title: [Chronic pain in schizophrenic patients: prevalence and characteristics].
abstract: Chronic pain may be at least as prevalent in psychiatric patients as in the general population. To estimate the prevalence of chronic pain in schizophrenic patients, compare the groups with and without chronic pain, and characterize the pain, a cross-sectional study was performed on a probabilistic sample of 205 adult patients with a diagnosis of schizophrenia (mean age 37 years; 65% men; mean schooling nine years; 87% single; 65% living with parents), treated at a public hospital in the city of São Paulo, Brazil. Prevalence of pain was 36.6%, and the most frequent sites were abdomen (30.7%), head, face, and mouth (24%), and lower back (14.7%). Twenty-four percent of patients reported feeling pain every day. Mean duration of pain was 41 months, with moderate intensity. Prevalence of chronic pain in schizophrenic patients was similar to that in the general population, and the clinical course was significant in terms of duration, intensity, and frequency.
