The prevalence of anxiety in respiratory and sleep diseases: A systematic review and meta-analysis. Respir Med 2024; 230:107677. [PMID: 38823565 DOI: 10.1016/j.rmed.2024.107677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Revised: 05/07/2024] [Accepted: 05/22/2024] [Indexed: 06/03/2024]
Abstract
BACKGROUND Anxiety is common in those with chronic physical health conditions and can have significant impacts on both quality of life and physical health outcomes. Despite this, there are limited studies comprehensively investigating the prevalence of anxiety in respiratory and sleep medicine settings. This systematic review and meta-analysis aims to provide insight into the global prevalence of anxiety symptoms/disorders in respiratory and sleep medicine outpatients. METHODS PubMed, Embase, Cochrane, PsycINFO and Google Scholar databases were searched from database inception to January 23, 2023 for studies assessing the prevalence of anxiety in adult (≥16 years) respiratory and sleep medicine outpatients. Data was screened and extracted independently by two investigators. Anxiety was measured using various self-report questionnaires, structured interviews, and/or patient records. Using CMA software for the meta-analysis, a random-effects model was used for pooled estimates, and subgroup analysis was conducted on relevant models using a mixed-effects model. RESULTS 116 studies were included, featuring 36,340 participants across 40 countries. The pooled prevalence of anxiety was 30.3 % (95%CI 27.9-32.9 %, 10,679/36,340). Subgroup analysis found a significant difference across type of condition, with pulmonary tuberculosis the highest at 43.1 % and COVID-19 outpatients the lowest at 23.4 %. No significant difference was found across anxiety types, country or age. Female sex and the use of self-report measures was associated with significantly higher anxiety estimates. CONCLUSIONS Anxiety is a common experience amongst patients in respiratory and sleep medicine outpatient settings. Thus, it is crucial that anxiety identification and management is considered by physicians in the field. REGISTRATION The protocol is registered in PROSPERO (CRD42021282416).

Abstract
BACKGROUND Delirium incidences during hospitalization are an important problem in elderly patients. The problem of delirium episodes in patients with obstructive disease during hospitalization was investigated. MATERIAL AND METHODS From a total of 37,156 subjects, the following were randomly selected: 32,261 patients with asthma, 4896 with chronic obstructive pulmonary disease (COPD), and 5455 without obstructive disease. Their ages ranged from 65-95 years, and they were hospitalized between 2006 and 2015. Delirium incidences were monitored based on the International Classification of Disease (ICD)-10 codes and medical documentation. RESULTS The delirium episodes during all hospitalizations were independently associated with asthma (odds ratio [OR] = 2.91, confidence interval [CI] = 1.62-5.84), with severe type of asthma (OR = 4.24, CI = 1.94-8.93), partim controlled asthma (OR = 3.1, CI = 1.29-8.46), and uncontrolled asthma (OR = 4.88, CI = 2.12-9.42). It was comparable with COPD as follows: all incidences of delirium during hospitalization (OR = 3.17, CI = 1.42-7.23) or severe COPD (III degree OR = 5.15, CI = 2.01-13.69). Elderly patients with asthma with uncontrolled or partially controlled asthma with a coincidence of advanced age, dementia, or smoking had a greater predisposition to delirium episodes, particularly after surgery. Additionally, delirium incidence caused death more frequently in patients with asthma than in those with COPD. CONCLUSION Elderly patients with asthma have a higher risk of delirium episodes during any hospitalization, and, frequently, it ends in death.

Abstract
BACKGROUND Although they are declining worldwide, neurotropic parasitic diseases are still common in developing and emerging countries. The aim of this study was to estimate the pooled prevalence and pooled association measures of comorbidities between mental disorders (anxiety, depression, bipolar disorder, and schizophrenia) and neurotropic parasitic diseases (malaria, cysticercosis, toxoplasmosis, human African trypanosomiasis, Chagas disease, and human toxocariasis) in developing and emerging countries. METHODS As the first meta-analysis on this topic, this study was performed in accordance with PRISMA guidelines. The protocol was registered in PROSPERO (N°CRD42017056521). The Medline, Embase, Lilacs, and Institute of Epidemiology and Tropical Neurology databases were used to search for articles without any restriction in language or date. We evaluated the quality of studies independently by two investigators using the Downs and Black assessment grid and pooled estimates using the random-effects method from CMA (Comprehensive Meta Analysis) Version 3.0. RESULTS In total, 18 studies published between 1997 and 2016 met our inclusion criteria. We found that the prevalence of anxiety and depression in people suffering from Chagas disease and/or neurocysticercosis was 44.9% (95% CI, 34.4-55.9). In 16 pooled studies that included 1782 people with mental disorders and 1776 controls, toxoplasmosis and/or toxocariasis were associated with increased risk of schizophrenia and/or bipolar disorders (odds ratio = 2.3; 95% CI, 1.7-3.2). Finally, toxocariasis and/or toxoplasmosis were associated with an increased risk of the onset of schizophrenia (odds ratio = 2.4; 95% CI, 1.7-3.4). CONCLUSION Our pooled estimates show that the associations between diseases studied are relatively high in developing and emerging countries. This meta-analysis supports the hypothesis that toxoplasmosis could be the cause of schizophrenia. These findings could prove useful to researchers who want to further explore and understand the associations studied.

Abstract
Introduction: Psychiatric morbidity has an increased prevalence in chronic obstructive pulmonary disease (COPD). Patients overall psychosocial status plays an important role in the development of depression which, when major, is said to occur in 19%–42% of cases of COPD. We aimed to study patterns of psychosocial issues in patients with COPD. Materials and Methods: This study was conducted over a period of 6 months in an Outpatient Department of Government Chest Disease Hospital Srinagar. A total of 100 COPD patients and 100 sex- and age-matched controls were included in this study and compared. The diagnosis of COPD was assessed by spirometry. Patterns of psychiatric morbidities were assessed using the Mini-International Neuropsychiatric Interview. Results: The frequency of psychiatric comorbidities was significantly higher (P < 0.001) in COPD patients (47%) as compared to controls (12%). The highest frequency of psychiatric morbidities in COPD patients was major depressive episode in 28% in comparison to 9% of controls. Other morbidities include panic disorder, dysthymia, generalized anxiety disorder, and suicidality. Conclusion: The frequency of psychiatric morbidities is increased in COPD patients as compared to controls. We recommend that all patients with COPD should be screened for psychiatric morbidity as there is enough scope for psychiatric services to be made available to these patients.

Abstract
Background As the data on the association of mental disorders and chronic physical diseases in developing and emerging countries is heterogeneous, this study aims to produce the first meta-analysis of these comorbidities. Methodology The meta-analysis protocol was registered in PROSPERO (N°CRD42017056521) and was performed in accordance with PRISMA guidelines. Initially, an article search was conducted on Medline, Embase, Lilacs and the Institut d’Epidémiologie et de Neurologie Tropicale database [Institute of Epidemiology and Tropical Neurology], as well as manually, with no restriction on language or date focusing on mental disorders, chronic diseases and neurotropic diseases. Two independent investigators assessed the quality of the studies which met the inclusion criteria using the Downs and Black assessment grid. The pooled estimates were calculated out using a random-effects method with CMA software Version 3.0. A meta-regression was then performed, and the significance level was set at 0.05. Results Of the 2604 articles identified, 40 articles involving 21,747 subjects met the inclusion criteria for co-morbidities between mental disorders and chronic physical diseases. Thirty-one articles were included in the meta-analysis of prevalence studies and 9 articles in that of the analytical studies. The pooled prevalence of mental disorders in patients with chronic physical diseases was 36.6% (95% CI, 31.4–42.1) and the pooled odds ratio was 3.1 (95% CI, 1.7–5.2). There was heterogeneity in all the estimates and in some cases, this was explained by the quality of the studies. Conclusion Some estimates regarding the prevalence of mental disorders in people with chronic physical diseases living in developing and emerging countries were similar to those in developed countries. Mental disorders are a burden in these countries. In order to respond effectively and efficiently to the morbidity and mortality associated with them, mental health care could be integrated with physical care.

Abstract
In the UK, chronic respiratory diseases cause 13% of adult disability. The major chronic respiratory disease is chronic obstructive pulmonary disease (COPD), a condition involving chronic airway inflammation that causes airflow obstruction and destruction of lung tissue. This leads to a progressive loss of respiratory membrane, which accounts for the clinical manifestation of COPD, which is difficulty maintaining sufficient gas exchange to meet metabolic demands. The primary cause is smoking, with the vast majority of COPD patients having a past or present history of smoking. However, exposure to industrial pollutants is also a contributing factor, as is a rare genetic predisposition to developing COPD.

Abstract
The present paper is a narrative review focusing on the psychological impact, identification of protective factors, and interventions minimizing the psychological burdens of chronic obstructive pulmonary disease (COPD). The research reviews studies on neurocognitive functions, personality, emotional problems, and health-related quality of life. This is done with regard to resources as well as activities enabling or enhancing a patient's adaptation. PubMed and PsychArticles databases were searched for relevant medical (eg, CODP, emphysema), psychopathology (eg, depression), and psychological (eg, personality) keywords, followed by hand search. After application of the inclusion and exclusion criteria, the search resulted in 82 articles and book chapters. The choice was based on evidence accepted by evidence-based medicine, although at different levels of strength. Psychological experiencing of COPD appears to be very unequally represented with scientific research on emotional problems and functioning decrease significantly outnumbering those addressing resources or effective interventions. As our initial literature search called for an urgent need for further exploration, we have carefully pointed out numerous areas where the knowledge on how to protect or restore psychological well-being among COPD patients should be broadened.

Abstract
A considerable amount of literature has described the prevalence of anxiety in patients with the lung condition chronic obstructive pulmonary disease (COPD). Few, if any, papers have reviewed the inter-relationship between anxiety symptoms and self-management interventions in this population. This is the aim of the current review. First, the review examines the evidence suggesting that anxiety is more common in COPD than other populations. Secondly, the focus shifts to evaluating the evidence for and against the efficacy of COPD self-management programmes. Finally this paper examines the relationship between anxiety and COPD self-management with particular reference to the benefits and possible harm of some COPD self-management goals and anxious patients.

Abstract
OBJECTIVE Few studies have investigated the relationship between chronic obstructive pulmonary disease (COPD) and anxiety disorder outcomes. We sought to investigate the association in a large national sample. METHODS Cases were identified from Taiwan's National Health Insurance Research Database who were aged 15 years and above, with a new primary diagnosis of COPD (International Classification of Diseases, Ninth Revision codes: 491, 492, 494 and 496) between 2000 and 2007. The 29,951 cases identified were compared to 29,951 controls matched on sex, age, urban/rural residence and socioeconomic status based on insurance premium. Both groups were followed until the end of 2008 for instances of anxiety disorders. Competing risk-adjusted Cox regression analyses were applied, adjusting for matching variables, Charlson comorbidity index, hospital admission days and daily dose of prednisone. RESULTS Of the 59,902 subjects, 3951 were found to have anxiety disorders during a mean (SD) follow-up period of 5.5 (2.5) years. COPD, female, urban residence, lower dose of prednisone use, depressive disorders and higher outpatient visits were independent predictors of incident anxiety disorder. CONCLUSIONS COPD was associated with increased risk of an anxiety disorder diagnosis, independent of a number of potential confounding factors.

Abstract
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease characterized by progressive and only partially reversible symptoms. Worldwide, the incidence of COPD presents a disturbing continuous increase. Anxiety and depression are remarkably common in COPD patients, but the evidence about optimal approaches for managing psychological comorbidities in COPD remains unclear and largely speculative. Pharmacological treatment based on selective serotonin reuptake inhibitors has almost replaced tricyclic antidepressants. The main psychological intervention is cognitive behavioral therapy. Of particular interest are pulmonary rehabilitation programs, which can reduce anxiety and depressive symptoms in these patients. Although the literature on treating anxiety and depression in patients with COPD is limited, we believe that it points to the implementation of personalized strategies to address their psychopathological comorbidities.

Abstract
Chronic obstructive pulmonary disease (COPD) is a progressive and debilitating respiratory condition that leads to significant burden, both medically and financially. It affects millions of people worldwide and causes significant morbidity and mortality. Most detailed information related to its prevalence, morbidity, and mortality comes from high-income countries, but 90% of COPD-related deaths occur in low- and middle-income countries. Cigarette smoking is the main risk factor for developing COPD, but other risk factors do exist and need to be recognized. A majority of morbidity and mortality as well as health care costs occur from acute exacerbations of COPD with a known phenotype of patients being "frequent exacerbators." Health care costs for COPD are not only from treatment of exacerbations, such as hospitalization, but also medication costs for maintenance therapy and outpatient treatment. COPD has been linked with many comorbidities leading to significant burden of disease. The goal of this review is to evaluate the overall burden of disease including prevalence, morbidity, mortality, health care costs, and economic costs.

[PMID: 25466692 DOI: 10.1016/j.jns.2014.10.034] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2014] [Revised: 09/30/2014] [Accepted: 10/27/2014] [Indexed: 10/24/2022]
Abstract
BACKGROUND In high-income countries with ageing populations, delirium is most prevalent in older adults and in palliative and intensive care settings. The prevalence and aetiology of delirium are likely to differ in low income countries, including sub-Saharan Africa (SSA), due to different population demographics, disease burden and exposure to pathogens. We reviewed published literature relating to the prevalence, clinical features and underlying causes of delirium in SSA and compare this with that published in high-income countries in order to identify knowledge and clinical service gaps, and priorities for further research. METHODS We performed a narrative review by comprehensively searching the following databases: Medline, PsychInfo, Embase and PubMed. Studies published between January 1 1975 and December 31 2013 in all languages, including the terms 'delirium', 'acute brain syndrome', 'organic brain syndrome', or 'acute confusion' originating from SSA were included. In addition, reference lists of included articles and online databases of African medical literature were hand-searched. We also included case series and case reports due to paucity of published studies. RESULTS We identified a total of 46 relevant studies. Delirium was the main focus of only one cross-sectional study, whereas most included delirium in studies on neuropsychiatric conditions. Only two studies reported prevalence in older adults. Most studies reported very low (<2%) delirium prevalence, whereas delirium in psychiatric inpatient and outpatient settings was higher than expected (18.2%-29.9%). Descriptive studies of 'bouffee delirante' from psychiatry settings were often describing delirium. Infection and HIV seropositivity were common associations of delirium throughout these studies. There were no studies of intensive, critical or surgical care settings or of management strategies. CONCLUSIONS We currently know very little about the prevalence, presentation and aetiology of delirium in developing countries. This knowledge gap should be tackled with some urgency, in order to address questions of screening, diagnosis, prevention and management in this setting.

Abstract
Background. Biomass smoke exposure is a known risk factor for chronic bronchitis. Psychiatric comorbidities may have significant impact on the quality of life of patients with chronic bronchitis. Methods. Women who engage in fish preservation by drying over burning firewood in a fishing community were recruited for this survey. The British medical research questionnaire was used to determine chronic bronchitis, and psychological distress was determined using the hospital anxiety and depression scale. Results. A total of 342 women were recruited for this study and 63 of them had chronic bronchitis. 96 women had features suggestive of psychological distress: 57 (16.6%) women with anxiety, 51 (14.9%) women with depression and 12 women (3.5%) had combined features. Psychological distress was more common among women with chronic bronchitis. Anxiety was significantly associated with chronic bronchitis and the level of biomass exposure while depression was significantly associated with chronic bronchitis, level of exposure, and a history of sleeping in the fish smoking room. Conclusion. Anxiety and depression show significant association with chronic bronchitis among women with biomass smoke exposure with the level of exposure having an aggravating effect on the relationship.

Abstract
BACKGROUND Chronic Obstructive Pulmonary Disease (COPD) is a multi-systemic and progressive disease. However the determinants of its impact on health related quality of life are not well-studied or understood in Nigeria. OBJECTIVES To assess the determinants of health related quality of life in COPD. METHODS Patients with stable COPD were recruited consecutively from the outpatient clinics of a university hospital. Health Related Quality of Life (HRQL) was assessed using the St. George's Respiratory Questionnaire (SGRQ) and the Forced Expiratory Volume in one second (FEV1), Forced Vital Capacity (FVC) were measured by a vitalograph spirometer. RESULTS Fifty patients were recruited for this study (male = 60%). The mean (SD) age was 69 (9) years. The overall mean (SD) SGRQ scores was 45.9 (26.5), 50.6 (29.2), 29.7 (19.9), 38.8 (22.0) for the symptom, activity, impact and total scores respectively. After adjusting for age, sex and smoking, self-reported breathlessness independently predicted on average 25.2, 36.8, 13.65 and 22.9 points increase in SGRQ symptom, activity, impact and total scores respectively. Self-reported weight loss predicted 12.2 points increase in the impact subscale. CONCLUSIONS Self-reported breathlessness and weight loss are independent predictors of low HRQL score in COPD.

Abstract
OBJECTIVE This study sought to elicit and describe the first-hand experiences of anxiety in community patients with stable chronic obstructive pulmonary disease (COPD). Anxiety is common among patients with COPD. Clinical anxiety affects up to two thirds of patients, leading to reduced quality of life and physical functioning. There has been little research exploring the experiences of anxiety in patients with COPD, particularly in individuals with stable respiratory symptoms. METHODS We interviewed 14 community patients with stable COPD and self-reported symptoms of anxiety. Data were analyzed using thematic network analysis to develop basic, organizing, and global themes. RESULTS Patients reported intense thoughts of fear, hopelessness, and confusion that were associated with the anxiety and panic attacks. Self-management was important, particularly self-talk coping strategies. CONCLUSIONS Unmanaged anxiety seems to be particularly distressing for patients with COPD. Self-management strategies can be highly effective in preventing and managing anxiety.

Abstract
OBJECTIVE Patients with chronic obstructive pulmonary disease (COPD) and comorbid mental disorders are known to have worse health status. The association between these variables remains complex and poorly understood. We sought to better understand the association between COPD severity, mental disorders (depression/anxiety), and health status. METHOD This cross-sectional study compared participants without COPD or with mild COPD (n = 162) to those with moderate (n = 25), severe (n = 38), and very severe (n = 26) COPD. We recruited participants from a primary care and a pulmonary clinic at a veterans affairs medical center between July 2001 until September 2002. We used the Patient Health Questionnaire to screen for depression and anxiety and the Posttraumatic Stress Disorder Checklist to screen for posttraumatic stress disorder. Health status was assessed with the veteran's version of the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) and the Shortness of Breath Questionnaire (SOBQ). RESULTS COPD severity was associated with worse physical status and dyspnea as measured by the SF-36 physical component summary and the SOBQ but was not associated with worse mental status as measured by the SF-36 mental component summary. At each level of COPD severity, participants with mental disorders had worse health status and dyspnea as measured by the SF-36 physical component summary, mental component summary, and SOBQ. Significant linear trends with COPD severity were associated with increased prevalence of any depressive disorder, major depressive disorder, and nonpanic/non-PTSD anxiety disorders (all tests for linear trend, P < .01). CONCLUSIONS Independent of COPD severity, comorbid mental disorders were associated with worse health status and dyspnea. Studies are needed to determine whether patients with comorbid mental disorders may have more significant improvement in physical symptoms and functioning if providers focus more on psychiatric conditions.

Abstract
OBJECTIVE This meta-analysis was aimed to evaluate the differences in aggregated prevalence of depressive symptoms among people with chronic obstructive pulmonary disease (COPD) as compared to controls without COPD and to determine underlying moderators to explain potential heterogeneity of prevalence. METHODS A meta-analysis of published work was performed using the random effect model. A total of eight studies were identified. We calculated the differences in prevalence proportion of depressive symptoms in patients with COPD versus controls. Meta-regression and subgroup analysis were performed to identify factors that may contribute to heterogeneity. RESULTS The prevalence proportion of depressive symptoms was found to be significantly higher (pooled odds ratio: 2.81; 95% CI: 1.69-4.66) among 39587 individuals with COPD as compared to 39,431 controls (24.6%, 95% CI: 20.0-28.6% vs. 11.7%, 95% CI: 9-15.1%). Meta-regression was conducted to account for the heterogeneity of the prevalence proportion, but moderators like mean age, gender, mean FEV(1) and proportion of current smokers among COPD patients were nonsignificant and could not explain heterogeneity in prevalence of depressive symptoms. Subgroup analyses showed no significant differences based on different methods of assessment of depressive symptoms and countries sampled. CONCLUSION This meta-analytical review identified higher prevalence of depressive symptoms among COPD patients, and meta-regression showed that demographic and clinical factors were not the determinants of heterogeneity in prevalence of depressive symptoms.

Abstract
OBJECTIVE To review evidence regarding the prevalence, causation, clinical implications, aspects of healthcare utilisation and management of depression and anxiety in chronic heart failure and chronic obstructive pulmonary disease. DESIGN A critical review of the literature (1994-2009). FINDINGS The prevalence of depression and anxiety is high in both chronic obstructive pulmonary disease (8-80% depression; 6-74% anxiety) and chronic heart failure (10-60% depression; 11-45% anxiety). However, methodological weaknesses and the use of a wide range of diagnostic tools make it difficult to reach a consensus on rates of prevalence. Co-morbid depression and anxiety are associated with increased mortality and healthcare utilisation and impact upon functional disability and quality of life. Despite these negative consequences, the identification and management of co-morbid depression and anxiety in these two diseases is inadequate. There is some evidence for the positive role of pulmonary/cardiac rehabilitation and psychotherapy in the management of co-morbid depression and anxiety, however, this is insufficient to guide recommendations. CONCLUSIONS The high prevalence and associated increase in morbidity and mortality justifies future research regarding the management of anxiety and depression in both chronic heart failure and chronic obstructive pulmonary disease. Current evidence suggests that multi-faceted interventions such as pulmonary and cardiac rehabilitation may offer the best hope for improving outcomes for depression and anxiety.

Abstract
Although problems in mental health constitute 14% of the global burden of disease, mental health has been largely missing from the international health agenda. The burden from mental illness is largely attributable to the chronically disabling nature of depression and other common mental disorders, alcohol-use and substance-use disorders, and psychoses. The last decade has seen some progress in addressing this gap. In 2001, the World Health Report, Mental Health: New Understanding, New Hope, drew attention to the situation, with an appeal from the World Health Organization's Director General that 'mental health - neglected for far too long - is crucial to the overall well-being of individuals, societies and countries and must be universally regarded in a new light.' In September 2007, the journal Lancet launched the global mental health series, which highlighted the public-health dimension of mental health, identified barriers to receiving treatment, and gave a call for action to the nations of the world, to make a major commitment to upgrade the quality of mental-health services, to develop evidence-based treatment and preventive measures, to provide support for research in mental health, and to develop indicators to monitor progress. In October 2008, the World Health Organization launched the Mental Health Gap Action Programme, with the aim of scaling up the services for mental, neurological and substance-use disorders in all countries but especially those with low and middle incomes. The programme aims to develop evidence-based packages of care, psycho-social interventions and pharmacotherapy for tens of millions who could be treated for depression, schizophrenia and epilepsy, prevented from suicide, and begin to lead normal lives - even in very poor countries. While there is cause for optimism, much remains to be done. Most of all, there needs to be awareness amongst health providers and planners that mental health is an integral part of general health concerns, and that there can be no health without mental health.

Abstract
OBJECTIVES To ascertain the known burden of chronic obstructive pulmonary disease (COPD) in Africa and of spirometry use to indicate the possibility of further unpublished data becoming shortly available. METHOD Literature review. RESULTS Screening of 132 articles yielded 22 relevant articles, of which only six used spirometry based data. A total of 106 physicians in 34 countries were contacted and only 23 reported satisfactory use and availability of spirometry. CONCLUSIONS Current estimates of COPD burden in Africa are based on an unreliably small dataset. Acquisition of further data will require substantial investment in lung function equipment and training.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) affects millions worldwide. Despite advances in the treatments of other chronic diseases, little progress in decreasing COPD morbidity and mortality has been made. The death rate associated with COPD has doubled in 30 years. The presence of psychiatric comorbidities, such as anxiety and depression, has been linked to increased mortality, decreased functional status, and decreased quality of life. OBJECTIVE This review was undertaken to determine the state of the science of COPD, anxiety, and depression, and to identify nursing implications derived from these findings. CONCLUSION Although the prevalence of anxiety and depression among patients with COPD is significantly higher than the general population, there are serious barriers to the recognition and treatment of these comorbid conditions. Routine assessment and screening for anxiety and depression in all patients diagnosed with COPD should be considered.

Abstract
In the current study, the prevalence of the most common psychological disorders in COPD patients and their spouses was assessed cross-sectionally. The influence of COPD patients’ and their spouses’ psychopathology on patient health-related quality of life was also examined. The following measurements were employed: Forced expiratory volume in 1 second expressed in percentage predicted (FEV1%), Shuttle-Walking-Test (SWT), International Diagnostic Checklists for ICD-10 (IDCL), questionnaires on generic and disease-specific health-related quality of life (St. George’s Respiratory Questionnaire (SGRQ), European Quality of Life Questionnaire (EuroQol), a modified version of a Disability-Index (CDI)), and a screening questionnaire for a broad range of psychological problems and symptoms of psychopathology (Symptom-Checklist-90-R (SCL-90-R)). One hundred and forty-three stable COPD outpatients with a severity grade between 2 and 4 (according to the GOLD criteria) as well as 105 spouses took part in the study. The prevalence of anxiety and depression diagnoses was increased both in COPD patients and their spouses. In contrast, substance-related disorders were explicitly more frequent in COPD patients. Multiple linear regression analyses indicated that depression (SCL-90-R), walking distance (SWT), somatization (SCL-90-R), male gender, FEV1%, and heart disease were independent predictors of COPD patients’ health-related quality of life. After including anxiousness of the spouses in the regression, medical variables (FEV1% and heart disease) no longer explained disability, thus highlighting the relevance of spouses’ well-being. The results underline the importance of depression and anxiousness for health-related quality of life in COPD patients and their spouses. Of special interest is the fact that the relation between emotional distress and quality of life is interactive within a couple.

Abstract
BACKGROUND Approximately 60 million people in the United States live with one of four chronic conditions: heart disease, diabetes, chronic respiratory disease, and major depression. Anxiety and depression are very common comorbidities in COPD and have significant impact on patients, their families, society, and the course of the disease. METHODS We report the proceedings of a multidisciplinary workshop on anxiety and depression in COPD that aimed to shed light on the current understanding of these comorbidities, and outline unanswered questions and areas of future research needs. RESULTS Estimates of prevalence of anxiety and depression in COPD vary widely but are generally higher than those reported in some other advanced chronic diseases. Untreated and undetected anxiety and depressive symptoms may increase physical disability, morbidity, and health-care utilization. Several patient, physician, and system barriers contribute to the underdiagnosis of these disorders in patients with COPD. While few published studies demonstrate that these disorders associated with COPD respond well to appropriate pharmacologic and nonpharmacologic therapy, only a small proportion of COPD patients with these disorders receive effective treatment. CONCLUSION Future research is needed to address the impact, early detection, and management of anxiety and depression in COPD.

Abstract
Recent research using questionnaire measures has demonstrated high prevalence rates of mental disorders in chronic obstructive pulmonary disease (COPD). However, clinical interviews and clinical rather than healthy control groups have rarely been employed. The aim of the present study was to assess mental disorders in patients with COPD with advanced methodology, to identify moderating factors explaining mental co-morbidities and to compare results with a clinical control group without COPD. A standardized clinical interview (F-DIPS) and a range of questionnaires were used to assess mental disorders, perceived physical symptoms and cognitions in 20 hospitalized patients with mild-to-moderate COPD (mean FEV(1)/VC (%)=61.3). Results were compared with a hospitalized clinical control group without pulmonary dysfunction (CCG; N=20). Results showed that 55% of patients with COPD received a diagnosis of a mental disorder compared to 30% of CCG patients. All principal mental diagnoses in the COPD group were anxiety disorders (especially Panic Disorder with Agoraphobia), while CCG patients received a wider range of diagnoses (anxiety, pain, alcohol abuse). There was no systematic association between anxiety levels and respiratory function in the whole COPD group, but a positive correlation between anxiety levels and perceived physical symptoms (p<0.001) as well as negative cognitions (p<0.001 and p<0.05, respectively) for COPD patients with anxiety disorder (N=11). The present results confirm the high prevalence rate of anxiety in patients with COPD and suggest further that anxiety in COPD patients may be mediated by cognitive processes. These findings are discussed in terms of their implications for treatment.

Abstract
Depression is common in COPD patients. Around 40% are affected by severe depressive symptoms or clinical depression. It is not easy to diagnose depression in COPD patients because of overlapping symptoms between COPD and depression. However, the six-item Hamilton Depression Subscale appears to be a useful screening tool. Quality of life is strongly impaired in COPD patients and patients’ quality of life emerges to be more correlated with the presence of depressive symptoms than with the severity of COPD. Nortriptyline and imipramine are effective in the treatment of depression, but little is known about the usefulness of newer antidepressants. In patients with milder depression, pulmonary rehabilitation as well as cognitive-behavioral therapy are effective. Little is known about the long-term outcome in COPD patients with co-morbid depression. Preliminary data suggest that co-morbid depression may be an independent protector for mortality.

Abstract
BACKGROUND Psychiatric disorders are highly prevalent in patients with COPD. In general, psychiatric disorders are more common in women than in men. The extent to which women with COPD suffer from greater psychiatric and psychological morbidity is not known. The present cross-sectional study evaluated the prevalence of mood and anxiety disorders, levels of psychological distress, and quality of life in 62 women and 54 men with documented, stable COPD. METHODS All patients (n = 116) underwent a sociodemographic and medical history interview, followed by a structured psychiatric interview and standard spirometry. Patients also completed a battery of questionnaires measuring psychological distress and quality of life. RESULTS The overall prevalence of psychiatric disorders was 49%. Significantly more women than men met the diagnostic criteria for anxiety disorders (56% vs 35%), and a trend for greater levels of major depression in women was found (18% vs 7%). Women had significantly higher anxiety sensitivity and depressive symptoms compared to men but did not report more limitations in psychological functioning. Women also reported being less confident in their ability to control respiratory symptoms, and more daily physical limitations compared to men, despite having comparable COPD severity, dyspnea scores, and exacerbation rates. CONCLUSIONS Results indicate that psychiatric disorders are at least three times higher in COPD patients compared to the general population, and nearly two times higher in women than in men. Women also have greater psychological distress, worse perceived control of symptoms, and greater functional impairment. Greater efforts should be made to identify and treat psychiatric disorders in COPD patients, particularly in women.

Abstract
OBJECTIVE Although it has been suggested that depression is common in patients with chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), few studies on the association between chronic respiratory diseases and depression have been conducted in the community. METHOD Data from the baseline examination of two cohort studies, Mr and Ms Os, Hong Kong were used. Three thousand nine hundred and ninety-eight Hong Kong men and women aged 65 to 92 were recruited. Depression was assessed by face-to-face interview, using the short-form of a validated Chinese version of the Geriatric Depression Scale (GDS). Chronic respiratory disease was assessed by subjects' self reports of chronic respiratory disease (chronic bronchitis, emphysema and asthma) diagnosed by medical doctors. Adjusted odds ratios (ORs) and corresponding 95% confidence intervals (CI) for depression among subjects with chronic respiratory diseases relative to those without (controls) were calculated, after adjustments were made for potential confounders. RESULTS Chronic respiratory disease was associated with a higher prevalence of depressive disorders with an odds ratio of 1.58 (95% CI = 1.12-2.13) after adjustment was made for age, sex, cigarette smoking, alcohol drinking and history of cardiovascular diseases when compared with controls. For those subjects with self report of chronic respiratory disease and who screened positive for depression (n = 44), none were on antidepressants. Among subjects who screened positive for depression without self-report of chronic respiratory disease (n = 328), only 2.74% (n = 9) were on antidepressants. CONCLUSIONS We conclude that chronic respiratory disease is independently associated with depression in Chinese elderly. Moreover, depression in the elderly is under-treated in those with and without chronic respiratory disease. Clinicians, especially primary care physicians in the community, should be more aware of increased prevalence of depression in patients with chronic respiratory disease.

Abstract
OBJECTIVE The aim of this study was to review research on psychological characteristics in chronic obstructive pulmonary disease (COPD) patients and to summarize the findings of associations between psychological variables and various aspects of life, illness, and health in COPD patients. METHODS The following databases were searched: Medline, PsycINFO, and the Cochrane Library. RESULTS A total of 81 studies, published between 1968 and 2004, was identified. The reviewed studies indicated that patients suffering from COPD have a high prevalence of psychological disorders and may function at a reduced level of efficiency due to neuropsychological impairments. Psychological characteristics also seemed to be associated with functional disability and reduced quality of life. CONCLUSION Psychological characteristics are important variables that interact with physical symptoms, and they should be taken into account when treating COPD patients. More studies with rigorous methodological designs are needed to describe the role of psychological variables in COPD accurately and reliably.

Abstract
OBJECTIVE The authors used data from a prospective, population-based cohort study to examine: (a) whether the presence of chronic bronchitis predicts the subsequent onset of depression or anxiety, and (b) if the incidence of depressed or anxious cases was different for smokers compared with nonsmokers. MATERIALS AND METHODS For studying the relation between chronic bronchitis and anxiety or depression, we used data from respectively 4468 and 4520 respondents. RESULTS The number of incident anxious (19.1%, n = 17) and depressed (14.0%, n = 13) cases was highest in employees with chronic bronchitis compared with employees without respiratory complaints (4.3%, n = 189 and 3.3%, n = 145, respectively). The presence of chronic bronchitis was associated with a significant increase in anxious and depressed cases (odds ratio (OR) for anxiety = 5.09, 95% confidence interval (CI) 2.91, 8.89; OR for depression = 4.38, 95% CI 2.35, 8.16). The incidence of anxiety as well as depression was strongest in the smokers group (OR for anxiety = 8.94, 95% CI 4.08, 19.59; OR for depression = 7.56, 95% CI 3.37, 16.96). CONCLUSIONS This prospective study shows significantly higher levels of anxiety as well as depression in employees with chronic bronchitis. Results also seem to indicate that smoking cigarettes modifies this association, resulting in an increased risk of depression and anxiety in employees with chronic bronchitis who smoke.

Abstract
BACKGROUND The association between asthma and anxiety has been a subject of various studies in developed countries, but there has been little work done in this area in developing countries. The goal of this study is to determine whether asthmatics are more anxious than orthopaedic patients and healthy individuals. METHOD Fifty consecutive asthmatics were assessed. All completed a sociodemographic questionnaire, the General Health Questionnaire (GHQ--30) and the State Trait Anxiety Inventory (STAI--1 and 2). Healthy individuals (30) and orthopaedic patients (30) were also recruited as controls; they also completed the GHQ and the STAI--1 and 2. RESULTS No significant difference was found in the sociodemographic variables such as age, sex, occupation, and marital status. The asthmatics had a mean GHQ score of 4.2 (SD+/-4.6) while orthopaedic and healthy control groups scored 1.6 (SD+/-1.8) and 2 (SD+/- 1.8), respectively. There was a significant difference in the mean score of the index population (Asthmatics) and the comparison groups (F=7.09, DF=2/107, P=0.004). With GHQ, cutoff point of > or =5.34% of asthmatics scored above 5 while 10% and 13.3% of the orthopaedic patients and healthy controls each scored > or =5. A significant difference was obtained in the mean scores on the STAI--1 questionnaire (F=4.6, DF=2/107, P=.012) indicating state anxiety whereas there was no significant difference on the STAI-2 questionnaire (F= 1.2, DF=2/107, P=0.31). CONCLUSION Although asthmatics have higher anxiety compared to controls, this is not an inherent problem or trait among them.

Abstract
A review of the literature revealed high comorbidity of chronic obstructive pulmonary disease (COPD) and states of anxiety and depression, indicative of excess, psychiatric morbidity in COPD. The existing studies point to a prevalence of clinical significant symptoms of depression and anxiety amounting to around 50%. The prevalence of panic disorder and major depression in COPD patients is correspondingly markedly increased compared to the general population. Pathogenetic mechanisms remain unclear but both psychological and organic factors seem to play a role. The clinical and social implications are severe and the concurrent psychiatric disorders may lead to increased morbidity and impaired quality of life. Furthermore, the risk of missing the proper diagnosis and treatment of a concurrent psychiatric complication is evident when COPD patients are treated in medical clinics. Until now only few intervention studies have been conducted, but results suggest that treatment of concurrent psychiatric disorder leads to improvement in the physical as well as the psychological state of the patient. Panic anxiety as well as generalized anxiety in COPD patients is most safely treated with newer antidepressants. Depression is treated with antidepressants according to usual clinical guidelines. There is a need for further intervention studies to determine the overall effect of antidepressants in the treatment of anxiety and depression in this group of patients.

Abstract
OBJECTIVE This article reviews the prevalence of anxiety disorders in patients with chronic obstructive pulmonary disease (COPD) as well as the impact of comorbid anxiety on quality of life in patients with COPD. Published studies on three types of treatments for anxiety are then reviewed: psychopharmacology, psychotherapy, and pulmonary rehabilitation programs. MATERIALS AND METHODS A PubMed search was conducted of the literature from 1966 through 2002 using the keywords anxiety, chronic obstructive pulmonary disease, respiratory diseases, obstructive lung diseases, and pulmonary rehabilitation. Any articles that discussed the prevalence of anxiety symptoms or anxiety disorders among patients with COPD, the impact of anxiety on patients with COPD, or the treatment of anxiety in COPD patients were included in this review. RESULTS Anxiety disorders, especially generalized anxiety disorder (GAD) and panic disorder, occur at a higher rate in patients with COPD compared with the general population. Not surprisingly, anxiety has a significant and negative impact on quality of life of COPD patients. Nonetheless, few studies have examined pharmacological, psychotherapeutic, or pulmonary rehabilitation treatments for anxiety disorders in the context of COPD. Trials of nortriptyline, buspirone, and sertraline have been found to reduce symptoms of anxiety. Similarly, cognitive-behavioral programs that focus on relaxation and changes in thinking also produced declines in anxious symptoms. Finally, multicomponent pulmonary rehabilitation programs can also result in reductions in anxious symptoms. CONCLUSIONS Studies examining the treatment of anxiety disorders in patients with COPD are promising, yet their efficacy needs to be established. The long-term effects of treatment of anxiety disorders on quality of life of COPD patients have yet to be explored.

Abstract
The purpose of this investigation was to explore the psychiatric complications of liver cirrhosis in a Nigerian general hospital setting. The mental state of 31 consecutive patients with liver cirrhosis seen in a gastroenterology unit, from July 1996 to August 1998, was assessed using the 30-item General Health Questionnaire (GHQ-30) and Present State Examination (PSE) and compared with those of 20 hypertensive patients and 20 apparently healthy controls. The socio-demographic characteristics of patients with liver cirrhosis who developed psychiatric complications were compared with those without such complications. The mental status of the cirrhosis patients in the present study was also compared with those of Chronic Obstructive Pulmonary Disease (COPD) and hemodialysis patients in earlier studies. About fifty-five percent of all the liver cirrhosis patients developed diagnosable psychiatric morbidity. This was significantly higher than that of the hypertensive patients (15%) or healthy controls (5%) (P=0.0001). The psychiatric conditions were depressive episode, generalized anxiety disorder, delirium and adjustment disorder. No socio-demographic parameter had a significant effect on the mental state of the patients with liver cirrhosis. The same proportion (55%) of hemodialysis and a lower proportion (30%) of COPD patients compared with cirrhosis patients had psychiatric morbidity. We found a high rate of psychiatric morbidity in the patients with liver cirrhosis compared with those of hypertension and normal subjects. None of the socio-demographic variables considered was found to be associated with psychiatric complications in the liver cirrhosis patients. Poor medical conditions seem to be associated with high levels of psychiatric morbidity.
