Results are published in the July issue of Alcoholism: Clinical & Experimental Research.

Gruenewald is also the first author of the study.
Using hospital-discharge data on violent assaults rather than crime reports from law enforcement officials also helps to control reporting biases, added Richard Scribner, professor of preventive medicine at Louisiana State University Health Sciences Center. "For example, residents of a neighborhood with high levels of police mistrust migh
