Personality disorders and physical comorbidities in adults from the United States: data from the national epidemiologic survey on alcohol and related conditions.

There is a paucity of research examining the relationship between personality disorders (PDs) and chronic physical comorbidities. Consequently, we investigated associations between individual PDs and PD Clusters, and various common disease groups [cardiovascular disease (CVD), diabetes, arthritis and gastrointestinal disease (GI)] in a nationally representative survey of adults from the United States.
