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]

The article focuses on the creation and growth of the national surveillance systems in Canada as well as their effect on chronic injury prevention and chronic disease. Topics discussed include the historical background of the federal department and agency structure for chronic disease surveillance, the significant role of the Laboratory Centre for Disease Control, and the primary chronic disease surveillance initiatives.

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. [ABSTRACT FROM AUTHOR]

The relationships between child maltreatment and the media have been examined in several recent papers. In the authors' previous work representations of neglect, and physical and emotional (but not sexual) child abuse were found in a content analysis of 45 Disney films released from 1937-2006. (Two additional Disney films, released in 2007, are included in the present analysis.) While conducting the content analysis the authors noted unexpected content in ten films. This paper presents an exploratory analysis of depictions of unwanted personal contact and situations that suggest risk due to unsupervised contact with malevolent or questionable strangers. These depictions are described and analyzed, their potential influences on child audiences are discussed, and implications for new research directions are suggested.

The goal of this study was to examine the association of physical and sexual abuse in childhood, poverty, parental substance abuse problems and parental psychiatric problems with disability due to physical health problems in a community sample of women. We included 4,243 women aged 15-64 years from the Ontario Mental Health Supplement in the analysis. The associations were tested by multiple logistic regression. Ten percent of women had a disability due to physical health problems. Among women with a disability, approximately 40% had been abused while growing up. After controlling for income and age, disability showed the strongest association with childhood physical abuse, parental education less than high school and parental psychiatric disorder. The association with child sexual abuse was not significant. Given the high correlation between abuse and disability due to physical health problems, it is important to investigate approaches to identify women who are at increased risk of subsequent impairment.

Margot E Shields, Wendy E Hovdestad, Charles P Gilbert, Lil E Tonmyr Public Health Agency of Canada, Ottawa, ON, Canada Objective: The aim of this study was to examine the associations between childhood maltreatment (CM) and COPD in adulthood.Methods: Data were from 15,902 respondents to the 2012 Canadian Community Health Survey – Mental Health. Multiple logistic regression models were used to examine associations between CM and COPD and the role of smoking and mental and substance use variables as mediators in associations.Results: COPD in adulthood was related to CM, with associations differing by sex. Among females, COPD was related to childhood physical abuse (CPA), childhood sexual abuse, and childhood exposure to intimate partner violence, but in the fully adjusted models, the association with CPA did not persist. Among males, COPD was related to childhood exposure to intimate partner violence and severe and frequent CPA, but these associations did not persist in the fully adjusted models.Conclusion: Results from this study establish CM as a risk factor for COPD in adulthood. A large part of the association is attributable to cigarette smoking, particularly for males. These findings underscore the importance of interventions to prevent CM as well as programs to assist victims of CM in dealing with tobacco addiction.

Based on a nationally representative survey of the Canadian population conducted in 2019/2020, this study examined the prevalence and determinants of non-physical Intimate partner violence (NP-IPV). NP-IPV was defined as experiences of emotional abuse, controlling behaviours, or economic abuse during the past five years. Women (17.3%) and men (16.9%) were equally likely to report NP-IPV, often without co-occurring physical/sexual IPV. For both genders, the risk of NP-IPV decreased with age, and increased with financial strain and having a disability. Childhood maltreatment (sexual abuse, emotional abuse, and exposure to emotional IPV for women, and sexual abuse and emotional abuse for men) was associated with an increased likelihood of reporting NP-IPV in adulthood. Other risk factors included heavy episodic drinking (self and/or spouse/partner) for women and living in a neighbourhood with high levels of social disorder for men. Having confidence in the police was a protective factor for both genders. These associations generally persisted in regression analyses controlling for co-occurring physical/sexual IPV. Future research should focus on methods of preventing NP-IPV and the development of gender-specific interventions to reach and support those who experience NP-IPV. Furthermore, there is a need to improve and standardize measures of NP-IPV., (© The Author(s) 2024.

Background: We investigated the effectiveness of Nurse-Family Partnership (NFP), a prenatal-to-age-two-years home-visiting programme, in British Columbia (BC), Canada., Methods: For this randomised controlled trial, we recruited participants from 26 public health settings who were: <25 years, nulliparous, <28 weeks gestation and experiencing socioeconomic disadvantage. We randomly allocated participants (one-to-one; computer-generated) to intervention (NFP plus existing services) or comparison (existing services) groups. Prespecified outcomes were prenatal substance exposure (reported previously); child injuries (primary), language, cognition and mental health (problem behaviour) by age two years; and subsequent pregnancies by 24 months postpartum. Research interviewers were masked. We used intention-to-treat analyses. (ClinicalTrials.gov, NCT01672060.) RESULTS: From 2013 to 2016 we enrolled 739 participants (368 NFP, 371 comparison) who had 737 children. Counts for child injury healthcare encounters [rate per 1,000 person-years or RPY] were similar for NFP (223 [RPY 316.17]) and comparison (223 [RPY 305.43]; rate difference 10.74, 95% CI -46.96, 68.44; rate ratio 1.03, 95% CI 0.78, 1.38). Maternal-reported language scores (mean, M [SD]) were statistically significantly higher for NFP (313.46 [195.96]) than comparison (282.77 [188.15]; mean difference [MD] 31.33, 95% CI 0.96, 61.71). Maternal-reported problem-behaviour scores (M [SD]) were statistically significantly lower for NFP (52.18 [9.19]) than comparison (54.42 [9.02]; MD -2.19, 95% CI -3.62, -0.75). Subsequent pregnancy counts were similar (NFP 115 [RPY 230.69] and comparison 117 [RPY 227.29]; rate difference 3.40, 95% CI -55.54, 62.34; hazard ratio 1.01, 95% CI 0.79, 1.29). We observed no unanticipated adverse events., Conclusions: NFP did not reduce child injuries or subsequent maternal pregnancies but did improve maternal-reported child language and mental health (problem behaviour) at age two years. Follow-up of long-term outcomes is warranted given that further benefits may emerge across childhood and adolescence., (© 2023 The Authors.

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: Guided by the bioecological model, the purpose of this study was to examine the associations of (1) individual level factors (sociodemographic, health behaviour and mental health), (2) family (micro) level COVID-19 experiences (difficulty with household management, managing child mood and behaviour, and pandemic-related positive experiences) and (3) community (macro) level factors (residential instability, ethnic concentration, material deprivation and dependency, an indicator of age and labour force) with harsh parenting practices and inter-partner conflict during the early lockdown of the COVID-19 pandemic in Ontario, Canada., Design: A cross-sectional analysis of data from the Ontario Parent Survey., Setting: A convenience sample of 7451 caregivers living in Ontario, Canada, at the time of baseline data collection (May-June 2020)., Participants: Caregivers aged 18 years and older with children 17 years or younger., Outcome Measures: Parenting practices over the past 2 months was assessed using a published modification of the Parenting Scale. The frequency of inter-partner conflict over the past month was assessed using the Marital Conflict scale., Results: Individual (sociodemographic factors, alcohol use, and higher depressive and anxiety symptoms) and family (difficulties with managing the household and child mood and behaviour) level factors were positively associated with inter-partner conflict and harsh parenting practices. Having fewer positive experiences (eg, performing activities with children), and economic adversity at the family level were positively associated with inter-partner conflict but inversely associated with harsh parenting. At the community level, residential instability was negatively associated with harsh parenting practices., Conclusions: Individual and family level factors were associated with harsh parenting and inter-partner conflict. The associations of fewer positive experiences and economic hardship with harsh parenting practices may be more complex than initially thought. Efforts that raise awareness and address caregiver mental health concerns are needed as part of the pandemic response to promote positive inter-partner and parent-child interactions., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

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.

Objectives: In this review we: (1) identify and describe nationally representative surveys with child maltreatment (CM) questions conducted by governments in low-income, middle-income and high-income countries and (2) describe procedures implemented to address respondents' safety and minimise potential distress., Design: We conducted a systematic search across eight databases from 1 January 2000 to 5 July 2021 to identify original studies with information about relevant surveys. Additional information about surveys was obtained through survey methods studies, survey reports, survey websites or by identifying full questionnaires (when available)., Results: Forty-six studies representing 139 surveys (98 youth and 41 adult) conducted by governments from 105 countries were identified. Surveys implemented a variety of procedures to maximise the safety and/or reduce distress for respondents including providing the option to withdraw from the survey and/or securing confidentiality and privacy for the respondent. In many surveys, further steps were taken such as providing information for support services, providing sensitivity training to survey administrators when interviews were conducted, among others. A minority of surveys took additional steps to empirically assess potential distress experienced by respondents., Conclusions: Assessing risk and protective factors and developing effective interventions and policies are essential to reduce the burden of violence against children. While asking about experiences of CM requires careful consideration, procedures to maximise the safety and minimise potential distress to respondents have been successfully implemented globally, although practices differ across surveys. Further analysis is required to assist governments to implement the best possible safety protocols to protect respondents in future surveys., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

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.

Background: Children of girls and young women experiencing socioeconomic disadvantage are at risk of maltreatment and associated health and developmental problems. Nurse-Family Partnership (NFP) is an early intervention program designed to improve child and maternal health outcomes. The effectiveness of NFP is being evaluated in British Columbia (BC) through a randomized controlled trial, augmented by a process evaluation to identify influences on how NFP was implemented., Objective: To describe how public health nurses providing NFP perceived their interactions with child protection professionals., Participants and Setting: Forty-seven public health nurses across BC., Methods: The principles of interpretive description informed the qualitative component of the process evaluation. Data from interviews and focus groups were analyzed using the framework analysis approach. A thematic framework was generated through processes of coding, charting and mapping, with a focus on organizational and systems influences., Results: Nurses' practice in supporting families often involved engagement with child protection services. Four themes about the nature of this work were identified: 1) developing a deeper understanding of the disciplinary perspectives of child protection, 2) striving for strengthened collaboration, 3) navigating change and uncertainty, and 4) responding to family and community complexity., Conclusions: Participants valued the contribution of child protection professionals and expressed willingness to collaborate to support families. However, collaboration was constrained by multiple structural barriers. Collaborative models offer possibilities for integrated practice, although can be difficult to implement within current health and child protection systems and child protection regulatory contexts., (Copyright © 2021 Elsevier Ltd.

Background: Vaping among adolescents and young adults is a significant public health concern worldwide. Understanding which risk factors are associated with vaping is important to help inform evidence-based prevention and intervention strategies. There are several gaps in the current literature examining these associations such as limited longitudinal research. We examined the association between parental smoking/vaping, adolescent sex, mental disorders in adolescence, 13 adverse childhood experiences (ACEs) and a) any vaping and b) course of vaping across two time points among adolescents and young adults., Methods: Data were from Waves 1 and 2 of the longitudinal Well-Being and Experiences Study (The WE Study) in Manitoba, Canada which collected data from a community sample of adolescents (14 to 17 years) and their parent/caregiver in Wave 1 in 2017-18 and the adolescents/young adults only in Wave 2 in 2019. A total of 752 adolescents/young adults (72.4% of the original cohort) completed both waves of the study. Binary and multinomial logistic regressions were conducted to understand the relationship between the 16 risk factors and the two vaping outcomes., Results: Vaping prevalence was 45.5% for any vaping, 2.7% for Wave 1 vaping only, 19.7% for new onset Wave 2 vaping, and 21.2% for vaping at both waves. After adjusting for covariates, the majority of risk factors examined were associated with any adolescent or young adult vaping, including: parental smoking or vaping, emotional abuse, emotional neglect, exposure to verbal intimate partner violence, household substance use, household mental illness, parental separation/divorce, parental problems with police, foster care or contact with a child protective organization, an unsafe neighbourhood, and peer victimization. The majority of these risk factors, as well as adolescent mental health and parental gambling, were associated with different courses of vaping across the two time points., Conclusions: The findings emphasize the need for early vaping prevention and identified several ACEs and other factors that were associated with adolescent and young adult vaping and course of vaping. These identified ACEs and risk factors can help inform programs, strategies, and potential groups to target for vaping interventions., (© 2022. The Author(s).)

Epidemiological surveys measuring the prevalence of child maltreatment generate essential knowledge that is required to enhance human rights, promote gender equality, and reduce child abuse and neglect and its effects. Yet, evidence suggests Institutional Review Boards (IRBs) may assess the risk of these studies using higher than normal thresholds, based on a perception they may cause high distress to participants. It is essential for IRBs and researchers to have an accurate understanding of the nature and extent of participant distress associated with these studies, and of the duties of researchers towards survey participants, so that meritorious research is endorsed and duties to participants discharged. Assessment by IRBs of the ethics of such research must be appropriately informed by scientific evidence, ethical principles, and legal requirements. This article adds to knowledge by considering participant distress in child maltreatment surveys and its appropriate ethical and operational treatment. We provide an updated overview of scientific evidence of the frequency and severity of distress in studies of child maltreatment, a review of ethical requirements including a focus on beneficence and participant welfare, and a new analysis of researchers' legal duties towards participants. Our analyses demonstrate that participant distress is infrequent and transitory, that researchers can satisfy ethical requirements towards participants, and that legal liability does not extend to emotional distress. Informed by these bodies of knowledge, we distil key principles of good epidemiological practice to provide solutions to operational requirements in these surveys, which both fulfil ethical requirements to participants, and demonstrate trauma-informed practice., (Copyright © 2021 The Authors.

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: In 1996, the ISPCAN Working Group on Child Maltreatment Data (ISPCAN-WGCMD) was established to provide an international forum in which individuals, who deal with child maltreatment data in their respective professional roles, can share concerns and solutions., Objective: This commentary describes some of the key features and the status of child maltreatment related data collection addressed by the ISPCAN-WGCMD., Methods: Different types of data collection methods including self-report, sentinel, and administrative data designs are described as well as how they address different needs for information to help understand child maltreatment and systems of prevention and intervention., Results: While still lacking in many parts of the world, access to child maltreatment data has become much more widespread, and in many places a very sophisticated undertaking., Conclusion: The ISPCAN-WGCMD has been an important forum for supporting the continued development and improvement in the global effort to understand and combat child maltreatment thus contributing to the long term goals of the UN Convention on the Rights of the Child. Nevertheless, based on what has been learned, even greater efforts are required to improve data in order to effectively combat child maltreatment., (Copyright © 2020 Elsevier Ltd.

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.)

The purpose of this analysis was to understand public health nurses' experiences in preventing and addressing suspected child maltreatment within the context of home visiting. The principles of interpretive description guided study decisions and data were generated from interviews with 47 public health nurses. Data were analyzed using reflexive thematic analysis. The findings highlighted that public health nurses have an important role in the primary prevention of child maltreatment. These nurses described a six-step process for managing their duty to report suspected child maltreatment within the context of nurse-client relationships. When indicators of suspected child maltreatment were present, examination of experiential practice revealed that nurses developed reporting processes that maximized child safety, highlighted maternal strengths, and created opportunities to maintain the nurse-client relationship. Even with child protection involvement, public health nurses have a central role in continuing to work with families to develop safe and competent parenting skills., Competing Interests: Declaration of Conflicting Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2021.)

Background: Both childhood maltreatment (CM) and intimate partner violence (IPV) are public health problems that have been related to a wide range of adverse health consequences. However, studies examining associations between specific types of CM and experiencing IPV in adulthood have yielded conflicting results., Methods: Using data from 10,608 men and 11,458 women aged 18 or older from Canada's 2014 General Social Survey, we examined associations between three types of CM-childhood physical abuse (CPA), childhood sexual abuse (CSA), and childhood exposure to IPV -and subsequent intimate partner violence (IPV) in adulthood (physical, sexual or emotional)., Results: When potential confounders were controlled, CPA, CSA and childhood exposure to IPV were associated with IPV in adulthood for both sexes (odds ratios, 1.7, 1.8 and 2.0 for men, and 2.2, 2.0 and 2.1 for women). When severity and frequency of CM were examined, a dose-response relationship between all three types of CM and IPV in adulthood was observed among women (meaning that as the severity/frequency of CM increased, the likelihood of reporting IPV also increased); among men, a dose-response relationship was observed only for CPA., Conclusions: The association between CM and IPV in adulthood is particularly concerning because experiencing multiple forms of trauma has cumulative effects. Lifespan studies have shown that individuals who experience multiple incidents of abuse exhibit the highest levels of impairment. This underscores the importance of programs to eradicate both CM and IPV. This underscores the importance of programs to eradicate both CM and IPV. Future research should focus on assessing interventions designed to promote healthy relationships and the provision of emotional support and coping mechanisms to children and families in abusive situations.

Background: Nurse-Family Partnership (NFP) involves public health nurses providing frequent home visits from early pregnancy until children reach age 2 years, focusing on first-time parents experiencing socioeconomic disadvantage. Our aim was to evaluate NFP's effectiveness in improving child and maternal health., Methods: We conducted an analysis of prenatal secondary outcomes in an ongoing randomized controlled trial in British Columbia; the data used in this analysis were collected from January 2014 to May 2017. Participants were pregnant girls and women aged 14-24 years who were preparing to parent for the first time and experiencing socioeconomic disadvantage. They were randomly allocated 1:1 to the intervention (NFP plus existing services) or control group (existing services). Prespecified prenatal secondary outcome indicators were changes in use of nicotine cigarettes and alcohol use by 34-36-weeks' gestation. We also report on prespecified exploratory cannabis and street drug use measures. We used mixed-effect models for longitudinal and clustered data to estimate intervention effects. Analyses were by intention to treat., Results: The median gestational age at baseline for the 739 participants (368 participants in the intervention group, 371 in the comparison group) was 20 weeks, 6 days. By 34-36 weeks' gestation, NFP significantly reduced cigarette counts (over the past 2 d) (difference in changes [DIC] of count -1.6, 95% confidence interval [CI] -6.4 to -1.3) in those who smoked. NFP also significantly reduced rates of prenatal cannabis use (DIC -6.4, 95% CI -17.0 to -1.7), but not rates of street drug or "any" substance use. While we observed decreased rates of cigarette and alcohol use in both groups (DIC of proportions -2.8, 95% CI -15.3 to 0.6; DIC -0.5, 95% CI -8.7 to 1.8, respectively), these changes were not statistically significant., Interpretation: We found no evidence that NFP was effective in reducing rates of prenatal cigarette and alcohol use; however, it led to reduced prenatal cannabis use, and in smokers it led to modest reductions in cigarette use. NFP may therefore hold promise for reducing some types of prenatal substance use in disadvantaged populations. Trial registration: ClinicalTrials.gov, no.
