Objectives: To present the 12-month prevalence and correlates of suicidal ideation and attempts in a sample of youth in Ontario., Methods: Data come from the 2014 Ontario Child Health Study, a provincially representative survey of families with children in Ontario. Youth aged 14 to 17 y ( n = 2,396) completed a computer-assisted, self-administered questionnaire in their home to assess the occurrence of suicidal ideation, suicidal attempts, and associated correlates, including non-suicidal self-injury, mental disorders, substance use, peer victimization and exposure to child maltreatment. Socio-demographic information was collected from the parent. Logistic regression models were used to identify correlates that distinguished between youth reporting: 1) no suicidal ideation or attempts, 2) suicidal ideation but no attempts, and 3) suicidal ideation and attempts., Results: The 12-month prevalence of suicidal ideation and attempts was 8.1% and 4.3%, respectively. All clinical and behavioural correlates were significantly higher among youth reporting suicidal ideation or attempts, as compared with non-suicidal youth. In adjusted models, depression and non-suicidal self-injury were each independently associated with elevated odds of suicidal ideation (OR = 4.84 and 4.19, respectively) and suicidal attempt (OR = 7.84 and 22.72, respectively). Among youth who reported suicidal ideation, the only variable that differentiated youth who attempted suicide v. those who did not, in adjusted models, was non-suicidal self-injury (OR = 3.89)., Conclusions: Suicidal ideation and attempts are common among youth in Ontario, often co-occurring with mental disorders and high-risk behaviours. These findings underscore the need for effective prevention and intervention strategies, particularly for youth depression and non-suicidal self-injury.

Objective: The aims of this study were to estimate the: (1) 12-mo prevalence of suicidal thoughts, plans, and attempts in a population sample of adolescents and young adults with and without chronic illness; (2) associations among chronic illness and suicidal thoughts and behaviour (STB); and, (3) moderating roles of mood and substance use disorder on this association., Method: Individuals were aged 15 to 30 y ( n = 5,248) from the Canadian Community Health Survey-Mental Health. Twelve-month STB and psychiatric disorder were measured using the World Health Organization Composite International Diagnostic Interview 3.0. Multinomial logistic regression examined associations between chronic illness and STB, adjusting for relevant sociodemographic and health characteristics. Product term interactions among chronic illness, mood, and substance use disorders were included in the regression models to examine potential moderating effects., Results: Prevalence of suicidal thoughts, plans, and attempts was higher in individuals with chronic illness ( P < 0.01 for all). After adjustment, chronic illness increased the odds for suicidal thoughts [OR = 1.28 (1.01 to 1.64)], plans [OR = 2.34 (1.22 to 4.39)], and attempts [OR = 4.63 (1.52 to 14.34)]. In the presence v. absence of a mood disorder, the odds for suicidal thoughts were higher among individuals with chronic illness [OR = 1.89 (1.06 to 5.28)]., Conclusions: Suicidal thoughts and behaviours are common among adolescents and young adults with chronic illness, particularly among those with comorbid mood disorders. Health professionals should routinely ask about STB during assessments of their adolescent and young adult patients.

Objective: Given the public health importance of suicide-related behaviors and the corresponding gap in the performance measurement literature, we sought to identify key candidate process indicators (quality of care measures) and structural measures (organizational resources and attributes) important for emergency department (ED) management of pediatric suicide-related behaviors., Methods: We reviewed nationally endorsed guidelines and published research to establish an inventory of measures. Next, we surveyed expert pediatric ED clinicians to assess the level of agreement on the relevance (to patient care) and variability (across hospitals) of 42 candidate process indicators and whether 10 hospital and regional structural measures might impact these processes., Results: Twenty-three clinicians from 14 pediatric tertiary-care hospitals responded (93% of hospitals contacted). Candidate process indicators identified as both most relevant to patient care (≥87% agreed or strongly agreed) and most variable across hospitals (≥78% agreed or strongly agreed) were wait time for medical assessment; referral to crisis intervention worker/program; mental health, psychosocial, or risk assessment requested; any inpatient admission; psychiatric inpatient admission; postdischarge treatment plan; wait time for first follow-up appointment; follow-up obtained; and type of follow-up obtained. Key hospital and regional structural measures (≥87% agreed or strongly agreed) were specialist staffing and type of specialist staffing in or available to the ED; regional policies, protocols, or procedures; and inpatient psychiatric services., Conclusions: This study highlighted candidate performance measures for the ED management of pediatric suicide-related behaviors. The 9 candidate process indicators (covering triage, assessment, admission, discharge, and follow-up) and 4 hospital and regional structural measures merit further development.

Objectives: To describe individuals who reported suicidal ideation but neither met the criteria for major depression (MD) nor were in contact with mental health services in the previous year.Method: Data were drawn from the Canadian Community Health Survey: Mental Health and Well-Being (CCHS 1.2). Conducted in 2002, the CCHS 1.2 was a cross-sectional population-based survey of 36 984 Canadian household residents aged 15 years or more. First, we described the individuals who reported suicidal ideation, were without MD, and were not in contact with mental health services (n = 584) as well as their nonsuicidal counterparts (n = 31 382) based on various demographic and health status variables. Second, to analyse whether these same variables are associated with mental health service contact(s) among suicidal individuals without MD, we compared those who were in contact with mental health services (n = 209) to those who were not (n = 584).Results: Almost one-half (47.9%) of the suicidal ideators were without both MD and a mental health service contact in the previous year. Individuals in this group were younger and exhibited greater morbidity than their nonsuicidal counterparts (without MD or mental health service contact) but did not differ by sex. Although male and female respondents were equally represented among the suicidal ideators without MD, male respondents were less likely to contact mental health services. Such contact was more likely among female respondents and individuals with an anxiety disorder.Conclusions: These findings underscore the need for further research evaluating early intervention programs that succeed in capturing suicidal youths, particularly male youths.

Objective: To determine whether, and to what extent, those who reported suicidal ideation and (or) attempts in the previous year, without meeting the criteria for major depressive episode (MDE), might still have experienced subthreshold depression.Method: Data from the Canadian Community Health Survey: Mental Health and Well-Being (CCHS 1.2) were examined to estimate and compare the prevalence of depressed mood, a core symptom of MDE and subthreshold depression, within the previous month for the following 4 population groups: MDE within the previous month [D(1 month)], MDE within the previous year but not the previous month [D(1 year)], suicidality without MDE within the previous year (D-S+), and no MDE or suicidality within the previous year (D-S-).Results: As expected, the D(1 month) group showed the highest prevalence of depressed mood in the previous month. However, the D-S+ group had a significantly higher prevalence of depressed mood than the D-S- group and only a slightly lower level than that of the D(1 year) group.Conclusions: A fraction of those who reported suicidality in the previous year met the criteria for MDE during that time; however, subthreshold depression might be common in the suicidal population. Future epidemiologic research in the areas of suicidality and depression will benefit from a comprehensive assessment of subthreshold depression. [ABSTRACT FROM AUTHOR]
