Alcohol use by adolescents and AUD among adults also were associated with suicidal attempts in this AI sample. These findings suggest need for additional research and potential integration of alcohol in screening and intervention programs focused on the prevention of suicide among AI.

Genetic Factors Associated with Suicidal Behaviors and Alcohol Use Disorders in an American Indian Population

American Indians (AI) demonstrate the highest rates of both suicidal behaviors (SB) and alcohol use disorders (AUD) among all ethnic groups in the US. Rates of suicide and AUD vary substantially between tribal groups and across different geographical regions, underscoring a need to delineate more specific risk and resilience factors. Using data from over 740 AI living within eight contiguous reservations, we assessed genetic risk factors for SB by investigating: (1) possible genetic overlap with AUD, and (2) impacts of rare and low frequency genomic variants. Suicidal behaviors included lifetime history of suicidal thoughts and acts, including verified suicide deaths, scored using a ranking variable for the SB phenotype (range 0-4). We identified five loci significantly associated with SB and AUD, two of which are intergenic and three intronic on genes AACSP1, ANK1, and FBXO11. Nonsynonymous rare mutations in four genes including SERPINF1 (PEDF), ZNF30, CD34, and SLC5A9, and non-intronic rare mutations in genes OPRD1, HSD17B3 and one lincRNA were significantly associated with SB. One identified pathway related to hypoxia-inducible factor (HIF) regulation, whose 83 nonsynonymous rare variants on 10 genes were significantly linked to SB as well.

This study represents the first investigation of genetic factors for SB in an American Indian population that has high risk for suicide. Our study suggests that bivariate association analysis between comorbid disorders can increase statistical power; and rare variant analysis in a high-risk population enabled by whole-genome sequencing has the potential to identify novel genetic factors. Although such findings may be population specific, rare functional mutations relating to PEDF and HIF regulation align with past reports and suggest a biological mechanism for suicide risk and a potential therapeutic target for intervention.

Poor self-reported sleep quality associated with suicide risk in a community sample of American Indian adults

Study Objectives

Although American Indian/Alaska Native (AI/AN) have high suicide rates few studies have systematically investigated sleep quality and its association with suicidal behaviors in AI/AN. This study is a cross-sectional investigation of self-reported sleep quality and suicidal behaviors in an adult AI population.

Methods

A semi-structured interview was used to collect data on suicidal ideation, suicidal plans, and suicidal attempts and the Pittsburgh Sleep Quality Index (PSQI) was collected to assess sleep quality in American Indian adults.

Results

In this sample (n = 477), 91 (19%) of the participants endorsed suicidal ideation (thoughts and plans), and 66 (14%) reported suicidal attempts, including four who subsequently died by suicide. More women reported suicidal thoughts or acts than men. Those endorsing suicidal thoughts slept fewer hours during the night, reported more nocturnal awakenings, and showed poorer subjective sleep quality according to PSQI total scores compared to those with no suicidal thoughts or acts. Participants with suicidal acts (n = 66) reported more bad dreams and higher PSQI total scores compared to those with no suicidal thoughts or acts. When those with any suicidal thoughts or acts (n = 157, 33%) were compared to those without, they were more likely to endorse nocturnal awakenings and bad dreams and demonstrated significantly higher PSQI total scores.

Conclusions

Although additional research is needed to evaluate sleep disturbances as a proximal, causal risk factor for suicidal behaviors in AI, findings highlight need for further study of sleep as a warning sign and intervention tool for suicide prevention among American Indian adults.

Caring Texts, a strength-based, suicide prevention trial in 5 native communities: Research design and methods

BACKGROUND

Despite their intrinsic strengths and resilience, some American Indian and Alaska Native (AI/AN) communities experience among the highest rates of suicide of any racial and ethnic group. Caring Contacts is one of the only interventions shown to reduce suicide in clinical trials, but it has not been tested in AI/AN settings.

OBJECTIVE

To compare the effectiveness of Enhanced Usual Care (control) to Enhanced Usual Care augmented with a culturally adapted version of Caring Contacts (intervention) for reducing suicidal ideation, suicide attempts, and suicide-related hospitalizations.

METHODS

We are implementing a single blind randomized controlled trial of Caring Contacts in five AI/AN communities across the country (South Dakota, Montana, Oklahoma, and Alaska). Eligible participants have to be (1) actively suicidal or have made a suicide attempt within the past year; (2) at least 18 years of age; (3) AI/AN; (4) able to speak and read English; (5) able to participate voluntarily; (6) willing to be contacted by text, email or postal mail; and (7) able to provide consent. Following consent and baseline assessment, participants are randomized to receive either Enhanced Usual Care alone, or Enhanced Usual Care with 12 months (25 messages) of culturally adapted Caring Contacts. Follow-up assessments are conducted at 12 and 18 months.

CONCLUSIONS

If effective, this study of Caring Contacts will inform programs to reduce suicide in the study communities as well as inform future research on Caring Contacts in other tribal settings. Modifications to continue the trial during the COVID-19 pandemic are discussed.

Trauma, historical trauma, PTSD and suicide in an American Indian community sample

AIMS

To study the associations between perceived historical trauma, current traumatic events, diagnoses of post-traumatic stress disorder (PTSD), and suicidal behaviors in an American Indian community sample.

METHODS

Participants were American Indians recruited from reservations who were assessed with the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA), as well as the Historical Loss Scale, Historical Loss Associated Symptoms Scale, and Stressful Life Events Scale.

RESULTS

In data from 447 American Indian adults (mean age = 33 years), twenty percent reported lifetime experiences of suicidal thoughts (ideation and/or plans) and 14% reported suicidal acts, (including either a suicide attempt history or verified death by suicide (n = 4)). Diagnosis of PTSD and experience of assaultive trauma were each significantly associated with suicidal thoughts and acts, although assaultive trauma did not remain significant in models adjusting for gender and PTSD. High endorsement of symptoms associated with historical trauma was significantly associated with suicidal acts, and this remained significant when adjusting for gender and PTSD.

CONCLUSIONS

PTSD and historical trauma have an association with suicide and suicidal attempts in this American Indian community. Although further research is needed to evaluate the causal nature of these relations, these findings suggest treatment and prevention programs for American Indian suicide may benefit from addressing issues related to feelings of historical losses, PTSD, and their associated symptomatology.

Community Perspectives on Social Influences on Suicide Within a Native American Reservation

Relative to the general population, Native Americans (NA) bear a disproportionate burden of suicide-related mortality rates. NA males and females aged 15 to 24 years experience suicide rates nearly 3 times than the U.S. all races rates in this age group. Although efforts have been made to understand and reduce suicide in tribal communities, a large portion has focused on individual characteristics with less attention given to social factors that may also inform suicide. This article aims to build on a local conceptual model of NA youth suicide by examining additional potential social factors through qualitative interviews. Findings from the thematic analysis resulted in the identification of seven perceived social influences: contagion, violence and abuse, discrimination and bullying, negative expectations, spirituality, social support, and cultural strengths. Public health approaches to reduce suicide should consider local social factors that resonate with tribal communities to build resilience.

Racism and Poverty are Barriers to the Treatment of Youth Mental Health Concerns

OBJECTIVE

Traditional studies of treatment moderators have focused largely on psychological factors such as clinical severity. Racial and economic inequity exert large effects on youth mental health, on treatment efficacy, and on the likelihood of receiving treatment altogether. Yet, these factors are studied less often by clinical psychological scientists.

METHOD

We conducted a narrative review of literature on racial and economic inequities and their impact on youth mental health.

RESULTS

First, systemic problems such as racism and poverty increase the risk of developing complex health issues and decrease the likelihood of benefiting from treatment. Second, attitudinal barriers, such as mistrust associated with treatments provided by researchers and government agencies, decrease the likelihood that minoritized groups will engage with or benefit from evidence-based treatments. Third, minoritized and underserved communities are especially unlikely to receive evidence-based treatment.

CONCLUSION

Clinical psychological science has unique insights that can help address systemic inequities that can decrease treatment efficacy for youth mental health treatment. Psychological scientists can help eliminate disparities in accessing evidence-based treatment and help end violent policies in underserved minoritized communities by at the very least (1) building and supporting scalable community-based treatments as well as (2) publicly advocating for an end to violent policies that impose negative social costs.

Evaluating the Cross-Cultural Measurement Invariance of the PHQ-9 between American Indian/Alaska Native Adults and Diverse Racial and Ethnic Groups

BACKGROUND

The Patient Health Questionnaire-9 (PHQ-9), a self-reported depression screening instrument for measurement-based care (MBC), may have cross-cultural measurement invariance (MI) with a regional group of American Indian/Alaska Native (AI/AN) and non-Hispanic White adults. However, to ensure health equity, research was needed on the cross-cultural MI of the PHQ-9 between other groups of AI/AN peoples and diverse populations.

METHODS

We assessed the MI of the one-factor PHQ-9 model and five previously identified two-factor models between non-Hispanic AI/AN adults (ages 18-64) from healthcare systems A (n=1,759) and B (n=2,701) using secondary data and robust maximum likelihood estimation. We then tested either fully or partially invariant models for MI between either combined or separate AI/AN groups, respectively, and Hispanic (n=7,974), White (n=7,974), Asian (n=6,988), Black (n=6,213), and Native Hawaiian/Pacific Islander (n=1,370) adults from healthcare system B. All had mental health or substance use disorder diagnoses and were seen in behavioral health or primary care from 1/1/2009-9/30/2017.

RESULTS

The one-factor PHQ-9 model was partially invariant, with two-factor models partially, or in one case fully, invariant between AI/AN groups. The one-factor model and three two-factor models were partially invariant between all seven groups, while a two-factor model was fully invariant and another partially invariant between a combined AI/AN group and other racial and ethnic groups.

CONCLUSIONS

Achieving health equity in MBC requires ensuring the cross-cultural validity of measurement tools. Before comparing mean scores, PHQ-9 models should be assessed for individual racial and ethnic group fit for adults with mental health or substance use disorders.

Do assets explain the relation between race/ethnicity and probable depression in U.S. adults?

Depression is a leading cause of disability in the U.S. across all race/ethnicity groups. While non-Hispanic Black and Hispanic persons have worse physical health on most indicators than non-Hispanic White persons, the literature on the association between race/ethnicity and rates of depression is mixed. Given unequal distribution of assets across racial/ethnic groups, it is possible that social and economic differences may explain differential rates of depression across race/ethnicity groups. Using National Health and Nutrition Examination Survey (NHANES) data from 2007–2016, we constructed a nationally representative sample of 26,382 adults over 18 years old (11,072 non-Hispanic White, 5,610 non-Hispanic Black, 6,981 Hispanic, and 2,719 Other race). We measured symptoms of depression using the Patient Health Questionnaire-9 (PHQ-9), with a score of 10 or more indicating probable depression. We identified three kinds of assets: financial assets (income), physical assets (home ownership), and social assets (marital status and education). We estimated the weighted prevalence of probable depression across race/ethnicity groups, odds ratios controlling for assets, and predicted probabilities of probable depression across race/ethnicity and asset groups. Three results contribute to our understanding of the differences in probable depression rates between race/ethnicity groups: 1) Non-Hispanic Black and Hispanic persons had a higher weighted prevalence of probable depression in the U.S. than non-Hispanic White persons. In models unadjusted for assets, non-Hispanic Black and Hispanic persons had 1.3 greater odds of probable depression than non-Hispanic White persons (p<0.01). 2) We found an inverse relation between assets and probable depression across all race-ethnicity groups. Also, non-Hispanic Black and Hispanic persons had fewer assets than non-Hispanic Whites. 3) When we controlled for assets, non-Hispanic Black and Hispanic persons had 0.8 times lower odds of probable depression than non-Hispanic White persons (p<0.05). Thus, when holding assets constant, minorities had better mental health than non-Hispanic White persons in the U.S. These three findings help to reconcile findings in the literature on race/ethnicity and depression. Given vastly unequal distribution of wealth in the U.S., it is not surprising that racial minorities, who hold fewer assets, would have an overall larger prevalence of mental illness, as seen in unadjusted estimates. Once assets are taken into account, Black and Hispanic persons appear to have better mental health than non-Hispanic White persons. Assets may explain much of the relation between race/ethnicity group and depression in the U.S. Future research should consider the role of assets in protecting against mental illness.
