title: Physical comorbidity and 12-week treatment outcomes in Korean patients with depressive disorders: the CRESCEND study.
abstract: OBJECTIVE
  Physical and depressive disorders frequently co-occur, but effects of physical health on depression treatment outcomes have received little research. This study aimed to compare treatment outcomes between people with depressive disorder with and without comorbid physical disorders.
  
  
  METHODS
  A Korean nationwide sample of 723 people with depressive disorder initiated on antidepressant treatment, and re-evaluated at 1, 2, 4, 8, and 12 weeks later. Assessment scales for evaluating depressive symptoms (HAMD), anxiety (HAMA), global severity (CGI-s), and functioning (SOFAS) were administered at baseline and every follow-up visit. Achievement of remission or response was defined only when these were maintained to the 12 weeks study endpoint or to the last follow-up examination, if earlier, with the date of the first observed remission point applied as the timing of remission. Logistic regression and Cox proportional hazards models were used.
  
  
  RESULTS
  Of the sample, 247 (34%) had at least one physical disorder. This was associated with lower socioeconomic status and more severe depressive symptoms at baseline, but was not associated with any treatment related characteristics including antidepressant type and regimen, concomitant medications, side effects, and duration of treatment period. After adjustment, patients with physical comorbidity responded more slowly and less often - particularly in domains of anxiety, global severity, and functioning (all p-values <.005).
  
  
  CONCLUSIONS
  More intensive assessment and integrated treatment approaches are needed to facilitate treatment responses for depressive disorders in people with physical comorbidity. Future comparative studies between conventional and integrated treatment approaches are indicated for depressive disorders with physical comorbidity.
