A Nationwide, Population-Based Study of Intelligence and Hearing Loss among 3,104,670 Adolescents.

Purpose: Epidemiological studies have demonstrated a relationship between general intelligence (GI) in youth and hearing loss (HL). However, no large-scale study assessed the relations of GI in late adolescence with conductive HL (CHL) and sensorineural HL (SNHL), stratified by severity. This study examined the connection between HL and GI in late adolescence.
