title: Gender differences in obsessive-compulsive symptom dimensions.
abstract: The aim of our study was to assess the role of gender in OCD symptom dimensions with a multivariate analysis while controlling for history of tic disorders and age at onset of OCD. One hundred and eighty-six consecutive outpatients with a DSM-IV diagnosis of OCD were interviewed. Yale-Brown Obsessive-Compulsive Scale (YBOC-S), YBOC-S Symptom Checklist, and Hamilton Depression and Anxiety Scales were administered to all patients. Lifetime history of tic disorders was assessed with the tic inventory section of the Yale Global Tic Severity Scale. Age at onset of OCD was assessed by direct interview. Statistical analysis was carried out through logistic regression to calculate adjusted female:male odds ratios (OR) for each dimension. A relationship was found between gender and two main OCD dimensions: contamination/cleaning (higher in females; female:male OR=2.02, P=0.03) and sexual/religious (lower in females; female:male OR=0.41, P=0.03). We did not find gender differences in the aggressive/checking, symmetry/ordering, or hoarding dimensions. We also found a greater history of tic disorders in those patients with symptoms from the symmetry/ordering, dimension (P<0.01). Both symmetry/ordering and sexual/religious dimensions were associated with an earlier age at onset of OCD (P<0.05). Gender is a variable that plays a role in the expression of OCD, particularly the contamination/cleaning and sexual/religious dimensions. Our results underscore the need to examine the relationship between OCD dimensions and clinical variables such as gender, tics, age at onset and severity of the disorder to improve the identification of OCD subtypes.
