BackgroundObesity is a major challenge for people with schizophrenia.AimsWe assessed whether STEPWISE, a theory-based, group structured lifestyle education programme could support weight reduction in people with schizophrenia.MethodIn this randomised controlled trial (study registration: ISRCTN19447796), we recruited adults with schizophrenia, schizoaffective disorder or first-episode psychosis from ten mental health organisations in England. Participants were randomly allocated to the STEPWISE intervention or treatment as usual. The 12-month intervention comprised four 2.5 h weekly group sessions, followed by 2-weekly maintenance contact and group sessions at 4, 7 and 10 months. The primary outcome was weight change after 12 months. Key secondary outcomes included diet, physical activity, biomedical measures and patient-related outcome measures. Cost-effectiveness was assessed and a mixed-methods process evaluation was included.ResultsBetween 10 March 2015 and 31 March 2016, we recruited 414 people (intervention 208, usual care 206) with 341 (84.4%) participants completing the trial. At 12 months, weight reduction did not differ between groups (mean difference 0.0 kg, 95% CI −1.6 to 1.7, P = 0.963); physical activity, dietary intake and biochemical measures were unchanged. STEPWISE was well-received by participants and facilitators. The healthcare perspective incremental cost-effectiveness ratio was £246 921 per quality-adjusted life-year gained.ConclusionsParticipants were successfully recruited and retained, indicating a strong interest in weight interventions; however, the STEPWISE intervention was neither clinically nor cost-effective. Further research is needed to determine how to manage overweight and obesity in people with schizophrenia.Declaration of interestR.I.G.H. received fees for lecturing, consultancy work and attendance at conferences from the following: Boehringer Ingelheim, Eli Lilly, Janssen, Lundbeck, Novo Nordisk, Novartis, Otsuka, Sanofi, Sunovion, Takeda, MSD.

A group of international experts in psychiatry, medicine, toxicology and pharmacy assembled to undertake a critical examination of the currently available clinical guidance on hyperprolactinaemia. This paper summarises the group's collective views and provides a summary of the recommendations agreed by the consensus group to assist clinicians in the recognition, clinical assessment, investigation and management of elevated plasma prolactin levels in patients being treated for severe mental illness. It also deals with the special problems of particular populations, gives advice about information that should be provided to patients, and suggests a strategy for routine monitoring of prolactin. The recommendations are based upon the evidence contained in the supplement 'Hyperprolactinaemia in schizophrenia and bipolar disorder: Clinical Implications' (2008). The guidance contained in this article is not intended to replace national guidance (such as that of the National Institute of Clinical Excellence), however, it does provide additional detail that is unlikely to be covered in existing guidelines, and focuses on areas of uncertainty and disagreement. We hope it will add to the debate about this topic.

BackgroundCardiometabolic disease is more common in patients with schizophrenia than the general population.AimThe purpose of the study was to assess lifestyle factors, including diet and exercise, in patients with schizophrenia and estimate the prevalence of metabolic syndrome.MethodsThis is a cross-sectional study of a representative group of outpatients with schizophrenia in Salford, UK. An interview supplemented by questionnaires was used to assess diet, physical activity, and cigarette and alcohol use. Likert scales assessed subjects’ views of diet and activity. A physical examination and relevant blood tests were conducted.ResultsThirty-seven people were included in the study. 92% of men had central adiposity, as did 91.7% of women (International Diabetes Federation Definition). The mean age was 46.2 years and mean illness duration was 11.6 years. 67.6% fulfilled criteria for the metabolic syndrome. The mean number of fruit and vegetable portions per day was 2.8 ± 1.8. Over a third did not eat any fruit in a typical week. 42% reported doing no vigorous activity in a typical week. 64.9% smoked and in many cigarette use was heavy. The Likert scale showed that a high proportion of patients had insight into their unhealthy lifestyles.ConclusionsWithin this sample, there was a high prevalence of poor diet, smoking and inadequate exercise. Many did not follow national recommendations for dietary intake of fruit and vegetables and daily exercise. These factors probably contribute to the high prevalence of metabolic syndrome. Many had insight into their unhealthy lifestyles. Thus, there is potential for interventions to improve lifestyle factors and reduce the risk of cardiometabolic disease.Electronic supplementary materialThe online version of this article (doi:10.1186/s12991-017-0134-6) contains supplementary material, which is available to authorized users.

Long-term weight management of obese and overweight patients with severe forms of mental illness was possible through the provision of simple lifestyle advice within the group setting.
