iolence against children continues to grow as a salient issue in national and international public health and public policy discussions. 1,2 However, epidemiology to accurately describe the problem and track trends continues to be a stumbling block in the United States and elsewhere. Available data have not resolved disagreements about whether physical abuse of children in the United States has been increasing [3][4][5] or decreasing 6 or whether bullying is an epidemic 7,8 or on the decline. 9 A recent National Academies Press report pointed to problems in the epidemiology of child maltreatment and called for a "high-quality, populationbased, epidemiological surveillance system that draws on multiple data sources." 10 The most important recent initiative to improve child maltreatment epidemiology is a joint effort of the US Department of Justice and the Centers for Disease Control and Prevention initiated in 2008 entitled the National Survey of Children's Exposure to Violence (NatSCEV). 11 Repeated assessments have occurred at 3-year intervals, 12 in 2011 and now in 2014. The availability of this surveillance system means that policy makers and health care professionals can have current information on prevalences and trends. The NatSCEV provides ongoing national estimates of a wide range of violence against youth, including the only national source of information about crimes against children younger than 12 years that are not reported to authorities. IMPORTANCE It is important to estimate the burden of and trends for violence, crime, and abuse in the lives of children.OBJECTIVE To provide health care professionals, policy makers, and parents with current estimates of exposure to violence, crime, and abuse across childhood and at different developmental stages.
DESIGN, SETTING, AND PARTICIPANTSThe National Survey of Children's Exposure to Violence (NatSCEV) includes a representative sample of US telephone numbers from August 28, 2013, to April 30, 2014. Via telephone interviews, information was obtained on 4000 children 0 to 17 years old, with information about exposure to violence, crime, and abuse provided by youth 10 to 17 years old and by caregivers for children 0 to 9 years old.MAIN OUTCOME AND MEASURE Exposure to violence, crime, and abuse using the Juvenile Victimization Questionnaire.
RESULTSIn total, 37.3% of youth experienced a physical assault in the study year, and 9.3% of youth experienced an assault-related injury. Two percent of girls experienced sexual assault or sexual abuse in the study year, while the rate was 4.6% for girls 14 to 17 years old. Overall, 15.2% of children and youth experienced maltreatment by a caregiver, including 5.0% who experienced physical abuse. In total, 5.8% witnessed an assault between parents. Only 2 significant rate changes could be detected compared with the last survey in 2011, namely, declines in past-year exposure to dating violence and lifetime exposure to household theft.
CONCLUSIONS AND RELEVANCEChildren and youth are exposed to violence, abuse, and crime in ...
