An estimated 840 million women and adolescents globally have experienced physical or sexual partner violence, non-partner sexual violence, or both during their lifetimes, according to World Health Organization data. In Chile, a population-based study published in The Lancet Regional Health Americas reveals that childhood sexual abuse acts as a critical common denominator underlying three distinct forms of adult sexual victimization.
In Plain English: The Clinical Takeaway
- Multilevel epidemiological analysis: Researchers examined population-wide survey data from 13,128 urban women aged 15 and older to evaluate social determinants of gender-based violence.
- Shared risk factor: A history of childhood sexual abuse more than doubles the statistical probability of experiencing intimate partner sexual violence, third-party sexual assault, and third-party sexual harassment later in life.
- Public health integration: Findings indicate that healthcare systems must adopt trauma-informed care and bridge child protection services with adult mental health infrastructure.
Epidemiological Findings on Sexual Victimization in Chile
The study, titled “Social determinants of partner and non-partner sexual violence against women in Chile: a population-based multilevel analysis,” was led by Francisca Crispi during her doctoral research in Public Health at the University of Chile. Collaborating researchers included Alejandra Fuentes-García from the University of Chile’s School of Public Health and Nicolás Libuy from the Adolfo Ibáñez University School of Government. The team analyzed the 2017 and 2020 rounds of Chile’s National Survey on Intrafamily Violence and Violence in Other Spaces, incorporating a pooled sample of 13,128 women aged 15 or older residing in urban areas.
The data demonstrated that over the 12 months prior to the surveys, 2.8% of respondents experienced intimate partner sexual violence, 2.5% suffered third-party sexual assault involving physical contact, and 11.3% encountered non-contact third-party sexual harassment such as verbal insinuations, intimidation, and conditional benefits. According to Francisca Crispi, “The data of these surveys show that still, annually, we have a victimization that goes from 3% to 11%, depending on the type of sexual violence that we measure.”
Statistical Impact of Childhood Sexual Abuse on Adult Risk
While the researchers emphasize the necessity of distinguishing between intimate partner sexual violence, third-party sexual assault, and third-party sexual harassment for targeted prevention, they identified childhood sexual abuse as a shared precursor across all three categories. Women reporting a history of childhood sexual abuse exhibited significantly elevated adjusted odds ratios (OR) for subsequent victimization.
| Form of Sexual Violence | Adjusted Odds Ratio (OR) vs. No Childhood Abuse | 12-Month Prevalence (%) |
|---|---|---|
| Intimate Partner Sexual Violence | 2.05 | 2.8% |
| Third-Party Sexual Assault | 3.03 | 2.5% |
| Third-Party Sexual Harassment | 2.06 | 11.3% |
Alejandra Fuentes-García noted the policy implications of these statistics, stating that communities must remain highly alert to childhood sexual abuse and its prevention. Fuentes-García highlighted the need to determine “how can we have an attention informed by the trauma and how then can the response be articulated between child protection systems, health systems, and mental health.”
Additional Social Determinants and Environmental Vulnerabilities
Beyond childhood trauma, the researchers identified distinct social and environmental pathways influencing victimization risk. Francisca Crispi observed that having a partner who experienced violence in childhood or displays violent behavior in other spheres multiplies a woman’s risk of victimization. This pattern provides public health frameworks an entry point to identify relational domination and offer early preventative support.
Vulnerability profiles vary by demographics and geography. Alejandra Fuentes-García noted that acute vulnerabilities to third-party sexual violence concentrate among younger women and residents of the Santiago Metropolitan Region. Meanwhile, non-contact sexual harassment exhibits a distinct operational pattern. Crispi explained that harassment by non-partners affects women who are more exposed through frequent utilization of public spaces, higher education, or employment, highlighting the necessity for environmental safety interventions in public infrastructure rather than placing the burden of avoidance on potential victims.
