Child Abuse Negl 2023 106493 BACKGROUND: Adverse Childhood Experiences (ACEs) are associated with poor mental health outcomes and risk-taking behaviors. Positive childhood experiences (PCEs) may mitigate these negative impacts. OBJECTIVE: This study 1) assessed the associations between ACEs and negative health outcomes and risk-taking behaviors among young adults, and 2) evaluated whether - and which - PCEs moderate the association between ACEs and these outcomes in sub-Saharan Africa. METHODS: This multi-country analysis combined cross-sectional representative survey data from young adults, ages 18-24 years, from the 2019 Kenya, 2018 Lesotho, 2019 Mozambique, and 2019 Namibia Violence Against Children and Youth Surveys. The association between experiencing any ACEs and each health outcome was assessed using Wald's chi-square tests. Multivariable logistic regression analyses assessed the association between each PCE and each outcome of interest. RESULTS: Females who experienced any ACEs had higher odds of experiencing moderate to severe mental distress (aOR = 2.7, 95%CI: 1.9, 3.9). Males who experienced any ACEs had higher odds of experiencing suicidal/self-harm behaviors (aOR = 6.7, 95%CI: 2.8, 16.0) and substance use (aOR = 2.5, 95%CI: 1.4, 4.2). In females, strong mother-child relationship was protective against moderate to severe mental distress (aOR = 0.7, 95%CI: 0.6, 0.9), suicidal/self-harm behaviors (aOR = 0.6, 95%CI: 0.4, 0.9), and substance use (aOR = 0.6, 95%CI: 0.4, 0.9). For males, a strong mother-child relationship was protective against suicidal/self-harm behaviors (aOR = 0.5, 95%CI: 0.2, 0.9), and a strong father-child relationship was protective against suicidal/self-harm behaviors (aOR = 0.4, 95%CI: 0.2, 0.7) and substance use (aOR = 0.6, 95%CI: 0.4, 0.8). CONCLUSIONS: Strong parenting programs may likely play an important role in improving the psychosocial health of young adults. |
A comparison of two population-based household surveys in Uganda for assessment of violence against youth
Currie DW , Apondi R , West CA , Biraro S , Wasula LN , Patel P , Hegle J , Howard A , Benevides de Barros R , Durant T , Chiang LF , Voetsch AC , Massetti GM . PLoS One 2021 16 (12) e0260986 Violence is associated with health-risk behaviors, potentially contributing to gender-related HIV incidence disparities in sub-Saharan Africa. Previous research has demonstrated that violence, gender, and HIV are linked via complex mechanisms that may be direct, such as through forced sex, or indirect, such as an inability to negotiate safe sex. Accurately estimating violence prevalence and its association with HIV is critical in monitoring programmatic efforts to reduce both violence and HIV. We compared prevalence estimates of violence in youth aged 15-24 years from two Ugandan population-based cross-sectional household surveys (Uganda Violence Against Children Survey 2015 [VACS] and Uganda Population-based HIV Impact Assessment 2016-2017 [UPHIA]), stratified by gender. UPHIA violence estimates were consistently lower than VACS estimates, including lifetime physical violence, recent intimate partner physical violence, and lifetime sexual violence, likely reflecting underestimation of violence in UPHIA. Multiple factors likely contributed to these differences, including the survey objectives, interviewer training, and questionnaire structure. VACS may be better suited to estimate distal determinants of HIV acquisition for youth (including experience of violence) than UPHIA, which is crucial for monitoring progress toward HIV epidemic control. |
The relationship between commercial sexual exploitation of children (CSEC) and childhood sexual abuse (CSA) among boys and girls in Haiti
Silverman JG , Boyce SC , Fonseka RW , Triplett D , Chiang LF , Caslin SS , Raj A . Int J Inj Contr Saf Promot 2021 29 (1) 1-7 To test the hypothesis that childhood sexual abuse (CSA) is a risk factor for commercial sexual exploitation of children (CSEC), we analysed data from the Haiti Violence Against Children Survey (VACS), a population-based sample of adolescents and young adults ages 13-24 (1459 males and 1457 females). Twenty-one percent of males and 25% of females reported CSA; 6% of males and 4% of females reported CSEC. The adjusted odds ratios (AORs) for CSEC based on exposure to CSA were 5.6 (95% confidence interval/CI: 3.1-10.2) for males and 5.9 (CI: 2.6-13.0) for females. For each year earlier that males first experienced CSA, the odds of CSEC increased 60% (AOR 1.6, CI 1.2-2.0). In this first nationally-representative study of lifetime CSEC, both boys and girls victimised by CSA in Haiti were more likely to have also experienced CSEC than other youth, with children who experienced CSA at younger ages at the greatest risk. |
Changes in prevalence of violence and risk factors for violence and HIV among children and young people in Kenya: a comparison of the 2010 and 2019 Kenya Violence Against Children and Youth Surveys
Annor FB , Chiang LF , Oluoch PR , Mang'oli V , Mogaka M , Mwangi M , Ngunjiri A , Obare F , Achia T , Patel P , Massetti GM , Dahlberg LL , Simon TR , Mercy JA . Lancet Glob Health 2021 10 (1) e124-e133 BACKGROUND: Previous research has shown a high prevalence of violence among young people in Kenya. Violence is a known risk factor for HIV acquisition and these two public health issues could be viewed as a syndemic. In 2010, Kenya became the third country to implement the Violence Against Children and Youth Survey (VACS). The study found a high prevalence of violence in the country. Led by the Government of Kenya, stakeholders implemented several prevention and response strategies to reduce violence. In 2019, Kenya implemented a second VACS. This study examines the changes in violence and risk factors for violence and HIV between 2010 and 2019. METHODS: The 2010 and 2019 VACS used a similar sampling approach and measures. Both VACS were cross-sectional national household surveys of young people aged 13-24 years, designed to produce national estimates of physical, sexual, and emotional violence. Prevalence and changes in lifetime experiences of violence and risk factors for violence and HIV were estimated. The VACS uses a three-stage cluster sampling approach with random selection of enumeration areas as the first stage, households as the second stage, and an eligible participant from the selected household as the third stage. The VACS questionnaire contains sections on demographics, risk and protective factors, violence victimisation, violence perpetration, sexual behaviour, HIV testing and services, violence service knowledge and uptake, and health outcomes. For this study, the main outcome variables were violence victimisation, context of violence, and risk factors for violence. All analyses were done with the entire sample of 13-24-year-olds stratified by sex and survey year. FINDINGS: The prevalence of lifetime sexual, physical, and emotional violence significantly declined in 2019 compared with 2010, including unwanted sexual touching, for both females and males. Experience of pressured and forced sex among females also decreased between the surveys. Additionally, significantly more females sought and received services for sexual violence and significantly more males knew of a place to seek help in 2019 than in 2010. The prevalence of several risk factors for violence and HIV also declined, including infrequent condom use, endorsement of inequitable gender norms, endorsement of norms justifying wife beating, and never testing for HIV. INTERPRETATION: Kenya observed significant declines in the prevalence of lifetime violence and some risk factors for violence and HIV, and improvements in some service seeking indicators between 2010 and 2019. Continued prioritisation of preventing and responding to violence in Kenya could contribute to further reductions in violence and its negative outcomes. Other countries in the region that have made substantial investments and implemented similar violence prevention programmes could use repeat VACS data to monitor violence and related outcomes over time. FUNDING: None. |
Violence Against Children Surveys (VACS): towards a global surveillance system
Chiang LF , Kress H , Sumner SA , Gleckel J , Kawemama P , Gordon RN . Inj Prev 2016 22 Suppl 1 i17-i22 OBJECTIVE: To describe the Violence Against Children Surveys (VACS). The survey is a national, household survey that systematically measures the prevalence, nature and consequences of sexual, physical and emotional violence against children. DESIGN: This report provides information about the history, implementation, ethical protections, utility, results, limitations, and future directions of the VACS work. RESULTS: The study has been implemented in 11 countries in Africa, Asia and the Caribbean, providing each of these countries with baseline data and momentum to address violence against children as a public health and human rights priority. These data are novel in each country, and VACS is well poised to contribute to an existing surveillance system or be used as the basis of a periodic surveillance system. CONCLUSIONS: Without ongoing surveillance to assess prevalence and the impact of policy, prevention and response programming, violence will likely continue to be overlooked as the linchpin public health crisis that it is, globally and in individual countries. |
Sexual violence against female and male children in the United Republic of Tanzania
Vagi KJ , Brookmeyer KA , Gladden RM , Chiang LF , Brooks A , Nyunt MZ , Kwesigabo G , Mercy JA , Dahlberg LL . Violence Against Women 2016 22 (14) 1788-1807 During a household survey in Tanzania, a nationally representative sample of females and males aged 13-24 years reported any experiences of sexual violence that occurred before the age of 18 years. The authors explore the prevalence, circumstances, and health outcomes associated with childhood sexual violence. The results suggest that violence against children in Tanzania is pervasive, with roughly three in 10 females and one in eight males experiencing some form of childhood sexual violence, and its health consequences are severe. Results are being used by the Tanzanian government to implement a National Plan of Action. |
HIV and childhood sexual violence: implications for sexual risk behaviors and HIV testing in Tanzania
Chiang LF , Chen J , Gladden MR , Mercy JA , Kwesigabo G , Mrisho F , Dahlberg LL , Vagi K , Brookmeyer KA . AIDS Educ Prev 2015 27 (5) 474-87 Prior research has established an association between sexual violence and HIV. Exposure to sexual violence during childhood can profoundly impact brain architecture and stress regulatory response. As a result, individuals who have experienced such trauma may engage in sexual risk-taking behavior and could benefit from targeted interventions. In 2009, nationally representative data were collected on violence against children in Tanzania from 13-24 year old respondents (n = 3,739). Analyses show that females aged 19-24 (n = 579) who experienced childhood sexual violence, were more likely to report no/infrequent condom use in the past 12 months (AOR = 3.0, CI [1.5, 6.1], p = 0.0017) and multiple sex partners in the past 12 months (AOR = 2.3, CI [1.0, 5.1], p = 0.0491), but no more likely to know where to get HIV testing or to have ever been tested. Victims of childhood sexual violence could benefit from targeted interventions to mitigate impacts of violence and prevent HIV. |
