Comorbid substance use disorder, major depression, and associated disability in a nationally representative sample

BackgroundMajor depressive disorders (MDD) and substance use disorders (SUDs) are commonly linked to disability, but there is a lack of research on the risk of disability among individuals who have both SUDs and MD in the general population. This study aimed to investigate the associated risk of disability in people with comorbid SUDs- specifically cannabis use disorder, alcohol use disorder, other drug (except cannabis) use disorder, and a major depressive episode using a nationally representative sample. MethodsThe 2012 Canadian Community Health Survey- Mental Health (CCHS-MH) data were analyzed using multilevel logistic regression models. The survey included a nationally representative sample of Canadians aged 15 years and older (n = 25,113) residing in the ten Canadian provinces from January to December 2012. The diagnoses of major depressive episodes (MDE) and the SUDs were derived from the DSM-IV diagnostic criteria using a modified WHO-CIDI instrument, while disability was assessed using the World Health Organization Disability Assessment Score (WHODAS) 2.0. ResultsThe strongest predictor of disability was found to be comorbidity. Individuals diagnosed with both a SUD and MDE were 4 to 9 times more likely to experience disability, depending on the substance used, compared to those without either diagnosis. LimitationsThe study's cross-sectional design limits causal inferences. ConclusionsOur research discovered that individuals who have both SUD and MDE are at a significantly higher risk of experiencing disability. This highlights the importance of integrating mental health and addiction services to mitigate the risk of disability and improve overall treatment outcomes.

Chronic physical conditions and suicidal ideation: a population-level analysis of Canadian school-attending young adults

Background Students who identify with a chronic physical condition are a growing population and their conditions may be associated with poor mental well-being. Aim To compare suicidal ideation prevalence between Canadian school-attending young adults with and without a chronic physical condition. We hypothesized that students living with a chronic condition have a higher likelihood of experiencing suicidal ideation. Methods A cross-sectional study was conducted using a nationally representative sample of 2297 Canadian school-attending young adults (ages 15-29 years) from the 2012-13 Canadian Community Health Survey—Mental Health (CCHS-MH). Survey-weighted logistic regression and sensitivity analyses were performed to estimate the likelihood of experiencing suicidal ideation between students with and without a chronic physical condition. Results Approximately 14.3% (n = 329) students experienced suicidal ideation at some point. Students living with a physical chronic condition demonstrated 1.65 (95% CI: 1.14, 2.39) times higher odds of experiencing suicidal ideation, compared to students not living with a chronic physical condition. Conclusions Suicide prevention and health promotion are important considerations for campus health providers and administrators when planning services and accommodations for students living with chronic physical conditions.

Risk of suicide ideation in comorbid substance use disorder and major depression.

Suicidal behaviour is commonly associated with major depression (MD) and substance use disorders (SUDs). However, there is a paucity of research on risk for suicide ideation among individuals with comorbid SUDs and MD in the general population. This study investigated the associated risk of suicide ideation in comorbid SUDs-cannabis use disorder (CUD), alcohol use disorder (AUD), drug use disorder (DUD) with major depressive episode (MDE) in a nationally representative sample. Multilevel logistic regression models were used to analyze the 2012 Canadian Community Health Survey- Mental Health (CCHS-MH) data. This is a cross-sectional survey of nationally representative samples of Canadians (n = 25,113) aged 15 years and older residing in the ten Canadian provinces between January and December 2012. Diagnoses of MDE, AUD, DUD, and CUD were based on a modified WHO-CIDI, derived from DSM-IV diagnostic criteria. Comorbidity was found to be the strongest predictor of suicide ideation. Compared to those with no diagnosis of either a SUD or MDE, individuals with a comorbid diagnosis of AUD with MDE, CUD with MDE, or DUD with MDE were 9, 11 and 16 times more likely to have 12-month suicide ideation respectively. A diagnosis of MDE was a significant predictor of 12-month suicide ideation with about a 7-fold increased risk compared with individuals not diagnosed with either MDE or a SUD. Suicide is a preventable public health issue. Our study found a significantly increased risk of suicide ideation among persons who have comorbid SUD with MD. Effective integration of mental health and addictions services could mitigate the risk of suicide and contribute to better outcomes.

Negative Social Interactions at the Intersection of Gender, Race and Immigration Status in Canada

Abstract Negative social interactions (NSIs), defined as upsetting interpersonal encounters in daily life, are associated with adverse mental health conditions. Guided by an intersectional perspective, this study explored the impacts of gender, race and immigration status on the experiences of NSIs, using nationally representative data from the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH). The sample consisted of 21,932 participants across Canada. Gender-specific multivariable logistic regression models were used to estimate the effects of race, immigrant status and the interaction term on the likelihood to experience NSIs. Study results showed that women (32.3 per cent) reported significantly more NSIs than men (25.4 per cent). For men, being an immigrant was significantly associated with a lower likelihood of experiencing NSIs; race did not have a significant effect on NSIs. Furthermore, the results revealed that racialised Canadian-born women were more likely to report NSIs than racialised immigrant women, whilst immigration status had no effect among white women. This study suggests the distinct influences of intersecting identities of race, gender and immigration status and that social workers should incorporate an intersectional lens when exploring clients’ social relationships and environments.

Positive mental health in Canadian adults who have experienced childhood sexual abuse: exploring the role of social support

Purpose:Childhood sexual abuse (CSA) is predictive of poorer mental health, greater psychiatric disorder risk, and lower positive mental health (PMH) during adulthood, outcomes potentially moderated by social support. The current study aimed to explore whether Canadian adults who have experienced CSA differ from those who have not in terms of PMH and social support. Within the CSA sample, it was further investigated whether gender differences exist with respect to PMH and social support, and if particular social support subscales predict PMH.Method:Using data from the 2012 Canadian Community Health Survey – Mental Health (CCHS-MH), 1,328 adults between 20 and 64 years reporting CSA were profiled and compared in terms of sociodemographic and socioeconomic factors, using an age, sex, and frequency matched sample of non-CSA adults. Social Provisions Scale (SPS), and the Mental Health Continuum – Short Form (MHC-SF) means were subsequently compared between the CSA and non-CSA samples, and Hierarchical regressions were conducted for CSA males and females separately to examine whether SPS subscales predicted PMH after controlling for age and income.Results:Canadian adults reporting CSA had significantly lower PMH and social support (overall and for particular subscales). For adult CSA females, guidance, social integration, and reassurance of worth predicted higher PMH, while attachment and reassurance of worth predicted higher PMH scores for CSA males.Conclusion:Adults who have experienced CSA are at risk for lower PMH and social support. Gender differences are also evident in social support subtypes that predict PMH which have important clinical implications.

Religion/Spirituality, Mental Health, and the Lifespan: Findings from a Representative Sample of Canadian Adults.

Theories of adult development and aging suggest that older adults turn towards religion and spirituality (R/S) to increase meaning and purpose in life, and to assist in coping with adverse experience. We sought to examine the relationship between R/S and positive mental health and mental illness (i.e., psychological distress) in adulthood, and to determine the potential moderating role of age. Data from the 2012 Canadian Community Health Survey - Mental Health (CCHS-MH), a national population health study, were used. A multivariable linear regression model revealed a significant R/S by age interaction for positive mental health (p = 0.001). Although R/S was associated with positive mental health among all participants, there was a stronger relationship between R/S and positive mental health for older adults. No statistically significant relationship between R/S and psychological distress was observed. Findings highlight the importance of R/S to positive mental health across the adult lifespan. The differential relationships among R/S, positive mental health, and mental illness underscore the utility of using the dual-continua of mental health and mental illness in order to understand their respective determinants.

Attention-Deficit/Hyperactivity Disorder and Alcohol and Other Substance Use Disorders in Young Adulthood: Findings from a Canadian Nationally Representative Survey.

(a) To document the prevalence and odds of (i) alcohol use disorders, (ii) cannabis use disorders, (iii) other drug use disorders and (iv) any substance use disorder (SUD), among young adults with and without ADHD, and (b) to investigate the degree to which the association between ADHD and SUDs is attenuated by socio-demographics, early adversities and mental health. Secondary analysis of the nationally representative Canadian Community Health Survey-Mental Health (CCHS-MH). The sample included 6872 respondents aged 20-39, of whom 270 had ADHD. The survey response rate was 68.9%. Substance Use Disorder: World Health Organization's Composite International Diagnostic Interview criteria, SUDs, were derived from lifetime algorithms for alcohol, cannabis and other substance abuse or dependence. ADHD was based on self-report of a health professional's diagnosis. One in three young adults with ADHD had a lifetime alcohol use disorder (36%) compared to 19% of those without ADHD (P< 0.001). After adjusting for all control variables, those with ADHD had higher odds of developing alcohol use disorders (OR = 1.38, 95% CI: 1.05, 1.81), cannabis use disorders (OR = 1.46, 95% CI: 1.06, 2.00), other drug use disorders (OR = 2.07, 95% CI: 1.46, 2.95) and any SUD (OR = 1.69, 95% CI: 1.28, 2.23). History of depression and anxiety led to the largest attenuation of the ADHD-SUD relationship, followed by childhood adversities and socioeconomic status. Young adults with ADHD have a high prevalence of alcohol and other SUDs. Targeted outreach and interventions for this extremely vulnerable population are warranted.

Flourishing Despite Migraines: A Nationally Representative Portrait of Resilience and Mental Health among Canadians

Objective 1) To examine the relationship between migraine status and complete mental health (CMH) among a nationally representative sample of Canadians; 2) To identify significant correlates of CMH among those with migraine. Methods Secondary analysis of the nationally representative Canadian Community Health Survey – Mental Health (CCHS-MH) (N=21,108). Bivariate analyses and a series of logistic regression models were performed to identify the association between migraine status and CMH. Significant correlates of CMH were identified in the sample of those with migraine (N=2,186). Results Individuals without a history of migraine had 72% higher odds of being in CMH (OR=1.72; 95% CI=1.57, 1.89) when compared with those with a history of migraine. After accounting for physical health and mental health problems, the relationship between migraine status and CMH was reduced to non-significance, with both groups having an approximately equal likelihood of achieving CMH (OR=1.03; 05% CI=(0.92, 1.15). Among those with migraine, factors that were strongly associated with CMH were a lack of a history of depression, having a confidant, and having an income of $80,000 or more. Conclusion Clinicians and health care providers should also address co-occurring physical and mental health issues to support the overall well-being of migraineurs.

The Dark Side of ADHD: Factors Associated With Suicide Attempts Among Those With ADHD in a National Representative Canadian Sample

Aim This study investigated the prevalence and odds of suicide attempts among adults with attention deficit hyperactivity disorder (ADHD) compared to those without and identified factors associated with suicide attempts among adults with ADHD. Methods Secondary analysis of the nationally representative Canadian Community Health Survey–Mental Health (CCHS-MH) (n = 21,744 adults, of whom 529 had ADHD). Respondents were asked whether they received an ADHD diagnosis from a health care professional. Lifetime suicide attempt was based on self-report. Results Adults with ADHD were much more likely to have attempted suicide than those without (14.0% vs. 2.7%). One in four women with ADHD have attempted suicide. Sixty percent of the association between ADHD and attempted suicide was attenuated when lifetime history of depression and anxiety disorders were taken into account. Female gender, lower education attainment, substance abuse, lifetime history of depression, and childhood exposure to chronic parental domestic violence were found to be independent correlates of lifetime suicide attempts among those with ADHD. Conclusion These findings can inform targeted screening and outreach to the most vulnerable adults with ADHD.

Negative Social Experiences Mediate the Relationship between Sexual Orientation and Mental Health

ABSTRACT The lesbian-gay-bisexual (LGB) population experiences a higher rate of psychopathology than the non-LGB population. Minority stress theory (MST) suggests that this pattern of findings is due to the increased negativity that LGB individuals face; however, MST is often employed as a post-hoc explanation for health inequalities as opposed to an a priori approach that explicitly tests this idea and has not been examined in the context of Canadian sexual minorities. Using the 2012 Canadian Community Health Survey—Mental Health (CCHS-MH), we tested the MST on a sample 22,495 Canadians (n = 21,995 non-LGB; n = 500 LGB). Results indicated that respondents’ scores on the Negative Social Interactions scale (NSI) partially mediated the relationship between LGB status and both depression and satisfaction with life. The findings suggest that a substantial component of the relationship between sexual orientation and mental health is influenced by deleterious social exchanges.

Childhood maltreatment as a risk factor for cancer: findings from a population-based survey of Canadian adults

BackgroundChildhood maltreatment (CM) is an established risk factor for various mental and substance use disorders. This study adds to existing evidence that CM may also be a risk factor for cancer.MethodsBased on data from a sample of 9783 men and 12,132 women from the 2012 Canadian Community Health Survey - Mental Health (CCHS-MH), this analysis explores mediated associations between cancer in adulthood and different levels of exposure to three types of CM—childhood physical abuse (CPA), childhood sexual abuse (CSA), and childhood exposure to intimate partner violence (CEIPV). “Cancer” was defined as an affirmative response to either of these questions: “Do you have cancer?” or “Have you ever been diagnosed with cancer?” The potential mediators were: smoking, depression, alcohol abuse/dependence, life stress, obesity, and physical activity.ResultsFor women, but not men, having experienced CM was significantly associated with a cancer diagnosis in adulthood, even when effects due to age and socio-demographic characteristics were controlled. Smoking, life stress, depression, and alcohol abuse/dependence reduced the strength of the association between CM and cancer in women. However, most associations remained statistically significant when controlling for effects due to these behavioural and other mediators. Evidence indicated a “dose-response” relationship, in that the likelihood of reporting cancer increased with the number of abuse types (CPA, CSA, CEIPV) reported, and with the severity of CPA.ConclusionsThe analyses suggest an association between CM and cancer in women, even when the effects of known risk factors were taken into account. The association was graded, becoming stronger as CM exposure increased. Implications for the provision of cancer screening and other health care services to women with histories of CM to reduce health disparities are discussed.

Concordance between health administrative data and survey-derived diagnoses for mood and anxiety disorders.

To assess whether estimates of survey structured interview diagnoses of mood and anxiety disorders were concordant with diagnoses of these disorders obtained from health administrative data. All Ontario respondents to the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH) were linked to health administrative databases at ICES (formerly known as the Institute for Clinical Evaluative Sciences). Survey structured interview diagnoses were compared with health administrative data diagnoses obtained using a standardized algorithm. We used modified Poisson regression analyses to assess whether socio-demographic factors were associated with concordance between the two measures. Of the 4157 Ontarians included in our sample, 20.4% had either a structured interview diagnosis (13.9%) or health administrative diagnosis (10.4%) of a mood or anxiety disorder. There was high discordance between measures, with only 19.4% agreement. Migrant status, age, employment, and income were associated with discordance between measures. Our findings indicate that previous estimates of the 12-month prevalence of mood and anxiety disorders in Ontario may be underestimating the true prevalence, and that population-based surveys and health administrative data may be capturing different groups of people. Understanding the limitations of data commonly used in epidemiologic studies is a key foundation for improving population-based estimates of mental disorders.

Aboriginal peoples in complete mental health: A nationally-representative Canadian portrait of resilience and flourishing.

This study aimed to document the prevalence and factors associated with complete mental health (CMH) among Aboriginal peoples living in Canada. CMH is comprised of three parts: 1) the absence of major depressive episode, anxiety disorders, bipolar disorder, serious suicidal thoughts, and substance dependence in the past year as measured by the World Health Organization (WHO) versions of the Composite International Diagnostic Interview (WHO-CIDI), 2) happiness and/or satisfaction with life in the past month, and 3) psychological and social well-being. The method involved secondary analysis of Statistics Canada's 2012 Canadian Community Health Survey-Mental Health (CCHS-MH). Responses from Aboriginal peoples living in Canada off-reserve (n = 965) were examined to determine what percentage were in CMH and what characteristics are associated with being in CMH. Data analysis involved both bivariate and multivariate analytic techniques to examine factors associated with CMH among Aboriginal peoples. Overall, two-thirds of Aboriginal peoples (67.9%) living in Canada were in CMH. Those with a post-secondary degree, who had a confidant, and those who were free of disabling chronic pain were more likely to be in CMH. Additionally, the odds of CMH were higher among those without a history of suicidal ideation, major depression, alcohol dependence, drug dependence, anxiety disorder, or difficulty sleeping. Findings from this study provide indications of substantial resiliency among Aboriginal peoples in Canada.

Suicide Attempts among Those with Migraine: Findings from a Nationally Representative Canadian Study

The objectives of this study were to identify the gender-specific prevalence of suicide attempts among those with migraine and to examine what factors are associated with suicide attempts among migraineurs. This study was a nationally representative analysis of the 2012 Canadian Community Health Survey - Mental Health (CCHS-MH) with 21,744 respondents, of whom 2,223 had migraine. Bivariate and logistic regression analyses were conducted. Those with migraine had a much higher prevalence of ever attempting suicide than those without migraine (men: 7.5% vs 1.9%; women; 9.3% vs 2.7%, p < .001). Among migraineurs, the odds of suicide attempts were higher among poorer respondents, those in chronic pain and those with a history of childhood adversities, substance dependence and/or mental illness. Targeted outreach is needed to reduce suicidality in this vulnerable population.

Traffic Violations among Young People with Attention-Deficit Hyperactivity Disorder.

Evidence whether individuals with attention-deficit hyperactivity disorder (ADHD) are at increased risk for traffic violations/collisions is mixed. This study investigated the association between ADHD and traffic violations among youth and young adults; examined whether this association differed by age, sex, or comorbid mental or physical problems; and modelled factors associated with traffic violations among individuals with ADHD. Data come from the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH), a cross-sectional epidemiological study. The sample was restricted to youth and young adults aged 15 to 39 years and categorized into 3 groups: 15 to 19 years (n = 1886), 20 to 29 years (n = 3679), and 30 to 39 years (n = 3659). Lifetime ADHD and past-year contact with police for traffic violations were self-reported. Logistic regression models quantified the association between ADHD and traffic violations, stratified by age. Interactions were included to examine moderating effects. No evidence suggested an association between ADHD and past-year traffic violations (odds ratio [OR], 1.07; 95% confidence interval (CI), 0.64 to 1.79), age-specific estimates did not differ across age groups (P = 0.696), and no factors moderated the association. Three factors were found to increase odds for past-year traffic violations among individuals with ADHD: aged 20 to 29 years (OR, 3.84; 95% CI, 1.47 to 10.06), male sex (OR, 3.48; 95% CI, 1.39 to 8.59), and white ethnicity (OR, 5.62; 95% CI, 1.24 to 25.51). Individuals with ADHD are not an at-risk group for traffic violations but instead share similar risk factors with individuals in the general population without ADHD-information useful for health professionals. Replication studies are needed to examine the robustness of these findings.

Effects of Suicidal Ideation on Unmet Mental Health Needs Among Young Adults in Canada

Although there has been an increase in public health campaigns and initiatives aimed at preventing suicidal behaviors, suicide rates in Canada appear to be increasing particularly among young adults. Yet, few studies in Canada have examined the effect of suicidal ideation on unmet mental health needs among young adults. The objective of this study is to examine the association between suicidal ideation and unmet mental health needs, over and above predisposing, enabling, and need factors. This study uses data on 3393 young adults aged 20–29 years from the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH). Binary logistic regression analysis was conducted with unmet mental health needs as the outcome variable and suicidal ideation as the main explanatory variable. Of the 3393 respondents, 8.8% had unmet mental health needs and 16.5% had suicidal ideation. In the multivariate logistic regression model, respondents who experienced suicidal ideation had 2.55 times higher odds of having unmet mental health needs. Respondents were also more likely to have unmet mental health needs if they are female, experienced childhood adversity, or were diagnosed with mental health disorders or cannabis abuse or dependence. Each additional unit increase in social support decreased the odds of unmet mental health needs by 11%. Community peer support programs for young adults may be beneficial in enhancing access to mental health particularly for at-risk individuals.

Does mandatory reporting legislation increase contact with child protection? \u2013 a legal doctrinal review and an analytical examination

BackgroundWithin Canadian provinces over the past half-century, legislation has been enacted to increase child protection organization (CPO) involvement in situations of child maltreatment (CM). This study had two objectives: 1) to document enactment dates of legislation for mandatory reporting of CM; 2) to examine reported CPO involvement among people reporting a CM history in relation to the timing of these legislative changes.MethodsThe history of mandatory reporting of CM was compiled using secondary sources and doctrinal legal review of provincial legislation. The 2012 Canadian Community Health Survey - Mental Health (CCHS-MH) with n = 18,561 was analyzed using birth cohorts to assess associations between the timing of legislation enactment and contact with CPO.ResultsAll Canadian provinces currently have mandatory reporting of physical and sexual abuse; 8 out of 10 provinces have mandatory reporting for children’s exposure to intimate partner violence. Increases in reporting CM to CPOs paralleled these laws’ enactment, particularly for severe and frequent CM.ConclusionsThese findings show that mandatory reporting laws increase reporting contact with CPO, particularly for severe and frequent CM. Whether they have had the intended effect of improving children’s lives remains an important, unanswered question.

An Epidemiological Study of Substance Use Disorders Among Emerging and Young Adults

We investigated the prevalence of substance use disorders (SUDs) among emerging adults and quantified the extent to which emerging adults, compared with young adults, have increased odds for SUDs. Data were from the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH). Respondents were 15 to 39 y of age ( n = 9228) and were categorized as: early emerging adults (15 to 22 y); late emerging adults (23 to 29 y); and, young adults (30 to 39 y). SUDs [alcohol or drug abuse/dependence (AAD or DAD)] were measured using the WHO Composite International Diagnostic Interview 3.0. The prevalence of SUDs was compared across age groups, and odds ratios (OR) and 95% confidence intervals (CI) were computed from logistic regression models adjusting for sociodemographic and health covariates. Analyses were weighted to maintain representativeness to the Canadian population. The prevalence of AAD was 8.0%, 6.6%, and 2.7% for early emerging adults, late emerging adults, and young adults, respectively. For DAD, the prevalence was 6.4%, 3.6%, and 1.3%. After covariate adjustment, early and late emerging adults had greater odds of reporting AAD (OR = 3.2, 95% CI = 2.2 to 4.9 and OR = 2.4, 95% CI = 1.6 to 3.4, respectively) or DAD (OR = 4.2, 95% CI = 2.5 to 7.0 and OR = 2.5, 95% CI = 1.6 to 4.1, respectively) compared with young adults. Differences between early and late emerging adults were not significant. Emerging adults are at increased odds for SUDs. Lack of differences between early and late emerging adults provide evidence of the extension of emerging adulthood into the late 20s. Findings have implications for the provision of screening and treatment of SUDs during this developmental period.

Chronic disruptive pain in emerging adults with and without chronic health conditions and the moderating role of psychiatric disorders: Evidence from a population-based cross-sectional survey in Canada

Background and aimsThere has been a growth in the proportion of emerging adults vulnerable to pain-related sequelae of chronic health conditions (CHCs). Given the paucity of research during this important developmental period, this study investigated the association between CHCs and chronic disruptive pain among emerging adults and the extent to which psychiatric disorders moderate this association. MethodsData come from the 2012 Canadian Community Health Survey – Mental Health (CCHS-MH). This cross-sectional survey included 5987 participants that were 15–30 years of age and self-reported their CHCs (n=2460, 41%) and the extent to which pain impacted daily functioning using items from the Health Utilities Index Mark 3 (HUI 3). Group comparisons between respondents with CHCs and healthy controls were made using chi-square tests. Odds ratios (OR) and 95% confidence intervals (CI) were computed from ordinal logistic regression models adjusting for sociodemographic covariates. Product-term interactions between CHCs and psychiatric disorders were included in the models to explore moderating effects. All analyses were weighted to maintain representativeness of the study sample to the Canadian population. ResultsThe mean age of participants was 23.5 (SE 0.1) years and 48% were female. Compared to healthy controls, a greater proportion of participants with CHCs reported having chronic pain (20.3% vs. 4.5%, p<0.001). Among those with chronic pain, respondents with CHCs reported a greater number of activities prevented because of chronic disruptive pain (χ2=222.28, p<0.001). Similarly, in logistic regression models, participants with CHCs had greater odds of reporting chronic disruptive pain (OR=4.94, 95% CI=4.08–5.99). Alcohol (β=−0.66; p=0.025) and drug abuse/dependence disorders (β=−1.24; p=0.012) were found to moderate the association between CHCs and chronic disruptive pain. Specifically, the probability of chronic disruptive pain was higher for emerging adults without CHCs and with alcohol or drug disorders; however, among participants with CHCs, probability was higher for those without these disorders. ConclusionsThere is a robust association between CHCs and chronic disruptive pain. The moderating effects suggest that alcohol or drug disorders are especially harmful for emerging adults without CHCs and contribute to higher levels of chronic disruptive pain; however, among those with CHCs, alcohol and illicit drugs may be used as a numbing agent to blunt chronic disruptive pain. ImplicationsFindings from this study have implications for the integration and coordination of services to design strategies aimed at managing chronic disruptive pain and preventing pain-related disabilities later in life. Within the health system, healthcare providers should engage in dialogues about mental health and substance use regularly with emerging adults, be proactive in screening for psychiatric disorders, and continue to monitor the impact of pain on daily functioning. Given the age range of emerging adults, there is tremendous opportunity for clinicians to work cooperatively with colleagues in the education system to support emerging adults with and without CHCs. Overall, clinicians, researchers, educators, and those in social services should continue to be mindful of the complex interrelationships between physical and mental health and chronic disruptive pain and work cooperatively to optimize health outcomes and prevent pain-related disabilities among emerging adults.

Is child sexual abuse declining in Canada? Results from nationally representative retrospective surveys.

Numerous data sources suggest a decline in child sexual abuse (CSA) in the United States since the early 1990s. Some evidence also indicates that an earlier period of higher CSA incidence began following World War II. This study examines prevalence estimates of sexual abuse reported retrospectively as having occurred in childhood (ChSA) in two nationally representative surveys of the Canadian population. Data are from 13 931 respondents aged 18 to 76 years from the 2004/2005 Canadian Gender, Alcohol, and Culture: An International Study (GENACIS), and from 22 169 household residents aged 18 years or older who participated in the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH). We present inter- and intrasurvey comparisons of ChSA prevalence specific to sex and age groups. Findings from both surveys suggest a decline in CSA since 1993, consistent with declines observed in the United States. Results also suggest that 1946 to 1992 was a period of higher risk of CSA, relative to the period before 1946. The evidence was more robust for women. Evidence of a decline in CSA in Canada since the early 1990s is encouraging, given the long-term debilitating effects with which it is associated. Continued monitoring is critical. The long-term negative effects associated with CSA underscore the importance of continuing to move from lower risk to zero risk.
