“…[50] Despite this cross-national variability in prevalence, the epidemiology of OCD shows substantial similarity in gender distribution, age of onset, and comorbidity. [103] In particular, OCD is more common across several cultural settings in male children and adolescents and in female adults; late adolescence is a period of increased vulnerability, and individuals with OCD often have comorbid mood and anxiety disorders.…”

Background-The anxiety disorders specified in the fourth edition, text revision, of The Diagnostic and Statistical Manual (DSM-IV-TR) are identified universally in human societies, and also show substantial cultural particularities in prevalence and symptomatology. Possible explanations for the observed epidemiological variability include lack of measurement equivalence, true differences in prevalence, and limited validity or precision of diagnostic criteria. One central question is whether, through inadvertent "over-specification" of disorders, the post-DSM-III nosology has missed related but somewhat different presentations of the same disorder because they do not exactly fit specified criteria sets. This review canvases the mental health literature for evidence of cross-cultural limitations in DSM-IV-TR anxiety disorder criteria.

“…Epidemiological studies of OCD have suggested sex difference in the prevalence of OCD. Among children and adolescents, symptoms of OCD are more frequent in males than in females, but the prevalence is reversed in adults (Fireman et al, 2001;Fontenelle & Hasler, 2008;Heyman et al, 2001). Sex differences in clinical features of OCD have also been noted.…”

Recent molecular genetic studies provide suggestive evidence for sexual dimorphism in genetics of obsessive-compulsive disorder. However, only a few twin studies have addressed the question of sex differences in genetic and environmental contributions to variation of obsessive–compulsive symptoms. The aim of the present study was to estimate genetic and environmental influences on obsessive–compulsive symptoms in South Korean twins, with a special emphasis on sex difference. In total, 751 adolescent and young adult twin pairs (ages: 13–23 years) completed a Korean version of the 30 items of the Maudsley Obsessional — Compulsive Inventory (MOCI) through a mail survey. A sum of the answers for the 30 items was calculated to represent a total score for obsessive–compulsive symptoms (hereafter, the MOCIT). Males had significantly higher variance of the MOCIT than did females. In males, monozygotic (MZ) twin correlation was significantly higher than dizygotic (DZ) twin correlations (.56 vs. .24), whereas in females, MZ and DZ twin correlations were not significantly different from each other (.39 vs. .36). The general sex-limitation model was applied to the twin data. The results of model-fitting analyses indicated that the unstandardized genetic variance as well as heritability estimate (53% vs. 41%) for the MOCIT was higher in males than in females. However, shared environmental influences did not attain statistical significance perhaps due to insufficient statistical power.

“…In some studies OCD is reported to be seen equally common in males and in females and clinical reports of childhood OCD find that males outnumber females [15][16][17]. This discrepancy requires further investigation as social and cultural factors may be associated with the occurrence of OCD.…”

Objectives: Obsessive-compulsive disorder (OCD) often starts in childhood and adolescence and can be a chronic disorder with high persistence rates. The prevalence of OCD in this group is between 0.5-4%. It may occur in children as young as 6-7 years of age. The aim of the present study is to explore suggestive OCD in adolescents in a public high school and factors related with suggestive OCD. Patients and Methods:Ninth, 10th, 11th and 12th grade students attending a public high school were included in the study. In our study, we used a questionnaire made up of a sociodemographic survey form and the Leyton's Obsessional Inventory. The inventory was applied as a self-report questionnaire.Results: A high suggestive OCD prevalence was found among students (14.3%). Students who declared to be traumatized in childhood had 3,55 times higher odds to exhibit suggestive OCD than those who declared to be not traumatized. Also students who reported to possess a psychological disorder had 2,22 times higher odds to exhibit suggestive OCD than students who reported not having a psychological disorder. Conclusion:The prevalence of suggestive OCD was high in students who participated to our study. More comprehensive studies are needed to be done. Keywords:Suggestive obsessive-compulsive disorder, Superstition, Trauma, High school ÖZ Amaç: Obsesif-kompulsif bozukluk (OKB) genellikle çocukluk ve ergenlik döneminde başlayabilir ve kronik bir rahasızlık haline gelebilir. OKB'nin çocuk ve yetişkinlerdeki prevelansı 0,5% ile 4% arasında değişmektedir. OKB 6-7 yaşlarında başlayabilmektedir ve her iki cinsiyet grubunda eşit oranda gözlenmektedir. Amacımız bir devlet lisesine kayıtlı öğrencilerde muhtemel OKB sıklığını ve ilişkili faktörleri incelemektir. Hastalar ve Method:Bir devlet lisesindeki 9, 10, 11 ve 12. sınıf öğrenciler araştırmaya dahil edilmiştir. Öğrencilere sosyodemoğrafik değişkenleri ve Leyton obsesyon skalasını da içeren bir soru formu uygulanmıştır. Anketler öğrencilerin kendi bildirimlerine göre doldurulmuştur. Bulgular: Çalışmamızda muhtemel OKB sıklığı öğrencilerde yüksek bulunmuştur (14,3%). Çocukluk çağında travma yaşayan öğrencilerde diğerlerine göre 3,55 kat daha yüksek oranda muhtemel OKB mevcut idi. Ayrıca psikolojik bozukluğu olduğunu ifade eden öğrencilerin psikolojik bozukluğu olmadığını bildiren öğrencilere göre muhtemel OKB görülme oranı 2,22 kat daha fazla bulunmuştur.Sonuç: Araştırmamıza katılan öğrencilerde muhtemel OKB sıklığı beklenenin üzerinde çıkmıştır. Bu sonuç ülkemiz genelinde daha kapsamlı bir çalışmaya ihtiyaç olduğunu göstermektedir.
