Gender-based violence and mental disorders in female college students

Purpose

To assess the association between gender-based violence and DSM-IV Axis I disorders in female college students.

Methods

A stratified random sample of 1,043 college women (average age 22.2?years) participated in the study. We collected sociodemographic, socioeconomic and academic information as well as information on the participants’ experience of gender-based violence victimization. The presence of mental disorders during the 12?months preceding the study was assessed by clinically trained interviewers applying the Structured Clinical Interview for DSM-IV Axis I disorders-Clinician Version (SCID-CV).

Results

15.2% of the participants reported lifetime gender-based violence victimization. Almost two-thirds of the victims had suffered some Axis I disorder during the past year, a significantly larger proportion than among non-victims (OR?=?3.72; 95% CI 2.61–5.30). Mood disorders and anxiety disorders were both significantly more common among victims than non-victims (OR?=?4.26; 95% CI 2.81–6.46 and OR?=?1.97; 95% CI 1.20–3.24, respectively). The most prevalent individual disorder among victims was major depressive disorder (26.41%). Among victims of purely psychological violence, the overall rate of Axis I disorder was similar to the rate among other victims (67 and 61%, respectively).

Conclusions

Among female university students, the experience of physical or psychological gender-based violence is associated with mental disorder. These findings suggest the need for treatment and prevention interventions designed specifically for this population.     

What characteristics of primary anxiety disorders predict subsequent major depressive disorder?

OBJECTIVE: The goal of this study was to examine the associations between specific anxiety disorders and the risk of major depressive disorder and to explore the role of various clinical characteristics of anxiety disorders in these relationships using a prospective, longitudinal design. METHOD: The data are from a 4-year prospective, longitudinal community study, which included both baseline and follow-up survey data on 2548 adolescents and young adults aged 14 to 24 years at baseline. DSM-IV diagnoses were made using the Munich-Composite International Diagnostic Interview. RESULTS: The presence at baseline of any anxiety disorder (odds ratio [OR] = 2.2 [95% CI = 1.6 to 3.2]) and each of the anxiety disorders (specific phobia, OR = 1.9 [95% CI = 1.3 to 2.8]; social phobia, OR = 2.9 [95% CI = 1.7 to 4.8]; agoraphobia, OR = 3.1 [95% CI = 1.4 to 6.7]; panic disorder, OR = 3.4 [95% CI = 1.2 to 9.0]; generalized anxiety disorder, OR = 4.5 [95% CI = 1.9 to 10.3]) was associated with a significantly (p <.05) increased risk of first onset of major depressive disorder. These associations remained significant after we adjusted for mental disorders occurring prior to the onset of the anxiety disorder, with the exception of the panic disorder association. The following clinical characteristics of anxiety disorders were associated with a significantly (p <.05) increased risk of developing major depressive disorder: more than 1 anxiety disorder, severe impairment due to the anxiety disorder, and comorbid panic attacks. In the final model, which included all clinical characteristics, severe impairment remained the only clinical characteristic that was an independent predictor of the development of major depressive disorder (OR = 2.2 [95% CI = 1.0 to 4.4]). CONCLUSION: Our findings suggest that anxiety disorders are risk factors for the first onset of major depressive disorder. Although a number of clinical characteristics of anxiety disorders appear to play a role in the association between anxiety disorders and depression, severe impairment is the strongest predictor of major depressive disorder.     

Mental disorders and asthma in the community

OBJECTIVE: To determine the association between asthma and mental disorders among adults in the community. SETTING: Germany. PARTICIPANTS: Representative sample of the general population aged 18 to 65 years. MAIN OUTCOME MEASURES: Diagnoses of current (the past 4 weeks) and lifetime asthma were based on physician diagnosis; current and lifetime DSM-IV mental disorders were assessed using the Composite International Diagnostic Interview. RESULTS: Current severe asthma (the past 4 weeks) was associated with a significantly increased likelihood of any anxiety disorder (odds ratio [OR], 2.65; 95% confidence interval [CI], 1.35-5.18), specific phobia (OR, 4.78; 95% CI, 2.35-4.05), panic disorder (OR, 4.61; 95% CI, 1.09-9.4), and panic attacks (OR, 4.12; 95% CI, 1.32-12.8). Lifetime severe asthma was associated with the increased likelihood of any anxiety disorder (OR, 2.09; 1.3-3.36), panic disorder (OR, 2.61; 95% CI, 1.29-5.25), panic attacks (OR, 2.84; 95% CI, 1.66, 4.89), social phobia (OR, 3.28; 95% CI, 1.42, 7.59), specific phobia (OR, 2.93; 95% CI, 1.71-5.0), generalized anxiety disorder (OR, 5.51; 95% CI, 2.29-13.22), and bipolar disorder (OR, 5.64; 95% CI, 1.95-16.35). Current nonsevere asthma was associated with the increased likelihood of any affective disorder (OR, 2.42; 95% CI, 1.03-5.72); and lifetime nonsevere asthma was associated with increased odds of any anxiety disorder (OR, 1.51; 95% CI, 1.0-2.32), anxiety disorder not otherwise specified (OR, 2.08; 95% CI, 1.03-4.23), and any somatoform disorder (OR, 1.7; 95% CI, 1.14-2.53). CONCLUSIONS: To our knowledge, these findings are consistent with and extend the findings of previous reports by providing the first available information on the association between physician-diagnosed asthma and DSM-IV mental disorders in a representative population sample of adults. Our results suggest an association between asthma and a range of mental disorders. Longitudinal studies that can examine the sequence of onset and the role of genetic and environmental factors in the association between asthma and affective and anxiety disorders are needed next to further elucidate possible shared causative mechanisms.     

Associations between psychotic-like experiences and mental health status and other psychopathologies among Japanese early teens

Psychotic-like experiences (PLEs) are considered predictive of mental health problems later in life. However, little has been known about the mental health status and psychopathological distress in adolescents with PLEs in the general population. To investigate the associations between PLEs and mental health status or psychopathologies in a community sample of adolescents in a school-based cross-sectional fashion, PLEs were studied using a self-rating questionnaire in 5073 Japanese junior-high school students aged 12-15 years. Mental health status was evaluated using the 12-item General Health Questionnaire (GHQ-12). Psychopathologies, lifestyle, victimization, and interpersonal and help-seeking attitudes were also studied using a self-rating questionnaire. Fifteen percent of the students reported definitely having experienced at least one PLE. A dose-response relationship between the severity of PLEs and the prevalence of poor mental health status was observed. PLEs were also significantly associated with psychopathologies (strong anxiety in the classroom: OR = 1.4, 95% CI 1.2-1.6; suicidal ideation: OR = 2.1, 95% CI 1.8-2.4; self-harm behaviors: OR = 1.4, 95% CI 1.0-1.9; difficulty falling asleep due to hypersensitivity to environmental noise: OR = 1.7, 95% CI 1.4-2.0; difficulty concentrating due to hypersensitivity to environmental noise: OR = 1.5, 95% CI 1.3-1.8; physically assaulting others: OR = 1.3, 95% CI 1.0-1.5; bullying others, OR = 1.3, 95% CI 1.1-1.5; irritability when exchanging e-mails: OR = 1.3, 95% CI 1.0-1.6). Adolescents with PLEs in the community suffer from a wide range of psychopathological problems during crucial developmental periods [corrected]     

Mental disorders among English-speaking Mexican immigrants to the US compared to a national sample of Mexicans

Our understanding of the relationship between immigration and mental health can be advanced by comparing immigrants pre- and post-immigration with residents of the immigrants' home countries. DSM-IV anxiety and mood disorders were assessed using identical methods in representative samples of English-speaking Mexican immigrants to the US, a subsample of the US National Comorbidity Survey Replication (NCSR), and Mexicans, the Mexican National Comorbidity Survey (MNCS). Retrospective reports of age of onset of disorders and, in the immigrant sample, age of immigration were analyzed to study the associations of pre-existing mental disorders with immigration and of immigration with the subsequent onset and persistence of mental disorders. Pre-existing anxiety disorders predicted immigration (OR=3.0; 95% CI 1.2-7.4). Immigration predicted subsequent onset of anxiety (OR=1.9; 95% CI 0.9-3.9) and mood (OR=2.3; 95% CI 1.3-4.0) disorders and persistence of anxiety (OR=3.7 95% CI 1.2-11.2) disorders. The results are inconsistent with the "healthy immigrant" hypothesis (that mentally healthy people immigrate) and partly consistent with the "acculturation stress" hypothesis (i.e., that stresses of living in a foreign culture promote mental disorder). Replication and extension of these results in a larger bi-national sample using a single field staff are needed.     

Smoking increases the risk of panic: findings from a prospective community study

BACKGROUND: We examined prospectively determined bidirectional associations between smoking and panic and other anxiety disorders and their temporal ordering of onset in a representative community sample of adolescents and young adults. METHODS: Baseline and 4-year follow-up data were used from the Early Developmental Stages of Psychopathology Study, a prospective longitudinal study of adolescents and young adults in Munich, Germany. We assessed smoking (occasional and regular), nicotine dependence, panic attacks, panic disorder, other anxiety disorders, and other mental disorders using the Munich-Composite International Diagnostic Interview. RESULTS: At baseline, panic attacks and panic disorder were strongly associated with occasional and regular smoking and nicotine dependence (odds ratio [OR] range, 3.0-28.0). In the prospective analyses, we found increased risk for new onset of panic attacks with prior regular smoking (OR, 2.9; 95% confidence interval [CI], 1.0-8.4) and nicotine dependence (OR, 3.6; 95% CI, 1.2-10.5). Prior nicotine dependence increased also the risk for onset of panic disorder (OR, 3.3; 95% CI, 1.0-10.5), whereas preexisting panic was not associated with subsequent smoking or nicotine dependence. When using Cox regression with time-dependent covariates, prior nicotine dependence was confirmed to be related to subsequent panic attacks (hazard ratio, 2.7; 95% CI, 1.7-4.2), but not panic disorder (hazard ratio, 1.7; 95% CI, 0.7-3.9). Rather, we found indications that prior panic attacks/disorder might also have an effect on secondary development of nicotine dependence. CONCLUSIONS: In young adults, prospective analyses revealed a fairly unique and specific, unidirectional relationship between prior smoking and increased risk for subsequent panic attacks/disorder. However, we could not exclude the existence of a second, less frequent, reverse pathway of prior panic and secondary nicotine dependence.     

“Anxietas Tibiarum”

Abstract Background Symptoms of anxiety and depression in patients with restless legs syndrome (RLS) have been observed. However, it is unclear whether rates of threshold depression and anxiety disorders according to DSM-IV criteria in such patients are also elevated. Methods 238 RLS patients were assessed with a standardized diagnostic interview (Munich-Composite International Diagnostic Interview for DSM-IV) validated for subjects aged 18–65 years. Rates of anxiety and depressive disorders were compared between 130 RLS patients within this age range and 2265 community respondents from a nationally representative sample with somatic morbidity of other types. Results RLS patients revealed an increased risk of having 12-month anxiety and depressive disorders with particularly strong associations with panic disorder (OR=4.7; 95% CI=2.1–10.1), generalized anxiety disorder (OR=3.5; 95% CI= 1.7–7.1), and major depression (OR=2.6; 95% CI=1.5–4.4). In addition, lifetime rates of panic disorder and most depressive disorders as well as comorbid depression and anxiety disorders were considerably increased among RLS patients compared with controls. Conclusions The results suggest that RLS patients are at increased risk of having specific anxiety and depressive disorders. Causal attributions of patients suggest that a considerable proportion of the excess morbidity for depression and panic disorder might be due to RLS symptomatology.     

Early age of onset of mood,anxiety and alcohol use disorders is associated with sociodemographic characteristics and health outcomes in adults: results from a cross-sectional national survey

Purpose

This cross-sectional study investigated distribution, sociodemographic correlates, and health outcomes in early versus late age of onset (AOO) of mood, anxiety, and alcohol use disorders in Singapore.

Methods

The Composite International Diagnostic Interview established lifetime diagnoses of major depressive, bipolar, generalized anxiety, obsessive compulsive and alcohol use disorders in a representative sample of residents aged 18 years and over (n = 6126). The AOO of the individual and any mental disorders were classified into early and late onset using median values as cut-offs. Data included socio-demographic and health background, health utility score, and productivity losses. Multivariable logistic regression analysis was conducted to assess sociodemographic correlates of early versus late AOO of any mental disorder while linear regression analysis investigated the associations between AOO of individual disorders with health utility score and productivity loss.

Results

Respondents’ mean (SD) age was 45.6 (16.5) years, comprising 50.5% women and majority of Chinese ethnicity (75.8%). The median AOO for any of the five studied disorders was 21 years (IQR: 15–29). Lowest AOO was observed for obsessive compulsive disorder (Median: 14, IQR: 11–26). Those aged 35 years and over (versus 18–34) were less likely to have earlier AOO [35–49 years (OR: 0.287; 95% CI: 0.154–0.534); 50–64 years (OR:0.156; 95% CI: 0.068–0.361) and 65 and over (OR:0.112; 95% CI:0.027–0.461)], while Malay ethnicity (versus Chinese) (OR: 2.319; 95% CI: 1.384–3.885) and being never married (versus married) (OR: 2.731; 95% CI: 1.493–4.993) were more likely to have early AOO for any mental disorder. Sample with early (versus late) AOO had a lower health utility score (β =  − 0.06,95% CI: − 0.08 to − 0.03) and higher number of days cut down on the type of work (β = 1.61,95% CI: 0.12–3.10) in those with any mental disorders.

Conclusion

This study showed that half of the adults with mood, anxiety or alcohol use disorders in Singapore experienced their illness onset by 21 years of age. Early AOO is associated with sociodemographic background and poor health outcomes. Prevention, early detection, and interventions to improve health outcomes in mental disorders should consider the sociodemographic profile and age at first onset of symptoms in the population.

     

Predictors of Mental Health Treatment Seeking and Engagement in a Community Mental Health Center

Disparities in behavioral health treatment outcomes are multifactorial, but treatment engagement and dropout from treatment often contribute to unequal mental health outcomes in individuals with serious mental illnesses. Alcohol and other substance use disorders have been associated with poor treatment adherence and premature discontinuation of treatment, but few studies have examined these factors in a predominantly African American sample of individuals with serious mental illnesses. This study examined predictors of mental health treatment engagement and dropout in a sample of 90 African American individuals presenting for treatment at a community mental health treatment facility in Atlanta, Georgia. Having an alcohol use disorder was associated with being less likely to attend mental health follow up (OR 0.32, 95% CI 0.12–0.88). Among African American individuals with alcohol use disorders, specific, targeted interventions may be necessary to help reach individuals that are at extremely high risk of poor health and poor adherence to treatment.     

The specific burden of comorbid anxiety disorders and of substance use disorders in bipolar I disorder

OBJECTIVES: Uncertainty exists regarding whether comorbid substance use disorders (SUDs) in bipolar I disorder are more prevalent among persons with versus without comorbid anxiety disorders. Moreover, the independent contribution of these comorbidities to the burden of bipolar disorder (BD) is unclear. METHODS: The 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions was used to identify respondents with lifetime BD (n = 1,411). Illness severity was compared across four groups based on the presence of lifetime anxiety disorders, lifetime SUDs, neither, or both. Variables included lifetime prevalence of mixed mania, prolonged mood episodes, BD-related health service utilization, and forensic history, 12-month prevalence of mania and depression, and current general mental health functioning. Diagnoses were generated using the National Institute on Alcohol Abuse and Alcoholism Alcohol Use Disorder and Associated Disabilities Interview Schedule, DSM-IV Version. Analyses were computed separately for males and females. RESULTS: For females only, the lifetime prevalence of SUDs was significantly greater among those with lifetime anxiety disorders [odds ratio (OR) = 1.41, 95% confidence interval (CI) = 1.08-1.86]; this was not found among males (OR = 1.15, 95% CI = 0.79-1.68). In multiple logistic regression analyses among both males and females, anxiety disorders were significantly associated with mixed episodes, prolonged depressive episodes, 12-month prevalence of depression, BD-related health service utilization, and poorer current mental health functioning. SUDs were significantly associated with mixed episodes among females, 12-month prevalence of depression among males, and with forensic history among both males and females. CONCLUSIONS: Whereas comorbid anxiety disorders appear to confer increased liability towards poor mental health functioning and greater BD-related health service utilization, comorbid SUDs are associated with positive forensic history. Early identification and treatment of these comorbid conditions are of paramount importance. Further representative prospective studies are needed.     

A population study of the association between sleep disturbance and suicidal behaviour in people with mental illness

Limited representative research has considered the relationship between sleep disturbance and suicidal behaviour among people with mental illness. We investigated the relationship between sleep disturbance and suicidal behaviour across Part II interview of the National Comorbidity Survey Replication (NCSR). The associations between sleep disturbance and suicidal behaviour (thoughts, plans and attempts) were investigated using logistic and multinomial logistic regressions and stratified across six mental disorder groups (depression, anxiety, substance use disorders (SUD), eating disorders (ED), bipolar disorders (BD) and early life disorders). From 5701 participants (mean age 43.4 years 58% women), people with any mental disorder experiencing sleep disturbance were at increased odds of suicidal thoughts (odds ratio (OR): 2.5; 95% CI: 1.7, 3.6) and suicidal plans and attempts (OR: 5.7; 95% CI: 2.7, 11.9) adjusting for age, sex and income. People with BD (OR: 8.9; 95 CI: 2.1, 38.1), early life disorders (OR 6.98, 95% ci 2.48, 19.67), depression (OR 1.88, 95% CI 1.14, 3.11), anxiety (OR 1.90, 95% CI 1.28, 2.85) and SUD (2.60, 95% CI 1.23, 5.49) but not ED, were at increased odds of suicidal thoughts in the presence of sleep disturbance. Adjusting for anti-depressant intake attenuated the effect sizes by up to 20% but the associations remained significant. In conclusion, sleep disturbance is a potential risk factor for suicidal behaviours in people with mental illness. Monitoring and management of sleep disturbance in clinical practice might be an important strategy to mitigate suicidal behaviours in people with mental illness.     

Association between obesity and psychiatric disorders in the US adult population

BACKGROUND: Epidemiologic data suggest an association between obesity and depression, but findings vary across studies and suggest a stronger relationship in women than men. OBJECTIVE: To evaluate the relationship between obesity and a range of mood, anxiety, and substance use disorders in the US general population. DESIGN: Cross-sectional epidemiologic survey. SETTING: Nationally representative sample of US adults. PARTICIPANTS: A total of 9125 respondents who provided complete data on psychiatric disorder, height, and weight. Response rate was 70.9%. MAIN OUTCOME MEASURES: Participants completed an in-person interview, including assessment of a range of mental disorders (assessed using the World Health Organization Composite International Diagnostic Interview) and height and weight (by self-report). RESULTS: Obesity (defined as body mass index [calculated as weight in kilograms divided by the square of height in meters] of > or =30) was associated with significant increases in lifetime diagnosis of major depression (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.09-1.35), bipolar disorder (OR, 1.47; 95% CI, 1.12-1.93), and panic disorder or agoraphobia (OR, 1.27; 95% CI, 1.01-1.60). Obesity was associated with significantly lower lifetime risk of substance use disorder (OR, 0.78; 95% CI, 0.65-0.93). Subgroup analyses found no difference in these associations between men and women, but the association between obesity and mood disorder was strongest in non-Hispanic whites (OR, 1.38; 95% CI, 1.20-1.59) and college graduates (OR, 1.44; 95% CI, 1.14-1.81). CONCLUSIONS: Obesity is associated with an approximately 25% increase in odds of mood and anxiety disorders and an approximately 25% decrease in odds of substance use disorders. Variation across demographic groups suggests that social or cultural factors may moderate or mediate the association between obesity and mood disorder.     

Correlates of youth suicide attempters in Australian community and clinical samples

OBJECTIVE: This study (i) explores differences between a clinical sample of deliberate self-poisoning (DSP) patients and a community sample who reported previous attempted suicide (AS); and (ii) examines correlates of suicidal behaviour in these groups compared with a community control group (CC) with no suicidal behaviour. METHOD: The study design was: case-case, case-control and cross-sectional population studies. A clinical sample of DSP (n = 51), a community sample of AS (n = 31) and a community sample with no suicidal behaviour (n = 842) were used, all aged 18-24 years. The DSP and AS groups were compared on several variables and two logistic regression models were developed for risk of (i) DSP and (ii) AS compared to community controls. RESULTS: The adjusted odds ratios for DSP were: female gender (OR = 5.7, CI = 1.7-19.4), anxiety (OR = 7.4, CI = 2.2-25.1), affective (OR = 23.0, CI = 6.9-76.5), or substance-use disorder (OR = 19.2, CI = 5.6-65.4) and greater mental health related disability (OR = 0.5, CI = 0.3-0.7 for 1 SD decrease). For AS the results were: anxiety (OR = 9.4, CI = 1.7-52.8) or substance-use disorder (OR = 3.0, CI = 1.1-8.7) and greater mental health disability (OR = 0.5, CI = 0.4-0.7). Affective disorder was close to significant for the AS group (OR = 4.0, CI = 0.9-17.1). CONCLUSIONS: Correlates of DSP/AS were usually more powerful in the clinical group, but showed a similar pattern of psychiatric disorder and disability factors in both groups, supporting a continuum of risk factors across these groups. Interventions based on modifiable risk factors could target the same factors for public health, primary care or hospital populations: anxiety, depression and substance use disorders and mental health related disability.     

Is sexual orientation related to mental health problems and suicidality in young people?

BACKGROUND: This study examines the extent to which gay, lesbian, and bisexual young people are at increased risk of psychiatric disorder and suicidal behaviors using data gathered on a New Zealand birth cohort studied to age 21 years. METHODS: Data were gathered during the course of the Christchurch Health and Development Study, a 21-year longitudinal study of a birth cohort of 1265 children born in Christchurch, New Zealand. At 21 years of age, 1007 sample members were questioned about their sexual orientation and relationships with same-sex partners since the age of 16 years. Twenty-eight subjects (2.8%) were classified as being of gay, lesbian, or bisexual sexual orientation. Over the period from age 14 to 21 years, data were gathered on a range of psychiatric disorders that included major depression, generalized anxiety disorder, conduct disorder, and substance use disorders. Data were also gathered on suicidal ideation and suicide attempts. RESULTS: Gay, lesbian, and bisexual young people were at increased risks of major depression (odds ratio [OR], 4.0; 95% confidence interval [CI], 1.8-9.3), generalized anxiety disorder (OR, 2.8; 95% CI, 1.2-6.5), conduct disorder (OR, 3.8; 95% CI, 1.7-8.7), nicotine dependence (OR, 5.0; 95%, CI, 2.3-10.9), other substance abuse and/or dependence (OR, 1.9; 95% CI, 0.9-4.2), multiple disorders (OR, 5.9; 95% CI, 2.4-14.8), suicidal ideation (OR, 5.4; 95% CI, 2.4-12.2), and suicide attempts (OR, 6.2; 95% CI, 2.7-14.3). CONCLUSIONS: Findings support recent evidence suggesting that gay, lesbian, and bisexual young people are at increased risk of mental health problems, with these associations being particularly evident for measures of suicidal behavior and multiple disorder.     

The relationship between neighborhood-level socioeconomic characteristics and individual mental disorders in five cities in Latin America: multilevel models from the World Mental Health Surveys

Purpose

Our understanding of community-level predictors of individual mental disorders in large urban areas of lower income countries is limited. In particular, the proportion of migrant, unemployed, and poorly educated residents in neighborhoods of these urban areas may characterize group contexts and shape residents’ health.

Methods

Cross-sectional household interviews of 7251 adults were completed across 83 neighborhoods of Buenos Aires, Argentina; Medellín, Colombia; São Paulo, Brazil; Lima, Peru; and Mexico City, Mexico as part of the World Mental Health Survey Initiative. Past-year internalizing and externalizing mental disorders were assessed, and multilevel models were used.

Results

Living in neighborhoods with either an above-average or below-average proportion of migrants and highly educated residents was associated with lower odds of any internalizing disorder (for proportion migrants: OR 0.75, 95% CI 0.62–0.91 for the bottom tertile and OR 0.79, 95% CI 0.67–0.94 for the top tertile compared to the middle tertile; for proportion highly educated: OR 0.76, 95% CI 0.64–0.90 for the bottom tertile and OR 0.58, 95% CI 0.37–0.90 for the top tertile compared to the middle tertile). Living in neighborhoods with an above-average proportion of unemployed individuals was associated with higher odds of having any internalizing disorder (OR 1.49, 95% CI 1.14–1.95 for the top tertile compared to the middle tertile). The proportion of highly educated residents was associated with lower odds of externalizing disorder (OR 0.54, 95% CI 0.31–0.93 for the top tertile compared to the middle tertile).

Conclusions

The associations of neighborhood-level migration, unemployment, and education with individual-level odds of mental disorders highlight the importance of community context for understanding the burden of mental disorders among residents of rapidly urbanizing global settings.

     

Meta-analysis of self-reported substance use compared with laboratory substance assay in general adult mental health settings

An accurate assessment of substance use is necessary to make a correct psychiatric diagnosis and to provide appropriate treatment. This study uses meta-analysis to establish the strength of the association between self-reported substance use and the results of laboratory substance assay including the testing for specific substances and screening for any substance use in psychiatric hospitals and in community mental health settings. A systematic search for published studies was supplemented by additional data required for meta-analysis provided by several researchers in this field. Using random-effects meta-analysis, we calculated the pooled estimate of the odds ratio of a positive substance assay in patients reporting use or non-use of substances and estimated the sensitivity, specificity, positive predictive value and negative predictive value. Twenty-six studies met the inclusion criteria. Very strong associations were found between self-reported use and positive tests for cannabis [N = 11 studies, odds ratio (OR) = 22.3; 95% confidence interval (CI) = 10.1-49.1], amphetamines (N = 8, OR = 26.6; 95% CI = 7.9-88.9), cocaine (N = 8, OR = 39.7; 95% CI = 16.2-97.2) and opiates (N = 7, OR = 83.5; 95% CI = 26.7-260.7). Strong associations were found between self-reported use of any substance and positive substance screening (N = 15, OR = 7.2, 95% CI = 3.6-14.1) and tests for alcohol use (N = 5, OR = 8.5; 95% CI = 2.5-28.4). Screening for any substance use had a sensitivity of 61% and a specificity of 66%. Testing for individual substances was specific but lacked sensitivity. Screening has the potential to detect clinically relevant substances that would not be reported by the patient, whereas testing for a specific substance has little advantage over self-report. The sensitivity of the substance assay might be improved by obtaining a sample at the earliest opportunity. Consideration should be given to the increased use of substance screening in general adult mental health settings because it could improve the accuracy of psychiatric diagnosis and increase the likelihood of patients receiving treatment for substance use disorders.     

Parental major depression and the risk of depression and other mental disorders in offspring: a prospective-longitudinal community study

BACKGROUND: This article examines associations between DSM-IV depressive disorders, their natural course, other psychopathology, and parental major depression in a community sample of adolescents and young adults. METHODS: Baseline and 4-year follow-up data were used from the Early Developmental Stages of Psychopathology Study, a prospective-longitudinal community study of adolescents and young adults. Results are based on 2427 subjects who completed the follow-up and for whom diagnostic information for both parents was available. DSM-IV mental disorders in respondents were assessed using the Munich-Composite International Diagnostic Interview. Information on depression in parents was collected as family history information from the respondents and from diagnostic interviews with parents of the younger cohort. RESULTS: Offspring with 1 (odds ratio [OR], 2.7; 95% confidence interval [CI], 2.1-3.5) or 2 affected parents (OR, 3.0; 95% CI, 2.2-4.1) had an increased risk for depression. They also had a higher risk for substance use (1 parent affected: OR, 1.4; 95% CI, 1.1-1.7; both parents affected: OR, 1.4; 95% CI, 1.0-1.8) and anxiety disorders (1 parent affected: OR, 1.6; 95% CI, 1.3-1.9; both parents affected: OR, 2.1; 95% CI, 1.6-2.8). There were no differences whether mother or father was affected. Parental depression was associated with an earlier onset and a more malignant course (severity, impairment, recurrence) of depressive disorders in offspring. CONCLUSIONS: Major depression in parents increases the overall risk in offspring for onset of depressive and other mental disorders and influences patterns of the natural course of depression in the early stages of manifestation.     

High prevalence of mental disorders and comorbidity in the Geneva Gay Men’s Health Study

Background Several large surveys have suggested high prevalence of psychiatric disorders among gay men and other men who have sex with men. Methods In 2002, a comprehensive health survey was conducted among 571 gay men in Geneva, Switzerland, using probability-based time-space sampling. The Composite International Diagnostic Interview Short-Form (CIDI-SF) was used to assess 12-month prevalence of major depression, specific phobia, social phobia, alcohol dependence, and drug dependence. Results Nearly half (43.7%, 95% CI=39.0–48.4) of the sample fulfilled the criteria for at least one of the five DSM-IV disorders: 19.2% had major depression, 21.9% had specific and/or social phobia, and 16.7% had an alcohol and/or drug dependence disorder in the past 12 months. Over one quarter of the cases were comorbid with another kind of disorder, and 35.7% of cases consulted a health care professional in the past 12 months for mental health. Like cases, screen-positives for mood and/or anxiety disorders (24.7%) also reported significantly greater disability and lower quality of life. Conclusions Nearly two-thirds of this community sample of gay men was affected by psychiatric morbidity with new evidence for comorbidity, subthreshold disorders, and low levels of awareness of psychiatric disorders and their treatment. This population needs to be a priority in psychiatric epidemiology and mental public health.
