Latent Classes of Substance Use Among American Indian and White Students Living on or Near Reservations, 2009-2013

A comparison of alcohol and commercial tobacco use in populous American Indian/Alaska Native states

BACKGROUND

Modern research suggests that the racial influence on smoking and drinking behaviors may not be as prevalent as once thought. This study utilizes national survey data to compare binge drinking and commercial cigarette smoking behaviors between American Indians/Alaskan Natives (AI/AN) and non-Hispanic Whites in the five most populous AI/AN U.S. states.

METHODS

Data were analyzed from the Behavioral Risk Factor Surveillance System (BRFSS) from 2018 to 2022; White (n=79,405), AI/AN (n=11,007). Data analyses include frequency statistics, followed by two model evaluations comparing main effects of race/ethnicity and sex for both binge drinking and commercial cigarette smoking behaviors, and subgroup estimates of race/ethnicity by sex. An ANOVA was utilized to evaluate differences by race/ethnicity, sex, and race/ethnicity by sex subgroups by states.

RESULTS

Males were over twice as likely to engage in binge drinking, with no significant differences found between people identifying as AI/AN and White individuals. Both White and AI/AN males were twice as likely to engage in binge drinking, compared to their White female counterparts. AI/AN individuals were over twice as likely to engage in commercial cigarette smoking compared to their White counterparts.

CONCLUSIONS

Results showed no significance differences in AI/AN versus White individuals in binge drinking (controlling for sex, age, and income), while there were significant differences by sex (controlling for race/ethnicity, age, and income). People identifying as AI/AN were significantly more likely to engage in commercial cigarette smoking compared to White individuals, signifying the importance of racial/ethnical and covariate considerations when establishing public health interventions.

Primary Socialization Theory and American Indian Adolescents' Intentions to Use Substances

Intentions to use substances are a robust risk factor for future substance use. Primary Socialization Theory (PST), with its focus on relational factors, is well-suited to provide insight into American Indian adolescents' intentions to use substances given the importance of relationships in American Indian communities. The goal of the present study was to examine the role of PST-related factors (i.e., parental monitoring, peer pressure, attitudes toward school) on likelihood of intending to use substances (i.e., alcohol, cigarettes, cannabis, other drugs) among American Indian adolescents.

American Indian participants (N = 8,950, 50.7% females) were recruited as a part of the Our Youth, Our Future survey, an ongoing surveillance of substance use among 7th-12th graders attending school on or near reservations.

Parental monitoring was found to be associated with decreased likelihood of intending to use alcohol (aOR = 0.97, 95%CI [0.96, 0.99]), cigarettes (aOR = 0.96, 95%CI [0.94, 0.98]), cannabis (aOR = 0.95, 95%CI [0.94, 0.96]), and other drugs (aOR = 0.94, 95%CI [0.92, 0.96]). Peer pressure was associated with increased likelihood of intending to use alcohol (aOR = 1.68, 95%CI [1.59, 1.78]), cigarettes (aOR = 1.73, 95%CI [1.60, 1.86]), cannabis (aOR = 1.81, 95%CI [1.71, 1.92]), and other drugs (aOR = 1.40, 95%CI [1.26, 1.56]). More positive attitudes toward school were associated with decreased likelihood of intending to use alcohol (aOR = 0.93, 95%CI [0.91, 0.94]), cigarettes (aOR = 0.92, 95%CI [0.90, 0.94]), cannabis (aOR = 0.90, 95%CI [0.88, 0.91]), and other drugs (aOR = 0.96, 95%CI [0.93, 0.99]).

Results support incorporating social relationships into interventions aiming to prevent substance use initiation, including promoting positive parental monitoring, peer interactions, and school attitudes.

Perceived racial discrimination and polysubstance use among racial/ethnic minority adolescents in the United States

OBJECTIVE

Polysubstance use among adolescents is a significant public health concern, yet most studies on adolescent substance use focus on a singular substance. This study is one of the first to investigate the association between perceived racial discrimination (PRD) in school and polysubstance use among racial/ethnic minority adolescents using a nationally representative sample.

METHODS

Data was from the 2021 Adolescent Behaviors and Experiences Survey. The sample included 4145 racial/ethnic minority adolescents (52.8% female). Hierarchical binary logistic regression was used to examine the association between PRD in school and polysubstance use among racial/ethnic minority adolescents.

RESULTS

About 12% of racial/ethnic minority adolescents engaged in polysubstance use and 23.4% reported experiencing PRD in school sometimes/most of the time/always. Controlling for other factors, experiencing PRD in school sometimes/most of the time/always was associated with 1.52 times higher odds of polysubstance use when compared to adolescents who never experienced PRD in school (OR=1.52, p=.044, 95% CI=1.01-2.30). Cyberbullying victimization, symptoms of depression, and being emotionally abused by a parent during COVID-19 were also associated with polysubstance use.

CONCLUSION

Controlling for demographic characteristics and psychosocial stressors, PRD in school was significantly associated with higher odds of polysubstance use among racial/ethnic minority adolescents. The findings of this study could inform clinicians and policymakers of the association between PRD in school and polysubstance use, which could contribute to early identification of polysubstance use among racial/ethnic minority adolescents.

Intersecting sex and American Indian identity moderates school and individual correlates of binge drinking among reservation-area adolescents

Reservation-area American Indian (AI) youth demonstrate higher rates of binge drinking (BD) than their non-AI peers. However, individual and school-level differences in BD disparities between reservation-area AI/non-AI female and male adolescents remain unexamined. This study applies an Intersectional framework to examine risk and protective factors of BD among reservation-area youth at the intersection of their sex and AI identities. A nationally representative sample of adolescents (N = 14,769; Mage = 14.6, 49% female; 61% AI) attending 103 reservation-serving schools completed a survey between 2015 and 2019. Multilevel modeling was used to examine differences in risk and protective factors of BD between AI and non-AI male and female adolescents. Our findings indicate that the effects of student and school-level risk and protective factors on adolescents' BD are driven primarily by sex within AI and non-AI groups. Implications for future confirmatory research and tailoring school-based prevention programs are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

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.

Gender-based differences in abstention and desistance from drug use among American Indian adolescents

Informed by the social control theoretical perspective, this study intends to identify the factors more likely to differentiate American Indian (AI) adolescents who never used illicit drugs (abstainers) and those who used drugs in the past but did not report recent drug usage (desisters) from their peers who reported lifetime and recent drug usage (persisters). This secondary analysis is based on data from a multi-site study conducted between 2009 and 2013. It is based on a gender-balanced sample (N = 3,380) of AI adolescents (50.50% male; Mean age = 14.75; SD = 1.69) representing the major AI languages and cultural groups in the U.S. Half of the AI adolescents reported lifetime drug use (50.40%), 37.50% never used drugs, and 12.10% stopped using drugs. When controlling for the variables included in the analysis, AI boys were significantly more likely than AI girls to desist from drug use. Both boys and girls who never used drugs tended to be younger, were less likely to have delinquent friends and a lower level of self-control, had stronger bonds to school, but lower levels of family attachment, and reported increased parental supervision. Compared to drug users, desisters associated significantly less with delinquent peers. While school attachment, self-control, and parental monitoring did not differentiate female desisters from female drug users, adolescent boys who desisted from drug use were more likely to report higher levels of school attachment and parental monitoring and their level of self-control was less likely to be low.

Cultural Protection from Polysubstance Use Among Native American Adolescents and Young Adults

Reservation-based Native American youth are at disproportionate risk for high-risk substance use. The culture-as-treatment hypothesis suggests aspects of tribal culture can support prevention and healing in this context; however, the protective role of communal mastery and tribal identity have yet to be fully explored. The objectives of this study were to investigate (1) the relationship between cultural factors and high-risk substance use, which includes polysubstance use, early initiation of alcohol and illicit drugs, and binge drinking, and (2) substance use frequency and prevalence of various substances via cross-sectional design. Multiple logistic regression modeling was used to analyze data from 288 tribal members (15–24 years of age) residing on/near the Fort Peck Reservation in the Northern Plains. When controlling for childhood trauma and school attendance, having at least a high school education (OR = 0.434, p = 0.028), increased communal mastery (OR = 0.931, p = 0.007), and higher levels of tribal identity (OR = 0.579, p = 0.009) were significantly associated with lower odds of polysubstance use. Overall prevalence of polysubstance use was 50%, and binge drinking had the highest single substance prevalence (66%). Prevalence of early initiation of substances (≤ 14 years) was inhalants (70%), alcohol (61%), marijuana (74%), methamphetamine (23%), and prescription drug misuse (23%). Hydrocodone, an opioid, was the most frequently misused prescription drug. Findings indicate programs focused on promoting education engagement, communal mastery, and tribal identity may mitigate substance use for Native American adolescents living in high-risk, reservation-based settings.

Extreme Binge Drinking During Adolescence: Associations With Subsequent Substance Use Disorders in American Indian and Mexican American Young Adults

OBJECTIVE

This study collected retrospective data on adolescent binge drinking (ABD) (5 drinks for boys, 4 for girls per occasion at least once per month) and/or extreme adolescent binge drinking (EABD) (10 or more drinks per occasion at least once per month) and tested for associations with demographic and diagnostics variables including alcohol and other substance use disorders (AUD/SUD).

METHODS

Cross-sectional data were collected from young adult (age 18-30 yrs) American Indians (AI) (n = 534) and Mexican Americans (MA) (n = 704) using a semi-structured diagnostic instrument.

RESULTS

Thirty percent (30%) of the sample reported ABD and 21% reported EABD. Those having had monthly ABD were more likely to be AI and have less education; those having had EABD were more likely to be AI, male, younger, have less education and lower economic status compared to participants without ABD. ABD/EABD was associated with higher impulsivity, a family history of AUD, and lower level of response to alcohol (ORs = 1.0-2.0), as well as with adult AUD (ORs = 3.7-48), other substance use disorders (ORs = 3.5-9), and conduct disorder/ antisocial personality disorder (ORs = 2.0-2.6), but not with anxiety/depression. Monthly EABD further increased the odds of AUD/SUD.

CONCLUSIONS

Although binge drinking was more common in AI compared to MA, there were little effects of race in individual risk factor analyses. Monthly ABD and EABD were common among these AI/MA as adolescents, and, as with other ethnic groups, these drinking patterns resulted in highly significant increases in the odds of developing alcohol and other substance use disorders in young adulthood.

Latent Class Analysis and Predictors of Marijuana Use among Reservation-based American Indian High School Students

American Indian (AI) youth residing on reservations report higher rates of marijuana use compared to national youth. Latent class analysis (LCA) was used to identify unique types of marijuana use among 2,884 AI high school students surveyed from 26 schools across six indigenous geographic regions. Predictors of class membership were then assessed using social, cultural, and individual measures relevant to adolescent substance use. Classes and predictors were examined separately for males and females. Four-class models fit the data best for both male and female AI students. Classes differed by sex, as did predictors. Overall, social predictors related to family and peers and the individual predictor, using marijuana to cope, were the best predictors of class membership. Based on these results, prevention and intervention efforts should provide alternative coping methods for these adolescents who often live in difficult situations, and should focus on encouraging parents to effectively monitor their adolescent children and communicate clear sanctions against marijuana use.

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.

Patterns of substance use among adolescents: A systematic review

PURPOSE

This review characterizes empirically derived patterns of multiple (multi-) substance use among adolescents. A secondary objective was to examine the extent to which mental health symptomatology was included in the empirical analyses examining substance use patterns.

METHODS

Eligible studies included those that used cluster-based approaches, included the assessment of at least two different substances, and were based on study samples with mean ages between 11 and 18 years. 4665 records were screened including 461 studies for full-text screening.

RESULTS

70 studies were included with common clusters being: low use, single or dual substance use, moderate general multi-use, and high multi-use. The most common patterns of single or multi-substance use were: alcohol only, alcohol with cannabis and/or tobacco, and use of alcohol, tobacco, and cannabis with and without other drugs. Lower socioeconomic status, older age, and male gender were consistent predictors of multi-use clusters. Only 37 % of studies compared differences in levels of mental health across clusters with symptoms consistently associated with a greater likelihood of multi-use. Only 29 % of studies included mental health indicators in cluster-based analyses, with over half identifying distinct mental health and substance use clusters. Fit indices in cluster analyses and measurement properties of substance use were heterogeneous and inconsistently reported across studies.

CONCLUSIONS

Distinct patterns of substance use were derived but methodological differences prevented direct comparison and reduced capacity to generalize across studies. There is a need to establish standardized methodological approaches to identify robust patterns of substance use to enhance etiological, prognostic, and intervention research.

Delta Event-Related Oscillations Are Related to a History of Extreme Binge Drinking in Adolescence and Lifetime Suicide Risk

Alcohol exposure typically begins in adolescence, and heavy binge drinking is associated with health risk behaviors. Event-related oscillations (EROs) may represent sensitive biomarkers or endophenotypes for early alcohol exposure as well as other risk behaviors such as suicidal thoughts and actions. In this study, young adults (age 18–30 years) of American Indian (AI) (n = 479) and Mexican American (MA) (n = 705) ancestry were clinically assessed, and EROs were generated to happy, sad and neutral faces. Extreme adolescent binge drinking (10+ drinks) was common (20%) in this population of AI/MA and associated with a significantly increased risk of a lifetime history of suicidal acts (SA, suicide attempts, deaths) but not suicidal thoughts (ST, ideation, plans). ST were reported among MA participants, whereas SA were more common among AI young adults. Extreme adolescent binge drinking was also associated with errors in detection of sad and neutral faces, increases in delta ERO energy, and decreases in phase locking (PL), particularly in parietal areas. A lifetime history of ST was associated with increases in delta ERO energy and PL, whereas SA were associated with decreases in both. These studies suggest that ERO measures may represent important potential biomarkers of adolescent extreme binge drinking and risk for suicidal behaviors.

Distinct psychological profiles among college students with substance use: A cluster analytic approach

Substance use in youth is a central public health concern, related to deleterious consequences at psychological, social, and cognitive/cerebral levels. Previous research has identified impulsivity and consumption motives as key factors in the emergence of excessive substance use among college students. However, most studies have focused on a specific substance and have considered this population as a unitary group, ignoring the potential heterogeneity in psychological profiles. We used a cluster analytic approach to explore the heterogeneity in a large sample (N = 2741) of substance users (i.e., tobacco, alcohol, cannabis, ecstasy, cocaine, heroin) on impulsivity and consumption motives. We identified four clusters: The first two clusters, associated with good self-esteem, low anxiety, and moderate substance use, were respectively characterized by low impulsivity and consumption motives (Cluster 1) and by high social and enhancement motives without marked impulsivity (Cluster 2). The two other clusters were conversely related to low self-esteem and high anxiety, and characterized by high consumption motives (particularly conformity) together with elevated urgency (Cluster 3) and by globally increased impulsivity and consumption motives (Cluster 4). These two clusters were also associated with higher substance use. These results highlight the existence of distinct psychological profiles of substance users and underline the need to develop targeted prevention and intervention programs (e.g., focusing on the specific impulsivity facets and consumption motives presented by each subgroup). Based on these findings, we also suggest extending the exploration of distinct profiles of substance users by targeting other psychological variables (e.g., self-esteem).

Early onset of cannabis use and alcohol intoxication predicts prescription drug misuse in American Indian and non-American Indian adolescents living on or near reservations

BACKGROUND

Prescription drug misuse (PDM) is a growing issue within the American Indian (AI) population, especially in younger populations.

OBJECTIVES

This study estimates relationships between PDM and early initiation (prior to 14 yrs) of cannabis use and alcohol intoxication for a national sample of AI and non-AI adolescents attending schools on or near reservations.

METHOD

Participants were 2580 students (50.2% female; 58.1% AI), ages 15-18, attending schools located on or near an AI reservation. Four models of PDM were estimated: 1) demographic variables; 2) demographics plus cannabis use initiation status; 3) demographics plus alcohol intoxication initiation status; and 4) all variables. All analyses were conducted using multilevel modeling.

RESULTS

Results indicated that early onset of cannabis use and alcohol intoxication were individually significant predictors of PDM for AI and non-AI adolescents, with odds ratios (OR) of 47.00 for cannabis (p <.01) and 35.73 (p <.01) for intoxication and with no significant differences by race (AI vs. non-AI). Results also indicated a greater likelihood of PDM when a student was an early initiator of both cannabis use and intoxication than when they were one or the other. Finally, there was a significantly greater association between cannabis use and PDM (ORearlycannabis = 24.95, p <.01) than between intoxication and PDM (ORearlyintoxication = 3.98, p <.01) when both predictors were in the model.

CONCLUSIONS

These findings suggest that for AI and non-AI youth who have some shared living experience, early initiation of cannabis use and alcohol intoxication are risk factors that are similarly related to PDM and that targeting early initiation for both groups of adolescents is critical in prevention of PDM.

Risk and Protective Factors of Current Opioid Use Among Youth Living on or Near American Indian Reservations: An Application of Machine Learning

Opioid use among youth, particularly among American Indian (AI) youth, is rising, resulting in a large number of accidental overdoses and deaths. In order to develop effective prevention strategies, we need to use exploratory data analysis to identify previously unknown predictors of opioid use among youth living on or near reservations. The present study is an application of Machine Learning, a type of exploratory data analysis, to the Our Youth, Our Future epidemiological survey (N = 6482) to determine salient risk and protective factors for past 30-day opioid use. The Machine Learning algorithm identified 11 salient risk and protective factors. Importantly, highest risk was conferred for those reporting recent cocaine use, having ever tried a narcotic other than heroin, and identifying as American Indian. Protective factors included never having tried opioids other than heroin, infrequent binge drinking, having fewer friends pressuring you to use illicit drugs, initiating alcohol use at a later age, and being older. This model explained 61% of the variance in the training sample and, on average, 24% of the variance in the bootstrapped samples. Taken together, this model identifies known predictors of 30-day opioid use, for example, recent substance use, as well as unknown predictors including being AI, Snapchat use, and peer encouragement for use. Notably, recent cocaine use was a more salient predictor of recent opioid use than lifetime opioid use.

Spirituality, Ethnic Identity, and Substance Use among American Indian/Alaska Native Adolescents in California

Background. American Indian/Alaska Native (AIAN) adolescents have a higher prevalence of commercial tobacco, alcohol, and marijuana use than other racial/ethnic groups in the United States. It is unclear whether cultural factors such as ethnic identity, spirituality, and ceremonial use of traditional tobacco are associated with substance use, especially use of emerging tobacco products such as electronic cigarettes, among AIAN adolescents. Methods. This study investigated the association between hypothesized cultural protective factors (ethnic identity, spirituality, and ceremonial use of traditional tobacco) and past-month use of commercial cigarettes, e-cigarettes, marijuana, blunts, and alcohol among 156 AIAN adolescents in California (mean age = 15.3 years, 55% female). Adolescents from six AIAN schools and afterschool programs completed paper-and-pencil surveys. We used Logistic regression analyses to identify the significant cultural correlates of past-month substance use, controlling for demographic covariates. Results. As hypothesized, strong ethnic identity was protective against cigarette, marijuana, and alcohol use. However, it was not protective against e-cigarette or blunt use. Spirituality was associated with an increased risk of cigarette and marijuana use. Previous ceremonial use of traditional tobacco was not associated with past-month recreational substance use. Conclusions. Results indicate that the associations between cultural factors and substance use vary across substances. Future research should identify cultural factors that protect AIAN adolescents against use of newer products such as e-cigarettes and blunts.

Predictors of Substance Use Latent Classes Among American Indian Youth Attending Schools On or Near Reservations

BACKGROUND AND OBJECTIVES

Identical latent classes of substance use for 7 to 8 grade and 9 to 12 grade American Indian (AI) youth living on or near reservations suggest that patterns of substance use are established early among these youth. This study examines relationships of substance-related factors to latent class membership and whether these relationships differ by grade group.

METHODS

In-school surveys were administered to 1503 7 to 8 grade and 1995 9 to 12 grade students from 46 schools on or near reservations during the 2009/2010 to 2012/2013 school years. Four-class latent class models of substance use were specified and five classes of substance-related factors (peers, substance availability, perceived harm, family, early initiation), plus grade level and gender, were evaluated as predictors.

RESULTS

For 7 to 8 grade students, substance-related factors differentiated nonusers from users, while for 9 to 12 graders, these factors also differentiated types of users. Early initiation and peer factors were strongly related to class membership, while other factors were less strongly related.

DISCUSSION AND CONCLUSIONS

Early initiation of alcohol or marijuana is strongly related to being in a substance-using class for AI youth. Because these youth tend to initiate use earlier that other US youth, prevention resources should be targeted to reaching them and their families before age 12.

SCIENTIFIC SIGNIFICANCE

Predictors of latent classes of substance use were identified for reservation-based AI youth. While the classes were identical for 7 to 8 grade and 9 to 12 grade youth, predictors varied across grade group, which may inform how best to develop prevention efforts unique to middle and high school AI youth.

Classes of drinking motives among American Indian youth drinkers

Research exploring American Indian (AI) youth drinking motives and their relation to negative outcomes is critical due to higher rates of alcohol use and early exposure to intoxication in the population. The purpose of this study is to explore classes of drinking motives as they relate to heavy episodic drinking, perceived discrimination, religious importance, ethnic identity, and ethnic pride. This study is part of an ongoing epidemiologic and etiologic investigation of substance use among AI youth drinkers living on or near reservations (n = 1,934, Mage = 15.31). A latent class analysis (LCA) was conducted to discern latent classes of drinking motives. Once latent classes were identified, differences in perceived discrimination, ethnic pride, ethnic identity, religious importance, and heavy episodic drinking were tested. A 2-class solution provided the best overall model fit to the data. The higher coping and enhancement motive class was associated with significantly greater heavy episodic drinking, perceived discrimination, and ethnic identity compared with the low motive class. Further, the class structure did not differ between 7th and 8th graders and 9th-12th graders. Results indicate that among AI youth, the class with strong motives to drink for coping or enhancement had higher ethnic identity, greater risk of heavy episodic drinking, and greater perceived discrimination compared with the class with low motives. Future research should examine additional factors and stressors that may be associated with these classes of drinking motives and are unique to the AI population.
