Abstract

Objectives/Hypothesis To evaluate the association between hearing loss and nonverbal intelligence in US children. Study Design The Third National Health and Nutrition Examination Survey (NHANES III) is a cross-sectional survey (1988-1994) that used complex multistage sampling design to produce nationally representative demographic and examination data. Methods A total of 4,823 children ages 6 to 16 years completed audiometric evaluation and cognitive testing during NHANES III. Hearing loss was defined as low-frequency pure-tone average (PTA) >25 dB (0.5, 1, 2 kHz) or high-frequency PTA >25 dB (3, 4, 6, 8 kHz) and was designated as unilateral or bilateral. Nonverbal intelligence was measured using the Wechsler Intelligence Scale for Children-Revised block design subtest. Low nonverbal intelligence was defined as a standardized score
