The association of peptic ulcer and schizophrenia: A population-based study

AbstractBackground sociation of schizophrenia with peptic ulcer is not conclusive. In the last 30 years, there has been little evaluation of peptic ulcer among schizophrenia patients. s lore the relation of peptic ulcer and schizophrenia during this new phase, we used the data from Taiwan insurance claims, identified 1496 schizophrenia patients (ICD-9-CM: 295) and selected 5984 non-schizophrenia controls that were frequency-matched by sex, age, and index year with schizophrenia patients during the years 1998–2001. All subjects were free of peptic ulcer at baseline. We measured incidences of peptic ulcer (ICD-9-CM: 531–534) until the end of 2009. s cidence of peptic ulcer was 1.27 times higher in schizophrenia patients than in the control group (12.1vs. 9.52 per 1000 person-years). Patients are at higher risk taking anti-depression, anxiolytic and hypnotics or non-steroidal anti-inflammatory drugs. After controlling the confounding factors, schizophrenia patients had no significant increase incidence of peptic ulcer. sion phrenia patients have a slightly higher risk of peptic ulcer compared to the general population. This might be due to a higher rate of taking anti-depression, anxiolytic and hypnotics or non-steroidal anti-inflammatory drugs and alcoholism among this group.
