Two epidemiological studies of community samples approximated the lifetime prevalence of<unk>  to be 4–6%, depending on the criteria set used. A Ukrainian study found comparable rates of lifetime<unk>  (4.2%), suggesting that a lifetime prevalence of<unk>  of 4–6% is not limited to American samples. One-month and one-year point prevalences of<unk>  in these studies were reported as 2.0% and 2.7%, respectively. Extrapolating to the national level, 16.2 million Americans would have<unk>  during their lifetimes and as many as 10.5 million in any year and 6 million in any month. Among a clinical population, a 2005 study found the lifetime prevalence of<unk>  to be 6.3%. Prevalence appears to be higher in men than in women. Of US subjects with<unk> , 67.8% had engaged in direct interpersonal aggression, 20.9% in threatened interpersonal aggression, and 11.4% in aggression against objects. Subjects reported engaging in 27.8 high-severity aggressive acts during their worst year, with 2–3 outbursts requiring medical attention. Across the lifespan, the mean value of property damage due to aggressive outbursts was $1603. A study in the March 2016 Journal of Clinical Psychiatry suggests a relationship between infection with the parasite Toxoplasma gondii and psychiatric aggression such as<unk> .
