Variables associated with alcohol, drug, and daily smoking cessation in patients with severe mental illnesses

BACKGROUND: Co-occurrence of substance use disorders and severe mental illnesses (SMIs) is a major U.S. public health issue, although the role of tobacco is usually neglected. This study explored variables associated with alcohol, drug, and smoking cessation in a naturalistic setting. METHOD: Logistic regression was used to study variables associated with cessation of alcohol and drug use disorder and daily smoking in 560 SMI inpatients and outpatients from central Kentucky facilities. Patients with a lifetime history of alcohol or drug use disorder were considered to be in cessation if they had not suffered from abuse or dependence during the last year. Alcohol and drug use disorder diagnoses were determined using the Clinician Rating of Alcohol and Drug Use Disorder. Patients were recruited from July 2000 to March 2003. RESULTS: The cessation rates for alcohol and drug use disorders were, respectively, 44% (95% CI = 39% to 49%) and 46% (CI = 40% to 51%); these were higher than the daily cigarette smoking cessation rate of 10% (CI = 7% to 13%). Drug use disorders (p < or = .02), outpatient status (p < .001), and having a medical complication of obesity (diabetes mellitus, hypertension, or hyperlipidemia; p < .001) were significantly associated with alcohol cessation. Alcohol use disorder (p < .001), starting treatment with psychiatric medications after 33 years of age (p < .001), taking these medications for 14 years or more (p = .02), schizophrenia diagnosis (p < .001), outpatient status (p = .03), and obesity (p = .04) were significantly associated with drug cessation. Cessation of daily smoking was associated with hypertension (p = .02), late start of treatment with psychiatric medications (> 33 years old; p = .01), and lack of lifetime drug abuse (p < .001). CONCLUSIONS: These results are limited by the cross-sectional and naturalistic design but suggest that public health experts, researchers, and clinicians need to mindfully address smoking cessation in patients with SMIs. Clinicians may want to consider that medical illnesses may motivate patients with SMIs to stop substance abuse and that patients with SMIs who abuse both alcohol and drugs rarely stop abusing just one of them.     

Use of general medical services by VA patients with psychiatric disorders

OBJECTIVE: Patients with psychiatric disorders, particularly those with severe mental illnesses, have high rates of undetected and untreated medical problems and substantially elevated mortality rates due to medical illness. The authors sought to develop a better understanding of the demographic, medical, and psychiatric characteristics of this population to inform efforts to improve the medical care of these persons. METHODS: Using Department of Veterans Affairs (VA) databases, the authors examined use of medical services by 175,653 patients who were treated in Southern California and Nevada during fiscal year 2000. Multivariate regression models were used to examine factors affecting receipt of any medical care and the number of medical visits. RESULTS: Patients with psychiatric diagnoses had fewer medical visits than other VA patients; the largest differences were seen for patients with severe mental illnesses. Patients who were younger and male had few visits. Patients with diabetes or hypertension who had been diagnosed as having schizophrenia, bipolar disorder, or an anxiety disorder had substantially fewer visits than those who did not have these psychiatric diagnoses. Patients older than 50 years were less likely to have any medical care if they had a diagnosis of a substance use, depressive, bipolar, or anxiety disorder or posttraumatic stress disorder. CONCLUSIONS: Use of medical care varies by psychiatric diagnosis. Young adults with schizophrenia and posttraumatic stress disorder and adults of all ages with bipolar disorder have an especially high risk of not receiving general medical services. Interventions to improve medical care may need to be tailored to the population being targeted.     

Cardiovascular disease and diabetes in people with severe mental illness position statement from the European Psychiatric Association (EPA), supported by the European Association for the Study of Diabetes (EASD) and the European Society of Cardiology (ESC)

People with severe mental illnesses, such as schizophrenia, depression or bipolar disorder, have worse physical health and reduced life expectancy compared to the general population. The excess cardiovascular mortality associated with schizophrenia and bipolar disorder is attributed in part to an increased risk of the modifiable coronary heart disease risk factors; obesity, smoking, diabetes, hypertension and dyslipidaemia. Antipsychotic medication and possibly other psychotropic medication like antidepressants can induce weight gain or worsen other metabolic cardiovascular risk factors. Patients may have limited access to general healthcare with less opportunity for cardiovascular risk screening and prevention than would be expected in a non-psychiatric population. The European Psychiatric Association (EPA), supported by the European Association for the Study of Diabetes (EASD) and the European Society of Cardiology (ESC) published this statement with the aim of improving the care of patients suffering from severe mental illness. The intention is to initiate cooperation and shared care between the different healthcare professionals and to increase the awareness of psychiatrists and primary care physicians caring for patients with severe mental illness to screen and treat cardiovascular risk factors and diabetes.     

Correlates of overweight and obesity in 644 patients with bipolar disorder

OBJECTIVE: Overweight and obesity are common clinical problems encountered in the treatment of bipolar disorder. We therefore assessed the prevalence and clinical correlates of overweight, obesity, and extreme obesity in 644 bipolar patients. METHOD: 644 outpatients with DSM-IV bipolar disorder in the Stanley Foundation Bipolar Treatment Outcomes Network were evaluated with structured diagnostic interviews and clinician- and self-administered questionnaires to determine bipolar disorder diagnoses, demographic and historical illness characteristics, comorbid Axis I diagnoses, medical histories, health habits, and body mass indices (BMMs). RESULTS: Fifty-eight percent of the patients with bipolar disorder were overweight, 21% were obese, and 5% were extremely obese. American patients had significantly higher mean (p < .0001) BMIs and significantly higher rates of obesity (p < .001) and extreme obesity (p < .001) than European patients. Significant associations (p < or = .001) were found between overweight, obesity. and extreme obesity and gender, age, income level, comorbid binge-eating disorder, hypertension, arthritis, diabetes mellitus, exercise habits, and coffee consumption. Current BMI and weight were each correlated with the number of weight gain-associated psychotropics to which patients had been exposed. Multinomial logistic regression (adjusted for site and eating disorder diagnosis and corrected for multiple comparisons) showed that (1) overweight was significantly associated with male gender and hypertension (p < .001), (2) obesity was significantly associated with hypertension (p < .001), and (3) extreme obesity was significantly associated with hypertension and arthritis (p < .001). CONCLUSION: Overweight, obesity, and extreme obesity were common in this group of bipolar patients, although it was unclear that their prevalence rates were truly elevated, because overweight and obesity are increasingly common public health problems among the general population. Correlates of overweight and obesity in bipolar disorder include patient and treatment variables such as gender, geographical location, comorbid binge-eating disorder, age, income level, degree of exposure to weight gain-associated psychotropics, medical disorders associated with obesity, and health habits.     

Can body mass index help predict outcome in patients with bipolar disorder?

Objective:  Several studies have reported higher prevalence of obesity in patients suffering from bipolar disorder (BD). To study the relation of elevated body mass index (BMI) in patients with BD more closely, we investigated differences in sociodemographic, clinical, and medical characteristics with respect to BMI, with the hypothesis that BMI is related to prognosis and outcome.
Methods:  We measured the BMI of 276 subjects of a tertiary care sample from the Maritime Bipolar Registry. Subjects were 16 to 83 years old, with psychiatric diagnoses of bipolar I disorder (n = 186), bipolar II disorder (n = 85), and BD not otherwise specified (n = 5). The registry included basic demographic data and details of the clinical presentation. We first examined the variables showing a significant association with BMI; subsequently, we modeled the relationship between BMI and psychiatric outcome using structural equation analysis.
Results:  The prevalence of obesity in our sample was 39.1%. We found higher BMI in subjects with a chronic course (p < 0.001) and longer duration of illness (p = 0.02), lower scores on the Global Assessment of Functioning Scale (p = 0.02), and on disability (p = 0.002). Overweight patients had more frequent comorbid subthreshold social (p = 0.02) and generalized anxiety disorders (p = 0.05), diabetes mellitus type II (p < 0.001), and hypertension (p = 0.001). Subjects who achieved complete remission of symptoms on lithium showed significantly lower BMI (p = 0.01).
Conclusions:  Our findings suggest that BMI is associated with the prognosis and outcome of BD. Whether this association is causal remains to be determined.     

Treatment of co-morbid mental illness in primary care: how to minimize weight gain, diabetes, and metabolic syndrome

In patients with mental illness the increased risk from cardiovascular disease appears to be related to the increased incidence of obesity, hypertension, and diabetes mellitus. Barriers to the medical care in this patient population include diminished adherence to treatment and preventative recommendations, lack of willingness to engage in self-care activities, decreased access to affordable medical care, underestimation of risk by physicians, and adverse effects of commonly prescribed psychiatric medications. When managing patients with mental illness it is necessary to estimate the patient's metabolic and cardiovascular risk, monitor BMI, waist circumference, fasting glucose, and lipid profile regularly, evaluate psychiatric medications metabolic risk, and choose less "metabolically threatening" drugs. The promotion of healthy lifestyle choices among persons with serious mental illness is essential not only as part of their recovery, but as an integral part of preventing metabolic changes and weight gain linked to their illness and medication side effects. In patients with mental illness and co-morbid diabetes, metabolic syndrome, and obesity, psychiatrist and primary care clinicians should collaborate to establish a plan for healthy lifestyle habits (diet and activity regimen), encourage weight loss, and follow-up regularly using multispecialty teams to improve management.     

Patterns of psychiatric and physical comorbidities associated with panic disorder in a nationwide population‐based study in Taiwan

Chen Y‐H, Lin H‐C. Patterns of psychiatric and physical comorbidities associated with panic disorder in a nationwide population‐based study in Taiwan. Objective: This study aims to document a range of risk of psychiatric and physical comorbidities among PD patients using a nationwide population‐based dataset in Taiwan. Method: A total of 3672 patients with at least three consensus diagnoses with PD were included, together with 18 360 matched controls without PD. Logistic regression analyses were performed after adjusting for sociodemographic characteristics. Results: After adjusting for the patients’ sex, age and geographic region, patients with PD were more likely to have major depressive disorder (OR = 23.45), bipolar disorder (OR = 15.54), cardiac dysrhythmia (OR = 15.12), coronary heart disease (OR = 7.69), myocardial infarction (OR = 6.55), irritable bowel syndrome (OR = 4.82), peptic ulcers (OR = 4.30), cerebrovascular disease (OR = 3.61), hypertension (OR = 3.31), epilepsy (OR = 3.07), hepatitis (OR = 2.70), hyperlipidemia (OR = 2.20), asthma (OR = 2.17), schizophrenia (OR = 2.14), neoplasms (OR = 2.02), renal disease (OR = 1.89) and diabetes (OR = 1.26), compared to patients in the comparison cohort. Conclusion: We conclude that PD is associated with an array of psychiatric and physical illnesses.     

The Metabolic Syndrome in Patients With Severe Mental Illnesses

BACKGROUND: Since the introduction of the first atypical antipsychotics in the early 1990s, this class of medication has been increasingly relied upon for the treatment of a variety of patients with psychotic and mood disorders.DATA SOURCES: The following retrospective review was derived from the MEDLINE database using the search terms metabolic syndrome, insulin resistance, obesity, diabetes, severe mental illness, schizophrenia, bipolar disorder, mood disorders, depression, unipolar depression, and prevalence from 1966 to the present. LITERATURE SYNTHESIS: Coincident with the growing usage of these agents, there have been a growing number of literature reports of changes in metabolic homeostasis among patients taking these medications. These changes have led to interest in evaluating whether there is a relationship among these mental illnesses, their psychiatric treatments, and certain physical comorbidities known collectively as the metabolic syndrome. This article reviews the existing literature around the metabolic syndrome in patients with severe mental illnesses. CONCLUSION: Patients with severe mental illnesses, particularly schizophrenia and chronic mood disorders, demonstrate a higher prevalence of metabolic syndrome or its components compared with the general population. Based upon this increased risk in these patients, baseline and periodic medical evaluations should become a standard component in ongoing clinical assessment.     

Physical and psychiatric comorbidities among patients with severe mental illness as seen in Uganda

While psychiatric and physical comorbidities in severe mental illness (SMI) have been associated with increased mortality and poor clinical outcomes, problem has received little attention in low- and middle-income countries (LMICs). This study established the prevalence of psychiatric (schizophrenia, bipolar affective disorder, and recurrent major depressive disorder) and physical (HIV/AIDS, syphilis, hypertension and obesity) comorbidities and associated factors among 1201 out-patients with SMI (schizophrenia, depression and bipolar affective disorder) attending care at two hospitals in Uganda. Participants completed an assessment battery including structured, standardised and locally translated instruments. SMIs were established using the MINI International Neuropsychiatric Interview version 7.2. We used logistic regression to determine the association between physical and psychiatric comorbidities and potential risk factors. Bipolar affective disorder was the most prevalent (66.4%) psychiatric diagnoses followed by schizophrenia (26.6%) and recurrent major depressive disorder (7.0%). Prevalence of psychiatric comorbidity was 9.1%, while physical disorder comorbidity was 42.6%. Specific comorbid physical disorders were hypertension (27.1%), obesity (13.8%), HIV/AIDS (8.2%) and syphilis (4.8%). Potentially modifiable factors independently significantly associated with psychiatric and physical comorbidities were: use of alcohol for both syphilis and hypertension comorbidities; and use of a mood stabilisers and khat in comorbidity with obesity. Only psychiatric comorbidity was positively associated with the negative outcomes of suicidality and risky sexual behaviour. The healthcare models for psychiatric care in LMICs such as Uganda should be optimised to address the high burden of psychiatric and physical comorbidities.

     

Posttraumatic stress disorder in male military veterans with comorbid overweight and obesity: psychotropic, antihypertensive, and metabolic medications

Posttraumatic stress disorder (PTSD) is an important syndrome among military veterans. Little has been written about comorbid medical conditions of PTSD, particularly overweight and obesity. We focus on psychotropic and non-psychotropic drugs, their interactions, and metabolic issues most relevant to primary care physicians.Method: Data from the recently constituted PTSD program at the Department of Veterans Affairs Medical Center in Richmond, Va., were retrospectively reviewed to assess the prevalence and severity of comorbid overweight and obesity in male veterans with PTSD. Also, our database allowed us to correlate various drugs used to treat hypertension, diabetes mellitus, and dyslipidemia with body mass index (BMI).Results: The mean BMI of 157 veterans with PTSD (DSM-IV criteria) in this sample was in the obese range (30.3 ± 5.6 kg/m2). The number of drugs a given patient was taking for treatment of hypertension, diabetes mellitus, and dyslipidemia correlated with BMI. Psychotropic drugs associated with weight gain did not explain our findings.Conclusions: Overweight and obesity among our male veterans with PTSD strikingly exceeded national findings. The administration of psychotropic drugs associated with weight gain did not explain these findings. The number of medications used to treat hypertension, diabetes mellitus, and dyslipidemia correlated significantly with BMI. Rather than these medications explaining the high prevalence of overweight and obesity in our study population, obesity probably worsened these components of the metabolic syndrome, necessitating more aggressive treatment reflected in the high number of drugs prescribed.     

Obesity and medical illnesses in psychiatric patients admitted to a long-term psychiatric facility

Obesity and associated medical conditions may have an impact on morbidity and even mortality in patients with psychiatric disorders. The authors present the results of a survey of the prevalence of obesity and selected medical conditions among 420 consecutively admitted psychiatric inpatients at a long-stay facility and compare these data with those reported in the literature. Female psychiatric subjects had considerably higher rates of being either overweight or obese (69%) as compared to women in the general U.S. population (51%). Male psychiatric subjects did not differ significantly from their counterparts in the general population in being overweight or obese (nearly 55%). The majority of psychiatric subjects with essential hypertension, diabetes mellitus, dyslipidemias, cardiovascular disease, or sleep apnea were either overweight or obese (72%-87%). In this cross-sectional study, no associations could be deduced between psychotropic drug classes and specific medical conditions. No specific psychiatric diagnostic category was associated with a significantly greater prevalence of any specific medical condition, except that subjects with schizoaffective disorder appeared to have a higher prevalence of type II diabetes mellitus (11.6%). Subjects with predominant substance or alcohol abuse or dependence disorders had a lower prevalence of obesity and associated medical conditions.Obesity-either independently or additively along with a sedentary lifestyle, unhealthy dietary habits, and nicotine dependence-may have a serious impact on coexisting medical comorbidity in psychiatric patients. Judicious monitoring for obesity and rapid pharmacological and nonpharmacological intervention, where appropriate, by concerned clinicians may improve several coexisting medical conditions in psychiatric patients and thereby improve patients' overall quality of life.     

A comparison of adherence to hypoglycemic medications between Type 2 diabetes patients with and without serious mental illness

Inadequate self-management of chronic medical conditions like Type 2 diabetes may play a role in the poor health status of individuals with serious mental illnesses. We compared adherence to hypoglycemic medications and blood glucose control between 44 diabetes patients with a serious mental illness and 30 patients without a psychiatric illness. The two groups did not differ in their ability to manage a complex medication regimen as assessed by a performance-based measure of medication management capacity. However, significantly fewer patients with a mental illness self-reported nonadherence to their hypoglycemic regimens compared to those without a mental illness. Although individuals with mental illnesses also had better control of blood glucose, this metabolic parameter was not correlated with adherence to hypoglycemic medications in either patient group. The experience of managing a chronic mental illness may confer advantages to individuals with serious mental illnesses in the self-care of co-occurring medical conditions like Type 2 diabetes.     

High prevalence rates of diabetes and hypertension among refugee psychiatric patients

There is increasing evidence that immigrants and traumatized individuals have elevated prevalence of medical disease. This study focuses on 459 Vietnamese, Cambodian, Somali, and Bosnian refugee psychiatric patients to determine the prevalence of hypertension and diabetes. The prevalence of hypertension was 42% and of diabetes was 15.5%. This was significantly higher than the US norms, especially in the groups younger than 65. Diabetes and hypertension were higher in the high-trauma versus low-trauma groups. However, in the subsample with body mass index (BMI) measurements subjected to logistic regression, only BMI was related to diabetes, and BMI and age were related to hypertension. Immigrant status, presence of psychiatric disorder, history of psychological trauma, and obesity probably all contributed to the high prevalence rate. With 2.5 million refugees in the country, there is a strong public health concern for cardiovascular disease in this group.     

Obesity among individuals with serious mental illness

OBJECTIVE: To study the distribution and correlates of body mass index (BMI) among individuals with serious mental illness. METHOD: A total of 169 participants were recruited from randomly selected out-patients receiving community-based psychiatric care and were interviewed with items from the National Health and Nutrition Examination Survey (NHANES) III. Their BMI was compared with that of 2404 matched individuals from the NHANES data set. RESULTS: The distribution of BMI in the psychiatric sample significantly differed from that of the comparison group; 50% of women and 41% of men were obese compared with 27% and 20% in the comparison group. Within the psychiatric sample, higher BMI was associated with current hypertension and diabetes, a wish to weigh less, and reduced health-related functioning. CONCLUSION: Obesity is more prevalent among individuals with serious mental illness than in demographically matched individuals from the US general population. Among persons with mental illness, obesity is associated with co-occurring health problems.     

Education in mental health promotion and its impact on the participants' attitudes and perceived mental health

Awareness of the importance of maintaining physical health for patients with severe mental illnesses has recently been on the increase. Although there are several elements contributing to poor physical health among these patients as compared with the general population, risk factors for cardiovascular disease such as smoking, diabetes mellitus, hypertension, dyslipidemia, metabolic syndrome, and obesity are of particular significance due to their relationship with mortality and morbidity. These patients present higher vulnerability to cardiovascular risk factors based on several issues, such as genetic predisposition to certain pathologies, poor eating habits and sedentary lifestyles, high proportions of smokers and drug abusers, less access to regular health care services, and potential adverse events during pharmacological treatment. Nevertheless, there is ample scientific evidence supporting the benefits of lifestyle interventions based on diet and exercise designed to minimize and reduce the negative impact of these risk factors on the physical health of patients with severe mental illnesses.     

Phenomenologic subtypes in dementia and previous psychiatric hospitalization

Psychiatric features in dementia may reflect the coexistence of a previous ?functional”? mental disorder and dementia. To test this hypothesis we used the national Psychiatric Case Register (PCR) as a data source and (a) compared PCR data between phenomenologic subtypes of dementia patients with and without history of psychiatric hospitalization; (b) investigated in what way past psychiatric diagnoses relate to present dementia phenomenology. A small but significant portion of senile (31%) and arteriosclerotic (23%) dementia sufferers did have a documented history of psychiatric hospitalization. No significant or consistent differences concerning PCR demographic, clinical and clinical-administrative variables studied were found when dementia patients of each subtype, with and without previous psychiatric hospitalizations, were compared. However, phenomenologic subtypes with delusions and depression in senile and arteriosclerotic patients were significantly associated with previous psychiatric ?functional”? diagnoses of a similar phenomenology. We suggest that, at least in a subgroup of senile and arteriosclerotic dementia patients, the psychiatric subtypes of delusions and depression might reflect the coexistence of two separate mental illnesses.     

Use of the Diagnostic Interview Schedule in patients with diabetes mellitus

In routine clinical practice and in research interviews like the Diagnostic Interview Schedule (DIS), symptoms attributed to physical illness are excluded from contributing positively toward psychiatric diagnoses. The maximal rate of underdiagnosis which results from this diagnostic rule was determined in 114 patients with diabetes mellitus. When symptoms attributed to diabetes (total = 296, mean = 2.6 per patient) were discounted, 256 diagnoses were made. Eighteen additional diagnoses (a 6.7% increase) were appreciated when these excluded symptoms were considered as psychiatrically significant; however, only two of these new diagnoses were given to patients previously without a psychiatric diagnosis. The authors concluded that the DIS is sensitive in its detection of psychiatric illness in diabetes and perhaps other physical illnesses as well.     

Psychiatric disorders presenting in the elderly with type 2 diabetes mellitus

Diabetes mellitus (DM) is one of the major health problems of the elderly. Developed countries face an epidemic of Type 2 DM. Healthcare providers should be aware of the frequent coexistence of psychiatric conditions in elderly patients with DM. Dementia, depression, and anxiety are commonly seen in addition to other psychiatric conditions. The relationship between diabetes and psychiatric disorders is complex. Evidence suggests that common mechanisms may play a role in both the pathogenesis of DM and several psychiatric illnesses. Possible mechanisms, diagnosis, and management options are reviewed and discussed. Common mechanisms of psychiatric illness involving brain-derived neurotrophic factor, insulin resistance, and inflammatory cytokines are throwing new light that these psychiatric illnesses could be due to the complications of Type 2 DM. Periodic screening should be done in DM patients to identify the psychiatric complications. Healthcare professionals should routinely screen for psychiatric complications of DM in addition to the microvascular and macrovascular complications of DM. It is important to screen all diabetic elderly patients for mental health issues as these may interfere with self-care and the overall management of DM. Recognition and management of psychiatric disorders will help to optimize the diabetes management. Good diabetes control can also reduce the mental health complications in these patients.
