Sexual abuse and post-traumatic stress disorder in childhood, adolescence and young adulthood: a systematic review and meta-analysis

Violence Against Children, Self-Harm, and Suicidal Behaviors: A Pooled and Country-Specific Analysis of Eight Low- and Middle-Income Countries

PURPOSE

This study assessed associations between experiences of physical or sexual violence in childhood and self-harm, suicidal ideation, and suicide attempts among young people in low- and middle-income countries (LMICs) and whether these associations varied by sex and perpetrator identity.

METHODS

We used nationally representative data from the Violence Against Children and Youth Surveys in eight LMICs (2017-2019). The analytic sample included 33,381 young men and women (ages 13-24 years). Multivariable logistic regressions with country-fixed effects were used to estimate the associations between childhood physical and sexual violence and the three outcomes. Stratified analyses were performed by country, participant's sex, and type of perpetrator (parent/caregiver, other adults, peers, and intimate partner).

RESULTS

About 40% of the participants reported physical childhood violence, and 10% experienced childhood sexual violence. Childhood violence was associated with increased odds of self-harm (physical violence: adjusted odds ratio [aOR]: 2.2, 95% confidence interval [CI]: 2.0-2.4; sexual violence: aOR: 2.7, 95%, CI: 2.3-3.0), suicidal ideation (physical: aOR: 3.0, 95% CI: 2.7-3.3; sexual: aOR: 4.0, 95%, CI: 3.6-4.5), and suicide attempts (physical: aOR: 3.6, 95% CI: 3.2-4.1; sexual: aOR: 4.9, 95%, CI: 4.3-5.7). Consistent findings were observed in country-specific analyses. The odds of all outcomes were highest among those who experienced childhood physical violence by intimate partners and childhood sexual violence by parents or caregivers. Young women who experienced childhood sexual violence had higher odds for all outcomes than young men.

DISCUSSION

Violence prevention and mental health programs for young people in LMICs should consider the types of violence experienced, the perpetrator, and the sex of the survivor.

Burden of Mental Disorders and Suicide Attributable to Childhood Maltreatment

Importance

The proportion of mental disorders and burden causally attributable to childhood maltreatment is unknown.

Objective

To determine the contribution of child maltreatment to mental health conditions in Australia, accounting for genetic and environmental confounding.

Design, Setting, and Participants

This meta-analysis involved an epidemiological assessment accounting for genetic and environmental confounding between maltreatment and mental health and 3 cross-sectional national surveys: the Australian Child Maltreatment Study (ACMS) 2023, National Study of Mental Health and Well-being 2020-2022, and Australian Burden of Disease Study 2023. Causal estimates were derived on the association between childhood maltreatment and mental health conditions from a meta-analysis of quasi-experimental studies. This was combined with the prevalence of maltreatment from the ACMS to calculate the population attributable fraction (PAF). The PAF was applied to the number and burden of mental health conditions in Australia, sourced from 2 population-based, nationally representative surveys of Australians aged 16 to 85 years, to generate the number and associated burden of mental disorders attributable to child maltreatment.

Exposure

Physical abuse, sexual abuse, emotional abuse, or neglect prior to age 18 years.

Main Outcomes and Measures

Proportion and number of cases, years of life lost, years lived with disability, and disability-adjusted life-years of mental health conditions (anxiety, depression, harmful alcohol and drug use, self-harm, and suicide attempt) attributable to childhood maltreatment.

Results

Meta-analytic estimates were generated from 34 studies and 54 646 participants and applied to prevalence estimates of childhood maltreatment generated from 8503 Australians. Childhood maltreatment accounted for a substantial proportion of mental health conditions, ranging from 21% (95% CI, 13%-28%) for depression to 41% (95% CI, 27%-54%) of suicide attempts. More than 1.8 million cases of depressive, anxiety, and substance use disorders could be prevented if childhood maltreatment was eradicated. Maltreatment accounted for 66 143 years of life lost (95% CI, 43 313-87 314), primarily through suicide, and 184 636 disability-adjusted life-years (95% CI, 109 321-252 887).

Conclusions and Relevance

This study provides the first estimates of the causal contribution of child maltreatment to mental health in Australia. Results highlight the urgency of preventing child maltreatment to reduce the population prevalence and burden of mental disorders.

Gender Differences in the Characterization of Child Sexual Abuse

Research on child sexual abuse (CSA) has increased in recent decades. However, the study of gender differences in this field is still scarce. The aim of this study was to analyze the differences in the characterization of CSA between Spanish adult men and women. The Juvenile Victimization Questionnaire was administered to 162 cisgender victims of CSA aged 18-63. Most of the abuses involved physical contact and were committed by a known person. Twenty percent of the victims indicated that they had developed a mental health problem that they believed was due to the CSA experience. Women suffered more CSA with physical contact and penetration, more types of abuse and more abuse by men, and were abused more frequently by a family member. Compared to women, men suffered more sexual abuse by women. Exploring gender differences in CSA could help to improve preventive strategies and interventions aimed at reducing the occurrence of this type of abuse and sequelae resulting from it.

What are the predictive variables that increase the risk of developing a complex trauma? A meta-analysis

In 2018, Complex Post Traumatic Stress Disorder (CPTSD) was officially recognized as a distinct syndrome in the International Classification of Diseases, 11th Revision (ICD-11). This recognition aimed to differentiate between neurotic disorders secondary to stressful situations and somatoform disorders, and disorders specifically associated with stress. The inclusion of CPTSD in the ICD-11 marked the culmination of two decades of research focused on understanding its symptoms, treatments, and risk factors. However, despite the progress made, a comprehensive meta-analysis to elucidate the specific risk factors and impact on the development of CPTSD is still lacking. The objective of this article is to conduct such a meta-analysis. A total of 24 studies were selected for analysis, and the findings revealed several key risk factors associated with the development of CPTSD. The main risk factor identified is having experienced sexual abuse in childhood (k = 12; OR = 2.880). In addition, childhood physical abuse (k = 11; OR = 2.841), experiencing emotional neglect during childhood (k = 5; OR = 2.510), physical abuse throughout life (k = 8; OR = 2.149) and being a woman (k = 13; OR = 1.726) were also significant risk factors.

Childhood Sexual Abuse and Relationship Satisfaction: The Moderating Role of PTSD and Sexual-Related Posttraumatic Stress Symptoms

Research on childhood sexual abuse (CSA) has consistently demonstrated the long-term effects of such abuse, not only on survivors' development, but also on the nature and quality of their adult relationships, particularly romantic ones. In this study we examined the moderating role of posttraumatic stress disorder (PTSD) and sexual-related posttraumatic stress symptoms (sexual-related PTSS) between CSA and relationship satisfaction. Survey data from 529 individuals who reported being currently in a romantic relationship were analyzed. In the first set of analyses, results demonstrated that participants with CSA reported significantly lower relationship satisfaction and significantly greater severity of PTSD and sexual-related PTSS than participants without CSA. Sexual-related PTSS but not PTSD moderated the association between CSA and participants' relationship satisfaction, with the model of sexual-related PTSS explaining 20.8% of the variance in relationship satisfaction and the model of PTSD explaining 11.3% of this variance. In the second set of analyses conducted among survivors of CSA only, higher sexual-related PTSS severity was linked with ongoing abuse and with abuse by a non-family member. This study points to the potential contribution made by sexual-related PTSS to relationship satisfaction among survivors of CSA.

Reconsidering the Unwanted Sexual Touching of Boys by Adults: An Ethnographic Study in Rural Cambodia

The unwanted sexual touching of boys by adults is a form of child sexual abuse. However, the genital touching of boys may be culturally "normal," with not all instances necessarily being "unwanted" or "sexual." This study, set in Cambodia, explored the genital touching of boys and the local cultural constructions of it. It entailed ethnography, participant observation, and case studies involving 60 parents, family members, caregivers, and neighbors (18 men, 42 women) in 7 rural provinces and Phnom Penh. Informants' views, along with their use of language, proverbs, sayings, and folklore were recorded. The combination of the emotional driver for touching a boy's genitals and the physical action of doing so is /krɨɨt/ (គ្រឺត or ក្រឺត). The motivation is usually overwhelming affection, and to socialize the boy to cover his nakedness in public. The spectrum of action ranges from light touching to grabbing and pulling. Benign and non-sexual intention is signaled by adding the Khmer predicative /tʰoammeaʔtaa/, or "normal," as an adverb to the attributive verb /leiŋ/, or play. The genital touching of boys by parents and caregivers is not necessarily sexual in nature, though it is possible that abuse can be committed despite the absence of such intention. Cultural insights are not a "defense" or basis for exculpation, with each case evaluated simultaneously through cultural and rights-based lenses. There are anthropological implications in gender studies, and it is essential to have an understanding of the concept of /krɨɨt/ to ensure that interventions to protect the rights of children are culturally responsive.
