The prevalence of bipolar mood disorders in the medically ill patients hospitalized in general hospitals

Abstract

Introduction Bipolar mood disorders are the eighth cause of disability in the world. Several studies have shown the prevalence of bipolar disorders in patients with medical diseases is higher than healthy controls. Aims This study aimed to investigate the prevalence of bipolar disorders in the medically ill patients hospitalized in general hospitals. Methods In this cross-sectional study, 706 patients (342 men, 49%) admitted to different wards of three general hospitals randomly enrolled to the study. Demographic questionnaire, MDQ (Mood Disorder Questionnaire) and BSDS (Bipolar spectrum Diagnostic Scale) were used. The criteria for inclusion were informed consent and cooperation for the study, lack of cognitive and mental disorders and being literate. Results In 84 (12.1%) and 145 (20.8%) patients, respectively BSDS and MDQ questionnaire results were positive. In 75% of patients, the results of both tests were negative, while in 9.7% of hospitalized patients, the results of both tests were positive. The frequency of bipolar mood disorders was not significantly different between male and female, but the frequency of bipolar disorders was significantly higher in singles, smokers, alcohol abusers, younger age and lower education level. The highest rate of bipolar disorders was reported in the orthopaedic ward. Conclusion The prevalence of bipolar mood disorders in hospitalized medically ill patients is significant, due to the impact of the disorder on the lifestyle, compliance and the prognosis, identification and treatment of bipolar mood disorders is important in these patients.
