Introduction: 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. Methods: 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. Results: 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. Conclusion: 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. [ABSTRACT FROM AUTHOR]

Introduction: Young mothers' families are at increased risk of child maltreatment and other poor health and social outcomes. Methods: Chi-square analyses of pooled child welfare services data from the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS--2003; CIS--2008) were used to compare 284 teen mothers (18 years or younger) and 800 young mothers (19-21 years) and their families with 5752 families where the mother was 22 years or older. Results: Twenty-six percent of young mothers were 18 years or younger. Most (68% of teen-mother families and 57% of families with a young adult mother) received social assistance as their main source of income compared with 36% of families with a mother aged 22 years or older. Teen and young adult mothers were more likely than those aged 22 or older to have childhood histories of out-of-home care (31% and 23% vs. 10%) and were more likely to have risk factors such as alcohol abuse (25% and 23% vs. 18%) and few social supports (46% and 41% vs. 37%). Secondary caregivers in families with young mothers also had more risk factors. Teen and young adult mother families were more likely to have their child placed out-of-home during the investigation (29% and 27% vs. 17%). All were equally likely to be victims of domestic violence and to have mental health issues. Conclusion: Within this sample of high-risk families, young mothers' families were more at risk than comparison families. Mothers' youth may be a useful criterion to identify families for targeted interventions. [ABSTRACT FROM AUTHOR]

Introduction: Our study examines the frequency of joint investigations by child protection workers and the police in sexual abuse investigations compared to other maltreatment types and the association of child-, caregiver-, maltreatment- and investigation-related characteristics in joint investigations, focussing specifically on investigations involving sexual abuse. Methods: We analyzed data from the Canadian Incidence Study of Reported Child Abuse and Neglect--2008 using logistic regression. Results: The data suggest that sexual abuse (55%), and then physical abuse, neglect and emotional maltreatment, are most often co-investigated. Substantiation of maltreatment, severity of maltreatment, placement in out-of-home care, child welfare court involvement and referral of a family member to specialized services was more likely when the police were involved in an investigation. Conclusion: This study adds to the limited information on correlates of joint child protection agency and police investigations. Further research is needed to determine the effectiveness of these joint investigations. [ABSTRACT FROM AUTHOR]

Introduction: The objective of this analysis is to identify, assess the quality and summarize the findings of peer-reviewed articles that used data from the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS) published since November 2011 and data from provincial oversamples of the CIS as well as to illustrate evolving uses of these datasets. Methods: Articles were identified from the Public Health Agency of Canada's data request records tracking access to CIS data and publications produced from that data. At least two raters independently reviewed and appraised the quality of each article. Results: A total of 32 articles were included. Common strengths of articles included clearly stated research aims, appropriate control variables and analyses, sufficient sample sizes, appropriate conclusions and relevance to practice or policy. Common problem areas of articles included unclear definitions for variables and inclusion criteria of cases. Articles frequently measured the associations between maltreatment, child, caregiver, household and agency/referral characteristics and investigative outcomes such as opening cases for ongoing services and placement. Conclusion: Articles using CIS data were rated positively on most quality indicators. Researchers have recently focussed on inadequately studied categories of maltreatment (exposure to intimate partner violence [IPV]), neglect and emotional maltreatment) and examined factors specific to First Nations children. Data from the CIS oversamples have been underutilized. The use of multivariate analysis techniques has increased. [ABSTRACT FROM AUTHOR]

Introduction: The purpose of this study was to analyze how child maltreatment surveillance data from the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS) is used by senior child welfare decision makers. Methods: This triangulation mixed-methods study included quantitative and qualitative methods to facilitate an in-depth exploration from multiple perspectives. We interviewed Ontario child welfare decision makers to measure utilization of the CIS in policy development. Results: The majority of respondents were aware of the CIS data. Decision makers reported using these data to determine resource allocation, understand reported maltreatment trends and validate findings at their own agencies. Urban agencies used the data more than did rural agencies. Conclusion: This study is the first to triangulate data to understand and improve utilization of child maltreatment surveillance data. The study participants indicated considerable appreciation of the data and also provided ideas for improvements across the surveillance cycle. [ABSTRACT FROM AUTHOR]

Missing data is a common problem in epidemiological studies. The problems associated with analysing data with missing information have received little attention in child maltreatment research. The Canadian Incidence Study of Reported Child Abuse and Neglect was analysed to identify missing information and investigate patterns of its occurrence. It was clear that the data were not missing at random. Discussions for improvement of data collection tools and implications for mental health promotion are discussed. [ABSTRACT FROM AUTHOR]

Introduction: As a part of the public health approach to child welfare, data about children placed in out-of-home care are needed to assess population trends, understand drivers of social and health inequities, and examine outcomes for children and families. We analyzed administrative data from Canada to describe the population of children in out-of-home care, and estimate and compare rates of out-of-home care by province/territory, year, sex/gender, age group and placement type., Methods: We conducted a cross-sectional analysis of point-in-time data from all provinces and territories for the period 2013/2014 to 2021/2022. We used frequencies and percentages to describe the population of children (and youth up to age 21 years) in out-of-home care and estimated overall and stratified rates and rate ratios., Results: An estimated 61 104 children in Canada were in out-of-home care on 31 March 2022. The national rate of out-of-home care was 8.24 children per 1000 population. Rate variations by province/territory were substantial and changed over time. Rates were highest among males and children aged 1 to 3 and 16 to 17 years. Foster homes were the most common type of placement, although kinship homes accounted for an increasing share., Conclusion: This analysis demonstrated that administrative data can be used to generate national indicators about children involved in the child welfare system. These data can be used for tracking progress towards health and social equity for children and youth in Canada., Competing Interests: The authors have no conflicts of interest to declare.

Objectives: Depression is associated with problems in functioning in many aspects of life, including parenting. COVID-19 has increased risk factors for depression. We investigated the prevalence of depression among parents during the pandemic and the association with dysfunctional parenting., Design: Canadian nationwide cross-sectional study., Setting and Participants: The 2020 and 2021 Surveys on COVID-19 and Mental Health (SCMH) and the Canadian Community Health Survey (CCHS) (2015‒2019). Responding sample sizes for parents were 3121 for the 2020-SCMH; 1574 for the 2021-SCMH and 6076 for the CCHS., Primary Outcome Measures: All three surveys collected information on symptoms of major depressive disorder (MDD). The SCMH measured harsh parenting., Results: Based on data from the 2021-SCMH collected during wave 3 of COVID-19, 14.4% of fathers and 21.2% of mothers screened positive for MDD. These prevalence estimates were similar to those from the 2020-SCMH during wave 2, but at least two times higher than pre-COVID-19 estimates from the CCHS. Multivariate analyses revealed a linear association between MDD and harsh parenting. COVID-19-related stressors were associated with harsh parenting. Among mothers, feeling lonely or isolated because of COVID-19 was a risk factor for harsh parenting; among fathers, being a front-line worker was a risk factor. Meditation was a protective factor for mothers., Conclusions: After years of stability, the prevalence of MDD increased substantially among Canadian parents during the pandemic. Ongoing monitoring is vital to determine if elevated levels of depression persist because chronic depression increases the likelihood of negative child outcomes. Programmes aimed at addressing depression and bolstering parenting skills are needed as families continue to face stressors associated with COVID-19., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Using data from the 2020 and 2021 cycles of the Survey on COVID-19 and Mental Health,we examined suicidal ideation among adults in Canada aged 18 to 34 years. The prevalence of suicidal ideation among adults aged 18 to 34 years was 4.2% in fall 2020 and 8.0% in spring 2021. The subgroup of adults aged 18 to 24 years had the highest prevalence of suicidal ideation, 10.7%, in spring 2021. Prevalence varied by sociodemographic characteristics and tended to be higher among people living in materially deprived areas. Suicidal ideation was strongly associated with pandemic-related stressors respondents experienced., Competing Interests: The authors have no conflicts of interest.

Introduction: Recent evidence has suggested an increase in suicidal ideation during the COVID-19 pandemic. Our objectives were to estimate the likelihood of suicidal ideation among adults in Canada who experienced pandemic-related impacts and to determine if this likelihood changed during the pandemic., Methods: We analyzed pooled data for 18 936 adults 18 years or older who responded to two cycles of the Survey on COVID-19 and Mental Health collected from 11 September to 4 December 2020 and from 1 February to 7 May 2021. We estimated the prevalence of suicidal ideation since the pandemic began and conducted logistic regression to evaluate the likelihood of suicidal ideation by adults who experienced pandemic-related impacts, and by factors related to social risk, mental health status, positive mental health indicators and coping strategies., Results: Adults who had adverse pandemic-related experiences were significantly more likely to experience suicidal ideation; a dose-response relationship was evident. People who increased their alcohol or cannabis use, expressed concerns about violence in their home or who had moderate to severe symptoms of depression, anxiety or posttraumatic stress disorder also had significantly higher risk of suicidal ideation. The risk was significantly lower among people who reported high self-rated mental health, community belonging or life satisfaction, who exercised for their mental and/or physical health or who pursued hobbies., Conclusion: The COVID-19 pandemic has influenced suicidal ideation in Canada. Our study provides evidence for targeted public health interventions related to suicide prevention., Competing Interests: The authors declare no conflicts of interest.

Introduction: The COVID-19 pandemic has had major economic, social and psychological consequences for adolescents and young adults. It is unclear whether those with a history of adverse childhood experiences (ACEs) were particularly vulnerable. We examined whether a history of ACEs was associated with financial difficulties, lack of emotional support, feeling stressed/anxious, feeling down/depressed, increased alcohol and/or cannabis use and increased conflict with parents, siblings and/or intimate partners among 16- to 21-year-olds during the pandemic., Methods: Data were collected in November and December 2020 from respondents aged 16 to 21 years (n = 664) participating in the longitudinal and intergenerational Well-being and Experiences Study (Wave 3) conducted in Manitoba, Canada. Age-stratified associations between ACEs and pandemic-related stressors/symptoms were examined with binary and multinomial logistic regression., Results: A history of ACEs was associated with pandemic-related financial difficulties (adjusted relative risk ratio [aRRR] range: 2.44-7.55); lack of emotional support (aRRR range: 2.13-26.77); higher levels of feeling stressed/anxious and down/depressed (adjusted odds ratio [aOR] range: 1.78-5.05); increased alcohol and cannabis use (aOR range: 1.99-8.02); and increased relationship conflict (aOR range: 1.98-22.59). Fewer associations emerged for older adolescents and these were not to the same degree as for young adults., Conclusion: Adolescents and young adults with a history of ACEs reported increased odds of pandemic-related stressors and symptoms, and may need more resources and greater support compared to peers without an ACE history. Differences in results for adolescents and young adults suggest that interventions should be tailored to the needs of each age group., Competing Interests: Tracie O.

Evidence about how the pandemic affected household violence in Canada is mixed, but inarguably, the risk factors increased. This study used data from the 2020 Canadian Perspective Survey Series and the 2020 and 2021 Surveys of COVID-19 and Mental Health to examine the following: changes in the prevalence of concern about violence in individuals' own homes during the pandemic; the characteristics of those who expressed concern; and the prevalence of concerns for specific household members. Among Canadians, the prevalence of concern about violence in individuals' own homes decreased significantly between July and Fall 2020 (5.8% to 4.2%). Among women, the characteristics that were significantly associated with higher adjusted odds of concern about household violence included larger household size and lower household income. Lower education among women was associated with lower adjusted odds of concern. The associations with higher adjusted odds of concern among men included: being an immigrant, larger household size, and lower household income. From Fall 2020 to Spring 2021, the prevalence of concerns for oneself and for a child/children increased (1.7% to 2.5% and 1.0% to 2.5%, respectively), but concern for other adults in the household decreased (1.9% to 1.2%). Ongoing surveillance is needed to understand vulnerable populations' exposure to household violence and to inform policies and programs.

Introduction: Data from the first round of the nationally representative Survey on COVID-19 and Mental Health (SCMH) revealed that the prevalence of recent suicidal ideation in the fall of 2020 in Canada did not differ significantly from that in the pre-pandemic period in 2019. The objective of the present study was to reassess the prevalence of recent suicidal ideation in the spring of 2021., Methods: The prevalence of suicidal ideation among adults in Canada was examined using the 2021 SCMH (conducted between February 1 and May 7, 2021), and it was compared with the prevalence in the 2019 Canadian Community Health Survey. Unadjusted logistic regression analysis was used to assess the differential likelihood of reporting suicidal ideation in population subgroups., Results: Among adults in Canada, the prevalence of suicidal ideation since the pandemic began was 4.2%, which was significantly higher than the pre-pandemic prevalence of 2.7% in 2019. A statistically significant increase in prevalence was observed among females and males, age groups younger than 65, and several other sociodemographic groups, as well as in British Columbia, the Prairie provinces and Ontario. People who were younger than 65 years, were born in Canada, had lower educational attainment, or were never married were significantly more likely to report suicidal ideation than others during the pandemic., Conclusion: As the second year of the pandemic began, the prevalence of recent suicidal ideation in Canada was higher than it had been before the pandemic in 2019. Continuous monitoring of suicide-related outcomes and risks is necessary so that population-level changes can be detected and inform public health action.

Introduction: Since the outbreak of COVID-19, numerous studies from around the world have reported declines in mental health. However, most of these studies were of low-to-moderate quality and many were based on convenience samples or used mental health measures with low validity, or both. Consequently, it has been difficult to draw conclusions., Methods: Both the 2020 Survey on COVID-19 and Mental Health (SCMH) and the Canadian Community Health Survey (CCHS) (2015-2019) used the Patient Health Questionnaire-9 to screen for major depressive disorder (MDD) in adults aged 18 or older. The prevalence of MDD was compared between the SCMH and the CCHS. Risk and protective factors for MDD in the SCMH were examined using bivariate and logistic regression analyses., Results: Based on SCMH data, 15.2% (95% CI: 14.2-16.2) of Canadians screened positive for MDD. The prevalence of MDD was more than two times higher in the SCMH (during COVID-19) than in the CCHS (predating COVID-19). In bivariate analysis, Canadians reporting five or more COVID-19-related risk factors were close to 30 times more likely to have MDD than those reporting no risk factors. Mastery and a sense of community belonging were protective factors for MDD., Conclusion: After remaining stable for two decades, the prevalence of depression among Canadians increased substantially with the onset of COVID-19. Ongoing monitoring of this common condition associated with major morbidity is vital to determine if elevated levels of MDD persist as we progress through and beyond future waves of COVID-19., Competing Interests: The authors have no conflicts of interest.

Most of the research on caregiver vulnerabilities associated with the perpetration of child maltreatment (CM) focuses on perpetrators of child physical or sexual abuse. Less is known about the association of specific caregiver vulnerabilities and the risk of other CM types or how these vulnerabilities are related to child harm. The aim of the study was to examine the association of caregiver's vulnerabilities with types of substantiated CM and child physical and mental/emotional harm as a result of maltreatment. Data were from the Canadian Incidence Study of Reported Child Abuse and Neglect collected in 2008 (CIS-2008). The CIS-2008 consisted of investigations of children aged 15 years and younger from 112 child welfare sites across Canada ( N = 15,980). Descriptive statistics and logistic regression were used to examine relationships between caregiver vulnerabilities and outcomes of interest. Caregiver vulnerabilities were prevalent among cases of CM substantiated by child welfare agencies across Canada. Low social support, domestic violence, mental health issues, and substance abuse problems were noted among a substantial proportion of abusive caregivers. Caregiver cognitive impairments and domestic violence perpetration were associated with increased odds of child physical harm, but only among children aged 0 to 4 years. Most individual types of caregiver vulnerabilities were associated with increased odds of child mental or emotional harm across all child age groups. Insight into caregiver vulnerabilities associated with the perpetration of CM may help inform intervention targets prior to a family's involvement in the child welfare system.

The purpose of this study was to examine associations between three subtypes of childhood maltreatment (physical abuse, sexual abuse, and exposure to intimate partner violence) and two forms of adult police contact (criminality, victimization) using nationally representative Canadian data. Presence of a mental health disorder was also explored as a potential mediating variable in these associations. The weighted sample included 23,846 adult participants from the 2012 Canadian Community Health Survey-Mental Health. Logistic and multinomial regression analyses examined associations among individual and multiple exposures to subtypes of childhood maltreatment with police contact. The Sobel test was used to assess the mediating effect of mental health disorders. Adjusting for sociodemographic variables, results indicated that all maltreatment subtypes were significantly associated with increased odds of both forms of police contact (adjusted odds ratios ranged from 2.06 to 2.95). Presence of a mental health disorder was a partial mediator in the associations between child maltreatment and both forms of adult police contact (adjusted odds ratios ranged from 1.52 to 2.32). In addition, a dose-response relationship was observed for victimization; as the number of subtypes of maltreatment increased, there was an incremental increase in risk of victimization. Future efforts are needed to prioritize child maltreatment prevention, trauma-informed approaches, mental health awareness, and training in law enforcement.

Background: The suicide rate in Canada decreased by 24% during the past four decades. However, rates vary between provinces and territories, and not all jurisdictions experienced the same changes. This study examined suicide rates over time in the province of Newfoundland and Labrador., Methods: We used cross-sectional surveillance data from the Canadian Vital Statistics Death Database to examine suicide rates in Newfoundland and Labrador from 1981 to 2018. We calculated annual age-standardized suicide mortality rates and used joinpoint regression to estimate the average annual percent change (AAPC) in suicide rates overall and by sex, age group, and means of suicide., Results: From 1981 to 2018, 1759 deaths by suicide were recorded among people in Newfoundland and Labrador. The age-standardized suicide mortality rate increased more than threefold over the study period, from 4.6 to 15.4 deaths per 100,000. The suicide rate was higher among males than females, and accounted for 83.1% of suicide deaths (n = 1462); the male-to-female ratio of suicide deaths was 4.9 to 1. The average annual percent change in suicide rates was higher among females than males (6.3% versus 2.0%). Age-specific suicide rates increased significantly for all age groups, except seniors (aged 65 or older); the largest increase was among youth aged 10 to 24 years old (AAPC 3.5; 95% CI, 1.6 to 5.5). The predominant means of suicide was hanging/strangulation/suffocation, which accounted for 43.8% of all deaths by suicide., Conclusions: The suicide rate in Newfoundland and Labrador increased steadily between 1981 and 2018, which was in contrast to the national rate decline. The disparity between the provincial and national suicide rates and the variations by sex and age underscore the need for a public health approach to prevention that accounts for geographic and demographic differences in the epidemiology of suicide.

Background: Ongoing surveillance of the means of suicide is necessary for effective prevention. We examined how mortality rates owing to different means of suicide changed in Canada from 1981 to 2018., Methods: We obtained data from 1981 to 2018 on suicide deaths of individuals aged 10 years and older, from the Canadian Vital Statistics Death Database. We used joinpoint regression analysis to examine changes over time in the suicide mortality rate for the 3 most common means of suicide., Results: The age-standardized suicide mortality rate declined in earlier decades for both sexes, but did not significantly change in recent decades for either sex. The age-standardized rate of suicide by suffocation increased from 1993 for females (2.1% per year) and from 1996 for males (0.4% per year). The age-standardized rate of suicide by poisoning decreased for females (2.2% per year) and males (2.1% per year) from 1981 to 2018. The age-standardized rate of suicide by firearm decreased from 1981 to 2008 (7.4% per year) but did not significantly change there-after for females; for males, it decreased 2.1% per year from 1981 to 1993 and 5.7% per year from 1993 to 2007, but did not significantly change thereafter., Interpretation: For both sexes, the rate of suicide by poisoning is decreasing, the rate of suicide by suffocation is increasing, and the rate of suicide by firearm has not significantly changed in the last decade. Given the high proportion of suicide deaths by suffocation, its increasing rate and the difficulty of restricting the means of suffocation, other approaches to suicide prevention are needed., Competing Interests: Competing interests: None declared., (© 2021 Joule Inc. or its licensors.)

Background: Population-level prevalence estimates for a broad range of adverse childhood experiences (ACEs), which are known to affect health across the lifespan, are currently unavailable in Canada. The purpose of this study was to estimate the prevalence of individual ACEs by sociodemographic factors among middle-aged and older adults., Methods: Data for this cross-sectional analysis were obtained from the first follow-up (2015-2018) of the Canadian Longitudinal Study on Aging (baseline recruitment from 2011 to 2015). Participants included individuals aged 45-85 years and residing in the community in the 10 Canadian provinces. Exposure to ACEs was assessed using a retrospective, self-report questionnaire. Logistic regression was used to obtain the adjusted prevalence estimates of ACEs within groups formed by the sociodemographic characteristics and each variable was adjusted for all other sociodemographic variables., Results: Of the 44 817 participants in the first follow-up, 61.6% (weighted) reported exposure to at least 1 ACE. Exposure to physical abuse (weighted prevalence of 25.7%), intimate partner violence (22.4%) and emotional abuse (21.8%) were the most prevalent types of ACEs. Individuals younger than 65 years (born in 1950-1969), with no postsecondary education or education below a bachelor's degree, or with annual household income less than $20 000 reported greater exposure to ACEs. Reporting for many ACEs was higher among women and those of nonheterosexual orientation. Overall, British Columbia, Alberta, Manitoba, Ontario and Quebec reported relatively higher prevalence for several examined categories of ACEs., Interpretation: Adverse childhood experiences were highly prevalent across all demographic groups with substantial heterogeneity in the distribution among the middle and older age population. The high prevalence of ACEs and their potential negative consequences on health and well-being emphasize the need to develop and promote trauma-informed care to assist individuals affected by ACEs., Competing Interests: Competing interests: None declared., (© 2021 Joule Inc. or its licensors.)

Children exposed to intimate partner violence (CE-IPV) are at increased risk for later health and social difficulties. To date, studies have primarily focused on CE-IPV as a unitary construct; this may lead to the mistaken assumption that all subtypes of CE-IPV (i.e., exposure to direct or indirect physical abuse, or exposure to emotional abuse) are equally harmful requiring similar responses from child welfare services. The purpose of this study was to examine child welfare responses by CE-IPV subtype in a large Canadian child welfare sample. Using data from the Canadian Incidence Study of Reported Child Abuse and Neglect-2008 ( N = 2,184), we examined child welfare responses to CE-IPV subtypes or their co-occurrence. Information was obtained from child welfare workers' reports. Cases with co-occurring subtypes of CE-IPV were more likely to be substantiated and involved multiple incidents compared with that with single CE-IPV subtypes. Cases with direct physical CE-IPV and co-occurring CE-IPV were also more likely to remain open and have an application considered or made to child welfare court. Exposure to emotional IPV was the least likely to warrant interventions by welfare services, including referrals to specialized services. These results suggest that within CE-IPV subtypes, there is evidence of different responses (recommendations and services) once a case has been opened by a worker. Future research is needed to examine the effectiveness of the responses and outcomes for children following child welfare interventions.

Background: Childhood 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., Methods: Based 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., Results: For 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., Conclusions: The 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.

Background: The Canadian Hospitals Injury Reporting Prevention Program (CHIRPP) is a sentinel surveillance program that collects and analyzes data on injuries and poisonings of people presenting to emergency departments (EDs) at 11 pediatric and eight general hospitals (currently) across Canada. To date, CHIRPP is an understudied source of child maltreatment (CM) surveillance data. This study: (1) describes CM cases identified in the CHIRPP database between1997/98 to 2010/11; (2) assesses the level of CM case capture over the 14-year period and; (3) uses content analysis to identify additional information captured in text fields., Methods: We reviewed cases of children under 16 whose injuries were reported as resulting from CM from 1997/98 to 2010/11. A time trend analysis of cases to assess capture was conducted and content analysis was applied to develop a codebook to assess information from text fields in CHIRPP. The frequency of types of CM and other variables identified from text fields were calculated. Finally, the frequency of types of CM were presented by age and gender., Results: A total of 2200 CM cases were identified. There was a significant decrease in the capture of CM cases between 1999 and 2005. Physical abuse was the most prevalent type (57%), followed by sexual assault (31%), unspecified maltreatment (7%), injury as the result of exposure to family violence (3%) and neglect (2%). Text fields provided additional information including perpetrator characteristics, the use of drugs and/or alcohol during the injury event, information regarding the involvement of non-health care professionals, whether maltreatment occurred during a visitation period with a parent and, whether the child was removed from their home., Conclusions: The findings from this initial study indicate that CHIRPP could be a complimentary source of CM data. As an injury surveillance system, physical abuse and sexual assault were better captured than other types of CM. Text field data provided unique information on a number of additional details surrounding the injury event, including risk factors.

Objective: To establish whether there is a relationship between the frequency and severity of different types of childhood maltreatment and adulthood arthritis., Methods: Analysis of the 2012 Canadian Community Health Survey-Mental Health included 21,889 respondents ages ≥18 years. Severity and frequency of childhood physical abuse (CPA), and childhood sexual abuse (CSA), and the frequency of childhood exposure to intimate partner violence (CEIPV) were assessed by asking about "things that may have happened to you before you were 16 in your school, in your neighborhood, or in your family." Respondents were also asked about chronic conditions diagnosed by a health professional, including arthritis. Covariates were sociodemographic characteristics, health risk variables (e.g., obesity), mental disorders, and a count of other chronic conditions. Multivariate logistic regression analysis was used to examine associations between childhood maltreatment and arthritis., Results: A total of 17.5% of respondents reported arthritis. A higher prevalence of arthritis was observed for those who had experienced severe and/or frequent childhood maltreatment (32% for CPA and 27% for both CSA and CEIPV). These relationships persisted after controlling for sociodemographic variables. After controlling for all covariates, arthritis remained independently associated with severe and/or frequent CPA (dose-response relationship) and frequent CEIPV., Conclusion: We found that the greater the frequency and severity of childhood maltreatment, the greater the magnitude of association with arthritis. This might reflect the role of the enduring immune and metabolic abnormalities and chronic inflammation associated with childhood maltreatment in the etiopathogensis of osteoarthritis (OA) or be an indicator of the role of joint injury in causing OA., (© 2018, American College of Rheumatology.)

Objective: To provide evidence of trends in child sexual abuse (CSA) in Canada., Methods: Using data from 15,801 males and 18,669 females who responded to the 2014 General Social Survey (GSS), we compared the prevalence of CSA by age cohorts. Age cohort patterns were examined for several sub-populations including males, females, Indigenous peoples, and people living in low-income households., Results: After an increase in the post-World War II period, there has been a decline in CSA in Canada since the early 1990s. Findings indicate a decline for both sexes; although, the evidence is more compelling for females. There is also evidence of a decline for Indigenous peoples, for those living in low-income households, and regardless of the relationship to the perpetrator (i.e., family member, a teacher/professor/tutor, a babysitter, a nanny, other non-family member but known to the respondent, or a stranger)., Conclusions: In Canada, evidence from 3 retrospective population surveys suggests a decline in CSA since the early 1990s. However, given the associated harm, continued progress to the eradication of CSA is essential.

Objectives: This study investigated associations between three types of child maltreatment (exposure to intimate partner violence, sexual, and physical abuse) and multimorbidity (chronic physical conditions, pain conditions, and mental disorders) in adults., Methods: Multinomial logistic regression was used to analyze weighted data from the 2012 Canadian Community Health Survey (CCHS - MH 2012), a representative population sample (N = 23,846) of respondents ages 18+., Results: All three subtypes of child maltreatment independently predicted increased odds of experiencing multimorbidity as an adult, while adjusting for covariates (adjusted odds ratios ranged from 1.34 (95% CI = 1.00, 1.80) to 4.87 (95% CI = 2.75, 8.63)). A dose-response relationship between the number of child maltreatment subtypes and risk for multimorbidity was also observed (adjusted odds ratios ranged from 1.38 (95% CI = 1.11, 1.73) to 10.96 (95% CI = 6.12, 19.64))., Conclusion: The current results highlight the importance of considering a range of childhood adversities and suggest that public health approaches that aim to decrease the prevalence and severity of child maltreatment have the potential to ameliorate adult multimorbidities. Future research is encouraged to investigate these issues using longitudinal population-level data.

Much of what is known about child abuse in Canada has come from reported cases of child abuse and at-risk samples, which likely represent the most severe cases of child abuse in the country. The objective of the current study is to examine the prevalence of a broad range of child abuse experiences (physical abuse, sexual abuse, and exposure to IPV) and investigate how such experiences and sociodemographic variables are related to contact with child protection organizations in Canada using a representative general population sample. Data were drawn from the 2012 Canadian Community Health Survey: Mental Health collected from the 10 provinces using a multistage stratified cluster design (n=23,395; household response rate=79.8%; aged 18 years and older). Physical abuse only (16.8%) was the most prevalent child abuse experience reported with the exposure to specific combinations of two or more types of child abuse ranging from 0.4% to 3.7%. Only 7.6% of the adult population with a history of child abuse reported having had contact with child protection organizations. Experiencing all three types of child abuse was associated with the greatest odds of contact with child protection organizations (AOR=15.8; 95% CI=10.1 to 24.6). Physical abuse only was associated with one of the lowest odds of contact with child protection organizations. Preventing child abuse is widely acknowledged as an important, but challenging public health goal. Strategies to increase reporting of child abuse may help to protect children and to connect families with necessary services. One obvious priority would be physical abuse., (Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Objective: Identifying child and household characteristics that are associated with specific child maltreatment types and child functional impairment are important for informing prevention and intervention efforts. Our objectives were to examine the distribution of several child and household characteristics among substantiated child maltreatment types in Canada; to determine if a specific child maltreatment type relative to all other types was associated with increased odds of child functional impairment; and to determine which child and household characteristics were associated with child functional impairment., Method: Data were from the Canadian Incidence Study of Reported Child Abuse and Neglect (collection 2008) from 112 child welfare sites across Canada (n = 6163 children)., Results: Physical abuse, sexual abuse, and emotional maltreatment were highly prevalent among children aged 10 to 15 years. For single types of child maltreatment, the highest prevalence of single-parent homes (50.6%), social assistance (43.0%), running out of money regularly (30.7%), and unsafe housing (30.9%) were reported for substantiated cases of neglect. Being male, older age, living in a single-parent home, household running out of money, moving 2 or more times in the past year, and household overcrowding were associated with increased odds of child functional impairment., Conclusions: More work is warranted to determine if providing particular resources for single-parent families, financial counselling, and facilitating adequate and stable housing for families with child maltreatment histories or at risk for child maltreatment could be effective for improving child functional outcomes.

Children exposed to intimate partner violence (IPV) are at increased risk of experiencing behavioral difficulties including externalizing and internalizing problems. While there is mounting evidence about mental health problems in children exposed to IPV, most of the research to date focuses on IPV exposure as a unitary, homogeneous construct. The purpose of this study was to examine the association between subtypes of IPV exposure on child functioning and presence of harm within a child welfare sample. Given the evidence of the "double whammy" effect, co-occurring IPV exposure was also examined. Using data from the Canadian Incidence Study of Reported Child Abuse and Neglect - 2008 (n=2,184) we examined whether specific IPV exposure subtypes or their co-occurrence resulted in a greater risk of child maladjustment. Information was obtained from child welfare workers' reports. Caregiver and household risk factors were also examined. Co-occurring IPV exposure resulted in the greatest risk for reported child maladjustment. Exposure to emotional IPV and direct physical IPV were significantly associated with increased risk of internalizing problems and presence of harm. Caregiver mental health and lack of social support emerged as significant risk factors for behavior problems. This study adds to the evidence that exposure to subtypes of IPV may be differentially related to child functioning. Given that risk factors and child functioning is part of the decision-making framework for case worker referrals, this study provides important preliminary evidence about how the child welfare system operates in practice with respect to sub-types of exposure to IPV. These findings suggest that intervening with children exposed to different types of IPV may require a tailored approach., (Copyright © 2014. Published by Elsevier Ltd.)

Objectives: To identify factors associated with repeat emergency department (ED) presentations for suicide-related behaviors (SRB) - hereafter referred to as repetition - among children/youth to aid secondary prevention initiatives. To compare rates of repetition in children/youth with substantiated maltreatment requiring removal from their parental home with their peers in the general population., Methods: A population-based (retrospective) cohort study was established for children/youth with a first ED SRB presentation at risk for repetition in the Province of Ontario, Canada between 1 January 2004 and 31 December 2008. Children/youth legally removed from their parental home because of substantiated maltreatment (n=179) and their population-based peers (n=6,305) were individually linked to administrative health care records over time to ascertain social, demographic, and clinical information and subsequent ED presentations for SRB during follow-up. These children/youth were described and their repetition-free probabilities over time compared. To identify factors associated with repetition we fit multivariable, recurrent event survival analysis models stratified by repetition and present unadjusted and adjusted hazard ratios (HRs) and 95% confidence intervals (CIs)., Results: Children/youth with substantiated maltreatment (as noted) were two times more likely to have repetition than their peers after adjustments for social, demographic, and clinical factors (conditional on prior ED SRB presentations). A number of these factors were independently associated with repetition. No one factor distinguished between having a first and second repetition nor was more strongly associated with repetition than another., Conclusions: The risk of repetition is higher in children with substantiated maltreatment (as noted) than their peers. No one factor stood out as predictive of repetition. Implications for secondary prevention initiatives include a non-selective approach, sensitive to family difficulties and the need to better contextualize repetition and harness data linkages., (Copyright © 2012 Elsevier Ltd.

Aim: Interest in understanding the problem of child maltreatment is widely shared by governments, organizations of physicians, and others. Our objective was to describe and discuss sources of information in Canada that could be used to help understand the nature and scope of the problem, either within any province or territory, or across all of Canada., Methods: A series of web searches and a focused literature review were conducted to identify sources of child maltreatment information. Government departments responsible for child welfare were also contacted on an as-needed basis in order to identify additional sources., Results: Identified sources included: child welfare administrative provincial/territorial data and reports based on those data, other child welfare information, surveys of child protection workers and shelter workers, mortality/morbidity data, police data, direct surveys of children and their parents, and the 2011 Canadian census. Each type of source had strengths and limitations in terms of how it could describe the nature and scope of the problem of child maltreatment., Conclusion: Increased use of morbidity and mortality data, data linking, expanding existing databases, and increasing the use of general population surveys could expand understanding of child maltreatment in Canada.

Objective: This paper builds upon the analyses presented in two companion papers (Fluke et al., 2010; Fallon et al., 2013) using data from the 1998 and 2003 cycles of the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS-1998 and CIS-2003) to examine the influence of clinical and organizational characteristics on the decision to place a child in out-of-home care at the conclusion of a child maltreatment investigation. This paper explores various model specifications to explain the effect of an agency-level factor, proportion of Aboriginal reports, which emerged as a stable and significant factor through the two data collection cycles. It addresses the issue of data comparability between the two cycles and explores various re-specifications and descriptive analyses of reported models to evaluate their solidity with regards to the sampling schemes and the precise contribution of a multi-level specification., Methods: The decision to place a child in out-of-home care was examined using data from the CIS-2003. This child welfare dataset collected information about the results of nearly 12,000 child maltreatment investigations as well as a description of the characteristics of the workers and organization responsible for conducting those investigations. Multi-level statistical models were developed using MPlus software, which can accommodate dichotomous outcome variables and are more reflective of decision-making in child welfare. The models are thus multi-level binary logistic regressions., Results: Final models revealed that two agency-level variables, 'Education degree of majority of workers' and 'Degree of centralization in the agency' clarify the nature of the effect of 'Proportion of Aboriginal reports', a stable, key second level predictor of the placement decision. The comparability of the effect of this agency-level variable across the 1998 and 2003 cycles becomes further evident through this analysis. By using a unified database including both cycles and various specifications of models, the comparability was found to be robust, in addition to clarifying the precise contribution of a multi-level specification., Conclusions: This third paper in a series establishes the 'Proportion of Aboriginal reports' received by the child welfare agency as an important agency level predictor associated with a child's likelihood of being placed in the Canadian child protection system. While the more complex models give support to the notion that unequal resources subtend those results, more analyses are needed to confirm this hypothesis. Unequal resources for agencies with larger Aboriginal caseloads may explain the persistence of the results. These findings suggest that specific resource constraints related to worker education may be explanatory., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Objective: Fluke et al. (2010) analyzed Canadian Incidence Study on Reported Child Abuse and Neglect (CIS) data collected in 1998 to explore the influence of clinical and organizational characteristics on the decision to place Aboriginal children in an out-of-home placement at the conclusion of a child maltreatment investigation. This study explores this same question using CIS data collected in 2003 which included a larger sample of Aboriginal children and First Nations child and family service agencies., Methods: The decision to place a child in an out-of-home placement was examined using data from the Canadian Incidence Study of Reported Child Abuse and Neglect-2003 and a reanalysis of CIS-1998 data (Fluke et al., 2010). The CIS-2003 dataset includes information on nearly 12,000 child maltreatment investigations from the time of report to case disposition. The CIS-2003 also captures information on the characteristics of investigating workers and the child welfare organizations for which they work. Multi-level statistical models were developed to analyze the influence of clinical and organizational variables using MPlus software. MPlus allows the use of dichotomous outcome variables, which are more reflective of decision-making in child welfare and facilitates the specific case of the logistic link function for binary outcome variables under maximum likelihood estimation., Results: Final models revealed the proportion of investigations conducted by the child welfare agency involving Aboriginal children was a key single agency level predictor of the placement decision. Specifically, the higher the proportion of investigations of Aboriginal children, the more likely placement was to occur. Contrary to the findings in the first paper (Fluke et al., 2010), individual Aboriginal status also remained significant in the final model at the first level., Conclusions: Further analysis needs to be conducted to further understand individual and organizational level variables that may influence decisions regarding placement of Aboriginal children. There is also a need for research that is sensitive to differences among, and between, Métis, First Nations and Inuit communities. Results are not generalizable to Québec because data from this province were excluded., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Objectives: This article reviews research, policy and programming in Australia, Canada and the US on the child welfare response to EDV., Method: The review draws on searches of standard research databases, interviews with researchers and practitioners, and the authors' own research., Results: Although EDV is underreported, across studies 7% to 23% of youths in general population surveys experienced EDV, 36-39% of youth in DV cases have witnessed the violence, and 45-46% of primary caregivers in child maltreatment investigations have experienced DV. Mandatory reporting can increase the number of cases that come to the attention of child welfare, but without resources for training and programming can lead to inappropriate reports, lack of referral for further assessment, and strains on the child welfare system. Improving the child welfare response to EDV can include collaboration between child welfare workers and DV advocates; increased training on screening for DV; new protocols on DV; and dedicated DV staffing within child welfare agencies. In recent years, policy and program attention to EDV has also been embedded within broader national efforts to protect children from violence and maltreatment. Differential response models that eschew investigation in favor of assessment and service delivery hold promise for families with DV., Conclusions: Empirical data are limited, but current research and practice experience suggest that child welfare agencies seeking to improve the response to EDV should collaborate with other disciplines involved with preventing and responding to DV, seek resources to support training and programming, consider methods that avoid stigmatizing parents, and build in a program evaluation component to increase knowledge about effective practice., (Copyright © 2012 Elsevier Ltd.

Objective: This article critically assesses and reviews analyses derived from three cycles of the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS) published between 2001 and October 2011., Methods: Articles were retrieved from the Public Health Agency of Canada's data request records, which tracked database access and ensuing publications. The included articles were reviewed and appraised independently by the authors., Synthesis: Overall, 37 peer-reviewed articles using CIS data were included in the review. These articles revealed an increased likelihood of substantiation or placement if investigations 1) uncovered the presence of emotional or physical harm in a child, 2) involved older children, 3) identified the presence of risk indicators in caregivers, or 4) documented unstable or unsafe housing. A similar proportion of articles used a descriptive or multivariate approach to analyze CIS data, and strengths and limitations were identified., Conclusion: Researchers have analyzed and interpreted the CIS extensively, although several issues are understudied - such as neglect and emotional maltreatment - especially using multivariate approaches. We hope this review will contribute to helping address gaps in the CIS literature.

Purpose: To examine five types of child maltreatment and other risk correlates to establish associations with anxiety and/or depression confirmed or suspected in children investigated by child welfare services., Methods: The present study used the data of a subsample of 10-15-year-olds (n = 4,381) investigated by child welfare services across Canada obtained from the Canadian Incidence Study of Reported Child Abuse and Neglect-2003. The analysis took into account the nested structure of the data by considering the variability existing among families and the clustering of siblings within them. Several models were analyzed for the construction of the presented hierarchical model. Striving for parsimony, we included only statistically significant variables in the final model., Results: The strongest associations were found with child substance abuse, substantiated emotional maltreatment, primary caregiver's mental health problems, and substantiated sexual abuse. Among the child maltreatment variables, substantiated physical abuse and substantiated exposure to domestic violence did not show any statistically significant associations with anxiety and/or depression in the model., Conclusion: This analysis helped us in understanding child maltreatment and other adverse experiences in childhood that were related to anxiety and/or depression, which can further aid in the development of mental health and child welfare policies and programs., (Crown Copyright © 2011.

Objective: This article reviewed the different surveillance systems used to monitor the extent of reported child maltreatment in North America., Methods: Key measurement and definitional differences between the surveillance systems are detailed and their potential impact on the measurement of the rate of victimization. The infrastructure requirements, quality of information, timely access to data and the usefulness for child welfare policy are compared and contrasted and a summary table of the type of information by each system is presented., Results: Two studies collect data regarding the extent and nature of child maltreatment using survey methodology reported to professionals: the United States National Incidence Study of Child Abuse and Neglect (NIS) and the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS), and the United States National Child Abuse and Neglect Data System (NCANDS) uses administrative data methods to collect annual case-level and state data., Practice Implications: The purpose of this comparison is to assist researchers and policy analysts with interpreting data from these studies as well as to help officials from other countries in developing surveillance systems that are appropriately adapted to their needs., (Copyright (c) 2009 Elsevier Ltd.

A media strategy was developed to disseminate Canadian child maltreatment surveillance data. Print media were systematically searched and 29 articles reporting on the data were retrieved. Using content analysis, the articles were analyzed to assess informational accuracy and to understand how the media framed the issue of maltreatment. This analysis permits the authors to share "lessons learned," which will be helpful for researchers disseminating child maltreatment data through the media.

Reliable national child maltreatment data are needed for developing and modifying policies aimed at preventing child maltreatment and helping child victims of maltreatment. Health Canada hosted a daylong forum in 2002 to solicit feedback from senior Government of Canada policy and program officials involved in child welfare programs and research in regard to the data collected in the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS). This article reviews the discussions and debates regarding the utility of the CIS data for government policy makers and reflects on the implications for surveillance and knowledge in the area of child maltreatment. The key themes are definitions and measurement issues, the value of enhanced and additional data, and challenges to linking research and practice.
