Prevalence, characteristics and comorbidities of anxiety disorders in France: results from the "Mental Health in General Population" survey (MHGP).
ABSTRACT Only a few European countries have carried out large, community-based, national surveys about psychiatric morbidity. Here is presented the first national French survey, aiming to estimate the prevalence of anxiety disorders and associated comorbidities according to sociodemographic characteristics.
The Mental Health in General Population (MHGP) database is derived from a representative national survey of the French adult population (n=36,105), conducted between 1999 and 2003. Data collection was done using an anonymous face-to-face interview. The presence of anxiety disorders (generalized anxiety disorder, panic disorder, agoraphobia, social phobia and post-traumatic stress disorder) was assessed using the Mini International Neuropsychiatric Interview.
The overall prevalence of anxiety disorders was estimated to be 21.6%, generalized anxiety disorder being the most prevalent one (12.8%). Women, young people, and people earning low income were identified as the more at risk. Major depressive episode, alcohol abuse and drug addiction frequently co-occur with anxiety disorders (28.3, 4.4 and 2.8% respectively).
The MHGP study showed that anxiety disorders are highly prevalent in France with a high frequency of comorbidities. Our results highlight the need for considering anxiety disorders as a public health priority in France as well as in other European countries.

ABSTRACT: This article discusses the effects of sociodemographics and the presence of psychiatric disorders diagnosed in the 12 months before the first interview by using the Diagnostic and Statistical Manual of Mental Disorders: DSM-III-R, third edition, revised, on three types of attrition (failure to locate, refusal to participate, morbidity/mortality) in the second wave (1997-1998) of the Netherlands Mental Health Survey and Incidence Study, a longitudinal, general population survey of psychopathology among 7,076 subjects aged 18-64 years. Compared with those reinterviewed successfully, persons not located at the 1-year follow-up (n = 219) were more often younger, poorly educated, urban, not cohabiting with a steady partner, and born outside the Netherlands. Refusers (n = 923) had a lower educational level. Morbidity/mortality (n = 72) was associated with higher age, lower educational level, not being employed, and somatic disorders. After adjustment for sociodemographics, none of the disorders was positively associated with refusal. Failure to locate was linked to agoraphobia, alcohol abuse, and the categories of mood, substance use, and eating disorders. Morbidity/mortality was linked to dysthymia, agoraphobia, simple phobia, obsessive-compulsive disorder, and the category of anxiety disorders. Overall attrition was only slightly higher among respondents with one or more disorders (odds ratio = 1.20, 95% confidence interval: 1.04, 1.38). Thus, psychopathology has only weak-to-moderate effects on attrition and is mainly related to failure to locate and morbidity/mortality but not to refusal.American Journal of Epidemiology 01/2001; 152(11):1039-47. · 4.78 Impact Factor

ABSTRACT: Data are presented on the general population prevalences, correlates, comorbidities, and impairments associated with DSM-III-R phobias. Analysis is based on the National Comorbidity Survey. Phobias were assessed with a revised version of the Composite International Diagnostic Interview. Lifetime (and 30-day) prevalence estimates are 6.7% (and 2.3%) for agoraphobia, 11.3% (and 5.5%) for simple phobia, and 13.3% (and 4.5%) for social phobia. Increasing lifetime prevalences are found in recent cohorts. Earlier median ages at illness onset are found for simple (15 years of age) and social (16 years of age) phobias than for agoraphobia (29 years of age). Phobias are highly comorbid. Most comorbid simple and social phobias are temporally primary, while most comorbid agoraphobia is temporally secondary. Comorbid phobias are generally more severe than pure phobias. Despite evidence of role impairment in phobia, only a minority of individuals with phobia ever seek professional treatment. Phobias are common, increasingly prevalent, often associated with serious role impairment, and usually go untreated. Focused research is needed to investigate barriers to help seeking.Archives of General Psychiatry 03/1996; 53(2):159-68. · 13.77 Impact Factor

ABSTRACT: Nationally representative general population data are presented on the current, 12-month, and lifetime prevalence of DSM-III-R generalized anxiety disorder (GAD) as well as on risk factors, comorbidity, and related impairments. The data are from the National Comorbidity Survey, a large general population survey of persons aged 15 to 54 years in the noninstitutionalized civilian population of the United States. DSM-III-R GAD was assessed by lay interviewers using a revised version of the Composite International Diagnostic Interview. Generalized anxiety disorder was found to be a relatively rare current disorder with a current prevalence of 1.6% but was found to be a more frequent lifetime disorder affecting 5.1% of the US population aged 15 to 45 years. Generalized anxiety disorder was twice as common among women as among men. Multivariate logistic regression analysis showed that being older than 24 years, separated, widowed, divorced, unemployed, and a homemaker are significant correlates of GAD. Consistent with studies in treatment samples, we found that GAD was frequently associated with a wide spectrum of other mental disorders, with a lifetime comorbidity among 90.4% of the people who had a history of GAD. Contrary to the traditional view that GAD is a mild disorder, we found that the majority of people with GAD, whether they were comorbid or not, reported substantial interference with their life, a high degree of professional help seeking, and a high use of medication because of their GAD symptoms. Although lifetime GAD is highly comorbid, the proportion of current GAD that is not accompanied by any other current diagnosis is high enough to indicate that GAD should be considered an independent disorder rather than exclusively a residual or prodrome of other disorders.Archives of General Psychiatry 06/1994; 51(5):355-64. · 13.77 Impact Factor
