Physical health promotion in patients with functional psychoses receiving community psychiatric services: Results of the PHYSICO-DSM-VR study

Motiv8: a study protocol for a cluster-randomised feasibility trial of a weight management intervention for adults with severe mental illness in secure forensic services

INTRODUCTION

People with severe mental illness have physical comorbidities which result in significant reductions in quality of life and premature mortality. Effective interventions are required that are suitable for people in secure forensic mental health services. We conducted pilot work of a multidisciplinary weight management intervention (Motiv8) which showed improvements in physical and mental health and high levels of satisfaction. We aim to test the feasibility of Motiv8 under cluster randomised conditions, with an aim to investigate the acceptability, feasibility and potential effectiveness of this intervention to supplement standard secure care.

METHODS AND ANALYSIS

A randomised waitlist-controlled feasibility trial of a lifestyle intervention (Motiv8) + TAU compared with TAU (+ Motiv8 waitlist) for adults on secure mental health units will be conducted. Thirty-two people (4 cohorts) will be recruited from secure services in Greater Manchester Mental Health NHS Foundation Trust. Participants will be randomly allocated to Motiv8 or TAU + Motiv8 waitlist. All participants will receive Motiv8 during the trial. Assessor-blinded physical/mental health and lifestyle assessments will be conducted at baseline, 10 weeks (post-intervention/waitlist), and after 12 weeks (post-waitlist intervention/follow-up). Motiv8 is a multidisciplinary intervention including exercise sessions, cooking/nutrition classes, physical health education, psychology sessions, sleep hygiene, peer support and medication review by pharmacy. A nested qualitative study will be conducted with a subsample of participants (n = 10) to explore their experiences of taking part. The analysis will focus on feasibility outcomes and tabulated success indicators of the study (e.g. Recruitment rates, retention rates, follow-up retention and response rates, attendance at sessions, the experience of involvement in the trial and delivery of the intervention, assessment of safety, development of a manualised intervention). Thematic analysis will be conducted through qualitative interviews. The analysis will aim to inform the development of a definitive trial.

ETHICS AND DISSEMINATION

The trial has been granted ethical approval from the NHS Health Research Authority and adopted onto the UK Clinical Research Network Portfolio. Findings will be disseminated via peer-reviewed publications, professional and public networks, conferences and clinical services.

Improving physical activity and diet in patients with severe mental disorders: Results from the LIFESTYLE multicentric, real-world randomized controlled trial

Aims of the present study are to test the efficacy of a lifestyle group intervention, compared to a brief psychoeducational intervention, on levels of physical activity and dietary habits in a real-world sample of patients with severe mental disorders. The study, funded by the Italian Ministry of Education, has been carried out in six Italian University psychiatric outpatient units. All patients were randomly assigned to the experimental or control group and were assessed through standardized assessment instruments at baseline and six months after randomization. Of the 401 recruited patients, 43.3% had a diagnosis of bipolar disorder, 29.9% of psychosis and 26.9% of major depression. Patients were mainly female (57%), with a mean age of 45.6±11.8 years. Treated patients have almost 8 times the likelihood to show an increase of the total MET (OR: 8.02; p < .001) and of the walking MET (OR: 7.68; p < .001) and are more likely to increase the weekly consumption of vegetables (OR= 1.98, p < .05) and to reduce that of junk food (OR:0.23; p < .05). The present study support the notion that patients with severe mental disorders can improve their lifestyle behaviours and that, with appropriate support, they can achieve a healthy living.

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.

Engaging community-dwelling older adults as co-developers in a public outdoor exercise facilities-based physical activity education intervention: A mixed-method participatory study in Hong Kong

In Hong Kong, an increasing number of outdoor exercise facilities have been established in public open spaces to promote physical activity (PA) in older adults. However, no intervention is dedicated in educating the public on how to make use of these resources to fulfil the PA guidelines based on behavioural change theory. This study has two phases, phase one aims to describe the participatory development of the intervention, and phase two is the evaluation of a public outdoor exercise facilities-based PA education intervention for community-dwelling older adults. A mixed-methods participatory design was used to evaluate the impact of the intervention. PA behaviour was assessed as the fulfilment of the PA recommendations by World Health Organization, and the Rapid Assessment of Physical Activity (RAPA) scale at baseline, immediately, and 3 and 6 months post-intervention. Psychosocial constructs and physical assessments were carried out at both pre- and post-intervention. Individual in-depth interviews were conducted at post-intervention. Forty-seven participants were enrolled in the intervention. The average adherence rate was 90.87%. PA significantly increased after the intervention and remained elevated for the following 6 months. Post-intervention, the qualitative findings supported the quantitative findings at both the individual and social levels. However, findings regarding the change in participants' usage of environmental resources were divergent. The intervention was well-received by the participating older adults, as reflected by the high adherence rate. Both quantitative and qualitative data demonstrated the overall impacts of the intervention for creating sustainable changes in PA behaviour.

Patient-reported outcomes of lifestyle interventions in patients with severe mental illness: a systematic review and meta-analysis

BACKGROUND

Lifestyle interventions for severe mental illness (SMI) are known to have small to modest effect on physical health outcomes. Little attention has been given to patient-reported outcomes (PROs).

AIM

To systematically review the use of PROs and their measures, and quantify the effects of lifestyle interventions in patients with SMI on these PROs.

METHODS

Five electronic databases were searched (PubMed/Medline, Embase, PsycINFO, CINAHL, and Web of Science) from inception until 12 November 2020 (PROSPERO: CRD42020212135). Randomised controlled trials (RCTs) evaluating the efficacy of lifestyle interventions focusing on healthy diet, physical activity, or both for patients with SMI were included. Outcomes of interest were PROs.

RESULTS

A total of 11.267 unique records were identified from the database search, 66 full-text articles were assessed, and 36 RCTs were included, of which 21 were suitable for meta-analyses. In total, 5.907 participants were included across studies. Lifestyle interventions had no significant effect on quality of life (g = 0.13; 95% CI = - 0.02 to 0.27), with high heterogeneity (I² = 68.7%). We found a small effect on depression severity (g = 0.30, 95% CI = 0.00 to 0.58, I² = 65.2%) and a moderate effect on anxiety severity (g = 0.56, 95% CI = 0.16 to 0.95, I² = 0%).

DISCUSSION

This meta-analysis quantifies the effects of lifestyle interventions on PROs. Lifestyle interventions have no significant effect on quality of life, yet they could improve mental health outcomes such as depression and anxiety symptoms. Further use of patient-reported outcome measures in lifestyle research is recommended to fully capture the impact of lifestyle interventions.

Physical health interventions for patients who have experienced a first episode of psychosis: a narrative review

Objectives:

Service users with severe psychiatric illnesses, such as schizophrenia, major depressive disorder and bipolar disorder, are more likely to suffer from ill health. There is evidence that lifestyle interventions, for example, exercise, dietary advice and smoking cessation programmes for service users with severe mental illness can be of health benefit. This review was carried out to identify the literature pertaining to physical health interventions for service users who have experienced a first-episode psychosis (FEP), to examine the nature of the interventions which were carried out and to assess these interventions in terms of feasibility and efficacy.

Methods:

A narrative review was conducted in August 2019 by searching ‘Pubmed’ and ‘Embase’ electronic databases. Studies investigating the effect a physical health intervention had on service users who had experienced a FEP were included in the review.

Results:

Fifteen studies met inclusion criteria: 12 quantitative studies and 3 qualitative. Exercise, dietary advice, smoking cessation and motivational coaching were some of the physical health interventions utilised in the identified studies. Positive effects were seen in terms of physical health markers wherever they were investigated, particularly when the intervention was delivered early. The impact on psychiatric symptoms and longer-term impacts on health were less frequently assessed.

Conclusions:

Physical health interventions have a positive impact on service users who have experienced a FEP. More research is warranted in this area in Ireland. These studies should include controls, have longer follow-up periods and should assess the impact on psychiatric health.
