Onset, Comorbidity, and Predictors of Nicotine, Alcohol, and Marijuana Use Disorders Among North American Indigenous Adolescents

Frequency is not enough: Characterizing heterogenous patterns of cannabis use intensity among reservation-area American Indian youth

BACKGROUND

Reservation-area American Indian (AI) youth use cannabis at significantly higher rates than their national counterparts. This discrepancy is concerning, as cannabis use-particularly heavy use-can negatively impact adolescents' health. Studies primarily use frequency to classify cannabis use intensity; however, frequency alone may not fully capture heterogenous patterns of use. This study aimed to classify AI adolescents' cannabis use based on multiple intensity indicators, and to investigate interclass differences in problematic characteristics and outcomes of use.

METHODS

Participants were 799 reservation-area AI youth (7-12th grade) reporting 12-month cannabis use. Latent Class Analysis (LCA) was used to distinguish cannabis use intensity patterns based on frequency, typical intoxication levels and duration. Auxiliary tests using R3STEP and BCH 3-step procedures were used to assess class predictors (age, initiation age, sex) and interclass differences in simultaneous drug use, stress-motivated use, problems quitting and cannabis-related consequences.

RESULTS

Four classes emerged: Light Use (LU; 19 %), Occasional Intoxication (OI; 32 %), Mid-frequency Use(MU; 28 %), and Heavy Use (HU; 21 %). Age and initiation age correlated with membership odds in a heavier use class. Interclass differences in problematic characteristics and outcomes occurred between all classes, particularly for stress-motivated use and cannabis-related consequences-with HU reporting the most problematic characteristics and negative outcomes.

CONCLUSION

These findings suggest that accounting for multiple dimensions of usage intensity may be important in studies examining cannabis use and related problems among AI adolescents. Tailoring intervention programming to address complex cannabis use patterns, with particular focus on stress-coping skills and harm reduction, can ensure AI youth most at risk for cannabis problems gain maximal benefit from prevention efforts.

Does the time to nicotine dependence vary by internalizing symptoms for young people who use e-cigarettes? An analysis of the Population Assessment of Tobacco and Health (PATH) study, (Waves 1-5; 2013-2019)

OBJECTIVE

To determine the relationship between past-year internalizing symptoms and the time to first report of signs of nicotine dependence among young people.

METHODS

Secondary analysis using data from the Population Assessment of Tobacco and Health (PATH) (Waves 1-5; 2013-2019). The study included 2,102 (N = 5,031,691) young people (age 12-23 years) who reported past-30-day (P30D) e-cigarette use in one or more waves. Kaplan Meier curves, stratified by past year internalizing symptoms were used to estimate the time to the first report of three nicotine dependence symptoms (i.e., use within 30 min of waking, cravings, and really needing to use) following the first P30D e-cigarette use. Cox proportional hazard models were used to estimate crude and adjusted hazard ratios (AHR), comparing any past year internalizing symptoms to no past year internalizing symptoms.

RESULTS

We found no significant differences between past year internalizing symptoms and the time to the first report of cravings (AHR = 1.30, 95 % CI = 92-1.85), really needing to use (AHR = 1.31; 95 % CI = 0.92-1.89) and use within 30 min of waking for follow-up times 0-156 weeks (AHR = 0.84; 95 % CI = 0.55-1.30) and > 156 weeks (AHR = 0.41; 95 % CI = 0.04-4.67) respectively.

CONCLUSION

Past year internalizing symptoms did not modify the time to the first report of nicotine dependence among youth with P30D e-cigarette use. Further research is needed to understand how changing internalizing symptoms and e-cigarette use frequency influence nicotine dependence over time and, how this relationship impacts cessation behavior.

Systemic biases promoting the under-inclusion of marginalized groups in randomized controlled trials for co-occurring alcohol use and posttraumatic stress disorder: an intersectional analysis

Co-occurring posttraumatic stress disorder and alcohol use disorder is a major public health concern affecting millions of people. Although this disorder affects people from all groups, research shows that, when compared to White people, people of color systematically suffer worse chronicity and burden of disorder. Additionally, research shows that people of color endure a variety of barriers to accessing treatment and often require specialized or culturally appropriate care. Consequently, the array of treatments available must have been determined to be effective for people of color when they access treatment, and people of color must be well represented in research to ensure effective treatment. Therefore, randomized controlled trials testing treatments for this disorder must include racially diverse samples and ensure treatments are effective for all groups. Further, if they lack diversity, it is necessary to explore whether and how the process of conducting randomized controlled trials is biased toward the constrained inclusion of people of color. This study used a Matrix of Domination framework as an intersectional method to investigate this question. It assessed the inclusion of people by race and sex in randomized controlled trials for co-occurring posttraumatic stress disorder and alcohol use disorder. We found that people of color and White women are significantly underincluded in randomized controlled trials and that these studies are hegemonically, disciplinarily, and structurally biased in ways that facilitate the overrepresentation of White men and the underrepresentation of marginalized groups.

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.

Recruitment and retention of American Indian youth and caregivers in a culturally adapted prevention program

This article seeks to understand to what extent cultural engagement and substance use risk factors influence families' decisions to participate, and ultimately complete, a culturally grounded substance use prevention program. Using data from a 14-week culturally oriented family-based substance use prevention program, we examine predictors of successful recruitment and retention of American Indian youth and their caregivers. Guided by the theoretical model for developing culturally specific preventions, the community-based approach to recruitment resulted in 85.6% of eligible families from two American Indian communities agreeing to participate in the randomized controlled trial. After completion of baseline surveys, 57.3% of the intervention selected families initiated participation in the program sessions and 67.8% of these families completed participation in the program. We used logistic regression to analyze two different models: one that predicted whether invited families chose to participate and whether participating families attended eight or more sessions. Important predictors of participation in the intervention program included single-caregiver households, youth Indigenous language and cultural identity, youth early substance use initiation, and household substance use exposure. Overall, results from this study highlight the importance of fully engaged community research partnerships for multi-session family-based interventions, while identifying potential challenges to program recruitment and participation.

The protective role of valuing cultural activities on cannabis use in reserve-Dwelling First Nation youth

Cannabis legalization and use across North America disproportionately negatively affects North American Indigenous (NAI) youth. Cultural activities may function as an alternative reinforcer to protect against substance use and promote engagement in substance-free activities. The present study explored the role of valuing cultural activities on positive cannabis expectancies and past-month cannabis use. This was a secondary data analysis of data from one NAI adolescent population reporting any past-month cannabis use. 106 NAI adolescents (50% female) from a Canadian reserve community completed surveys in spring 2017. The Institutional Review Board, tribal chief, and council approved this study and informed consent, assent, and parental permission were obtained from participants. Linear regression results revealed significant main effects of positive cannabis expectancies (b = 2.926, SE = 1.198, p = .017, 95%CI[0.542, 5.309]) and valuing cultural activities (b= -0.471,SE = 0.234, p=.048, 95%CI[-0.937, -0.005]) on cannabis use, but no significant interaction between cannabis expectancies and valuing cultural activities. Previous research found valuing cultural activities significantly moderates the relationship between positive alcohol expectancies and alcohol use. Divergent findings may relate to the different historical significance of alcohol versus cannabis. Alcohol was used as a method to colonize NAIs. Thus, our non-significant interaction may result from cannabis not holding the same historical significance in comparison to alcohol for First Nation people, although this is only a hypothesis and should be confirmed with a follow up study. Despite this, calls from Indigenous communities emphasize the need for strength-based approaches and our results indicate that valuing culture is still significantly related to reduced cannabis use, independent of cannabis expectancies.

Tribal Reservation Adolescent Connections Study: A study protocol using mixed methods for examining social networks and associated outcomes among American Indian youth on a Northern Plains reservation

BACKGROUND

Rich cultural and traditional practices make interpersonal relationships vital for American Indian (AI) youth. Social relations and multigenerational networks (i.e., peer, family, kinship, and community) remain a salient fixture of AI culture, survival and thriving in reservation communities. Research in other populations has demonstrated how social networks impact youth risk and resilience, but data are lacking on AI adolescent networks. Intergenerational trauma from settler colonialism leads some AI youth to early initiation of substance use and subsequent substance misuse, along with disproportionately high risk for suicide and vulnerability to witnessing and experiencing violence. Using network data to develop prevention strategies among this population is a promising new avenue of research. In this study protocol paper, we describe the rationale and methodology of an exploratory study to be conducted with American Indian 9th and 10th graders at three schools on a Northern Plains reservation.

METHODS

This mixed methods study will collect quantitative social network surveys (N = 300) and qualitative interviews (n = 30). The study will examine the extent to which existing social network theories and data metrics adequately characterize AI youth networks or how they may need to be expanded for this population. Associations of network characteristics with risk and protective factors for substance use, exposure to violence, and suicide will also be examined.

DISCUSSION

This innovative methodological approach holds promise for informing the development of effective preventive approaches to address co-occurring risks for substance use, violence and suicide among AI adolescents. Understanding processes that impact social networks among AI adolescents can promote culturally resonant social relationships that may support better outcomes for youth.

Evidence-Based Assessment of Substance Use Disorder

The current review describes updated information on the evidence-based assessment of substance use disorder. We offer an overview of the state of the science for substance-related assessment targets, instruments (screening, diagnosis, outcome and treatment monitoring, and psychosocial functioning and wellbeing) and processes (relational and technical) as well as recommendations for each of these three components. We encourage assessors to reflect on their own biases, beliefs, and values, including how those relate to people that use substances, and to view the individual as a whole person. It is important to consider a person's profile of symptoms and functioning inclusive of strengths, comorbidities, and social and cultural determinants. Collaborating with the patient to select the assessment target that best fits their goals and integration of assessment information in a holistic manner is critical. We conclude by providing recommendations for assessment targets, instruments, and processes as well as recommendations for comprehensive substance use disorder assessment, and describe future directions for research.

Intergenerational residential school attendance and increased substance use among First Nation adults living off-reserve: An analysis of the aboriginal peoples survey 2017

Introduction

The Truth and Reconciliation Commission of Canada (TRCC) published 94 Calls to Action in 2015 to address long-term, intergenerational effects of the residential school system, highlighting the pervasive impact of colonialism on the wellbeing of Indigenous peoples in Canada. Indeed, research with Indigenous populations in Canada has captured that prior experiences of residential schools contributes to the intergenerational transmission of mental and physical health disparities. Despite these studies, further research is needed that contextualizes the influence of residential schools within broader frameworks that consider Indigenous social determinants of health in Canada. As such, the purpose of the present study was to examine patterns of substance use and mental and physical health among individuals with a history of residential school attendance (RSA) and individuals reporting parent or two-generation (parent and grandparent) RSA.

Method

Data from the Aboriginal Peoples Survey (2017), involving 10,030 First Nations individuals living off reserve, were analyzed.

Results

Self-reported mental and physical health scores were significantly lower among those had attended residential schools, whose parents attended residential schools, and whose grandparents attended residential schools, when compared to those who did not. Further, family RSA was associated with increased substance use among participants, though the findings were variable based on sex and specific substance analyzed. Meanwhile, individual and family RSA was not associated with increased likelihood of a mental health diagnosis.

Discussion

These findings provide additional support for how both parental and two-generation family histories of RSA are associated with individual physical and mental health outcomes. Further, these findings articulate the need for the TRCC's Calls to Action to be actually implemented, including community-based approaches that harness the strength of Indigenous people and communities who aim to close the gap in these health disparities for their children and families.

The association between early onset of alcohol, smokeless tobacco and marijuana use with adult binge drinking in United States

Binge drinking is a deadly pattern of excessive alcohol use that is associated with multiple diseases in the United States. To date, little is known about the associations between the early onset of substance use and other factors with the severity of adult binge drinking. The 2018 National Survey on Drug Use and Health data was used to identify binge drinking (binary and in number of days in the past month). Age at onset was categorized into four groups as 1-12, 13-14, 15-17, or beyond 18. Weighted multivariate logistic regression and Poisson regression analyses were performed to examine the associations between early onset of alcohol, smokeless tobacco, and marijuana use with binge drinking. The severity of binge drinking was statistically significantly associated with substance use (4.15 days in a month), early onset of alcohol, smokeless tobacco, and marijuana use (2.15-4.93 days, all p-values < 0.0001), after accounting for the covariates. Past year substance use disorder is strongly associated with binge drinking. The severity of adult binge drinking is significantly associated with early onset of substance use including alcohol, smokeless tobacco, and marijuana. Continued efforts are warranted to improve substance use prevention and treatment tailored for adolescents and youths to prevent development of adult binge drinking.

Application of the acquired preparedness model for alcohol and cigarette use among reserve-dwelling first nation adolescents

OBJECTIVE

North American Indigenous youth experience disproportionate harm associated with alcohol and cigarette use compared to other racial/ethnic groups. The Acquired Preparedness Model (APM), developed and tested in primarily White samples, hypothesizes that urgency contributes to risk for substance use by influencing the degree to which adolescents attend to positive aspects of substance use, leading to the development of more positive expectations about the consequences of substance use, and increasing subsequent substance use. The purpose of the present study was to provide an initial test of whether the APM generalizes to understanding alcohol and cigarette use among high-risk First Nation adolescents.

METHOD

First Nation adolescents (n = 106, Mage = 14.6, 50.0% female) recruited from reserve communities in Eastern Canada completed self-report measures as part of a larger community-based participatory research project. Procedures were approved by tribal chief, council, and university IRB.

RESULTS

The hypothesized model demonstrated excellent fit for alcohol use, χ²(1) = 1.07, p = .30, CFI = 0.99, RMSEA = .03, SRMR = .02, and adequate fit for cigarette use, χ²(1) = 2.58, p = .11, CFI = 0.98, RMSEA = 0.12, SRMR = 0.03. The indirect effects of urgency on alcohol consumption and cigarette smoking through alcohol and cigarette expectancies were each significant.

CONCLUSIONS

Findings of the present study provide initial support for the generalizability of the APM in understanding risk for alcohol and cigarette use among reserve-dwelling First Nation youth. The next important step is to replicate this finding in a prospective sample. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Racial and Ethnic Differences in Cannabis Use and Cannabis Use Disorder: Implications for Researchers

PURPOSE

Heavy and prolonged use of cannabis is associated with several adverse health, legal and social consequences. Although cannabis use impacts all U.S. racial/ethnic groups, studies have revealed racial/ethnic disparities in the initiation, prevalence, prevention and treatment of cannabis use and Cannabis Use Disorder (CUD). This review provides an overview of recent studies on cannabis and CUD by race/ethnicity and a discussion of implications for cannabis researchers.

FINDINGS

The majority of studies focused on cannabis use and CUD among African American/Black individuals, with the smallest number of studies found among Native Hawaiians/Pacific Islanders. The limited number of studies highlight unique risk and protective factors for each racial/ethnic group, such as gender, mental health status, polysubstance use and cultural identity.

SUMMARY

Future cannabis studies should aim to provide a deeper foundational understanding of factors that promote the initiation, maintenance, prevention and treatment of cannabis use and CUD among racial/ethnic groups. Cannabis studies should be unique to each racial/ethnic group and move beyond racial comparisons.

Factors That Influence Substance Use Among American Indian/Alaskan Native Youth: A Systematic Mixed Studies Review

BACKGROUND

The American Indian/Alaskan Native (AI/AN) mortality rate from illicit drug use was 22.7%, double that of the general population between 2007 and 2009. Fifteen percent of AI/AN youth reported receiving treatment for substance use compared with 10% of non-AI/AN peers.

OBJECTIVE

The purpose was to explore the factors that influence substance use among AI/AN youth.

METHOD

We performed a systematic review using a results-based convergent synthesis design. Eight electronic databases were searched for articles published between 2014 and 2019 using the search terms "Native American youth," "Native American adolescent," "Native Youth," "substance use," "substance misuse," and "substance abuse." The Mixed Methods Appraisal Tool was used to appraise the studies.

RESULTS

Forty-seven studies met the inclusion criteria (44 quantitative, one qualitative, and two mixed-methods studies). The results were organized using the ecological systems model and included evaluation of both protective and risk factors related to AI/AN youth substance use. Three system levels were found to influence substance use: individual, micro- and macrosystems. The individual systems-level coping mechanisms played a key role in whether AI/AN youth initiated substance use. Family, school, and peer factors influence the microsystem level. At the macrosystem level, community environmental factors were influential.

CONCLUSION

The major factor linking all the systems was the influence of a connected relationship with a prosocial adult who instilled future aspirations and a positive cultural identity. Findings of this systematic mixed studies review will assist in intervention development for AI/AN youth to prevent substance misuse.

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.

Conjoint adolescent developmental trajectories of alcohol and marijuana use and early adult outcomes among North American Indigenous people

OBJECTIVE

The current study examined the developmental interrelationships between alcohol and marijuana use trajectories from ages 10 to 18 years in a sample of North American Indigenous adolescents. Distinct co-use groups were formed to create profiles of young adult outcomes.

METHOD

Dual group-based trajectory models of marijuana and alcohol frequency were estimated using data from a longitudinal community-based participatory study of Indigenous adolescents from the upper Midwest and Canada. Joint probabilities were used to create co-use groups, and profiles were created using early adult (Mean Age - 26.28 years) outcomes.

RESULTS

Four joint trajectory groups were identified: 1) no marijuana and no/low alcohol use (34.4%), 2) mid-onset alcohol only (14%), 3) mid-onset co-use starting at age 13 (24%), and 4) early-onset co-use starting at age 11 (22%). High probabilities existed that adolescents would use marijuana early if they began drinking alcohol at the youngest ages, and that adolescents would not use marijuana if they drank infrequently or delayed drinking until mid-adolescence. Adult outcomes were poorer for the early- and mid-onset co-use groups, but there were few differences between the no/low use and alcohol-only groups.

CONCLUSION

Co-use of marijuana and alcohol was associated with poorer outcomes in early adulthood, particularly for the group with an earlier age of onset. Abstaining from either substance in adolescence was associated with better outcomes.

Drug addiction co-morbidity with alcohol: Neurobiological insights

Addiction is a chronic disorder that consists of a three-stage cycle of binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation. These stages involve, respectively, neuroadaptations in brain circuits involved in incentive salience and habit formation, stress surfeit and reward deficit, and executive function. Much research on addiction focuses on the neurobiology underlying single drug use. However, alcohol use disorder (AUD) can be co-morbid with substance use disorder (SUD), called dual dependence. The limited epidemiological data on dual dependence indicates that there is a large population of individuals suffering from addiction who are dependent on more than one drug and/or alcohol, yet dual dependence remains understudied in addiction research. Here, we review neurobiological data on neurotransmitter and neuropeptide systems that are known to contribute to addiction pathology and how the involvement of these systems is consistent or divergent across drug classes. In particular, we highlight the dopamine, opioid, corticotropin-releasing factor, norepinephrine, hypocretin/orexin, glucocorticoid, neuroimmune signaling, endocannabinoid, glutamate, and GABA systems. We also discuss the limited research on these systems in dual dependence. Collectively, these studies demonstrate that the use of multiple drugs can produce neuroadaptations that are distinct from single drug use. Further investigation into the neurobiology of dual dependence is necessary to develop effective treatments for addiction to multiple drugs.

Latent Trajectories and Profiles of Commercial Cigarette Smoking Frequency From Adolescence to Young Adulthood Among North American Indigenous People

INTRODUCTION

North American Indigenous people (ie, American Indian/Alaska Native and Canadian First Nations) have the highest rates of commercial cigarette smoking, yet little is known about long-term trajectories of use among this population. The purpose of this study is to examine heterogeneous trajectories and profiles of Indigenous cigarette use frequency from early adolescence (mean age: 11.1 years) to young adulthood (mean age: 26.3 years).

AIMS AND METHODS

Data come from a nine-wave prospective longitudinal study spanning early adolescence through young adulthood among Indigenous people in the Upper Midwest of the United States and Canada (N = 706). Smoking frequency was examined at each wave, and latent class growth analysis was used to examine heterogeneous patterns. Early adolescent and young adult demographics and smoking-related characteristics were examined across these latent trajectory groups.

RESULTS

In young adulthood, 52% of participants smoked daily/near-daily, and an additional 10% smoked weekly or monthly. Four latent trajectory groups emerged: low/non-smokers (35.2%) who had low probabilities of smoking across the study; occasional smokers (17.2%) who had moderate probabilities of smoking throughout adolescence and declining probabilities of smoking into young adulthood; mid-adolescent onset smokers (21.6%) who showed patterns of smoking onset around mid-adolescence and escalated to daily use in young adulthood; and early-adolescent onset smokers (25.9%) who showed patterns of onset in early adolescence and escalated to stable daily use by late adolescence.

CONCLUSIONS

The findings suggest multiple critical periods of smoking risk, as well as a general profile of diverse smoking frequency patterns, which can inform targeted intervention and treatment programming.

IMPLICATIONS

Nearly two-thirds (62%) of this sample of Indigenous people were current smokers by early adulthood (mean age = 26.3 years), which is substantially higher than national rates in the United States and Canada. Moreover, in all but one trajectory group, smoking prevalence consistently increased over time, suggesting these rates may continue to rise into adulthood. The longitudinal mixture modeling approach used in this study shows that smoking patterns are heterogeneous, and implications for public health policy likely vary across these diverse patterns characterized by timing of onset of use, escalation in frequency of use, and stability/change over time.

A systematic review of electronic mental health interventions for Indigenous youth: Results and recommendations

Electronic health interventions involve health services delivered using the Internet and related communication technologies. These services can be particularly relevant for Indigenous populations who often have differential access to health-care services compared to general populations, especially within rural and remote areas. As the popularity of electronic health interventions grows, there is an increased need for evidence-based recommendations for the effective use of these technologies. The current study is a systematic review of peer-reviewed and available grey literature with the aim of understanding outcomes of electronic health interventions for mental health concerns among Indigenous people. Studies used electronic health technologies for substance use treatment or prevention, suicide prevention, parenting supports, goal setting and behaviour change and consultation services. Various technological platforms were used across interventions, with both novel and adapted intervention development. Most studies provided qualitative results, with fewer studies focusing on quantitative outcomes. Some preliminary results from the engagement of Indigenous individuals with electronic health services has been demonstrated, but further research is needed to confirm these results. Identified barriers and facilitators are identified from the reviewed literature. Recommendations for future development of electronic health interventions for Indigenous youth are provided.

Easing the disruption of COVID-19: supporting the mental health of the people of Canada—October 2020—an RSC Policy Briefing

The COVID-19 pandemic has had a significant impact on the mental health of the people of Canada. Most have found it challenging to cope with social distancing, isolation, anxiety about infection, financial security and the future, and balancing demands of work and home life. For some, especially those who have had to face pre-existing challenges such as structural racism, poverty, and discrimination and those with prior mental health problems, the pandemic has been a major impact.

The Policy Briefing Report focuses on the current situation, how the COVID-19 pandemic has exacerbated significant long-standing weaknesses in the mental health system and makes specific recommendations to meet these challenges to improve the well-being of the people of Canada.

The COVID-19 pandemic has had a detrimental effect on mental health of people in Canada but the impact has been variable, impacting those facing pre-existing structural inequities hardest. Those living in poverty, and in some socially stratified groups facing greater economic and social disadvantage, such as some racialized and some Indigenous groups and those with preexisting mental health problems, have suffered the most. Some occupational groups have been more exposed to the virus and to psychological stress with the pandemic. The mental health care system was already overextended and under resourced. The pandemic has exacerbated the problems. The care system responded by a massive move to virtual care. The future challenge is for Canada to strengthen our knowledge base in mental health, to learn from the pandemic, and to provide all in Canada the support they need to fully participate in and contribute to Canada’s recovery from the pandemic.

Association between experience of racial discrimination and hazardous alcohol use among Māori in Aotearoa New Zealand

AIMS

To test whether there is a positive association between experience of racial discrimination and hazardous alcohol use among New Zealand Māori and whether racial discrimination mediates hazardous alcohol use in this group.

DESIGN

A cross-sectional mediation analysis using a stratified and nationally representative cross-sectional health survey collected from 2016 to 2017 in New Zealand.

SETTING

New Zealand.

PARTICIPANTS

We used data from 9884 participants who identified as New Zealand European (7341; 56.9% female) or Māori (2543; 60.5% female) in the 2016-17 New Zealand Health Survey.

MEASUREMENTS

We included reports from demographic items (sex, age, ethnicity), the Alcohol Use Disorder Identification Test (AUDIT) and experiences of past year discrimination. We conducted mediation analysis with Māori identification as the predictor, hazardous drinking as the binary outcome (0 = AUDIT score less than 8, 1 = 8+) and discrimination as the binary mediator (0 = no discrimination, 1 = experienced racial discrimination). Age, sex and deprivation index were included as covariates.

FINDINGS

Māori were more likely to experience discrimination than New Zealand Europeans, and both Māori identification and experiencing discrimination were associated with elevated levels of hazardous alcohol use, P < 0.05. The association between Māori ethnicity on hazardous drinking was partially mediated by discrimination (34.7%, 95% confidence interval 9.70%, 59.60%).

CONCLUSION

The association between Māori ethnicity and hazardous drinking in New Zealand may be partially mediated by experience of discrimination.
