Disordered Eating among People with Schizophrenia Spectrum Disorders: A Systematic Review.

Disordered eating, or abnormal eating behaviours that do not meet the criteria for an independent eating disorder, have been reported among people with schizophrenia. We aimed to systemati-cally review literature on disordered eating among people with schizophrenia spectrum disorder (SSD). Seven databases were systematically searched for studies that described the prevalence and correlates of disordered eating among patients with SSD from January 1984 to 15 February 2021. Qualitative analysis was performed using the National Institutes of Health scales. Of 5504 records identified, 31 studies involving 471,159 subjects were included in the systematic review. The ma-jority of studies (17) rated fair on qualitative analysis and included more men, and participants in their 30s and 40s, on antipsychotics. The commonest limitations include lack of sample size or power calculations, poor sample description, not using valid tools, or not adjusting for con-founders. The reported rates were 4.4% to 45% for binge eating, 16.1% to 64%, for food craving, 27% to 60.6% for food addiction, and 4% to 30% for night eating. Positive associations were re-ported for binge eating with antipsychotic use and female gender, between food craving and weight gain, between food addiction and increased dietary intake, and between disordered eating and female gender, mood and psychotic symptoms. Reported rates for disordered eating among people with SSD are higher than those in the general population. We will discuss the clinical, treatment and research implications of our findings.

United Kingdom substance misuse treatment workers' attitudes toward 12-step self-help groups.

Research has highlighted the benefits of professional substance misuse treatment workers facilitating their clients' involvement in 12-step self-help groups such as Alcoholics Anonymous (AA) and Narcotics Anonymous (NA). This study used a cross-sectional survey design to explore the attitudes of substance misuse treatment staff working in the English West Midlands region toward AA and NA and the 12-step philosophy. A total of 346 treatment workers responded (71%). Fewer than 10% used the 12-step model in their treatment work, and only a third felt that their clients were generally suited to AA or NA. Fewer than half (46%) said that they were likely to recommend that their clients attend a self-help group meeting. Staff with nursing qualifications were more likely to have a positive attitude toward AA/NA than their non-nursing colleagues, and there was a statistically significant association between the level of reported spirituality of the workers and the likelihood of them recommending to clients that they attend AA or NA meetings. These results highlight differences in the role of AA/NA within the substance misuse treatment system in the United Kingdom and that in the United States; possible explanations are discussed.
