OBJECTIVE: Studies have reported that up to 60% of individuals with schizophrenia and 68% of those with bipolar disorder are overweight/obese. This paper explores the health-related quality of life (HRQOL) of individuals with schizophrenia or bipolar disorder as a function of obesity status. METHODS AND PROCEDURES: Two hundred and eleven participants were recruited from four psychiatric programs (outpatient, day treatment, case management, and psychosocial rehabilitation). HRQOL was assessed using both a general measure (Medical Outcomes Study Short-Form-36 (SF-36)) and a weight-related measure (Impact of Weight on Quality of Life-Lite (IWQOL-Lite)). To interpret HRQOL scores obtained by the obese group, we compared scores to those obtained by reference groups from the weight-loss literature. RESULTS: Sixty-three percent of participants with schizophrenia and 68% of those with bipolar disorder were obese. Obese participants were more likely to be women, on mood stabilizers, taking a greater number of psychiatric medications, and to have poorer weight-related and general HRQOL. Weight-related HRQOL in the obese psychiatric sample was more impaired than in outpatient and day treatment samples seeking weight loss but less impaired than in gastric-bypass patients. Several of the physical domains of general HRQOL were more impaired for the obese psychiatric sample than for the outpatient weight-loss sample. However, physical functioning was less impaired for the obese psychiatric ...
