BACKGROUND: Missing and Murdered Indigenous People is a historic and contemporary issue that has gained national attention. In 2021, homicide was the eighth leading cause of death among American Indian/Alaska Native (AIAN) persons aged between 1 and 54 years old, and homicide is the sixth leading cause of death among all AIAN males aged 1-54 years old. AIM: These data will build knowledge around AIAN homicides and to identify circumstances that can aid in comprehensive Missing and Murdered Indigenous People prevention efforts. METHODS: AIAN homicide data came from Centers for Disease Control and Prevention's National Violent Death Reporting System, a state/jurisdiction-based surveillance system that collects detailed information about characteristics and circumstances of violent deaths. We examined data from 2003 to 2020 (all available years) from participating states/jurisdictions. We also assessed sociodemographic characteristics of victims and suspects, incident characteristics and differences across dichotomised urban/rural status. The study was conducted in 2022. RESULTS: The National Violent Death Reporting System provided data on 2959 AIAN homicides from 2003 to 2020 (54.2% urban and 45.8% rural). Significant differences based on the two locations included type of weapon used, the location of the injury, race of the primary suspect, the victim's relationship to the suspect and select circumstances precipitating the homicide including crimes precipitating the homicide and homicides stemming from intimate partner violence. OUTCOMES: These findings provide crucial information to strengthen public health efforts for prevention.

INTRODUCTION: Sexual violence victimization is related to negative impacts, including chronic health conditions. Less is known about possible confounders of this relationship. This study examines the association between lifetime experience of contact sexual violence (CSV) and health conditions by sex, controlling for demographics and other victimization. METHODS: Data are from the 2016/2017 National Intimate Partner and Sexual Violence Survey, a nationally representative study of English- or Spanish-speaking adults. Ten health conditions (e.g., HIV/AIDS) and four activity limitations (e.g., difficulty dressing) were examined related to CSV victimization. Logistic regression models examined the association between CSV victimization and health controlling for demographics and other victimization experiences. Analyses were conducted in 2022-2023. RESULTS: For women and men, many health conditions and activity limitations were significantly associated with CSV after controlling for demographics. Accounting for other victimization, female CSV victims had higher odds of experiencing difficulty sleeping (Adjusted Odds Ratio [AOR]=1.3); difficulty concentrating, remembering, or making decisions (AOR=1.7); and difficulty doing errands alone (AOR=1.4) than non-victims. Male victims had higher odds than non-victims of having HIV/AIDS (AOR=5.2); frequent headaches (AOR=1.5); chronic pain (AOR=1.5); difficulty sleeping (AOR=1.4); serious difficulty hearing (AOR=1.3); and difficulty concentrating, remembering, or making decisions (AOR=1.5). CONCLUSIONS: CSV had a negative impact on health, although other types of victimization appear to also have an impact, especially for women. Demographic characteristics also aid the understanding of the relationship between CSV and health. Efforts to prevent CSV and other forms of violence can be coupled with healthcare- and population-level approaches to improve long-term health.

Abuse of older adults is a public health problem. The National Intimate Partner and Sexual Violence Survey (NISVS) is a nationally-representative, telephone survey for non-institutionalized adults in the United States. To determine the prevalence and factors of intimate partner psychological aggression and physical violence and sexual violence by any perpetrator against older adults, we analyzed NISVS 2016/2017 data (n = 10,171, aged ≥ 60 years). Past 12-month prevalence of psychological aggression, physical violence, and sexual violence was 2.1%, 0.8%, and 1.7%, respectively. Odds of psychological aggression were significantly higher among those with hearing or vision impairment, and lower among those aged ≥70 years. Odds of physical violence were significantly higher for males and for those with hearing or vision impairment. Odds of sexual violence were significantly higher for unpartnered individuals and those with cognitive impairment; and lower for those aged ≥ 70 years. Epidemiologic studies of violence against older adults can inform population-specific prevention strategies.

Homicide is a prevalent cause of death among sex workers, given their increased risk of violence due to proximity to criminal activities such as drug trade and human trafficking. This study analyzes homicide data from the National Violent Death Reporting System (NVDRS) covering 49 US states, the District of Columbia, and Puerto Rico from 2012 to 2020. Case inclusion criteria included: (1) manner of death of homicide, and (2) sex work-related circumstance. Descriptive analyses examined victim and injury characteristics, suspect information, and circumstances. The study identified 321 sex work-related homicides (54% female, 41% male, 6% transgender). Among female victims, 94% were sex workers, and 54% of their suspects were clients. Money conflicts (23%) and other crimes (30%), most often in progress, commonly precipitated homicides of female victims. Substance use problems were reported in 49% of female victims, with 25% of their suspected perpetrators reportedly using substances in the preceding hours. For male victims, 54% were clients and 9% were sex workers. Suspects in male homicides were primarily sex workers (34%) or individuals engaged in sex work-adjacent criminal activities (36%). Money conflicts (49%), other crimes (47%) most often in progress, and sex trafficking involvement (25%) commonly precipitated homicides with male victims. Transgender sex worker victims were mostly transfeminine (94%) and non-Hispanic black (89%). Money conflicts (78%) most commonly precipitated homicides among transgender sex worker victims. These findings can inform prevention strategies addressing underlying risk factors for persons involved in sex work.

INTRODUCTION: Sexual violence is a major public health problem in the United States (U.S.) that is associated with numerous health impacts, including pregnancy. U.S. population-based estimates (2010-2012) found that 3 million women experienced a rape-related pregnancy during their lifetimes. The current study presents more recent estimates of rape and sexual coercion-related pregnancy and examines prevalence by demographic characteristics. METHODS: Data years 2016/2017 were pooled from the National Intimate Partner and Sexual Violence Survey, a random-digit-dial telephone survey of U.S. non-institutionalized adults 18 years and older. The analysis, conducted in 2023, examined lifetime experience of rape-related pregnancy, sexual coercion-related pregnancy, or both among U.S. women. Authors calculated prevalence estimates with 95% confidence intervals and conducted pairwise chi-square tests (p-value < 0.05) to describe experiences by current age, race/ethnicity, and region of residence among U.S. women overall and among victims. RESULTS: One in 20 women in the U.S., or over 5.9 million women, experienced a pregnancy from either rape, sexual coercion, or both during their lifetimes. Non-Hispanic Multiracial women experienced a higher prevalence of all three outcomes compared with non-Hispanic White, non-Hispanic Black, and Hispanic women. Among victims who experienced pregnancy from rape, 28% experienced a sexually transmitted disease, 66% were injured, and over 80% were fearful or concerned for their safety. CONCLUSIONS: Pregnancy as a consequence of rape or sexual coercion is experienced by an estimated 6 million U.S. women. Prevention efforts may include health care screenings to identify violence exposure and use of evidence-based prevention approaches to reduce sexual violence.

Childhood violence victimization is a serious adverse childhood experience with lasting health impacts. This study examined the prevalence and characteristics of five forms of childhood violence victimization and their association with revictimization and negative health conditions among adults. Data are from the 2010-2012 National Intimate Partner and Sexual Violence Survey. Age at first victimization and perpetrator sex were assessed; adjusted odds ratios assessed associations with revictimization and health. Ages 14-17 were the most common age at first victimization for most violence types; almost half of male (46.7%) and a quarter of female (27.0%) rape victims reported first victimization before age 10. Most victimization was associated with revictimization and negative health, controlling for adult victimization. Primary prevention of childhood violence may reduce later health risks.

Sexual violence is a significant public health problem with long-term health implications. Previous investigations of male victimization have often relied on nongeneralizable samples to examine the health consequences of rape. Furthermore, made to penetrate (MTP) victimization has received very little attention as a specific form of sexual violence. Using data from the 2010 to 2012 National Intimate Partner and Sexual Violence Survey, we examined negative impacts (e.g., injury) and health conditions associated with experiences of rape and MTP among male victims in the United States. Results indicate that approximately 1 in 4 victims of rape-only and 1 in 12 victims of MTP-only reported physical injuries. An estimated 62.7% of rape-only victims and 59.8% of MTP-only victims reported at least one impact due to the perpetrator's violence. Rape victims were significantly more likely than non-rape victims to report 2 of 11 health conditions measured, while MTP victims had greater odds of reporting 6 of 11 health conditions measured compared to non-MTP victims. This article fills gaps in understanding the impacts of rape and MTP on male victims, and it is the only study to do so using a large, nationally representative sample. Sexual violence is linked to serious health effects but is also preventable. Screening for violence victimization and preventing male sexual violence before it happens are both important to reduce the risk for immediate and chronic health impacts.

PROBLEM/CONDITION: Homicide is a leading cause of death for American Indians/Alaska Natives (AI/ANs). Intimate partner violence (IPV) contributes to many homicides, particularly among AI/AN females. This report summarizes data from CDC's National Violent Death Reporting System (NVDRS) on AI/AN homicides. Results include victim and suspect sex, age group, and race/ethnicity; method of injury; type of location where the homicide occurred; precipitating circumstances (i.e., events that contributed to the homicide); and other selected characteristics. PERIOD COVERED: 2003-2018. DESCRIPTION OF SYSTEM: NVDRS collects data regarding violent deaths obtained from death certificates, coroner/medical examiner reports, and law enforcement reports and links related deaths (e.g., multiple homicides and homicide followed by suicide) into a single incident. This report includes data on AI/AN homicides that were collected from 34 states (Alabama, Alaska, Arizona, California, Colorado, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Utah, Virginia, Washington, and Wisconsin) and the District of Columbia. RESULTS: NVDRS collected data on 2,226 homicides of AI/ANs in 34 states and the District of Columbia during 2003-2018. The age-adjusted AI/AN homicide rate was 8.0 per 100,000 population. The homicide rate was three times higher in AI/AN males than females (12.0 versus 3.9), and the median age of AI/AN victims was 32 years (interquartile range: 23-44 years). Approximately half of AI/AN homicide victims lived or were killed in metropolitan areas (48.2% and 52.7%, respectively). A firearm was used in nearly half (48.4%) of homicides and in a higher percentage of homicides of AI/AN males than females (51.5% versus 39.1%). More AI/AN females than males were killed in a house or apartment (61.8% versus 53.7%) or in their own home (47.7% versus 29.0%). Suspects were identified in 82.8% of AI/AN homicides. Most suspects were male (80.1%), and nearly one third (32.1%) of suspects were AI/ANs. For AI/AN male victims, the suspect was most often an acquaintance or friend (26.3%), a person known to the victim but the exact nature of the relationship was unclear (12.3%), or a relative (excluding intimate partners) (10.5%). For AI/AN female victims, the suspect was most often a current or former intimate partner (38.4%), an acquaintance or friend (11.5%), or a person known to the victim but the exact nature of the relationship was unclear (7.9%). A crime precipitated 24.6% of AI/AN homicides (i.e., the homicide occurred as the result of another serious crime). More AI/AN males were victims of homicides due to an argument or conflict than females (54.7% versus 37.3%), whereas more AI/AN females were victims of homicides due to IPV than males (45.0% versus 12.1%). For homicides related to IPV, 87.2% of AI/AN female victims were killed by a current or former intimate partner, whereas approximately half (51.5%) of AI/AN male victims were corollary victims (i.e., victims killed during an IPV-related incident who were not the intimate partners themselves). INTERPRETATION: This report provides a detailed summary of NVDRS data on AI/AN homicides during 2003-2018. Interpersonal conflict was a predominant circumstance, with nearly half of all AI/AN homicides precipitated by an argument and for female victims, 45.0% precipitated by IPV. PUBLIC HEALTH ACTION: NVDRS provides critical and ongoing data on AI/AN homicides that can be used to identify effective and early intervention strategies for preventing these deaths. When possible, violence prevention efforts should include community-developed, culturally relevant, and evidence-based strategies. These efforts should incorporate traditional native knowledge and solutions, implement and possibly adapt evidence-based IPV and other violence prevention strategies, and consider the influence of historical and larger societal factors that increase the likelihood of violence in AI/AN communities.

The authors examine the prevalence and characteristics of sexual violence victimization - rape and being made to penetrate [MTP] (men only) - involving substances (alcohol or other drugs). Although it has been well-documented that perpetrators commit sexual violence against individuals who are using alcohol or drugs, more research is needed to describe the problem at a national level. Data are from the 2010-2012 National Intimate Partner and Sexual Violence Survey, a nationally representative random-digit-dial telephone survey of English- and Spanish-speaking adults in the United States (n = 41,174). Findings reveal that among victims of physically forced rape, 26.2 % of female and 30.0 % of male victims reported substance use; 44.5 % of male MTP victims reported substance use. The majority of forced rape and MTP victims reported the perpetrator was using alcohol or drugs. Among victims of alcohol/drug-facilitated rape, 29.7 % of female and 32.4 % of male victims reported involuntary use of substances, mostly drugs; 84.0 % of female and 82.6 % of male victims reported voluntary use. Among male victims of alcohol/drug-facilitated MTP, 14.6 % reported involuntary and 85.4 % reported voluntary use of substances. Female and male victims reported that the majority of intimate partner, acquaintance, and stranger perpetrators were using substances during the victimization. These findings suggest the importance of prevention efforts at the individual and community levels to reduce substance-involved sexual violence perpetration and risk reduction programs to reduce the likelihood of voluntary substance-facilitated sexual violence victimization.

INTRODUCTION: Intimate partner violence is associated with adverse health consequences among people with diagnosed HIV, which could have implications for disease progression and transmission. However, nationally representative estimates of intimate partner violence among people with diagnosed HIV are lacking. Investigators used nationally representative data to estimate the prevalence of physical violence by an intimate partner among adults with diagnosed HIV and examine the differences by selected characteristics. METHODS: This analysis included interview and medical record data from the 2015-2017 cycles of the Medical Monitoring Project, analyzed in 2019. Weighted percentages and 95% CIs were used to report the prevalence of intimate partner violence among people with diagnosed HIV (N=11,768). Bivariate and multivariate differences in intimate partner violence by sociodemographic, behavioral, and clinical characteristics were examined using Rao-Scott chi-square tests (p<0.05). RESULTS: Among people with diagnosed HIV, 26.3% reported having ever experienced intimate partner violence, and 4.4% reported having experienced intimate partner violence in the past 12 months. The prevalence of intimate partner violence differed by gender and gender/sexual identity. People who experienced intimate partner violence in the past 12 months were more likely to engage in behaviors associated with elevated HIV transmission risk and have unmet needs for supportive services. People who recently experienced intimate partner violence were less likely to be engaged in routine HIV care but were more likely to seek emergency care services and have poor HIV clinical outcomes. CONCLUSIONS: This study's findings support the need for screening people with diagnosed HIV for intimate partner violence and offering linkage to supportive services. Screening for intimate partner violence among people with diagnosed HIV, coupled with supportive services and counseling, may lead to improved safety and HIV clinical outcomes and decreased need for emergency and inpatient medical services.

Despite advances in the sexual violence (SV) prevention field, practitioners still face challenges with identifying indicators to measure the impact of their prevention strategies. Public data, such as existing administrative and surveillance system data, may be a good option for organizations to examine trends in indicators for the purpose of program evaluation. In this article, we describe a framework and a process for identifying indicators with public data. Specifically, we present the SV Indicator Framework and a five-step indicator review process, which we used to identify indicators for a national SV prevention program. We present the findings of the indicator review and explain how the process could be used by evaluators and program planners within other developing topic areas. Tracking indicators with public data, in conjunction with other evaluation methods, may be a viable option for state-level program evaluations. We discuss limitations and implications for practice and research.

Sexual violence (SV) is an urgent public health issue that is common and has lifelong effects on health. Previous scholarship has documented the association of SV victimization with numerous health conditions and impacts, but much of this past work has focused on negative health outcomes associated with child sexual abuse using non-nationally representative samples. This article used a nationally representative female sample to examine health conditions associated with any lifetime experience of rape. We also examined injury and health outcomes (e.g., fear, injury) resulting from any violence by a perpetrator of rape. About two in five rape victims (39.1%) reported injury (e.g., bruises, vaginal tears), and 12.3% reported a sexually transmitted disease as a result of the rape victimization. Approximately 71.3% of rape victims (an estimated 16.4 million women) experienced some form of impact as a result of violence by a rape perpetrator. Among U.S. women, the adjusted odds of experiencing asthma, irritable bowel syndrome, frequent headaches, chronic pain, difficulty sleeping, activity limitations, poor physical or mental health, and use of special equipment (e.g., wheelchair) were significantly higher for lifetime rape victims compared with non-victims. This article fills gaps in our understanding of health impacts associated with rape of women and is the only nationally representative source of this information to our knowledge. Primary prevention efforts in youth that seek to prevent the first occurrence of rape and other forms of SV may be most effective for reducing the long-term health effects of this violence.

Reproductive coercion (RC) is a specific type of intimate partner violence (IPV). Although clinical studies have highlighted women's experiences of RC, we know little about its national prevalence and differences in prevalence by sex category and race/ethnicity. Data are from the National Intimate Partner and Sexual Violence Survey (NISVS), years 2010 to 2012. NISVS is an ongoing, nationally representative random-digit-dial telephone survey of the noninstitutionalized English- or Spanish-speaking U.S. adult population. This article reports the national lifetime and 12-month prevalence of two RC victimization measures, and proportions among IPV victims. T tests were used to examine differences in estimates across racial/ethnic groups. In the United States, 9.7% of men and 8.4% of women experienced any RC by an intimate partner during their lifetime. Men reported more commonly than women that a partner tried to get pregnant when the man did not want her to; women reported higher prevalence of partner condom refusal. Examination by race/ethnicity revealed that non-Hispanic (NH) Black women and men had significantly higher lifetime prevalence of both RC types than all other groups; in the last 12 months, NH Blacks had significantly higher prevalence across the board than NH Whites. Hispanics had significantly higher lifetime and 12-month prevalence of any RC and partner condom refusal than NH Whites. RC is at the intersection of two public health concerns-IPV and reproductive health. Documenting its prevalence and differences by sex and race/ethnicity may inform prevention efforts to reduce occurrence and negative health outcomes among specific populations.

INTRODUCTION: Rape-related pregnancy is a public health problem where sexual violence and reproductive health intersect; yet, there is a dearth of research to inform public health practice. The authors examined the prevalence and characteristics of rape-related pregnancy in U.S. women and its association with intimate partner reproductive coercion. METHODS: Data years 2010-2012 are pooled from the National Intimate Partner and Sexual Violence Survey, a telephone survey of U.S. adults. Accounting for complex survey design, in 2017, authors estimated the prevalence of vaginal rape-related pregnancy for U.S. women overall and by race/ethnicity. The authors also examined the proportion of rape-related pregnancy among victims of vaginal rape overall, by perpetrator type and by presence of reproductive coercion in the context of intimate partner rape. RESULTS: Almost 2.9 million U.S. women (2.4%) experienced rape-related pregnancy during their lifetime. Among rape victims, 77.3% reported a current/former intimate partner perpetrator, and 26.2% of intimate partner rape victims reported rape-related pregnancy compared with those raped by an acquaintance (5.2%) or stranger (6.9%). Women raped by an intimate partner and reporting rape-related pregnancy were significantly more likely to have experienced reproductive coercion compared with women who were raped by an intimate partner but did not become pregnant. CONCLUSIONS: This paper reports the first national prevalence of rape-related pregnancy by any perpetrator in two decades. The high proportion of rape-related pregnancy committed by intimate partner perpetrators and its association with reproductive coercion suggest the need for primary prevention of intimate partner violence and access to trauma-informed reproductive health services for rape/intimate partner violence victims.

INTRODUCTION: Youth sexual violence victimization is an urgent public health concern that can lead to a variety of health problems and increased risk for victimization during adulthood. Examining the characteristics of early victimization and their association with subsequent victimization during adulthood may help strengthen primary prevention efforts. METHODS: Data are from the 2012 National Intimate Partner and Sexual Violence Survey. Prevalence estimates were computed in 2017 for rape and made to sexually penetrate, their subtypes, as well as proportions among victims by type of perpetrator. Chi-square tests of association were conducted between youth sexual violence victimization and the same experiences in adulthood. RESULTS: Approximately 10 million U.S. females (8.4%) experienced completed or attempted rape and 1.9 million U.S. males (1.6%) were made to penetrate someone during youth. Most victims knew their perpetrators. Being raped or made to penetrate during youth was associated with increased likelihood of such victimization in adulthood. CONCLUSIONS: Females and males experience youth sexual violence victimization at alarming rates. Primary prevention efforts with youth are critical to prevent early victimization, subsequent victimization in adulthood, and the mental and physical health consequences associated with sexual violence victimization.

INTRODUCTION: Previous research has consistently found that low SES is associated with higher levels of both intimate partner violence (IPV) and sexual violence (SV) victimization. Though associated with poverty, two indicators of economic insecurity, food and housing insecurity, have been identified as conceptually distinct social determinants of health. This study examined the relationship between food and housing insecurity experienced in the preceding 12 months and IPV and SV victimization experienced in the preceding 12 months, after controlling for SES and other demographic variables. METHODS: Data were from the 2010 National Intimate Partner and Sexual Violence Survey, a nationally representative telephone survey of U.S. adults. In 2016, multivariate logistic regression modeling was used to examine the association between food and housing insecurity and multiple forms of IPV and SV victimization. RESULTS: Robust associations were found between food and housing insecurity experienced in the preceding 12 months and IPV and SV experienced in the preceding 12 months, for women and men, even after controlling for age, family income, race/ethnicity, education, and marital status. CONCLUSIONS: Food and housing insecurity may be important considerations for the prevention of SV and IPV or the reductions of their consequences, although future research is needed to disentangle the direction of the association. Strategies aimed at buffering economic insecurity may reduce vulnerability to IPV and SV victimization.

Limited information exists on the relationship between sexual violence victimization and health among African American women. Using data from a community sample of African American women, we examine the association between current health and lifetime experiences of sexual violence. In-person interviews were completed in 2010. Among interviewees, 53.7% of women reported rape victimization and 44.8% reported sexual coercion in their lifetime. Victims of rape or sexual coercion were significantly more likely to report depression and posttraumatic stress disorder during their lifetime. Among victims whose first unwanted sexual experience was rape or sexual coercion, perpetrators were mostly acquaintances and intimate partners, and over one third were injured and needed services. More attention is needed on the health needs of African American women and their association to victimization status.

OBJECTIVES: To examine the relative prevalence of recent (past 12 months) penetrative and nonpenetrative sexual violence comparing men and women with and without a disability. METHODS: Data are from the 2010 National Intimate Partner and Sexual Violence Survey, a national telephone survey of US adults, and includes an expansive measure of sexual violence victimization. A total of 9086 women and 7421 men completed the telephone survey in 2010. RESULTS: Compared with persons without a disability, persons with a disability were at increased risk for recent rape for women (adjusted odds ratio = 3.3; 95% confidence interval = 1.6, 6.7), and being made to penetrate a perpetrator for men (adjusted odds ratio = 4.2; 95% confidence interval = 1.6, 10.8). An estimated 39% of women raped in the 12 months preceding the survey had a disability at the time of the rape. For women and men, having a disability was associated with an increased risk of sexual coercion and noncontact unwanted sexual experiences. CONCLUSIONS: In this nationally representative sample, men and women with a disability were at increased risk for recent sexual violence, compared to those without a disability.

This study sought to add to the limited information currently available on circumstances of sexual violence victimization and associated negative health experiences among Hispanic women. Data come from a community sample of mostly Mexican women in an urban southwestern city. Household interviews were completed with a sample of 142 women during 3 months in 2010. Findings indicate that 31.2% of women reported rape victimization and 22.7% reported being sexually coerced in their lifetime. Victims of rape and/or sexual coercion were significantly more likely to report symptoms of depression and post-traumatic stress disorder (PTSD) during their lifetime. Among victims whose first unwanted sexual experience resulted in rape and/or sexual coercion, perpetrators were almost always someone known to the victims, and were mostly family members or intimate partners, depending on the victim’s age. About one-fifth of victims were injured and 17.1% needed medical services. These findings suggest the need for more attention to the physical and mental health needs of sexually victimized Hispanic women.

PROBLEM/CONDITION: Sexual violence, stalking, and intimate partner violence are public health problems known to have a negative impact on millions of persons in the United States each year, not only by way of immediate harm but also through negative long-term health impacts. Before implementation of the National Intimate Partner and Sexual Violence Survey (NISVS) in 2010, the most recent detailed national data on the public health burden from these forms of violence were obtained from the National Violence against Women Survey conducted during 1995-1996. This report examines sexual violence, stalking, and intimate partner violence victimization using data from 2011. The report describes the overall prevalence of sexual violence, stalking, and intimate partner violence victimization; racial/ethnic variation in prevalence; how types of perpetrators vary by violence type; and the age at which victimization typically begins. For intimate partner violence, the report also examines a range of negative impacts experienced as a result of victimization, including the need for services. REPORTING PERIOD: January-December, 2011. DESCRIPTION OF SYSTEM: NISVS is a national random-digit-dial telephone survey of the noninstitutionalized English- and Spanish-speaking U.S. population aged ≥18 years. NISVS gathers data on experiences of sexual violence, stalking, and intimate partner violence among adult women and men in the United States by using a dual-frame sampling strategy that includes both landline and cellular telephones. The survey was conducted in 50 states and the District of Columbia; in 2011, the second year of NISVS data collection, 12,727 interviews were completed, and 1,428 interviews were partially completed. RESULTS: In the United States, an estimated 19.3% of women and 1.7% of men have been raped during their lifetimes; an estimated 1.6% of women reported that they were raped in the 12 months preceding the survey. The case count for men reporting rape in the preceding 12 months was too small to produce a statistically reliable prevalence estimate. An estimated 43.9% of women and 23.4% of men experienced other forms of sexual violence during their lifetimes, including being made to penetrate, sexual coercion, unwanted sexual contact, and noncontact unwanted sexual experiences. The percentages of women and men who experienced these other forms of sexual violence victimization in the 12 months preceding the survey were an estimated 5.5% and 5.1%, respectively. An estimated 15.2% of women and 5.7% of men have been a victim of stalking during their lifetimes. An estimated 4.2% of women and 2.1% of men were stalked in the 12 months preceding the survey. With respect to sexual violence and stalking, female victims reported predominantly male perpetrators, whereas for male victims, the sex of the perpetrator varied by the specific form of violence examined. Male rape victims predominantly had male perpetrators, but other forms of sexual violence experienced by men were either perpetrated predominantly by women (i.e., being made to penetrate and sexual coercion) or split more evenly among male and female perpetrators (i.e., unwanted sexual contact and noncontact unwanted sexual experiences). In addition, male stalking victims also reported a more even mix of males and females who had perpetrated stalking against them. The lifetime and 12-month prevalences of rape by an intimate partner for women were an estimated 8.8% and 0.8%, respectively; an estimated 0.5% of men experienced rape by an intimate partner during their lifetimes, although the case count for men reporting rape by an intimate partner in the preceding 12 months was too small to produce a statistically reliable prevalence estimate. An estimated 15.8% of women and 9.5% of men experienced other forms of sexual violence by an intimate partner during their lifetimes, whereas an estimated 2.1% of both men and women experienced these forms of sexual violence by a partner in the 12 months before taking the survey. Severe physical violence by an intimate partner (including acts such as being hit with something hard, being kicked or beaten, or being burned on purpose) was experienced by an estimated 22.3% of women and 14.0% of men during their lifetimes and by an estimated 2.3% of women and 2.1% of men in the 12 months before taking the survey. Finally, the lifetime and 12-month prevalence of stalking by an intimate partner for women was an estimated 9.2% and 2.4%, respectively, while the lifetime and 12-month prevalence for men was an estimated 2.5% and 0.8%, respectively. Many victims of sexual violence, stalking, and intimate partner violence were first victimized at a young age. Among female victims of completed rape, an estimated 78.7% were first raped before age 25 years (40.4% before age 18 years). Among male victims who were made to penetrate a perpetrator, an estimated 71.0% were victimized before age 25 years (21.3% before age 18 years). In addition, an estimated 53.8% of female stalking victims and 47.7% of male stalking victims were first stalked before age 25 years (16.3% of female victims and 20.5% of male victims before age 18 years). Finally, among victims of contact sexual violence, physical violence, or stalking by an intimate partner, an estimated 71.1% of women and 58.2% of men first experienced these or other forms of intimate partner violence before age 25 years (23.2% of female victims and 14.1% of male victims before age 18 years). INTERPRETATION: A substantial proportion of U.S. female and male adults have experienced some form of sexual violence, stalking, or intimate partner violence at least once during their lifetimes, and the sex of perpetrators varied by the specific form of violence examined. In addition, a substantial number of U.S. adults experienced sexual violence, stalking, or intimate partner violence during the 12 months preceding the 2011 survey. Consistent with previous studies, the overall pattern of results suggest that women, in particular, are heavily impacted over their lifetime. However, the results also indicate that many men experience sexual violence, stalking, and, in particular, physical violence by an intimate partner. Because of the broad range of short- and long-term consequences known to be associated with these forms of violence, the public health burden of sexual violence, stalking, and intimate partner violence is substantial. Results suggest that these forms of violence frequently are experienced at an early age because a majority of victims experienced their first victimization before age 25 years, with a substantial proportion experiencing victimization in childhood or adolescence. PUBLIC HEALTH ACTION: Because a substantial proportion of sexual violence, stalking, and intimate partner violence is experienced at a young age, primary prevention of these forms of violence must begin early. Prevention efforts should take into consideration that female sexual violence and stalking victimization is perpetrated predominately by men and that a substantial proportion of male sexual violence and stalking victimization (including rape, unwanted sexual contact, noncontact unwanted sexual experiences, and stalking) also is perpetrated by men. CDC seeks to prevent these forms of violence with strategies that address known risk factors for perpetration and by changing social norms and behaviors by using bystander and other prevention strategies. In addition, primary prevention of intimate partner violence is focused on the promotion of healthy relationship behaviors and other protective factors, with the goal of helping adolescents develop these positive behaviors before their first relationships. The early promotion of healthy relationships while behaviors are still relatively modifiable makes it more likely that young persons can avoid violence in their relationships.

OBJECTIVES: We estimated the frequency and examined the characteristics of intimate partner homicide and related deaths in 16 US states participating in the National Violent Death Reporting System (NVDRS), a state-based surveillance system. METHODS: We used a combination of quantitative and qualitative methods to analyze NVDRS data from 2003 to 2009. We selected deaths linked to intimate partner violence for analysis. RESULTS: Our sample comprised 4470 persons who died in the course of 3350 intimate partner violence-related homicide incidents. Intimate partners and corollary victims represented 80% and 20% of homicide victims, respectively. Corollary homicide victims included family members, new intimate partners, friends, acquaintances, police officers, and strangers. CONCLUSIONS: Our findings, from the first multiple-state study of intimate partner homicide and corollary homicides, demonstrate that the burden of intimate partner violence extends beyond the couple involved. Systems (e.g., criminal justice, medical care, and shelters) whose representatives routinely interact with victims of intimate partner violence can help assess the potential for lethal danger, which may prevent intimate partner and corollary victims from harm.

During 1991--2007, homicide was ranked as one of the top four leading causes of death each year for persons aged 1--40 years living in the United States (1). Furthermore, vast disparities in homicide rates have been reported between males and females and among different age and racial/ethnic groups (2--6). For example, previous studies have indicated that rates of death from homicide are particularly high among males (4--6), persons aged 15--34 years and <1 year (5), and blacks (2,3,5,6). Homicide rates for males are estimated to be approximately 3--4 times higher than that for females (4,5); among persons aged 20--24 years, the male homicide rate is 6 times higher than that for females (1,5). In addition, minority racial/ethnic children and young adults in the United States are disproportionately affected by homicide. During 1999--2002, among persons aged 10--19 years, the homicide rate for blacks was estimated to be 17.8 per 100,000 population, a rate 10 times that of whites (1.8 per 100,000) and higher than the rates reported for American Indians/Alaska Natives (AI/ANs) (6.0 per 100,000), Asian/Pacific Islanders (A/PIs) (2.9 per 100,000), and Hispanics (8.0 per 100,000) (2). | | To assess homicide rates in the United States by sex, age, and race/ethnicity for 2007, CDC assessed data from the CDC Web-based Injury Statistics Query and Reporting System --- Fatal (WISQARS Fatal) (1). This report summarizes these rates, identifies specific population groups with the highest rates of death from homicide, and provides homicide rates by race/ethnicity and year throughout a 9-year period (1999--2007). Additional details on homicide rates by these variables for each state and census region can be accessed through the WISQARS Fatal online query system (http://www.cdc.gov/injury/wisqars/index.html). Data on individual and socioeconomic risk factors for homicide were unavailable for analysis. In addition, sufficient data were unavailable to assess disparities by certain racial/ethnic subgroups, family income, educational attainment, disability status, and sexual orientation.

OBJECTIVES: Few studies have examined the association between non-consensual sex and health indicators for both women and men. The current study examined this relationship as part of a large public health survey that collected information on a range of health behaviours and health risks. METHODS: The Behavioural Risk Factor Surveillance System (BRFSS) is an annual random-digit-dialled telephone survey providing surveillance of health behaviours and health risks among US adults. In 2005, an optional module on sexual violence was available for use at the discretion of each US state/territory. Over 115,000 respondents in 25 states/territories were administered the sexual violence module within the BRFSS. Logistic regression analyses were conducted from January to December 2008. RESULTS: Among both women and men, previous non-consensual sex was associated with health conditions such as high cholesterol, stroke and heart disease, and risk behaviours such as human immunodeficiency virus risk factors, smoking and excessive drinking. Sexually victimized women were more likely to report having had a heart attack or heart disease than non-victims. CONCLUSIONS: The experience of non-consensual sex is associated with a number of chronic disease outcomes and risk factors. The development and implementation of effective sexual violence prevention strategies may reduce the risk of chronic conditions among persons who have experienced sexual victimisation.
