Socioeconomic inequalities in psychological distress and suicidal behaviours among Indigenous peoples living off-reserve in Canada

Unravelling Suicide and Related Behaviours in Indigenous Youth and Young Adults in the Canadian Context

Suicide, rooted in antiquity, is now identified as a global dilemma, particularly impacting Indigenous peoples. The backdrop for this non-systematic focused review is the worldwide challenges faced by vulnerable Indigenous peoples with untenable poverty, degraded life-quality conditions, and suicidality, while the focus, as a specific case, is on the complexity of suicidality in Canadian Indigenous high-risk age groups. The aim here is to present overt and covert intersecting factors underlying suicide in Indigenous youths and young adults in the vast Canadian context. Although living in a privileged geopolitical region, their physically remote and economically compromised communities meshed with a haunting history combined with authorities' ingrained attitudes of exclusion and neglect, spawned meager health and education resources, services, and consequent dire results. The article's guiding theoretical frameworks are Transcultural Psychiatry with its emphasis on context that explains health, illness, and recovery in groups and individuals, and the Interpersonal Psychological Theory of Suicide to identify individuals' suicidality triggers. The article highlights indigenous social determinants of health, identifies elements underlying the tragic suicidality trend in these groups, and addresses literacy and education as poverty driven issues and suicidality-contributing factors promoting attitudes of hopelessness. The discussion includes joint suicide combatting efforts by Indigenous communities and Canadian authorities, these authors' psychosocial-cognitive literacy acquisition plan to address all age-groups simultaneously, and a take-home message introducing employers' desirable worker competencies for effective future employment, thereby uplifting life-quality and prospects to help thwart the spectre of suicide. The Conclusion introduces current trends in suicidality science, confirming the authors' intervention plan is a good fit in the psychosocial intervention trend. Future directions include advice to examine the effectiveness of the plan in the Indigenous context, and tweak it accordingly. For ease of reader comprehension, the article flow is included at the start of the Introduction section.

Mental health and cultural continuity among an urban Indigenous population in Toronto, Canada

OBJECTIVES

Mental health and psychiatric disorders significantly affect individuals on personal and social levels. Indigenous populations in Canada have disproportionately high rates of mental health diagnoses. Our Health Counts (OHC) Toronto assessed mental health, racism, family disruption, and cultural continuity among urban Indigenous people. The objectives of this study were to understand (1) the demographics and characteristics of Indigenous adults with a diagnosed psychological/mental health disorder and (2) potential associations of psychological/mental health diagnoses with experiences of colonization and cultural continuity among Indigenous adults in Toronto.

METHODS

Using community-based participatory research methods, Indigenous adults in Toronto were recruited by respondent-driven sampling (RDS) to complete a comprehensive health assessment survey. RDS-II weights were applied to calculate population-based estimates, and adjusted odds ratios with 95% confidence intervals were produced using logistic regression, controlling for age and gender.

RESULTS

Among Indigenous adults, nearly half (45%) reported receiving a mental health diagnosis. Participants reported lifetime anxiety disorders (53%), major depression (51%), and high rates of suicide ideation (78%). Of Indigenous adults with a diagnosed mental health disorder, 72.7% reported participating in ceremony. Attending residential schools (OR: 7.82) and experiencing discrimination (OR: 2.69) were associated with having a mental health disorder.

CONCLUSION

OHC Toronto responded to the gaps in health assessment data for urban Indigenous people. Despite historic and ongoing trauma, Indigenous people have maintained cultural practices and a strong sense of identity. Efforts aimed at supporting Indigenous well-being must respond to the roots of trauma, racism, and existing Indigenous community knowledge and strengths.

Focusing attention on the important association between food insecurity and psychological distress: a systematic review and meta-analysis

BACKGROUND

Food insecurity has involved more than 750 million individuals worldwide. The association of food insecurity with socio-economic factors is also undeniable demand more consideration. Food insecurity will become a global priority by 2030. This systematic review and meta-analysis examined current literature concerning the association between food insecurity and psychological distress.

METHODS

Relevant researches were identified by searching databases including PubMed, EMBASE, Scopus, and Web of Science, ProQuest, and Cochrane Library up to June 2024 without language limitation. Then a snowball search was conducted in the eligible studies. The quality assessment was made through Newcastle-Ottawa Scale.

RESULTS

Data were available from 44 cross-sectional articles for systematic review and 17 eligible articles for meta-analysis with 2,267,012 and 1,953,636 participants, respectively. Findings support the growing segment of literature on the association between food insecurity and psychological distress. The highly represented groups were households with low income. Psychological and diabetic distress was directly associated with food insecurity as it increased the odds of distress to 329% (OR: 3.29; 95% CI: 2.46-4.40). Sleep problems, anxiety, depression, lower life satisfaction, obesity, and a higher rate of smoking were among the secondary outcomes.

CONCLUSION

Food insecurity was a common stressor that can have a negative impact on psychological well-being and even physical health. The findings should be considered in the public health and making policy-making process.

Food insecurity as a mediator and moderator in the association between residential mobility and suicidal ideation among Indigenous adults in Canada

PURPOSE

Despite a growing body of literature on the link between residential mobility and suicidal ideation, research into potential mediating or moderating factors, especially among socioeconomically disadvantaged populations, is sparse. This study explores the mediating and moderating roles of food insecurity in the relationship between residential mobility and suicidal ideation in Indigenous Canadian adults.

METHODS

Data from the 2017 Aboriginal Peoples Survey, which represent a national sample of off-reserve First Nations peoples, Métis, and Inuit in Canada (N = 16,214), were analyzed using logistic regression models.

RESULTS

Food insecurity partially mediated the association between residential mobility in the past 5 years and increased suicidal ideation risk among Indigenous adults. Moreover, food insecurity intensified the adverse link between residential mobility during this same timeframe and suicidal ideation. Yet, while food insecurity did mediate the adverse relationship between residential mobility in the past year and suicidal ideation, it did not function as a moderator.

CONCLUSION

The results emphasize that food insecurity, as a systemic challenge, acts as both a partial mediator and, in some circumstances, an amplifier of the detrimental impacts of residential mobility on suicidal ideation.

Interplay between actual and perceived weight on mental health among Canadian Indigenous post-secondary students

OBJECTIVES

Research increasingly focuses on the mental health implications of both actual and perceived weight, particularly among post-secondary students. Considering their unique socio-cultural context and the frequent oversight in research, this study examines these implications specifically among Canadian Indigenous post-secondary students. Recent evidence indicates that students with normal weight may also experience increased mental health risks due to negative weight perceptions. Therefore, this study explores the independent and combined effects of actual and perceived weight on the mental health of this group.

PARTICIPANTS AND METHODS

This study utilized data from the 2017 Aboriginal Peoples Survey, a nationally representative sample of First Nations peoples living off-reserve, Métis, and Inuit. The focus was on Canadian Indigenous post-secondary students aged 19-34 years (n = 1,518). Logistic regression models, stratified by sex, were employed to analyze the data.

RESULTS

Perceptions of being overweight were linked to a higher risk of mood and anxiety disorders, poor self-rated mental health, and suicidal ideation among female students. This pattern was less evident among male students. Notably, female students who were overweight and perceived themselves as such were more likely to report poor mental health across all four indicators examined. In contrast, male students exhibited a less clear pattern. Diverging from recent studies, the findings indicated less robust mental health disparities among students with normal weight who perceived themselves as overweight, potentially due to the insufficient cell size of this category among Indigenous post-secondary students.

CONCLUSIONS

The study highlights the complex interplay between actual and perceived weight and its impact on mental health, particularly among female Indigenous post-secondary students.

Effect of Socioeconomic Disparities on Suicide Risk in Patients With Prostate Cancer During 2005 to 2020: A Population Study

PURPOSE

To determine whether socioeconomic disparities have an impact on the likelihood of suicide among prostate cancer patients.

METHODS

Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) database for patients diagnosed with malignant prostate cancer between 2005 and 2020. The socioeconomic disparities of the patients were evaluated by median household income (MHI) and ethnicity. Ethnicity included Spanish-Hispanic-Latino and non-Spanish-Hispanic-Latino. A Cox proportional risk model was utilized. Using the Kaplan-Meier approach, the cumulative incidence of suicide mortality was measured.

RESULTS

A total of 857,418 US population with prostate cancer were included. In the multivariate analysis, individuals with MHI over $75,000 had a lower risk of suicide mortality than those with MHI between $54,999 and $74,999 in all patients (aHRs: 0.693, 95 CI%: 0.603-0.797). Spanish-Hispanic-Latino displayed lower overall suicide mortality in all patients (aHRs: 0.426, 95% CI: 0.323-0.561). In the subgroup analysis of different ages, individuals with MHI over $75,000 had a lower risk of suicide than those with MHI between $54,999 and $74,999 in patients 60 to 79 years (aHRs: 0.668, 95% CI: 0.562-0.794) and individuals with MHI below $54,999 had higher suicide risk than those with MHI between $54,999 and $74,999 in patients 80+ years (aHRs: 1.786, 95% CI: 1.100-2.902). Hispanic-Latino individuals had lower overall suicide mortality in 00 to 59 years (aHRs: 0.420, 95% CI: 0.240-0.734), 60 to 79 years (aHRs: 0.445, 95% CI: 0.319-0.621), 80+ years (aHRs: 0.363, 95% CI: 0.133-0.988).

CONCLUSION

Socioeconomic disparities, including MHI and ethnicity, are important factors strongly related to suicide risk in prostate cancer patients. The lower MHI individuals and non-Spanish-Hispanic-Latino individuals were associated with higher suicide risk.

Food insecurity and its association with multiple health outcomes among Indigenous peoples in Canada: the buffering role of culture-based resources

OBJECTIVES

Despite growing interest in the health disparities associated with food insecurity, research focusing on Indigenous peoples has been limited, especially in studies using nationally representative samples. This study investigates the association between food insecurity and various health outcomes - self-rated general and mental health, chronic health conditions, suicidal ideation, and obesity - among Indigenous peoples in Canada. It also explores the potential moderating effects of culture-based resources, which include cultural identity affect, cultural group belonging, cultural engagement, and cultural exploration.

DESIGN

The study utilized data from the 2017 Aboriginal Peoples Survey, a nationally representative sample of First Nations individuals living off-reserve, Métis, and Inuit across Canada (N = 15,533). Logistic regression models were used to analyze the data.

RESULTS

Food insecurity was negatively associated with all examined health outcomes. Culture-based resources demonstrated a mixture of anticipated and unexpected effects on these relationships. Consistent with the stress process model, cultural group belonging mitigated the negative impact of food insecurity on all health outcomes. A similar pattern was observed for cultural engagement. However, contrary to expectations from the stress-buffering perspective, little evidence was found to support the moderating effects of cultural identity affect and cultural exploration.

CONCLUSION

The results underscore the detrimental effects of food insecurity on the health of Indigenous peoples in Canada and suggest that culture-based resources, particularly cultural group belonging, play a crucial role in mitigating health disparities.

The methods of improving cultural sensitivity of depression scales for use among global indigenous populations: a systematic scoping review

Cultural adaptation of psychometric measures has become a process aimed at increasing acceptance, reliability, and validity among specific Indigenous populations. We present a systematic scoping review to: (1) identify the depression scales that have been culturally adapted for use among Indigenous populations worldwide, (2) globally report on the methods used in the cultural adaptation of those scales, and (3) describe the main features of those cultural adaptation methods. We included articles published from inception to April 2021, including 3 levels of search terms: Psychometrics, Indigenous, and Depression. The search was carried out in the Ovid Medline, PubMed, Embase, Global Health, PsycINFO, and CINAHL databases, following PRISMA guidelines. We identified 34 reports on processes of cultural adaptation that met the criteria. The scales were adapted for use among Indigenous populations from Africa, Australia, Asia, North America, and Latin America. The most common scales that underwent adaptation were the Patient Health Questionnaire (PHQ-9), the Center for Epidemiologic Studies Depression Scale (CES-D), and the Edinburgh Postnatal Depression Scale (EPDS). Methods of adaptation involved a revision of the measures' cultural appropriateness, standard/transcultural translation, revision of the administration process, and inclusion of visual supports. Culturally safe administration of scales was reported in some studies. To come to a consensus on most appropriate methods of improving cultural safety of psychometric measurement, most studies utilized qualitative methods or mixed methods to understand the specific community's needs. Revision of linguistic equivalence and cultural relevance of content, culturally safe administration procedures, qualitative methods, and participatory research were key features of developing safe culturally adapted measures for depressive symptoms among Indigenous populations. While for comparability, uniform scales would be ideal as mental health evaluations, an understanding of the cultural impact of measurements and local depression expressions would benefit the process of developing culturally sensitive psychometric scales.

Mental Health Challenges Among First Nations Adolescents Living Off-Reserve in Ontario, Canada

Limited data exist on the mental health challenges facing First Nations adolescents and the factors that modify these difficulties. The current study compared levels of common mental health challenges among 112 off-reserve First Nations and 3334 non-First Nations adolescents (12-17 years old) and examined the impact of maternal psychological distress on these mental health challenges. First Nations adolescents self-reported higher symptoms of conduct, oppositional-defiant, attention-deficit hyperactivity, major depressive, social phobia, generalized anxiety, and separation anxiety disorders and all associations remained statistically significant after adjusting for covariates. Moderation analyses found that increasing levels of maternal distress were associated more strongly with symptoms of oppositional defiant, attention-deficit hyperactivity, major depressive, and generalized anxiety disorders in First Nations adolescents. Future work aimed at improving the mental health of First Nations youth that focus on supporting these adolescents, and their mothers in particular, could result in substantial benefits.

Housing as a determinant of Inuit mental health: associations between improved housing measures and decline in psychological distress after rehousing in Nunavut and Nunavik

INTERVENTION

In 2014-2015, more than 400 public housing units were constructed in Nunavut and Nunavik, two of the four Inuit regions in Canada. This provided the opportunity to assess the impact of improved housing conditions from a population health perspective in 12 Inuit communities where housing needs were the most severe. The aim of the research is to examine the associations between changes in housing conditions and changes in psychological distress pre-post rehousing.

METHODS

A pre-post uncontrolled study was conducted in collaboration with Nunavut- and Nunavik-based organizations. Applicants at the top of public housing waitlists were recruited by local housing officers; participants completed questionnaires 1-6 months before rehousing, and 15-18 months after. Change in psychological distress was measured with the Kessler 6-item scale. Changes in three housing measures were examined: number of adults per household, number of children per household, and sense of home score. For each housing measure, a categorical variable stratified participants into three categories. The reference category included participants reporting significant change in the concerned housing measure; the two other categories included participants reporting little or no change. Associations were tested with linear multilevel regression models for change.

RESULTS

A total of 102 Inuit adults completed the study. A reduction in the number of adults per household (living with 2 adults or less after rehousing) and an increase in sense of home were associated with significant decline in psychological distress pre-post rehousing (p < 0.001).

CONCLUSION

Increased investments leading to such improvements in housing circumstances are promising ways to promote mental health in Inuit regions.

A national-level examination of First Nations peoples’ mental health data: Predicting mental well-being from social determinants of health using the 2017 Aboriginal Peoples Survey

Introduction

A history of colonization and assimilation have resulted in social, economic, and political disparities for Indigenous people in Canada. Decades of discriminatory policies (e.g., the Indian Act, the Residential School System) have led to numerous health and mental health inequities, which have been intergenerationally maintained. Four main social determinants of health (i.e., income, education, employment, and housing) disproportionately influence the health of Indigenous peoples. These four social determinants have also been used within the Community Well-Being (CWB) index, which assesses the socio-economic wellbeing of a community. This study sought to extend previous research by assessing how specific indicators of CWB predict self-reported mental wellbeing within First Nations populations across Canada in a national dataset with more recent data.

Methods

This study utilized the 2017 Aboriginal Peoples Survey, which includes data on the social and economic conditions of First Nations people living off reserve aged 15 years and over.

Results

Results from a factorial ANOVA indicated that perceptions of income security, housing satisfaction, higher education, and employment are associated with increased self-reported mental health among First Nations individuals living off-reserve.

Discussion

These results support the idea that individual mental health interventions on their own are not enough; instead, broader social interventions aimed at addressing inequities in various social determinants of health (e.g., housing first initiatives) are needed to better support individual wellbeing.

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.

"We're Home Now": How a Rehousing Intervention Shapes the Mental Well-Being of Inuit Adults in Nunavut, Canada

This study explores the ways in which a rehousing intervention shapes the mental well-being of Inuit adults living in Nunavut, Canada, where the prevalence of core housing need is four times the national average. More specifically, it compares the housing experiences of participants who were rehoused in a newly built public housing unit, to the experiences of participants on the public housing waitlist. The study was developed in collaboration with organizations based in Nunavut and Nunavik. Semi-structured interviews were transcribed, and a deductive-inductive thematic analysis was performed based on Gidden's concept of ontological security, and Inuit-specific mental health conceptualization. Twenty-five Inuit adults participated (11 rehoused, 14 waitlist). Three themes were identified to describe how the subjective housing experiences of participants improved their mental well-being after rehousing: (1) refuge creation; (2) self-determination and increased control; (3) improved family dynamics and identity repair. Implicit to these themes are the contrasting housing experiences of participants on the waitlist. Construction initiatives that increase public housing stock and address gaps in the housing continuum across Inuit regions could promote well-being at a population level. However, larger socio-economic problems facing Inuit may hamper beneficial processes stemming from such interventions.

Suicidal behavior in Mexican adolescents: A test of a latent class model using two independent probability samples

Suicidal behavior is a serious health issue that affects the adolescent population and that may be prevented through evidence-based approaches. There are many risk factors involved in suicidal behavior, but there are few studies encompassing the complex relationships between them. This study tested the similarity between two latent class models from two different epidemiological samples of middle-school students and evaluated if the multinomial regression model replicated the associations between the classes and the psychosocial variables. Data of 4013 adolescents from the Mexican states of Campeche and Querétaro were included in LCA to characterize suicide behavior and associated factors. The most likely latent class membership was used as the outcome in multinomial regression models. The model with data from Querétaro was consistent with the previous LC model from Campeche. The four latent classes were nearly identical for both populations and can be defined as follows: 1) "No Problems," included 73% of the adolescents; 2) "Drug Use Only," comprised 7% of the adolescents; 3) "Suicidal Behavior, No Depression," captured 8% of the adolescents (25% reported binge drinking in the past month, 50% self-inflicted injuries, and 43% low-lethality suicide attempt); 4) "Depression and Suicidal Behavior," comprised 12% of the sample (66% met criteria for Major Depressive Episode, 28% reported binge drinking in the past month, and 11% had a high-lethality suicide attempt). The congruence between the models and the consistency with identified factors highlight the need for appropriate and effective prevention strategies to minimize risk factors and reinforce protective factors in the adolescent population.

Changes After Emergency Assessment of Suicidal Patients: An Unexpected Outcome

INTRODUCTION

Acute Suicide Risk (ASR) is widely evaluated at Emergency Departments (ED). Little is known about follow-up of ASR after psychiatric ED evaluation, and if there are differences within No ASR (NASR) counterparts at baseline and afterwards.

METHOD

We developed a naturalistic, 3-month follow-up study of adult patients from a psychiatric ED in Mexico City. Depressive patients who asked voluntarily for an emergency consultation from July 1 to December 1, 2014, were included. We compared depression severity, suicidal ideation, adherence to treatment, and perceived social support scales both in ASR and NASR participants at baseline and follow-up interviews.

RESULTS

Participants (n = 120) were divided into ASR or NASR groups (n = 60 each). The ASR group obtained more negative scores in all scales at baseline evaluation. After three months, 85% (n = 51) of ASR and 75% (n = 45) of NASR completed the second interview. 5.21% (n = 3) of participants showed new suicidal behavior. At follow-up, the ASR group showed a higher relative response in depression scales and treatment adherence (p = 0.036), and lower scores in suicidal ideation scales than NASR group (p = 0.012). Perceived support from family was significantly higher in the NASR group (p = 0.016).

DISCUSSION

These relative higher responses in clinical scales suggest a paradoxical advantage of ASR over NASR patients, suggesting a hypothetical phenomenon similar to "The Tortoise and the Hare" effect. However, it is not applicable for all ASR patients. Results suggest suicidal patients experience stigma from their families. Further research and public health programs for ASR at ED should be implemented.

Regional and socioeconomic disparities in cardiovascular disease in Canada during 2005-2016: evidence from repeated nationwide cross-sectional surveys

Introduction

The objective of this study is to examine the temporal trends and patterns of regional and socioeconomic disparities in cardiovascular disease (CVD) in Canada during 2005–2016.

Methods

A total of 670 000 adults aged ≥20 years who participated in the Canadian Community Health Surveys between 2005 and 2016 were enrolled for this study. CVD referred to heart disease and stroke in this study. Equivalised household income was used as a proxy of socioeconomic status. Absolute and relative socioeconomic inequalities were measured by slope index of inequality (SII) and relative index of inequality (RII), respectively.

Results

In 2015/2016, the overall age-adjusted and sex-adjusted prevalence of heart disease and stroke was 4.80% (95% CI 4.61% to 4.98%) and 1.25% (95% CI 1.13% to 1.36%), respectively. Trend analyses suggested a significant decline in the age-adjusted and sex-adjusted prevalence of heart disease (P for trend <0.001) and a non-significant decline in the age-adjusted and sex-adjusted prevalence of stroke (P for trend=0.058) from 2005 to 2016. Nevertheless, the total number of adults suffering from heart disease and stroke increased by 8.9% and 20.2% over the study period, respectively. Moreover, the age-adjusted and sex-adjusted prevalence of heart disease and stroke varied widely across all health regions, and both of them tended be higher among those with lower income. The SII and RII indicated that there were persistent absolute and relative socioeconomic inequalities in heart disease and stroke across all surveys (eg, SII for heart disease in both sexes, 2005: 0.04 (95% CI 0.03 to 0.04); 2015/2016: 0.03 (95% CI, 0.02 to 0.04); RII for heart disease in both sexes, 2005: 1.99 (95% CI 1.75 to 2.27); 2015/2016: 1.77 (95% CI 1.52 to 2.08).

Conclusion

Geographical and socioeconomic disparities should be taken into account during the further efforts to strengthen preventive measures and optimise healthcare resources for heart disease and stroke in Canada.

Demographics of mental healthcare presentations in a northwest Ontario emergency department

OBJECTIVES

Providing emergency mental health services for populations in remote rural areas of Canada is challenging. Program needs are distinct. We describe the emergency mental health workload and service needs at the Sioux Lookout Meno Ya Win Health Centre (SLMHC) in northwest Ontario.

METHODS

Emergency department (ED) data were collected for mental health, addiction and self-harm diagnoses (MHA) in 2018/2019. Comparisons were made to similar sized provincial hospitals and EDs. Mental health admissions data from Oct 1, 2018 to Dec 31, 2019 were manually collected from hospital medical charts for demographics, suicide attempts/ideation and frequency of applications for Form 1 psychiatric assessment.

RESULTS

The volume of MHA ED visits as a percentage of total ED visits was 4 times higher at SLMHC when compared to both the 67 other Ontario level C hospitals (< 100 beds) and the 15 level C hospital with a similar volume of ED visits (15,000-20,000), (15% vs 4%). Self-harm presentations were 308 at SLMHC versus an average of 42 ± 37 at the 15 level C hospitals with a similar ED volume. From Oct 1, 2019 to Dec 31, 2019, there were 49 patients requiring a Form 1, with an average wait time of 55 h before transfer to a schedule 1 facility.

CONCLUSION

There is an increased level of mental health, addiction and self-harm presentations in this northern ED. Lack of alternative resources indicate the need for the development of an integrated model of mental health care service. Reliance on the ED for crisis management indicates the need for the development of more regionally relevant models of care.

Trends and Regional Variation in Prevalence of Cardiovascular Risk Factors and Association With Socioeconomic Status in Canada, 2005-2016

IMPORTANCE

Cardiovascular disease remains the second leading cause of death in Canada. Monitoring and tracking the trends and disparities in major cardiovascular risk factors could provide benchmarks for future cardiovascular health strategies.

OBJECTIVE

To investigate the temporal trends, regional variations, and socioeconomic disparities in major cardiovascular risk factors in Canada from 2005 to 2016.

DESIGN, SETTING, AND PARTICIPANTS

This repeated cross-sectional survey study included adults aged 20 years and older from 6 Canadian Community Health Survey cycles between 2005 and 2016. Cardiovascular risk factors included hypertension, diabetes, obesity, and current smoking. Socioeconomic status was measured using equivalized household income. Data analysis was performed from September 2019 to April 2020.

EXPOSURES

A total of 112 health regions and socioeconomic status.

MAIN OUTCOMES AND MEASURES

Age- and sex-adjusted prevalence of hypertension, diabetes, obesity, and current smoking by year; health regions; and socioeconomic status. Absolute numbers were rounded to base 100 for confidentiality purposes, and percentages were based on weighted numbers. Slope index of inequality (SII) and relative index of inequality (RII) were calculated to assess absolute and relative socioeconomic inequalities, respectively.

RESULTS

A total of 670 000 respondents (329 000 [49.1%] men; 341 000 [50.9%] women) aged 20 years and older from 6 survey cycles were enrolled for this study. The largest age group was those aged 40 to 59 years (eg, 2005 cycle: 40.2% [95% CI, 39.9%-40.6%]). In the 2015/2016 cycle, the overall age- and sex-adjusted prevalence rates of hypertension, diabetes, obesity, and current smoking were 20.7% (95% CI, 20.4%-21.1%), 7.2% (95% CI, 7.0%-7.5%), 20.1% (95% CI, 19.7%-20.6%), and 17.8% (95% CI, 17.4%-18.2%), respectively. From 2005 to 2016, there was a significant increase in the prevalence of hypertension, diabetes, and obesity (eg, prevalence of diabetes in both sexes, 2005: 5.8% [95% CI, 5.6%-6.0%]; 2015/2016: 7.2% [95% CI, 7.0%-7.5%]; P < .001) but a significant decrease in the prevalence of current smoking (both sexes, 2005: 22.1% [95% CI, 21.7%-22.5%]; 2015/2016: 17.8% [95% CI, 17.4%-18.2%]; P < .001). The prevalence of all the risk factors varied widely across health regions (eg, obesity, Vancouver Health Service Delivery Area: 6.7% [95% CI, 4.5%-9.0%]; Miramichi Area: 36.8% [95% CI, 27.3%-46.3%]). In addition to obesity among men, all risk factors tended to be more common among those with lower income (eg, prevalence of hypertension in both sexes, 2015/2016, lowest income group: 23.2% [95% CI, 22.4%-24.0%]; highest income group: 18.4% [95% CI, 17.7%-19.1%]). The SII and RII indicated consistent absolute and relative socioeconomic inequalities in hypertension, diabetes, and current smoking over time (eg, RII for hypertension in both sexes, 2005: 1.25; 95% CI, 1.18-1.33; 2015/2016: 1.34; 95% CI, 1.26-1.43). However, the phenomenon of absolute and relative socioeconomic inequalities in obesity was only observed among women (eg, RII for 2015/2016 for obesity in women; 1.74 (95% CI, 1.56-1.93); men: 1.09; 95% CI, 0.99-1.21).

CONCLUSIONS AND RELEVANCE

During the study period, the prevalence of hypertension, diabetes, and obesity significantly increased, while the prevalence of current smoking significantly decreased. Geographic and socioeconomic gaps should be considered and addressed in future interventions and policies targeted at reducing these cardiovascular risk factors in Canada.

Segmenting or Summing the Parts? A Scoping Review of Male Suicide Research in Canada

OBJECTIVE

Suicide in Canadian men is high and rising. Research consistently indicates increased suicide risk in male subgroups including sexual minority, Indigenous, middle-aged, and military men. The current scoping review addresses the research question: Among male subgroups featured in Canadian suicide research, what are the key findings to inform suicide prevention efforts?.

METHOD

A scoping review was undertaken in accord with PRISMA-ScR guidelines. Structured searches were conducted in CIHAHL, Medline, PsychInfo, and Web of Science to identify studies reporting suicidality (suicidal ideation, plans and/or attempts) and suicide among men in Canada. Inclusion criteria comprised primary empirical studies featuring Canadian male subgroups published in English from 2009 to 2020 inclusive.

RESULTS

Sixty-eight articles met the inclusion criteria, highlighting significant rates of male suicidality and/or suicide in 3 categories: (1) health inequities (n = 29); (2) age-specific (n = 30); and (3) occupation (n = 9). The health inequities category included sexual minority men, Indigenous, and other marginalized males (i.e., homeless, immigrant men, and men who use opiates). Age-specific men focused on adolescents and youth, and middle-aged and older males. Active military, veterans, and first responders featured in the occupation category. Studies compared at risk male subgroups to females, general male populations, and/or other marginalized groups in emphasizing mental health disparities and increased suicide risk. Some men's suboptimal connections to existing mental health care services were also highlighted.

CONCLUSION

While male subgroups who are vulnerable to suicidality and suicide were consistently described, these insights have not translated to tailored upstream suicide prevention services for Canadian boys and men. There may be some important gains through integrating social and mental health care services for marginalized men, implementing school-based masculinity programs for adolescent males, orientating clinicians to the potential for men's mid-life suicide risks (i.e., separation, bereavement, retirement) and lobbying employers to norm help-seeking among activate military, veterans, and first responder males.

The intergenerational effects of socioeconomic inequality on unhealthy bodyweight

We study the effects of inherited socioeconomic characteristics on markers of unhealthy bodyweight. Taking Australian microdata from 2007 to 2013, we show that approximately 4% of the variation in outcomes is determined by factors beyond an individual's control, such as their race, gender, and social class. Paternal socioeconomic status is the primary explanatory factor, with those born to more affluent fathers slightly less likely to be overweight in adulthood. Decompositions reveal that only 20%-25% of this effect is attributable to advantaged families exhibiting better health behaviors, which implies that unobserved factors also play an important role. Since diseases associated with unhealthy weight place a major strain on public healthcare systems, our results have implications for the provision of treatment when resources are constrained.

Explaining the gaps in psychological distress and suicidal behaviours between non-Indigenous and Indigenous adults living off-reserve in Canada: a cross-sectional study

BACKGROUND

Indigenous people are disproportionately affected by mental health issues in Canada. We investigated factors underlying the difference in psychological distress and suicidal behaviours between non-Indigenous and Indigenous populations living off-reserve in Canada.

METHODS

We conducted a cross-sectional study using data from the 2012 Canadian Community Health Survey - Mental Health. Respondents were aged 18 years and older. We measured the variation in psychological distress (10-item Kessler Psychological Distress Scale scores, ranging from 10 [no distress] to 50 [severe distress]) and the prevalence of lifetime suicidal ideation and suicide plan between the Indigenous and non-Indigenous populations and explained these differences using the Blinder-Oaxaca approach.

RESULTS

The overall response rate for the survey was 68.9%, comprising 18 300 respondents (933 Indigenous and 17 367 non-Indigenous adults). We found lower mean psychological distress scores among non-Indigenous people than among Indigenous people (15.1 v. 16.1, p < 0.001) and a lower prevalence of lifetime suicidal ideation (9.2% v. 16.8%, p < 0.001) and plan (2.3% v. 6.8%, p < 0.001). We found that if socioeconomic status among Indigenous people were made to be similar to that of the non-Indigenous population, the differences in mean psychological distress scores and prevalence of lifetime suicidal ideation and suicide plan would have been reduced by 25.7% (women 20.8%, men 36.9%), 10.2% (women 11.2%, men 11.9%) and 5.8% (women 7.8%, men 8.1%), respectively.

INTERPRETATION

Socioeconomic factors account for a considerable proportion of the variation in mental health outcomes between non-Indigenous and Indigenous populations in Canada. Improving socioeconomic status among Indigenous people through plans like income equalization may reduce the gap in mental health outcomes between the 2 populations in Canada.

Association between household food insecurity and mortality in Canada: a population-based retrospective cohort study

BACKGROUND

Food insecurity affects 1 in 8 households in Canada, with serious health consequences. We investigated the association between household food insecurity and all-cause and cause-specific mortality.

METHODS

We assessed the food insecurity status of Canadian adults using the Canadian Community Health Survey 2005-2017 and identified premature deaths among the survey respondents using the Canadian Vital Statistics Database 2005-2017. Applying Cox survival analyses to the linked data sets, we compared adults' all-cause and cause-specific mortality hazard by their household food insecurity status.

RESULTS

Of the 510 010 adults sampled (3 390 500 person-years), 25 460 died prematurely by 2017. Death rates of food-secure adults and their counterparts experiencing marginal, moderate and severe food insecurity were 736, 752, 834 and 1124 per 100 000 person-years, respectively. The adjusted hazard ratios (HRs) of all-cause premature mortality for marginal, moderate and severe food insecurity were 1.10 (95% confidence interval [CI] 1.03-1.18), 1.11 (95% CI 1.05-1.18) and 1.37 (95% CI 1.27-1.47), respectively. Among adults who died prematurely, those experiencing severe food insecurity died on average 9 years earlier than their food-secure counterparts (age 59.5 v. 68.9 yr). Severe food insecurity was consistently associated with higher mortality across all causes of death except cancers; the association was particularly pronounced for infectious-parasitic diseases (adjusted HR 2.24, 95% CI 1.42-3.55), unintentional injuries (adjusted HR 2.69, 95% CI 2.04-3.56) and suicides (adjusted HR 2.21, 95% CI 1.50-3.24).

INTERPRETATION

Canadian adults from food-insecure households were more likely to die prematurely than their food-secure counterparts. Efforts to reduce premature mortality should consider food insecurity as a relevant social determinant.

Effect of firearms legislation on suicide and homicide in Canada from 1981 to 2016

Canada implemented a series of laws regulating firearms including background and psychological screening, licensing, and training in the years 1991, 1994, and 2001. The effects of this legislation on suicide and homicide rates were examined over the years 1981 to 2016. Models were constructed using difference-in-difference analysis of firearms and non firearms death rates from 1981 to 2016. In addition, negative binomial regression was used to test for an association between rates of suicide by Canadian Province and firearms prevalence, using licensing rates as a proxy for prevalence. No associated benefit from firearms legislation on aggregate rates of male suicide was found. In men aged 45 to 59 an associated shift from firearms suicide after 1991 and 1994 to an increase in hanging resulted in overall rate ratios of 0.994 (95%CI, 0.978,1.010) and 0.993 (95%CI, 0.980,1.005) respectively. In men 60 and older a similar effect was seen after 1991, 1994, and 2001, that resulted in rate ratios of 0.989 (95%CI, 0.971,1.008), 0.994 (95%CI, 0.979,1.010), and 1.010 (95%CI, 0.998,1.022) respectively. In females a similar effect was only seen after 1991, rate ratio 0.983 (95%CI, 0.956,1.010). No beneficial association was found between legislation and female or male homicide rates. There was no association found with firearm prevalence rates per province and provincial suicide rates, but an increased association with suicide rates was found with rates of low income, increased unemployment, and the percentage of aboriginals in the population. In conclusion, firearms legislation had no associated beneficial effect on overall suicide and homicide rates. Prevalence of firearms ownership was not associated with suicide rates. Multifaceted strategies to reduce mortality associated with firearms may be required such as steps to reduce youth gang membership and violence, community-based suicide prevention programs, and outreach to groups for which access to care may be a particular issue, such as Aboriginals.

Food insecurity in Nunavut following the introduction of Nutrition North Canada

BACKGROUND

Household food insecurity, a measure of income-related problems of food access, is a pressing public health problem in Canada's North, especially in Nunavut. We aimed to assess the impact of Nutrition North Canada, a food retail subsidy intended to improve food access and affordability in isolated communities, on household food insecurity in Nunavut.

METHODS

Using data from 3250 Nunavut households sampled in the annual components of the Canadian Community Health Survey (2007 to 2016), we conducted interrupted time series regression analyses to determine whether the introduction of Nutrition North Canada was associated with changes in the rates of self-reported food insecurity, according to a validated instrument. We used propensity score weighting to control for several sociodemographic characteristics associated with food insecurity.

RESULTS

Food insecurity affected 33.1% of households in 2010 (the year before the launch of Nutrition North Canada), 39.4% of households in 2011 (the year of the launch) and 46.6% of households in 2014 (the year after full implementation). After controlling for several covariates, we found the rate of food insecurity increased by 13.2 percentage points (95% confidence interval [CI] 1.7 to 24.7) after the full implementation of the subsidy program, and the increase in food insecurity first occurred in 2011 (9.6 percentage points, 95% CI 2.7 to 16.4), the year Nutrition North Canada was launched.

INTERPRETATION

Food insecurity was a pervasive problem in Nunavut before Nutrition North Canada, but it has become even more prevalent since the program was implemented. Given the important health consequences of food insecurity, more effective initiatives to address food insecurity in Canada's North are urgently needed.
