title: Higher Risk of Homicide Among Pregnant and Postpartum Females Aged 10-29 Years in Illinois, 2002-2011.
abstract: To examine whether being pregnant or postpartum was associated with excess risk for homicide among females in Illinois and to describe the association between pregnancy status and homicide by race, ethnicity, and age group.
  
  
  
  This is a retrospective, multicohort, ecologic study of females of reproductive age in Illinois between 2002 and 2011 using Illinois Department of Public Health maternal mortality data and vital records data. We compared pregnancy-associated homicides with live births using χ tests. Among maternal deaths in the state, we calculated mortality rates per 100,000 live births for homicide and other violent causes and the leading direct obstetric causes. We calculated aggregate, pregnancy-associated, and nonpregnancy associated homicide rates stratified by race or ethnicity and age group.
  
  
  
  There were 636 pregnancy-associated deaths in Illinois from 2002 to 2011. Of these, 82 (13%) were the result of homicide (5.0 [95% confidence interval (CI) 4.0-6.2]/100,000 live births). There were 931 homicides among females of reproductive age not associated with pregnancy (2.88 [95% CI 2.70-3.07]/100,000 population). More than half of the homicides were women aged 20-29 years (n=53 [64.6%]), non-Hispanic black women (n=43 [52.4%]), women residing in Cook County (n=47 [57.3%]), and unmarried women (n=57 [69.5%]). Pregnant and postpartum females aged 10-29 years were at twice the risk of homicide compared with their nonpregnant or postpartum counterparts (relative risk 2.20 [95% CI 1.70-2.85]). Non-Hispanic black and Hispanic females experienced higher rates of homicide than non-Hispanic white females irrespective of pregnancy or age.
  
  
  
  Although all violence against women must be addressed, we recommend that state maternal mortality review committees, in addition to reviewing deaths resulting from obstetric and clinical causes, should conduct in-depth reviews of pregnancy-associated homicides and other violent deaths.
