Primary care-based educational interventions to decrease risk factors for metabolic syndrome for adults with major psychotic and/or affective disorders: a systematic review

EPA guidance on lifestyle interventions for adults with severe mental illness: A meta-review of the evidence

There is growing interest in lifestyle interventions as stand-alone and add-on therapies in mental health care due to their potential benefits for both physical and mental health outcomes. We evaluated lifestyle interventions focusing on physical activity, diet, and sleep in adults with severe mental illness (SMI) and the evidence for their effectiveness. To this end, we conducted a meta-review and searched major electronic databases for articles published prior to 09/2022 and updated our search in 03/2024. We identified 89 relevant systematic reviews and assessed their quality using the SIGN checklist. Based on the findings of our meta-review and on clinical expertise of the authors, we formulated seven recommendations. In brief, evidence supports the application of lifestyle interventions that combine behavioural change techniques, dietary modification, and physical activity to reduce weight and improve cardiovascular health parameters in adults with SMI. Furthermore, physical activity should be used as an adjunct treatment to improve mental health in adults with SMI, including psychotic symptoms and cognition in adults with schizophrenia or depressive symptoms in adults with major depression. To ameliorate sleep quality, cognitive behavioural informed interventions can be considered. Additionally, we provide an overview of key gaps in the current literature. Future studies should integrate both mental and physical health outcomes to reflect the multi-faceted benefits of lifestyle interventions. Moreover, our meta-review highlighted a relative dearth of evidence relating to interventions in adults with bipolar disorder and to nutritional and sleep interventions. Future research could help establish lifestyle interventions as a core component of mental health care.

Effectiveness of dietary interventions in mental health treatment: A rapid review of reviews

AIM

This rapid review of reviews aimed to determine the extent of research undertaken on the effectiveness of dietary interventions for individuals with a mental disorder.

METHODS

Three databases (MEDLINE, Embase, Cochrane Reviews and Cochrane Trials) were searched to February 2021 for systematic reviews including experimental studies assessing the effectiveness of dietary interventions with physical or mental health related outcomes in adults or children with one or more of: severe mental illness, depression or anxiety, eating disorders, or substance use disorder. Results are presented descriptively.

RESULTS

The number of included reviews was 46 (67% in severe mental illness, 20% in depression and anxiety, 7% in eating disorders, and 7% in substance use disorders). Most reviews were published since 2016 (59%), and included studies conducted in adults (63%). Interventions in the eating disorders and severe mental illness reviews were predominantly education and behaviour change, whereas interventions in the substance use disorders, and depression and anxiety reviews were predominantly supplementation (e.g. omega-3). Twenty-eight and twelve of the reviews respectively reported mental health and dietary outcomes for one or more included studies. Most reviews in severe mental illness, and depression and anxiety reported conclusions supporting the positive effects of dietary intervention, including positive effects on weight-related or mental health outcomes, and on mental health outcomes, respectively.

CONCLUSIONS

A larger number of systematic reviews were identified which evaluated dietary interventions in individuals with severe mental illness, and depression and anxiety, compared with substance use disorders, and eating disorders. Dietary intervention is an important component of the treatment that should be available to individuals living with mental disorders, to support their physical and mental health.

Nonpharmacological Interventions for the Treatment of Cardiometabolic Risk Factors in People With Schizophrenia-A Systematic Review

Background: People suffering from schizophrenia are notably vulnerable to cardiometabolic risk factors (CMRF), such as obesity, high blood pressure, hyperglycemia and insulin resistance, high serum triglycerides, and low serum high-density lipoprotein (HDL), which are related to increased mortality and decreased quality of life. The increased risk of "metabolic syndrome" (MS) is related to low physical activity, an unhealthy diet, and side effects of antipsychotic drugs. Nonpharmacological interventions seem to be important in the prevention and therapy of MS. Aim: This paper provides an overview of published studies and a critical analysis of pilot programs involving nonpharmacological measures aimed at prevention and treatment of CMRF in patients with schizophrenia. Material and Method: We searched the PubMed, PsycARTICLES, and Cochrane Library databases to identify clinical trials. We included full-text studies that met the following criteria: age > 18 years, a diagnosis of schizophrenia or schizoaffective disorder, and monitored parameters associated with MS. Results: All 1,555 references were evaluated for inclusion in the review, and 20 met the inclusion criteria. Nonpharmacological interventions led to improvement in physical health and showed a promising potential for implementation in treatment programs dedicated to this particular group of patients. However, a critical analysis revealed limitations, which have implications for the direction of future research. Conclusions: Patients suffering from schizophrenia can benefit from nonpharmacological interventions aimed at counteracting CMRF, improving either metabolic parameters, cardiovascular fitness, or their health perception. Notwithstanding, to achieve long-term effects, future studies should comprise appropriate follow-up procedures.

The chasm of care: Where does the mental health nursing responsibility lie for the physical health care of people with severe mental illness?

The poor physical health of people with a severe mental illness is well documented and health professionals' attitudes, knowledge and skills are identified factors that impact on clients' access to care for their physical health needs. An evaluation was conducted to determine: (i) mental health nurses' attitudes and beliefs about providing physical health care; and, (ii) the effect that participant demographics may have on attitudes to providing physical health care. It was hypothesized that workplace culture would have the largest effect on attitudes. Nurses at three health services completed the "Mental health nurses' attitude towards the physical health care of people with severe and enduring mental illness survey" developed by Robson and Haddad (2012). The 28-item survey measured: nurses' attitudes, confidence, identified barriers to providing care and attitudes towards clients smoking cigarettes. The findings demonstrated that workplace culture did influence the level of physical health care provided to clients. However, at the individual level, nurses remain divided and uncertain where their responsibilities lie. Nursing leadership can have a significant impact on improving clients' physical health outcomes. Education is required to raise awareness of the need to reduce cigarette smoking in this client population.

Improving the physical health of people with severe mental illness in a low secure forensic unit: An uncontrolled evaluation study of staff training and physical health care plans

The life expectancy of people with severe mental illnesses is substantially reduced, and monitoring and screening for physical health problems is a key part of addressing this health inequality. Inpatient admission presents a window of opportunity for this health-care activity. The present study was conducted in a forensic mental health unit in England. A personal physical health plan incorporating clearly-presented and easily-understood values and targets for health status in different domains was developed. Alongside this, a brief physical education session was delivered to health-care staff (n = 63). Printed learning materials and pedometers and paper tape measures were also provided. The impact was evaluated by a single-group pretest post-test design; follow-up measures were 4 months' post-intervention. The feasibility and acceptability of personal health plans and associated resources were examined by free-text questionnaire responses. Fifty-seven staff provided measures of attitudes and knowledge before training and implementation of the physical health plans. Matched-pairs analysis indicated a modest but statistically-significant improvement in staff knowledge scores and attitudes to involvement in physical health care. Qualitative feedback indicated limited uptake of the care plans and perceived need for additional support for better adoption of this initiative. Inpatient admission is a key setting for assessing physical health and promoting improved management of health problems. Staff training and purpose-designed personalized care plans hold potential to improve practice and outcomes in this area, but further support for such innovations appears necessary for their uptake in inpatient mental health settings.

What Can Influence Iranian Suicide Attempters to Go Through the Process of Non-Fatal Suicide Act Once Again? A Preliminary Report

The thrust of this study was to examine some of the psycho-social risk factors for the recurrence of non-fatal suicide attempt in a sample of 1121 inmates admitted between April 2012 to June 2013 at the toxicology emergency ward, Noor Medical Centre, Isfahan, Iran. Out of the total participants, 240 of them reported history of suicide attempt and assumed the status of case group. The remaining 881 patients were admitted first their attempt and constituted the control group. Cases were compared to the controls with respect to select demographic features (i.e. age, sex, education, occupation, marital status, type of residence, and locale), current suicide attempt method, family history of suicide and drug abuse, history of psychiatric disorder, physical ailment and physical disability, substance abuse and alcohol use, psychiatric diagnosis, and recent life hassles (i.e. interpersonal, occupational, financial, medical, and home affairs). We used a structured interview schedule to interview the participants. Psychiatric diagnosis was based on the DSM-IV criteria. Data were computer analyzed using SPSS.21 and administering statistical analysis including Chi Square, t-student, and logistic regression. Demographic risk factors for recurrence of suicide attempts at the univariate level included occupational status [Crud odds Ratio (COR) = 0.53] and type of residence (COR = 1.40). Medical and psychiatric risk factors at the univariate level included substance abuse (COR = 1.97), physical ailment (COR = 1.76), alcohol use (COR = 1.84), psychiatric disorder (COR = 3.69), and history of suicide in the family of origin (COR = 1.86). Recent life hassles risk factors at the univariate level included financial constraints (COR = 1.46) and medical emergencies (COR = 3.48). A multivariate logistic regression model identified five variables (i.e. substance abuse, alcohol use, psychiatric illness, suicide in family, and medical emergencies) that were statistically associated with an increased risk for recurrence of nonfatal suicide attempt. The model predicted chances of repeating suicide attempt correctly 79 % of the time. These observations indicate that people who report to the toxicology emergency ward for nonfatal suicide not only need immediate relief but also careful psychiatric and social assessments which subsequently may lead to psychiatric admission and comprehensive community interventions.

Lifestyle interventions targeting dietary habits and exercise in bipolar disorder: A systematic review

BACKGROUND

Bipolar disorder (BD) is a serious mental illness associated with a high risk of medical comorbidities, long-term disability and premature death. This systematic review examined the current literature on therapeutic interventions targeting nutrition, physical activity and wellness in BD and collecting health-related measures such as mood and course of illness.

METHODS

Scopus (all databases), Pubmed and Ovid Medline were systematically searched with no language or year restrictions, up to June 2015, for studies focusing on lifestyle interventions in BD. Search terms were related to bipolar disorder, nutrition, physical activity, wellbeing, psychosocial interventions and course of illness. We hand searched content pages of Bipolar Disorders and Journal of Affective Disorders and checked references of relevant reviews and dissertations to identify additional papers.

RESULTS

After applying inclusion and exclusion criteria to identified hits, this literature search retrieved six papers. Overall findings point towards a beneficial role of lifestyle interventions on mood, weight, blood pressure, lipid profile, physical activity and overall wellbeing. Methodological limitations include small sample size, gender ratio imbalance, inconsistencies in terms of laboratory measures, and lack of randomized controlled trials and absence of follow-up and longitudinal studies to determine the benefits of these factors on clinical and functional outcomes over time

CONCLUSIONS

Lifestyle interventions in BD targeting nutrition, exercise, wellbeing alongside beliefs, coping strategies and attitudes towards health show promise in reducing the risk of comorbid ailments in BD. There is still a strong need for studies a) developing interventions which are informed by the patient's input and b) examining the effectiveness of such interventions targeting general wellness using well-controlled trials.

Schizophrenia in a Primary Care Setting

In recent years, the focus of mental health care for people with schizophrenia has shifted from an expectation of lifelong disability to a 'recovery' approach in which patients and specialists anticipate discharge to management within primary care. Although the active symptoms of mental illness are generally well-managed with modern pharmacotherapy, primary care physicians often express concern about their lack of understanding and expertise in general management of schizophrenia. Moreover, the ability of patients to access care for their physical disorders in a timely fashion together with a higher prevalence of physical co-morbidities is likely to be responsible for the greater mortality and premature death of this already stigmatised and disadvantaged group. This paper focuses on new evidence over the past 5 years, considering the management of physical and mental health of schizophrenia patients in primary care, optimal processes and the reasons why these may not always be realised in practice.

Can phone-based motivational interviewing improve medication adherence to antiplatelet medications after a coronary stent among racial minorities? A randomized trial

BACKGROUND

Minorities have lower adherence to cardiovascular medications and have worst cardiovascular outcomes post coronary stent placement

OBJECTIVE

The aim of this study is to compare the efficacy of phone-delivered Motivational Interviewing (MINT) to an educational video at improving adherence to antiplatelet medications among insured minorities.

DESIGN

This was a randomized study.

PARTICIPANTS

We identified minorities with a recently placed coronary stent from an administrative data set by using a previously validated algorithm.

INTERVENTIONS

MINT subjects received quarterly phone calls and the DVD group received a one-time mailed video.

MAIN MEASURES

Outcome variables were collected at baseline and at 12-month post-stent, using surveys and administrative data. The primary outcome was antiplatelet (clopidogrel and prasugrel) adherence measured by Medication Possession Ratio (MPR) and self- reported adherence (Morisky score). We also measured appropriate adherence defined as an MPR ≥ 0.80.

KEY RESULTS

We recruited 452 minority subjects with a new coronary stent (44 % Hispanics and 56 % Black). The patients had a mean age of 69.5 ± 8.8, 58 % were males, 78 % had an income lower than $30,000 per year and only 22 % had achieved high school education or higher. The MPR for antiplatelet medications was 0.77 for the MINT group compared to 0.70 for the DVD group (p < 0.05). The percentage of subjects with adequate adherence to their antiplatelet medication was 64 % in the MINT group and 50 % in the DVD group (p < 0.01). Self-reported adherence at 12 months was higher in the MINT group compared to the DVD group (p < 0.01). Results were similar among drug-eluting stent (DES) recipients.

CONCLUSIONS

Among racial minorities, a phone-based motivational interview is effective at improving adherence to antiplatelet medications post coronary stent placement. Phone-based MINT seems to be a promising and cost-effective strategy to modify risk behaviors among minority populations at high cardiovascular risk.

Leptin and the brain: influences on brain development, cognitive functioning and psychiatric disorders

Receptors of leptin, the prototypical adipokine, are expressed throughout the cortex and several other areas of the brain. Although typically studied for its role in energy intake and expenditure, leptin plays a critical role in many other neurocognitive processes and interacts with various other hormones and neurotransmitters to perform these functions. Here, we review the literature on how leptin influences brain development, neural degradation, Alzheimer's disease, psychiatric disorders, and more complicated cognitive functioning and feeding behaviors. We also discuss modulators of leptin and the leptin receptor as they relate to normal cognitive functioning and may mediate some of the actions of leptin in the brain. Although we are beginning to better understand the critical role leptin plays in normal cognitive functioning, there is much to be discovered.

The effects of lifestyle interventions on (long-term) weight management, cardiometabolic risk and depressive symptoms in people with psychotic disorders: a meta-analysis

AIMS

The aim of this study was to estimate the effects of lifestyle interventions on bodyweight and other cardiometabolic risk factors in people with psychotic disorders. Additionally, the long-term effects on body weight and the effects on depressive symptoms were examined.

MATERIAL AND METHODS

We searched four databases for randomized controlled trials (RCTs) that compared lifestyle interventions to control conditions in patients with psychotic disorders. Lifestyle interventions were aimed at weight loss or weight gain prevention, and the study outcomes included bodyweight or metabolic parameters.

RESULTS

The search resulted in 25 RCTs -only 4 were considered high quality- showing an overall effect of lifestyle interventions on bodyweight (effect size (ES)  =  -0.63, p<0.0001). Lifestyle interventions were effective in both weight loss (ES =  -0.52, p<0.0001) and weight-gain-prevention (ES =  -0.84, p = 0.0002). There were significant long-term effects, two to six months post-intervention, for both weight-gain-prevention interventions (ES =  -0.85, p = 0.0002) and weight loss studies (ES =  -0.46, p = 0.02). Up to ten studies reported on cardiometabolic risk factors and showed that lifestyle interventions led to significant improvements in waist circumference, triglycerides, fasting glucose and insulin. No significant effects were found for blood pressure and cholesterol levels. Four studies reported on depressive symptoms and showed a significant effect (ES =  -0.95, p = 0.05).

CONCLUSION

Lifestyle interventions are effective in treating and preventing obesity, and in reducing cardiometabolic risk factors. However, the quality of the studies leaves much to be desired.
