ABSTRACT
BACKGROUND: people suffering from substance use disorders (SUD) often die by suicide, so that the prevention of suicide attempts (SA) remains a top priority in this population. SA recurrence is common and is associated with suicide death, but this phenotype has been overlooked in SUD populations. Thus, we aimed at identifying the risk factors of SA recurrence in SUD, controlling for both gender and levels of exposure to addictive substances, including tobacco. METHODS: we consecutively recruited 433 treatment-seeking outpatients with either opiate or cocaine use disorder and assessed their lifetime history of addictive and suicidal symptoms by standardized questionnaires. They were reliably classified as never, single or recurrent (≥â¯2) suicide attempters, whose characteristics were identified by multinomial regression, stratified by gender; and compared to our previous work on serious SA in order to identify common or different risk profiles. RESULTS: 86/140 (61%) suicide attempters reported recurrence. The mean number of SA was 3.1. Recurrence was independently associated with psychiatric hospitalization in both genders, with nicotine dependence in men and with sedative use disorders in women. LIMITATIONS: psychiatric diagnoses were derived from the current medication regimen. CONCLUSION: specific and possibly avoidable/treatable risk factors for the recurrence of SA in SUD have been identified for the first time, opening new avenues for research and prevention in this high-risk population. Apart from nicotine dependence, these risk factors were very similar to those of serious SA. Although this comparison is indirect for now, it suggests a common liability towards suicidal behavior.

OBJECTIVES: Religiosity is often associated with better health outcomes. The aim of the study was to examine associations between psychotic experiences (PEs) and religiosity in a large, cross-national sample. METHODS: A total of 25 542 adult respondents across 18 countries from the WHO World Mental Health Surveys were assessed for PEs, religious affiliation and indices of religiosity, DSM-IV mental disorders and general medical conditions. Logistic regression models were used to estimate the association between PEs and religiosity with various adjustments. RESULTS: Of 25 542 included respondents, 85.6% (SE = 0.3) (n = 21 860) respondents reported having a religious affiliation. Overall, there was no association between religious affiliation status and PEs. Within the subgroup having a religious affiliation, four of five indices of religiosity were significantly associated with increased odds of PEs (odds ratios ranged from 1.3 to 1.9). The findings persisted after adjustments for mental disorders and/or general medical conditions, as well as religious denomination type. There was a significant association between increased religiosity and reporting more types of PEs. CONCLUSIONS: Among individuals with religious affiliations, those who reported more religiosity on four of five indices had increased odds of PEs. Focussed and more qualitative research will be required to unravel the interrelationship between religiosity and PEs.

BACKGROUND: Research on post-traumatic stress disorder (PTSD) course finds a substantial proportion of cases remit within 6 months, a majority within 2 years, and a substantial minority persists for many years. Results are inconsistent about pre-trauma predictors. METHODS: The WHO World Mental Health surveys assessed lifetime DSM-IV PTSD presence-course after one randomly-selected trauma, allowing retrospective estimates of PTSD duration. Prior traumas, childhood adversities (CAs), and other lifetime DSM-IV mental disorders were examined as predictors using discrete-time person-month survival analysis among the 1575 respondents with lifetime PTSD. RESULTS: 20%, 27%, and 50% of cases recovered within 3, 6, and 24 months and 77% within 10 years (the longest duration allowing stable estimates). Time-related recall bias was found largely for recoveries after 24 months. Recovery was weakly related to most trauma types other than very low [odds-ratio (OR) 0.2-0.3] early-recovery (within 24 months) associated with purposefully injuring/torturing/killing and witnessing atrocities and very low later-recovery (25+ months) associated with being kidnapped. The significant ORs for prior traumas, CAs, and mental disorders were generally inconsistent between early- and later-recovery models. Cross-validated versions of final models nonetheless discriminated significantly between the 50% of respondents with highest and lowest predicted probabilities of both early-recovery (66-55% v. 43%) and later-recovery (75-68% v. 39%). CONCLUSIONS: We found PTSD recovery trajectories similar to those in previous studies. The weak associations of pre-trauma factors with recovery, also consistent with previous studies, presumably are due to stronger influences of post-trauma factors.

AIMS: A substantial proportion of persons with mental disorders seek treatment from complementary and alternative medicine (CAM) professionals. However, data on how CAM contacts vary across countries, mental disorders and their severity, and health care settings is largely lacking. The aim was therefore to investigate the prevalence of contacts with CAM providers in a large cross-national sample of persons with 12-month mental disorders. METHODS: In the World Mental Health Surveys, the Composite International Diagnostic Interview was administered to determine the presence of past 12 month mental disorders in 138 801 participants aged 18-100 derived from representative general population samples. Participants were recruited between 2001 and 2012. Rates of self-reported CAM contacts for each of the 28 surveys across 25 countries and 12 mental disorder groups were calculated for all persons with past 12-month mental disorders. Mental disorders were grouped into mood disorders, anxiety disorders or behavioural disorders, and further divided by severity levels. Satisfaction with conventional care was also compared with CAM contact satisfaction. RESULTS: An estimated 3.6% (standard error 0.2%) of persons with a past 12-month mental disorder reported a CAM contact, which was two times higher in high-income countries (4.6%; standard error 0.3%) than in low- and middle-income countries (2.3%; standard error 0.2%). CAM contacts were largely comparable for different disorder types, but particularly high in persons receiving conventional care (8.6-17.8%). CAM contacts increased with increasing mental disorder severity. Among persons receiving specialist mental health care, CAM contacts were reported by 14.0% for severe mood disorders, 16.2% for severe anxiety disorders and 22.5% for severe behavioural disorders. Satisfaction with care was comparable with respect to CAM contacts (78.3%) and conventional care (75.6%) in persons that received both. CONCLUSIONS: CAM contacts are common in persons with severe mental disorders, in high-income countries, and in persons receiving conventional care. Our findings support the notion of CAM as largely complementary but are in contrast to suggestions that this concerns person with only mild, transient complaints. There was no indication that persons were less satisfied by CAM visits than by receiving conventional care. We encourage health care professionals in conventional settings to openly discuss the care patients are receiving, whether conventional or not, and their reasons for doing so.

BACKGROUND: Suicide is a major public health concern and suicide attempts (SA) are frequent and burdensome in people suffering from substance use disorders (SUDs). In particular, serious SAs are a preoccupying form of attempt, which remain largely overlooked in these populations, especially regarding basic risk factors such as gender, addictive comorbidity and substance use patterns. Thus, we undertook a gender-specific approach to identify the risk factors for serious SAs in outpatients with multiple SUDs. MATERIAL AND METHODS: 433 Treatment-seeking outpatients were consecutively recruited in specialized care centers and reliably classified as serious, non-serious and non-suicide attempters. We also characterized lifetime exposure to SUDs, including tobacco smoking, with standardized instruments. Current medication, including psychotropic treatments were collected, which informed psychiatric diagnoses. Multinomial regression identified independent factors specifically associated with serious SAs in each gender, separately. RESULTS: 32% Participants (N=139, 47% Women and 27% Men) reported lifetime SA. There were 82 serious attempters (59% of attempters), without significant gender difference. Sedative dependence was an independent risk factor for serious SA compared to non-SA in Women and compared to non-serious SA in Men, respectively. Other risk factors included later onset of daily tobacco smoking in Men and history of psychiatric hospitalizations in Women, whose serious SA risk was conversely lower when reporting opiate use disorder or mood disorder, probably because of treatment issues. CONCLUSIONS: Despite several study limitations, we identified subgroups for a better-tailored prevention of serious SAs among individuals with SUDs, notably highlighting the need to better prevent and treat sedative dependence.

BACKGROUND: Although specific phobia is highly prevalent, associated with impairment, and an important risk factor for the development of other mental disorders, cross-national epidemiological data are scarce, especially from low- and middle-income countries. This paper presents epidemiological data from 22 low-, lower-middle-, upper-middle- and high-income countries. METHOD: Data came from 25 representative population-based surveys conducted in 22 countries (2001-2011) as part of the World Health Organization World Mental Health Surveys initiative (n = 124 902). The presence of specific phobia as defined by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition was evaluated using the World Health Organization Composite International Diagnostic Interview. RESULTS: The cross-national lifetime and 12-month prevalence rates of specific phobia were, respectively, 7.4% and 5.5%, being higher in females (9.8 and 7.7%) than in males (4.9% and 3.3%) and higher in high- and higher-middle-income countries than in low-/lower-middle-income countries. The median age of onset was young (8 years). Of the 12-month patients, 18.7% reported severe role impairment (13.3-21.9% across income groups) and 23.1% reported any treatment (9.6-30.1% across income groups). Lifetime co-morbidity was observed in 60.5% of those with lifetime specific phobia, with the onset of specific phobia preceding the other disorder in most cases (72.6%). Interestingly, rates of impairment, treatment use and co-morbidity increased with the number of fear subtypes. CONCLUSIONS: Specific phobia is common and associated with impairment in a considerable percentage of cases. Importantly, specific phobia often precedes the onset of other mental disorders, making it a possible early-life indicator of psychopathology vulnerability.

BACKGROUND: Although there is robust evidence linking childhood adversities (CAs) and an increased risk for psychotic experiences (PEs), little is known about whether these associations vary across the life-course and whether mental disorders that emerge prior to PEs explain these associations. METHOD: We assessed CAs, PEs and DSM-IV mental disorders in 23 998 adults in the WHO World Mental Health Surveys. Discrete-time survival analysis was used to investigate the associations between CAs and PEs, and the influence of mental disorders on these associations using multivariate logistic models. RESULTS: Exposure to CAs was common, and those who experienced any CAs had increased odds of later PEs [odds ratio (OR) 2.3, 95% confidence interval (CI) 1.9-2.6]. CAs reflecting maladaptive family functioning (MFF), including abuse, neglect, and parent maladjustment, exhibited the strongest associations with PE onset in all life-course stages. Sexual abuse exhibited a strong association with PE onset during childhood (OR 8.5, 95% CI 3.6-20.2), whereas Other CA types were associated with PE onset in adolescence. Associations of other CAs with PEs disappeared in adolescence after adjustment for prior-onset mental disorders. The population attributable risk proportion (PARP) for PEs associated with all CAs was 31% (24% for MFF). CONCLUSIONS: Exposure to CAs is associated with PE onset throughout the life-course, although sexual abuse is most strongly associated with childhood-onset PEs. The presence of mental disorders prior to the onset of PEs does not fully explain these associations. The large PARPs suggest that preventing CAs could lead to a meaningful reduction in PEs in the population.

Benzodiazepines should be prescribed on a short-term basis, but a significant proportion of patients (%) use them for more than 6 months, constituting a serious public health issue. Indeed, few strategies are effective in helping patients to discontinue long-term benzodiazepine treatments. The aim of this study was to assess the feasibility and the impact of a program including cognitive behavioural therapy, psychoeducation, and balneotherapy in a spa resort to facilitate long-term discontinuation of benzodiazepines. We conducted a prospective multicentre cohort study. Patients with long-term benzodiazepine use were recruited with the aim of anxiolytic withdrawal by means of a psychoeducational program and daily balneotherapy during 3 weeks. The primary efficacy outcome measure was benzodiazepine use 6 months after the program, compared to use at baseline. A total of 70 subjects were enrolled. At 6 months, overall benzodiazepine intake had decreased by 75.3%, with 41.4% of patients completely stopping benzodiazepine use. The results also suggest a significantly greater improvement in anxiety and depression symptoms among patients who discontinued benzodiazepines compared to patients who only reduced their use. Our findings suggest that balneotherapy in association with a psychoeducative program is efficient in subjects with benzodiazepine addiction.
ABSTRACT
BACKGROUND: Considerable research has documented that exposure to traumatic events has negative effects on physical and mental health. Much less research has examined the predictors of traumatic event exposure. Increased understanding of risk factors for exposure to traumatic events could be of considerable value in targeting preventive interventions and anticipating service needs. METHOD: General population surveys in 24 countries with a combined sample of 68 894 adult respondents across six continents assessed exposure to 29 traumatic event types. Differences in prevalence were examined with cross-tabulations. Exploratory factor analysis was conducted to determine whether traumatic event types clustered into interpretable factors. Survival analysis was carried out to examine associations of sociodemographic characteristics and prior traumatic events with subsequent exposure. RESULTS: Over 70% of respondents reported a traumatic event; 30.5% were exposed to four or more. Five types - witnessing death or serious injury, the unexpected death of a loved one, being mugged, being in a life-threatening automobile accident, and experiencing a life-threatening illness or injury - accounted for over half of all exposures. Exposure varied by country, sociodemographics and history of prior traumatic events. Being married was the most consistent protective factor. Exposure to interpersonal violence had the strongest associations with subsequent traumatic events. CONCLUSIONS: Given the near ubiquity of exposure, limited resources may best be dedicated to those that are more likely to be further exposed such as victims of interpersonal violence. Identifying mechanisms that account for the associations of prior interpersonal violence with subsequent trauma is critical to develop interventions to prevent revictimization.

INTRODUCTION: The burden of health problems, including mental disorders, can be assessed in several ways such as through healthcare costs or loss of productivity. Their impact on daily activities as a whole has received much less attention, especially in France. Therefore, we undertook the analysis of the French general population data from the World Mental Health (WMH) surveys promoted by the World Health Organization (WHO) assessing the number of days out of role due to common mental and physical disorders. METHODS: Face-to-face interviews were carried out with 2894 respondents (45.9% pooled response rate). Presence of ten chronic physical disorders and nine mental disorders was assessed for each respondent along with information about the number of days in the past month each respondent reported being totally unable to work or carry out their other normal daily activities because of problems with either physical or mental health. Multiple regression analysis was used to estimate associations of specific conditions and comorbidities with days out of role, after controlling for basic socio-demographics. RESULTS: One thousand four hundred and thirty-six subjects reporting at least one core-symptom of a mental disorder underwent the whole assessment. The mean annual number of days out of role was high among those with at least one mental disorder (24.2±8.3). The population attributable risk proportion (PARP), i.e. the proportion of days out of role that would have been avoided if the considered disorder had remitted, was also estimated. Mental disorders as a whole accounted for 49.5% of the PARP. DISCUSSION: French data on days out of role from the WHO WMH surveys showed the high burden of mental illness in the general population. These results may have been underestimated, taking into account that subjects who were hospitalized at the time of recruitment, whose disorders might also account for a high proportion of days out of role, could not be assessed with our design. CONCLUSION: Common health conditions, especially mental disorders, make up a large proportion of the number of days out of role. Such data should be considered to design more efficient public health strategies.

INTRODUCTION: Cytomegalovirus (CMV) is a member of the herpesviridae family that has a limbic and temporal gray matter tropism. It is usually latent in humans but has been associated with schizophrenia, bipolar disorder and cognitive deficits in some populations. Hippocampal decreased volume and dysfunction play a critical role in these cognitive deficits. We hypothesized that CMV seropositivity and serointensity would be associated with hippocampal volume and cognitive functioning in patients with schizophrenia or bipolar disorder. METHODS: 102 healthy controls, 118 patients with bipolar disorder and 69 patients with schizophrenia performed the California Verbal Learning Test (CVLT) and had blood samples drawn to assess CMV IgG levels. A subgroup of 52 healthy controls, 31 patients with bipolar disorder and 27 patients with schizophrenia underwent T1 MRI for hippocampal volumetry. We analyzed the association between CMV serointensity and seropositivity with hippocampal volume. We also explored the correlation between CMV serointensity and seropositivity and CVLT scores. RESULTS: In both patient groups but not in controls, higher CMV serointensity was significantly associated with smaller right hippocampal volume. Further, in the group of patients with schizophrenia but not bipolar disorder, CMV serointensity was negatively correlated with CVLT scores. CONCLUSION: CMV IgG titers are associated with decreased hippocampal volume and poorer episodic verbal memory in patients with schizophrenia or bipolar disorder. The mechanism of this association warrants further exploration.

BACKGROUND: In this global study we sought to estimate the degree to which a family member might feel embarrassed when a close relative is suffering from an alcohol, drug, or mental health condition (ADMC) versus a general medical condition (GMC). To date, most studies have considered embarrassment and stigma in society and internalized by the afflicted individual but have not assessed family embarrassment in a large-scale study. METHOD: In 16 sites of the World Mental Health Surveys (WMHS), standardized assessments were completed including items on family embarrassment. Site matching was used to constrain local socially shared determinants of stigma-related feelings, enabling a conditional logistic regression model that estimates the embarrassment close relatives may hold in relation to family members affected by an ADMC, a GMC, or both conditions. RESULTS: There was a statistically robust association such that subgroups with an ADMC-affected relative were more likely to feel embarrassed compared to subgroups with a relative affected by a GMC (p<0.001), even with covariate adjustments for age and sex. CONCLUSIONS: . The pattern of evidence from this research is consistent with conceptual models for interventions that target individual- and family-level stigma-related feelings of embarrassment as possible obstacles to effective early intervention and treatment for an ADMC. Macro-level interventions are under way but micro-level interventions may also be required among family members, along with care for each person with an ADMC.

BACKGROUND: Current trends in population aging affect both recipients and providers of informal family caregiving, as the pool of family caregivers is shrinking while demand is increasing. Epidemiological research has not yet examined the implications of these trends for burdens experienced by aging family caregivers. Method Cross-sectional community surveys in 20 countries asked 13 892 respondents aged 50+ years about the objective (time, financial) and subjective (distress, embarrassment) burdens they experience in providing care to first-degree relatives with 12 broadly defined serious physical and mental conditions. Differential burden was examined by country income category, kinship status and type of condition. RESULTS: Among the 26.9-42.5% respondents in high-, upper-middle-, and low-/lower-middle-income countries reporting serious relative health conditions, 35.7-42.5% reported burden. Of those, 25.2-29.0% spent time and 13.5-19.4% money, while 24.4-30.6% felt distress and 6.4-21.7% embarrassment. Mean caregiving hours per week in those giving any time were 16.6-23.6 (169.9-205.8 h/week per 100 people aged 50+ years). Burden in low-/lower-middle-income countries was 2- to 3-fold higher than in higher-income countries, with any financial burden averaging 14.3% of median family income in high-, 17.7% in upper-middle-, and 39.8% in low-/lower-middle-income countries. Higher burden was reported by women than men and for conditions of spouses and children than parents or siblings. CONCLUSIONS: Uncompensated family caregiving is an important societal asset that offsets rising formal healthcare costs. However, the substantial burdens experienced by aging caregivers across multiple family health conditions and geographic regions threaten the continued integrity of their caregiving capacity. Initiatives supporting older family caregivers are consequently needed, especially in low-/lower-middle-income countries.

BACKGROUND AND OBJECTIVE: Suicide is a public health problem worldwide. The objective of this study is to analyse the prevalence and risk factors of suicide related outcomes (ideation, plan and attempt) using data from the ESEMeD-France project. SUBJECTS AND METHOD: This is a face-to-face household survey carried out in a probability representative sample of the adult general population of France. A total of 6796 subjects were interviewed using the Composite International Diagnostic Interview (CIDI) developed framework of the World Mental Health Survey Initiative. Based on evidence that reports of such potentially embarrassing behaviour are higher in self-administered than interviewer-administered surveys, these questions were printed in a self-administered booklet and referred to by letter. RESULTS: Lifetime prevalence of suicide ideation, plan and attempts were 12.4, 4.4 and 3.4% respectively. Risk of suicide-related outcomes was significantly higher among women and younger cohorts. Having a mental disorder was associated with an increased risk, especially in the case of psychiatric comorbidity. Mental disorders that are associated with an increase in suicidal attempts are anxiety disorders (except social phobia), major depressive episodes, oppositional defiant disorders, and attention deficit hyperactivity disorders. The suicidal risk notably increases in conjunction with multiple mental disorders. In this study, employment and marital status do not appear to be a risk factor for suicidal behaviour. CONCLUSIONS: The prevalence of suicide-related outcomes is high when compared with other countries. Results identified groups with higher risk (women, young, subjects with a mental disorder and having a plan) in which suicide prevention could to be targeted. The results of this study suggest that to improve suicide prevention strategies it is necessary to perform an in-depth clinical evaluation of suicidal ideas and projects, and identify precisely psychiatric comorbidity to allow a more efficient treatment.

BACKGROUND: The cannabis withdrawal syndrome occurs after cannabis cessation in more than 50% of dependent smokers. But although opioid-dependent patients are more frequently cannabis users and cannabis-dependent than the general population, the frequency and phenomenology of cannabis withdrawal symptoms in this specific population is unknown. Our hypothesis was that cannabis-dependent patients with current opioid dependence would experience the same withdrawal syndrome after cannabis cessation. OBJECTIVE: To describe cannabis withdrawal symptoms in cannabis-only dependent patients and in cannabis-dependent patients with current opioid dependence. METHODS: Using retrospective interviews, we evaluated the number and duration of six cannabis withdrawal symptoms in two groups: 56 cannabis-dependent patients without and 43 cannabis dependent patients with current opioid dependence. Cannabis and opioid dependence diagnoses were defined with DSM IV criteria using the MINI structured interview. RESULTS: The two groups were not different in terms of age of onset of cannabis use, and number of cannabis joints smoked at the time of the cannabis cessation attempt. The frequency of a cannabis withdrawal syndrome (defined as at least two different symptoms) did not differ in the two groups (65%). Neither was the proportion of subjects with the following symptoms: appetite or weight loss (30.8%), irritability (45.1%), anxiety (56%), aggression (36.3%) and restlessness (45.1%). Patients with cannabis dependence and current opioid dependence were more likely to report sleep disturbances (79.1 vs. 53.6%, chi(2)=6.91, P=0.007). The median duration of this cannabis withdrawal syndrome was 20 days post-cessation. CONCLUSION: This is, to our knowledge, the first study describing cannabis withdrawal syndrome in cannabis-dependent patients with current opioid dependence. These patients experience a cannabis withdrawal syndrome as often as cannabis-only dependent subjects, but describe more frequently sleep disturbances. This high rate of sleep disturbances may cause relapse to cannabis use.

BACKGROUND: Suicidality risk-factors between countries with similar economic and religious background have been rarely compared, especially within genders. METHODS: Lifetime prevalence of suicide ideation, plans, and attempts in the ESEMeD surveys were stratified on four separate groups: French women, Spanish women, French men, and Spanish men. Outcome odds-ratios (OR) were modelled within each group using logistic regression including demographic characteristics, lifetime mood/anxiety disorders, parental bonding, marital status, and health service-use. RESULTS: Lifetime prevalence of suicide attempts was 3.4% in France (1.1% men, 5.4% women) and 1.5% in Spain (1.2% men, 1.7% women), with a significantly greater gender difference in France (p=0.001). Regarding risk-factors, French women reported suicide attempt more commonly with authoritarian mothers (OR=1.51; 95%CI=1.04-2.18), unlike Spanish women (OR=0.77; 95%CI=0.51-1.15) (p<0.001). Spanish men showed more than eight-times higher odds of suicide attempt with overprotecting mothers than French men (p=0.03). General practitioner-(GP)-use was significantly protective of suicide attempt among Spanish women (OR=0.08; 95%CI=0.02-0.35) with no effect in French women (OR=1.03; 95%CI=0.54-2.00) (p=0.01). No significant differences in the effect of marital status, any lifetime antidepressant use, mental disorders, or religiosity on suicide attempt were observed between France and Spain within gender-stratum. LIMITATIONS: Parental bonding is retrospective and potentially influenced by mental state. Response rate was considerably lower in France than in Spain. CONCLUSIONS: Suicidality risk-factors play different roles across genders between France and Spain. Parental bonding dimensions may be interpreted differently according to country, underlining cultural importance. As recommended by WHO, mental health decisions must involve GPs in conjunction with psychiatrists or psychologists.

Cocaine addiction is a chronic disease marked by relapses, co-morbidities and the importance of psychosocial consequences. The etiology of cocaine addiction is complex and involves three types of factors: environmental factors, factors linked to the specific effects of cocaine and genetic factors. The latter could explain 40-60% of the risk for developing an addiction. Several studies have looked for a link between cocaine addiction and the genes of the dopaminergic system: the genes DRD2, COMT, SLC6A3 (coding for the dopamine transporter DAT) and DBH (coding for the dopamine beta hydroxylase) but unfortunately very few well established results. Pharmacogenetic approach could be an interesting opportunity for the future. The gene DBH has particularly been linked with the psychotic effects caused by cocaine. This so-called cocaine-induced psychosis (CIP) or cocaine-induced paranoia may influence the development of cocaine addiction. Indeed, these psychotic symptoms during cocaine exposure could cause an aversive effect limiting the development of an addiction. Several functional alterations caused by different mutations of the genes involved in dopaminergic transmission (principally-1021C>T of the gene DBH, but also Val158Met of the gene COMT, TaqI A of the gene DRD2 and VNTR 9 repeat of the DAT) could result in a cocaine-induced psychosis prone phenotype. We are hypothesising that the appearance of CIP during the first contact with cocaine is associated with a lower risk of developing cocaine addiction. This protective effect could be associated with the presence of one or more polymorphisms associated with CIP. A pharmacogenetic approach studying combination of polymorphism could isolate a sub-group of patients at risk for CIPs but more favorably protected from developing an addiction. This theory could enable a better understanding of the protective factors against cocaine addiction and offer new therapeutic or preventive targets in vulnerable sub-groups exposed to cocaine.

BACKGROUND: The prevalence of obsessive-compulsive symptom dimensions and their sociodemographic and psychopathological correlates at the population level are unknown. METHOD: Obsessive-compulsive symptom dimensions and mental disorders were assessed with the Composite International Diagnostic Interview 3.0 in a random subsample (n=2804) of individuals participating in a cross-sectional survey of the adult general population of six European countries. RESULTS: The lifetime prevalence of any obsessive-compulsive symptom dimension was 13%. Harm/Checking was the most prevalent dimension (8%) followed by Somatic obsessions (5%) and Symmetry/Ordering (3%). Females were more likely to have symptoms in Contamination/Cleaning (OR=3, 95%CI=1.06-8.51) and Somatic obsessions (OR=1.88, 95%CI=1.05-3.37). All symptom dimensions were associated with an increased risk of most mental (but not physical) disorders. There were some differences in prevalence between countries. LIMITATIONS: The interference associated with each symptom dimension could not be assessed. Few direct data are available on the validity of the CIDI to assess obsessive-compulsive symptom dimensions. CONCLUSIONS: Obsessive-compulsive symptom dimensions are relatively frequent in the general population. Their sociodemographic and psychopathological correlates may be slightly different in clinical and community samples. They are associated with an increased risk of most mental disorders.

CONTEXT: In the 1990s, cannabis consumption in France increased considerably. So, in 10 years, the number of adolescents reporting regular cannabis use (10 or more times during the last 12 months) tripled. In 2004, an official program to address problems related to cannabis addiction was implemented. As part of this program, specific outpatient settings for cannabis use disorders were created. OBJECTIVE: We present the sociodemographic characteristics, the prevalence of cannabis, alcohol and others psychoactive substances and the prevalence of mental disorders in 90 cannabis users seen at an outpatient specific setting for cannabis use disorders in the Lariboisière hospital (a university hospital in Paris). MEASURES: Twelve months prevalence of substance abuse and dependence, psychiatric diagnoses based on the DSM-IV and the Mini-International Neuropsychiatric Interview (MINI) results are described. RESULTS: The study population had the following characteristics: 67% male, mean age 27.5 (S.D.=8.4) years and 59% single or divorced. Approximately, two-thirds of the users (67%) were students or currently working and 32% were unemployed. Twenty-two percent of the cannabis users received unemployment, welfare or disability benefits and 11% declared no source of revenue. Most of the users (63%) decided on their own to seek care at the setting. Seventy-three percent of the subjects had seen a psychologist or a psychiatrist in the past, with or without relation to cannabis use. By far, most of the users were cannabis dependent (82%) and 9% cannabis abusers in the last 12 months according to DSM-IV criteria prior to their visit. Seven percent of the cannabis users had alcohol dependence and 7% were abusers. The 12 months prevalence of cocaine or ecstasy dependence was 2% and the prevalence of benzodiazepines, heroin or stimulants dependence 1%. The main substances used over lifetime were tobacco (99%); alcohol (96%); cocaine (41%); benzodiazepines and hypnotics (41%); ecstasy (40%) and heroin (23%). Four percent of cannabis users had a history of intravenous drug use. The main consumption mode of cannabis in France is the blunt. About three-quarters of the consumption is in the form of resin (hashish) and one-quarter as marijuana (grass). The average consumption of cannabis in the last six months was equivalent to 5.8 blunts per day (S.D.=4.4) and 12 g per week (S.D.=10.5), and the average monthly cost was 159 euro (S.D.=133) (234 USD, S.D.=196). The prevalence of psychiatric disorders according to DSM-IV criteria in the sample is high. A current mood disorder was present in 48% and an anxiety disorder in 55% of the cannabis users in the last 12 months. The prevalence of affective disorders in the last 12 months was major depressive disorder (38%), dysthymia (19%), hypomania (3%) and mania (1%). The prevalence of anxiety disorders in the last 12 months was social phobia (29%); generalised anxiety disorder (17%); panic disorder with or without agoraphobia (16%); obsessive compulsive disorder (12%); agoraphobia without panic disorder (9%) and post-traumatic stress disorder (5%). The prevalence of schizophrenia was 4%. The prevalence of bulimia was 4% and no anorexia. Women are more likely to report an affective disorder (64% versus 41%; p=0.04) or a post-traumatic stress disorder (17% versus 0%; p<0.001) in the last 12 months. The prevalence of family history for psychiatric disorders was 52% and for addiction, 59%. CONCLUSIONS: The cannabis users seen in our specific setting are a fairly homogeneous group and for the most part addicted to cannabis only, but with very high rates of dependence. Indeed, other than tobacco dependence, 80% of the users were only dependent on, or abused on cannabis in the last 12 months. In comparison with the cohort of French cannabis users (n=4202) seen at specific outpatient settings for marijuana users in 2005, cannabis users seen in Lariboisière Hospital are older, the percentage of females is greater, they are more dependent on marijuana and have a high prevalence of affective and anxiety disorders.
