Comparison Between Musculoskeletal Pain and Gender-Specific, Non-gendered Job-Exposure Matrix and Self-reported Exposures in CONSTANCES.

PURPOSE: Musculoskeletal disorders (MSDs) are common worldwide and gender differences exist in terms of prevalence and disability. MSDs are a leading cause of sick leave and physical work exposures. To assess the association between physical exposures assessed by the gender-specific CONSTANCES Job-Exposure Matrix (JEM) and musculoskeletal pain in six areas: neck pain, shoulder pain, elbow/arm pain, hand/wrist pain, low back pain, knee/leg pain; and to compare the results with those obtained using the non-gendered CONSTANCES JEM and with individual self-report exposures. METHODS: We included 48,736 male and 63,326 female workers from the CONSTANCES cohort (France). The association between 27 physical exposures and musculoskeletal self-reported pain in six body areas was assessed using logistic regression. We conducted the analysis with three types of exposures: (1) individual self-reported exposures; (2) gender-specific CONSTANCES JEM; (3) non-gendered CONSTANCES JEM, and adjusted for age and Body Mass Index (BMI). Analyses were stratified by gender. RESULTS: The associations to the gender-specific and non-gendered JEM were similar. The odds ratios using individual self-reported exposures were comparable to the JEM-based associations, with the exceptions of the exposures 'change tasks', 'rest eyes' and 'reach behind'. In some comparisons, there were differences in the direction and/or significance of effects between genders (regardless of whether the JEM used was gender-specific or not). CONCLUSION: The gender-specific and non-gendered JEMs gave similar results, hence, developing physical work exposures JEMs that are gender-specific may not be essential. However, when predicting musculoskeletal pain, it seems relevant to stratify the analysis by gender.

Development and evaluation of the gender-specific CONSTANCES job exposure matrix for physical risk factors in France.

OBJECTIVES: This study aimed to construct and evaluate a gender-specific job exposure matrix (JEM) for 27 physical work exposures, based on self-report. METHODS: We constructed a JEM using questionnaire data on current physical exposures from 29 381 male and 35 900 female asymptomatic workers aged 18-69 years in the French CONSTANCES cohort study. We excluded workers with musculoskeletal pain to reduce potential reporting bias. We grouped 27 self-reported physical exposures using the French national job codes and stratified by gender. We compared individual and group-based exposures using the performance indicators Cohen's kappa (κ), sensitivity, specificity, and area under the receiver operating curve (AUC). RESULTS: JEM validation showed fair-to-moderate agreement (κ 0.21-0.60) for most physical exposures for both genders except for 'reach behind' (poor), 'bend neck' (poor), 'finger pinch' (poor), standing' (good), 'use computer screen' (good), and 'use keyboard or scanner' (good). We found the highest AUC for 'standing' (men 0.85/ women 0.87), 'kneel/squat' (men 0.80/women 0.81), 'use computer screen' (men/women 0.81), and 'use keyboard or scanner' (men 0.82/ women 0.84). The AUC was <0.60 for only three exposures: 'bend neck' (men 0.58/women 0.57), 'finger pinch' (men 0.56/ women 0.55), and 'reach behind' (men 0.54/ women 0.51). CONCLUSION: The constructed JEM validation measures were comparable for men and women for all exposures. Further research will examine the predictive ability of this gender-specific JEM for musculoskeletal disorders and the relevance of gender-stratification in this process, knowing accuracy of each exposure.

Comparing physical work exposures between men and women: findings from 65 281 workers in France.

OBJECTIVES: Musculoskeletal disorders (MSDs) are a leading cause of disability and sick leave among workers. Although MSDs are associated with physical exposures, there are gender differences in the prevalence and related disability. This study aimed to compare self-reported physical work exposures by gender for people within the same occupational group. METHODS: We used cross-sectional data from 65 281 asymptomatic workers aged 18-69 years from the CONSTANCES cohort study (France). We compared 27 physical exposures between men and women in the same occupational groups ('Profession et Categorie Sociale' group) using Mann-Whitney U tests. RESULTS: Men and women performing the same job often reported different levels of exposure. 38 of 365 occupational groups had a gender difference in reported exposure for 10 or more of 27 physical exposures, with men reporting higher exposures in 79% of these jobs. Women reported higher exposures in nursing and other healthcare professions. The probability that a random man had an exposure value higher than a random woman varied widely, from 8% to 92%, and was highly dependent on occupational groups and the specific exposure. CONCLUSIONS: Men and women working in the same jobs reported different physical exposures for some jobs and some exposures. Further research should further define and explore these reported differences to improve prevention and research.

Comparison of Machine Learning Methods in the Study of Cancer Survivors' Return to Work: An Example of Breast Cancer Survivors with Work-Related Factors in the CONSTANCES Cohort.

PURPOSE: Machine learning (ML) methods showed a higher accuracy in identifying individuals without cancer who were unable to return to work (RTW) compared to the classical methods (e.g. logistic regression models). We therefore aim to discuss the value of these methods in relation to RTW for cancer survivors. METHODS: Breast cancer (BC) survivors who were working at diagnosis within the CONSTANCES cohort were included in the study. RTW was assessed five years after the BC diagnosis (early retirement was considered as non-RTW). Age and occupation at diagnosis, and physical occupational job exposures assessed using the Job Exposure Matrix, JEM-CONSTANCES, were evaluated as predictors of RTW five years after BC diagnosis. The following four ML methods were used: (i) k-nearest neighbors; (ii) random forest; (iii) neural network; and (iv) elastic net. RESULTS: The training sample included 683 BC survivors (RTW: 85.7%), and the test sample 171 (RTW: 85.4%). The elastic net method had the best results despite low sensitivity (accuracy = 76.6%; sensitivity = 31.7%; specificity = 90.8%), and the random forest model was the most accurate (= 79.5%) but also the least sensitive (= 14.3%). CONCLUSION: This study takes a first step towards opening up new possibilities for identifying the occupational determinants of cancer survivors' RTW. Further work, including a larger sample size, and more predictor variables, is now needed.

Association between COVID-19 infection and work exposure assessed by the Mat-O-Covid job exposure matrix in the CONSTANCES cohort.

OBJECTIVES: The COVID-19 pandemic has brought to light a new occupational health threat. We aimed to evaluate the association between COVID-19 infection and work exposure to SARS-CoV-2 assessed by a job-exposure matrix (JEM), in a large population cohort. We also estimated the population-attributable fraction among exposed subjects. METHODS: We used the SAPRIS-SERO sample of the CONSTANCES cohort, limited to subjects actively working, and with a job code available and a questionnaire on extra work activities. The following outcomes were assessed: COVID-19 diagnosis was made by a physician; a seropositivity to the ELISA-S test ('serology strict') and ELISA-S test intermediate with positive ELISA-NP or a positive neutralising antibodies SN ('serology large'). Job exposure was assessed using Mat-O-Covid, an expert-based JEM with an Index used as a continuous variable and a threshold at 13/1000. RESULTS: The sample included 18 999 subjects with 389 different jobs, 47.7% were men with a mean age of 46.2 years (±9.2 years). The Mat-O-Covid index taken as a continuous variable or with a threshold greater than 13/1000 was associated with all the outcomes in bivariable and multivariable logistic models. ORs were between 1.30 and 1.58, and proportion of COVID-19 attributable to work among exposed participants was between 20% and 40%. DISCUSSION: Using the Mat-O-Covid JEM applied to a large population, we found a significant association between work exposure to SARS-CoV-2 and COVID-19 infection, though the estimation of attributable fraction among exposed people remained low to moderate. Further studies during other exposed periods and with other methods are necessary.

Mat-O-Covid: Validation of a SARS-CoV-2 Job Exposure Matrix (JEM) Using Data from a National Compensation System for Occupational COVID-19.

Background. We aimed to assess the validity of the Mat-O-Covid Job Exposure Matrix (JEM) on SARS-CoV-2 using compensation data from the French National Health Insurance compensation system for occupational-related COVID-19. Methods. Deidentified compensation data for occupational COVID-19 in France were obtained between August 2020 and August 2021. The case acceptance was considered as the reference. Mat-O-Covid is an expert-based French JEM on workplace exposure to SARS-CoV-2. Bi- and multivariable models were used to study the association between the exposure assessed by Mat-O-Covid and the reference, as well as the area under the curve (AUC), sensitivity, specificity, predictive values, and likelihood ratios. Results. In the 1140 cases included, there was a close association between the Mat-O-Covid index and the reference (p < 0.0001). The overall predictivity was good, with an AUC of 0.78 and an optimal threshold at 13 per thousand. Using Youden's J statistic resulted in 0.67 sensitivity and 0.87 specificity. Both positive and negative likelihood ratios were significant: 4.9 [2.4−6.4] and 0.4 [0.3−0.4], respectively. Discussion. It was possible to assess Mat-O-Covid's validity using data from the national compensation system for occupational COVID-19. Though further studies are needed, Mat-O-Covid exposure assessment appears to be accurate enough to be used in research.

Procode: A Machine-Learning Tool to Support (Re-)coding of Free-Texts of Occupations and Industries.

Procode is a free of charge web-tool that allows automatic coding of occupational data (free-texts) by implementing Complement Naïve Bayes (CNB) as a machine-learning technique. The paper describes the algorithm, performance evaluation, and future goals regarding the tool's development. Almost 30 000 free-texts with manually assigned classification codes of French classification of occupations (PCS) and French classification of activities (NAF) were used to train CNB. A 5-fold cross-validation found that Procode predicts correct classification codes in 57-81 and 63-83% cases for PCS and NAF, respectively. Procode also integrates recoding between two classifications. In the first version of Procode, this operation, however, is only a simple search function of recoding links in existing crosswalks. Future focus of the project will be collection of the data to support automatic coding to other classification and to establish a more advanced method for recoding.

Health behaviors: is there any distinction for teachers? A cross-sectional nationwide study.

BACKGROUND: Health behaviors, as important modifiable determinants of health, are consistently targeted by prevention messages. Teachers, as educators and role models, may play a key-role in bringing such messages to children and adolescents. It is not clear which areas of prevention could be improved in collaboration with teachers to promote healthy behaviors at the population level through health education in schools. METHODS: to evaluate teacher's health awareness, we compared their health/risk behaviors to those of non-teachers, taking into account demographic and socioeconomic factors that could confound crude differences. We used data from the 2010 Health Barometer, a cross-sectional nationally-representative French survey conducted by telephone among 27,653 persons aged 15-85. Adjusting sequentially for potential confounders, we compared six indicators of lifestyle and risky conducts (at-risk drinking, current smoking, cannabis use, gambling, corpulence, sleep duration) between teachers (n = 725) and two comparison groups: other occupations (n = 12,483) on the one hand, and other intermediate and managerial/professional occupations (n = 6,026) on the other. RESULTS: In the fully-adjusted models, teachers were less likely than other occupations to smoke, to have used cannabis in the last 12 months, to gamble regularly and to be overweight or obese. When restricting the comparison group to other occupations belonging to the same socio-professional category, differences were attenuated, but remain highly significant for tobacco, cannabis and gambling. No significant differences were observed between teachers and non-teachers regarding alcohol use and sleep duration, once important confounders had been adjusted for. CONCLUSIONS: Our results suggest that teachers behave on the whole more healthily than other adults with a similar demographic and socioeconomic profile. The absence of a teacher distinction toward at-risk drinking needs to be examined in more detail.

Respondents in an epidemiologic survey had fewer psychotropic prescriptions than nonrespondents: an insight into health-related selection bias using routine health insurance data.

OBJECTIVES: Using register-based insurance data, we aimed to evaluate health-related differences between respondents and nonrespondents in a mailed epidemiologic survey, with a particular focus on mental health. STUDY DESIGN AND SETTING: In 2005, 19,406 adults covered by the national education system health insurance plan were sent a general health questionnaire including a significant part devoted to mental health. Of them, 52% responded. Using multivariable logistic regression models, we compared participants and nonparticipants on various sociodemographic characteristics, morbidity variables, and health care utilization indicators derived from the routine health insurance databases, regardless of response status. Mental health was appraised through the reimbursement of psychiatric services and the volume of psychotropic prescriptions received in 2004-05. RESULTS: In addition to traditional sociodemographic covariates of participation, we observed that respondents used more medical services than nonrespondents (visits to general practitioners, dentists, and specialists other than psychiatrists) but essentially for somatic disorders, as they also were prescribed significantly fewer psychotropic drugs. CONCLUSION: Response bias may impact estimation quality even in apparently sociodemographically homogeneous populations. Our results confirmed that persons with mental complaints are less likely to respond to a survey focused on their troubles and illustrate the risk of underestimation of psychiatric disease in population-based surveys.

Lifetime risk of suicidal behaviors and communication to a health professional about suicidal ideation. Results from a large survey of the French adult population.

BACKGROUND: There is presently a lack of information on the role of healthcare in suicidal ideation in adults. AIMS: To assess the frequencies, patterns, and factors associated with the communication of suicidal ideation toward a health professional. METHODS: Participants stem from a French cross-sectional survey of 22,133 randomly selected adults. Lifetime suicidal behaviors and 12-month mental disorder patterns were assessed using the short form of the Composite International Diagnostic Interview. Participants with suicidal ideation were asked whether they had talked about it and, if they had, to whom. RESULTS: Around 20% of people with suicidal ideation had talked about this distress to a health professional. It was more frequent for people with more severe suicidal behaviors (plan or a prior attempt), among women, those aged 30 or more, those suffering from major depressive episode, panic disorder, or drug use disorder. Above all, it was more frequent among those who had also talked to friends or relatives. CONCLUSIONS: Prevention strategies that encourage suicidal persons to seek help for their distress, whoever that is, may be the more important strategies to develop.

Mental health care and out-of-pocket expenditures in Europe: results from the ESEMeD project.

BACKGROUND: Most published data on out-of-pocket spending on mental health originate from the United States, where insurance payments for mental health have traditionally been much less generous than benefits for other health care services. Given the difference in the structure of health care funding in Europe, it is clearly important to obtain similar information on out-of-pocket expenditure in different European countries. AIM OF THE STUDY: To estimate out-of-pocket costs paid by people who receive mental health care in six European countries (Belgium, France, Germany, Italy, the Netherlands, and Spain). METHODS: Of the 8,796 participants in a cross-sectional survey conducted in these six European countries, 1,128 reported having consulted a professional for a mental health problem in the year preceding the interview and provided information on how many times in the past year they consulted each type of provider, and the money they and their family members had paid out-of-pocket for their mental health care. In addition to sociodemographic characteristics, information on mental health status was collected using the CIDI 3.0. Descriptive statistics on out-of-pocket expenditure and share of income across countries were generated. Two-part models were employed to identify the relationship between the different covariates, notably the types of providers consulted, and out-of-pocket expenditure. RESULTS: Overall, 41.0% of those who used services for a mental health problem paid something for the care they received. This represented a minority of respondents in all countries except Belgium (87.9%) and Italy (61.7%). The financial burden of these costs relative to income was found to be low (1.2%), ranging from 0.4% in Germany to 2.3% in France. Out-of-pocket expenditure differed according to the type of providers consulted, with non-physician health professionals and medical specialists being more often associated with significant expenditure. DISCUSSION AND LIMITATIONS: Although the study is limited principally by data collection from self-report, it is the first of its kind, to our knowledge, and suggests that out-of-pocket costs for mental health care in Europe are relatively low compared to the United States. However, differences between countries exist, which may be partially due to differences in coverage for specialized care. IMPLICATIONS FOR HEALTH POLICIES: Consultations with non-physician mental health professionals such as psychologists are expensive for patients, since they are reimbursed to a lesser extent than consultations with physicians, or not reimbursed at all. This limits their role and increases the burden on psychiatrists. IMPLICATIONS FOR FURTHER RESEARCH: Monitoring out-of-pocket spending on mental health, preferably on the basis of administrative data when available, is essential in the current context of cost containment policy, where out-of-pocket spending may be expected to increase.

Smoking and the consumption of antidepressants, anxiolytics and hypnotic drugs: results of a large, French epidemiological study in 2005.

The aim of this study was to describe and analyse the links between the consumption of psychotropic drugs and smoking, based on data from individuals subscribing to a health insurance organisation (a mutuelle) in France in 2005. Data on smoking status, depression, anxiety and alcohol consumption from a large transversal epidemiological study carried out in 2005 were analysed in parallel to individual data concerning the reimbursement of medical prescriptions for psychotropic drugs. We compared reimbursement data for psychotropic drugs between individuals who had smoked for at least 15 years and continued to smoke and individuals who had stopped smoking after at least 15 years of smoking. This group of ex-smokers was subdivided into three subgroups on the basis of the number of years elapsed since the time point at which the individual had been smoking for 15 years: 1 to 9 years, 10 to 19 years and 20 years or more. "Ex-smoker" status was associated with a lower risk of psychotropic drug prescription than "current smoker" status (OR=0.81 for anxiolytics, OR=0.74 for antidepressants). Analysis of the subgroups of smokers and ex-smokers also showed that mean annual consumption of antidepressants and anxiolytics was significantly lower for individuals who had stopped smoking after at least 15 years of the habit than for those who continued to smoke (respectively 1.34 versus 0.65 for anxiolytics, and 1.17 versus 0.62 for antidepressants). Our findings suggest that stopping smoking is associated with a decrease in the consumption of psychotropic drugs. They highlight the need to evaluate the medium- and long-term effects of stopping smoking on psychotropic drug consumption in more detail, taking into account the anxious and depressive disorders to which smokers are particularly prone.

Comparing mental health of francophone populations in Canada, france, and belgium: 12-month prevalence rates of common mental disorders (part 1).

OBJECTIVE: To compare the 12-month prevalence of common mental disorders among francophones in Canada, France, and Belgium. This is the first article in a 2-part series comparing mental disorders and service use prevalence of French-speaking populations. METHODS: This is a secondary analysis of data from the Canadian Community Health Survey: Mental Health and Well-Being (CCHS 1.2) in 2002 and the European Study of Epidemiology of Mental Disorders-Mental Health Disability (ESEMeD) from 2001 to 2003, where comparable questionnaires were administered to representative samples of adults in Canada, France, and Belgium. In Canada, francophone respondents living in Quebec (n = 7571) and outside Quebec (n = 500) completed the French version of the CCHS 1.2 questionnaire. Francophone respondents in Belgium (n = 389) and in France (n = 1436) completed the French version of the ESEMeD population survey questionnaire. Major depressive episodes (MDEs), specific anxiety disorders (ADs), and alcohol abuse and (or) dependence disorders' rates were assessed. RESULTS: The overall prevalence rate for the presence of any MDE, AD, or alcohol abuse and (or) dependence was similar in all francophone populations studied in Canada and Europe and averaged 8.5%. CONCLUSIONS: Mental disorders were equally distributed in all francophone populations studied. Cross-national comparisons continue to be instrumental in providing information useful for the creation of appropriate policies and programs for specific subsets of populations.

Comparing mental health of francophones in Canada, france, and belgium: 12-month and lifetime rates of mental health service use (part 2).

OBJECTIVES: To compare 12-month and lifetime service use for common mental disorders in 4 francophone subsamples using data from national mental health surveys in Canada, Quebec, France, and Belgium. This is the second article in a 2-part series comparing mental disorders and service use prevalence of French-speaking populations. METHODS: Comparable World Mental Health-Composite International Diagnostic Interviews (WMH-CIDI) were administered to representative samples of adults (aged 18 years and older) in Canada during 2002 and in France and Belgium from 2001 to 2003. Two groups of francophone adults in Canada, in Quebec (n = 7571) and outside Quebec (n = 500), and respondents in Belgium (n = 389) and France (n = 1436) completed the French version of the population survey. Prevalence rates of common mental health service use were examined for major depressive episodes and specific anxiety disorders (that is, agoraphobia, social phobia, and panic disorder). RESULTS: Overall, most francophones with mental disorders do not seek treatment. Canadians consulted more mental health professionals than their European counterparts, with the exception of psychiatrists. CONCLUSIONS: Patterns of service use are similar among francophone populations. Variations that exist may be accounted for by differences in health care resources, health care systems, and health insurance coverage.

Child overweight, associated psychopathology, and social functioning: a French school-based survey in 6- to 11-year-old children.

The aim of this study was to estimate the prevalence of child overweight in a regional sample of primary school-aged children, and to examine the relationships among child overweight, psychopathology, and social functioning. A cross-sectional survey was conducted in 2004 in 100 primary schools of a large French region, with 2,341 children aged 6-11 randomly selected. Child weight and height, lifestyle variables (leisure-time physical activity (LTPA), watching television (TV), playing video games), and socioeconomic characteristics were collected in parent-administered questionnaires. Child psychopathology outcomes were assessed using child- and parent-reported instruments (Dominic Interactive (DI) and Strengths and Difficulties Questionnaire (SDQ)). Overweight and obesity were estimated according to the International Obesity Task Force (IOTF) definition. Response rates to the parent questionnaire and DI were 57.4 and 95.1%, respectively. Final sample size was 1,030 children. According to the IOTF, 17.3% of the children were overweight, of whom 3.3% were obese. In univariate analysis, correlates of overweight were low parental education, low monthly income, Disadvantaged School Areas (DSAs), self-reported generalized anxiety, parent-reported conduct disorders, emotional problems, and peer difficulties. High monthly income was less frequently associated with overweight. In multivariate analysis, parent-reported peer difficulties (odds ratio (OR) = 2.06; 95% confidence interval = 1.27-3.35) and DSAs (1.88; 1.03-3.44) were independent factors significantly associated with child overweight. There was a trend of being overweight with elevated TV times (P for trend = 0.02). The psychosocial burden of excess weight appears to be significant even in young children. Findings should be considered for preventing strategies and public health interventions. School-based overweight prevention programs should be implemented first in disadvantaged areas together with information about weight stigmatization and discrimination.

Prevalence of tobacco smoking in teachers following anti-smoking policies: results from two French surveys (1999 and 2005).

BACKGROUND: French public health policies aimed at reducing smoking were reinforced in France between 1999 and 2004 to decrease tobacco consumption. The consequences of these policies are of particular interest to teachers who play a role model for young people. Depression and alcohol problems were particularly studied as they may influence smoking behaviour. METHODS: Two large cross-sectional health surveys conducted in 1999 (N = 2931) and 2005 (N = 3702) included teachers, aged 20-59 years. Smoking status, socio-demographic characteristics, history of depressive episode in the previous year and problems with alcohol were collected using self-administered postal questionnaires. RESULTS: From 1999 to 2005, the prevalence of smoking decreased significantly from 25.7 to 18.2% for men (P < 0.001), from 20.0 to 16.5% (P < 0.001) for women; and the proportion of never-smokers increased. In smokers, the number of cigarettes consumed per day decreased significantly. Multivariate analysis revealed a significant decrease of the risk of being a smoker in 2005 compared with 1999 [odds ratio (OR) = 0.68 for men; OR = 0.78 for women]. Risk factors of smoking were: men aged 20-34 years (OR = 1.81), CAGE score > or =2, (OR = 1.95 for men, 2.12 for women) history of a major depressive episode in the previous 12 months (OR = 1.46 for men, 1.44 for women). CONCLUSION: Anti-smoking policies resulted in a decrease of teachers' tobacco consumption between 1999 and 2005. However, people with more difficulties in quitting smoking, in particular people with depressive episodes or problems with alcohol, might benefit from comprehensive programmes, including training of health professionals.

Religious advisors' role in mental health care in the European Study of the Epidemiology of Mental Disorders survey.

OBJECTIVE: To study the role of religious advisors in mental health problems in six European countries and to compare it to data from the USA. METHODS: Data were derived from the European Study of the Epidemiology of Mental Disorders (ESEMeD) study, a cross-sectional study, conducted in Belgium, France, Germany, Italy, the Netherlands and Spain. 21,425 individuals, 18 and older, were interviewed with the Composite International Diagnostic Interview 3.0. Findings were compared to the National Comorbidity Survey (NCS) and replication of the NCS (NCS-R) in the US. RESULTS: In ESEMeD, 0.6% of individuals (0.3% exclusively) sought help from religious advisors concerning mental health problems during the previous year, compared to 2.6% in NCS and 3.4% (for human services) in NCS-R in the US. Among those using any form of service, 6.9% consulted religious advisors (12.2% in Germany to 2.1% in Spain) compared to 18.8% in the US. Being younger (less than 25 years old), being older (more than 64) and religiosity are associated with the use of religious advisors, whereas being a student is associated with a lower probability. CONCLUSIONS: Seeking help from religious advisors for mental health problems varies dramatically among ESEMeD countries. Except for Germany, organised religion in the ESEMeD countries could not be considered as an alternative.

Validity across translations of short survey psychiatric diagnostic instruments: CIDI-SF and CIS-R versus SCID-I/NP in four European countries.

OBJECTIVES: The aims of the study are: first, to compare two short diagnostic instruments, CIDI-SF and CIS-R, with respect to the structured clinical interview for non-patient (SCID-I/NP) for anxiety and depressive disorders; and second, to evaluate the influence of four languages, Italian, Romanian, Spanish and French, on the concordance tests. METHODS: A total of 120 participants from Italy and Romania, 119 from Spain and 141 from France (N = 500) were recruited randomly in a local primary care research centre (GPs or medical centres). The instruments were administered during a unique session: the lay instruments by students in psychology and the SCID by experienced psychiatrists. Kappa, sensitivity/specificity/negative (NPV) and positive predictive values (PPV), ROC curve (AUC) and the Youden Index (Y) were calculated. RESULTS: Results were better for the CIDI-SF than the CIS-R for anxious disorders, depressive disorders and any of them. The results were identical to that obtained by the CIDI 3.0 for the three categories and constant across the languages except for depressive disorders in Romania and France. CONCLUSIONS: CIDI-SF is a cost-effective instrument and could be easily integrated into health surveys; its performance values are better across languages than values proposed by the CIS-R and could be increased by inclusion of few additional information.

Psychiatric disorders in students in six French universities: 12-month prevalence, comorbidity, impairment and help-seeking.

PURPOSE: Few studies have explored the prevalence of psychiatric disorders (PD) among university students. This article aims to study 12-month prevalence of PD in university students, their socio-economic correlates, impairment in daily life and help-seeking behaviours. METHODS: Cross-sectional study of randomly selected first-year students aged 18-24 years, enrolled in one of the six universities in south-eastern France in 2005-2006. We used the WHO CIDI-Short Form to derive DSM-IV diagnoses and the Sheehan disability scale to evaluate impairment. We studied their correlates with multiple logistic regressions. RESULTS: The 12-month prevalence of major depressive disorder (MDD), anxiety disorders (AD) and substance use disorders (SUD) were 8.9% (95% CI: 7.2-10.9), 15.7% (95% CI: 13.5-18.2) and 8.1% (95% CI: 6.7-9.8), respectively. MDD was associated with precarious economic situation (OR = 1.83; 95% CI: 1.03-3.23), AD with a precarious job or unemployment of the father (OR = 2.08; 95% CI: 1.04-4.14) and SUD with higher educational level of father (OR = 2.17; 95% CI: 1.28-3.67) or having a paid job (OR = 1.82; 95% CI: 1.06-3.13). "Marked" or "extreme" impairment (score > or =7 for at least one of the domains in the Sheehan scale) was noted for 51.7% of students presenting a PD and was even more frequent in the presence of MDD/AD comorbidity. Only 30.5% of the students with a PD had sought professional help in the past 12 months. CONCLUSIONS: This study provides new results regarding university students suggesting a link between precarious economic situations and MDD. The frequent impairment arising from PD alongside low rates of help-seeking suggests that PD could be one of the factors in academic failure in first year of university. These results should be used to improve prevention and care of PD in university students in France.
