  • Abstract: Abstract: Background:

    Obsessive-compulsive disorder can be expressed as four potentially overlapping obsessive-compulsive symptom (OCS) dimensions (OCSD) ("symmetry/ordering", "contamination/cleaning", "aggressive/sexual/religious" and "collecting/hoarding"). In clinical samples, some dimensions are more familial and associated with increased psychiatric comorbidity and malfunctioning. However, data concerning OCS and OCSD are scarce in non-clinical samples, particularly among children. The present study aims to estimate: (1) the prevalence and sex/age distribution of OCS/OCSD in a community-based sample of schoolchildren; (2) the association between OCS and additional clinical factors; and (3) the degree of familial aggregation of OCS/OCSD.

    Methods:

    OCS and OCSD were evaluated in 9937 Brazilian school-children (6–12 years-old) and their biological relatives using the Family History Screen . Data analyses included gradient estimated equations and post-hoc tests.

    Results:

    We included data on 9937 index-children, 3305 siblings (13–18 years-old), and 16, 218 parents. Biological mothers were the informants in 87.6% of the interviews. OCS were present in 14.7% of the index-children; 15.6% of their siblings; 34.6% of their mothers and 12.1% of their fathers. The prevalence of OCS and each of the OCSD gradually increased from ages 6 to 12 years. Overall, OCS in children were associated with the presence of other psychiatric symptoms, as well as behavioral/school impairment. OCS and each of the four OCSD aggregated significantly within families.

    Conclusions:

    OCS are prevalent and associated with psychiatric symptoms and clinical impairment among school-aged children. OCSD aggregate within families in a dimension-specific fashion. These findings suggest a natural continuum between OCS and OCD with regard to their dimensional character.

    Highlights:

    Prevalence of obsessive-compulsive symptoms in school-aged children is around 15%.

    Obsessive-compulsive symptoms were associated with increased age and male gender in school-aged children.

    Obsessive-compulsive symptom dimensions aggregate in families.

    Obsessive-compulsive symptoms in school-aged children are associated with psychiatric symptoms.

    Obsessive-compulsive symptoms in school-aged children are associated with functional impairment.
