title: Symptoms of anxiety and depression: A comparison among patients with different chronic conditions.
abstract: BACKGROUND
  Although patients with chronic diseases are at high-risk for symptoms of anxiety and depression, few studies have compared patients with different chronic conditions in this regard. This study aimed to compare patients with different chronic medical conditions in terms of anxiety and depression symptoms after controlling for the effects of socio-demographic and clinical data.
  
  
  METHODS
  This cross-sectional study enrolled 2234 adults, either healthy (n = 362) or patients with chronic medical conditions (n = 1872). Participants were recruited from the outpatient clinic of Baqiyatallah Hospital, Tehran, Iran. Patients had one of the following five medical conditions: coronary artery disease (n = 675), renal transplantation (n = 383), chronic hemodialysis (n = 68), rheumatoid conditions (rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus and ankylosing spondylitis) (n = 666) and viral hepatitis (n = 80). Independent factors included socio-demographic data, pain disability, and somatic comorbidities (Ifudu index). Outcomes included symptoms of anxiety and depression through Hospital Anxiety and Depression Scale (HADS). Two multinomial regression models were used to determine the predictors of anxiety and depression symptoms.
  
  
  RESULTS
  After controlling the effect of age, sex, educational level, comorbidities, disability and pain, rheumatoid arthritis and hepatitis were predictors of higher anxiety symptoms, while coronary artery disease and chronic hemodialysis were predictors of depression symptoms.
  
  
  CONCLUSIONS
  Although all chronic conditions may require psychological consideration; be that as it may, different chronic diseases are dissimilar in terms of their mental health need. Anxiety for rheumatoid arthritis and hepatitis as well as depression for coronary artery disease and chronic hemodialysis is more important.
