title: Rapid adipose deposition with mood disorders.
abstract: BACKGROUND
  Persons with bipolar disorder represent a high-risk group for obesity, but little is known about the time course by which weight gain occurs in bipolar disorder.
  
  
  METHODS
  We prospectively studied changes in fat distribution using dual-energy x-ray absorptiometry in relationship to medication exposure and mood symptom burden in 36 participants with bipolar disorder. We assessed the relationship between prior medication exposure and course of illness with adiposity measures at baseline (N = 36) and at 6-month follow-up (N = 22).
  
  
  RESULTS
  At baseline, greater adiposity was associated with advanced age and female sex, not retrospectively assessed symptom course or medication exposure (past 2 years). Over 6 months of prospective follow-up, participants developed greater adiposity (fat mass index +0.82 kg/m(²), P = .007; visceral fat area +8.6 cm(²), P = .02; total percent fat +1.6%, P = .02). Manic symptomatology, not antipsychotic exposure, was related to the increased adiposity.
  
  
  CONCLUSIONS
  Acute exacerbations of mood disorders appear to represent high-risk periods for adipose deposition. Obesity prevention efforts may be necessary during acute exacerbations.
