“…22,23 Patients visiting emergency departments were not included because TPL chez les femmes est plus faible après le milieu des années 1990, après contrôle pour les patients externes obligatoirement inscrits depuis 1995. 2 Before that, ICD-8 was the official diagnostic classification system.…”

Objectives: To investigate whether there are any trends in treated incidence of borderline personality disorder (BPD) in Danish psychiatric hospitals based on different diagnostic systems from 1970 to 2009. Methods:All patients diagnosed with BPD for the first time as a main or an auxiliary diagnosis treated in in-or outpatient facilities in Danish psychiatric hospitals were identified through the Danish Psychiatric Central Research Register. Age-standardized, sex-specific, and standardized rates were calculated for the International Classification of Diseases Conclusion:The lack of defined criteria for BPD in ICD-8 may have been interpreted broadly to mean Kernberg's overarching concept of borderline personality organization, resulting in similar rates for males and females. However, in ICD-10, clinicians using the more narrow criteria for emotionally unstable personality disorder (borderline type), tended to diagnose BPD more commonly in women. These results suggest the importance of using specific criteria in diagnosing. They also suggest the importance of stability in the diagnostic criteria for BPD and other disorders. W W W Changements de l'incidence traitée du trouble de la personnalité limite au Danemark : 1970-2009Objectifs : Rechercher s'il y a des tendances dans l'incidence du trouble de la personnalité limite (TPL) traité dans des hôpitaux psychiatriques danois selon différents systèmes diagnostiques, de 1970 à 2009. Méthodes :Tous les patients ayant reçu un diagnostic de TPL pour la première fois comme diagnostic principal ou auxiliaire et traités comme patients externes ou hospitalisés d'hôpitaux psychiatriques danois ont été identifiés grâce au registre danois central de recherche en psychiatrie. Les taux normalisés selon l'âge, le sexe, ont été calculés avec la Classification internationale des maladies (CIM), 8e révision, pour la période diagnostique de 1970 à 1993 et la CIM-10 pour la période diagnostique de 1994 à 2009.

Objective: Is an increased focus on eating disorders during the past few decades reflected by increasing occurrence in the psychiatric health service system. Method:All first-time diagnoses of eating disorders identified in the Danish Central Psychiatric Research Register 1970-2008 constitute the present research database. Age-standardized rates per 100,000 inhabitants were calculated and autoregressive models were fitted for males and females separately as well as for in-and outpatients.Results: The incidence of eating disorders diagnosed in Danish psychiatric secondary healthcare has increased considerably during a nearly 40-year period of observation both within the general category of eating disorders and also specifically for anorexia nervosa. The steepest increase is seen within females aged 15-19 years, where the highest incidences are also found. Anorexia nervosa constitutes the vast majority of all eating disorders. Throughout the time interval investigated, the number of males, however, is negligible compared to females. Most patients are seen in outpatient services, increasing towards recent years. However, the number of patients being treated as inpatients has increased linearly through the entire four decenniums investigated. Conclusions:Changes in registration principles, public awareness and higher acceptance of mental disorders in the public is the most obvious explanation for the incidence increase of anorexia nervosa and other eating disorders. This study does not answer whether there has been an increase in true incidence in the population.

“…[31][32][33] Diagnoses were based on ICD-8 criteria in the 1969-1994 period and on ICD-10 diagnoses since 1995 whereas the ICD-9 classification had never been in use in Denmark. In Danish psychiatry, assessment and diagnosis is carried out by specialists in psychiatry and in an interdisciplinary setting consisting of psychiatrists, psychologists, social workers, nurses, and others.…”

Objective: There is conflicting evidence as to whether or not the incidences of affective disorders are on the rise. The aim of the present study was to identify time trends across 16 years in the incidences of affective disorders in a nationwide sample. Methods: Using the Danish Psychiatric Central Research Registry, age-and sexadjusted incidence rates of diagnosed affective disorders in Danish psychiatric hospitals using ICD-10 classification were calculated per 100,000 person-years for the population aged 4-65 years during the period 1995-2010. Results: Incidence rates of diagnosed bipolar disorder increased from 11.5 to 24.5, and there was an increase from 86.2 to 189.7 per 100,000 person-years for depression. Time trends were most pronounced for individuals up to 29 years of age. A sizeable part of the increase in incidence rates could be attributed to an increase in the total number of persons diagnosed in psychiatry. Conclusions: Time trends in incidence ratesshowed an increase for bipolar disorder and depressive disorders across 16 years, but found that some of the observed increase in incidence rates was related to a more widespread trend in Danish society of seeking and receiving psychiatric assistance.
