Clinical Correlates of Carbon Dioxide Hypersensitivity in Children.

ABSTRACT:

Objective

Hypersensitivity to carbon dioxide (CO₂)-enriched air may be a promising risk marker for anxiety disorders. Among adult and adolescent samples, heterogeneity in distress response to the CO₂ challenge task indexes 3 underlying classes of individuals, which distinguish between sustained and acute threat response as markers for internalizing disorders, broadly, and anxiety disorders, specifically. The present study examines latent classes in children's response to the CO₂ challenge task to clarify the association of CO₂ hypersensitivity with anxiety and internalizing symptomatology in childhood.

Method

Healthy children from a community twin sample (N = 538; age 9-13 years) rated anxious distress every 2 minutes while breathi
