Prevalence, comorbidities and mediators of childhood anxiety disorders in urban Turkey: a national representative epidemiological study

PURPOSE

The aim of this study is to evaluate the prevalence of anxiety disorders, its correlation with sociodemographic characteristics, its comorbidities with other psychiatric disorders and its predictors in school-aged children.

METHODS

This study is part of a representative, multi-centered national study that is planned by the Turkish Association of Child and Adolescent Mental Health to evaluate the prevalence of psychopathology among elementary school students in Turkey between the years 2014-2015. Children are screened via Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime Version. Impairment is assessed by a 3-point Likert type scale independently by the parent and the teacher. The final sample included 5842 children with the mean age of 8.7 years.

RESULTS

The prevalence of any anxiety disorder without considering impairment is 16.7% and considering impairment is 5.2% in children according to our study. We found significant differences for comorbid Attention Deficit Hyperactivity Disorder, Disruptive Behavior Disorder, Mood Disorders, Tic Disorders, Obsessive Compulsive Disorder, Enuresis Nocturna, Encopresis, and Intellectual Disability. Having a history of paternal physical disorder, living in the regions of Marmara, Mediterranean and Black Sea were found to be the main predictors of having childhood anxiety disorders according to the logistic regression analysis.

CONCLUSION

Better understanding of childhood anxiety disorders, comorbid conditions and predictors will result in earlier diagnosis and more appropriate treatment.

The prevalence of childhood psychopathology in Turkey: a cross-sectional multicenter nationwide study (EPICPAT-T)

AIM

The aim of this study was to determine the prevalence of childhood psychopathologies in Turkey.

METHOD

A nation-wide, randomly selected, representative population of 5830 children (6-13 years-old) enrolled as a 2nd,3rd or 4th grade student in 30 cities were evaluated for presence of a psychiatric or mental disorder by a Sociodemographic Form, Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), and DSM-IV-Based Screening Scale for Disruptive Behavior Disorders in Children and Adolescents scales. Impairment criterion was assessed via a 3 point-Likert scale by the parent and the teacher independently.

RESULTS

Overall prevalence of any psychopathology was 37.6% without impairment criterion, and 17.1% with impairment criterion. Attention-deficit hyperactivity disorder was the most frequent diagnosis, followed by anxiety (19.5% and 16.7% without impairment, 12.4% and 5.3% with impairment, respectively). Lower education level and presence of a physical or psychiatric problem of the parents were independent predictors of any psychopathology of the offspring.

CONCLUSION

This is the largest and most comprehensive epidemiological study to determine the prevalence of psychopathologies in children and adolescents in Turkey. Our results partly higher than, and partly comparable to previous national and international studies. It also contributes to the literature by determining the independent predictors of psychopathologies in this age group.

Is there a relationship between attention deficit/hyperactivity disorder and manic symptoms among children with mental retardation of unknown etiology?

Mental retardation (MR) is common and lifelong. In children and adolescents with MR, the rate of attention deficit/hyperactivity disorder (ADHD) and bipolar disorder is higher than that in the general population. However, there are no previous sufficient data that exist in establishing a relationship between ADHD and manic symptoms. The aim of the present study was to examine the relationship between manic symptoms and ADHD as well as oppositional-defiant disorder (ODD) and conduct disorder (CD) in children with MR of unknown etiology (MR-UE). A total of 167 children with MR-UE attending a rehabilitation and training school in Erzurum, Turkey, were included in the study. We administered the Child Disruptive Behavior Screening and Rating Scale related to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition and the Young Mania Rating Scale-Parent Version (P-YMRS) to parents. The age range of children and adolescents with MR-UE was between 5 and 21 years, with a mean age of 11.13 ± 3.75 years. In total, 5.8% of children and adolescents with MR-UE showed a border intelligence quotient (IQ), with 58.4% having a mild IQ, 29.2% having a moderate IQ, and 6.6% having severe IQ. According to the Child Disruptive Behavior Screening and Rating Scale related to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, 40.1% of children and adolescents with MR-UE had inattention, 19.9% had hyperactivity, 28.7% had ODD, and 13.3% had CD. A total of 7.2% of the children and adolescents with MR-UE had probable mania, and 1.8% had mania according to Young Mania Rating Scale-Parent Version. A positive correlation existed between the mean scores of Young Mania Rating Scale-Parent Version and the mean scores of inattention, hyperactivity, ODD, and CD (P = .000). Hyperactivity and ODD were predictors of being manic/probably manic. Diagnosing psychiatric disorders in children and adolescents with MR-UE is difficult but essential for better functioning. Manic symptoms and disruptive behaviors as well as ADHD symptoms were prevalent among children and adolescents with MR-UE and hyperactivity, and oppositional-defiant symptoms were predictors of manic symptoms in these patients.

Munchausen's Syndrome

Although the differential diagnosis of hemoptysis is extensive, consideration of a factitious cause is rarely contemplated. Factitious hemoptysis is uncommon in children. We report a dramatic case of factitious hemoptysis in a 12-year-old girl. The features of Munchausen's syndrome are also reviewed.
