RT Journal Article SR Electronic T1 Utility of indices of gun availability in the community JF Journal of Epidemiology and Community Health JO J Epidemiol Community Health FD BMJ Publishing Group Ltd SP 44 OP 49 DO 10.1136/jech.2005.039149 VO 60 IS 1 A1 Shenassa, Edmond D A1 Daskalakis, Constantine A1 Buka, Stephen L YR 2006 UL http://jech.bmj.com/content/60/1/44.abstract AB Objective: To estimate the degree to which the proportion of homicides and suicides committed with a gun is associated with reported availability of firearms across Chicago neighbourhoods. Methods: Data were collected as part of the Project on Human Development in Chicago Neighborhoods (PHDCN), a combined neighbourhood and individual level study of the city of Chicago. The study used data from 837 PHDCN participants between the ages of 17 and 22, residing in 170 different neighbourhoods. Gun availability was measured via participant reports on whether they had carried a gun and whether they perceived gun access to be easy in their community. Data on suicides and homicides were obtained from the Chicago Department of Health. Results: A 10% change in the proportion of homicides committed by a gun in a neighbourhood was associated with a 20% increase in both the odds of reported gun access and reported gun carrying (pā€Š=ā€Š0.002 and 0.048, respectively). The proportion of firearm related suicides was not associated with either of those self reported measures. Conclusions: The proportion of firearm related homicides, but not the proportion of firearm related suicides, is a useful predictor of gun availability across small areas such as neighbourhoods.
