Psychosocial processes influencing weight management among persons newly prescribed atypical antipsychotic medications

Clinical, Biochemical and Genetic Variables Associated With Metabolic Syndrome in Patients With Schizophrenia Spectrum Disorders Using Second-Generation Antipsychotics: A Systematic Review

Background: Individuals with severe mental illness experience increased morbidity and mortality compared to the general population. Adverse effects of antipsychotics, including weight gain, may contribute to the development of metabolic syndrome (MetS), which is associated with increased risks of all-cause and cardiovascular disease mortality. We aim to provide a comprehensive overview of clinical, biochemical and genetic factors associated with MetS among patients with schizophrenia spectrum disorders using second-generation antipsychotics (SGA). Methods: A literature search was performed in Pubmed and Embase to identify all cohort studies, cross-sectional studies and clinical trials investigating associations with MetS in patients with schizophrenia spectrum disorders using SGAs. We extracted and enumerated clinical, biochemical and genetic factors reported to be associated with MetS. We defined factors associated with MetS as factors being reported as associated with MetS in two or more studies. Results: 58 studies were included in this review (n = 12,123). In total, 62 factors were found to be associated with increased risk of MetS. Thirty one out of 58 studies investigated factors that were reported as associated with MetS in two or more studies. With regard to clinical factors, we found gender, higher age, concomitant use of mood stabilizers, higher baseline and current BMI, earlier SGA exposure, higher dose, longer duration of treatment, psychosis and tobacco smoking to be significantly associated with MetS. Furthermore, the biochemical factors hypo-adiponectinemia, elevated levels of C-reactive protein (CRP) and higher white blood cell (WBC) count were identified as factors associated with MetS. Among pharmacogenetic factors, the rs1414334 C-allele of the HTR2C-gene was associated with MetS in patients using SGA. Conclusion: In this systematic review investigating clinical, biochemical and genetic factors associated with MetS in patients using SGAs we found that higher age, higher baseline BMI, higher current BMI and male as well as female gender were positively associated with MetS across all antipsychotics. This study may set the stage for the application of clinical, biochemical and genetic factors to predict the risk of developing MetS in patients using SGAs. Future research is needed to determine which patients using SGAs are at risk to develop MetS in clinical practice.

The experience of body image concerns in patients with persecutory delusions: 'People don't want to sit next to me'

OBJECTIVE

Persecutory delusions typically build on feelings of inter-personal vulnerability linked to negative views of the self. Negative body image is an overlooked aspect of this link between the self-concept and paranoia.

DESIGN

This study explores body image from the first-person perspective of patients with persecutory delusions.

METHOD

Semi-structured interviews, analysed using interpretative phenomenological analysis, were conducted with twelve patients with persecutory delusions in the context of psychotic disorders.

RESULTS

Four super-ordinate themes emerged. First, appearance as a source of threat accounted for how negative body image increased feelings of vulnerability and fed into the content of paranoia and voices (e.g., 'I feel that everybody is noticing that I'm getting bigger and bigger and laughing at me'). Second, there was the negative impact of uncontrollable and unwanted weight gain, especially following antipsychotic medication (e.g., 'I ballooned up to 23 stone'). Third, feeling stuck captured the hopelessness and resignation in relation to appearance (e.g., 'I've become so accustomed to being overweight that I've accepted it as my lot'). Finally, looking well symbolises feeling well represented the importance of appearance in determining mental well-being (e.g., 'If I've got clean clothes and I put makeup on, at least I feel that I'm looking after myself').

CONCLUSIONS

Patients with persecutory delusions described appearance-related concerns making them feel negative towards themselves, inferior to other people, and vulnerable to harm. Appearance-related distress was broader than weight gain, including dissatisfaction with skin, clothing, and attractiveness. Negative body image may be a contributory factor in the occurrence of paranoia.

PRACTITIONER POINTS

Body image concerns may be of particular relevance in patients with persecutory delusions due to weight gain, inactivity, and medication side effects. Body image concerns include weight gain and broader aspects of appearance. Negative body image contributes to feelings of vulnerability, potentially worsening paranoid fears. It may be helpful for practitioners to explore the psychological impact of weight gain and body image concerns in patients with psychosis.

The "Double Whammy": Women's Experiences of Weight Gain After Diagnosis and Treatment for Schizophrenia Spectrum Disorders

High levels of lifestyle risk factors compound medication side effects, resulting in high rates of obesity among people with schizophrenia spectrum disorders (SSDs). Obesity and related comorbidities increase the levels of disability and disadvantage in this population. Little research has explored the lived experiences in relation to this issue, and less has considered the experiences of women. Our aim in this study was to understand the experiences of women who gained weight after their diagnosis and treatment for SSDs. We carried out up to three in-depth qualitative interviews with 11 women over 2 years. Data were analyzed using constructivist grounded theory procedures. The women described a "double whammy"-like experience whereby weight gain and obesity came with their diagnosis and treatment of an SSD and brought with it additional challenges. The double whammy parallels the co-occurrence of mental illness and substance misuse. Implications of these parallels for service provision are discussed.

An Investigation of Cardiovascular Risks in a Group of Children and Adolescents Who Use Atypical Antipsychotics

This study was conducted to identify the metabolic parameters and body measurements associated with cardiovascular risks in a group of children and adolescents who as part of inpatient treatment received atypical antipsychotics at a psychiatric hospital in Turkey. Body mass indexes (BMIs), waist circumferences (WCs), diastolic blood pressures (DBPs), systolic blood pressures (SBPs) and heart rates (HRs) of the patients were evaluated during hospitalization and at discharge. A statistically significant difference was found among the mean BMIs, WCs, DBPs and HRs of the patients at the stages of their hospitalization and discharge (p < 0.05). On the basis of the study findings, it is recommended that mental health nurses evaluate these risk factors in children and adolescents and provide education on this subject to the patients and their families.

Physical health and well-being: Experiences and perspectives of young adult mental health consumers

Compromised physical health and raised levels of morbidity and mortality are experienced by young people (16-24 years) with mental illness, and are compounded by psychotropic medication. How this group conceives and experiences physical health is not well understood. We investigated the meanings, beliefs, and endeavours of young people that impact their physical health understandings and behaviours. The present study formed the qualitative phase of a sequential mixed-methods study, and incorporated semistructured interviews with 12 hospitalized young people. Qualitative content analysis was used to analyse data. Participants held a holistic ideal of physical health that they did not meet. Weight change, poor sleep, and limited exercise adversely impacted their lives and self-image. Sedentary behaviour, reduced energy, and limited health literacy compromised effective management of physical health. Young people needed structure and support to assist them in addressing their physical health needs when amotivation overwhelmed their internal resources. Nurses are well placed to help young people increase their competency for health management. Individualized information and methods to promote good physical health are required for this group in jeopardy from physical morbidity and mortality.

Gender differences in mood stabilizer medications prescribed to Veterans with serious mental illness

BACKGROUND

Mood stabilizer medications (MSMs) can induce significant weight gain and other metabolic side effects. Research suggests that women are more susceptible to psychotropic medication-induced metabolic side effects than men. We examined gender differences in the likelihood of receiving an MSM with a lower liability for weight gain using data from the U.S. Department of Veterans Affairs (VA) healthcare system.

METHODS

We identified 3823 VA patients with a schizophrenia or bipolar disorder diagnosis who initiated treatment with a MSM between 10/2006 and 9/2011. We used multivariable logistic regression analysis to examine gender differences in the likelihood of incident prescription of MSMs with low versus medium/high metabolic risk, adjusting for fiscal year of prescribing and demographic, mental health, and physical health characteristics.

RESULTS

Overall, 47% of women were prescribed a low metabolic risk MSM compared to 26% of men (p<0.0001). In multivariable analysis, women were 2.19 times as likely as men to be prescribed a low metabolic risk MSM (95% CI: 1.84-2.60, p<0.0001). Several demographic and clinical covariates were also independently related to prescribing of MSMs by level of metabolic risk.

LIMITATIONS

This study used retrospective administrative data collected from a VA healthcare system database, which does not allow us to understand the context in which MSM treatment decisions were made.

CONCLUSIONS

Prescribing choices for MSMs by VA mental health prescribers and female Veterans may reflect a growing awareness of the potential adverse health consequences of these treatments in women.

Gender differences in antipsychotics prescribed to veterans with serious mental illness

OBJECTIVE

To examine gender differences in prescribing of antipsychotic medications (APMs) according to their liability for weight gain and other metabolic side effects.

METHOD

We identified 4510 patients with schizophrenia or bipolar disorders receiving usual care in a Veterans Affairs (VA) health care network in the U.S. mid-Atlantic region who initiated treatment with an APM between October 2006 and September 2011. We used multivariable logistic regression to examine gender differences in the likelihood of incident prescription of APMs with low versus medium/high metabolic risk, adjusting for fiscal year of prescribing and selected Veteran demographic, mental health and physical health characteristics.

RESULTS

Overall, 58% of women were prescribed an APM with a low risk of metabolic side effects compared to 45% of men (P<.001). In multivariable analysis, women Veterans were 1.47 times as likely as men to be prescribed a low-metabolic-risk APM (95% confidence interval: 1.26-1.73, P<.001). Several demographic and clinical covariates were also independently related to prescribing of APMs by level of metabolic risk.

CONCLUSIONS

The results may suggest that prescribing choices for APMs by VA mental health prescribers and female Veterans reflect a growing awareness of the potential adverse health consequences of these treatments in women.

Physical Health Risk Behaviours in Young People with Mental Illness

Comorbid physical health conditions, commonly associated with mental illness, contribute to increased morbidity and reduced life expectancy. The trajectory to poorer health begins with the onset of mental illness. For young people with mental illness, health risk behaviours and poor physical health can progress to adulthood with long-term detrimental impacts. Using a cross-sectional survey design, self-reported health risk behaviours were gathered from 56 young (16-25 years) Australians who had been hospitalised for mental illness and taking psychotropic medication. Smoking, alcohol use, minimal physical activity, and lack of primary health care were evident. While these behaviours are typical of many young people, those with mental illness have substantially increased vulnerability to poor health and reduced life expectancy. Priority needs to be given to targeted health promotion strategies for young people with mental illness to modify their risky long-term health behaviours and improve morbidity and mortality outcomes. Nurses in mental health settings play a vital role in promoting young peoples' well-being and preventing poorer physical health outcomes. Implementation of a cardiometabolic health nurse role in inpatient settings for young people with mental illness could facilitate prevention and early intervention for health risk behaviours.

The experience of weight gain as a result of taking second-generation antipsychotic medications: the mental health consumer perspective

This interpretive qualitative study aimed to describe and construct the meaning of the experience of living with the weight gain associated with second-generation antipsychotics. A qualitative study that incorporated the tenets of phenomenology and utilized in-depth interviews was conducted with eight mental health consumers. Thematic analysis resulted in three themes: Grappling with the weight; Living with the consequences of being overweight; and Experiencing negative emotions about the weight gain. The findings indicate that consumers struggle to manage the insatiable appetite and the related weight gain associated with second-generation antipsychotic medication, as well as the numerous associated physical and emotional issues. Adherence with prescribed second-generation antipsychotic medication was also affected and a number of the participants indicated they had ceased or considered ceasing their medication because of the weight gain associated with the drugs.
