BACKGROUND Overweight and obesity are epidemic among persons with serious mental illness, yet weight-loss trials systematically exclude this vulnerable population. Lifestyle interventions require adaptation in this group because psychiatric symptoms and cognitive impairment are highly prevalent. Our objective was to determine the effectiveness of an 18-month tailored behavioral weight-loss intervention in adults with serious mental illness. METHODS We recruited overweight or obese adults from 10 community psychiatric rehabilitation outpatient programs and randomly assigned them to an intervention or a control group. Participants in the intervention group received tailored group and individual weight-management sessions and group exercise sessions. Weight change was assessed at 6, 12, and 18 months. RESULTS Of 291 participants who underwent randomization, 58.1% had schizophrenia or a schizoaffective disorder, 22.0% had bipolar disorder, and 12.0% had major depression. At baseline, the mean body-mass index (the weight in kilograms divided by the square of the height in meters) was 36.3, and the mean weight was 102.7 kg (225.9 lb). Data on weight at 18 months were obtained from 279 participants. Weight loss in the intervention group increased progressively over the 18-month study period and differed significantly from the control group at each follow-up visit. At 18 months, the mean between-group difference in weight (change in intervention group minus change in control group) was −3.2 kg (−7.0 lb, P = 0.002); 37.8% of the participants in the intervention group lost 5% or more of their initial weight, as compared with 22.7% of those in the control group (P = 0.009). There were no significant between-group differences in adverse events. CONCLUSIONS A behavioral weight-loss intervention significantly reduced weight over a period of 18 months in overweight and obese adults with serious mental illness. Given the epidemic of obesity and weight-related disease among persons with serious mental illness, our findings support implementation of targeted behavioral weight-loss interventions in this high-risk population.

Since publication of the original Schizophrenia Patient Outcomes Research Team (PORT) treatment recommendations in 1998, considerable scientific advances have occurred in our knowledge about how to help persons with schizophrenia. Today an even stronger body of research supports the scientific basis of treatment. This evidence, taken in its entirety, points to the value of treatment approaches combining medications with psychosocial treatments, including psychological interventions, family interventions, supported employment, assertive community treatment, and skills training. The most significant advances lie in the increased options for pharmacotherapy, with the introduction of second generation antipsychotic medications, and greater confidence and specificity in the application of psychosocial interventions. Currently available treatment technologies, when appropriately applied and accessible, should provide most patients with significant relief from psychotic symptoms and improved opportunities to lead more fulfilling lives in the community. Nonetheless, major challenges remain, including the need for (1) better knowledge about the underlying etiologies of the neurocognitive impairments and deficit symptoms that account for much of the disability still associated with schizophrenia; (2) treatments that more directly address functional impairments and that promote recovery; and (3) approaches that facilitate access to scientifically based treatments for patients, the vast majority of whom currently do not have such access.

People with schizophrenia may be at increased risk for Type II diabetes because of the side effects of antipsychotic medication, poorer overall physical health, less healthy lifestyles, and poorer health care. The present study uses data bases collected by the Schizophrenia Patient Outcomes Research Team (PORT) to assess the prevalence and demographic and clinical correlates of diabetes within large populations of persons receiving treatment for schizophrenia. In the Schizophrenia PORT, Medicaid and Medicare data from 1991 and more recent interview data were collected regarding the comorbidity of schizophrenia and diabetes: prevalence, quality of life, physical health, and services utilization and costs. The study found that rates of diagnosed diabetes exceeded general population statistics well before the widespread use of the new antipsychotic drugs. Risk factors for diabetes were similar to those observed in the general population. The linkage of diabetes to poor physical health, medical morbidity, and increased service use and cost requires attention. This study of diabetes in the early 1990s suggests that even before the widespread use of the atypical antipsychotic drugs, diabetes was a major problem for persons with schizophrenia.

The problem of violence against individuals with severe mental illness (SMI) has received relatively, little notice, despite several studies suggesting an exceptionally high prevalence of victimization in this population. This paper describes the results of an investigation of the prevalence and correlates of past year physical and sexual assault among a large sample of women and men with SMI drawn from inpatient and outpatient settings across 4 states. Results confirmed preliminary findings of a high prevalence of victimization in this population (with sexual abuse more prevalent for women and physical abuse more prevalent for men), and indicated the existence of a range of correlates of recent victimization, including demographic factors and living circumstances, history of childhood abuse, and psychiatric illness severity and substance abuse. The research and clinical implications of these findings are discussed.

As hypothesized, the Individual Placement and Support program was more effective than the psychosocial rehabilitation program in helping patients achieve employment goals. Achieving job retention remains a challenge with both interventions.

We studied the medical comorbidity among individuals with serious mental illness who were receiving community-based psychiatric treatment. A total of 200 psychiatric outpatients divided between those with schizophrenia and affective disorder diagnoses were recruited from samples receiving outpatient care at two psychiatric centers. Interviews used questions from national health surveys. Logistic regression analyses compared responses from each sample with those of matched subsets of individuals from the general population. Both patient groups had greater odds of having many medical conditions. The odds of respiratory illnesses remained elevated in the patient groups even after controlling for smoking, as did the odds of diabetes in the affective disorder group after controlling for weight. Persons with serious mental illness who are in outpatient care are more likely to have comorbid medical conditions than persons in the general population. The odds of diabetes, lung diseases, and liver problems are particularly elevated. These findings underscore the need for intensified preventive health interventions and medical services for this population.

Although physical inactivity is a leading cause of death and the Surgeon General recommends regular moderate physical activity, many Americans are inactive. Because of their increased burden of obesity and diabetes, people with severe mental illness (SMI) especially may benefit from physical activity, yet little is known about the prevalence and types of physical activity in people with SMI. We surveyed outpatients with schizophrenia and affective disorders at two psychiatric centers in Maryland and compared physical activity patterns to an age-gender-race-matched national sample (National Health and Nutrition Examination Survey III) of the general population. We found that people with SMI are overall less physically active than the general population, although the proportion with recommended physical activity levels was equal. The participants with SMI were more likely to walk as their sole form of physical activity. Within the SMI group, those without regular social contact and women had higher odds of being inactive.
