The STRIDE weight loss and lifestyle intervention for individuals taking antipsychotic medications: a randomized trial

The impact of a multimodal intervention on physical health factors and lifestyle in patients with affective disorders - results from a randomized controlled trial

Background

Traditional treatment for affective disorders primarily focuses on symptom management through pharmacotherapy and psychotherapy and rarely addresses co-existing physical impairments.

Methods

This randomized controlled trial assessed the impact of a six-month multimodal intervention (AWARE) on physical health in patients with bipolar and unipolar depressive disorders. A total of 103 patients, median age 40.75 years (65 % female), were randomized into the AWARE group (n = 50) or treatment as usual (TAU) group (n = 53). The AWARE intervention included five modules focused on activities of daily living, mood management, social relations, physical health, and cognition, with participants receiving approximately 12 sessions. TAU involved standard psychiatric care, Health outcomes were evaluated on sleep, metabolic markers, substance use, medication side effects, and perceived physical health. Statistical analyses used logistic regression for group comparisons and analysis of covariance for continuous outcomes.

Results

The AWARE group had significant improvements in sleep onset latency and reported reduced physical pain affecting daily work compared to TAU. However, no statistically significant differences were found in other physical health outcomes, such as metabolic markers, substance use, medication side effects, or perceived physical health. Study limitations include a modest sample size and a relatively short intervention duration.

Conclusion

While the AWARE intervention improved sleep and pain management, it did not significantly affect other health markers. Future research should involve longer intervention periods, larger sample sizes, and a comprehensive approach to both mental and physical health.

Psychosocial hybrid interventions for weight and sedentary behavior management among patients with severe mental disorders: A systematic review and meta-analysis

BACKGROUND

Severe mental disorders, such as schizophrenia, bipolar disorders, and other psychosis have been associated with risk of premature mortality, predominantly due to cardiovascular diseases and metabolic syndrome. The aim of this systematic review and meta-analysis was to examine the efficacy of hybrid psychosocial interventions combining face-to-face and eHealth components for patients with severe mental disorders on reduction of weight and waist circumference.

METHOD

The electronic search on PubMED, PsycINFO, EMBASE, Web of Science were conducted, and data were extracted twice. A supplementary search was also conducted. Interventions with severe mental disorder patients reporting outcomes related to obesity, metabolism, metabolic syndrome, and inflammation were included. Data were synthesized using a systematic narrative synthesis framework, and formal quality assessments to address the risk of bias. A meta-analysis was also conducted.

RESULTS

After following the steps recommended by PRISMA statements, 14 studies were included in the systematic review and four studies were included in meta-analysis. The pooled analysis demonstrated that hybrid interventions were not able to significantly promote waist circumference changes [SMD (cm) = -0.19, 95% CI = -0.60, 0.22; Z = 0.91; p = 0.36; two studies] nor weight reduction [SMD (kg) = -0.21, 95% CI = -0.43, 0.01; Z = 1.90; p = 0.06; four studies] in patients with severe mental disorders.

CONCLUSION

More studies should focus on hybrid mental health psychosocial for weight control and sedentary lifestyle need to be elaborated to verify their effectiveness in improving sedentary lifestyle and promoting weight reduction in people with severe mental disorders.

Risk factors, prevention and treatment of weight gain associated with the use of antidepressants and antipsychotics: a state-of-the-art clinical review

INTRODUCTION

People with severe mental illness have poor cardiometabolic health. Commonly used antidepressants and antipsychotics frequently lead to weight gain, which may further contribute to adverse cardiovascular outcomes.

AREAS COVERED

We searched MEDLINE up to April 2023 for umbrella reviews, (network-)meta-analyses, trials and cohort studies on risk factors, prevention and treatment strategies of weight gain associated with antidepressants/antipsychotics. We developed 10 clinical recommendations.

EXPERT OPINION

To prevent, manage, and treat antidepressant/antipsychotic-related weight gain, we recommend i) assessing risk factors for obesity before treatment, ii) monitoring metabolic health at baseline and regularly during follow-up, iii) offering lifestyle interventions including regular exercise and healthy diet based on patient preference to optimize motivation, iv) considering first-line psychotherapy for mild-moderate depression and anxiety disorders, v)choosing medications based on medications' and patient's weight gain risk, vi) choosing medications based on acute vs long-term treatment, vii) using effective, tolerated medications, viii) switching to less weight-inducing antipsychotics/antidepressants where possible, ix) using early weight gain as a predictor of further weight gain to inform the timing of intervention/switch options, and x) considering adding metformin or glucagon-like peptide-1 receptor agonists, or topiramate(second-line due to potential adverse cognitive effects) to antipsychotics, or aripiprazole to clozapine or olanzapine.

Orlistat for the treatment of antipsychotic-induced weight gain: an eight-week multicenter, randomized, placebo-controlled, double-blind trial

BACKGROUND

Weight gain and metabolic disorders are commonly induced by antipsychotics. Orlistat is a lipase inhibitor used for weight control. The effect of orlistat on weight gain and metabolic disturbances in people (especially women) treated with antipsychotics has not been sufficiently studied. This study aimed to investigate the efficacy of orlistat in mitigating antipsychotic-induced weight gain and abnormal glycolipid metabolism.

METHODS

Patients with schizophrenia or bipolar disorder with a weight gain ≥ 7% after taking antipsychotics were recruited. Participants were randomly allocated to two groups: one received eight weeks of orlistat (360 mg/day) and the other received a placebo. Anthropometric and fasting serum biochemical parameters were measured at baseline, week 4 and week 8.

RESULTS

Sixty individuals (orlistat:placebo = 32:28) participated in the study. After controlling for the study center, the eight-week changes in body mass index (BMI), cholesterol (CHOL), high-density lipoprotein cholesterol (HDL-CH) and low-density lipoprotein cholesterol (LDL-CH) were significantly different between the groups. According to the mixed linear models, CHOL and LDL-CH were significantly lower in the orlistat group than in the control group at week 8. The week 0-to-8 slopes of BMI, CHOL and LDL-CH were also significantly lower in the orlistat group.

CONCLUSIONS

These findings suggested that orlistat is an effective intervention for attenuating weight gain and serum lipid disturbances in antipsychotic-treated patients.

Effectiveness of lifestyle intervention on prevention/management of antipsychotic-induced weight gain among persons with severe mental illness: A systematic review and meta-analysis

Individualized lifestyle interventions using motivational interviewing (MI) approach are recommended for persons with severe mental illness (SMI) for effective weight management. The aim of this meta-analysis was to assess the effectiveness of various lifestyle interventions that addressed obesity among persons with SMI. Twelve RCTs were assessed by individual reviewers using revised cochrane risk-of-bias tool (RoB 2). The standardized mean difference (SMD) was calculated with a 95% CI. The age of participants was between 18 and 70 years. Waist circumference showed an SMD of -0.09 (-0.22, 0.03), weight -0.03 (-0.10, 0.15) and BMI -0.07 (-0.07, 0.22). The findings in this meta-analysis revealed that though lifestyle interventions were statistically insignificant in reducing antipsychotic induced weight gain among persons with SMI, they show changes in intervention group. Psychosocial management along with lifestyle interventions, and MI are effective in the management of antipsychotic induced weight gain.

A review on side effect management of second-generation antipsychotics to treat schizophrenia: a drug safety perspective

INTRODUCTION

Effective side effects management present a challenge in antipsychotic treatment with second-generation antipsychotics (SGAs). In recent years, most of the commonly used SGAs, except for clozapine, have been shown to differ only slightly in their effectiveness, but considerably regarding perceived side effects, safety profiles, and compatibility to preexisting medical conditions.

AREAS COVERED

The current state of available evidence on side-effect management in SGA treatment of patients with schizophrenia spectrum disorders (SSD) is reviewed. In addition, current guideline recommendations are summarized, highlighting evidence gaps.

EXPERT OPINION

SGA safety and side effects needs to be considered in treatment planning. Shared decision-making assistants (SDMA) can support patients, practitioners and relatives to orient their decisions toward avoiding side effects relevant to patients' adherence. Alongside general measures like psychosocial and psychotherapeutic care, switching to better tolerated SGAs can be considered a relatively safe strategy. By contrast, novel meta-analytical evidence emphasizes that dose reduction of SGAs can statistically increase the risk of relapse and other unfavorable outcomes. Further, depending on the type and severity of SGA-related side effects, specific treatments can be used to alleviate induced side effects (e.g. add-on metformin to reduce weight-gain). Finally, discontinuation should be reserved for acute emergencies.

Lifestyle Coaching May Be an Effective Treatment for Schizophrenia

This commentary critiques the Danish CHANGE trial, which evaluated 3 levels of outpatient intervention intensity, in a group of outpatients with obesity and schizophrenia. Neither adding care coordination with weekly nurse contacts alone nor combining this treatment with assertive community lifestyle coaching as compared to treatment as usual improved outcomes, which included cardiovascular disease risk calculation, cardiorespiratory fitness, weight, and self-reported behaviors such as smoking, physical activity, and diet. The CHANGE trial investigators appear strongly averse to recommending the development and implementation of lifestyle medicine programs as a major component when treating outpatients with severe mental disorders. The potential dismissal of lifestyle medicine as a component of treatment for severe mental disorders is problematic. Valuable lessons can be learned from more thoroughly analyzing secondary outcomes such as medical and psychiatric hospitalization rates and total health care cost. The CHANGE trial data analysis needs to be expanded beyond the focus on changes in weight and serum cholesterol. Insulin resistance and high refined carbohydrate intake may be major factors in determining both the medical and psychiatric clinical course of schizophrenia. Assertive community lifestyle coaching is a novel treatment modality. Evidence strongly suggests assertive community lifestyle coaching substantially decreases both psychiatric and medical hospitalization rates.

General somatic health and lifestyle habits in individuals with obsessive- compulsive disorder: an international survey

BACKGROUND

Obsessive-compulsive disorder (OCD) has been associated with a broad range of health-related issues. Unhealthy lifestyle habits such as physical inactivity, an unhealthy diet, smoking, and alcohol consumption are hypothesized to contribute to this association. However, the lifestyle habits of individuals with OCD have been scarcely investigated. In this international survey, we explored the physical health and lifestyle habits of adults with a self-reported diagnosis of OCD.

METHODS

An online global survey available in seven languages was disseminated through interest organizations and social media between July 2021 and March 2022. The survey included questions relating to socio-demographic variables and clinical characteristics (including OCD symptom severity - as measured with the 12-item self-report scale Obsessive-Compulsive Inventory [OCI-12] - and psychotropic medication), physical health, and lifestyle habits. Frequencies and percentages, or means and standard deviations, as appropriate, were calculated. Subgroup analyses by OCD symptom severity, gender, and age group were performed.

RESULTS

A total of 496 individuals with OCD completed the survey and were included in the analyses (mean age = 36.0 years, SD = 12.5, range 18-79; 78.8% women). Most participants were from Europe (n = 245, 49.4%) and North America (n = 187, 37.7%). OCD symptom severity scores were on the moderate range (OCI-12 mean score = 21.2, SD = 9.1). A majority (n = 354, 71.4%) reported having comorbid somatic health issues, mainly allergies, gastrointestinal conditions, and cardiometabolic conditions. Nearly half of the sample (n = 236, 47.6%) reported a body mass index ≥ 25, corresponding to at least overweight. A significant proportion of the participants reported low physical activity (n = 271, 55.0%), unhealthy dietary habits (n = 182, 36.7%), risk consumption of alcohol (n = 111, 22.3%), and non-restorative sleep (n = 268, 54.0%). Subgroup analyses showed overall similar results across groups, with some exceptions.

CONCLUSIONS

In this sample, individuals with OCD self-reported a range of health-related issues and a number of unhealthy lifestyle behaviors, most prominently a lack of physical activity. Interventions aimed at modifying unhealthy lifestyles to prevent or improve health conditions beyond the psychiatric symptoms should be considered.

Factors influencing engagement in in-person and remotely delivered lifestyle interventions for young adults with serious mental illness: A qualitative study

AIM

Young adults (ages 18-35) are underrepresented in lifestyle interventions for people with serious mental illness (SMI), such as schizophrenia, bipolar disorder, and severe depression, and little is known about factors influencing their engagement in these programmes. This qualitative study examined factors affecting engagement amongst young adults with SMI who were enrolled in a lifestyle intervention trial at community mental health centres.

METHODS

Seventeen young adults with SMI participated in this qualitative study. Participants were drawn from a 12-month randomized controlled trial (n = 150) comparing an in-person group lifestyle intervention augmented with mobile health technology (PeerFIT) to one-on-one personalized remote health coaching (BEAT) using purposive sampling. The 17 participants completed semi-structured qualitative interviews at post-intervention to explore their perceived benefits of the intervention and factors impacting engagement. We used a team-based descriptive qualitative approach to code transcripts and identify themes in the data.

RESULTS

Participants across both interventions reported experiencing improved ability to engage in health behaviour change. Participants described managing psychosocial stressors and family and other responsibilities that limited their ability to attend in-person PeerFIT sessions. The remote and flexible BEAT remote health coaching intervention appeared to facilitate engagement even in the context of challenging life circumstances.

CONCLUSIONS

Remotely delivered lifestyle interventions can facilitate engagement amongst young adults with SMI navigating social stressors.

Effectiveness of lifestyle interventions for improving the physical health of children and adolescents taking antipsychotic medications: protocol for a systematic review and meta-analysis

INTRODUCTION

Children and adolescents are increasingly prescribed antipsychotic medications off-label in the treatment of behavioural disorders. While antipsychotic medications are effective in managing behavioural issues, they carry a significant risk of adverse events that compromise ongoing physical health. Of particular concern is the negative impact antipsychotic medications have on cardiometabolic health. Interventions that aim to modify lifestyle habits have the potential to alleviate the adverse effects of antipsychotic medication by enhancing weight management, increasing physical activity, promoting better nutritional practices, improving dietary habits and promoting healthier sleep patterns and sleep hygiene. However, a comprehensive review has not been performed to ascertain the effectiveness of lifestyle interventions for children and adolescents who are at increased risk of antipsychotic-induced compromises to their physical health.

METHODS AND ANALYSIS

This systematic review will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Four databases will be searched without any year constraints to identify randomised controlled trials that are published in the English language and report a lifestyle intervention compared with usual care with any physical health outcome measure. Trial registers and results repositories will be scoured to identify additional studies. Two reviewers will independently conduct screening, data extraction and quality assessment and compare the results. Quantitative data will be synthesised, where appropriate, through a random-effects meta-analysis model. Otherwise, data will be reported in a qualitative (narrative) synthesis. Heterogeneity will be quantified using the I2 statistic. The Cochrane Risk of Bias 2 tool will be used for risk of bias assessment. The Grading of Recommendations, Assessment, Development and Evaluation system will be used to evaluate the cumulative body of evidence.

ETHICS AND DISSEMINATION

Ethics approval is not required. The publication plan will target high-impact, peer-reviewed journals that fall under the scope of Psychiatry and Mental Health.

The nurse-led GILL eHealth intervention for improving physical health and lifestyle behaviours in clients with severe mental illness: design of a cluster-randomised controlled trial

BACKGROUND

Clients with severe mental illness (SMI) have overall poor physical health. SMI reduces life expectancy by 5-17 years, primarily due to physical comorbidity linked to cardiometabolic risks that are mainly driven by unhealthy lifestyle behaviours. To improve physical health in clients with SMI, key elements are systematic somatic screening and lifestyle promotion. The nurse-led GILL eHealth was developed for somatic screening and the implementation of lifestyle activities in clients with SMI. Aims of this study are to evaluate the effectiveness of the GILL eHealth intervention in clients with SMI compared to usual care, and to evaluate the implementation process, and the experiences of clients and healthcare providers with GILL eHealth.

METHODS

The GILL study encompasses a cluster-randomised controlled trial in approximately 20 mental health care facilities in the Netherlands. The randomisation takes place at the team level, assigning clients to the eHealth intervention or the usual care group. The GILL eHealth intervention consists of two complementary modules for somatic screening and lifestyle promotion, resulting in personalised somatic treatment and lifestyle plans. Trained mental health nurses and nurse practitioners will implement the intervention within the multidisciplinary treatment context, and will guide and support the participants in promoting their physical health, including cardiometabolic risk management. Usual care includes treatment as currently delivered, with national guidelines as frame of reference. We aim to include 258 clients with SMI and a BMI of 27 or higher. Primary outcome is the metabolic syndrome severity score. Secondary outcomes are physical health measurements and participants' reports on physical activity, perceived lifestyle behaviours, quality of life, recovery, psychosocial functioning, and health-related self-efficacy. Measurements will be completed at baseline and at 6 and 12 months. A qualitative process evaluation will be conducted alongside, to evaluate the process of implementation and the experiences of clients and healthcare professionals with GILL eHealth.

DISCUSSION

The GILL eHealth intervention is expected to be more effective than usual care in improving physical health and lifestyle behaviours among clients with SMI. It will also provide important information on implementation of GILL eHealth in mental health care. If proven effective, GILL eHealth offers a clinically useful tool to improve physical health and lifestyle behaviours.

Effectiveness of a Lifestyle Intervention for People With a Severe Mental Illness in Dutch Outpatient Mental Health Care: A Randomized Clinical Trial

Importance

People with a severe mental illness (SMI) have a life expectancy reduced by 10 to 20 years compared with the general population, primarily attributable to cardiometabolic disorders. Lifestyle interventions for people with SMI can improve health and reduce cardiometabolic risk.

Objective

To evaluate the effectiveness of a group-based lifestyle intervention among people with SMI in outpatient treatment settings compared with treatment as usual (TAU).

Design, Setting, and Participants

The Severe Mental Illness Lifestyle Evaluation (SMILE) study is a pragmatic cluster randomized clinical trial performed in 8 mental health care centers with 21 flexible assertive community treatment teams in the Netherlands. Inclusion criteria were SMI, age of 18 years or older, and body mass index (calculated as weight in kilograms divided by height in meters squared) of 27 or greater. Data were collected from January 2018 to February 2020, and data were analyzed from September 2020 to February 2023.

Interventions

Weekly 2-hour group sessions for 6 months followed by monthly 2-hour group sessions for another 6 months, delivered by trained mental health care workers. The intervention targeted overall lifestyle changes, emphasizing establishing a healthy diet and promoting physical activity. TAU (control) did not include structured interventions or advice on lifestyle.

Main Outcomes and Measures

Crude and adjusted linear mixed models and multivariable logistic regression analyses were performed. The main outcome was body weight change. Secondary outcomes included changes in body mass index, blood pressure, lipid profiles, fasting glucose level, quality of life, self-management ability, and lifestyle behaviors (physical activity and health, mental health, nutrition, and sleep).

Results

The study population included 11 lifestyle intervention teams (126 participants) and 10 TAU teams (98 participants). Of 224 included patients, 137 (61.2%) were female, and the mean (SD) age was 47.6 (11.1) years. From baseline to 12 months, participants in the lifestyle intervention group lost 3.3 kg (95% CI, -6.2 to -0.4) more than those in the control group. In the lifestyle intervention group, people with high attendance rates lost more weight than participants with medium and low rates (mean [SD] weight loss: high, -4.9 [8.1] kg; medium, -0.2 [7.8] kg; low, 0.8 [8.3] kg). Only small or no changes were found for secondary outcomes.

Conclusions and Relevance

In this trial, the lifestyle intervention significantly reduced weight from baseline to 12 months in overweight and obese adults with SMI. Tailoring lifestyle interventions and increasing attendance rates might be beneficial for people with SMI.

Sports Therapy for Schizophrenia Psychoses: from the Idea to the Guideline

Schizophrenia psychoses can be treated much better today due to the introduction of antipsychotics about 70 years ago in conjunction with the implementation of specific psychotherapies. However, current treatment options are still limited in the area of negative symptoms and disease-associated cognitive deficits. In the last 15 years, randomised controlled trials (RCTs) have been able to show that physical training and especially endurance training could represent a comprehensive complementary treatment approach and could lead to a significant improvement in positive, but especially also in negative symptoms and cognitive deficits. As a result, sports therapy for schizophrenia psychoses has found its way not only into the national treatment guidelines of the German Society for Psychiatry, Psychotherapy, Psychosomatics and Neurology (DGPPN), but also into European recommendations such as those of the European Psychiatric Association (EPA). With the introduction of the "Living guideline" format (here an update takes place at least once a year), a broader implementation in health care will be easier in the future. Based on a narrative review, this paper describes the process of implementing sports therapy for schizophrenia psychoses from its beginnings to its incorporation into guidelines and can be applied analogously to other forms of therapy.

Value of gym-based group exercise versus usual care for young adults receiving antipsychotic medication: study protocol for the multicenter randomized controlled Vega trial

BACKGROUND

Exercise is recommended to protect physical health among people with severe mental illness and holds the potential to facilitate long-term recovery. An inclusive exercise community provides an opportunity for life skill training and social connectedness and may reduce the experience of loneliness and internalized stigmatization which together may improve personal recovery. Using a pragmatic randomized design, we aim to examine the effectiveness of a gym-based exercise intervention tailored to young adults in antipsychotic treatment (i.e., Vega Exercise Community) compared to usual care. It is hypothesized that the Vega Exercise Community will be superior to usual care for personal recovery at four months.

METHODS

The trial will be conducted at four sites in Denmark from which 400 participants, aged 18 to 35 years, who are in current treatment with antipsychotic medications for the management of schizophrenia spectrum or affective disorders, will be recruited. Participants will be randomized (2:1) to Vega Exercise Community or usual care. Vega Exercise Community includes three weekly group-based exercise sessions hosted in commercial functional training centers delivered by certified Vega instructors. After four months, participants in Vega Exercise Community will be randomized (1:1) to minimal versus extended support with regards to sustained physical activity. Data will be collected at baseline, four, six and 12 months. The primary outcome is personal recovery assessed by Questionnaire about the Process of Recovery at four months. Behavioral symptoms, health-related quality of life, metabolic health, and program costs will be evaluated to further determine the effectiveness and cost-effectiveness of the Vega Exercise Community. Finally, the quality of life and physical and mental health of the participants' primary relative will be evaluated.

DISCUSSION

The results of this trial may have important implications for health, sustained physical activity, and recovery for individuals in treatment with antipsychotics. Given the pragmatic design, positive results may readily be implemented by mental health care professionals to promote exercise as an integrated part of treatment of severe mental illness.

Effect of the GLP-1 receptor agonist semaglutide on metabolic disturbances in clozapine-treated or olanzapine-treated patients with a schizophrenia spectrum disorder: study protocol of a placebo-controlled, randomised clinical trial (SemaPsychiatry)

INTRODUCTION

Clozapine and olanzapine are some of the most effective antipsychotics, but both are associated with weight gain and relevant metabolic disturbances, including pre-diabetes and diabetes. Non-pharmacological/behavioural interventions have had limited effects counteracting these adverse effects. Semaglutide, a glucagon-like peptide 1 receptor agonist, is approved for the treatment of type 2 diabetes and obesity. We will investigate the long-term effects of add-on treatment with semaglutide once a week versus placebo once a week on the metabolic status in pre-diabetic (glycated haemoglobin A1c (HbA1c) 35-47 mmol/mol (5.4%-6.4%) and diabetic (HbA1c 48-57 mmol/mol (6.5%-7.4%)) patients diagnosed with a schizophrenia spectrum disorder who initiated clozapine or olanzapine treatment within the last 60 months.

METHODS AND ANALYSIS

This is a 26-week, double-blinded, randomised, placebo-controlled trial. Altogether, 104 patients diagnosed with a schizophrenia spectrum disorder, aged 18-65 years, with pre-diabetes or diabetes will be randomised to injections of 1.0 mg semaglutide once a week or placebo for 26 weeks. The primary endpoint is change from baseline in HbA1c. Secondary endpoints include changes in body weight, hip and waist circumference and plasma levels of insulin, glucagon, glucose, and C-peptide, insulin sensitivity, beta cell function, hepatic function, fibrosis-4 score, lipid profile, incretin hormones, bone markers, body composition, bone density, proteomic analyses and oxidative stress markers. Together with alcohol, tobacco and drug use, potential effects on the reward value of a sweet-fat stimulus, psychopathology, level of activity and quality of life will also be assessed.

ETHICS AND DISSEMINATION

This study is approved by the Danish Medicines Agency and the regional scientific ethics committee of the Capital Region of Denmark (committee C, #H-20019008) and will be carried out in accordance with International Council for Harmonisation Good Clinical Practice guidelines and the Helsinki Declaration. The results will be disseminated through peer-review publications and conference presentations.

Use of an Interactive Obesity Treatment Approach in Individuals With Severe Mental Illness: Feasibility, Acceptability, and Proposed Engagement Criteria

BACKGROUND

Digital and mobile health interventions are increasingly being used to support healthy lifestyle change, including in certain high-risk populations such as those with severe mental illnesses (SMIs). Life expectancy in this population lags 15 years behind counterparts in the general population, primarily due to obesity-related health conditions.

OBJECTIVE

We tested the feasibility and usability of a 12-week interactive obesity treatment approach (iOTA) to adults with chronic SMIs (depression, bipolar disorder and schizophrenia spectrum disorder) receiving treatment in community settings. The iOTA incorporates short message service (SMS) text messages to supplement monthly in-person health coaching.

METHODS

Factors hypothesized to be associated with weight change were illness severity and treatment engagement. Severe psychiatric symptoms were defined as baseline Clinical Global Impression severity score of >5. Criterion engagement was defined as a text messaging response rate >80% during the first 4 weeks of treatment. Disordered eating, assessed with the Loss of Control Over Eating Scores, was also evaluated. Participants provided qualitative data, further informing assessment of intervention feasibility, usability, and acceptability.

RESULTS

A total of 26 participants were enrolled. The mean age was 48.5 (SD 15.67) years; 40% (10/26) were Black and 60% (15/26) female. Participants with lower symptom severity and adequate engagement demonstrated significantly decreased weight (F1,16=22.54, P<.001). Conversely, high symptom severity and lower text message response rates were associated with trend-level increases in weight (F1,7=4.33, P=.08). Loss-of-control eating was not observed to impact treatment outcome. Participants voiced preference for combination of live health coaching and text messaging, expressing desire for personalized message content.

CONCLUSIONS

These results demonstrate the feasibility of delivering an adapted iOTA to SMI patients receiving care in community settings and suggest testable criteria for defining sufficient treatment engagement and psychiatric symptom severity, two factors known to impact weight loss outcomes. These important findings suggest specific adaptations may be needed for optimal treatment outcomes in individuals with SMI.

Virtual Learning Collaborative Compared to Technical Assistance as a Strategy for Implementing Health Promotion in Routine Mental Health Settings: A Hybrid Type 3 Cluster Randomized Trial

BACKGROUND

Despite widespread use of learning collaboratives, few randomized trials have evaluated their effectiveness as a strategy for implementing evidence based practices. This randomized trial evaluated the effectiveness of a virtual learning collaborative (VLC) in the implementation of a health promotion program for persons with serious mental illness (SMI) aimed at reducing cardiovascular risk reduction in routine mental health settings, compared to routine technical assistance (TA).

METHODS

Fifty-five mental health provider organizations were recruited to participate in a Hybrid Type 3 cluster randomized implementation-effectiveness trial of the InSHAPE health promotion program for persons with SMI. Sites were stratified by size and randomized prior to implementation to an 18-month group-based VLC with monthly learning sessions or individual site TA with four scheduled conference calls over 18 months. Primary implementation and service outcomes were InSHAPE program fidelity, participation, and reach. Primary clinical outcomes were weight loss, cardiorespiratory fitness, and cardiovascular risk reduction (≥ 5% weight loss or > 50 m increase on the 6-Minute Walk Test). Program fidelity was assessed at 6, 12, and 24 months; program participation and participant-level outcomes were assessed at 3, 6, 9, and 12 months.

RESULTS

VLC (N = 27) and TA (N = 28) sites were similar in organizational characteristics (all p > 0.05). At 12-month follow-up mean program fidelity score was higher in VLC compared to TA (90.5 vs. 79.1; p = 0.002), with over double the proportion with good fidelity (VLC = 73.9% vs. TA = 34.8%; p = 0.009). Over half of individuals in both VLC and TA achieved cardiovascular risk-reduction at 6-month follow-up (VLC: 51.0%; TA: 53.5%; p = 0.517) and at 12-month follow-up (62% VLC and TA; p = 0.912). At 12-month follow-up VLC compared to TA was associated with greater participation (VLC 69.5% vs. TA 56.4% attending at least 50% of sessions, p = 0.002); larger caseloads (VLC = 16 vs. TA = 11; p = 0.024); greater reach consisting of 45% greater number of participants receiving InSHAPE (VLC = 368 vs. TA = 253), and 58% greater number of participants achieving cardiovascular risk reduction (VLC = 150 vs. TA = 95).

CONCLUSION

Virtual learning collaboratives compared to routine technical assistance as an implementation strategy for evidence-based health promotion promote greater intervention fidelity, greater levels of intervention participation, greater reach, and a greater number of participants achieving clinically significant risk reduction outcomes, while achieving similarly high levels of intervention effectiveness for participants who completed at least 6 months of the program.

Impact of Moderating Demographic Variables on a Health Intervention for People with Serious Mental Illness

Purpose

Healthy lifestyle interventions can improve the health of people with serious mental illness (SMI). Little is known whether demographic variables moderate the effectiveness of these interventions on health outcomes.

Method

Data from an effectiveness trial of a peer-led healthy lifestyle intervention (PGLB) for people with SMI examine whether age, racial/ethnic minoritized status, and gender moderated the effectiveness of PGLB compared to usual care (UC) in achieving clinically significant improvements in weight, cardiorespiratory fitness, and cardiovascular disease (CVD) risk reduction.

Results

Compared to UC, PGLB was most beneficial for participants age 49 and younger for achieving clinically significant weight loss and from racial/ethnic minoritized communities for achieving clinically significant weight loss and reductions in CVD risk.

Conclusions

These findings suggest the impact of healthy lifestyle interventions for people with SMI may not be uniform and adaptations may be needed to make these interventions responsive to the needs of diverse populations.

Technology-enabled collaborative care for youth with early psychosis: Results of a feasibility study to improve physical health behaviours

AIM

Psychotic disorders are associated with excess morbidity and premature mortality. Contributing factors include tobacco smoking, low physical activity, and poor nutrition. This study tested a Technology-Enabled Collaborative Care model to improve health behaviours among youth with early psychosis.

METHODS

A feasibility study among youth (ages 16-29) with early psychosis in Ontario, Canada. Participants were randomized to either a health coach supervised by a virtual care team (high intensity, n = 29), or self-directed learning (low intensity, n = 23) for 12 weeks. The primary outcome was participant engagement, defined as self-perceived benefit of changing health behaviours. Secondary outcomes were measures of health behaviours and programme-use metrics.

RESULTS

Engagement was higher for high intensity participants for physical activity (adjusted group difference in change at 24 weeks = 3.4, CI95% = 1.9-4.9, p < .001) and nutrition (adjusted difference = 2.9, CI95% = 1.2-4.6, p = .001). No change was observed in health behaviours. Sixty two percent of participants completed 6 or more of the 12 weekly remote individualized health coaching sessions. Nine (39%) low intensity and 12 (41%) high intensity participants completed the final follow-up.

CONCLUSIONS

Personalized health coaching for youth with psychosis is feasible and may have sustained benefits. However, retention with this population for 12 weeks is challenging.

Effectiveness of nutrition and dietary interventions for people with serious mental illness: systematic review and meta-analysis

OBJECTIVE

To review recent published trials of nutrition and dietary interventions for people with serious mental illness; to assess their effectiveness in improving metabolic syndrome risk factors.

STUDY DESIGN

Systematic review and meta-analysis of randomised and non-randomised controlled trials of interventions with a nutrition/diet-related component delivered to people with serious mental illness, published 1 January 2010 - 6 September 2021. Primary outcomes were weight, body mass index (BMI), and waist circumference. Secondary outcomes were total serum cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol, triglyceride, and blood glucose levels.

DATA SOURCES

MEDLINE, EMBASE, PsycINFO, CINAHL, and CENTRAL databases. In addition, reference lists of relevant publications were examined for further additional studies.

DATA SYNTHESIS

Twenty-five studies encompassing 26 intervention arms were included in our analysis. Eight studies were at low or some risk of bias, seventeen were deemed to be at high risk. Eight of seventeen intervention arms found statistically significant intervention effects on weight, ten of 24 on BMI, and seven of seventeen on waist circumference. The pooled effects of nutrition interventions on metabolic syndrome risk factors were statistically non-significant. However, we identified small size effects on weight for interventions delivered by dietitians (five studies; 262 intervention, 258 control participants; standardised mean difference [SMD], -0.28; 95% CI, -0.51 to -0.04) and interventions consisting of individual sessions only (three studies; 141 intervention, 134 control participants; SMD, -0.30; 95% CI, -0.54 to -0.06).

CONCLUSIONS

We found only limited evidence for nutrition interventions improving metabolic syndrome risk factors in people with serious mental illness. However, they may be more effective when delivered on an individual basis or by dietitians.

Systematic review of lifestyle interventions to improve weight, physical activity and diet among people with a mental health condition

BACKGROUND

People with a mental health condition experience an elevated risk of chronic disease and greater prevalence of health and behaviours. Lifestyle interventions aim to reduce this risk by modifying health behaviours such as physical activity and diet. Previous reviews exploring the efficacy of such interventions for this group have typically limited inclusion to individuals with severe mental illness (SMI), with a focus of impact on weight. This review assessed the efficacy of lifestyle interventions delivered in community or outpatient settings to people with any mental health condition, on weight, physical activity and diet.

METHODS

Eligible studies were randomised or cluster-randomised controlled trials published between January 1999 and February 2019 aiming to improve weight, physical activity or diet, for people with any mental health condition. Two reviewers independently completed study screening, data extraction and assessment of methodological quality. Primary outcome measures were weight, physical activity and diet. Secondary outcome measures were body mass index (BMI), waist circumference, sedentary behaviour and mental health. Where possible, meta-analyses were conducted. Narrative synthesis using vote counting based on direction of effect was used where studies were not amenable to meta-analysis.

RESULTS

Fifty-seven studies were included (49 SMI only), with 46 contributing to meta-analyses. Meta-analyses revealed significant (< 0.05) effect of interventions on mean weight loss (-1.42 kg), achieving 5% weight loss (OR 2.48), weight maintenance (-2.05 kg), physical activity (IPAQ MET minutes: 226.82) and daily vegetable serves (0.51), but not on fruit serves (0.01). Significant effects were also seen for secondary outcomes of BMI (-0.48 units) and waist circumference (-0.87cm), but not mental health (depression: SMD -0.03; anxiety: SMD -0.49; severity of psychological symptoms: SMD 0.72). Studies reporting sedentary behaviour were not able to be meta-analysed. Most trials had high risk of bias, quality of evidence for weight and physical activity were moderate, while quality of evidence for diet was low.

CONCLUSION

Lifestyle interventions delivered to people with a mental health condition made statistically significant improvements to weight, BMI, waist circumference, vegetable serves and physical activity. Further high-quality trials with greater consistency in measurement and reporting of outcomes are needed to better understand the impact of lifestyle interventions on physical activity, diet, sedentary behaviour and mental health and to understand impact on subgroups.

Hybrid and Remote Psychosocial Interventions Focused on Weight and Sedentary Behavior Management Among Patients with Severe Mental Illnesses: a Systematic Review

Severe mental illness could be defined through its diagnosis, disability, and duration, and one of their main characteristics is the high prevalence of some clinical conditions such as obesity and metabolic syndrome. Although the promotion of a healthier lifestyle has been demonstrated as an effective strategy to reduce both body mass index and abdominal circumference in this population, there is a lack of studies focusing on digital intervention in this population. The aim of this systematic review was to evaluate the efficacy of studies that used digital technologies to reduce weight, body mass index (BMI) and abdominal circumference in individuals with severe mental illness. This current review also compared remote and hybrid interventions, the effects of those interventions in metabolic biomarkers as well as in the development of a healthier lifestyle. The main findings included the following: (a) the use of digital devices or strategies might be feasible and useful to reduce sedentary behavior among individuals with severe mental illnesses, 2) most interventions used digital pedometers and mobile phone communication (either text messages or phone calls) as main strategies, 3) all remote interventions and six of nine hybrid interventions found significant outcomes in favor of their interventions. In conclusion, even with a limited number of studies promoting healthier lifestyle through digital interventions among individuals with severe mental illnesses, evidence from studies included in this review showed that they might be useful to improve a healthier lifestyle and increase the frequency of physical activity behavior.

Correlates of Attendance in a Peer-Led Healthy Lifestyle Intervention for People with Serious Mental Illness Living in Supportive Housing

Healthy lifestyle interventions can improve the physical health of people with serious mental illness (SMI; e.g., schizophrenia). Yet, people with SMI report challenges participating in these interventions, thus limiting their potential benefits. This study examined attendance of participants (N = 155), largely comprised of racial and ethnic minorities, in a peer-led healthy lifestyle intervention living in supportive housing. A logistic regression model was used to identify correlates associated with attendance. Results indicated that females, those with at least a high school education, and a diagnosis of schizophrenia were more likely to attend. In contrast, the odds of attending at least one session were significantly lower for those who reported any drug use and for those who rated their health as good or excellent. Our findings indicate certain subgroups of people with SMI could benefit from tailored motivational strategies and supports to improve their participation in healthy lifestyle interventions. clinicaltrials.gov (NCT02175641).

Scaling Evidence-Based Interventions to Improve the Cardiovascular Health of People With Serious Mental Illness

People with serious mental illnesses (SMIs) experience excess mortality, driven in large part by high rates of cardiovascular disease (CVD), with all cardiovascular disease risk factors elevated. Interventions designed to improve the cardiovascular health of people with SMI have been shown to lead to clinically significant improvements in clinical trials; however, the uptake of these interventions into real-life clinical settings remains limited. Implementation strategies, which constitute the "how to" component of changing healthcare practice, are critical to supporting the scale-up of evidence-based interventions that can improve the cardiovascular health of people with SMI. And yet, implementation strategies are often poorly described and rarely justified theoretically in the literature, limiting the ability of researchers and practitioners to tease apart why, what, how, and when implementation strategies lead to improvement. In this Perspective, we describe the implementation strategies that the Johns Hopkins ALACRITY Center for Health and Longevity in Mental Illness is using to scale-up three evidenced-based interventions related to: (1) weight loss; (2) tobacco smoking cessation treatment; and (3) hypertension, dyslipidemia, and diabetes care for people with SMI. Building on concepts from the literature on complex health interventions, we focus on considerations related to the core function of an intervention (i.e., or basic purposes of the change process that the health intervention seeks to facilitate) vs. the form (i.e., implementation strategies or specific activities taken to carry out core functions that are customized to local contexts). By clearly delineating how implementation strategies are operationalized to support the interventions' core functions across these three studies, we aim to build and improve the future evidence base of how to adapt, implement, and evaluate interventions to improve the cardiovascular health of people with SMI.

Sleep quality and its relationship to mental health, physical health and health behaviours among young adults with serious mental illness enrolled in a lifestyle intervention trial

AIM

To characterize subjective sleep quality and examine its associations with mental health, physical health and health behaviours in a transdiagnostic sample of young adults with serious mental illness (SMI) enrolled in a lifestyle intervention trial.

METHODS

Baseline data from a lifestyle intervention trial with young adults (ages 18-35 years) with SMI included the Pittsburgh Sleep Quality Index (PSQI), mental health, physical health and health behaviour outcomes. Descriptive statistics and multiple linear regression were used in analyses.

RESULTS

Of 150 participants, 76% were categorized with poor sleep quality. Depressive symptoms were significantly associated with sleep quality (β = .438, p < .001); however, no association was found with physical health and health behaviours.

CONCLUSIONS

Young adults with SMI enrolled in lifestyle interventions may benefit from treatment that addresses sleep as part of a comprehensive approach to health promotion with attention to the role of depressive symptoms in sleep quality.

5:2 intermittent fasting tapers food intake in the refeeding state and ameliorates metabolic disturbances in mice exposed to olanzapine

A considerable number of patients suffer from adverse metabolic reactions caused by atypical antipsychotics (AAPs), however, current management strategies are disappointing to clinicians. Preclinical studies have consistently demonstrated that intermittent fasting (IF) has robust disease-modifying efficacy in animal models in a wide range of pathological conditions, especially obesity and diabetes. However, it is unclear what role IF can play in addressing AAPs-induced metabolic disturbances. In our study, we found that a 5:2 IF regimen significantly ameliorated the metabolic disturbances induced by olanzapine (a drug representative of AAPs) in animal models. Meanwhile, our research suggests that IF altering food intake during the refeeding phase may account for the metabolic benefit. This study provides supporting evidence regarding a potentially cost-effective intervention strategy for AAPs-induced metabolic disturbances.

Identifying effective characteristics of behavioral weight management interventions for people with serious mental illness: A systematic review with a qualitative comparative analysis

People with serious mental illness (SMI) have identified barriers to engaging in behavioral weight management interventions (BWMIs). We assessed whether BWMIs that addressed these barriers were more effective. First, we systematically reviewed qualitative literature and used a thematic analysis to identify the characteristics of BWMIs that promote engagement for adults with SMI. Second, we systematically reviewed randomized controlled trials (RCTs) of BWMIs in adults with SMI. Data on the characteristics that promoted engagement and weight outcomes were extracted. We then used a crisp-set qualitative comparative analysis (CsQCA) to identify which characteristics were associated with weight loss. For the qualitative review, 20 studies in 515 people with SMI were analyzed and nine characteristics were reported to promote engagement in BWMIs. For the systematic review, 34 RCTs testing 36 interventions in 4305 participants were included. The active interventions resulted in more weight loss (mean = -4.37 to +1 kg at 6 weeks to 18 months follow-up) compared with controls (-1.64 to +3.08 kg). The CsQCA showed BWMIs that offered regular contact, tools to support enactment, and tailored materials were associated with effectiveness. As these are all supplementary strategies, it may be possible to augment BWMIs available for the general population to engage people with SMI.

Improving the physical health of young people with early psychosis with lifestyle interventions: Scoping review

People with mental illness experience a shorter life expectancy compared to the general population. Poor physical health trajectory emerges following the onset of psychosis and is further compounded by the initiation of antipsychotic treatment. Young people are particularly at risk as the onset of mental illness mostly occurs between the age of 12 and 25 years. This represents a crucial period for early intervention to prevent a physical ill health trajectory. Furthermore, those who are at ultra-high risk for psychosis should also be targeted for early intervention. Lifestyle interventions have been identified as the first-line physical health promotion practice for improving the physical health of people with severe mental illness. The aim of this study was to conduct a scoping review following the JBI methodological guidance on scoping reviews to explore the current literature on lifestyle intervention trialled for early psychosis, including first-episode psychosis and those who are at ultra-high risk for psychosis. This review also explores the extent of literature examining physical health literacy in this specific population. The literature search was conducted on Medline, Embase, PsycINFO and Scopus. Twenty-two studies were included for the purpose of this scoping review, 21 of which examined the effects of lifestyle interventions and one of which reported on physical health literacy. This scoping review indicates the need for co-designed lifestyle interventions with the involvement of service users, families and carers and a focus on promoting physical health literacy, social support, and an incorporation of a health behaviour change model focus on promoting autonomous motivation. The findings of this study can inform future development of a novel co-designed lifestyle intervention for the targeted population.

Use of smartphones, mobile apps and wearables for health promotion by people with anxiety or depression: An analysis of a nationally representative survey data

People with mental illness have increased cardiovascular risk factors, which contributes significantly to mortality in this population. Digital interventions have emerged as promising models to promote physical health, although their potential for use in mental health populations is relatively unexplored. We examined the potential for using digital tools for health promotion by people with common mental disorders like anxiety or depression. Using data from the 2019 edition of the Health Information National Trends Survey (HINTS 5), we evaluated differences between individuals with self-reported history of diagnosed depression/anxiety and the general population with respect to ownership, usage, and perceived usefulness of digital tools for managing their health. Overall, individuals with anxiety or depression were as likely as the general population to use digital devices for their care. Those with anxiety or depression who had health apps were more likely to report intentions to lose weight than those without health apps. Significant sociodemographic predictors of digital tools usage included gender, age, income, and education level. People with anxiety or depression own and use digital health tools at similarly high rates to the general population, suggesting that these tools present a novel opportunity for health promotion among people with these disorders.

Renewed call for lifestyle interventions to address obesity among individuals with serious mental illness in the COVID-19 era and beyond

Behavioral health has the opportunity to lead the way in using lifestyle interventions to address obesity and health disparities in people with serious mental illness (SMI) in the COVID-19 era. Evidence-based interventions for weight loss in individuals with SMI exist, and the field has developed strategies for implementing these interventions in real-world mental health care settings. In addition to promoting weight loss, lifestyle interventions have the potential to address social isolation and loneliness and other patient-centered outcomes among individuals with SMI, which will be especially valuable for mitigating the growing concerns about loneliness attributed to the COVID-19 pandemic restrictions on in-person encounters. In this commentary, we discuss practice, policy, and research implications related to using evidence-based lifestyle interventions for individuals with SMI during the COVID-19 pandemic and sustaining these programs in the long-term.

Impact of Lurasidone and Other Antipsychotics on Body Weight: Real-World, Retrospective, Comparative Study of 15,323 Adults with Schizophrenia

Purpose

The primary objectives were to describe weight changes following initiation of lurasidone versus other antipsychotics and estimate the risk of clinically relevant (≥7%) weight changes.

Patients and Methods

This retrospective, longitudinal comparative cohort study was based on electronic medical records (EMRs) of United States (US) adult patients with schizophrenia who were prescribed lurasidone or other antipsychotics as monotherapy between 1 April 2013 and 30 June 2019.

Results

Overall, the study included 15,323 patients with a diagnosis of schizophrenia; 6.1% of patients received lurasidone, 60.4% received antipsychotics associated with a medium-high risk of weight gain (clozapine, olanzapine, quetiapine, risperidone, paliperidone) and 33.5% received antipsychotics with a low risk of weight gain (aripiprazole, first-generation antipsychotics, ziprasidone). Lurasidone was associated with the smallest proportion of patients experiencing clinically relevant weight gain and the greatest proportion of patients with clinically relevant weight loss. The risk of clinically relevant weight gain was numerically higher with all antipsychotics versus lurasidone and was statistically significant for olanzapine (hazard ratio [HR]=1.541; 95% confidence interval [CI]=1.121; 2.119; p=0.0078) versus lurasidone. The likelihood of ≥7% weight loss was significantly greater with lurasidone versus all antipsychotics (p<0.05), except ziprasidone.

Conclusion

This real-world study suggests that lurasidone has a lower risk of clinically relevant weight gain and a higher likelihood of clinically relevant weight loss than other commonly used antipsychotics.

Participant Experiences With a Peer-Led Healthy Lifestyle Intervention for People With Serious Mental Illness

OBJECTIVE

This study explored the experiences of individuals with serious mental illness who were predominantly Black, were living in supportive housing, and participated in the Peer-Led Group Lifestyle Balance (PGLB) intervention. The authors examined how participants engaged in the process of behavior change and applied intervention concepts.

METHODS

Focus groups and interviews with 63 participants explored their motivation for engaging with PGLB, challenges to behavior change, and how they integrated intervention strategies into their lives. Interviews were transcribed and analyzed with grounded theory.

RESULTS

A grounded model summarized the description of the cycle of behavior change and provided insight into participants' decision-making processes. Challenges to engaging in healthy lifestyle change were related to participants' general medical health, time constraints, lack of knowledge, difficulties breaking old habits and changing self-perceptions, mood state, and the social-physical environment. Participants applied many intervention strategies, such as addressing problematic social cues, contexts, and food associations; planning ahead; starting with smaller changes; portion control; food substitution; mindful eating; and integrating changes into their daily lives. They reported various behavior changes with respect to eating and physical activity and more limited shifts in self-monitoring.

CONCLUSIONS

Improving the health of people with serious mental illness will require expanding their access to healthy lifestyle interventions in community-based settings. The findings suggest that future interventions should expand support for self-monitoring, meal planning, tailored physical activity, and advocacy. Such interventions should also enhance participants' understanding of the corresponding impact of changes on weight loss and emphasize subjective wellness outcomes to maintain motivation.

Main Outcomes of a Peer-Led Healthy Lifestyle Intervention for People With Serious Mental Illness in Supportive Housing

OBJECTIVE

The effectiveness of the Peer-led Group Lifestyle Balance (PGLB) intervention, a 12-month manualized healthy lifestyle intervention delivered by peer specialists, was investigated in a sample of persons with serious mental illness who were overweight or obese and living in supportive housing.

METHODS

The authors randomly assigned 314 participants from three supportive housing agencies to PGLB or usual care, with assessments at baseline and 6, 12, and 18 months. Outcomes were clinically significant changes from baseline in weight (≥5% weight loss), cardiorespiratory fitness (CRF; increase of ≥50 meters in the 6-minute walk test), and cardiovascular disease (CVD) risk reduction (clinically significant weight loss or CRF improvement).

RESULTS

Most participants were from racial-ethnic minority groups (82%, N=255). The mean±SD baseline weight of this sample was 218.8±54.0 pounds, and the body mass index was 33.7±7.2. Compared with the usual care group, a larger proportion of the PGLB group achieved clinically significant changes in study outcomes at 12 and 18 months, but none of these changes was statistically significant. Outcomes differed by site: two sites reported no significant differences between the two groups, and one reported that PGLB significantly outperformed usual care on clinically significant weight loss at 18 months and CVD risk reduction at 6 and 12 months.

CONCLUSIONS

The null findings indicate that PGLB was not superior to usual care in helping participants achieve clinically significant changes in weight, CRF, and CVD risk reduction at 12 and 18 months. Questions remain regarding how PGLB works, for whom, and in which settings.

Minding metabolism: targeted interventions to improve cardio-metabolic monitoring across early and chronic psychosis

Background

Antipsychotics (APs) increase weight, metabolic syndrome, diabetes and cardiovascular disease. Guidelines recommend cardio-metabolic monitoring at initial assessment, at 3 months and then annually in people prescribed APs.

Aim

To determine the rates of cardio-metabolic monitoring in AP treated early and chronic psychosis and to assess the impact of targeted improvement strategies.

Methods

Medical records were reviewed in two cohorts of first-episode psychosis (FEP) patients before and after the implementation of a physical health parameter checklist and electronic laboratory order set. In a separate group of patients with chronic psychotic disorders, adherence to annual monitoring was assessed before and 3 months after an awareness-raising educational intervention.

Results

In FEP, fasting glucose (39% vs 67%, p=0.05), HbA1c (0% vs 24%, p=0.005) and prolactin (18% vs 67%, p=0.001) monitoring improved. There were no significant differences in weight (67% vs 67%, p=1.0), BMI (3% vs 10%, p=0.54), waist circumference (3% vs 0%, p=1.0), fasting lipids (61% vs 76% p=0.22) or ECG monitoring (67% vs 67%, p=1.0). Blood pressure (BP) (88% vs 57%, p=0.04) and heart rate (91% vs 65%, p=0.03) monitoring dis-improved. Diet (0%) and exercise (<15%) assessment was poor. In chronic psychotic disorders, BP monitoring improved (20% vs 41.4%, p=0.05), whereas weight (17.0% vs 34.1%, p=0.12), BMI (9.7% vs 12.1%, p=1.0), fasting glucose (17% vs 24.3%, p=0.58) and fasting lipids remained unchanged (17% vs 24.3%, p=0.58).

Conclusions

Targeted improvement strategies resulted in a significant improvement in a limited number of parameters in early and chronic psychotic disorders. Overall, monitoring remained suboptimal.

Voluntary physical activity protects against olanzapine-induced hyperglycemia

Olanzapine (OLZ) is used in the treatment of schizophrenia and a growing number of "off-label" conditions. Although effective in reducing psychoses, OLZ causes rapid impairments in glucose and lipid homeostasis. The purpose of this study was to investigate if voluntary physical activity via wheel running (VWR) would protect against the acute metabolic side effects of OLZ. Male C57BL/6J mice remained sedentary or were provided with running wheels overnight, before treatment with OLZ either at the beginning of the light cycle, or 7 or 24 h following the cessation of VWR. Prior VWR protected against OLZ-induced hyperglycemia immediately and 7 h following a bout of overnight wheel running. Protection against, hyperglycemia immediately following VWR was associated with increased insulin tolerance and an attenuated OLZ-induced increase in the serum glucagon:insulin ratio. The protective effect of VWR against OLZ-induced increases in hyperglycemia and glucagon:insulin ratio was maintained in high-fat fed, and AMPK β1-deficient mice, models which display a potentiated OLZ-induced increase in blood glucose. Repeated OLZ treatment did not impair VWR performance and protection against the acute effects of OLZ on blood glucose was present after 1 wk of daily OLZ treatment in mice given access to running wheels. In contrast to the effects on glucose metabolism, VWR, for the most part, did not impact OLZ-induced perturbations in lipolysis, liver triglyceride accumulation, or whole body substrate oxidation. Collectively, our findings demonstrate the efficacy of voluntary physical activity as an approach to protect against OLZ-induced impairments in glucose metabolism.NEW & NOTEWORTHY The antipsychotic medication olanzapine causes rapid and large increases in blood glucose. We demonstrate that a prior bout of voluntary overnight wheel running can protect against this harmful side effect and is likely mediated by reductions in olanzapine-induced increases in the circulating glucagon to insulin ratio. This study highlights the powerful effects of voluntary activity in conditions of treatment with antipsychotic medications.

Peripheral mechanisms of acute olanzapine induced metabolic dysfunction: A review of in vivo models and treatment approaches

Antipsychotic (AP) medications are associated with an increased risk for developing metabolic side effects including weight gain, dyslipidemia, hypertension, type 2 diabetes (T2D), and cardiovascular disease. Previous reviews have focused on the chronic metabolic side effects associated with AP use. However, an underappreciated aspect of APs are the rapid perturbations in glucose and lipid metabolism that occur with each dose of drug. The purpose of this narrative review is to summarize work examining the peripheral mechanisms of acute olanzapine-induced related metabolic disturbances. We also discuss recent studies that have attempted to elucidate treatment approaches to mitigate AP-induced impairments in fuel metabolism.

The Acceptability and Feasibility of Using Text Messaging to Support the Delivery of Physical Health Care in those Suffering from a Psychotic Disorder: a Review of the Literature

Those suffering with serious mental illness (SMI), such as psychotic disorders, experience life expectancy 15 years shorter than the general population. Cardiovascular disease is the biggest cause of death in those with psychotic disease and many risk factors may be limited by healthy lifestyle choices. Text messaging interventions represent mobile health (mHealth), a nascent way to deliver physical health care to those suffering with a psychotic disorder. This paper aims to review the literature on the feasibility of text messaging to support the delivery of physical health care in those with a psychotic disorder. A thorough electronic database literature review of Medline via Ovid, Embase, APA Psycinfo, Scopus, Cochrane and Web of Science was conducted. Articles were included if text messaging was used as an intervention targeting the physical health of patients with psychotic disorders. A final sample of 11 articles satisfied the eligibility criteria, of which, 3 were ongoing randomised controlled trials. Of the 8 completed trials, all demonstrated the promising feasibility of text messaging, assessed via quotes, conversation samples, response rates, questionnaires or directly based on physical results. 36% of studies analysed those with schizophrenia or schizoaffective disorder, 55% with SMI and 9% with schizophrenia and psychotic disorders, mood disorders or anxiety disorders. Text messaging was used as motivation or reminders (91%), service delivery (27%) or social support (27%) with studies targeting multiple themes simultaneously. This review highlights compelling evidence for the feasibility of text messaging for improvement of physical health in those suffering with psychotic disorders.

Dietary Approaches to Stop Hypertension (DASH) Diet and Blood Pressure Reduction in Adults with and without Hypertension: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

The Dietary Approaches to Stop Hypertension (DASH) diet is recognized as an effective dietary intervention to reduce blood pressure (BP). However, among randomized controlled trials (RCTs) investigating the DASH diet-mediated BP reduction, there are significant methodological and clinical differences. The purpose of this study was to comprehensively assess the DASH diet effect on BP in adults with and without hypertension, accounting for underlying methodological and clinical confounders. We systematically searched Medline and the Cochrane Collaboration Library databases and identified 30 RCTs (n = 5545 participants) that investigated the BP effects of the DASH diet compared with a control diet in hypertensive and nonhypertensive adults. Both random-effects and fixed-effect models were used to calculate the mean attained systolic BP (SBP) and diastolic BP (DBP) differences during follow-up. Subgroup and meta-regression analyses were also conducted. Compared with a control diet, the DASH diet reduced both SBP and DBP (difference in means: -3.2 mm Hg; 95% CI: -4.2, -2.3 mm Hg; P < 0.001, and -2.5 mm Hg; 95% CI: -3.5, -1.5 mm Hg; P < 0.001, respectively). Hypertension status did not modify the effect on BP reduction. The DASH diet compared with a control diet reduced SBP levels to a higher extent in trials with sodium intake >2400 mg/d than in trials with sodium intake ≤2400 mg/d, whereas both SBP and DBP were reduced more in trials with mean age <50 y than in trials of older participants. The quality of evidence was rated as moderate for both outcomes according to the Grading of Recommendations, Assessment, Development, and Evaluation approach. The adoption of the DASH diet was accompanied by significant BP reduction in adults with and without hypertension, although higher daily sodium intake and younger age enhanced the BP-lowering effect of the intervention. This meta-analysis was registered at www.crd.york.ac.uk/prospero as CRD42019128120.

Lifestyle Interventions for Weight Management in People with Serious Mental Illness: A Systematic Review with Meta-Analysis, Trial Sequential Analysis, and Meta-Regression Analysis Exploring the Mediators and Moderators of Treatment Effects

BACKGROUND

Serious mental illness (SMI) reduces life expectancy, primarily due to somatic comorbidity linked to obesity. Meta-analyses have found beneficial effects of lifestyle interventions in people with SMI and recommended their implementation to manage obesity.

OBJECTIVE

The objective of this systematic review was to assess the benefits and harms of individualized lifestyle interventions for weight in people diagnosed with SMI and to explore potential mediators and moderators of the effect.

METHODS

The protocol was registered at PROSPERO (CRD42016049093). Randomized clinical trials (RCTs) assessing the effect of individualized lifestyle interventions on weight management in people with SMI were included. Primary outcomes were differences in endpoint body mass index (BMI) and the proportion achieving clinically relevant weight loss (≥5%). Secondary outcomes included quality of life, cardiometabolic risk factors, and adverse effects.

RESULTS

We included 41 RCTs (n = 4,267). All trials were at high risk of bias according to the Cochrane Handbook for Systematic Reviews of Interventions. The experimental interventions reduced the mean difference in BMI by -0.63 kg/m2 (95% confidence interval [CI] = -1.02 to -0.23; p = 0.002; I2 = 70.7%) compared to the control groups. At postintervention follow-up (17 RCTs), the effect size remained similar but was no longer significant (BMI = -0.63 kg/m2; 95% CI = -1.30 to 0.04; p = 0.07; I2 = 48.8%). The risk ratio for losing ≥5% of baseline weight was 1.51 (95% CI = 1.07-2.13; p = 0.02) compared to the control groups. GRADE showed very low or low quality of evidence.

CONCLUSION

There is a statistically significant, but clinically insignificant, mean effect of individualized lifestyle interventions for weight reduction in people with SMI.

Motivational theory-based interventions on health of people with several mental illness: A systematic review and meta-analysis

Motivational theory-based interventions are known to be effective for increasing physical activity (PA) in the general population but their effects in people with severe mental illness are poorly understood. Therefore, we conducted a meta-analysis on the effect of these interventions on PA and cardiometabolic risk factors. A systematic search of randomized controlled trials through 6 databases was carried out from inception to March 2019. Analyses were conducted using random-effect models. Weighted mean difference (WMD) were used as effect size when outcomes had the same units, otherwise Hedge's g was used. Fourteen articles including 2128 participants were identified. Motivational theory-based interventions were effective in increasing PA (g = 0.27, 95%CI[0.03; 0.51], p = .003), reducing weight (WMD = -1.87 kg, 95%CI[-2.98; -0.76], p = .001), body mass index (WMD = -0.82 kg/m2, 95%CI[-1.23; -0.41], p = .009), waist circumference (WMD = -1.91 cm, 95%CI[-3.63; -0.18], p = .03) and fasting glucose (g = -0.17, 95%CI[-0.34; -0.001], p = .04). Larger effect sizes were found in interventions based on only one theoretical model of motivation. In conclusion, interventions using motivational theories are effective to improve PA levels and the cardiometabolic health profile of people with severe mental illness. Systematic review registration: CRD42018104445.

Psychosocial therapies in severe mental illness: update on evidence and recommendations

PURPOSE OF REVIEW

To provide an overview of the update of the evidence-based and consensus-based German S3 guideline on psychosocial therapies for severe mental illnesses (SMI), with particular attention to current developments and future research tasks.

RECENT FINDINGS

There has been a significant increase in studies on the effectiveness of psychosocial interventions in treatment of people with SMI. In the guideline a distinction is made between system-level interventions (e.g. multidisciplinary team-based psychiatric community care) and single-handed (nonteam-based) interventions (e.g. psychoeducation). Furthermore, principles of treatment (e.g. recovery-orientation) and self-help interventions (e.g. peer support) are addressed. The update of the guideline includes 33 recommendations and 12 statements. Compared with the first edition, there were upgrades in the recommendation of Supported Employment (A) and Supported Housing (A). Interventions such as peer support (B) and lifestyle interventions (A) were included for the first time. Developments are discussed in the context of most recent literature. Areas for further research are highlighted and fields for next updates such as antistigma interventions and supported parenting were identified.

SUMMARY

The present guideline offers an important opportunity to further improve health services for people with SMI. However, guideline implementation is challenging.

Effect of a Comprehensive Cardiovascular Risk Reduction Intervention in Persons With Serious Mental Illness: A Randomized Clinical Trial

IMPORTANCE

Persons with serious mental illness have a cardiovascular disease mortality rate more than twice that of the overall population. Meaningful cardiovascular risk reduction requires targeted efforts in this population, who often have psychiatric symptoms and cognitive impairment.

OBJECTIVE

To determine the effectiveness of an 18-month multifaceted intervention incorporating behavioral counseling, care coordination, and care management for overall cardiovascular risk reduction in adults with serious mental illness.

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial was conducted from December 2013 to November 2018 at 4 community mental health outpatient programs in Maryland. The study recruited adults with at least 1 cardiovascular disease risk factor (hypertension, diabetes, dyslipidemia, current tobacco smoking, and/or overweight or obesity) attending the mental health programs. Of 398 participants screened, 269 were randomized to intervention (132 participants) or control (137 participants). Data collection staff were blinded to group assignment. Data were analyzed on the principle of intention to treat, and data analysis was performed from November 2018 to March 2019.

INTERVENTIONS

A health coach and nurse provided individually tailored cardiovascular disease risk reduction behavioral counseling, collaborated with physicians to implement appropriate risk factor management, and coordinated with mental health staff to encourage attainment of health goals. Programs offered physical activity classes and received consultation on serving healthier meals; intervention and control participants were exposed to these environmental changes.

MAIN OUTCOMES AND MEASURES

The primary outcome was the change in the risk of cardiovascular disease from the global Framingham Risk Score (FRS), which estimates the 10-year probability of a cardiovascular disease event, from baseline to 18 months, expressed as percentage change for intervention compared with control.

RESULTS

Of 269 participants randomized (mean [SD] age, 48.8 [11.9] years; 128 men [47.6%]), 159 (59.1%) had a diagnosis of schizophrenia or schizoaffective disorder, 67 (24.9%) had bipolar disorder, and 38 (14.1%) had major depressive disorder. At 18 months, the primary outcome, FRS, was obtained for 256 participants (95.2%). The mean (SD) baseline FRS was 11.5% (11.5%) (median, 8.6%; interquartile range, 3.9%-16.0%) in the intervention group and 12.7% (12.7%) (median, 9.1%; interquartile range, 4.0%-16.7%) in the control group. At 18 months, the mean (SD) FRS was 9.9% (10.2%) (median, 7.7%; interquartile range, 3.1%-12.0%) in the intervention group and 12.3% (12.0%) (median, 9.7%; interquartile range, 4.0%-15.9%) in the control group. Compared with the control group, the intervention group experienced a 12.7% (95% CI, 2.5%-22.9%; P = .02) relative reduction in FRS at 18 months.

CONCLUSIONS AND RELEVANCE

An 18-month behavioral counseling, care coordination, and care management intervention statistically significantly reduced overall cardiovascular disease risk in adults with serious mental illness. This intervention provides the means to substantially reduce health disparities in this high-risk population.

Keeping the body in mind: A qualitative analysis of the experiences of people experiencing first-episode psychosis participating in a lifestyle intervention programme

The life expectancy gap experienced by people living with severe mental illness is primarily a result of cardiometabolic disease that is often exacerbated by side effects of antipsychotic medication. Commencement of atypical antipsychotic medication is commonly associated with weight gain. The Keeping the Body in Mind programme has demonstrated that early intervention with lifestyle activities can attenuate this weight gain and potentially improve long-term health outcomes. The aim of this study was to explore the experiences of young people who participated in the Keeping the Body in Mind programme, a targeted lifestyle intervention programme. A qualitative approach was used employing a semi-structured interview format. The interview schedule included questions related to four topics: aspects of the programmes that were useful, attributes of staff members that influenced the programme, changes in attitudes towards their own physical health, and suggestions for programme improvements. Interviews were recorded with duration ranging from 40 to 65 min. Thematic analysis was used to detect and assemble codes. These were then synthesized and classified into themes. Eleven participants were interviewed (seven males), aged between 18 and 25 years. Thematic analysis revealed four main themes: the role of physical health in mental health recovery; the importance of staff interactions; the value of peer interaction; and graduation to a sustainable healthy lifestyle. Study participants reported that they valued the programme for both their physical health and mental health recovery.

Efficacy of a Short Psychoeducational Group Intervention for the Prevention of Cardiovascular Risk in Patients With Severe Mental Disorder: A Randomized Trial

Psychoeducational interventions to improve healthy habits regarding cardiovascular risk (CVR) in people with a severe mental disorder showed scarce results in the literature. In this article, we showed the results of a randomized clinical trial including 80 adult outpatients (mainly psychosis spectrum) with moderate to very high CVR. A short-term psychoeducational group intervention to improve healthy habits regarding CVR was added to their as-usual individual psychoeducational schedule. With an intention-to-treat analysis, we expected improvements in the different parameters. Baseline and 1-year follow-up included CVR factors and indexes (REGICOR, SCORE, and DORICA). Basal characteristics did not show statistically significant differences between the groups. No significant improvements in any of the variables studied were observed in the intervention enriched group compared with the control individual group. Compliance with the sessions was scarce. The satisfaction with the intervention and the acquisition of knowledge were adequate. Moreover, the benefits of both interventions were weak.

Cost-effectiveness and budget impact of a lifestyle intervention to improve cardiometabolic health in patients with severe mental illness

Introduction

This study assessed the cost-effectiveness and budget impact of a lifestyle intervention to improve cardiometabolic health in severe mentally ill (SMI) patients in the LION trial.

Methods

Patients (n = 244) were randomized to receive either care-as-usual or a lifestyle intervention in which mental health nurses coached patients in changing their lifestyle by using a web tool. Costs and quality of life were assessed at baseline and at 6 and 12 months. Incremental costs per centimeter waist circumference (WC) lost and per Quality-Adjusted Life Year (QALY) gained were assessed. Budget impact was estimated based on three intervention-uptake scenarios using a societal and a third-party payer perspective.

Results

Costs and reduction in WC were higher in the intervention (n = 114) than in the control (n = 94) group after 12 months, although not statistically significant, resulting in €1,370 per cm WC lost. QALYs did not differ between the groups, resulting in a low probability of the intervention being cost-effective in cost/QALY gained. The budget impact analysis showed that for a reasonable participation of 43%, total costs were around €81 million over 5 years, or on average €16 million annually (societal perspective).

Conclusions

The intervention is not cost-effective at 12 months and the budget impact over 5 years is substantial. Possibly, 12 months was too short to implement the intervention, improve cardiometabolic health, and reduce care costs. Therefore, the incentive for this intervention cannot be found in short-term financial advantages. However, there may be benefits associated with lifestyle interventions in the long term that remain unclear.

The effectiveness of health behavior change interventions in managing physical health in people with a psychotic illness: A systematic review

PURPOSE

People living with psychotic illness disproportionately experience more comorbidities and have a markedly shorter life expectancy compared to the general population. This review evaluates the effectiveness of health behavior change interventions in improving health outcomes in this group.

DESIGN AND METHODS

All studies included objective physical health measures or health behaviors as the main outcome measures and experimental design with baseline and follow-up quantitative data. Only studies of moderate and strong quality were included. Narrative synthesis was undertaken.

FINDINGS

Included studies utilized a range of methodological designs and outcome measures. The majority reported significant intervention effect on most outcome measures.

PRACTICE IMPLICATIONS

Health behavior change interventions can be effective in improving health outcomes in people with psychotic illness, with the potential benefit of improved psychiatric outcomes.

Feasibility and Acceptability of a Student-Led Lifestyle (Diet and Exercise) Intervention Within a Residential Rehabilitation Setting for People With Severe Mental Illness, GO HEART (Group Occupation, Health, Exercise And Rehabilitation Treatment)

PURPOSE

People with severe mental illness (SMI) experience poor physical health and premature mortality, contributed significantly by modifiable lifestyle risk factors such as poor nutrition, low cardiorespiratory fitness, and physical inactivity. Lifestyle interventions can reduce cardiometabolic risk and confer a range of other positive mental and physical health benefits. We assessed the feasibility, acceptability, safety, and preliminary effectiveness of a lifestyle (combined dietary and exercise) intervention lead by senior exercise and dietetics students in a residential mental health rehabilitation setting.

DESIGN

Single arm, prospective study evaluating outcomes pre and post a 10-week dietary and exercise intervention.

METHOD

People with SMI from three residential rehabilitation units participated in a mixed aerobic and resistance training exercise intervention three times per week that was combined with a dietary intervention (six individual and group sessions). Primary outcome considerations were feasibility (recruitment, retention, and participation rates), acceptability, and adverse events. Secondary outcomes were preliminary effectiveness; (functional exercise capacity, volume of exercise, and metabolic markers), psychiatric symptoms, quality of life, and attitudes to exercise.

RESULTS

Forty-two participants were recruited (92% primary diagnosis of schizophrenia). Intervention feasibility was supported by high levels of recruitment (68%), retention (77%), and participation (70% exercise, 65% diet sessions); and the absence of serious adverse events. Significant improvements in functional exercise capacity, volume of exercise, general psychiatric symptoms, and negative psychotic symptoms occurred. Anthropometric and metabolic blood markers did not change. While the intervention was acceptable to participants, motivation for and perceived value of exercise reduced over 10 weeks.

CONCLUSIONS

A brief pragmatic student-led lifestyle intervention integrated into usual mental health care was feasible, acceptable, safe, and scalable across two additional mental health residential rehabilitation sites, and resulted in physical and mental health improvements. Increased frequency of dietary sessions and length of dietary intervention may improve metabolic outcomes in the future. People with SMI living in residential rehabilitation units should have access to lifestyle programs to address modifiable lifestyle risk factors. While this brief intervention was feasible and acceptable, this study highlights some of the challenges associated with maintaining motivation for healthy lifestyles for people with SMI. Longer term investigation of real-world lifestyle interventions is warranted, together with additional interventions that may support people with SMI to sustain motivation to address lifestyle factors.

Effectiveness of a community-based nurse-led lifestyle-modification intervention for people with serious mental illness and metabolic syndrome

The development of metabolic syndrome negatively affects the quality of life of people with serious mental illness. Experts agree on the need to evaluate the physical health of patients and intervene in modifiable risk factors, with emphasis on the promotion of healthy lifestyles. Interventions should include nutritional counselling and physical activity. This 24-week randomized trial evaluated the effects of a community-based nurse-led lifestyle-modification intervention in people with serious mental illness meeting metabolic syndrome criteria, and its impact on health-related quality of life and physical activity. Sixty-one participants from two community mental health centres were randomly assigned to the intervention or control group. The intervention consisted of weekly group sessions, with 20 min of theoretical content and 60 min of nurse-led physical activity. Postintervention results between groups showed no differences in weight, waist circumference, fasting glucose, and systolic blood pressure. Differences in body mass index, triglyceride concentrations, and diastolic blood pressure were found to be significant (P = 0.010, P = 0.038, and P = 0.017). Participants who performed the intervention reported an increase in physical activity, which did not occur in the control group (P = 0.035), and also reported better health status (P < 0.001). Our intervention showed positive effects reducing participants' cardiovascular and metabolic risks and improving their physical activity and quality of life. To our knowledge, this is the first clinical trial led and carried out by mental health nurses in community mental health centres which takes into account the effects of a lifestyle intervention on every metabolic syndrome criterion, health-related quality of life, and physical activity.

Health Effects of an Individualized Lifestyle Intervention for People with Psychotic Disorders in Psychiatric Outpatient Services: A Two Year Follow-up

People with psychotic disorders experience to a great extent avoidable physical illnesses and early mortality. The aim of the study was to investigate the potential effects for this group of participating in a lifestyle intervention. A multi-component nurse-led lifestyle intervention using quasi-experimental design was performed. Changes in biomedical and clinical measurements, self-reported health, symptoms of illness and health behavior were investigated. Multilevel modeling was used to statistically test differences in changes over time. Statistically significant changes were found in physical activity, HbA1c and waist circumference. A lifestyle intervention for people with severe mental illness can be beneficial for increasing physical activity.

An appraisal of methodology reporting in lifestyle interventions among people with psychosis: A systematic review

ISSUE ADDRESSED

Lifestyle interventions use nutrition and physical activity behaviour modification techniques to decrease obesity and cardio-metabolic risk in people with psychosis. Evidence on the specific behaviour modification strategies applied to decrease obesity is weakened by inadequate methodology reporting of lifestyle interventions. A systematic review that we conducted earlier highlighted a possible deficiency in reporting; hence we aim to critically appraise lifestyle intervention studies that target weight outcomes for people with psychosis against the methods component of the CONSORT statement for randomised trials of nonpharmacologic treatments.

METHODS COMPONENT

We considered randomised controlled studies which delivered lifestyle interventions to community-dwelling adults with psychotic disorders, and included those with the following outcomes of interest: weight, body mass index, waist circumference and waist-to-hip ratio. The Cochrane Library, MEDLINE/PREMEDLINE, EMBASE, CINAHL, Scopus and PsycINFO were searched for English publications between 1985 and 2018. Methodology and reporting of studies were evaluated using the CONSORT statement for randomised trials of nonpharmacologic treatments.

RESULTS

Thirty-two studies met the inclusion criteria. Critical appraisals revealed that reporting of lifestyle intervention studies was generally incomplete. Fewer than 50% provided the recommended information on trial design, participant characteristics, detail of interventions, outcomes, sample size, randomisation, blinding and statistical methods.

CONCLUSIONS

Application of guidelines, like the CONSORT statement, in future publications of lifestyle interventions for people with psychosis will improve accuracy of reporting. SO WHAT?: Enhanced reporting in lifestyle intervention studies for people with psychosis will promote guideline creation and translation of research, which is likely to positively impact physical health outcomes.
