Validity and limitations of the Brazilian version of the Composite International Diagnostic Interview (CIDI 2.1)

Overall diet quality, food groups and mental health disorders among Brazilians older than 15 years old: Brazilian National Health Survey - 2019

BACKGROUND

Adherence to a nutrient-dense diet can have an impact on depression and other mental health issues. Little is known whether this is attributed to some or all components and how these differ in a country that is known to have a vast diversity of nutrient-dense foods. The aim was to examine whether there is a relationship between individual food groups with depression and other mental health disorders.

METHODS

Data was from 89,955 Brazilians from the National Health Survey. Mental health and diet were accessed using a screener questionnaire. Descriptive statistics and regression analyses were calculated.

RESULTS

Persons living with depression had significantly lower diet scores for vegetables/fruits (β = -0.08, 95 % CI -0.13, -0.02), grains/roots (β = -0.05; 95%CI (-0.07, -0.03)), beans (β = -0.03; 95%CI (-0.04, -0.01)) and higher scores for sweetened beverages (β = 0.04; 95%CI (0.01, 0.07)), sweets and sugars (β = 0.03; 95%CI (0.01, 0.05) and high fat/sodium products (β = 0.04; 9%CI (0.01, 0.07). Individuals living with other mental disorders showed lower scores for grains/roots (β = -0.03; 95%CI (-0.06, -0.01)) and higher scores for sweets and sugars (β = 0.06; 95%CI (0.03, 0.09)) and high fat/sodium products (β = 0.05; 95%CI (0.01, 0.09)).

CONCLUSION

People with mental health disorders are more likely to have an unhealthy diet. Relationships were slightly stronger with depression in particular food groups as other mental disorders. Further studies are needed to help in the prevention of these disorders.

The role of childhood cumulative trauma in the risk of lifetime PTSD: An epidemiological study

Cumulative trauma is usually devastating and can lead to severe psychological consequences, including posttraumatic stress disorder (PTSD). Exposure to various types of traumas, particularly during childhood, can be even more deleterious than the sheer number of events experienced. This epidemiological study is the first to investigate the impact of discrete childhood traumatic exposure on the risk of developing lifetime PTSD in a representative sample of the general population of the two biggest Brazilian cities. Participants were aged between 15 and 75 years old, living in São Paulo and Rio de Janeiro, Brazil, who had experienced traumatic events (N = 3,231). The PTSD diagnosis was assessed using the DSM-IV criteria through the version 2.1 of Composite International Diagnostic Interview. To operationalize childhood cumulative trauma, we considered the sum of 15 different childhood trauma categories that occurred before PTSD onset. The final multivariate logistic regression model indicated a strong relationship between the number of discrete types of childhood traumas and the likelihood of the lifetime PTSD development. The lifetime PTSD risk increased 28 % with each different type of childhood trauma when adjusted by confounds. Our study strengthens the evidence associating childhood cumulative trauma to increased lifetime PTSD risk.

Prevalence and correlates of passive and active suicidal ideation among students entering graduate courses

OBJECTIVE

to identify the prevalence and factors associated with passive and active suicidal ideation throughout life among students entering graduate courses.

METHOD

an analytical and cross-sectional study with a sample comprised of 321 students entering graduate courses. Multiple descriptive and inferential statistical analyses were performed.

RESULTS

the multivariate analyses indicated that passive and active suicidal ideation were similarly more prevalent among female students belonging to minority sexual orientations who engaged in daily physical activity ≤ 30 minutes/day and were victims of psychological violence in the past 12 months. Alcohol abuse, family relationships not impaired due to the demands imposed by stricto sensu graduate studies and low self-esteem were only associated with passive suicidal ideation. In turn, recent marijuana use in the last 30 days, poor interpersonal relationships with academic peers, and engagement in professional activities concomitantly with the demands imposed by graduate studies were only associated with active suicidal ideation.

CONCLUSION

high prevalence of lifetime passive and active suicidal ideation was identified among graduate students, and similarities and differences were verified between some associated factors for both outcomes.

Evidências de Validade da GAD-7 em Adolescentes Brasileiros

Resumo O objetivo deste estudo foi investigar evidências validade para a escala Generalized Anxiety Disorder (GAD-7) em adolescentes brasileiros, bem como validade concorrente para esta escala e apresentar a distribuição social do Transtorno de Ansiedade Generalizada (TAG). Participaram 302 adolescentes, com idades entre 15 e 19 anos, de ambos os sexos. Aplicou-se o questionário sociodemográfico, a GAD-7, a Hospital Anxiety and Depression Scale (HADS) e o Patient Health Questionnaire (PHQ-9). Os resultados da Análise Fatorial Exploratória (AFE) atestaram a unidimensionalidade da GAD-7 e indicaram consistência interna satisfatória. As evidências de validade concorrente apresentaram associações estatisticamente significativas e positivas entre a GAD-7 e as escalas PHQ-9 e HADS-A. Quanto à distribuição social, aproximadamente metade da amostra apresentou a ocorrência de sintomatologia positiva para TAG, sendo mais comum para o sexo feminino e em adolescentes mais jovens. Esses dados sugerem que a GAD-7 apresenta adequadas propriedades psicométricas para rastreamento de ansiedade em adolescentes.

Analysis of global prevalence of mental and substance use disorders within countries: focus on sociodemographic characteristics and income levels

This report presents the prevalence of mental and substance use disorders around the world discussing the impact of geographical, sociodemographic, and income characteristics on national epidemiological differences. We analysed data from the Institute of Health Metrics and Evaluation database published in 2019. The global prevalence of mental disorders was 13.0%, with higher prevalence of anxiety disorders rate (4.1%), followed by depressive disorders (3.8%, including major depressive disorder 2.49% and dysthymia 1.35%), intellectual disability (1.5%), ADHD (1.1%), conduct disorders (0.5%), bipolar disorders (0.5%), autism spectrum disorder s (0.4%), schizophrenia (0.3%), and eating disorders (0.2%, including bulimia nervosa 0.13% and anorexia nervosa 0.05%). The worldwide prevalence of substance-use disorders was 2.2%, not surprisingly, with higher prevalence of alcohol-use disorders (1.5%) than other drug-use disorders (0.8% total including: cannabis 0.32%; opioid 0.29%, amphetamine 0.10%; cocaine 0.06%). In general, high-income countries reported higher levels of mental and substance use disorders, with the exceptions of conduct and depressive disorders (no significant differences were found among low- and high-income countries), and intellectual disability (with higher prevalence in low-income countries). In regions of the America's prevalence rates of mental and substance use disorders were higher than in Europe. Western Pacific countries reported high levels of schizophrenia, and depressive disorders were highly prevalent in Africa as well as in the Americas. Intellectual disability reported higher rates in Eastern Mediterranean and South-East Asia. We discuss the cross-cultural variations in mental health expenditure and literacy as well as stigma-related factors and some of the environmental risk factors possibly related to these prevalence differences.

Health, social and criminal justice factors associated with dual diagnosis among incarcerated adults in Brazil and Australia: a cross-national comparison

PURPOSE

To estimate the prevalence of dual diagnosis and identify health, social and criminal justice factors associated with dual diagnosis among incarcerated adults in Australia and Brazil.

METHODS

We compared data from cross-sectional surveys of incarcerated adults (aged ≥ 18 years) in Australia and Brazil. Using data from linked emergency department, hospital, and in-prison medical records in the Australian sample, and from the Composite International Diagnostic Interview (CIDI) in the Brazilian sample, participants were categorised as having: (1) no mental disorder; (2) substance use disorder only; (3) mental illness only; or (4) dual diagnosis. A multivariate multinomial logistic regression model was fitted to identify factors associated with dual diagnosis in each country.

RESULTS

Approximately one quarter of participants in both Australia (22%) and Brazil (25%) met the diagnostic criteria for dual diagnosis. In both countries, dual diagnosis was associated with being female [relative risk (RR) = 2.25 (95% CI 1.47-3.43) Australia; RR = 2.59 (95% CI 1.79-3.74) Brazil], having a history of prior incarceration [RR = 2.99 (95% CI 1.99-4.48) Australia; RR = 2.27 (95% CI 1.57-3.29) Brazil], and having comorbid physical health problems [RR = 1.54 (95% CI 1.08-2.19) Australia; RR = 2.53 (95% CI 1.75-3.65) Brazil].

CONCLUSIONS

Despite differences in health, social, and criminal justice systems between Australia and Brazil, the prevalence of and factors associated with dual diagnosis in incarcerated adults appear to be similar in the two countries. A number of generalisable principles can be inferred and should be considered in health and criminal justice policy making.

Comorbidity in post-traumatic stress disorder: A population-based study from the two largest cities in Brazil

BACKGROUND

This study investigated the patterns of comorbidity between PTSD and depression, other anxiety disorders, alcohol-related disorders using the DSM-IV and ICD-10 criteria. The temporal sequence of the comorbid diagnoses was also investigated.

METHODS

We used data from a large population-based survey carried out between 2007 and 2008 in the two largest cities in Brazil: São Paulo and Rio de Janeiro.

RESULTS

Diagnoses of depression, other anxiety disorders, and alcohol-related disorder were more prevalent in the people with PTSD than in those without PTSD. Using the DSM-IV criteria, approximately 67% of cases presenting PTSD were also diagnosed with another mental disorder. The diagnosis category of other anxiety disorders presented the highest proportion of comorbidity (53%). Depression was found in 34% person with PTSD whilst alcohol-related disorders were observed in 7%. Considering the temporal relationship, the onset of comorbid depression was uniformly distributed through the periods before, within the same year and after PTSD's onset. When other anxiety disorders were comorbid with PTSD, in almost 90% of the cases the other anxiety disorders preceded PTSD. For comorbidity between of alcohol-related disorders and PTSD, in 50% of the cases alcohol-related disorders preceded the diagnosis of PTSD.

LIMITATIONS

The cross-sectional design imposes limitations on establishing a temporal relationship between the onset of psychiatric disorders due to memory bias.

CONCLUSIONS

Our findings indicate that among individuals presenting comorbid PTSD and other anxiety disorders, this diagnosis tend to precede PTSD. Comorbid cases are more frequent and more severe, and this should be taken into account in therapeutic research and clinical practice.

Correlated factors of depression among male and female inmates

INTRODUCTION

The prevalence of depression is high in the prison system, and the differences between sex regarding associated risk factors are still not clear. We analyzed the correlated factors of depression among incarcerated men and women in the state of São Paulo, Brazil.

METHODOLOGY

A cross-sectional study with stratified and multi-stage probabilistic sample was performed. Composite International Diagnostic Interview (CIDI) was applied for psychiatric diagnostic classification, as well as a questionnaire on criminal history with 1,192 men and 617 women. Lifetime prevalence of mental disorder was calculated, and association analysis performed by multinomial logistic regression stratified by sex. A dependent variable was categorized into depression, any other mental disorder and no mental disorder (reference).

RESULTS

The prevalence of depression was of 33.3% -(30.3 - 36.5) in women and 12.9% (11.1 - 15.0) in men. Depression was associated with disciplinary penalty, being in a stable relationship, physical health problems and history of infringement in adolescence in men. Regarding other mental illnesses, the correlated factors were historical transgression during adolescence and re-offense. Among women, depression was associated with physical health problems, drug crimes, violent crimes and being imprisoned.

DISCUSSION

Results confirmed the differences between associated factors with depression regarding sex.

CONCLUSION

Differences in the profile between men and women require effective specialized programs, considering the need for coping strategies for incarcerated men and health-related rehabilitation for women with depression.

Use of mental health services by community-resident adults with DSM-IV anxiety and mood disorders in a violence-prone area: São Paulo, Brazil

BACKGROUND

While under-use of mental health services by adults with anxiety and/or depression is well established, use in a violence-prone area, and as a function of diagnosis and personality characteristics such resilience, is little known. We examine the sociodemographic and personality characteristics (specifically resilience), associated with use of mental health services in a violence-prone city by those with anxiety, depression, and their comorbidity.

METHODS

The structured Composite International Diagnostic Interview was used to identify 12-month DSM-IV- and ICD-10-defined anxiety and depression in a cross-sectional, representative, community-resident sample age 15-75y (N = 2536) in São Paulo, Brazil, and their use of mental health services. Resilience was determined by the Wagnild and Young scale. Analyses, using weighted, design-corrected statistical tests, included frequency measures and multivariable logistic regression.

RESULTS

Mental health services were used by 10% with only anxiety, 22% with only depression, and 34% with comorbidity, with odds of use in controlled analyses doubling from anxiety to depression to comorbidity. Use was significantly higher among those who were white, older (age >30 years, with substantial social support, low resilience, living in low homicide rate areas; use was not affected by experience of traumatic events. Psychiatrists, general practitioners, and psychologists were the primary providers.

LIMITATIONS

Cross-sectional design CONCLUSIONS: Contrary to expectation, use was greater among residents of lower homicide areas, and was not associated with personal traumatic experience. This may reflect increased immunity to violence in higher homicidal rate areas, lower resilience, and poorer access to services. Increased access to mental health services is needed.

12-month prevalence and concomitants of DSM-IV depression and anxiety disorders in two violence-prone cities in Brazil

BACKGROUND

Estimating 12-month prevalence of depression, anxiety, and comorbid anxiety/depression in noninstitutionalized adults (age 15-75) in two violence-prone cities.

METHODS

The Composite International Diagnostic Interview v2.1 (Portuguese), administered in population-representative surveys (age 15-75) in São Paulo (N = 2536) and Rio de Janeiro (N = 1208), yielded 12-month prevalence of violent events experienced, and DSM-IV diagnoses of depression and anxiety, which were classified into mutually exclusive groups: 1) no anxiety/depression; 2) anxiety only; 3) depression only; 4) comorbid anxiety/depression. Weighted analyses estimated 12-month prevalence, multinomial logistic regression compared the demographic characteristics of the diagnosis groups, and association with experienced violence.

RESULTS

Twelve-month prevalence of anxiety alone, depression alone, and comorbid anxiety/depression was 12.7% (of whom 24.9% were also depressed), 4.9% (of whom 46.2% had anxiety), and 4.2% respectively for São Paulo; and 12.1% (18.2% of whom were depressed), 4.6% (37.0% with anxiety), and 2.7% respectively for Rio de Janeiro. All conditions were approximately twice as prevalent in women than in men in both cities. In São Paulo, comorbidity was associated with age under 60, depression alone was more prevalent among 30-59 year olds, but in 23-29 year-olds in Rio de Janeiro. Exposure to violence increased the odds of anxiety, depression, and their comorbidity. With rare exception, marital status, education, and race/ethnicity were not associated with anxiety, depression, or their comorbidity.

LIMITATIONS

Cross-sectional design.

CONCLUSIONS

Prevalence rates for all conditions were high, and particularly associated with exposure to violence. Means to ameliorate violence, and its mental health effects, particularly for women, are needed.

A cross-sectional study to compare levels of psychiatric morbidity between young people and adults exposed to violence in a large urban center

BACKGROUND

Teenagers and young adults are more exposed to violence and traumatic events than adults, and these factors can be associated with mental disorders. This paper aims at investigating whether young people are more exposed to violence and traumatic events and to compare pattern of mental disorders with adults.

METHODS

Cross-sectional study using the Composite International Diagnostic Interview, conducted between 2007 and 2008 with a randomly selected sample of 15 to 75 year-old residents of São Paulo, Brazil.

RESULTS

Two thousand five hundred thirty-six participants were divided into two groups: 1096 (43.2 %) young people (15 to 24 years), and 1440 (56.8 %) adults (25 to 75 years). 12-month exposure to traumatic events was higher among young people (32.1 % vs. 20.6 %; p < 0.001). Assaultive violence was reported by 13.4 % of young people and 8.6 % of adults (p = 0.012); 20.1 % of young people and 13 % of adults reported suffering other injury or shocking events (p < 0.001); sudden death/life threatening illness of a close person was declared by 6.1 % of young people and 3.2 % of adults (p = 0.017). Prevalence of alcohol related disorders was higher among young people (5.4 % vs. 2.5 %; P = 0.032); depressive disorders were more prevalent among adults (9.0 % vs. 4.7 %; P = 0.004). Alcohol related disorders were associated to assaultive violence among young people (OR = 3.4; 95 % CI = 1.36 to 8.52; p = 0.004) and adults (OR = 2.38; 95 % CI = 1.23 to 4.61; p = 0.002). Phobic/anxiety disorders were associated to other injury or shocking events among young people (OR = 1.28; 95 % CI = 0.67 to 2.44; p = 0.025). Major depressive disorder was associated to assaultive violence among young people (OR = 2.27; 95 % CI = 1.09 to 4.74; p = 0.004) and adults (OR = 1.28; 95 % CI = 0.85 to 1.93; p = 0.009).

CONCLUSION

Exposure to violence and traumatic events was higher among young people. Alcohol related disorders, depression and phobic/anxiety disorders were significantly higher among young people exposed to traumatic events. Despite the study design, high exposure to violence and traumatic events in this age group can be considered important factors in triggering mental disorders in this vulnerable age period.

Anxiety and depressive disorders in elderly with chronic dizziness of vestibular origin

Introduction

Dizziness is one of the most prevalent symptoms in the elderly. Anxiety and depression are common in dizzy adult patients, but there is scarce information about comorbidity between vestibular disturbances and psychiatric disorders in the aged.

Objective

To assess the prevalence of anxiety and depression disorders in elderly with chronic dizziness of vestibular origin.

Methods

Transversal study that used the Brazilian version of the Composite International Diagnostic Interview 2.1 to assess anxiety and depressive disorders in elderly patients (≥60 years old) with chronic dizziness.

Results

Most of the 44 patients included in the study were female (88.6%) with a mean age of 71 years (±7.5), 68.1% had experienced dizziness for 1 year or more. The most prevalent diagnosis was benign paroxysmal positional vertigo (52.3%). The prevalence of generalized anxiety disorder and specific phobias during life were 29.5% and 22.7%, respectively, and, in the last 12 months, 18.2% and 15.9%. There was no patient with panic disorder, agoraphobia or social phobia. The prevalence of depressive disorder during life was 45.4%, and, in the last 12 months, were 11.3%.

Conclusion

Aged patients with chronic dizziness had high prevalence of some mental disorders.

Suicide in late-life depression with and without comorbid anxiety disorders

OBJECTIVE

Comorbid anxiety in depression increases the risk of suicidal ideation and behavior, although data on death by suicide are scarce. We compared characteristics of depressed elderly patients with and without anxiety disorders who died by suicide.

METHODS

From a 16-year clinical survey of all suicides in the UK (n = 25,128), we identified 1909 cases aged ≥60 years with a primary diagnosis of depression and no comorbidity other than anxiety disorders. Clinical characteristics of cases with (n = 333, 17.4%) and without (n = 1576) comorbid anxiety disorders were compared by logistic regression adjusted for demographic differences.

RESULTS

Compared with cases without comorbid anxiety disorders, cases with comorbid anxiety disorders were more likely to have a duration of illness over 1 year (OR(1-5 years)  = 1.4 [95% CI: 1.0-1.9], p = 0.061; OR(≥5 years)  = 1.4 [95% CI: 1.6-2.8], p < 0.001), were more frequently prescribed psychotropic drugs other than antidepressants, lithium, and antipsychotics (OR = 2.1 [95% CI: 1.6-2.7], p < 0.001) and were more distressed during their last contact with services (OR = 1.3 [95% CI: 1.0-1.7], p = 0.037). In contrast, clinicians estimated the immediate and long-term suicidal risks lower in those with comorbid anxiety disorders (OR = 0.6 [95% CI: 0.3-0.9], p = 0.011 and OR = 0.7 [95% CI: 0.6-1.0], p = 0.028, respectively).

CONCLUSION

Among depressed suicide cases, a comorbid anxiety disorder was identified in one out of six cases and associated with a higher prevalence of several suicide risk factors. This is important, as the detection of anxiety disorders comorbid to depression seems rather low and even when recognized clinicians rated such individuals as at low suicide risk.

Conditional risk for posttraumatic stress disorder in an epidemiological study of a Brazilian urban population

INTRODUCTION

Conditional risk for PTSD is the risk of developing PTSD after exposure to traumatic events. This epidemiological study of the general urban population from the two largest cities in Brazil reports exposure to traumatic events; conditional risk for PTSD; and proportion/estimated number of PTSD cases secondary to each type of traumatic event.

METHOD

Cross-sectional study of general population (15-75 y.o.) from Rio de Janeiro and São Paulo. PTSD was assessed through Composite International Diagnostic Interview 2.1.

RESULTS

Our main findings, from 3744 participants, were: 1) high prevalence of traumatic events (86%), urban violence being the most common; 2) conditional risk for PTSD was 11.1%; 3) women (15.9%) have overall conditional risk 3 times higher than men (5.1%); 4) war-related trauma (67.8%), childhood sexual abuse (49.1%) and adult sexual violence (44.1%) had the highest conditional risks; 5) 35% of PTSD cases (estimated 435,970 individuals) were secondary to sudden/unexpected death of a close person, and 40% secondary to interpersonal violence.

CONCLUSIONS

Brazilian urban population is highly exposed to urban violence, and overall conditional risk for PTSD was 11.1%. Violence prevention and enhancement of resilience should be part of public policies, and mental health sequelae of trauma should be better recognized and treated.

Subjective distress in a representative sample of outpatients with psychotic disorders

BACKGROUND

The affective burden of psychotic disorder has been increasingly recognised. However, subjective reports of distress and its covariates, especially those related to service use, remain under-investigated in patients with psychosis.

METHODS

This study investigated subjective distress and its covariates in a representative sample of 401 outpatients with a confirmed diagnosis of psychotic disorders in Brazil. Distress was assessed using the corresponding domain of a standardised measure of need - the Camberwell Assessment of Need.

RESULTS

Distress was reported as a need by 165 (41%) patients, being met in 78 (20%) and unmet in 87 (22%). Hierarchical logistic regression showed that the presence of distress as a need was predicted by attendance at psychotherapy (OR=3.49, CI=1.62-7.53), presence of suicidal ideation (OR=2.89, CI=1.75-4.79), non-attendance at psychosocial rehabilitation (OR=2.84, CI=1.31-6.19), and higher psychopathology (OR=1.09, CI=1.06-1.12). An unmet need was predicted by family not accompanying patients to treatment (OR=2.60, CI=1.05-6.44) and higher psychopathology (OR=1.05, CI=1.02-1.09).

LIMITATION

The use of a cross-sectional design and a single questionnaire domain to evaluate distress are the main limitations.

CONCLUSIONS

Subjective distress is a common unmet need in psychosis, and can be treated. The main clinical implication is that subjective distress in psychosis may be impacted on by family engagement and psychosocial interventions.

Psychotropic Drug Use in São Paulo, Brazil--An Epidemiological Survey

OBJECTIVE

To estimate the prevalence of one month psychotropic drug use in São Paulo, Brazil, and to assess the gap treatment between the presence of mental disorders and psychotropic drug users.

METHOD

A probabilistic sample of non-institutionalized individuals from the general population of São Paulo (n = 2336; turnout: 84.5%) who were 15 years or older were interviewed by a trained research staff, applying the Composite International Diagnostic Interview 2.1 (CIDI WHO) (depression, anxiety-phobia, OCD\PTSD, alcoholism sections), and an inventory investigating psychotropic drug use during the 12-month and one-month periods immediately preceding the interview. Logistic models were fitted to investigate associations between psychotropic drug use as well as socio-demographic and clinical variables.

RESULTS

The one month prevalence of psychotropic drug use in São Paulo was 5.89%, the most commonly used drugs were antidepressants (3.15%) and tranquilizers (2.67%). A higher consumption of psychotropic drugs (overall, antidepressants and tranquilizers) was observed among women (OR:2.42), older individuals (OR:1.04), individuals with higher levels of formal education (1.06), and individuals with a family (OR:2.29) or personal history of mental illness (OR:3.27). The main psychotropic drug prescribers were psychiatrists (41%), followed by general practitioners (30%); 60% of psychotropic drugs were obtained through a government-run dispensing program. Most individuals who obtained a positive diagnosis on the CIDI 2.1 during the previous month were not using psychotropic medication (85%). Among individuals with a diagnosis of moderate to severe depression, 67.5% were not on any pharmacological treatment.

CONCLUSION

There is a change in the type of psychotropic more often used in São Paulo, from benzodiazepines to antidepressants, this event is observed in different cultures. The prevalence of use is similar to other developing countries. Most of the patients presenting a psychiatric illness in the month prior to testing were not receiving any sort of psychiatric medication. This may be explained by a failure to identify cases in primary care, which could be improved (and access to treatment could be facilitated) if professionals received more specialized training in managing cases with mental health problems.

Drug-related disorders and the criminal and clinical background of the prison population of São Paulo State, Brazil

Objective

To analyze the association between drug (DAD) and alcohol (AAD) abuse and dependency and criminal and clinical background by gender of prisoners in São Paulo, Brazil.

Method

Cross-sectional study, random sample stratified by administrative district, from which prisons and prisoners were selected via random, multistage sampling. Psychiatric diagnoses were made with the CIDI 2.1. Lifetime prevalence and 95% CI were calculated and adjusted via analysis of complex samples. Multinomial logistic regression analysis was carried out with four categories of dependent variables: presence AAD; presence DAD; presence of another mental disorder; no mental disorders. For female alcohol and drug abuse and dependency (ADAD) were combined into a single category.

Results

The sample was composed by 1809 interviewed prisoners (1192 men and 617 women). Prevalence of DAD and AAD was 25.2% and 15.6%, respectively, among female prisoners, and 26.5% and 18.5% among males. Male prisoners with DAD were more likely to have a criminal record as an adolescent (OR 2.17), to be a repeat offender (OR 2.85), and to have committed a property crime (OR 2.18). Prisoners with AAD were repeat offenders (OR 2.18). Among female prisoners, ADAD was associated with repeat offenses (OR 3.39), a criminal record as an adolescent (OR 9.24), a clinical or infectious condition (OR 5.09), another health problem (OR 3.04), and violent crime (OR 2.5).

Conclusion

The study confirmed an association between drug-use disorders and the criminal and clinical background in the study population. Prisoners with such disorders were more likely to be repeat offenders and to have a criminal record as adolescents. Among female prisoners disorders were also associated with violent crime and health problems, while among males they were associated with property crime. These patterns in clinical and criminal backgrounds illustrate the need for social rehabilitation programs and specific medical treatment for prison populations.

Resilience to trauma in the two largest cities of Brazil: a cross-sectional study

BACKGROUND

Resilience is a dynamic process involving the interaction between intrapsychic and social factors of risk and protection. For resilience to be recognized there must be a significant threat to the individual, such as a traumatic event, and a good quality of adjustment. The aim of this study was to identify predisposing factors and possible mechanisms associated with resilience to traumatic events in the general population.

METHODS

We conducted a cross-sectional study with a random sample, aged 15-75 years, living in the two largest cities in Brazil, who were exposed to trauma (N = 3,231). Positive adaptation to trauma was defined as the lifetime absence of anxiety (including posttraumatic stress disorder), depression and alcohol related disorders in the presence of at least one traumatic event. Logistic regression models predicting resilience were used to estimate the incidence density ratio. This measure expresses the extent to which the rate of resilience differs from the exposed group to the non-exposed group. Moreover, we explored the relationship between positive/negative affect and resilience, using linear regression models.

RESULTS

Male gender was a predisposing factor to positive adaptation (incidence density ratio [IDR] = 1.34; p < 0.001). There was an inverse linear relationship between childhood violence and resilience (IDR = 0.67; 0.53; 0.19; p < 0.001). Our findings suggest that the absence of parental mental disease (IDR = 1.35; p = 0.07) also predisposes individuals to positive adaptation.

CONCLUSIONS

This study provides results that help to identify vulnerable groups and protective factors that may lead to a positive adaptation following traumatic experiences.

The joint structure of major depression, anxiety disorders, and trait negative affect

BACKGROUND

Dimensional models of psychopathology demonstrate that two correlated factors of fear and distress account for the covariation among depressive and anxiety disorders. Nevertheless, these models tend to exclude variables relevant to psychopathology, such as temperament traits. This study examined the joint structure of DSM-IV-based major depression and anxiety disorders along with trait negative affect in a representative sample of adult individuals residing in the cities of São Paulo and Rio de Janeiro, Brazil.

METHODS

The sample consisted of 3,728 individuals who were administered sections D (phobic, anxiety and panic disorders) and E (depressive disorders) of the Composite International Diagnostic Interview (CIDI) 2.1 and a validated version of the Positive and Negative Affect Schedule. Data were analyzed using correlational and structural equation modeling.

RESULTS

Lifetime prevalence ranged from 2.4% for panic disorder to 23.2% for major depression. Most target variables were moderately correlated. A two-factor model specifying correlated fear and distress factors was retained and confirmed for models including only diagnostic variables and diagnostic variables along with trait negative affect.

CONCLUSIONS

This study provides support for characterization of internalizing psychopathology and trait negative affect in terms of correlated dimensions of distress and fear. These results have potential implications for psychiatric taxonomy and for understanding the relationship between temperament and psychopathology.

Prevalence of mental disorders among prisoners in the state of Sao Paulo, Brazil

Objective

To determine the prevalence of psychiatric disorders in the prison population in the State of São Paulo, Brazil.

Methods

Through stratified random sampling, 1.192 men and 617 women prisoners were evaluated for the presence of psychiatric disorders by the Composite International Diagnostic Interview, 2.1 version, according to definitions and criteria of International Classification of Diseases (ICD-10). The prevalence estimates of mental disorders and their respective 95% confidence intervals were calculated and adjusted for sample design through complex sample analysis.

Results

Lifetime and 12-month prevalence rates differed between genders. Lifetime and 12-month prevalence of any mental disorder was, respectively, 68.9% and 39.2% among women, and 56.1% and 22.1% among men. Lifetime and 12-month prevalence of anxious-phobic disorders was, respectively, 50% and 27.7% among women and 35.3% and 13.6% among men, of affective disorders was 40% and 21% among women and 20.8% and 9.9% among men, and of drug-related disorders was 25.2% and 1.6% among women and 26.5% and 1.3% among men. For severe mental disorders (psychotic, bipolar disorders, and severe depression), the lifetime and 12-month prevalence rates were, respectively, 25.8% and 14.7% among women, and 12.3% and 6.3% among men.

Conclusions

This is the first large-scale epidemiological study performed with the prison population in Brazil, revealed high rates of psychiatric disorders among men and women. Many similarities, as well as some differences, were found between our results and those of studies conducted in other countries. The differences observed are more likely due to the peculiarities of the prison systems in each country than to the diagnostic criteria adopted in the studies. This fact reinforces the importance of conducting such studies as part of planning and development of appropriate policies for the particular mental health needs of specific prison populations.

Epidemiology of psychotropic drug use in Rio de Janeiro, Brazil: gaps in mental illness treatments

Objective

Estimate the prevalence of psychotropic drugs use in the city of Rio de Janeiro, Brazil, and establish its relationship with the presence of mental disorders.

Methods

A probabilistic sample of non-institutionalized individuals, from the general population of Rio de Janeiro (n = 1208;turn out:81%), 15 years or older, who were interviewed using the Composite International Diagnostic Interview 2.1 (depression, anxiety-phobia, OCD\PTSD, alcoholism sections), and asked about their psychotropic use during a 12 and one-month period before the interview. Data were collected between June/2007-February/2008.The prevalence was estimated with a confidence interval of 95%. The associations between psychotropics use and mental disorders were analyzed through a logistic regression model (Odds Ration – OR).

Results

The one-month prevalence of psychotropic drug use was 6.55%, 3.19% for men and 9.13% for women. Antidepressants were the most frequently used drug (2.78%), followed by anorectics (1.65%), tranquilizers (1.61%) and mood stabilizers (1.23%). General practitioners issued the highest number of prescriptions (46.3%), followed by psychiatrists (29.3%); 86.6% of the psychotropic drugs used were paid for by the patient himself. Individuals with increased likelihood of using psychotropic drugs were those that had received a psychiatric diagnosis during a one-month period before the study (OR:3.93), females (OR:1.82), separated/divorced (OR:2.23), of increased age (OR:1.03), with higher income (OR:2.96), and family history of mental disorder (OR:2.59); only 16% of the individuals with a current DSM IV diagnosis were using a psychotropic drug; 17% among individuals with a depression-related diagnosis and 8% with Phobic Anxiety Disorders-related diagnosis used psychotropics.

Conclusion

Approximately 84% of individuals displaying some mental disorder did not use psychotropic drugs, which indicates an important gap between demand and access to treatment. A significant failure is evident in the health system for patients with mental disorders; this could be due to health workers' inability to recognize mental disorders among individuals.

The impact of epidemic violence on the prevalence of psychiatric disorders in Sao Paulo and Rio de Janeiro, Brazil

Background

Violence and other traumatic events, as well as psychiatric disorders are frequent in developing countries, but there are few population studies to show the actual impact of traumatic events in the psychiatric morbidity in low and middle-income countries (LMIC).

Aims

To study the relationship between traumatic events and prevalence of mental disorders in São Paulo and Rio de Janeiro, Brazil.

Methods

Cross-sectional survey carried out in 2007–2008 with a probabilistic representative sample of 15- to 75-year-old residents in Sao Paulo and Rio de Janeiro, Brazil, using the Composite International Diagnostic Interview.

Results

The sample comprised 3744 interviews. Nearly 90% of participants faced lifetime traumatic events. Lifetime prevalence of any disorders was 44% in Sao Paulo and 42.1% in Rio de Janeiro. One-year estimates were 32.5% and 31.2%. One-year prevalence of traumatic events was higher in Rio de Janeiro than Sao Paulo (35.1 vs. 21.7; p<0.001). Participants from Rio de Janeiro were less likely to have alcohol dependence (OR = 0.55; p = 0.027), depression (OR = 0.6; p = 0.006) generalized anxiety (OR = 0.59; p = 0.021) and post-traumatic stress disorder (OR = 0.62; p = 0.027). Traumatic events correlated with all diagnoses – e.g. assaultive violence with alcohol dependence (OR = 5.7; p<0.001) and with depression (OR = 1.7; p = 0.001).

Conclusion

Our findings show that psychiatric disorders and traumatic events, especially violence, are extremely common in Sao Paulo and Rio de Janeiro, supporting the idea that neuropsychiatric disorders and external causes have become a major public health priority, as they are amongst the leading causes of burden of disease in low and middle-income countries. The comparison between the two cities regarding patterns of violence and psychiatric morbidity suggests that environmental factors may buffer the negative impacts of traumatic events. Identifying such factors might guide the implementation of interventions to improve mental health and quality of life in LMIC urban centers.

Accuracy of the Composite International Diagnostic Interview (CIDI 2.1) for diagnosis of post-traumatic stress disorder according to DSM-IV criteria

The objective was to study the accuracy of the post-traumatic stress disorder (PTSD) section of the Composite International Diagnostic Interview (CIDI 2.1) DSM-IV diagnosis, using the Structured Clinical Interview (SCID) as gold standard, and compare the ICD-10 and DSM IV classifications for PTSD. The CIDI was applied by trained lay interviewers and the SCID by a psychologist. The subjects were selected from a community and an outpatient program. A total of 67 subjects completed both assessments. Kappa coefficients for the ICD-10 and the DSM IV compared to the SCID diagnosis were 0.67 and 0.46 respectively. Validity for the DSM IV diagnosis was: sensitivity (51.5%), specificity (94.1%), positive predictive value (9.5%), negative predictive value (66.7%), misclassification rate (26.9%). The CIDI 2.1 demonstrated low validity coefficients for the diagnosis of PTSD using DSM IV criteria when compared to the SCID. The main source of discordance in this study was found to be the high probability of false-negative cases with regards to distress and impairment as well as to avoidance symptoms.

The structure of common mental disorders in incarcerated offenders

BACKGROUND

Dimensional models of mental disorders in community-based epidemiological samples have consistently demonstrated correlated externalizing and internalizing factors underlying common mood, anxiety, and substance use disorders. However, such analyses tend to exclude populations such as prisoners and psychiatric inpatients. As these samples have been shown to have a much higher prevalence of mental disorders and comorbidity than community samples, whether the internalizing-externalizing structure of psychopathology will replicate in such samples is unknown.

OBJECTIVES

The current study examined the consistency of this structure in a representative sample of 1837 prisoners through structural equation modeling of 10 common mental disorders along with a record-based index of antisocial behavior.

METHOD

Diagnoses were determined by administration of the Composite International Diagnostic Interview 2.1. Data were analyzed via tetrachoric correlations using the weighted least squares estimator in exploratory and confirmatory factor analyses.

RESULTS

Results revealed that a two-factor solution, entailing correlated internalizing and externalizing factors, displayed the best fit to the data.

CONCLUSIONS

This study provides additional support for characterizing common psychopathology in terms of internalizing and externalizing factors.

Depressão durante a gestação e os desfechos na saúde do recém-nascido: coorte de mães atendidas em unidade básica de saúde

OBJETIVO: Descrever a associação entre depressão durante a gestação e os efeitos no recém-nascido (baixo peso ao nascer e prematuridade). MÉTODOS: Foi realizado um estudo de coorte, com 100 gestantes atendidas entre março e setembro de 2011 em uma unidade de atenção básica de saúde de Nova Iguaçu. As gestantes responderam sobre características sociodemográficas, condições médicas/obstétricas, eventos estressantes e apoio social. A depressão foi avaliada por meio do Composite International Diagnostic Interview (CIDI). Após o período do pós-parto, as mães responderam às questões sobre baixo peso e prematuridade ao nascer. RESULTADOS: A prevalência da depressão na gravidez foi de 18% (IC95%: 12,2-23,8). Fatores associados com desfecho neonatal foram depressão gestacional (OR: 6,60 IC: 1,51-28,91) e uso de álcool (OR: 8,75 IC: 1,10-69,71). CONCLUSÃO: As implicações do presente estudo para a prática enfatizam a necessidade de triagem para depressão durante a gestação.

Reduced cerebellar left hemisphere and vermal volume in adults with PTSD from a community sample

BACKGROUND

Traumatic events exposure is a necessary condition for developing posttraumatic stress disorder (PTSD), but not all individuals exposed to the same trauma will develop PTSD. Human studies have suggested that the cerebellum is involved in human fear perception, anticipation, and recollection. In this context, the current study evaluated whether cerebellar volume is associated with PTSD.

METHODS

Eighty-four victims of violence, 42 who fulfilled the DSM-IV-TR criteria for PTSD and 42 resilient controls, were identified through an epidemiologic survey conducted in the city of São Paulo. Subjects were evaluated using the Clinician-Administered PTSD Scale (CAPS), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Early Trauma Inventory (ETI). All subjects underwent a magnetic resonance imaging (MRI) scan to evaluate their cerebellar hemispheres and vermis.

RESULTS

PTSD subjects had relative smaller left hemisphere (p = 0.04) and vermis (p < 0.01) volumes persisted after controlling for gender, age, and brain volume. In PTSD group, left cerebellar hemisphere volume correlated negatively with PTSD (p = 0.01) and depressive symptoms (p = 0.04). Vermal volume correlated negatively with PTSD symptoms (p < 0.01), early traumatic life events (p < 0.01), depressive symptoms (p = 0.04) and anxiety (p = 0.01).

CONCLUSION

The cerebellum is involved in emotion modulation, and our results suggest that cerebellar volumetric reduction is associated with mood, anxiety and PTSD symptoms. Early traumatic life experiences are related to vermal volume reduction and may be a risk factor for future PTSD development.

Potential cognitive endophenotypes in multigenerational families: segregating ADHD from a genetic isolate

Endophenotypes are neurobiological markers cosegregating and associated with illness. These biomarkers represent a promising strategy to dissect ADHD biological causes. This study was aimed at contrasting the genetics of neuropsychological tasks for intelligence, attention, memory, visual-motor skills, and executive function in children from multigenerational and extended pedigrees that cluster ADHD in a genetic isolate. In a sample of 288 children and adolescents, 194 (67.4%) ADHD affected and 94 (32.6%) unaffected, a battery of neuropsychological tests was utilized to assess the association between genetic transmission and the ADHD phenotype. We found significant differences between affected and unaffected children in the WISC block design, PIQ and FSIQ, continuous vigilance, and visual-motor skills, and these variables exhibited a significant heritability. Given the association between these neuropsychological variables and ADHD, and also the high genetic component underlying their transmission in the studied pedigrees, we suggest that these variables be considered as potential cognitive endophenotypes suitable as quantitative trait loci (QTLs) in future studies of linkage and association.

Paternal postpartum mood: bipolar episodes?

OBJECTIVE: We describe the prevalence of depressive and bipolar spectrum episodes in fathers in antenatal and postnatal periods, as well as at 12 months after childbirth. METHOD: A longitudinal follow-up study was conducted with a representative sample of 739 fathers whose children were born between April 2007 and May 2008 in maternity wards in the city of Pelotas, southern Brazil. Paternal psychopathology was measured with the Mini Neuropsychiatric Interview (MINI) across three time points: between 28 and 34 weeks of pregnancy (T1), 30 to 60 days postpartum (T2), and 12 months after childbirth (T3). RESULTS: The prevalence of depressive episodes was 5.0% at T1, 4.5% at T2, and 4.3% at T3. Mixed episodes were present in 3%, 1.7%, and 0.9% of subjects, respectively, and accounted for 61.1% of the cases of depression in the antenatal period, 37.5% in postpartum, and 21.4% at 12 months. Depressive and manic/hypomanic episodes were significantly associated during pregnancy and in postpartum, but not at 12 months after childbirth. CONCLUSION: Bipolar episodes were common in men with depressive symptoms during their partner's pregnancy in the postpartum period and, to a lesser extent, 12 months after childbirth. Therefore, this population should be carefully investigated for manic and hypomanic symptoms.

Somatização na América Latina: uma revisão sobre a classificação de transtornos somatoformes, síndromes funcionais e sintomas sem explicação médica

OBJETIVO: Os sintomas sem explicação médica são frequentes e estão associados a sofrimento mental em vários contextos. Estudos prévios apontam que as populações latino-americanas são propensas à somatização. Diante da reformulação da Classificação Internacional de Doenças para sua 11ª edição, as particularidades dos nativos desta região do mundo devem ser levadas em consideração. O objetivo deste estudo é prover informações sobre somatização na população latino-americana para a tomada de decisões quanto às categorias diagnósticas ligadas a sintomas sem explicação médica na Classificação Internacional de Doenças-11ª edição. MÉTODO: Revisão extensa da produção de 1995 a 2011 sobre somatização em populações de origem latino-americana. RESULTADOS: A análise dos 106 estudos incluídos nesta revisão foi dividida em 15 categorias: revisões sistemáticas, revisões conceituais, prevalências, atenção primária, depressão e ansiedade, fatores de risco, violência, quadros orgânicos, relacionamento com profissionais e o sistema de saúde, etnia, síndromes ligadas à cultura, síndrome da fadiga crônica, fibromialgia, transtorno dismórfico corporal, e conversão e dissociação. CONCLUSÃO: Os estudos latino-americanos confirmam a dificuldade na definição categorial de quadros com sintomas sem explicação médica. O suposto "traço somatizador" das culturas latinas pode estar associado mais à expressão cultural e linguística do que a um caráter de natureza étnica, e tais particularidades devem estar na agenda na nova classificação destes fenômenos na Classificação Internacional de Doenças-11ª edição.

A contribuição dos estudos transculturais dos países latino-americanos e caribenhos para a revisão da CID-10: resultados preliminares

OBJETIVO: Esta revisão visa identificar as evidências dos estudos de países da América Latina e do Caribe para a inclusão das síndromes transculturais na versão da Classificação Internacional de Doenças para sua 11ª Edição. MÉTODO: Os estudos foram identificados nas bases do Medline, LILACS e EMBASE, no período de 1992 a 2008, e classificados segundo o tipo de estudo, tipo de transtorno, país e número de publicações por ano. RESULTADOS: Foram selecionadas e classificadas 163 publicações: 33 no Medline, 90 no EMBASE e 40 no LILACS. A percentagem das síndromes transculturais ("culture bound-syndrome") correspondeu a 9% no Medline, 12% no EMBASE e 2,5% no LILACS. Dos 15 estudos sobre síndromes transculturais, dois eram sobre "nervios e ataque de nervios", dois sobre "susto", quatro sobre a relação entre crenças religiosas, "feitiçaria", transe e apresentação dos transtornos mentais, um sobre proposta de uma nova categoria diagnóstica, três artigos teóricos e três sobre psicopatoplastia dos transtornos mentais. CONCLUSÃO: A escassez de estudos sobre síndromes transculturais pode ter ocorrido pela dificuldade em rastrear os estudos por problema de indexação das publicações, falta de interesse em publicar tais estudos em periódicos indexados e a dificuldade de acesso às publicações. Dentre os estudos identificados, não há uma evidência clara que aponte quais modificações são necessárias nas classificações diagnósticas atuais.

Comparison of the Composite International Diagnostic interview (CIDI-Auto) with clinical diagnosis in a suicidal population

The objective was to examine agreement between routine clinician diagnoses of DSM-IV Anxiety, Depressive, Substance-Use disorders with diagnoses generated by CIDI-Auto Version 2.1, administered by trained interviewers. Subjects were 329 deliberate self poisoning patients at a tertiary referral center in Australia. Tests of agreement were: percentage agreement, sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios, and Cohen's kappa coefficients, for 1 month and 12 month CIDI diagnoses. Agreement was poor (kappa <0.40) for Anxiety, Depressive and Substance-Use disorders. Since diagnosis largely determines subsequent treatment, these findings did not support the use of the less expensive CIDI-Auto procedure to replace clinical diagnosis by experienced clinicians for this group of patients exhibiting suicidal behavior.

Psychometric and discriminative properties of the Teen Addiction Severity Index (Brazilian Portuguese version)

In this study we evaluated the internal consistency of the Brazilian Portuguese version of Teen Addiction Severity Index (T-ASI) and validated its "substance use" area. Evaluating 100 psychoactive substance abusers/dependent adolescents (SUD) and 108 adolescents without such diagnosis (NON-SUD), we found good correlations between the classification by the Composite International Diagnostic Interview (CIDI, used as "gold standard") and the severity (r = 0.73) and composite (r = 0.72) scores of the T-ASI. The area under the ROC curve was 0.88, showing a satisfactory correct classification rate. The internal consistency, evaluated by Cronbach's alpha coefficients, was considered good regarding the substance use (0.89), legal (0.81), and psychiatric (0.80) areas of the T-ASI. The Brazilian Portuguese version of T-ASI presented good internal consistency and a valid substance use area. A comparison between the groups regarding the answers to each question in all the areas was conducted in order to identify which questions in the T-ASI discriminate SUD from NON-SUD adolescents, to have a basis for the proposal of a shorter version of the instrument.

Violence and post-traumatic stress disorder in Sao Paulo and Rio de Janeiro, Brazil: the protocol for an epidemiological and genetic survey

BACKGROUND

violence is a public health major concern, and it is associated with post-traumatic stress disorder and other psychiatric outcomes. Brazil is one of the most violent countries in the world, and has an extreme social inequality. Research on the association between violence and mental health may support public health policy and thus reduce the burden of disease attributable to violence. The main objectives of this project were: to study the association between violence and mental disorders in the Brazilian population; to estimate the prevalence rates of exposure to violence, post-traumatic stress disorder, common metal disorder, and alcohol hazardous use and dependence: and to identify contextual and individual factors, including genetic factors, associated with the outcomes.

METHODS/DESIGN

one phase cross-sectional survey carried out in Sao Paulo and Rio de Janeiro, Brazil. A multistage probability to size sampling scheme was performed in order to select the participants (3000 and 1500 respectively). The cities were stratified according to homicide rates, and in Sao Paulo the three most violent strata were oversampled. The measurements included exposure to traumatic events, psychiatric diagnoses (CIDI 2.1), contextual (homicide rates and social indicators), and individual factors, such as demographics, social capital, resilience, help seeking behaviours. The interviews were carried between June/2007 February/2008, by a team of lay interviewers. The statistical analyses will be weight-adjusted in order to take account of the design effects. Standardization will be used in order to compare the results between the two centres. Whole genome association analysis will be performed on the 1 million SNP (single nucleotide polymorphism) arrays, and additional association analysis will be performed on additional phenotypes. The Ethical Committee of the Federal University of Sao Paulo approved the study, and participants who matched diagnostic criteria have been offered a referral to outpatient clinics at the Federal University of Sao Paulo and Federal University of Rio de Janeiro.

Prevalence of mental disorder and associated factors in civilian Guatemalans with disabilities caused by the internal armed conflict

BACKGROUND

The 34-year-long, Guatemalan war left at least 1,841 persons disabled in the country. The aim of this study was to describe the prevalence of mental disorders in individuals who acquired their disability as a result of the war, and to identify probable risk factors.

METHOD

A cross-sectional study was conducted of a group of 99 civilians with a disability in Guatemala. Participants were selected from four civilian organizations serving disabled persons in the municipality of Nebaj, Quiche. The diagnostic instrument was the computerized version of the Composite International Diagnostic Instrument 2.1 (CIDI 2.1). Data were collected from 2002 to 2004.

RESULTS

Of the 99 disabled persons who completed the interview, 44 had some type of lifetime psychiatric disorder. Post-traumatic stress disorder (PTSD) was the most prevalent, with 34.34% (34 cases), followed by dysthymia, with 10.10% (10 cases), and depression, with 6.06% (6 cases).

CONCLUSION

The traumatic events experienced during the conflict caused long-term psychological sequelae in people who were disabled as a result of the war. Increased exposure to traumatic events, being married, physical disability, illiteracy and advanced age were identified as probable risk factors for mental disorders .

Nosological profile and prevalence of common mental disorders of patients seen at the Family Health Program (FHP) units in Petrópolis, Rio de Janeiro

OBJECTIVES: This study aims to detect the prevalence of common mental disorders among patients seen by doctors at family health program units in Petrópolis-RJ, and to establish their nosological profile. METHOD: The population of the study included all 18 to 65-year-old patient who attended any family health program units included in the study during a 30-day period, between August and December 2002 (n = 714). The prevalence of common mental disorders was assessed using the General Health Questionnaire, 12 item version. In order to establish the nosological profile, the Composite International Diagnostic Interview was administered to all common mental disorders positive patients who accepted to return (n = 215). RESULTS: At the cut-off point of 2/3 the common mental disorders prevalence was 56% and for 4/5, it was 33%. The most frequent nosological categories found among common mental disorders positive patients were depression and anxiety categories along with posttraumatic stress disorder, somatoform pain disorder and dissociative disorders. There was a high frequency of comorbidity, especially between anxiety, depression, somatoform and dissociative disorders. CONCLUSIONS: The common mental disorders prevalence and the nosological profile found in FHP were similar to those of other primary care studies in Brazil, but some disorders (posttraumatic stress disorder, somatoform pain disorder and dissociative disorders) that had not been previously studied in this context were also very frequent. The high common mental disorders prevalence found reinforces the urgent need for systematic inclusion of this level of care in mental health assistance planning.
