Rates of femicide in women of different races, ethnicities, and places of birth: Massachusetts, 1993-2007.

To describe the epidemiology of intimate partner violence (IPV) homicide in Massachusetts, an IPV mortality data set developed by the Massachusetts Department of Public Health was analyzed. The rates of death were estimated by dividing the number of decedents over the aged-matched population and Poisson regression was used to estimate the contribution of race, ethnicity, and foreign-born status to the risk of dying from IPV. Out of the total 270 women whose deaths were associated with IPV, 239 (89%) were killed by a male partner. Black women had a risk of dying from IPV of 16.2 per 1,000,000 person-years. Hispanic women also had a higher risk of dying from IPV than non-Hispanic women; incidence risk ratio of 9.7 (Poisson regression 95% confidence interval 6.8-13.8). IPV femicide disproportionately affected Black and Hispanic women. Agencies must consider the importance of providing culturally appropriate services to IPV survivors and their community.
