Physical multimorbidity in psychiatric patients with personality disorders: Insights within the ICD-11 framework.

Objective: Recent research has revealed poor physical health among individuals with personality disorders (PDs). We aimed to compare chronic physical illnesses (CPI) and chronic physical multimorbidity (CPM) prevalence between the general population (GEP) and PD patients, and to explore the relationship between CPM and various aspects of PD, predominantly within the ICD-11 framework.

Methods: This cross-sectional study included 126 PD patients and 126 matched controls from the GEP.
