Background: Preoperative mental health seems to have useful predictive value for Health Related Quality of Life
(HRQOL) after bariatric surgery. The aim of the present study was to assess pre- and postoperative psychiatric
disorders and their associations with pre- and postoperative HRQOL.
Method: Data were assessed before (n = 127) and one year after surgery (n = 87). Psychiatric disorders were
assessed by Mini International Neuropsychiatric Interview (M.I.N.I.) and Structured Clinical Interview (SCID-II). HRQOL
was assessed by the Short Form 36 (SF-36) questionnaire.
Results: Significant improvements were found in HRQOL from preoperative assessment to follow-up one year after
surgery. For the total study population, the degree of improvement was statistically significant (p values < .001) for
seven of the eight SF-36 subscales from preoperative assessment to follow-up one year after surgery. Patients
without psychiatric disorders had no impairments in postoperative HRQOL, and patients with psychiatric disorders
that resolved after surgery had small impairments on two of the eight SF-36 subscales compared to the population
norm (all effect sizes < .5) at follow-up one year after surgery. Patients with psychiatric disorders that persisted after
surgery had impaired HRQOL at follow-up one year after surgery compared to the population norm, with effect
sizes for the differences from moderate to large (all effect sizes ≥ .6).
Conclusion: This study reports the novel finding that patients without postoperative psychiatric disorders achieved
a HRQOL comparable to the general population one year after bariatric surgery; while patients with postoperative
psychiatric disorders did not reach the HRQOL level of the general population. Our results support monitoring
patients with psychiatric disorders persisting after surgery for suboptimal improvements in quality of life after
bariatric surgery.
