Days out-of-role due to common physical and mental health problems: results from the São Paulo Megacity Mental Health Survey, Brazil

The lifetime costs of perinatal depression and anxiety in Brazil

BACKGROUND

Each year, an estimated 860,000 Brazilian women experience depression and anxiety perinatally. Despite well-known devastating impacts of these conditions on mothers and children, they remain neglected in low- and middle-income countries. Knowing the costs of untreated perinatal depression and anxiety can inform decision-making.

METHODS

Simulation modelling is used to examine lifetime costs of perinatal depression and anxiety for a hypothetical cohort of women and their children, followed until children are aged 40 years. Costs are measured from a societal perspective, including healthcare expenditure, productivity and health-related quality of life losses; 2017 data are taken from country-specific sources. Present values are calculated using a discount rate of 3 %.

RESULTS

Lifetime cost of perinatal depression and anxiety in Brazil are USD 4.86 billion or R$ 26.16 billion, including costs linked to poorer quality of life (USD 2.65 billion), productivity loss (USD 2.16 billion) and hospital care (USD 0.05 billion). When the costs associated with maternal suicide are included, total costs increase to USD 4.93 billion.

LIMITATIONS

Several costs could not be included in the analysis because of a lack of data. The study is reliant of longitudinal data on associations between perinatal depression and anxiety and impacts on mothers and children. Therefore, no causality can be inferred.

CONCLUSION

Our findings illustrate the economic rationale for investment in this area. This is the first study that estimates the costs of perinatal mental health problems in a low- or middle-income country setting.

Individual and population level estimates of work loss and related economic costs due to mental and substance use disorders in Metropolitan São Paulo, Brazil

BACKGROUND

We estimate work loss and economic costs due to mental and substance use disorders in the economically active population of the São Paulo Metropolitan Area, Brazil.

METHODS

The São Paulo Megacity Mental Health Survey assessed a population-based sample of 3,007 economically active residents using the Composite International Diagnostic Interview 3.0 and the World Health Organization Disability Assessment Schedule 2 to investigate, respectively, 12-month psychiatric disorders, work performance, and economic costs.

RESULTS

Absenteeism over the past 12 months was reported by 12.6%, and presenteeism by 14.7% (qualitative loss) and 13.1% (quantitative loss). Having any mental disorder was associated with 17.6 days of absenteeism and 37.7 days of reduced-qualitative and/or quantitative functioning. Fourteen mental disorders were significantly associated with work loss, with odds ratios ranging from 2.3 for adult separation anxiety to 40.4 for oppositional defiant disorder. At a population-level, oppositional defiant disorder, panic disorder, attention deficit disorder, and dysthymia contributed to the largest costs. The total annual economic costs were USD $83.2 billion/year, representing 6.1% of Brazil's Gross Domestic Product in 2007.

LIMITATIONS

Diagnosis of mental disorders was based on self-reported symptoms. Work loss assessment was restricted to 30 days before the interview and may not fully represents the annual real experience and symptoms of the respondents which would lead to an overestimation of the burden.

CONCLUSIONS

Mental disorders impose a great negative impact on work performance and functioning, with a consequent high economic burden, pointing to the need of implementing cost-effective interventions to prevent work loss.

Experiences of Violence Among Individuals With Schizophrenia in Indonesia: A Phenomenological Study

Individuals with schizophrenia have a greater risk of violence compared to the general population. However, the contribution of schizophrenia to violence is heavily debated and remains unclear. The purpose of the current phenomenological study was to explore experiences of violence among individuals with schizophrenia (N = 40, mean age = 35.6 years) in West Java, Indonesia. A purposive sampling method was used to select participants from main referral hospitals. Focus group discussions were held, revealing two main themes-victimization by nurses and victimization by family-and eight sub-themes. Sub-themes for victimization by nurses included physical violence, verbal violence, restraint, neglected basic human needs, and no informed consent. Sub-themes for victimization by family were physical violence, verbal violence, and deception. Patients with schizophrenia have the same rights as all other patients, including the right to dignified treatment, the right to informed consent, and the right to patient safety.

Multilevel Analysis of the Patterns of Physical-Mental Multimorbidity in General Population of São Paulo Metropolitan Area, Brazil

Chronic diseases are often comorbid and present a weighty burden for communities in the 21st century. The present investigation depicted patterns of multimorbidity in the general population and examined its association with the individual- and area-level factors in an urban sample of non-elderly adults of Brazil. Data were from the cross-sectional São Paulo Megacity Mental Health Survey, a stratified multistage area probability sampling investigation. Trained interviewers assessed mental morbidities and asked about physical conditions for 1,571 community-dwelling women and 1,142 men, aged between 18 and 64 years. Principal component analysis depicted patterns of physical-mental multimorbidity, by sex. Following, the patterns of multimorbidity were subjected to multilevel regression analysis, taking into account individual- and area-level variables. Three patterns of clustering were found for women: 'irritable mood and headache', 'chronic diseases and pain', and 'substance use disorders'. Among men, the patterns were: 'chronic pain and respiratory disease', 'psychiatric disorders', and 'chronic diseases'. Multilevel analyses showed associations between multimorbidity patterns and both individual- and area-level determinants. Our findings call for a reformulation of health-care systems worldwide, especially in low-resource countries. Replacing the single-disease framework by multi-disease patterns in health-care settings can improve the ability of general practitioners in the health-care of person-centred needs.

Which mental disorders are associated with the greatest impairment in functioning?

OBJECTIVE

The objective of this study is to estimate the comparative associations of mental disorders with three measures of functional impairment: the Global Assessment of Functioning (GAF); the number of days in the past 12 months of total inability to work or carry out normal activities because of emotions, nerves, or mental health (i.e., days out of role); and a modified version of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0).

METHODS

Secondary data analysis of the linked Mental Health Surveillance Study and the National Survey on Drug Use and Health (n = 5653), nationally representative population surveys conducted in the United States. Generalized linear models assessed the independent effects of mental disorders on each measure of functional impairment, controlling for mental disorder comorbidity, physical health disorders, and sociodemographic factors.

RESULTS

The results varied across measures of functional impairment. However, mood disorders generally tended to be associated with the greatest functional impairment, anxiety disorders with intermediate impairment, and substance use disorders with the least impairment. All 15 disorders were significantly associated with the GAF score in multiple regression models, eight disorders were significantly associated with the WHODAS score, and three disorders were significantly associated with days out of role.

CONCLUSIONS

Our results highlight the value of complementary measures of functional impairment.

Mental disorders and employment status in the São Paulo Metropolitan Area, Brazil: gender differences and use of health services

Abstract: Mental disorders are associated with employment status as significant predictors and as consequences of unemployment and early retirement. This study describes the estimates and associations of 12-month DSM-IV prevalence rates of mental disorders and use of health services with employment status by gender in the São Paulo Metropolitan Area, Brazil. Data from the São Paulo Megacity Mental Health Survey was analyzed (n = 5,037). This is a population-based study assessing the prevalence and determinants of mental disorders among adults, using the Composite International Diagnostic Interview. The associations were estimated by odds ratios obtained through binomial and multinomial logistic regression. This study demonstrates that having mental disorders, especially mood disorders, is associated with being inactive or unemployed among men and inactive among women, but only having a substance use disorder is associated with being unemployed among women. Among those with mental disorders, seeking health care services is less frequent within unemployed.

Dual burden of chronic physical diseases and anxiety/mood disorders among São Paulo Megacity Mental Health Survey Sample, Brazil

BACKGROUND

We assessed comorbid associations of 12-month DSM-IV mood/any anxiety disorders with chronic physical conditions within the São Paulo (SP) Megacity Mental Health cross-sectional survey of 5037 participants and explored whether strength of comorbid associations were modified when controlling for demographics.

METHODS

Chi-square tests and logistic regressions were used to examine comorbid associations of DSM-IV mood/anxiety disorders as measured by the WHO Composite International Diagnostic Interview (CIDI 3.0), and self-reported chronic physical conditions among adults from the SP Megacity Mental Health Survey.

RESULTS

Among those with any mood or anxiety disorder, chronic pain disorder was the most common physical condition (48.9% and 44.9%, respectively). Significant unadjusted odds ratios (OR) of comorbidity were found between diagnosis of two or more physical conditions and any mood disorders (3.08, 95% CI: 2.27-4.17), and any anxiety disorders (2.49, 95% CI: 1.95-3.17). Comorbidities remained significant when stratified by gender and controlling for marital status, household income, and education (latter two only included within anxiety models).

LIMITATIONS

These results cannot be generalized to other cities or rural populations. Homeless and institutionalized populations were not surveyed. Due to cross-sectional study design, the direction of association between chronic disease/chronic disease risk factors and mood disorders is unclear.

CONCLUSIONS

Dual burden of chronic physical conditions and mood/anxiety disorders is a notable problem among the São Paulo Megacity Survey population, with enhanced comorbidity experienced by community members with multiple physical conditions. Clinicians should consider these findings in understanding healthcare delivery for individuals suffering from both psychiatric disorders and chronic physical conditions.

Days out of role due to common physical and mental conditions: results from the Northern Ireland study of health and stress

PURPOSE

Days out of role due to health problems are a major source of lost human capital. We examined the relative importance of common physical and mental disorders in accounting for days out of role in Northern Ireland using the Northern Ireland Study of Health and Stress (NISHS) WHO World Mental Health (WMH) Survey.

METHODS

Face-to-face interviews were carried out with 4340 respondents (68.4 % response rate). Multiple regression analysis estimated associations of specific chronic physical disorders and mental disorders conditions and comorbidities with days out of role controlling for basic socio-demographics.

RESULTS

Overall, 16.8 % of respondents had at least one day totally out of role in the previous year. The strongest population-level effect was associated with arthritis, which accounted for 23.5 % of all days out of role. The strongest individual-level effects (days out of role per year) were associated with any anxiety disorder (32.3) arthritis (26.1) and pain (22.0). The 11 conditions accounted for 93 % of all days out of role, as measured by population attributable risk proportions (PARPs).

CONCLUSIONS

Common health conditions, including mental disorders, make up a large proportion of the number of days out of role and should be addressed to substantially increase overall productivity.

Social anxiety symptoms in alcohol-dependent outpatients: prevalence, severity and predictors

ABSTRACT Objectives High rates of comorbidity between social anxiety disorder (SAD) and alcohol use disorders have been reported, but the predictors of this comorbidity are poorly known and most studies involve primary SAD samples. The aims were to estimate the prevalence and severity of SAD symptoms among alcohol-dependent patients and to investigate sociodemographic and clinical factors associated with SAD comorbidity, including suicidal behaviors. Methods A cross-sectional study with 53 adults who were in treatment for alcohol dependence at a Brazilian public university outpatient service. Assessment instruments Social Phobia Inventory (SPIN), Short Alcohol Dependence Data and Beck Depression Inventory. Bivariate analyses between the categorical outcome (Probable SAD: SPIN ≥ 19) and explanatory variables were conducted. Correlates of SPIN total and subscales scores (dimensional outcomes) were also investigated. Results The diagnosis and treatment of alcohol dependence occurred, on average, 30 years after the onset of alcohol use and 39.6% of the 53 patients (37 men and 16 women) reported alleviation of social anxiety symptoms with alcohol use. Twenty-four (45.3%) patients presented probable SAD. These patients differed from non-SAD alcohol-dependent individuals by having lower income and higher frequency of depression, suicidal ideation, suicide plans and attempts. The SPIN subscales mostly associated with suicidal behaviors were social inadequacy and social inferiority. Conclusions SAD symptoms are common among help-seeking alcohol-dependent individuals and should be directly investigated and treated, since depression and suicidality are associated with this comorbidity. Prospective studies are needed to assess the impact of SAD treatment on the clinical course of alcohol dependence.

Days Out of Role Due to Mental and Physical Conditions: Results from the Singapore Mental Health Study

Objective

The aim of the current study was to evaluate the relative contributions of mental and physical conditions to days out of role among adults aged 18 years and above in Singapore.

Methods

The Singapore Mental Health Study was a cross-sectional epidemiological survey of a nationally representative sample of residents aged 18 years or older. Diagnosis of mental disorders was established using the Composite International Diagnostic Interview; while chronic physical conditions were established using a checklist. Days out of role were assessed using a WHO Disability Assessment Schedule item. Multivariate regression analyses were used to estimate individual-level and societal-level effects of disorders.

Results

Overall, 8.7% of respondents reported at least one day out of role, with a mean of 5.8 days. The most disabling conditions at the individual level were cancer (118.9 additional days), cardiovascular diseases (93.5), and bipolar disorder (71.0). At the societal level, cardiovascular diseases contributed the highest population attributable risk proportion (45%), followed by cancer (39.3%), and hypertension (13.5%).

Conclusions

Mental and physical conditions are linked to significant losses in productivity for society as well as role disability for individuals, underscoring the need to enhance prevention and intervention efforts to increase overall productivity and improve individual functioning.

Incremental health expenditure and lost days of normal activity for individuals with mental disorders: results from the São Paulo Megacity Study

Background

With the recent increase in the prevalence of mental disorders in developing countries, there is a growing interest in the study of its consequences. We examined the association of depression, anxiety and any mental disorders with incremental health expenditure, i.e. the linear increase in health expenditure associated with mental disorders, and lost days of normal activity.

Methods

We analyzed the results from a representative sample survey of residents of the Metropolitan Region of São Paulo (n = 2,920; São Paulo Megacity Mental Health Survey), part of the World Mental Health (WMH) Survey Initiative, coordinated by the World Health Organization and performed in 28 countries. The instrument used for obtaining the individual results, including the assessment of mental disorders, was the WMH version of the Composite International Diagnostic Interview 3.0 (WMH-CIDI 3.0) that generates psychiatric diagnoses according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria. Statistical analyses were performed by multilevel generalized least squares (GLS) regression models. Sociodemographic determinants such as income, age, education and marital status were included as controls.

Results

Depression, anxiety and any mental disorders were consistently associated with both incremental health expenditure and missing days of normal activity. Depression was associated with an incremental annual expenditure of R$308.28 (95 % CI: R$194.05-R$422.50), or US$252.48 in terms of purchasing power parity (PPP). Anxiety and any mental disorders were associated with a lower, but also statistically significant, incremental annual expenditure (R$177.82, 95 % CI: 79.68–275.97; and R$180.52, 95 % CI: 91.13–269.92, or US$145.64 and US$147.85 in terms of PPP, respectively). Most of the incremental health costs associated with mental disorders came from medications. Depression was independently associated with higher incremental health expenditure than the two most prevalent chronic diseases found by the study (hypertension and diabetes).

Conclusions

The fact that individuals with mental disorders had a consistent higher health expenditure is notable given the fact that Brazil has a universal free-of-charge healthcare and medication system. The results highlight the growing importance of mental disorders as a public health issue for developing countries.

Gender differences and disabilities of perceived depression in the workplace

BACKGROUND

Few studies have investigated gender difference and associated disability among workers. Comprehensive investigations concerning the occurrence and consequences of depression in workplace are scarce. The study aims to evaluate how workers perceive depression in workplace, as well as to examine depression-related disabilities by gender.

METHODS

This is a cross-sectional web-based survey of 1000 Brazilian workers recruited from Internet sources. Participants answered an online questionnaire about depressive symptoms and related consequences in the workplace.

RESULTS

Common symptoms attributable to depression were crying, loss of interest, and sadness. Almost one in five (18.9%) participants reported had ever been "labeled" by a health professional as suffering from depression. However, the majority of ever-depressed workers (73.5%) remained working. Performance-related impairments were reported by around 60% of depressed workers who continued working. Over half of them also complained about cognitive symptoms (concentration difficulties, indecisiveness, forgetfulness), with men reporting more cognitive dysfunctions than women. One in three workers had taken off work due to depression (mean 65.7 out-of-role days), with these periods being lengthier for men than women.

LIMITATIONS

Some depressive events might have occurred before working age, since the participants have self-reported the diagnosis of health professionals in past timeframe. The representativeness of recruited workers was reliant upon the availability of Internet service.

CONCLUSIONS

The findings suggest that identification and management of symptoms of depression should be set as a priority in worker׳s health care. General and gender-related strategies to handle depression in the workplace are recommended.

Occupational exposure to pesticides, nicotine and minor psychiatric disorders among tobacco farmers in southern Brazil

INTRODUCTION

Exposure to pesticides has been associated with psychiatric problems among farm workers, although there is still controversy as to chemical types, intensity and forms of exposure that represent risk factors for neuropsychological problems. Furthermore, tobacco workers are exposed to dermal absorption of nicotine, although its effect on mental health has not yet been studied.

OBJECTIVES

To identify the prevalence of minor psychiatric disorders (MPD) among tobacco farmers and associated factors, paying special attention to pesticide and nicotine exposure.

METHODS

This is a cross-sectional study with a representative sample of tobacco growers, characterizing economic indicators of the farms, socio-demographic factors, lifestyle habits and occupational exposures. Multivariate analysis was performed using a hierarchical Poisson regression model.

RESULTS

A total of 2400 tobacco farmers were assessed and MPD prevalence was 12%. MPD was higher among women (PR 1.4), workers aged 40 or over, tenants/employees (PR 1.8) and those who reported having difficulty in paying debts (PR 2.0). Low socioeconomic status was inversely associated with MPD prevalence. Tasks involving dermal exposure to pesticides showed risk varying between 35% and 71%, whereas tobacco growers on farms using organophosphates had 50% more risk of MPD than those not exposed to this kind of pesticide. The number of pesticide poisoning and green tobacco sickness episodes showed linear association with MPD.

CONCLUSIONS

The study reinforces the evidence of the association between pesticide poisoning and mental health disorders. It also points to increased risk of MPD from low socioeconomic status, dermal pesticide exposure as well as from exposure to organophosphates. Furthermore, the study reveals intense nicotine exposure as a risk for tobacco farmers' mental health.

Attitude and impact of perceived depression in the workplace

Information concerning the occurrence and consequences of depression in the workplace is scarce. This study estimates how workers perceive depression, to investigate depression-related disabilities, and management of depression in the workplace. This investigation is based on a cross-sectional web-based survey of 1,000 workers recruited from online sources. The participants were Brazilian workers, aged 16–64 years, current workers and managers, or who have worked within the past year. Subjects answered a 13-item questionnaire about depression, its related consequences in the workplace, and available resources to handle depression. Common symptoms attributable to depression were crying, loss of interest, and sadness. Almost one in five participants reported having ever been labeled by a doctor/medical professional as suffering from depression. However, the majority of ever-depressed workers (73.5%) remained working. Performance-related impairments were reported by around 60% of depressed workers who continued working. Over half of them also complained about cognitive symptoms (concentration difficulties, indecisiveness, forgetfulness). One in three workers had taken off work due to depression (mean 65.7 out-of-role days), with these periods being lengthier for men than women. Managers underestimated the number of days out-of-role (29.5 days). The findings suggested that identification and management of symptoms of depression should be set as a priority in worker’s health care.
