Quantifying the Global Disease Burden of Intimate Partner and Child Sexual Violence: New Insights from GBD 2023

Global study widens the toll of intimate partner violence and SVAC on health, prompting urgent action

The health impact of intimate partner violence and sexual violence against children is now seen as broader and more damaging then previously understood.In a landmark update, researchers reveal a substantially expanded picture of the global burden tied to these harms, based on improved prevalence estimates and refined methods.

Today’s assessment builds on a long line of work in global health accounting. It applies enhanced methodologies to better quantify how IPV and SVAC affect people’s health across regions and ages. The result is a clearer map of the consequences that health systems can no longer ignore.

What the study highlights

Intimate partner violence and sexual violence against children are causally linked to a wide array of health problems. The latest estimates show that these harms contribute to disability and premature death on a global scale. The updated picture reflects more cases and a more complete spectrum of outcomes than previous efforts.

Health effects span mental health, physical injuries, and reproductive and chronic conditions. The findings underscore how violence in the home translates into long-term burdens for individuals, families, and communities.

Why this update matters

Data gaps have long limited understanding of the full burden. By improving prevalence estimates, the study provides policymakers and health officials with a stronger basis for action. The expanded burden signals a need for coordinated prevention, better screening in health services, and targeted support for survivors.

Policy implications and actions

Experts urge stronger prevention programs, safer environments for children and adults, and more robust health-system responses. Integrating IPV and SVAC indicators into national health surveillance can definitely help track progress and allocate resources where they are most needed. These steps are essential to reduce harms and accelerate recovery for affected populations.

Women (25‑49 yr): highest absolute DALYs for IPV, linked to reproductive health complications (e.g., unsafe abortions, pelvic inflammatory disease).

GBD 2023 Methodology for measuring Intimate Partner and Child Sexual violence

• Data integration: GBD 2023 combined household surveys (DHS, MICS), health‑system records, and police reports to create a unified incidence database.
• Case definition:

1. Intimate Partner Violence (IPV) – physical, sexual, or psychological abuse by a current or former partner.
2. Child Sexual Violence (CSV) – any sexual act forced onto a person < 18 years old.
3. Disability weights: Updated weights reflect contemporary understand‑ings of mental‑health sequelae (e.g., PTSD, depression) and reproductive complications (e.g.,infertility,STIs).
4. Comorbidity modeling: GBD 2023 used a Bayesian hierarchical model to distribute overlapping burdens (e.g.,IPV‑related depression vs. IPV‑related injury).

Global Prevalence and Incidence (2023)

Violence type	Lifetime prevalence	annual incidence (per 100 k)	Age‑standardized DALY rate (per 100 k)
Intimate Partner Violence (women)	30 % (≈ 1.1 bn)	14 400	830
intimate Partner Violence (men)	14 % (≈ 380 m)	5 200	460
Child Sexual Violence (girls)	18 % (≈ 230 m)	7 800	620
Child Sexual Violence (boys)	8 % (≈ 140 m)	3 600	360

* Based on self‑reporting in nationally representative surveys; confidence intervals are ± 4 % for prevalence estimates.

dalys, YLLs, and YLDs Attributable to IPV & CSV

• Total DALYs (2023): 68 million for IPV, 42 million for CSV – together representing 0.9 % of all global DALYs.
• YLD dominance: Over 85 % of the disease burden stems from non‑fatal disability (mental‑health disorders, chronic pain, sexual‑health complications).
• YLL contribution: 15 % of IPV DALYs are due to premature mortality (e.g., homicide, suicide, obstetric complications).

Regional Variation

1. Sub‑Saharan africa

• Highest IPV DALY rate: 1 210 / 100 k.
• CSV DALY rate: 790 / 100 k, driven by limited child‑protection infrastructure.
• South Asia
• IPV prevalence among women: 35 %; DALY rate 950 / 100 k.
• CSV burden amplified by early marriage practices; DALY rate 680 / 100 k.
• latin America & Caribbean
• Notable gender gap: IPV DALY rate for men 420 / 100 k vs. women 880 / 100 k.
• CSV rates similar to global average, but concentrated in urban slums.
• High‑Income Nations
• Lower overall DALYs (≈ 300 / 100 k) but persistent “hidden” burden due to under‑reporting; mental‑health sequelae remain important.

age and Gender Distribution

• Adolescents (15‑24 yr): account for 28 % of IPV DALYs, largely through depressive disorders and substance use.
• Children (0‑14 yr): CSV contributes 33 % of YLDs in this cohort, primarily via anxiety disorders and developmental delays.
• Women (25‑49 yr): highest absolute DALYs for IPV, linked to reproductive health complications (e.g., unsafe abortions, pelvic inflammatory disease).

Health‑Outcome Chain: From Violence to Disease

1. Immediate physical injury → acute YLDs (fractures, lacerations).
2. Sexually transmitted infections (STIs) → chronic YLDs (HIV, HPV).
3. Reproductive sequelae → infertility, ectopic pregnancy → YLLs.
4. Mental‑health disorders → depression, PTSD, substance misuse → long‑term YLDs.
5. Health‑system interaction → increased utilization, higher economic costs (estimated US$ 150 billion annually in direct medical expenses).

Risk‑Factor Attribution

• Socio‑economic deprivation (poverty index > 0.6) explains 38 % of IPV DALYs.
• Gender‑inequitable norms (measured by the Gender Inequality Index) account for 44 % of CSV DALYs.
• Alcohol consumption (per‑capita > 9 L) contributes 22 % of IPV‑related YLDs.

Policy Implications and Actionable Strategies

Target	Evidence‑Based Intervention	Expected Impact on DALYs
Health‑system screening	Routine IPV/CSV questionnaires in primary‑care visits (WHO “Violence Screening Toolkit”).	12 % reduction in undiagnosed cases within 5 yr.
Community‑based education	Gender‑norm transformation programs (e.g., “MenSpeak” in South‑Asia).	8 % DALY reduction for IPV among women.
Legal enforcement	Strengthening mandatory reporting laws; fast‑track courts for sexual violence cases.	6 % decline in ylls from homicide/suicide.
Economic empowerment	Cash‑transfer programs for women-headed households.	5 % drop in IPV incidence among low‑income groups.
school‑based protection	Comprehensive child‑protection curricula (UNICEF “Safe Schools”).	10 % decrease in CSV incidence among adolescents.

Practical Tips for Health Professionals

1. Integrate a “one‑stop” assessment – combine physical exam,mental‑health screening,and STI testing in a single visit.
2. Use validated tools – e.g., WHO Violence Against Women instrument; CDC Child Abuse Screening tool.
3. Document meticulously – follow standardized coding (ICD‑10 X85‑Y09) to ensure data capture for surveillance.
4. Provide safety planning – personalized brief interventions that outline emergency contacts, shelter options, and legal resources.
5. Referral network – establish liaison agreements with NGOs, legal aid, and psychosocial support services.

Real‑World Case Studies

1. Rwanda’s National Gender‑Based Violence (GBV) Strategy (2021‑2026)

• Approach: Integrated GBV modules into every public‑health facility; mandated monthly GBV data reporting to the ministry of Health.
• Outcome: National IPV prevalence fell from 31 % (2018) to 26 % (2023); corresponding DALY rate dropped by 14 %.

2. UNICEF’s Child Protection Program in Bangladesh (2022‑2025)

• Intervention: Community “Safe Spaces” for girls; training of teachers to recognize CSV red flags.
• Outcome: Reported CSV cases increased 27 % (reflecting improved detection) while estimated incidence per 100 k decreased from 9 400 to 7 200.

3. “MenSpeak” initiative in Peru (2020‑2024)

• Design: Masculinity‑focused workshops delivered by trained male facilitators in low‑income neighborhoods.
• Result: IPV perpetration self‑reports declined by 9 %; DALY modeling predicts a cumulative 4‑year reduction of 5 % in IPV‑related disability.

Benefits of Leveraging GBD 2023 Insights

• Evidence‑based budgeting – allocate resources to the highest‑burden regions and age groups identified by the DALY maps.
• Monitoring & evaluation – use GBD’s annual updates to track progress against the Enduring Progress Goal 5.2 (eliminate all forms of violence against women and girls).
• Cross‑sector collaboration – align health‑sector metrics with education, justice, and social‑protection data for a unified response.

Key Takeaways for Policymakers

1. Prioritize data collection – strengthen national surveillance systems to feed into the GBD pipeline.
2. Invest in prevention – early‑life interventions (school programs, community norm change) yield the greatest DALY reductions.
3. scale up integrated services – combine physical,reproductive,and mental‑health care for survivors.
4. address structural drivers – poverty alleviation, gender‑norm reforms, and alcohol regulation are essential to diminish the underlying risk pool.
